Sound familiar?
A big closing check. What did the flip really make?
By the time you see the settlement statement, the overruns and the extra months are already paid for.
Hard money interest, points, insurance and utilities add up quietly while the project runs long.
Two flips, two lenders, one bank account. It’s hard to say how much you could put into the next deal.
A full sample year
See a finished year before you start yours.
The kit comes with a complete sample year for Ridgeline Renovations: three flips, two hard money loans and one cash purchase. One flip went to plan. One went 41% over its rehab budget. One is still in progress at year end.
Click around, see what every tab does, then open the blank tracker and do the same with your own projects.
Ridgeline Renovations is fictional. The numbers are a worked example, not a promise of results.

Deal Analyzer
Know your max offer before you buy.
Type in the after-repair value, the asking price, your rehab estimate and your loan terms. The Deal Analyzer works out the 70% rule, every cost from closing to commission, your projected profit, the cash you need to bring and the most you can offer for the profit you want.
Then it stress-tests the deal: a lower sale price, a rehab that runs over, or both.
A screening tool, not an appraisal. Your lender, agent and contractor still have the final word.
