Analyze your Buy, Rehab, Rent, Refinance, Repeat deal from start to finish
The BRRRR method — Buy, Rehab, Rent, Refinance, Repeat — is one of the most powerful strategies in real estate investing. Unlike a simple buy-and-hold, BRRRR allows investors to recycle their capital: you purchase a distressed property at a discount, renovate it to force appreciation, place a tenant to generate rental income, refinance based on the new After Repair Value (ARV), pull out most or all of your original cash, and then repeat the process with a new deal. When executed correctly, a single pool of capital can fund many properties over time, dramatically accelerating your portfolio growth. The math behind a BRRRR deal is more complex than a standard rental analysis. You must account for the purchase price, closing costs, renovation costs, holding costs during rehab, and the financing structure both before and after the refinance. Many investors underestimate their true all-in cost by forgetting holding costs — things like interest on a hard money loan, property taxes, and insurance during the renovation period. Our BRRRR calculator walks you through every phase and makes sure nothing is overlooked. Refinancing is the heart of the BRRRR strategy. Lenders typically offer cash-out refinances at 70–80% of the ARV. The goal is to have your total investment (purchase + rehab + holding costs) come in below this refinance amount so that you can pull all — or more than all — of your cash back out. When cash recouped reaches 100% or more, investors call this an 'infinite return' because future cash flow is generated without any remaining capital at risk in the property. Cash-on-Cash (COC) return is the primary return metric for BRRRR deals with remaining capital in the deal. It measures annual cash flow as a percentage of the cash you have left invested after refinancing. A COC of 12–20% is considered solid; above 20% is excellent. Cap rate (NOI divided by ARV) provides a property-level metric independent of financing — useful for comparing properties across different loan structures. Our calculator goes beyond the basics. The ARV sensitivity table shows how your returns change if the property appraises higher or lower than expected — a critical risk analysis tool. The 5-year cash flow projection factors in rent growth and expense inflation so you can see the long-term trajectory of the deal. Whether you are evaluating your first BRRRR or your fiftieth, this tool gives you the complete picture.
Understanding the BRRRR Method
What Is the BRRRR Method?
BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. It is a real estate investment strategy where an investor purchases a distressed or undervalued property at a discount, renovates it to increase its value (forcing equity), rents it to a tenant to generate monthly income, then does a cash-out refinance based on the improved After Repair Value. The refinance proceeds are used to repay the original purchase capital, which is then recycled into the next deal. The power of BRRRR lies in capital efficiency — unlike a traditional rental purchase where your down payment is permanently tied up, BRRRR can return 80–100%+ of your invested capital so you can repeat the cycle and compound your portfolio without needing a new infusion of savings for every property.
How Are BRRRR Returns Calculated?
The BRRRR analysis flows through four sequential phases. In the Buy phase, you calculate your total acquisition cost (purchase price plus buying closing costs) and cash needed at closing (reduced by any hard money or purchase loan). In the Rehab phase, you add renovation costs and holding costs (monthly costs like loan interest, taxes, and utilities multiplied by the rehab duration) to get your total all-in investment. In the Rent phase, you calculate monthly NOI (gross rent minus all operating expenses: taxes, insurance, management, maintenance, vacancy, CapEx, and other). In the Refinance phase, the lender appraises the improved property at ARV and lends you LTV% of that value. Subtracting refinance closing costs and any initial loan payoff gives you net proceeds. Cash left in deal equals total investment minus net proceeds. Cash-on-Cash Return equals annual cash flow divided by cash left in deal.
Why Does the BRRRR Method Matter?
BRRRR matters because it solves the biggest constraint in real estate investing: capital. Traditional buy-and-hold requires a 20–25% down payment on every property, which means your capital base limits how many properties you can own. BRRRR breaks this constraint by recycling capital. An investor with $100,000 could potentially buy one traditional rental — or use that same $100,000 to acquire multiple BRRRR properties if each deal returns 80–100%+ of capital through refinancing. This multiplication effect is why BRRRR investors can build large portfolios much faster than traditional landlords. Additionally, BRRRR properties are purchased below market value, providing built-in equity from day one, a buffer against market downturns, and better refinance outcomes.
Limitations and Risks of BRRRR
BRRRR carries significant risks that a calculator cannot fully capture. Renovation cost overruns are extremely common — even experienced investors routinely face surprises behind walls. ARV is an estimate, not a guarantee; if the property appraises lower than expected, you may leave much more cash in the deal than planned. Interest rates change, and the refinance rate you use today may not be available when your project completes. Lenders impose seasoning requirements (typically 6–12 months of ownership before a cash-out refinance is allowed), which affects your timeline assumptions. Property management quality dramatically affects actual vacancy and maintenance costs. And holding costs compound quickly — every extra month of rehab reduces your returns substantially. Always build in conservative buffers on renovation costs and ARV, and have contingency cash available.
Formulas
Total All-In Investment
Total Investment = Cash at Purchase + Renovation Cost + (Monthly Holding Cost × Rehab Months)
Your true cost basis, including all cash spent before the refinance.
Refinance Loan Amount
Refi Loan = ARV × Refinance LTV%
The gross amount the lender provides based on the appraised After Repair Value.
Cash Left in Deal
Cash Left = Total Investment − Net Refinance Proceeds
If zero or negative, you have achieved an infinite return — all capital has been recycled.
Cash-on-Cash Return
COC = (Annual Cash Flow ÷ Cash Left in Deal) × 100
Annualized return on the equity you have remaining in the property after refinancing.
Cap Rate
Cap Rate = (Annual NOI ÷ ARV) × 100
Property-level return metric independent of financing structure.
Monthly Mortgage (P&I)
M = P × [r(1+r)^n] / [(1+r)^n − 1]
Standard amortization formula where P = loan amount, r = monthly rate, n = total payments.

Worked Examples
Classic BRRRR Deal — Infinite Return
A $150,000 distressed property in a mid-size city. Needs $30,000 in renovations. ARV estimated at $220,000. Hard money loan at 70% LTV. 3-month rehab at $500/month holding costs. Refinance at 75% LTV.
Total Acquisition: $150,000 + 3% closing costs ($4,500) = $154,500
Cash at Purchase (with 70% hard money loan): $154,500 − $105,000 = $49,500
Total Rehab + Holding: $30,000 + ($500 × 3) = $31,500
Total Investment: $49,500 + $31,500 = $81,000
Refinance Loan: $220,000 × 75% = $165,000
Net Proceeds (after 2% refi closing): $165,000 − $3,300 − $105,000 (payoff) = $56,700
Cash Left in Deal: $81,000 − $56,700 = $24,300
Monthly Mortgage (7%, 30yr): $991
Monthly Rent $1,800 − $900 OpEx − $991 Mortgage = −$91 cash flow
70% capital recovered. Slightly negative cash flow suggests negotiating a lower purchase price or increasing rent before committing. Illustrates the importance of buying at the right price.
How to Use the BRRRR Calculator
Enter Buy & Rehab Costs
Start with your purchase price and estimated closing costs. Add the renovation budget and the rehab duration in months. If you are using a hard money or bridge loan to fund the purchase, toggle on 'Finance the purchase' and enter the loan LTV, interest rate, and term. Monthly holding costs (loan interest, taxes, insurance during renovation) multiply by the rehab duration to give your true all-in cost.
Set Your ARV and Refinance Terms
Enter the After Repair Value — the estimated market value once renovations are complete. Use comparable sales (comps) from the past 3–6 months in the same neighborhood. Then set your refinance LTV (typically 70–80%), the expected interest rate, loan term (usually 30 years), and refinance closing costs. The calculator will show you the refinance loan amount and net proceeds.
Add Rental Income and Operating Expenses
Enter the expected monthly rent based on comparable rentals in the area. Then fill in your operating expenses: annual property taxes and insurance, property management percentage (8–10% is typical), maintenance and CapEx reserves (each 5–10% of rent is recommended), and vacancy rate (5–10% is standard for most markets). The calculator computes your monthly NOI and cash flow after the refinance mortgage payment.
Review the Deal Summary, Sensitivity, and Projections
The Deal Summary tab shows your complete BRRRR phase breakdown, cash recouped percentage, cash-on-cash return, and deal quality rating. Switch to ARV Sensitivity to see how returns shift if the property appraises within ±15% of your target. The 5-Year Projection tab shows cash flow and equity growth over time. Use Export CSV or Print to save the analysis for your records or to share with partners or lenders.
Frequently Asked Questions
What is a good cash-on-cash return for a BRRRR deal?
For BRRRR deals where capital remains in the property, a cash-on-cash return of 8–12% is considered average, 12–20% is good, and above 20% is excellent. However, the ultimate BRRRR goal is an 'infinite return' — when your net refinance proceeds equal or exceed your total investment, you have recovered 100% of your capital. At that point, all future cash flow is earned on zero remaining investment, making the theoretical return infinite. Most experienced BRRRR investors target at least 75% capital recovery and a COC of 12%+ on remaining cash.
What LTV can I expect on a BRRRR cash-out refinance?
Most conventional lenders offer 70–80% LTV on investment property cash-out refinances. Fannie Mae and Freddie Mac conforming loans typically allow up to 75% LTV for single-family investment properties. Some portfolio lenders and local banks may go to 80%. Hard money lenders sometimes offer higher LTVs but at significantly higher rates. Many lenders also require a 6–12 month seasoning period — meaning you must have owned the property for that long before they will use the ARV (rather than purchase price) as the basis for the refinance amount. Always confirm seasoning requirements before buying.
How do I estimate the After Repair Value (ARV) accurately?
ARV is estimated using comparable sales (comps) — recently sold properties (ideally within the past 3–6 months) that are similar in size, age, condition, and location to your renovated property. Pull comps from the MLS, Zillow, or Redfin and find 3–5 properties within 0.5–1 mile that sold in the renovated condition you are targeting. Average their price per square foot and apply it to your property. It is wise to be conservative: use the lower end of the comp range, not the highest. Having a licensed appraiser or experienced real estate agent review your ARV estimate before committing to a purchase is strongly recommended.
What are typical holding costs during the rehab phase?
Holding costs are often underestimated by new BRRRR investors. If you financed the purchase with a hard money loan (typical rates: 10–15% interest-only), the monthly interest alone on a $150,000 loan at 12% is $1,500 per month. Add property taxes (1–2% of purchase price annually, or $125–250/month on a $150,000 property), hazard insurance ($100–200/month), and utilities if you maintain them during renovation. A 3-month rehab with $1,800/month in holding costs adds $5,400 to your all-in cost — a number that can meaningfully impact your cash recouped percentage and deal quality.
What is the 50% rule and how does it apply to BRRRR?
The 50% rule is a quick screening heuristic that says operating expenses (excluding the mortgage) on a rental property will equal approximately 50% of gross rent. If a property rents for $1,800/month, operating expenses should be budgeted at roughly $900/month. This rule is useful for rapid deal screening — if rent minus 50% rule expenses minus your expected mortgage payment yields negative cash flow, the deal likely does not pencil. However, the 50% rule is a rough estimate; actual expenses vary significantly by market, property age, and local tax rates. Our calculator lets you input precise expense figures for a more accurate analysis.
Can BRRRR work in a high-priced market?
BRRRR is more challenging but not impossible in high-priced markets. The key constraints are: the spread between purchase price (distressed) and ARV must be large enough to cover rehab costs and still produce a favorable refinance, and rents must be high enough to generate positive cash flow after the refinance mortgage payment. In markets like coastal California, New York, or Seattle, cap rates are so compressed (often 3–5%) that cash flow after a conventional mortgage is rarely positive. Many BRRRR investors in expensive markets target secondary cities within those metros, or look to other states with stronger rent-to-price ratios. The ARV Sensitivity tab in this calculator shows how sensitive your specific deal is to property value assumptions.
