If you're preparing to sell your home, understanding the difference between assessed value and market value helps you set realistic expectations, read your paperwork with confidence, and spot a strong offer when it arrives. This walkthrough is for homeowners across Atlanta, Dallas, Tampa, Orlando, and every market we serve who want to know exactly what their home is worth before they list it. At Mark Spain Real Estate, our team has nearly 30 years of experience and more than $20 billion in real estate sold, and we walk sellers through this exact question every day.
Here's the short version: assessed value is a number your local government uses to calculate property taxes. Market value is what a real buyer will actually pay for your home today. They can differ by tens of thousands of dollars on the same house, and that's completely normal.
The confusion is understandable. Both numbers describe "what your home is worth," and both show up in official-looking documents. But they're calculated by different people, for different reasons, on different schedules. Once you understand how each one works, you'll know which number to ignore when you're pricing your home and which one to pay attention to.
This guide is for you if:
If any of those sound like you, keep reading. We'll break down both numbers, show you a simple workflow for finding your home's real market value, and explain what to do with the answer.
Here's the process we recommend to every seller, step by step.
Assessed value comes from your county or municipal tax assessor. Its only job is to give local government a basis for calculating your property taxes. Assessors typically use mass-appraisal techniques: they look at your home's basic characteristics (size, age, lot) plus broad sales data from your area, often on a set schedule that can lag the market by a year or more.
Many jurisdictions also apply an assessment ratio, so your assessed value might be a percentage of an estimated market value rather than the full figure. That's one reason the number on your tax notice can look surprisingly low. The key takeaway: assessed value is built for tax purposes, not for pricing a sale.
Market value is the price a willing buyer and a willing seller would agree on in today's market. It's driven by live conditions: recent comparable sales, buyer demand, your home's condition and updates, seasonality, and how your home shows compared to the competition. Unlike an assessment, market value changes constantly. A great spring selling season, a new kitchen, or a new employer moving into town can all push it up.
This is the number that matters when you sell. Your listing price, your offers, and your final sale price all live in the market-value world.
Online estimate tools are a fine starting point, but they can't see your updated kitchen, your finished basement, or the fact that the comp two streets over backed onto a busy road. The most accurate way to find your home's market value is a Comparative Market Analysis (CMA), where a local agent studies recent sales of homes like yours and prices your home against real, current conditions.
At Mark Spain Real Estate, we conduct a CMA as a standard part of our listing process, and we'll walk you through the numbers in plain language. You can start the conversation with our team and get a clear picture of what your home would sell for today.
Once you know your market value, you can choose the selling path that fits your life. A full market listing puts your home in front of the broadest possible pool of buyers and is built to maximize your price through exposure. If speed and certainty matter more, our Guaranteed Cash Offer program gives eligible sellers a cash offer with no repairs, no showings, and a closing date you pick. Neither path is better across the board; the right one depends on your timeline, your home, and your goals.
With a professional market value in hand, you price your home against real comps, not against your tax assessment. From there it's preparation, marketing, showings, and negotiation, with your agent team handling the details. When an offer comes in, you'll be able to judge it against a number you actually trust.
Here's what changes when you understand the difference between these two numbers:
The biggest outcome is peace of mind. Selling a home is one of the biggest financial decisions you'll make, and knowing which number to trust removes a whole layer of stress from it.
Why is my assessed value so much lower than what homes are selling for? Assessors use mass-appraisal methods on a set schedule, and many jurisdictions apply an assessment ratio that reduces the taxable figure. The result often trails the live market. It's a tax tool, not a price estimate.
Can my home's market value be lower than its assessed value? Yes. If the market cools after an assessment cycle, or if your home needs repairs the assessor didn't account for, market value can come in below the assessed figure. The two numbers move on different clocks.
Do I need to know my assessed value when I sell? It's good to have for context, especially if you're estimating your proceeds and want to think through costs you've been carrying. But your listing price should be built from current comparable sales and your home's condition, not from the tax roll. For questions about taxes on a sale, talk to a CPA or tax professional.
How do I find my home's true market value? Start with a professional Comparative Market Analysis from a local agent who knows your neighborhood. You can also explore our selling options to see which path fits your goals, then get a real number based on your actual home.
Assessed value tells your county how to calculate your taxes. Market value tells you what a buyer will pay. When you're ready to sell, only one of those numbers should shape your strategy, and getting it right starts with a real market analysis of your specific home.
