If your house is paid off, the equity you have is the home’s current fair market value minus any liens still attached to the title. With no mortgage balance, that usually puts your equity at or near 100 percent of what the home would sell for today. The exact figure comes down to two things: what a buyer would actually pay right now, and whether any other claims — unpaid property taxes, an IRS lien, a contractor’s bill, HOA dues — are sitting on your property records.
The Formula
Equity on a paid-off home is simple arithmetic:
Equity = Current Fair Market Value − Outstanding Liens
If the home would sell today for $450,000 and nothing is recorded against it, your equity is $450,000. If you owe $3,000 in back property taxes, your equity is $447,000. The number you plug in is always today’s market value, not the price you paid years ago. A house bought for $200,000 that would now sell for $450,000 gives you equity based on $450,000, because equity is what you could walk away with after a sale.
Figuring Out What Your Home Is Actually Worth
Current market value is the big variable, and there are three common ways to pin it down, each at a different level of precision.
- A professional appraisal is the most reliable. A licensed appraiser walks the property inside and out and compares it against similar homes that recently sold nearby. Appraisals typically run $300 to $600 depending on region and property type, and this is the figure a lender will insist on before approving any equity-based loan.
- A comparative market analysis from a real estate agent uses local sales data, active listings, and market trends. It’s less formal than an appraisal, agents often prepare one at no charge, and it’s enough for a solid ballpark.
- Automated valuation models on real estate websites generate an instant estimate from public records. They’re convenient but shaky, especially for unusual properties or neighborhoods with few recent comparable sales.
For a working estimate, start with an automated figure, cross-check it against recent sales on your block, and treat the result as a range rather than a precise number. If you’re planning to borrow against the home or sell, pay for the appraisal.
Why Your Property Tax Assessment Is Not Your Equity
Many homeowners glance at the assessed value on their property tax bill and assume that’s what the home is worth. It usually isn’t. Local governments often set assessed values below full market value to keep tax bills predictable, and many jurisdictions cap how much the assessed value can rise in a single year even when the market is climbing fast. The assessed value tells you about your tax bill. Fair market value tells you about your equity. Lenders refinance and underwrite home equity loans on market value, never on the assessor’s number.
Liens That Shrink the Number
Paying off the mortgage removes one lien. It does not guarantee the title is clean. A few other claims can quietly sit on your property and come out of your equity the moment you sell or try to borrow.
Property Tax Liens
Property taxes keep running regardless of mortgage status. Fall behind and the taxing authority records a lien that takes priority over nearly every other claim on the home, including older recorded mortgages and judgment liens. Left unpaid long enough, those taxes can force a sale even on a debt-free house.
Federal Tax Liens
Unpaid federal taxes attach to everything you own once the IRS has demanded payment and you haven’t paid.1Office of the Law Revision Counsel. 26 U.S. Code 6321 – Lien for Taxes Once the IRS files a Notice of Federal Tax Lien in the public record, it clouds your title and limits what you can do with the house until it’s resolved. The IRS does offer paths like subordination (allowing another lender to move ahead of the IRS lien so you can refinance) or discharge (removing the lien from a specific property), but you have to apply.2Internal Revenue Service. Understanding a Federal Tax Lien
Mechanic’s Liens and HOA Liens
If you hired a contractor and didn’t pay the full invoice, the contractor can file a mechanic’s lien in the county records. It has to be cleared before you can sell or refinance with clean title. Homeowners association dues and special assessments work similarly: unpaid amounts can become a lien, and in many states the HOA can eventually foreclose on it even when the home carries no mortgage.
Running a Title Search
A title search reviews public records to flag any liens, judgments, or other claims recorded against your property. It costs roughly $150 to $250 and is worth doing if you haven’t looked at your title since paying off the mortgage. It will surface old lines of credit that were never formally released, judgment liens from lawsuits, and recording errors that are quietly clouding your ownership. Only after that search comes back clean can you be confident the equity figure in your head matches the equity you actually have.
Loose Ends After Payoff That Can Erode the Number
Paying the final mortgage balance kicks off a few administrative steps. Ignore them and you can lose equity you thought was safe.
Confirm the Lien Release Got Recorded
Your lender has to file a satisfaction of mortgage (also called a release or discharge) in the county land records. Most states give them a defined window, typically 30 to 90 days after payoff. Until that document is recorded, the old mortgage still shows up on your title and will complicate any future sale or equity loan. If a few months pass and you haven’t seen confirmation, call the lender and check with the county recorder.
Pick Up Your Escrow Refund and Take Over the Bills
If your mortgage included escrow for property taxes and insurance, the servicer has to return any remaining balance to you within 20 business days of the final payoff.3Consumer Financial Protection Bureau. 12 CFR Part 1024 (Regulation X) – 1024.34 Timely Escrow Payments and Treatment of Escrow Account Balances Once the escrow closes, paying property taxes and insurance premiums is on you. Missing a tax installment because you forgot the lender is no longer handling it is one of the most common post-payoff mistakes, and it’s exactly how a clean title picks up a tax lien.
Keep Insurance in Place
No state requires homeowners insurance on a paid-off house. But dropping coverage means you absorb every dollar of damage, theft, or liability yourself. The home is probably your largest asset, and a burst pipe or a guest’s injury can run into tens of thousands. With no lender dictating coverage, this is also a reasonable moment to compare premiums.
A Note on Protection
Equity on paper isn’t the same as equity you get to keep in every situation. Bankruptcy law protects some of your home equity through a homestead exemption, with the amount varying widely by state and by whether you use the federal exemption.4Office of the Law Revision Counsel. 11 USC 522 – Exemptions Medicaid long-term care eligibility also counts home equity above a federal threshold that each state sets between $752,000 and $1,130,000 for 2026.5Department of Health and Human Services. 2026 SSI and Spousal Impoverishment Standards Neither changes the equity number itself, but both can affect how much of it survives a creditor claim or a nursing home stay. If either situation is on your horizon, the calculation above is the starting point, not the whole picture.
