Fix & Flip Profit Visualizer

Know your profit before you swing a hammer.

I flip houses. I used to run these numbers in a spreadsheet on my laptop while standing in the driveway of the house I was looking at. Now it is this, on my phone, in about thirty seconds. Back to tools

Your flip

Pre-filled with a sample deal. Change anything.

Buy
= $4,950
= $0

Closing covers both sides when you pay the seller’s side too. Set the listing commission you’re covering on MLS deals, leave at 0 for off-market.

Fees you pay to acquire, a finder/acquisition fee and any wholesaler’s assignment fee. Both are costs on this deal; your gap lender can cover them too.

Rehab
Itemized rehab total$40,000
Rehab + buffer $44,000
Sell
Optional. Lock your before-flip estimate here, then update the deal to actuals when it closes, the Project Summary PDF shows projected vs. actual.
Comps for the lender PDF, optional

How are you funding it?

Toggle each lender on or off, run hard money only, private/gap only, both, or turn both off for an all-cash buy.

Hard money (1st lien)

= $2,665
= $0

Many hard-money lenders charge a fee each time you pull a rehab draw. Most rehabs run 3–6 draws.

Interest is figured on the full rehab from closing, the conservative case. In practice your lender holds the rehab back and you draw it in phases (or one draw at the end), so your real interest usually runs a bit less.

Private / gap money (2nd), no money down

Hard money funds most of purchase + rehab; your private/gap lender covers the rest, closing, fees, holding, interest, so none of your own cash goes in. Gap is interest-only.

Holding costs while you own it
Holding / month $787

Same flip, funded four ways

Cash buys the most profit; leverage buys the best return on your money. The no-money-down row is how most pros actually run it. Live on the deal above.

What if you’re wrong?

The honest test of a flip: does it still survive when the market cools or the rehab runs over? Profit at each outcome, on your current timeline.
