Fix-and-Flip Profit: Costs & Downside Cases

A flip's projected profit is the expected sale price minus every project cost. A large gap between purchase price and resale value is not enough: financing, the renovation timeline and the exit can consume that gap.

Working formulaPre-tax flip profit = sale proceeds − purchase − rehab − acquisition − financing − holding − selling costs

Hypothetical flip, before income taxes

Purchase
$150,000
Renovation
$40,000
Acquisition costs
$5,000
Financing costs
$6,000
Holding costs
$9,000
Selling costs
$18,000
Total project cost / sale price
$228,000 / $260,000

$32,000 base-case profit; $10,000 in the stated downside case.

Build an all-in cost estimate

Separate the purchase and renovation budget from acquisition charges, financing fees and interest, holding expenses, and selling costs. Use written quotes where possible. Avoid counting the same interest, insurance or closing item in two categories.

Holding costs can include taxes, insurance, utilities, maintenance and association charges. Selling costs may include brokerage compensation, transfer charges, settlement fees and negotiated buyer credits. Their amounts depend on the property, agreement and location.

Time changes the result

The base example projects $32,000 pre-tax profit on $228,000 total cost. If the sale price falls 5% to $247,000, rehab increases by $6,000 and the delay adds $3,000 of holding costs, profit falls to $10,000. This simplified downside keeps other costs fixed; percentage-based selling charges should be recalculated in a full model.

Profit on total project cost is different from return on your own cash. Borrowing changes cash invested and adds financing risk. Neither measure becomes an annual return unless you explicitly account for the project's duration and your chosen method.

Verify the exit before the purchase

Use comparable completed sales and a realistic project schedule to support the resale assumption. Asking prices alone do not prove the eventual selling price.

  • Check permits, scope, contractor bids and a contingency budget.
  • Model a slower sale and extra months of financing.
  • Review a hold-or-rent alternative without assuming it will qualify for refinancing.

Examples are hypothetical educational estimates, not market data, loan approvals or individualized investment, tax or legal advice. Verify property facts and financing terms with appropriate professionals.
