Frequently asked questions

Is the multifamily calculator free?

Yes. Your first analysis includes every Pro feature and you always see your full results. After that, a free tier stays free for basic analyses, and Pro is $29 per month for unlimited full underwriting.

What does the calculator compute?

Net operating income, cap rate, DSCR, cash-on-cash return, IRR, and long-term projections, with support for value-add scenarios and partnership waterfall structures.

Can I enter units individually?

Yes. The rent roll supports unit-by-unit entry with different rents per unit, or bulk entry when units are similar.

What size buildings does it handle?

It is built for apartment buildings and uses commercial underwriting conventions: NOI, cap rate, and DSCR. For 1-4 unit residential deals, the Single Family Rental Calculator is purpose-built with residential loan types.
