How Much Equity Do You Have? How to Calculate Home Equity Before You Sell in Palm Beach County

Knowing how to calculate home equity is the first step for any owner who is thinking about selling. Equity is simply the part of the home you own outright. It is the market value minus every loan tied to the property. But the number you see on paper is not the same as the check you get at closing. This guide shows Palm Beach County owners how to estimate value from recent sales, subtract the payoff, take out selling costs, and see the gap between gross equity and net proceeds.

Key takeaways

• Gross equity is market value minus all loans on the home, including any HELOC or second mortgage.
• Net proceeds are what you keep after the payoff and the cost of selling, so they are always lower than gross equity.
• Value comes from recent comparable sales, not from your tax bill or a single online estimate.
• Florida charges documentary stamp tax on deeds at 70 cents per $100 of the price in every county except Miami-Dade.
• In August 2026 the Palm Beach County single-family median was $650,000, and the condo and townhouse median was $300,000.

Why sellers need to know how to calculate home equity

Lenders and homeowners use the word equity in a few ways. For a seller, the useful version is short. Equity equals what a buyer would pay today, minus what you owe on every loan secured by the home.

For example, say a home would sell for $600,000 and the mortgage payoff is $250,000. In that case, the gross equity is $350,000. That figure tells you how much of the home you own. However, it does not yet tell you what you will walk away with, because selling costs money.

So most sellers need two numbers. First comes gross equity. Second comes net proceeds, which is gross equity minus the cost of the sale. This guide walks through both.

How to calculate home equity in three steps

The math itself is simple. Getting good inputs is the hard part. Here is the basic formula most agents use.

1. Estimate today's market value from recent comparable sales.
2. Subtract the payoff on your first mortgage, plus any second mortgage, HELOC or other lien.
3. Subtract your expected selling costs to see your likely net proceeds.

Each step has its own traps. Below, we cover what to look for in each one.

Step 1: Estimate value from comparable sales

Your home is worth what a ready buyer will pay for it right now. The best evidence is a set of recent sales of similar homes nearby. Agents call these comps.

Good comps share a few traits. They sold recently, ideally in the last three to six months. Most are close by, often in the same subdivision or condo building. They also match your home in size, age, lot, view and condition. A pool home on a lake is not a good comp for an interior lot with no pool.

You can look up sales yourself. The Palm Beach County Property Appraiser lets anyone search recorded sales and property records by address or area. Keep in mind that recorded sales lag the market by weeks. Also, the price alone does not show condition, seller credits or whether a sale was between family members.

Online estimates are a fine starting point. Still, they can miss updates, water views and other local details. Our guide to getting a comparative market analysis explains how an agent builds a pricing range from comps.

Why your tax value is not your market value

Many Florida owners look at the just value or assessed value on their tax notice. That is a mistake when you are pricing a sale. If you have a homestead, Save Our Homes caps how fast your assessed value can rise each year. As a result, long-time owners often have an assessed value far below what the home would sell for. The just value is closer to market, but it is set as of January 1 and is still not a sales price.

Step 2: Get your real loan payoff

Next, find out what you owe. Your monthly statement shows a principal balance, but the payoff is usually higher. That is because interest accrues daily and the lender adds it through the payoff date. Some loans also carry fees.

For a closer number, ask your servicer for a payoff statement. Federal rules require the servicer to send an accurate payoff statement within seven business days of a written request in most cases. When you sell, the title company orders this for you.

Also count every lien. A HELOC, a second mortgage, a solar loan recorded against the home, an unpaid assessment or a judgment lien all come out of the sale. If you are not sure what is recorded, our post on selling a house with a lien explains how title searches find them.

Step 3: Subtract selling costs

Then take out the cost of selling. The biggest items for most Florida sellers include these:

• Real estate commissions, which are negotiable and set in your listing agreement.
• Florida documentary stamp tax on the deed. The Florida Department of Revenue sets the rate at 70 cents per $100 of the price outside Miami-Dade. On a $600,000 sale, that is $4,200.
• The owner's title insurance policy, which the seller often pays for in Palm Beach County.
• Prorated property taxes, which in Florida are paid in arrears.
• Any credits, repairs or concessions you agree to after the inspection.
• HOA or condo estoppel fees, if you have an association.

Our post on how much it costs to sell a house covers each line item in more detail.

How to calculate home equity and net proceeds: a worked example

Here is a simple example with round numbers. It is only an illustration, not a quote for your home.

• Estimated sale price from comps: $600,000
• First mortgage payoff: $240,000
• HELOC payoff: $20,000
• Gross equity: $600,000 minus $260,000, or $340,000

Now subtract selling costs. Say commissions, doc stamps of $4,200, title, prorated taxes and a small repair credit add up to $45,000. In that case, the net proceeds would be about $295,000 before any income tax on the gain.

So the owner owns $340,000 of the home on paper, but would walk away with roughly $295,000. That $45,000 gap is why we always show sellers both figures. A free home value report is a good way to check the first line of the math.

How appreciation and paydown built your equity

Equity grows in two ways. First, you pay down principal with each mortgage payment. Second, the market value of the home can rise over time.

Early in a 30-year loan, most of each payment goes to interest. As a result, paydown builds equity slowly in the first years and faster later on. Extra principal payments speed it up.

Appreciation depends on when you bought. Many South Florida owners who bought before 2020 have seen big gains in value since then. In contrast, owners who bought near a local peak may have less equity than they expect, especially in some condo segments. Your purchase year and price matter as much as today's market.

Single-family homes and condos are moving differently

The August 2026 report from Miami Realtors and the Beaches MLS shows a split in Palm Beach County. Single-family homes had a median price of $650,000 and went under contract in a median of 40 days, with 3.5 months of supply. Condos and townhouses had a median of $300,000, took a median of 69 days, and had 6.7 months of supply.

For a house owner, that points to steady demand. For a condo owner, it means more listings to compete with, so a careful price matters more. Condo sellers should also count any special assessment that the board has approved, since buyers will ask about it.

How to calculate home equity in Boynton Beach, Royal Palm Beach and Greenacres

The formula is the same everywhere, but the comps change from town to town. In Boynton Beach, an owner may be comparing a single-family home east of I-95 with one in a newer western community, and those are very different markets. Many condo and 55+ communities there also have their own price patterns.

In Royal Palm Beach and Greenacres, much of the housing is single-family homes in planned neighborhoods. As a result, comps from your own subdivision tend to be the most reliable. Lot size, a pool, a newer roof and updated impact windows can all move the number. Our Royal Palm Beach and Greenacres pages cover local housing in more depth.

Common mistakes in how sellers calculate home equity

Most errors come from using the wrong inputs. Watch out for these:

• Using a list price instead of a sold price as a comp.
• Counting your principal balance instead of the payoff.
• Forgetting a HELOC that shows a zero balance but is still open and recorded.
• Leaving out selling costs or prorated taxes.
• Pricing a home based on the most expensive sale in the area.

Also, do not assume past gains will repeat. Price from today's sales, not from where the market was two years ago.

Taxes on the gain are a separate question

Equity and taxable gain are not the same thing. Gain is based on your sale price minus your cost basis, not your loan balance. Under IRS Publication 523, many owners can exclude up to $250,000 of gain on a main home, or $500,000 for married couples filing jointly, if they meet the ownership and use tests.

Investors and second-home owners face different rules. Our guide to taxes when you sell a house in Florida covers the basics, and a CPA can run your own numbers.

Frequently asked questions

What is the simplest way to estimate my equity?

Take a realistic sale price based on recent nearby sales. Then subtract the payoff on every loan secured by the home. That gives you gross equity. Subtract selling costs to estimate what you would keep.

How accurate is Zillow when I calculate home equity?

It is a starting point only. Automated estimates can miss condition, upgrades and views. A comparative market analysis from a local agent, based on recent sold comps, is usually closer.

Does a HELOC with a zero balance affect my equity?

A zero balance does not reduce your equity. However, the line is still a recorded lien. At closing, the title company will need a payoff letter and a request to close the line so it can be released.

Why are my net proceeds lower than my equity?

Because selling has costs. Commissions, Florida doc stamps, title fees, prorated taxes and any credits to the buyer all come out of your gross equity at closing.

How often should I calculate my home equity?

Check it whenever you are making a big decision, such as selling, refinancing or opening a line of credit. In a shifting market, a value that is six months old can already be out of date.
