Why RealPropTools

Sized the way lenders size

Loans are tested on value, coverage and debt yield together, the smallest wins, and the page tells you which test set the number.

Matches your term sheet

30/360 and Actual/360 interest, stub interest at closing, interest-only periods and the balloon at maturity, calculated rather than approximated.

Private, free, no sign-up

Everything is calculated in your browser and nothing you type is sent anywhere. Share a scenario with a link when you want a second opinion.
