How to use it
Enter the purchase price
What you plan to pay. Buy closing costs for the state are added for you.
Enter the rehab
Your contractor's number or your own estimate. A 10% contingency is added on top, the way the app treats a typed bid.
Enter the ARV
What it sells for after the work. Not sure? Read how to calculate ARV.
Pick financing and months
Hard money uses 11%, 2 points, $1,500 in fees, 90% of the price and 100% of the rehab, with interest only on money drawn. These are planning defaults, not a quote.

Questions
Why is the profit lower than price minus ARV minus rehab?
Because a flip has more costs than that. Points are charged on the whole loan, interest runs every month, buy closing includes title and recording taxes, and selling costs include commission, concessions and transfer tax. The calculator lists each one.
How is the max offer figured?
It tries prices until it finds the highest one that still clears a $30,000 profit and a 12% margin on ARV, running the full math each time, then rounds down to the nearest $500. The 70% rule is shown next to it for comparison.
Are the loan terms real?
They are common hard money terms used as planning defaults. Every lender is different. In the app you set your own lender's terms once and they fill every deal.
