# Home Value: The Complete Guide to What Your Home Is Worth By Opendoor Editorial Team | 2026-04-14 Your **home value** is one of the most important numbers in your financial life — yet most homeowners only check it when they're about to sell. Understanding what your home is worth, how that number is calculated, and what moves it up or down can help you make smarter decisions whether you're selling, refinancing, tapping equity, or simply tracking your net worth. This guide covers everything: the three types of home value, how they're determined, how to find yours for free, what factors move the needle most, and how today's market conditions affect your number. ## What Is Home Value? Home value is a broad term that gets used in several different ways, and those differences matter. Depending on who's calculating your home's worth and why, you may see three distinct numbers: ### 1. Market Value **Market value** is what a willing buyer would pay a willing seller for your home in an open, competitive market — with neither side under pressure to act. This is the number that matters most when you're thinking about selling or buying. Market value is not a fixed fact; it's an estimate based on current conditions. Two appraisers looking at the same home can come up with different market values. And the same home might command different prices in a hot seller's market versus a slow buyer's market. ### 2. Appraised Value **Appraised value** is a formal, professional estimate of market value produced by a licensed appraiser. Lenders require appraisals before approving most mortgages and refinances to ensure they aren't lending more than the property is actually worth. Appraised value should be close to market value, but it's not always identical. If an appraisal comes in lower than the agreed purchase price, the deal can fall apart or require renegotiation. ### 3. Assessed Value **Assessed value** is the number your local government uses to calculate your property tax bill. It is set by a municipal assessor and is often significantly lower than market value — some jurisdictions assess properties at 80%, 60%, or even lower percentages of market value. Assessment schedules vary widely: some counties reassess every year, others every three to five years. When people ask "what is my home worth," they almost always mean market value. Assessed value and appraised value serve specific, narrower purposes. **Why it matters: **If your assessed value seems high relative to market value, you may be overpaying on property taxes — and you have the right to appeal. ## How Is Home Value Determined? Whether you're using an online estimator, getting a CMA from an agent, or going through a formal appraisal, home value is driven by the same core inputs. ### 1. Location Location is the single most powerful driver of home value. This includes: - Neighborhood desirability — proximity to employment centers, walkability, safety statistics - School district quality — homes in top-rated school districts routinely command 5–10% premiums - Access to amenities — parks, transit, grocery stores, restaurants - Proximity to negatives — busy roads, industrial sites, flight paths, floodplains depress values Location is the one factor you genuinely cannot change, which is why it dominates every valuation model. ### 2. Size and Condition Larger homes generally sell for more, but price-per-square-foot is what really matters in comparisons. A 2,000-square-foot home in move-in condition will outperform a 2,400-square-foot home with a dated kitchen and a leaky roof. Key condition factors that appraisers and buyers weigh: - Age and condition of roof, HVAC, plumbing, and electrical systems - Kitchen and bathroom finishes - Overall maintenance and cleanliness - Functional layout (an awkward floor plan reduces value even in good condition) ### 3. Comparable Sales (Comps) "Comps" — recently sold homes that are similar to yours in size, age, condition, and location — are the bedrock of any home valuation. The standard practice is to look at sales within roughly 1 mile that closed within the last 6 months. The key variables compared: - Square footage - Bedroom and bathroom count - Lot size - Year built - Condition and upgrades - Sale date (older sales are adjusted for market movement) Appraisers make dollar adjustments when a comp differs from the subject property — adding value if the comp had fewer bedrooms, subtracting value if the comp was in better condition, for example. ### 4. Market Conditions Even two identical homes sold six months apart can yield very different prices depending on supply and demand. Rising mortgage rates, falling inventory, or local economic disruptions can shift values significantly over short periods. ## How to Find Out What Your Home Is Worth There are three main approaches, ranging from quick and free to rigorous and paid. Each serves a different purpose. ### Method 1: Online Automated Valuation Models (AVMs) AVM tools like the ones offered by Zillow (Zestimate), Redfin, Chase, and Opendoor use algorithms to estimate value based on public records data, tax assessments, and recent sales. They can give you an instant ballpark figure at no cost. **Pros: **Fast, free, requires no contact with anyone **Cons: **Can be off by 5–10% or more, especially for unique properties, recently renovated homes, or properties in areas with few comparable sales AVMs are best used as a starting point, not a final answer. **Opendoor's home value estimator** gives you a free, instant estimate based on your specific address — and unlike many generic AVM tools, it draws on Opendoor's proprietary transaction data from markets across the country.

Agents have access to more transaction data than public AVMs and can apply local expertise that algorithms miss. CMAs are typically offered for free by agents as part of a listing conversation. If you're thinking about selling in the next 6–12 months, getting a CMA is a smart move even before you're ready to list. **Pros: **More accurate than AVMs for unique or hard-to-comp properties, free, includes human judgment **Cons: **Requires sharing your contact info and engaging with an agent, quality varies ### Method 3: Formal Home Appraisal A licensed appraiser conducts an in-person inspection, documents the home's condition and features, pulls their own comps, and produces a written appraisal report. Appraisals are required by lenders for mortgages and refinances but can also be ordered independently. **Pros: **Most accurate method, lender-accepted, defensible in disputes **Cons: **Costs $300–$700 on average, takes time (typically 1–2 weeks), overkill if you just want a rough estimate **Which method should you use? **For a quick sense of how much your house is worth now, start with an online estimator. For serious decisions — pricing your home to sell, refinancing, estate planning — get a CMA or formal appraisal. ## What Affects Home Value the Most? Here's a rough ranking of value drivers, from most to least impactful, based on how appraisers weight them and what buyer behavior tells us: | Rank | Factor | Notes | | --- | --- | --- | | 1 | Location / neighborhood | School district, safety, desirability — biggest driver, can't be changed | | 2 | Size (square footage) | Price per square foot is the standard unit of comparison | | 3 | Condition and age of systems | Roof, HVAC, plumbing, electrical — deferred maintenance destroys value | | 4 | Kitchen and bathrooms | Most scrutinized rooms; outdated finishes cost dollars at the offer table | | 5 | Curb appeal and first impression | Buyers decide within seconds; low-cost but high-impact | | 6 | Market timing | Seller's vs. buyer's market can swing value 10–20% | | 7 | Specific upgrades | Not all renovations return their cost — some add more than they cost, most don't | Location, size, and condition together account for the majority of your home's value. Upgrades matter, but they operate at the margin — you can't out-renovate a bad location.

A $50,000 kitchen remodel in a $250,000 neighborhood will not add $50,000 to your price. The same remodel in a $750,000 neighborhood might come close.

Here's a clear breakdown of when each one matters: ### When Each Number Matters **Market value matters when:** - Pricing your home to sell - Making an offer on a home to buy - Estimating equity in your property - Tracking your net worth **Appraised value matters when:** - Getting a mortgage or refinancing - PMI removal (you generally need the appraisal to show 20%+ equity) - Estate settlements and probate - Divorce proceedings with shared property **Assessed value matters when:** - Paying property taxes - Appealing your tax bill - Calculating tax-related deductions ### The Gap Between Assessed and Market Value The ratio of assessed value to market value is called the **assessment ratio**. In some states and counties, it's close to 100% — what you'd pay in property taxes is based on full market value. In others, homes are assessed at 50–80% of market value by design. If you believe your assessed value is too high relative to current market conditions, you have the right to appeal with your county assessor's office. Supporting your appeal with recent comps (similar to what a CMA provides) is usually required. ## How Market Conditions Affect Home Values The same home can be worth dramatically different amounts depending on when and where it's sold. Market conditions are one of the most underappreciated factors in home value. ### Interest Rates and Affordability Mortgage rates have a direct, mechanical relationship with home values. When rates rise, monthly payments on any given purchase price go up — which compresses what buyers can afford, which puts downward pressure on prices. When rates fall, the reverse happens. As a rough rule of thumb: a 1-percentage-point increase in mortgage rates reduces buying power by roughly 10–11%. This doesn't always translate 1:1 into price declines (sellers resist cutting prices), but it does slow appreciation and increase time on market. ### Supply and Demand (Inventory) The fundamental driver of any market is the balance between listings available and buyers actively searching. When supply is tight and demand is strong, multiple-offer situations develop and homes sell above list price. When supply is abundant and demand is weak, buyers gain leverage and prices soften. **Key inventory signal to watch: **Months of supply. Fewer than 3 months of supply is considered a strong seller's market. More than 6 months is a buyer's market. The national average has hovered near 4 months heading into 2026. ### Local Economic Conditions Local job market strength, migration patterns, and development activity shape values at the neighborhood and city level. Markets with strong employment growth (tech hubs, logistics corridors, healthcare expansion) tend to see consistent appreciation. Markets losing jobs or population face sustained headwinds even when national conditions are strong. ### Seasonality Home values tend to peak in spring and early summer, when the largest number of buyers enter the market. Listing in February through June has historically generated higher offers than listing in fall or winter — though the gap has narrowed in recent years as online search has reduced seasonality's influence. ## Frequently Asked Questions **How often does home value change?** Home values change continuously with market conditions — there is no fixed schedule. Online estimators like Zillow's Zestimate update frequently (sometimes weekly) as new sales data flows in. Your assessed value, however, changes only when your county reassesses, which varies from annually to every few years depending on jurisdiction. **Does renovation always increase home value?** No. Most renovations return only a fraction of their cost at resale. The 2025 Cost vs. Value Report from Remodeling Magazine shows that the average major remodel returns around 60–70 cents on the dollar. Minor cosmetic updates and maintenance-oriented projects tend to return more proportionally than expensive luxury remodels. **How accurate are Zillow Zestimates?** Zillow reports a median error rate of approximately 2–3% for on-market homes and 6–7% for off-market homes. In practice, accuracy varies significantly by market: areas with dense, frequent comparable sales tend to produce more accurate estimates. Rural properties, unique homes, and markets with limited public sales data can see much larger errors. Always treat an AVM as a starting point, not a definitive answer. **What is my home worth if I just want to know the estimate?** The fastest way to estimate house value is to use a free online AVM. Enter your address at opendoor.com/w/home-value for an instant estimate. For a more accurate picture, request a CMA from a local agent or order a formal appraisal. **How do I find out my house value without Zillow?** Several tools offer free estimates: Redfin, Realtor.com, Chase's home value estimator, Bank of America's home value center, and Opendoor all provide AVM-based estimates. Each uses slightly different data and algorithms, so checking two or three sources and averaging the results gives you a better sense of range. **How can I find out my house value for free?** Use a free AVM tool (Opendoor, Zillow, Redfin, Chase, Realtor.com), request a free CMA from a local real estate agent, or check your county assessor's website for your most recent assessed value. All three are free. Only a formal appraisal costs money. **Does location really matter that much?** Yes — it is consistently the number one determinant of home value across every academic study and practitioner guide. Buyers are ultimately buying access to a neighborhood, school district, commute time, and community — the house is the vehicle. Two identical homes in different locations can have values that differ by 50% or more. **How much does a home value increase per year on average?** Historically, U.S. home values have appreciated at roughly 3–5% per year on average — roughly in line with or slightly above inflation. However, averages mask enormous variation. Some markets appreciate 10–15% in a single year during supply-constrained booms; others go flat or negative during corrections. **How does school district affect home value?** School district quality is one of the most consistently cited value drivers in real estate research. Studies have found that moving from an average to a top-rated school district adds an average of 7–10% to home values, with some high-demand districts commanding premiums of 20%+. **What is the difference between home value and home equity?** Home value is what your home is worth on the market. Home equity is the portion you actually own — your home value minus what you still owe on your mortgage. If your home is worth $400,000 and you have a $250,000 mortgage balance, your equity is $150,000. Equity grows as your home appreciates and as you pay down your loan principal. ## The Bottom Line Home value is not a single number — it's a range of estimates shaped by location, condition, market conditions, and methodology. The most important things to understand: 1. Market value is what buyers will actually pay — the number that matters for selling decisions 2. Appraised value is a lender-required formal estimate — the number that gates financing 3. Assessed value is for tax purposes — often lower than market value and updated infrequently 4. The biggest drivers of value are location, size, and condition — in that order 5. Online estimators are a useful starting point, but CMAs and appraisals are more accurate for consequential decisions If you're wondering what your home is worth today — whether you're thinking about selling, refinancing, or just want to know — the fastest, easiest first step is a free Opendoor estimate.
