You need enough equity to cover your mortgage payoff plus selling costs, which typically run 8 to 10 percent of your sale price once you add agent commission, title fees, transfer taxes, and prorated property taxes. If your sale price minus those costs still exceeds your loan balance, you close without bringing cash.
What actually gets subtracted from your sale price
Before you see a dime, your closing statement subtracts your remaining mortgage balance (your payoff, which includes accrued interest through the closing date), any other liens like a HELOC, tax lien, or judgment, listing agent commission, title insurance and closing fees, prorated property taxes and HOA dues, and any transfer taxes your state or county charges sellers. Add those up and you get your true breakeven number, not just your loan balance.
A rough example
Say you owe $310,000 on your mortgage and sell for $400,000. Commission and closing costs at roughly 9 percent eat about $36,000, and prorated taxes and small fees add another $2,000. That leaves you needing $348,000 from the sale just to zero out, which this example clears with $52,000 left over. If your payoff were $370,000 instead, you would be far closer to the line, and a lower-than-expected offer could push you into a shortfall.
How to find your real number before you list
Ask your lender for a payoff quote, not just your current balance, since it includes per-diem interest, then ask your agent for a net sheet: a document estimating your proceeds after commission, taxes, and typical closing costs at a realistic sale price. Comparing your payoff to that net sheet tells you exactly how much equity cushion you actually have.
What if you are close to the line or underwater
If your net sheet shows you would need to bring money to closing, you have options: negotiate a lower commission, ask the buyer to cover some closing costs, wait and build more equity through continued payments or appreciation, or in a true underwater situation, talk to your lender about a short sale. None of these require guessing, your agent and lender can model each scenario with real numbers.
Selling costs are not one flat number nationwide
The 8 to 10 percent range is a starting estimate, not a fixed rule, since commission is negotiable and varies by agent and market, and transfer taxes and recording fees differ significantly by state and even by county. A home in a state with a higher transfer tax could see closing costs closer to 11 or 12 percent, while a lower-cost state might land closer to 7 percent, so always confirm the specific figures for your area rather than relying on a national average.
Common mistakes that shrink your cushion
Sellers often underestimate their true payoff by checking their last mortgage statement instead of requesting an actual payoff quote, which includes extra per-diem interest and sometimes a small recording or reconveyance fee. Others forget prorated property taxes owed for the part of the year they still owned the home, which can add another few hundred to a couple thousand dollars depending on your local tax rate and closing date. Building in a small buffer, an extra 1 to 2 percent of sale price, protects you if the final numbers come in slightly different than your first estimate.
The Homexa position
Homexa® agents build a net sheet before you ever list a property, not after an offer comes in, so you know your realistic bottom line up front instead of finding out at the closing table.
Bottom line
Know your loan payoff and your estimated closing costs before you set an asking price. As a rule of thumb, if your equity is comfortably above 10 percent of your expected sale price, you likely will not need to bring cash to closing, but the only way to know for certain is to run your actual numbers.
