The direct answer
The BRRRR sequence connects acquisition and rehab cash, an after-repair value assumption, refinance proceeds and ongoing rental cash flow. The central question is how much contributed cash remains after net refinance proceeds, not whether the acronym itself creates a return.
Build the project cash requirement
Sum purchase, acquisition, rehab and holding amounts in the scenario. Confirm whether the amounts represent cash contributions or financed spending. The simplified calculator treats the project total as contributed cash and does not separately track a bridge-loan payoff. If another loan must be repaid at refinance, reconcile that obligation before using proceeds as recovered investment capital.
To apply the approach to an editable scenario, use the BRRRR Calculator. For the neighboring question, explore ARV Calculator.
Treat refinance capacity as an assumption
Gross proceeds equal ARV times the entered refinance LTV, with separate refinance closing costs deducted. This does not indicate a lender commitment or an appraisal outcome. Test a lower ARV or lower LTV because either can leave more cash in the deal. A higher modeled valuation does not by itself mean that the project can obtain or support the proposed loan.
Evaluate the remaining rental separately
Annual rent less the entered operating costs and debt service gives the post-refinance cash flow. Dividing by positive remaining cash gives a cash-on-cash relationship. When net refinance cash equals or exceeds project cash, the remaining contribution is shown as zero and the ratio becomes unavailable. The rental can still require reserves and future capital, so an unavailable ratio is not a statement of zero risk.
Worked example
Project cash is $265,000. An ARV of $350,000 at 75% LTV yields $262,500 gross refinance proceeds; $5,000 fees leave $257,500 net. Remaining modeled cash is $7,500. At $6,000 annual rental cash flow, the simplified post-refinance cash-on-cash result is 80%.
Common mistakes and limitations
Ignoring an existing acquisition-loan payoff can materially overstate cash recovered. The simplified model needs assumptions consistent with how the project is actually funded.
Refinance eligibility, appraised value, seasoning rules, rates and loan costs are lender-specific and are not predicted by this calculator.
Frequently asked questions
Does the tool approve a refinance?
No. ARV and LTV are user assumptions, and the calculation does not evaluate lending eligibility.
Why is the return unavailable after all cash is recovered?
The annual cash-on-cash denominator is zero. Showing an infinite percentage would misrepresent the measure.
