How to Estimate House Flipping Profit

Profit is what's left of the sale price after every cost of buying, fixing, holding, financing and selling. Holding and financing costs grow with each month the house sits, so time matters as much as the rehab budget.

Profit = sale price − purchase − buying costs − rehab − holding − interest − points − selling costs
Cash invested = purchase + buying costs + rehab − loan + points + holding + interest
70% rule: max purchase ≈ 70% × ARV − rehab

Interest here assumes an interest-only loan on the financed amount for the months held, as is typical for hard-money flip loans.

Tips

Budget a contingency (often 10% to 20%) for surprises behind walls. The 70% rule is a quick screening guideline used by many flippers, not a guarantee. Profits on flips held under a year are usually taxed as ordinary income; ask a tax professional.
