About half of this comes back at resale — the rest buys you the use and enjoyment in the meantime. A reasonable trade if you plan to stay a while.

“Net cost” = cost − resale value added: the part you don't recoup at sale, not a loss.

Estimates are for planning purposes only. Actual costs, resale value and ROI may vary by market, property condition, project scope, contractor pricing and timing. This is general information, not financial, investment, construction, legal or tax advice.

Two tools for a flip

Start free: use the ROI calculator to see which renovations recoup the most of their cost, so your rehab budget goes to upgrades that help resale and move the property faster.

Then underwrite the deal: the Renovation Deal Analyzer runs the full flip P&L, a 70%-rule max offer, rehab scope, a sensitivity grid and a plain-English verdict — plus a BRRRR tab for refinance-and-hold.

Underwrite before you bid

The margin on a flip is made on the buy. Model the numbers first — purchase, rehab, holding and selling costs against after-repair value — so you only bid on deals that actually pencil.

Who it's for

Fix-and-flip

Estimate rehab ROI and stress-test the deal before you make an offer.

BRRRR investors

Weigh refinance-and-hold against a straight flip, including cash flow.

First-time flippers

Learn which upgrades recoup the most and which quietly lose money.

Frequently asked questions

Is there a free house flip calculator?

Yes — the renovation ROI calculator on this page is free and shows cost, resale value added and ROI for 30+ projects. For full deal underwriting (profit, max offer, BRRRR), the Renovation Deal Analyzer is a paid spreadsheet.

What is the 70% rule?

A quick screen: many flippers aim to pay no more than 70% of a property’s after-repair value (ARV) minus rehab costs. The Deal Analyzer calculates a 70%-rule max offer for you.

Does it cover BRRRR deals?

Yes — the Deal Analyzer includes a BRRRR tab for buy-rehab-rent-refinance-repeat, with refinance loan, cash left in the deal, cash flow, cash-on-cash and cap rate.
