How it works
The BRRRR refinance is the step that turns one renovation into a repeatable system: an appraiser confirms the after-repair value, a lender offers a fraction of it — classically 75% — and the new loan retires the old one, with any surplus wired back to you as cash-out. Whether that surplus actually recycles your capital decides everything. The math stacks four numbers: maximum new loan equals ARV times LTV; gross cash-out equals that loan minus the balance being paid off; closing costs, charged on the entire new loan, shave the wire down to net cash-out; and net cash-out minus everything you have deployed leaves the cash still trapped in the deal. A true BRRRR lands at zero or below — the property carries itself and your money moves on. Watch the second-order effect this calculator makes visible: borrowing the full 75% raises the payment, and a property whose rent cannot clear the new debt service forces you to feed it monthly from the very capital you just pulled out. Appraisal day is where paper ARVs meet evidence, so underwrite from closed comparables rather than hope.Formula
Max loan = ARV × LTV | Net cash out = max loan − payoff − closing% × max loan | Cash left = deployed − net cash out
Tips
- Order the appraisal only once closed comps support your ARV — surprises strand capital.
- Above 80% LTV expect mortgage insurance or pricing hits that erode the pull-out.
- Refi closing costs ride on the entire new loan; a 2-point cost is real money at scale.
- Stress-test the new payment against 90% of rent before committing to maximum LTV.
- Seasoning rules vary by lender — ask how long between purchase and refinance they require.
