FAQ

What makes a BRRRR calculator different from a standard rental calculator?
A BRRRR calculator models the cash-out refinance step — when you refinance after the rehab, what's your new mortgage balance (typically 75% of ARV), how much capital comes back to you, and what's the cash flow on the refinanced loan. Standard rental calculators stop at the initial purchase + financing; BRRRR calculators continue through the refi event.
What's 'capital recovered' and why is it the BRRRR metric that matters?
Capital recovered = (cash-out refi proceeds) ÷ (total capital invested including down payment + rehab + holding). If it's 100%+, you've pulled all your money back out and the deal is 'infinite return' (true return is undefined because your invested capital is zero). TrueCap surfaces this as a headline metric; DealCheck and BiggerPockets require you to read it from the cash-on-cash math.
What ARV (After Repair Value) should I use in a BRRRR analysis?
Pull a CMA from your agent or have an appraiser do a pre-rehab estimate. Use that as the central case. Then stress-test ±10% in TrueCap's sensitivity grid — if the deal still works at ARV minus 10%, you have margin. If it doesn't, you're betting the CMA was conservative.
What refi LTV should I model for a BRRRR?
75% is the standard cap from BRRRR-friendly DSCR + portfolio lenders as of 2026. Some lenders go to 80% on seasoned properties (6+ months of rental history). Default to 75% in your underwriting and adjust if you have a specific lender quote.
Can I underwrite BRRRR deals on a free tier?
Sort of. TrueCap's free tier handles standard cap rate / CoC / DSCR / cash flow on the property — enough to decide if it cash-flows post-refi assuming you know the math. The dedicated BRRRR analyzer (auto-calculated cash-out refi proceeds + capital recovered + infinite-return flag) is Pro ($19/mo). DealCheck and BiggerPockets gate BRRRR mode to paid tiers too.
