How the BRRRR math works

A BRRRR runs on two loans. This calculator models both, using our BRRRR financing programs:

  1. The acquisition loan is a fix and flip loan: the lower of 90% of purchase plus rehab, or 75% of the after-repair value. Interest is estimated as interest-only on the full loan for the months until you refinance.
  2. The refinance is a DSCR rental loan sized at the loan-to-value you enter — cash-out goes up to 75% — on a 30-year schedule. It pays off the acquisition loan, and anything left over comes back to you.

Cash left in the deal = your cash in − cash back at the refinance. The closer to zero, the more of your money is free for the next one. A negative number means the refinance returned more than you put in.

The refinance also has to pass the rent test: rent ÷ the new monthly payment must clear the 1.05x DSCR minimum. If it doesn't, the refi has to be smaller — and more of your cash stays in.

Rates default to our "rates from" figures, which are the lowest offered, not a quote. Payments here include taxes and insurance but not HOA dues; add those to your expectations if the property has them.

Where the plan usually breaks

The appraisal comes in under your ARV, the rehab runs long, or the rent is lower than you hoped. Try the calculator with a 10% lower ARV and a few more months — if the deal still works, it's probably a good one. The full playbook is in our guide to BRRRR financing.
