BRRRR basics: how the refinance returns your cash

Updated 2026-07-02

BRRRR. Buy, Rehab, Rent, Refinance, Repeat, is a way to recycle the same pool of cash across many deals. The magic is in the fourth step: a cash-out refinance that hands your money back so you can do it again.

1 · Buy
Below value
2 · Rehab
Force ARV
3 · Rent
Stabilize
4 · Refinance
Cash out

Why the refinance is the whole game

You buy and rehab with short-term money (cash, a HELOC, or hard money), which gets you into the deal below the after-repair value (ARV). Once it's rented and stabilized, a lender refinances based on that higher ARV, typically up to 70 to 75% of it, and the new loan pays off your short-term money and returns much of your original cash.

Cash left in deal = Total cash in − Cash returned at refinance
If the refinance returns everything you put in, your cash left is ~$0, and your cash-on-cash return effectively goes to infinity.

Where deals go wrong

  • ARV was optimistic. If the appraisal comes in low, the refinance returns less and you leave more cash stuck in the deal.
  • Rehab ran over. Every dollar over budget is a dollar you may not get back at refinance.
  • Rates moved. A higher refinance rate raises debt service and squeezes DSCR, which can cap how much the lender will give you.

BuyBox models the refinance as a first-class step, so you can see exactly how much cash comes back and what's left in the deal before you commit. A Deep Dive is where you tune it.
