How Closing Costs Affect House-Flipping Profit

Two separate sets of closing costs

A flip has closing costs on both ends of the deal, and they behave differently:

• Purchase closing costs — title insurance, recording fees, lender fees, attorney fees — typically a smaller percentage of price, often in the 1-4% range depending on the market and how the deal is financed.
• Selling costs — agent commissions plus the seller's share of closing costs — typically the larger number, often 6-10% of the sale price (ARV), since real estate commissions alone are usually the biggest single line item in a flip's expense stack.

Why the purchase side gets underestimated

On a $180,000 purchase with $45,000 in repairs and a $290,000 ARV, moving purchase closing costs from a optimistic 2% ($3,600) to a more realistic 4% ($7,200) — the difference of a single additional point on lender fees or title costs — trims about $3,600 straight off the bottom line: projected profit drops from roughly $32,528 to $28,928. It's a small percentage of the deal, but a direct, dollar-for-dollar hit to profit, not something that gets absorbed elsewhere.

Why the selling side matters more

In this same example, selling costs at 6% of the $290,000 ARV run about $17,400 — nearly five times the purchase closing costs, and often the single largest expense category in the entire deal after the purchase price and rehab. It's calculated against ARV, not purchase price, so it scales with the property's final value, not what you paid for it.

Where flippers get this wrong

• Forgetting purchase-side closing costs entirely when doing quick mental math, especially on cash or hard-money deals where there's no traditional mortgage line item to remind you.
• Assuming a full commission discount that isn't actually available — some markets and agents negotiate lower commissions, but budgeting for a rate you haven't confirmed is optimistic planning, not a real number.
• Not re-checking selling costs against the final ARV once the rehab is done — if the property ends up appraising or selling higher than the original ARV estimate, selling costs go up proportionally too.

Both sides are already built into the House Flip Calculator's Purchase Closing Costs and Selling Costs fields — use your actual quoted rates rather than a generic assumption once you have real numbers from a title company and listing agent.
