🚀 ROCKET

Capital recovered is 95% or more AND rehab cost is $50,000 or less. You pulled essentially all your cash out. Ready to repeat immediately.

⚡ STEADY

Capital recovered is 80% or more AND rehab cost is $75,000 or less. Solid deal. Minor capital remains tied up but the cycle is efficient.

🐢 SLOW

Recovery below 80% or rehab cost too high. Capital is tied up longer. May still be a good hold, but you will need fresh capital for the next deal.

How to use this calculator
1

Enter acquisition and rehab

Purchase price plus all-in rehab cost. Be conservative — scope creep is the #1 deal killer.

2

Set your ARV and refi terms

Use a conservative ARV from comparable sales, not the optimistic ceiling. Set LTV at what your lender will actually approve.

3

Enter rent and expenses

Monthly operating expenses should include taxes, insurance, PM fee, and maintenance reserve — everything except the mortgage.

4

Read the velocity score

ROCKET means you can do it again. SLOW means your next deal needs fresh capital. Know before you commit.

The formulas
Refi Loan = ARV × (LTV / 100)
Total Deployed = Purchase Price + Rehab Cost
Capital Recovery % = (Refi Loan / Total Deployed) × 100
Cash Left in Deal = Total Deployed - Refi Loan
Monthly Mortgage = standard amortization(Refi Loan, Rate, Term)
Monthly Cash Flow = Rent - Expenses - Monthly Mortgage
CoC Return = (Annual Cash Flow / Cash Left in Deal) × 100
Common BRRR mistakes

Using an optimistic ARV

Overstating ARV inflates your projected refi loan and makes recovery look better on paper. Use the median of 3+ closed comps within a half mile, same bed/bath count, sold within 6 months.

Underestimating rehab scope

Add 15-20% contingency to every rehab budget. Unexpected structural issues, permitting delays, and material cost increases happen on most projects. Budget for reality, not the estimate.

Ignoring the seasoning requirement

Many conventional lenders require 6-12 months of ownership before a cash-out refi. During that window your capital is tied up. Plan your timeline and cash reserves accordingly.

Chasing recovery rate at the expense of cash flow

Pulling every dollar out via a high-LTV refi leaves a large mortgage payment that can push cash flow negative. The goal is both — strong recovery AND positive monthly cash flow.

Frequently asked questions
What is the BRRR strategy in real estate?
BRRR stands for Buy, Rehab, Rent, Refinance, Repeat. Investors buy undervalued or distressed properties, renovate to force appreciation, rent to generate income and qualify for financing, then refinance to pull out equity and redeploy capital into the next deal.
How do you calculate BRRR returns?
The primary metric is capital recovery rate: Refi Loan divided by Total Cash Deployed (purchase + rehab) times 100. Secondary metrics are monthly cash flow and cash on cash return on remaining capital. A great BRRR recovers 90%+ of capital while maintaining positive cash flow.
What is capital recovery in a BRRR deal?
Capital recovery is the percentage of your total invested cash that comes back to you through the refinance loan. 100% recovery means the refi returned every dollar you put in. Above 100% means you pulled out more than you invested — your equity is now the lender's money.
What is the difference between BRRR and buy and hold?
Buy and hold ties your down payment in the deal indefinitely. BRRR recycles it. A BRRR investor with $150,000 can potentially control 5-6 properties over 3-4 years if each deal achieves 90%+ capital recovery. A buy-and-hold investor with the same capital might own 2-3 properties over the same period.
