These three financial terms describe your home's value in very different ways. Here's what each one means and why it matters to you as an owner.
Why Three Different Numbers Exist
Your home doesn't have a single fixed value — it has several, each calculated for a different purpose by a different party. Confusing these numbers is one of the most common financial mistakes homeowners make, and it can lead to poor decisions about borrowing, selling, or budgeting for taxes.
The three you'll encounter most often are equity, appreciation, and assessed value. None of them is the "true" value of your home — they're tools, each designed to answer a specific question. Understanding what each one measures, who calculates it, and when it matters puts you in a far stronger position as an owner.
Home Equity: What You Actually Own
Equity is the portion of your home's market value that you own outright — the difference between what the property could reasonably sell for today and what you still owe on it. If your home has a current market value of $350,000 and your remaining mortgage balance is $220,000, your equity is $130,000.
Equity builds in two ways: as you pay down your mortgage principal, and as your home's market value rises. It can also shrink — if property values fall and your loan balance stays high, equity erodes. Lenders care about equity when you apply for a home equity loan, a home equity line of credit (HELOC), or when refinancing. Most require you to retain at least 15–20% equity after borrowing.
Equity is also central to your personal net worth. For many American households, home equity represents their single largest asset. To explore how home ownership fits into your broader financial picture, see how net worth differs from income. And if you've heard claims about the fastest ways to build equity, it's worth reading what the research actually shows about equity-building strategies.
Equity Is Not the Same as Cash
Having significant equity does not mean you have immediate access to those funds. To convert equity into usable money, you typically need to sell the home, refinance your mortgage, or take out a secured loan product such as a HELOC. Each option involves costs, qualification requirements, and financial risk — including the possibility of losing the home if you cannot repay a secured loan.
Appreciation and Assessed Value: The Other Two Numbers
Appreciation refers to the increase in your home's market value over time, expressed either as a dollar amount or a percentage. If you paid $280,000 five years ago and comparable homes now sell for $350,000, your home has appreciated by $70,000 — or about 25%. Appreciation is driven by local market conditions, neighborhood development, interest rate cycles, and broader economic trends. It is not guaranteed, and it can reverse. Unlike equities or bonds, you cannot easily diversify a single property investment, so appreciation is best understood as a possibility rather than a promise.
Appreciation matters most when you're considering selling or refinancing, since market value is what a buyer will actually pay. If you're preparing to list, keep in mind that strategic updates can help — or hurt — your return. Our guide on preparing your home for sale without over-improving it explains how to think about pre-sale investments.
Assessed value is a figure assigned by your local government's assessor's office, used solely to calculate your property tax bill. It is typically a percentage of estimated market value — that percentage, called the assessment ratio, varies widely by jurisdiction. Assessed value is often lower than market value and can lag behind actual market changes by months or even years.
If your assessed value seems too high relative to what your home would actually sell for, you may have grounds to appeal. The property taxes explained guide walks through how assessments work and what the appeals process looks like.
Home Equity
The market value of your home minus what you still owe on your mortgage. It represents the share of the property you effectively own outright.
Appreciation
The increase in a property's market value over time. Appreciation is influenced by local market conditions, economic trends, and neighborhood factors, and is never guaranteed.
Assessed Value
A dollar figure assigned by a local government assessor, used exclusively to calculate property taxes. It is often lower than market value and may not reflect current selling prices.
Assessment Ratio
The percentage of a property's estimated market value used by a jurisdiction to set its assessed value. This ratio varies significantly by location.
HELOC
A Home Equity Line of Credit — a revolving credit line secured by your home's equity. Like a credit card, you draw and repay funds up to a set limit, typically over a defined draw period.
Market Value
The price a willing buyer would pay and a willing seller would accept for a property in an open, competitive market. This is distinct from both assessed value and appraised value.
