House Hack Calculator

See what living in your own small multifamily really costs. Enter the purchase, financing and rents for the units you won't occupy, and the calculator shows your effective housing cost after tenant rents offset the mortgage, so you can compare it to renting.

It also projects post-move-out cash flow once you rent your own unit too, runs an FHA 3-4 unit check (the self-sufficiency test for 3-4 unit FHA loans), and puts up to 3 properties side by side in a comparison so you can pick the best house hack.
