What is a brrr calculator?
A brrr calculator is a specialized financial tool designed for real estate investors using the **BRRRR method**, which stands for **Buy, Rehab, Rent, Refinance, Repeat**. This strategy focuses on acquiring undervalued properties, forcing appreciation through renovations, and then refinancing to pull out the initial capital to reinvest in another property. A good brrr calculator helps you analyze the viability of a deal by projecting key financial metrics like cash flow, return on investment, and, most importantly, the amount of cash you’ll have left in the deal after the refinance.
Unlike a standard rental property calculator, the brrr calculator specifically models the multi-stage process of this strategy, from initial purchase and renovation costs to the critical cash-out refinance step. It allows investors to quickly determine if a property meets their criteria for a successful BRRRR project—ideally, one where they can pull out all of their initial investment (or even more) while still maintaining positive cash flow.
brrr calculator Formula and Explanation
The magic of the BRRRR method lies in a series of interconnected calculations. This brrr calculator breaks down the process to provide clarity on a deal’s potential profitability.
Key Formulas:
- Total Initial Investment = (Purchase Price) + (Rehab Costs) + (Purchase Closing Costs)
- New Loan Amount = (After Repair Value) x (Refinance LTV %)
- Cash Out from Refinance = (New Loan Amount) – (Refinance Closing Costs)
- Total Cash Left in Deal = (Total Initial Investment) – (Cash Out from Refinance)
- Net Operating Income (NOI) = (Gross Monthly Rent) – (Monthly Operating Expenses)
- Monthly Mortgage Payment (P&I) = P * [r(1+r)^n] / [(1+r)^n – 1]
Where P is the new loan amount, r is the monthly interest rate, and n is the number of months. - Monthly Cash Flow = (Net Operating Income) – (Monthly Mortgage Payment)
- Cash on Cash Return (CoC) = (Monthly Cash Flow * 12) / (Total Cash Left in Deal) * 100
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Purchase Price | Cost to buy the property. | Currency ($) | Varies by market |
| Rehab Costs | Total cost of renovations. | Currency ($) | 10-25% of ARV |
| After Repair Value (ARV) | Property’s value after rehab. | Currency ($) | ~125-140% of Purchase + Rehab |
| Refinance LTV | Loan-to-Value for the new loan. | Percentage (%) | 70-80% |
| Monthly Rent | Income from tenants. | Currency ($) | Varies by market |
| Operating Expenses | Costs to run the property (taxes, insurance, etc.). | Percentage (%) | 35-50% of rent |
Practical Examples
Example 1: The “Perfect” BRRRR
An investor finds a distressed property and wants to see if they can pull all their money out.
- Inputs:
- Purchase Price: $100,000
- Rehab Costs: $40,000
- After Repair Value (ARV): $200,000
- Monthly Rent: $1,800
- Refinance LTV: 75%
- Refinance Interest Rate: 6.5%
- Results:
- Total Initial Investment: ~$144,000
- New Loan Amount: $150,000 (75% of $200k)
- Total Cash Left in Deal: ~$1,500 (Effectively getting paid to buy a house)
- Monthly Cash Flow: ~$350
- Cash on Cash Return: Very high (approaching infinite as investment is near zero)
Example 2: Leaving Some Cash In
In this scenario, the investor can’t pull all their cash out but still gets a great deal.
- Inputs:
- Purchase Price: $220,000
- Rehab Costs: $50,000
- After Repair Value (ARV): $330,000
- Monthly Rent: $2,800
- Refinance LTV: 75%
- Refinance Interest Rate: 7%
- Results:
- Total Initial Investment: ~$276,600
- New Loan Amount: $247,500 (75% of $330k)
- Total Cash Left in Deal: ~$29,100
- Monthly Cash Flow: ~$435
- Cash on Cash Return: ~17.9%
Even though the investor leaves money in the deal, a nearly 18% cash on cash return is an excellent result that a real estate ROI calculator would confirm is a strong investment.
How to Use This brrr calculator
Using this brrr calculator is a straightforward process designed to give you a quick yet comprehensive analysis of your potential investment.
- Enter Purchase and Rehab Data: Start by inputting the `Purchase Price`, your estimated `Rehabilitation Costs`, and the `After Repair Value (ARV)`. The ARV is crucial and should be based on comparable sales of similar, renovated properties in the area.
- Input Rental Income and Expenses: Add the projected `Gross Monthly Rent` and your estimated `Monthly Operating Expenses` as a percentage of that rent. A conservative estimate for expenses is typically 40-50%.
- Define Refinance Terms: Enter the lender’s `Refinance LTV` (usually 70-75% of ARV), the expected `Refinance Interest Rate`, and the `Loan Term`.
- Analyze the Results: The calculator instantly updates. The most important metric is the `Total Cash Left in Deal`. A negative or zero balance is the ideal BRRRR outcome. Also, check the `Monthly Cash Flow` to ensure the property is profitable and the `Cash on Cash Return` to measure performance if you do leave money in the deal.
Key Factors That Affect a BRRRR Deal
A successful BRRRR project depends on more than just the numbers. Several key factors can significantly impact your outcome:
- Accurate ARV Estimation: Overestimating the After Repair Value is one of the biggest risks. If the property appraises for less than you projected, the entire strategy can fail. You must learn how to calculate ARV accurately.
- Controlling Rehab Costs: Staying on budget during the renovation is critical. Unexpected issues can quickly eat into your profits and increase the cash you must leave in the deal. Always include a contingency fund (10-20% of the rehab budget).
- Financing Terms: The interest rate and LTV offered on the cash-out refinance directly determine your monthly payment and how much cash you can pull out. Higher rates can crush your cash flow.
- Market Rents: Your rental income must be sufficient to cover the new, larger mortgage payment and all operating expenses. Misjudging the local rental market can turn a good deal into a bad one.
- Holding Costs: Remember to account for costs incurred during the rehab and rent-up phase, such as loan payments on the initial financing, utilities, and taxes. This brrr calculator includes these in the closing cost fields as a proxy.
- The “Repeat” Step: The ultimate goal is to repeat the process. The success of this depends on your ability to find the next undervalued property, making deal-finding a crucial skill. It’s often a debate between a fix and flip vs brrrr strategy.
Frequently Asked Questions
1. What is the 70% rule in BRRRR?
The 70% rule is a guideline suggesting you should pay no more than 70% of the After Repair Value (ARV) of a property, minus the cost of repairs. For example, if a home’s ARV is $200,000 and needs $30,000 in repairs, you should aim to buy it for no more than $110,000 ($200k * 0.70 – $30k). Following this helps ensure you can refinance successfully.
2. Can you do the BRRRR method with no money down?
While difficult, it’s possible by using hard money loans or private financing for the purchase and rehab. The goal is then to have the cash-out refinance be large enough to pay back those initial lenders entirely, leaving you with zero of your own cash in the deal.
3. How long does the BRRRR process take?
Typically, the process takes 6-12 months. This includes finding the property, closing, completing the rehab (2-4 months), finding a tenant (1 month), and then going through the refinance process, which often requires a “seasoning period” of 6 months where the lender wants to see a history of ownership and rental payments.
4. What’s the difference between this and a flip?
The key difference is the exit strategy. A flip involves selling the property after rehab for a one-time profit. The BRRRR method involves keeping the property as a long-term rental asset, using the refinance to pull capital out for the next deal.
5. Is Cash on Cash Return infinite if I pull all my money out?
Mathematically, yes. If your “Cash Left in Deal” is zero or negative, you’re generating a return on no investment, so the percentage is infinite. Our brrr calculator will display “Infinite” or a very high number in this scenario to reflect this excellent outcome.
6. What happens if the property doesn’t appraise for the expected ARV?
This is a major risk. If the appraisal comes in low, your new loan amount will be smaller. This means you will not be able to pull out as much cash as planned and will likely have to leave a significant amount of your own capital in the deal, reducing your ROI.
7. Does the brrr calculator account for taxes?
This calculator does not model income tax or depreciation benefits. It focuses on the cash flow and capital recycling aspects of the deal. Property taxes should be included in your ‘Operating Expenses’ percentage.
8. Can I use a conventional loan for a BRRRR deal?
It can be difficult to use conventional loans for the initial purchase of a distressed property, as they often won’t pass appraisal standards. They are, however, the most common loan type for the final cash-out refinance step once the property is stabilized and rented.
