By purchasing undervalued properties, renovating them to increase their value, renting them out, and then refinancing, investors can pull their initial capital back out to repeat the process. Here is how the stages break down mathematically: 1. **Buy**: Purchase a distressed property below market value. Total initial cost equals purchase price plus sourcing and closing costs. 2. **Rehab**: Renovate the property. This increases the asset's After Repair Value (ARV) and makes it attractive to high-quality tenants. 3. **Rent**: Secure tenants to cover operating expenses and future mortgage costs. 4. **Refinance**: Replace the temporary acquisition/rehab capital with a long-term, low-rate conforming mortgage. Lenders typically cash out up to 70% to 80% of the new ARV. 5. **Repeat**: Use the refunded cash to buy the next property. ## The Math of a Perfect BRRRR Deal The primary goal of a BRRRR transaction is to minimize the **cash left in the deal**. A "perfect BRRRR" occurs when the refinance loan amount completely covers the purchase price, purchase closing costs, and rehab budget, resulting in a zero (or negative) net cash investment. Let's define the key equations: $$\text{Total Capital Invested} = \text{Purchase Price} + \text{Acquisition Costs} + \text{Rehab Budget}$$ $$\text{Refinance Loan Amount} = \text{ARV} \times \text{Refinance LTV \%}$$ $$\text{Net Cash Left in Deal} = \text{Total Capital Invested} - \text{Refinance Loan Amount}$$ $$\text{Equity Created} = \text{ARV} - \text{Total Capital Invested}$$ If the refinance loan amount is greater than the total capital invested, you achieve a **cash-out surplus**, meaning you got paid to acquire a cash-flowing asset. In this scenario, your Cash-on-Cash Return is infinite because you have no personal cash remaining in the property. ## Refinance Debt Service and Cash Flow Constraints While pulling 100% of your cash out sounds ideal, it increases the refinance loan balance, which raises your monthly mortgage payment (debt service). If the mortgage payment is too high, the property will have negative cash flow. Underwriting must balance cash extraction with debt service coverage to ensure the property remains self-sustaining. ## How to Use This Calculator Enter your purchase price, upfront acquisition costs (closing costs, inspection, sourcing fees), and rehab budget for the buy-and-rehab phase. Then enter the After Repair Value (ARV) you expect once renovations are complete, along with your refinance loan-to-value (LTV), interest rate, and term. For the rental side, enter expected monthly gross rent, an operating expense ratio, and any other fixed monthly costs not captured by that ratio. The operating expense ratio applies against gross rent to approximate taxes, insurance, maintenance, and vacancy combined — many investors start with the classic "50% Rule" and adjust it based on the property's actual expense history. The calculator returns how much cash is left in the deal after the refinance, the equity created, and the resulting pro forma monthly cash flow. ## Worked Example: A $150,000 Purchase with a $30,000 Rehab Budget Take a distressed single-family home purchased for $150,000, with $5,000 in acquisition costs and a $30,000 rehab budget — a total buy cost of $185,000. After renovation, the property appraises for a $240,000 After Repair Value (ARV). At a 75% refinance LTV, the new mortgage is $180,000 (240,000 × 0.75), leaving only $5,000 of cash left in the deal ($185,000 − $180,000) and creating $55,000 of forced equity ($240,000 − $185,000) — close to a "perfect BRRRR." But cash left in the deal is only half the underwriting picture. On a 30-year refinance at 6.5%, that $180,000 loan carries a monthly principal-and-interest payment of about $1,138. If the unit rents for $1,800/month gross and a 50% operating expense ratio is applied against that rent, plus another $400/month in other fixed costs, the pro forma monthly cash flow comes out to roughly **-$638** — a deal that looks close to perfect on paper but loses money every month once it is rented. This is exactly why BRRRR investors need to check pro forma cash flow, not just cash left in the deal, before committing to the refinance. Raising the rent, trimming the rehab budget, or shopping for a lower refinance rate are the levers to fix a deal like this. ## Related Calculators Compare this deal against a straight buy-and-hold using the [Rental Property ROI Calculator](/calculators/rental-property-roi-calculator) or the [Cap Rate Calculator](/calculators/cap-rate-market-calculator).

BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. It is a real estate investment strategy focused on forcing appreciation through renovation, renting to cover costs, and refinancing to pull out capital. ### What is a perfect BRRRR deal? A perfect BRRRR is a deal where the refinance loan amount (typically 75% of the After Repair Value) covers 100% of the purchase price, closing costs, and rehab expenses. This leaves $0 of personal capital in the deal. ### How is ARV calculated in a BRRRR deal? After Repair Value (ARV) is the estimated market value of the property after all renovations are completed. It is determined by analyzing recently sold comparable properties (comps) in the neighborhood that are in premium renovated condition. ### What does "cash left in the deal" mean? This is the net cash remaining in the property after the refinance. It is calculated as: (Purchase Price + Buying Costs + Rehab Cost) - Refinance Loan Amount. If positive, this is your long-term equity investment. ### How long do I have to wait to refinance? Most conventional lenders require a "seasoning period" of 6 to 12 months before they will refinance a loan based on the new appraised ARV. If you refinance sooner, they may limit the loan amount to a percentage of the original purchase price plus documented rehab costs. ### What is the seasoning period? The seasoning period is the minimum amount of time a property must be owned before a lender will allow a cash-out refinance based on its new appraised value (ARV) rather than the original purchase price. ### Can I get an infinite return on a BRRRR property? Yes. If you pull out 100% of your initial capital (or more) during the refinance phase, your cash left in the deal is $0 or negative. Since Cash-on-Cash Return is annual cash flow divided by cash left in the deal, the resulting return is mathematically infinite. ### What LTV is typical for a BRRRR refinance? Lenders typically allow a Loan-to-Value (LTV) ratio of 70% to 80% for cash-out refinances on investment properties, with 75% being the most common standard. ### How does the rehab budget affect BRRRR success? Every dollar spent on rehab must increase the ARV by more than one dollar (ideally a 1-to-1.5 or 1-to-2 ratio). If you overspend on renovations without increasing market value, you will leave a substantial amount of cash trapped in the deal. ### What are the risks of the BRRRR strategy? The primary risks are: (1) Appraising lower than expected (low ARV), leaving cash trapped; (2) Rehab cost overruns; (3) Rental income coming in lower than expected; and (4) Interest rates rising during the rehab phase, making the refinance mortgage too expensive. ## Related concepts - **After Repair Value (ARV)** — The estimated market value of a property after all planned renovations and repairs have been completed. - **Hard Money Loan** — A short-term, high-interest loan used by real estate investors to purchase and rehab properties quickly. - **Cash-Out Refinance** — A mortgage refinancing option where the new loan is larger than the existing loan, and the difference is paid in cash. ## Related guides - [House Flipping Guide: How to Calculate ARV, 70% Rule, and Profit Margin](https://dothecalculation.com/blog/property/house-flipping-guide) — Underwrite house flips with professional precision.
