Best rental property calculator for BRRRR investors (2026)

Honest 2026 ranking of the best calculators for BRRRR — TrueCap, DealCheck, BiggerPockets, and what makes a BRRRR-specific calculator different from a standard rental analyzer.

Published 2026-06-07

Quick answer

For BRRRR investors specifically, TrueCap currently supplies separate rehab, ARV, DSCR, and stabilized-rental tools—not an integrated lifecycle model. Evaluate DealCheck or another released product if you need a joined acquisition-to-refinance ledger, and use a spreadsheet for financing structures that require custom cash-flow timing.

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 does it matter?
A capital-recovery ratio compares refinance distributions with every contribution made through that date, including acquisition, renovation, carrying, and financing costs. A distribution equal to contributions does not make the investment's return infinite: later contributions, operating cash flows, remaining equity, and time still matter.
What ARV (After Repair Value) should I use in a BRRRR analysis?
Build a range from relevant comparable sales and obtain qualified local valuation support. Stress-test the range, but do not treat a worksheet value as the future appraisal a lender will accept.
What refi LTV should I model for a BRRRR?
Use the eligible value, leverage limit, seasoning rule, debt-coverage requirement, fees, and cash-out limit from an actual lender quote. There is no single LTV that applies to every property, loan, or borrower.
Can I underwrite BRRRR deals in TrueCap today?
In pieces, yes. The released standalone tools cover rehab cost, ARV, and the 70% rule price screen, and the main analyzer returns DSCR, cap rate, and cash flow for the stabilized rental once you enter the post-refinance rent and loan terms. There is no separate DSCR calculator page — for the coverage test a lender will run, the how-to-calculate-DSCR walkthrough shows the arithmetic. The integrated BRRRR lifecycle model is not currently released, so use a complete project ledger or another released product for the joined cash-flow analysis.
