Frequently asked questions

Buy below value, Rehab to raise the value, Rent the property out, Refinance at the new value to recover your cash, then Repeat. This calculator models the refinance and recycle step where the strategy succeeds or fails.

Total cash you put in (purchase, rehab, holding and closing) minus what the refinance loan returns to you. Leaving $7,000 in a deal that cash-flows is usually considered a strong BRRRR outcome; leaving nothing means your capital is fully recycled.

The new loan is sized off the appraised after-repair value, not your costs: at 75% LTV on a $320,000 ARV the loan is $240,000. If the appraisal comes in low, the loan shrinks and more cash stays trapped in the deal.

Yes. The larger refinance loan carries a larger payment, so rent minus expenses minus the new payment can go negative even when the pre-refinance numbers looked fine. The monthly cash-flow output is the check.

A low refinance appraisal, lender seasoning rules that delay the refinance, rehab overruns, and rates rising between purchase and refinance. Any of them leaves more cash in the deal and cuts the return on the cash that stays.
