BRRRR Calculator

What is the BRRRR Strategy?

The BRRRR method stands for Buy, Rehab, Rent, Refinance, Repeat. This real estate investment strategy allows investors to build a rental property portfolio while recycling their initial capital. Instead of leaving all your money tied up in one property, you refinance after adding value through renovations, pull most of your cash back out, and use it to fund your next deal.

This calculator helps you model each phase of a BRRRR deal before you commit capital. By entering your purchase price, rehab budget, expected rent, and after-repair value (ARV), you can see exactly how much cash you'll have left in the deal after refinancing, what your monthly cash flow will look like, and whether the numbers justify the effort.

How to Use This BRRRR Calculator

Start by entering your purchase price and estimated rehab costs in phases one and two. These represent your total cash investment before refinancing. Next, input your expected monthly rent and any operating expenses like property management, insurance, or maintenance reserves. The calculator uses these to project your monthly cash flow after the refinance.

In phase four, enter your after-repair value—the appraised value you expect after renovations are complete. Most lenders will refinance at 75% loan-to-value on this new appraisal, which determines how much cash you can pull back out. Adjust the refinance LTV and interest rate to match your lender's terms, then hit calculate to see your full BRRRR projection.

Key Metrics Explained

Cash Left in Deal: This is the amount of your original investment that remains tied up in the property after refinancing. The goal of BRRRR is to minimize this number—ideally getting all your cash back or even pulling out more than you put in. If this number is negative, you've successfully recycled 100% of your capital.

Equity Captured: This represents the forced appreciation you created through renovations. It's the difference between your all-in cost (purchase plus rehab) and the new appraised value. This equity is what makes the refinance possible and protects you if the market softens.

Cash-on-Cash ROI: This metric divides your annual cash flow by the cash you have left in the deal. If you successfully pull all your money out, this number becomes infinite—you're earning cash flow with zero capital at risk. Even if you leave some cash in, a strong BRRRR deal should produce 15%+ cash-on-cash returns.

Why BRRRR Works for Portfolio Growth

Traditional rental investing requires you to save up a new down payment for each property, which can take years between acquisitions. The BRRRR strategy accelerates this timeline by letting you reuse the same capital multiple times. If you start with $50,000 and successfully execute a BRRRR deal, you can pull that $50,000 back out and immediately deploy it into your next property—all while keeping the first rental in your portfolio producing cash flow.

This capital recycling creates a compounding effect. Instead of buying one property every two years, experienced BRRRR investors can acquire multiple properties per year using the same initial capital. The key is finding properties below market value, accurately estimating rehab costs, and ensuring the after-repair value supports a refinance that returns most of your investment.

Common BRRRR Mistakes to Avoid

The biggest mistake is overestimating the after-repair value. If your property appraises lower than expected, you won't be able to refinance enough to pull your cash back out, leaving you stuck with more capital in the deal than planned. Always use conservative ARV estimates based on recent comparable sales, and consider getting a pre-renovation appraisal opinion from a local appraiser.

Another common error is underestimating rehab costs or timelines. Budget overruns eat directly into your equity and can turn a profitable BRRRR into a marginal deal. Build a 10-15% contingency into your rehab budget and get multiple contractor bids before you buy. Also factor in holding costs—mortgage payments, utilities, and insurance during the renovation period add up quickly and reduce your final returns.
