Your house sale profit is your sale price minus your remaining mortgage payoff, closing costs, any applicable commissions and any capital gains tax owed. Looking only at the sale price can leave you overestimating what you keep. You can compare our Fast Cash Offer, where we buy your house as-is and close, with our Premium Cash Offer, where a pre-approved FHA or conventional buyer we already have, ready to go, pays more and buys directly from you. You choose. Compare what you keep after deductions with either offer.

Factor	Traditional Route	Cash Flow Deals
Repair costs before sale	Often paid out of pocket to raise sale price	No repair spend required, sold as-is
Commission costs	Typical listing agent commission applies	No traditional listing commission
Time-based holding costs	Mortgage, taxes, insurance continue while listed	Set closing date limits extra holding time

The Basic Formula

Start with the accepted sale price. Subtract the payoff balance on your mortgage, not your original loan amount, the current remaining balance plus any accrued interest. Subtract closing costs, which commonly include title fees, transfer taxes, and prorated property taxes. Subtract agent commissions if you're using a listing agent. What's left is your net proceeds before tax.

Where Sellers Miscalculate Most Often

The most common mistake is using the original purchase price paid off years ago instead of the current mortgage payoff, which includes any home equity loans, lines of credit, or refinances taken out since. A seller can be surprised at closing by how much smaller the payoff-adjusted number is than they expected.

Capital Gains Tax On The Sale

Profit above your cost basis, roughly what you paid plus qualifying improvements, can be subject to capital gains tax. Federal law allows an exclusion of a set amount of gain on a primary residence if ownership and use requirements are met, which shields most typical sellers from owing tax on the sale.

Costs That Reduce Taxable Gain

Documented capital improvements, a new roof, an addition, a major system replacement, add to your cost basis and reduce your taxable gain. Routine repairs and maintenance generally don't count. Keeping receipts for major work pays off directly at tax time.

Selling As-Is Versus Investing In Repairs First

Repairs before selling can raise your sale price, but paying cash up front and adding weeks can reduce your profit. Weigh the repair cost and added time against the price lift the work actually produces; every dollar spent does not necessarily add a dollar or more to your final price. With our Fast Cash Offer, we buy your house as-is and close, with no repairs for you to make. With our Premium Cash Offer, a pre-approved FHA or conventional buyer we already have, ready to go, pays more and buys directly from you. You choose. On Premium, only what the buyer's lender requires gets fixed. We cover repair costs, and we figure out a way, so nothing comes out of your pocket: the work is funded up front and settled from the sale proceeds, from our share. For either offer, the number is agreed before any work starts, and it changes only if you agree. The one exception: if something structural surfaces that was not visible or disclosed before we signed — foundation issues, hidden moisture, old wiring, cast-iron drain failure — we re-cost it and bring the number back to you. You decide. You can walk away. We disclose what we know at offer time so this almost never happens. If the Premium buyer's loan falls through, that is our problem, not yours, and you can still take the Fast Cash Offer at its own number, with the Premium Cash Offer alongside it for comparison.

Common questions

Is house sale profit the same as sale price?

No. Profit is what's left after subtracting your mortgage payoff, closing costs, agent commissions if applicable, and any tax owed, not the raw sale price.

Do I have to pay capital gains tax on selling my house?

Many sellers don't, thanks to a federal exclusion on gain from a primary residence, as long as ownership and use requirements are met. Check current IRS rules for your situation.

What counts as a capital improvement that reduces my tax bill?

Generally, permanent upgrades like a new roof, an addition, or a major system replacement, not routine repairs or maintenance.

How much are typical closing costs for a seller?

They vary by location and deal terms, but commonly include title fees, transfer taxes, and prorated property taxes, on top of any agent commission.

Does selling as-is lower my profit?

Not necessarily. It can raise your net profit once you subtract what repairs and holding costs would have cost, even if the headline sale price is lower.

What this means for your options

A value estimate is a starting point, not a guaranteed number.

Wait and see

Keep the property as-is and hope conditions improve. The mortgage, insurance, and upkeep keep costing money while you wait, with no set date for things to turn around.

List with a traditional agent

Standard MLS listing, typically 5-6% in commission, and a financed buyer whose deal depends on appraisal, inspection, and lender approval — any of which can fall through after weeks on market.
