BRRRR Calculator
Use this focused BRRRR calculator. BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat.
It is an advanced real estate investment strategy designed to build a rental portfolio using velocity of capital. By purchasing undervalued properties, renovating them to increase value, renting to tenants, and doing a cash-out refinance based on the new After Repair Value (ARV), investors can pull out their initial capital to purchase their next property. This premium tool models cash requirements, refinance cash-out thresholds, trapped net capital, and post-refinance yield returns.

How to use this BRRRR calculator
Key inputs for BRRRR modeling
To analyze a BRRRR transaction, you need to collect several purchase, rehab, and financing inputs:
- Purchase Price: The acquisition purchase price of the distressed property.
- Rehab Cost: Total budget dedicated to renovation, permitting, and repairs.
- After Repair Value (ARV): The estimated market valuation of the property post-renovation.
- Refinance LTV (Loan-to-Value): The mortgage percentage limit offered by the refinance bank (typically 70% to 80%).
- Refinance Terms: Interest rate and amortization period (e.g. 30 years) for the new cash-out mortgage.
- Post-Refinance Rent & Opex: Estimated monthly rent and operational expenses to check post-refinance cash flow.
Reading the BRRRR outputs
The calculator details the capital recycling flow. First, it sums the Total Initial Cash Invested (Purchase + Rehab).
Next, it models the New Mortgage Amount derived from the ARV and LTV. Comparing this mortgage to the initial cash invested yields the Cash Out Recouped and the Net Trapped Capital (cash left in the deal). The model also calculates the property's post-refinance monthly cash flow and Cash-on-Cash (CoC) return.
BRRRR methodology and core formulas
BRRRR formulas
The velocity of capital in a BRRRR deal depends on the relationship between initial costs, ARV, and the refinance LTV:
The 'Perfect' BRRRR deal concept
In real estate, a "Perfect BRRRR" is a transaction where the refinance loan amount matches or exceeds the total initial cash invested. In this scenario, the investor pulls 100% of their cash back out of the deal while retaining ownership of the cash-flowing asset.
To achieve this, the purchase price plus rehab costs must not exceed 70% to 75% of the final ARV (complying with the bank's maximum refinance LTV). This demands buying properties at a significant discount and managing renovation expenses closely.
Step-by-step BRRRR deal analysis
Deal assumptions
Consider an investor purchasing a distressed single-family home using cash or a short-term hard money loan:
- Purchase Price: $100,000
- Rehab Cost: $40,000
- After Repair Value (ARV): $200,000 (based on local comparables)
- Refinance Bank LTV: 75% at 6.5% interest rate
- Projected Monthly Rent: $1,800
- Monthly Operating Expenses: $600
Underwriting and refinancing steps
- Calculate initial cash invested:
Total Invested = $100,000 + $40,000 = $140,000. - Determine Refinance Loan Amount:
New Loan = $200,000 ARV * 75% LTV = $150,000. - Analyze cash out and trapped capital:
Since the new loan ($150,000) exceeds the initial costs ($140,000), the investor pulls all initial cash out and receives $10,000 cash back at refinancing. Net trapped capital is $0 (infinite return). - Check monthly cash flows:
Monthly Mortgage (P&I) on $150k Loan = $948.
Monthly Net Cash Flow = Rent ($1,800) - Expenses ($600) - Mortgage ($948) = $252.
Strategic execution and common BRRRR mistakes
Overestimating the ARV
A major risk in BRRRR investing is assuming an optimistic ARV. If the final appraisal is lower than expected (e.g. $170,000 instead of $200,000), the bank will issue a smaller refinance loan. This leaves significant capital trapped in the deal, stalling the repeat phase.
Ignoring seasoning period rules
Lenders often enforce a "seasoning period" (typically 6 to 12 months) before they will refinance a property based on its new appraised value. During this time, investors must carry the higher interest rates of their initial acquisition or hard money loans, which reduces deal profitability.
Neglecting cash flow viability
While pulling 100% of cash out of a deal is ideal, the larger refinance mortgage increases monthly debt service payments. If rental rates are too low, the property can become cash flow negative post-refinancing, creating an unstable asset.
Frequently asked questions (FAQ)
How does hard money financing work in BRRRR?
Hard money loans are short-term, asset-based loans used to acquire and renovate distressed properties quickly. Because traditional banks rarely finance distressed properties, investors use hard money for the initial buy and rehab, then refinance into a traditional long-term mortgage once the property is renovated and rented.
What is the seasoning period in mortgage refinancing?
The seasoning period is the length of time an investor must own a property before a bank will refinance the mortgage based on its current appraised value, rather than the original purchase price. Seasoning requirements vary by lender but typically range from 6 to 12 months.
Can I use the BRRRR strategy for multifamily properties?
Yes. The BRRRR strategy is highly scalable and works well for multifamily properties. Commercial multifamily appraisals are based on Net Operating Income (NOI), giving investors more control over the final ARV through property improvements and rent optimization.
Real-world case study: U.S. Single-Family Rental Investment Benchmark (2024-2025 Benchmark)
U.S. Single-Family Rental Investment Benchmark metrics profile
This case study illustrates a common BRRRR (Buy, Rehab, Rent, Refinance, Repeat) strategy using realistic market benchmarks for single-family rental properties in the U.S. The scenario demonstrates how an investor can acquire a distressed property, add value through renovations, and then refinance to pull out their initial capital, setting the stage for future investments.
This benchmark case demonstrates a successful BRRRR strategy, where the investor is able to recoup their entire initial cash investment of $260,000 and pull an additional $2,500 out in cash during the refinance stage. The after-repair value (ARV) of $350,000, combined with a 75% LTV refinance, provides sufficient equity to achieve this outcome. The resulting monthly cash flow, after accounting for the new $1,748 mortgage payment (excluding taxes, insurance, and other operating expenses), would need to be further analyzed to determine the property's overall profitability and cash-on-cash return, making it attractive to investors seeking to recycle capital for further acquisitions.
