# How Much Is My House Worth? 7 Ways to Find Out Your Home's Value By Opendoor Editorial Team | 2026-03-10 Your home is likely the single largest financial asset you own — yet most homeowners have only a vague idea of what it's actually worth today. If you've ever wondered how much is my house worth, you've probably typed that question into a search bar, gotten a number, and then found a completely different number on another site. That's not a glitch. It's a feature of a fragmented system where different tools use different data, different methods, and different assumptions. Here's the truth: no single method gives you a perfect answer. But by combining multiple approaches, you can zero in on a realistic range that helps you make smart decisions — whether you're [preparing to sell](https://www.opendoor.com/articles/how-to-sell-your-house), refinancing, or just keeping tabs on your equity. This guide covers seven proven methods for determining your home's value, ordered from the quickest and cheapest to the most thorough and accurate: - **Free online home value estimators (AVMs)** - **Comparative market analysis (CMA) from a real estate agent** - **iBuyer offers** - **DIY comparable sales analysis** - **County tax assessments** - **Professional appraisals** - **The FHFA House Price Index Calculator** Let's break down each one so you know exactly which to use — and when. [Get your offer](#) ## What Determines Your Home's Value? Before diving into the methods, it helps to understand the [factors that influence home value](https://www.opendoor.com/articles/factors-that-influence-home-value) in the first place. The biggest drivers include **location**, square footage, lot size, the number of bedrooms and bathrooms, overall condition, age of the home, and recent comparable sales in your neighborhood. Beyond the physical property, broader forces matter too: local market conditions, school district quality, neighborhood trends, interest rates, and even seasonality all play a role. It's also critical to understand three terms that homeowners commonly confuse: - **Market value** is what a willing buyer would actually pay for your home in the current market. This is the number most sellers care about. - **Appraised value** is the figure a licensed appraiser determines after a professional evaluation. Lenders rely on this number when approving mortgages. - **Assessed value** is what your county assigns for property tax purposes. This is often significantly different from what your home would sell for. (We have a full guide on assessed value vs. market value that explains this in detail.) One thing every homeowner should internalize: your home's value is not static. It shifts with [market conditions](https://www.opendoor.com/articles/understanding-fundamentals-of-real-estate-market), seasonal demand, interest rate movements, and changes in your neighborhood. A value from six months ago may no longer be accurate today, which is why understanding home value appreciation trends matters. Finally, renovations *can* increase your home's value — but the return on investment varies wildly by project type. We'll address that later in this article. ## 7 Ways to Find Out How Much Your House Is Worth Here are seven methods for estimating your home's value, starting with the fastest free options and progressing toward the most precise professional evaluations. For the best results, use at least two or three of these approaches together. ### 1. Use Free Online Home Value Estimators (AVMs) The fastest way to get a ballpark figure is through an Automated Valuation Model — the technology behind the home value estimators you'll find on sites like Zillow, Redfin, and Realtor.com. AVMs work by pulling publicly available data — tax records, MLS listings, recent sale prices, neighborhood trends — and running it through algorithms that estimate your home's worth. You type in your address, and within seconds, you get a number. It's instant, it's free, and it's a perfectly reasonable starting point. But it's just that — a starting point. [According to analysis by Clever Real Estate](https://listwithclever.com/real-estate-blog/home-value-estimate-websites/), even the best online estimators carry median error rates between roughly 2% and 7.5% depending on whether the home is currently listed for sale or not. For on-market homes, the algorithms have more data to work with and tend to be more accurate. For off-market homes — which is most homeowners checking their own property — the error margin widens. On a $400,000 home, a 7% error means the estimate could be off by **$28,000 or more** in either direction. That's a significant gap when you're making financial decisions. The key limitation of AVMs is what they *can't* see. These algorithms have no idea whether you renovated your kitchen last year, whether your basement has water damage, or whether your home sits on the best lot in the subdivision. They can't account for interior condition, unique architectural features, or hyperlocal quirks like a noisy highway behind the tree line. They also tend to perform worse in rural areas, markets with few recent sales, or for truly custom or unusual properties. **Best practice:** Check your estimate on multiple estimator tools and average the results. As Clever Real Estate puts it: ["Compare home values from multiple estimators and averaging the values for a clearer picture of your home's value. Even then, this is just a ballpark estimate and shouldn't be used for making major financial decisions."](https://listwithclever.com/real-estate-blog/home-value-estimate-websites/) If you want to explore which tools perform best, our guide to the best home value estimators and our comparison of branded estimators go deeper. ### 2. Get a Comparative Market Analysis (CMA) from a Real Estate Agent A comparative market analysis is a detailed report prepared by a licensed real estate agent that examines recent sales of comparable properties (called "comps"), active listings, and expired listings in your area to estimate your home's value. Unlike AVMs, a CMA benefits from human judgment. An experienced local agent knows that the comp down the street sold for less because it backs up to a commercial property, or that homes on your side of the school boundary consistently command a premium. They can adjust for your home's specific condition, upgrades, and curb appeal in ways that no algorithm can. The best part? CMAs are typically **free**. Agents offer them as a service — partly to demonstrate their market knowledge, and partly because they hope to earn your listing if you decide to sell. There's no obligation. **How to get one:** Contact two or three local agents and request a CMA from each. Comparing their analyses gives you a range and also helps you evaluate which agent understands your market best — useful if you're [preparing to sell your house](https://www.opendoor.com/articles/how-to-sell-your-house-for-the-most-money). One important clarification: a CMA is an *informed professional opinion*, not a certified valuation. It carries no legal weight like an appraisal does. But for most homeowners exploring their options, it's the sweet spot between a quick online estimate and a full appraisal — and it's free. Learn more in our complete guide to understanding home value. ### 3. Request an iBuyer Offer iBuyers — companies like Opendoor, Offerpad, and Knock — use algorithmic pricing models to make cash offers on homes, often within a few business days. While the primary purpose of an iBuyer offer is to give you a convenient, fast selling option, it can also serve as a useful data point for understanding your home's value. However, it's important to understand what an iBuyer offer actually represents. These companies need to account for their own service fees, estimated repair costs, and profit margins. As a result, iBuyer offers typically come in **below full market value** — sometimes significantly so. Reports indicate sellers can net substantially less through an iBuyer transaction compared to a [traditional home sale](https://www.opendoor.com/articles/how-selling-to-opendoor-compares-to-a-traditional-home-sale). Each iBuyer operates differently. Some charge service fees comparable to standard real estate commissions. Others use a bridge-loan model that lets you buy a new home before selling your current one. Some offer flexible closing timelines, while others have strict purchase criteria. And across the board, repair cost deductions during the inspection process can substantially reduce what you ultimately receive. **The key takeaway:** An iBuyer offer is useful as a *value floor* — it tells you the minimum someone is willing to pay for your home right now, with speed and certainty as the trade-off. It is **not** market value. Think of it as one data point, not the final answer. If you're exploring a [cash offer](https://www.opendoor.com/articles/what-is-a-cash-offer-in-real-estate-and-why-consider-it), it's wise to compare it against a CMA and at least one other valuation method so you understand exactly what you'd be leaving on the table — or gaining in convenience. And note: you can typically use your own realtor when working with most iBuyer companies. For a broader look at the selling process and what to expect financially, see our guides on [how much it costs to sell a house](https://www.opendoor.com/articles/how-much-does-it-cost-to-sell-a-house) and [closing costs for sellers](https://www.opendoor.com/articles/how-much-are-closing-costs-for-seller). ### 4. Check Recent Comparable Sales (Comps) Yourself You don't need a real estate license to do basic comp research. With publicly available data, you can get a reasonable sense of what homes like yours are selling for. Here's how to run a DIY comp analysis: 1. **Define your search area.** Look for homes within 0.25 to 0.5 miles of your property. 2. **Filter by recency.** Focus on sales from the last three to six months. Older sales may not reflect current conditions. 3. **Match key characteristics.** Prioritize homes with similar square footage (within 10–15%), the same bedroom and bathroom count, comparable lot size, and similar age and condition. 4. **Adjust for differences.** If a comp has a feature yours doesn't — an extra bathroom, a finished basement, a two-car garage — adjust the value accordingly. An additional bathroom, for example, may add meaningful value depending on your market and what comparable homes nearby offer. **Where to find comps:** Most major real estate websites let you filter for recently sold homes. County assessor websites also publish sale records. For the most complete data, ask a real estate agent for MLS access — the [comps available through the MLS](https://www.opendoor.com/articles/home-sellers-why-you-should-care-about-comps) are more detailed and reliable than what you'll find on consumer-facing sites. There's one major pitfall with this approach: **objectivity**. Most homeowners overestimate their home's condition and the value of their personal upgrades. That kitchen remodel you spent $50,000 on may add only a fraction of that cost in market value. Try to be brutally honest — or better yet, use this as a supplement to a CMA or appraisal, not a replacement. You can also look up any home's value by address using free public tools to quickly pull comp data in your neighborhood. ### 5. Review Your County Tax Assessment Every homeowner receives an annual property tax assessment from their county assessor's office. This document lists your property's assessed value — the figure the county uses to calculate your property taxes. It's free, it's easy to find, and it's worth looking at. But here's the critical caveat: **assessed value is not market value.** In many areas, assessed values lag behind the market and can diverge significantly from what your home would actually sell for. In declining markets, the opposite can happen — assessed values may temporarily exceed what buyers are willing to pay. **How to find it:** Search "\[your county\] property assessor" online, or check your most recent property tax statement. Many counties offer online portals where you can look up any property's assessed value instantly. Your tax assessment is useful as a baseline reference point, especially for tracking changes over time. But don't rely on it to set a list price or make a financial decision. For a deeper explanation of how tax assessments work and why they diverge from market value, see our guide to assessed value vs. market value. ### 6. Hire a Professional Appraiser If you want the most defensible, accurate valuation available, hire a licensed appraiser. Among the options available to homeowners, a professional appraisal is generally the most reliable. During an [appraisal](https://www.opendoor.com/articles/home-appraisal-process), a certified professional physically inspects your property — evaluating its condition, measuring square footage, noting upgrades and deficiencies, photographing the interior and exterior, and then analyzing recent comparable sales. The result is a certified valuation report that carries legal and financial weight. **Cost:** Fees for a standard single-family home appraisal commonly fall in the **$300–$600 range**, though this varies by location and property complexity — larger, custom, or rural homes often cost more. **When it makes sense to order one:** - You're refinancing (your lender will likely require it) - You're contesting your property tax assessment - You're going through a divorce or settling an estate - You want the most accurate number possible before [listing your home](https://www.opendoor.com/articles/how-to-sell-your-house) - You're making major financial decisions based on your home equity Appraisals combine everything the other methods offer — data analysis, comparable sales, physical inspection, and professional judgment — into a single, certified report. If you've ever wondered [what appraisers actually look for](https://www.opendoor.com/articles/items-that-increase-your-home-appraisal-value-what-appraisers-actually-look-for), or need to know [how long an appraisal takes](https://www.opendoor.com/articles/how-long-does-an-appraisal-take), we cover both topics in detail. One note: a lender-ordered appraisal (done during a mortgage or refinance) may differ from a private appraisal because the intended use and audience are different. Both are valid, but they serve different purposes. Our full [home appraisal guide](https://www.opendoor.com/articles/home-appraisal-guide-what-it-is-how-long-it-takes-what-to-expect) walks through the entire process. ### 7. Use the FHFA House Price Index Calculator This is a lesser-known but genuinely useful free tool. The Federal Housing Finance Agency (FHFA) maintains a House Price Index Calculator that estimates how your home's value has changed since you purchased it, based on regional price trends. **How it works:** Enter your original purchase price, the date you bought the home, your state, and your metro area. The calculator applies average regional appreciation rates to estimate your home's current value. **The limitation:** This tool tracks broad market trends, not your specific home's condition or improvements. If you renovated heavily or let the property deteriorate, the calculator won't reflect that. It also won't capture hyperlocal variations — one neighborhood in a metro area might appreciate faster than another. That said, if you've owned your home for many years and want a quick sense of how much equity you've built through appreciation alone, the FHFA calculator is a solid starting point. Pair it with an AVM or CMA for a more complete picture. For more context on long-term trends, check our home value appreciation guide. ## How Accurate Are Online Home Value Estimates? Since most homeowners start with online estimators, it's worth understanding exactly how reliable they are. [Clever Real Estate's analysis](https://listwithclever.com/real-estate-blog/home-value-estimate-websites/) provides some of the clearest accuracy data available: | **Estimator** | **On-Market Median Error** | **Off-Market Median Error** | | Redfin | 2.09% | 6.47% | | Zillow | 2.4% | 7.49% | | Realtor.com | Undisclosed | Undisclosed | These percentages might sound small, but on real dollar amounts they add up quickly. On a **$400,000 home**, a 7.49% error means the estimate could be off by approximately **$30,000** in either direction. On a $600,000 home, you're looking at a potential $45,000 swing. Several factors make AVM accuracy worse: - **Rural locations** with fewer comparable sales - **Unique or custom homes** that don't match neighborhood patterns - **Recent renovations** not yet reflected in public records - **New construction** in areas without established pricing data - **Rapidly shifting markets** where conditions change faster than data updates The bottom line: online estimators are excellent for a quick, free starting point. They're not reliable enough to set a list price, negotiate a sale, or make major financial decisions. For that, you need a [professional evaluation](https://www.opendoor.com/articles/home-appraisal-guide-what-it-is-how-long-it-takes-what-to-expect) or at minimum a CMA from an experienced agent. To compare specific tools and their methodologies, see our detailed home value estimator comparison. ## Top Questions Homeowners Ask About Home Value ### How much can I sell my house for? The price you can sell your home for depends on what buyers in your local market are currently willing to pay — which is influenced by comparable recent sales, your home's condition, local demand, and broader economic factors like interest rates. The best way to answer this question is to combine at least two valuation methods: start with a free online estimate for a ballpark, then request a CMA from a local agent for a more refined figure. Keep in mind that your sale price and your *net proceeds* are two different numbers. After you account for [agent commissions](https://www.opendoor.com/articles/who-pays-real-estate-agent-commission), closing costs, and any repairs, you'll take home less than the headline price. Use a [seller net sheet](https://www.opendoor.com/articles/sellers-whats-your-bottom-line-the-seller-net-sheet-explained) to calculate what you'll actually walk away with. ### Will renovating my house increase its value? It can — but the return on investment varies dramatically by project type. According to [industry research on home improvement value](https://www.bobvila.com/articles/home-improvement-value/), minor kitchen updates and bathroom refreshes tend to deliver stronger returns than major overhauls. Highly personalized projects — like a luxury home theater or a pool in a climate where pools aren't the norm — often add far less value than they cost. That said, ROI varies meaningfully by region, property type, and buyer preferences, so what holds in one market may not apply in another. The key question isn't "will this renovation increase my home's value?" but rather "will it increase my home's value by *more than it costs*?" For guidance on where to focus your budget, check our guide to the [best home improvements to increase value](https://www.opendoor.com/articles/best-home-improvements-to-increase-value). ### Is it worth renovating before selling? Sometimes. Strategic, cost-effective updates — fresh paint, updated fixtures, minor kitchen and bathroom refreshes — can help your home show better and attract stronger offers. Major renovations, however, rarely make financial sense right before a sale because you're unlikely to recoup the full cost. Focus on [improvements that increase curb appeal and eliminate deal-breakers](https://www.opendoor.com/articles/should-you-make-home-improvements-before-listing) rather than complete overhauls. ### How do online home value estimators work? Automated Valuation Models (AVMs) use algorithms that analyze publicly available data — including tax records, recorded sale prices, active and recently sold MLS listings, and neighborhood trends — to calculate an estimated market value. [Redfin states it uses more than 500 data points](https://www.redfin.com/what-is-my-home-worth) about a home, its market, and its neighborhood to generate its estimate. These tools update regularly as new data becomes available, but they can't account for interior condition, recent upgrades, or unique property features. ### What's the difference between market value, appraised value, and assessed value? Market value is what a buyer would pay in today's market. Appraised value is a licensed professional's certified opinion of worth. Assessed value is the figure your county uses to calculate property taxes. These three numbers can — and usually do — differ from one another. For most homeowners considering a sale, [fair market value](https://www.opendoor.com/articles/fair-market-value-of-a-home-what-it-means-and-how-to-find-it) is the number that matters most. ### Are iBuyer offers a good indicator of my home's value? They're a useful data point, but they represent a floor — not market value. iBuyers offer convenience and speed, which comes at a price: their offers factor in service fees, estimated repairs, and profit margin. Think of an iBuyer offer as the minimum you could expect to receive, then compare it against a CMA or appraisal to understand the full picture. ### How often should I check my home's value? If you're not planning to sell or refinance, an annual check is sufficient — just enough to stay informed about your equity position. If you're actively considering a sale, check monthly in the lead-up and get a formal CMA or appraisal before listing. Markets can shift quickly, especially in periods of [changing interest rates](https://www.opendoor.com/articles/us-housing-market-shows-cooling-trend). ### Can I check what any home is worth, or just my own? You can check the estimated value of virtually any residential property using free online tools or public records. This is useful if you're a buyer researching a potential purchase, or a homeowner checking what neighbors' homes are selling for. Our guide to looking up any home's value by address walks through the best free methods. ### Do solar panels, pools, or new roofs increase home value? Each of these improvements *can* add value, but the amount varies by location, market demand, and buyer preferences. We've done deep dives on [whether solar panels increase home value](https://www.opendoor.com/articles/do-solar-panels-increase-home-value), [whether pools add value](https://www.opendoor.com/articles/does-a-pool-add-value-to-your-home-what-the-data-actually-shows), and [what a new roof does for resale](https://www.opendoor.com/articles/does-a-new-roof-increase-home-value) — each with data on what buyers actually pay more for. ## The Best Approach: Combine Multiple Methods No single valuation method is perfect. Each one has blind spots. The smart move is to layer multiple approaches: 1. **Start with two or three free online estimates** to establish a broad range. 2. **Request a CMA from a local agent** to refine that range with professional insight. 3. **Run your own comp analysis** to gut-check the numbers. 4. **If the stakes are high** — a sale, refinance, divorce, or estate settlement — **hire an appraiser** for a certified valuation. This layered approach gives you both the convenience of quick estimates and the accuracy of expert analysis. And it protects you from the single biggest mistake homeowners make: relying on one number from one source and treating it as gospel. Your home is too valuable — both financially and personally — for guesswork. Take the time to triangulate, and you'll make better decisions no matter what comes next. Whether you're ready to [sell](https://www.opendoor.com/articles/how-to-sell-your-house-fast-complete-guide) or simply want to understand your financial position, knowing your home's true value puts you in control. [Get your offer](#) ## Frequently Asked Questions ### How much is my house worth right now? Your home's current value depends on local market conditions, recent comparable sales, and your property's specific condition. Start with a free online estimator for a ballpark, then request a CMA from a local agent for a more accurate figure. ### What is the most accurate way to determine home value? A professional appraisal is generally the most reliable method, combining physical inspection with comparable sales analysis and certified professional judgment. Fees commonly fall in the $300–$600 range for a standard single-family home. ### Are Zillow and Redfin estimates accurate? They're reasonable starting points but not definitive. Median error rates range from about 2–2.5% for on-market homes to [6.5–7.5% for off-market homes](https://listwithclever.com/real-estate-blog/home-value-estimate-websites/), which can mean tens of thousands of dollars on a typical property. ### How do I get a free home valuation? You can use online estimators, request a free CMA from a local real estate agent, or use the FHFA House Price Index Calculator — all at no cost. ### What is a comparative market analysis (CMA)? A CMA is a report prepared by a real estate agent that analyzes recent comparable sales, active listings, and expired listings to estimate your home's market value. It's typically offered for free. ### What is the difference between assessed value and market value? Assessed value is set by your county for property tax purposes and often lags behind actual market conditions. Market value is what a buyer would pay today — it can diverge significantly from the assessed figure, in either direction, depending on your market and how recently assessments were updated. ### How do iBuyer offers compare to market value? iBuyer offers typically come in below full market value because they factor in service fees, repair estimates, and profit margins. They offer speed and convenience in exchange for a lower net price. ### Can I determine my home's value without an appraiser? Yes. Free online estimators, CMAs from agents, DIY comp analysis, and the FHFA calculator all provide estimates without an appraiser. However, for major financial decisions, a professional appraisal remains the most reliable option. ### How much does a home appraisal cost? Fees for a standard single-family home appraisal commonly fall in the $300–$600 range, though costs vary by location, property size, and complexity. ### Do renovations always increase home value? No. Some renovations — like [minor kitchen remodels](https://www.bobvila.com/articles/home-improvement-value/) — offer strong ROI, while others may not recoup their cost. The return depends on the project type, your local market, and buyer preferences. ### Why do different websites show different values for my home? Each platform uses different data sources, algorithms, and update frequencies. Differences of 5–10% between estimators are common, which is why experts recommend checking multiple sources and averaging the results. ### How often do online home value estimates update? Update frequency varies by platform — some refresh more often than others as new sales data becomes available. None will immediately reflect recent renovations, interior condition changes, or other property-specific updates. ### What should I do if I think my home's assessed value is wrong? You can formally contest your property tax assessment through your county assessor's office. Having a recent appraisal or CMA that shows a different value strengthens your case significantly. ### Is it worth getting multiple CMAs from different agents? Yes. Requesting CMAs from two to three agents gives you a range of opinions and helps you identify which agent knows your market best — especially valuable if you're planning to list. --- *Originally published at [https://www.opendoor.com/articles/how-much-is-my-house-worth-7-ways-to-find-out-your-homes-value](https://www.opendoor.com/articles/how-much-is-my-house-worth-7-ways-to-find-out-your-homes-value)*
