Calculators

Built for real deal math

Most online calculators stop at rent minus mortgage. These include vacancy, reserves, holding costs, fees and financing, the items that decide whether a deal actually works. Each page explains exactly how the numbers are calculated, so you can check the math yourself.

Share any result: every calculator can copy a link that reopens with your exact numbers, which is handy for sending a deal to a partner or lender.
