BRRRR Calculator: Analyze Buy-Rehab-Rent-Refinance-Repeat Deals

A BRRRR calculator helps real estate investors analyze the full cycle of a Buy-Rehab-Rent-Refinance-Repeat deal before committing capital. The BRRRR strategy has become one of the most popular methods for building a rental property portfolio with limited money because it is designed to recycle your cash. You force equity through renovation, pull that equity back out via a cash-out refinance, and end up with a cash-flowing rental with little to no money left in the deal. Then you repeat the process on the next property.

Analyzing a BRRRR deal is more complex than a simple flip or rental cash flow calculation because you must evaluate both the renovation economics and the long-term rental performance, plus the refinance step that bridges the two. This BRRRR calculator guide walks through each stage with formulas and a detailed worked example so you can run the numbers on any property.

The Five Stages of BRRRR

Stage 1: Buy

The first stage is acquiring a property below market value. BRRRR only works if you purchase at a significant discount because you need the spread between your total investment (purchase plus rehab) and the after-repair value to be large enough to refinance most or all of your capital back out.

Most successful BRRRR investors buy from motivated sellers, at auction, or through wholesalers. The target purchase price should be 60 to 75 percent of the after-repair value minus your estimated renovation costs. This is similar to the 70% rule used by flippers, but BRRRR investors can sometimes pay slightly more because they are not paying selling costs (they are keeping the property).

Financing for the initial purchase is typically cash or hard money. Traditional mortgages are difficult to obtain on properties in poor condition, and the BRRRR timeline requires quick closing. Hard money loans (short-term, asset-based loans at higher interest rates) are the most common financing vehicle for the buy and rehab phases.

Stage 2: Rehab

The rehabilitation stage is where you force equity into the property. Unlike a flip, where the renovation focuses on maximizing sale price, a BRRRR rehab focuses on creating a durable, tenant-ready property that will also appraise well for the refinance.

Key renovation priorities for BRRRR are slightly different from a flip. Durability matters more than luxury finishes. Luxury vinyl plank flooring, solid-surface countertops, and commercial-grade paint hold up better to tenant wear than the flashier finishes you might use on a flip. Systems (HVAC, plumbing, electrical, roof) should be brought to good condition to avoid costly repairs during the rental period. The renovation should bring the property to the standard of the comps you used to estimate ARV, but there is no benefit to significantly over-improving beyond that standard.

Typical BRRRR renovation timelines are 4 to 12 weeks depending on scope. Every week of renovation is a week of hard money interest payments, so speed matters.

Stage 3: Rent

Once the renovation is complete, you place a tenant. Some investors place a tenant before refinancing (which strengthens the refinance application by showing actual income), while others refinance first and then rent. The timing depends on your lender's requirements and how quickly you can find a qualified tenant.

To analyze the rental stage, you need to estimate monthly rental income based on comparable rentals in the area, monthly operating expenses, and resulting cash flow.

Monthly operating expenses include:

• Property management (8 to 10 percent of monthly rent)
• Property taxes (annual amount divided by 12)
• Insurance (annual premium divided by 12)
• Maintenance reserve (5 to 10 percent of rent)
• Vacancy reserve (5 to 8 percent of rent)
• Capital expenditure reserve (5 to 10 percent of rent for major items like roof, HVAC, water heater)
• HOA fees (if applicable)
• Future mortgage payment (from refinance — calculated in Stage 4)

Stage 4: Refinance

The refinance is the critical step that distinguishes BRRRR from a regular buy-and-hold. After the property is renovated (and ideally tenanted), you apply for a conventional cash-out refinance loan based on the property's new appraised value.

Most lenders will lend 70 to 80 percent of the appraised value on a cash-out refinance for investment properties. If the property appraises at or above your ARV estimate, and your total investment (purchase + rehab + holding costs) is less than 70 to 80 percent of that value, you get most or all of your cash back.

Key refinance considerations:

• Seasoning period: Many lenders require a 6 to 12 month "seasoning period" between the purchase date and the refinance. During this time, you are paying hard money interest. Some portfolio lenders and DSCR (Debt Service Coverage Ratio) lenders have shorter or no seasoning requirements.
• Appraisal: The appraised value determines how much you can borrow. If the appraisal comes in below your ARV estimate, you will leave more cash in the deal than planned.
• Interest rate: Investment property refinance rates are typically 0.5 to 1.0 percent higher than primary residence rates. As of early 2026, expect 7 to 8.5 percent depending on credit score, LTV, and lender.
• DSCR loans: These qualify based on the property's income rather than your personal income, making them popular with BRRRR investors who have multiple properties. The property's rental income must cover the debt service at a ratio of 1.0 to 1.25x depending on the lender.

Stage 5: Repeat

With your capital recovered from the refinance, you use those funds to acquire and renovate the next property, repeating the cycle. The power of BRRRR is compounding: each property you add generates cash flow and builds equity, and the capital you recover funds the next acquisition.

Complete BRRRR Calculation Example

Let us walk through a detailed example with realistic numbers.

Property: 3-bedroom, 1.5-bathroom single-family home, 1,400 square feet, built in 1988. Purchased from a wholesaler. Needs full cosmetic renovation (kitchen, bath, flooring, paint, landscaping) plus an HVAC replacement.

Acquisition and Rehab Phase

• Purchase price: $135,000
• Buying costs (title, recording, inspection): $2,500
• Rehab costs: $38,000
• Hard money loan: $135,000 at 12% interest, 2 points origination
• Hard money origination: $2,700 (2% of $135,000)
• Holding costs during rehab (3 months): Hard money interest $1,350/mo ($4,050 total) + insurance $150/mo ($450 total) + utilities $200/mo ($600 total) + taxes $350/mo ($1,050 total) = $6,150
• Total cash invested: $2,500 (closing) + $38,000 (rehab) + $2,700 (points) + $6,150 (holding) = $49,350
• Note: The purchase price was covered by the hard money loan, so your out-of-pocket is the non-financed costs

ARV and Refinance Phase

• After-repair value (appraised): $215,000
• Cash-out refinance at 75% LTV: $215,000 x 0.75 = $161,250
• Pay off hard money loan: $135,000
• Refinance closing costs: $3,500
• Cash back from refinance: $161,250 - $135,000 - $3,500 = $22,750
• Cash left in deal: $49,350 - $22,750 = $26,600

In this example, you have $26,600 left in the deal after the refinance. That is not zero (the ideal BRRRR outcome), but it is significantly less than the $49,350 you initially invested. Some deals allow you to pull out 100 percent of your cash (or even more than you invested), but realistic market conditions mean leaving $10,000 to $30,000 in many BRRRR deals.

Rental Cash Flow Phase

• Monthly rent: $1,650
• New mortgage payment (P&I at 7.5%, 30-year, $161,250 loan): $1,128
• Property taxes: $350/mo
• Insurance: $150/mo
• Property management (10%): $165/mo
• Maintenance reserve (5%): $82/mo
• Vacancy reserve (5%): $82/mo
• CapEx reserve (5%): $82/mo
• Total monthly expenses: $2,039
• Monthly cash flow: $1,650 - $2,039 = -$389

This deal is cash-flow negative at current interest rates with 75% LTV. This is an important reality check: in many markets with today's interest rates, BRRRR deals that look good on the acquisition side produce thin or negative cash flow on the rental side. This does not mean BRRRR is broken, but it does mean you need to be selective about which deals you pursue and honest about the numbers.

When Does This Deal Make Sense?

Even though the monthly cash flow is negative, this deal might still be worthwhile if you account for principal paydown (your tenant is paying off your mortgage, building equity), appreciation (even modest 3% annual appreciation on a $215,000 property adds $6,450/year), tax benefits (depreciation, mortgage interest deduction, expense deductions), and the equity you have built ($53,750 in day-one equity based on a $215,000 value with a $161,250 loan).

However, negative cash flow means you are subsidizing the property out of pocket every month. If you plan to scale to multiple BRRRR properties, negative cash flow on each one accumulates and can create financial pressure. The best BRRRR deals produce at least break-even cash flow.

Key Metrics to Calculate

Cash left in deal: Total cash invested minus cash recovered from refinance. The goal is to minimize this number.

Cash-on-cash return: Annual cash flow divided by cash left in deal. If you have $26,600 left in the deal and the property produces $2,400/year in cash flow, your cash-on-cash return is 9 percent. If the property is cash-flow negative, this metric is negative.

Total return: Cash flow + principal paydown + appreciation + tax benefits, divided by cash left in deal. This gives a more complete picture than cash-on-cash alone.

DSCR (Debt Service Coverage Ratio): Net operating income (rent minus expenses, excluding the mortgage) divided by the annual mortgage payment. Lenders typically require 1.0 to 1.25x. In our example: ($1,650 - $350 - $150 - $165 - $82 - $82 - $82) x 12 / ($1,128 x 12) = $739 x 12 / $1,128 x 12 = 0.65. This would not qualify for a DSCR loan without a higher down payment or higher rent.

Making BRRRR Work in Today's Market

Higher interest rates have made BRRRR more challenging than in the low-rate era of 2020 to 2022. To make it work today, focus on buying at deeper discounts (target 65% of ARV minus rehab instead of 70%), keep rehab timelines short to minimize holding costs, target markets with higher rent-to-price ratios, consider value-add opportunities that increase rent (adding a bedroom, converting a garage, adding a washer/dryer), and be willing to leave some cash in the deal rather than forcing a 100% capital recovery that produces negative cash flow.

BRRRR Calculator vs Traditional Rental Analysis

A traditional rental cash flow calculator only evaluates income minus expenses on a property you plan to buy and hold. A BRRRR calculator adds three additional dimensions that a standard rental analysis ignores:

• Forced appreciation through rehab. You are not buying at market value. You are buying below market, renovating, and creating equity that did not exist before. The calculator must model the gap between your all-in cost and the post-rehab appraised value.
• Capital recovery via refinance. The refinance step determines how much cash you pull back out. Your after-repair value, the lender's LTV limit, and refinance closing costs determine whether you recycle 80 percent of your capital or 100 percent.
• Two financing phases. You model short-term hard money during rehab (high rate, interest-only) and then long-term conventional financing after the refinance (lower rate, fully amortizing). Both affect your holding costs and eventual cash flow differently.

If you only run a rental analysis without modeling the rehab and refinance, you will miss the most important metrics in a BRRRR deal: cash left in deal, capital velocity, and whether the refinance is even feasible at current rates.

Frequently Asked Questions

What is a good cash-on-cash return for a BRRRR deal?

Most investors target 8 to 15 percent cash-on-cash return on BRRRR deals. However, in higher interest rate environments like 2025-2026, achieving positive cash flow at all requires buying at deeper discounts or targeting markets with strong rent-to-price ratios. Some investors accept lower cash-on-cash returns because BRRRR also builds equity through principal paydown and appreciation.

How long is the seasoning period for a BRRRR refinance?

Most conventional lenders require 6 to 12 months between purchase and cash-out refinance. DSCR lenders and some portfolio lenders offer shorter or no seasoning periods. During the seasoning period, you are paying hard money interest, so shorter seasoning directly reduces your holding costs.

Can you do BRRRR with no money down?

Technically yes, but it requires creative financing. If a hard money lender covers 100 percent of the purchase and rehab (some lend up to 90 percent of ARV), and the post-rehab appraisal supports a refinance that covers your entire investment, you can recover all your capital. In practice, most investors leave some cash in each deal, especially at current interest rates.

What is the difference between a BRRRR calculator and a flip calculator?

A flip calculator estimates profit from buying, renovating, and selling a property. A BRRRR calculator estimates cash left in deal and ongoing cash flow from buying, renovating, renting, and refinancing. The acquisition and rehab analysis is similar, but the exit strategy is completely different: selling versus holding long-term.

How do I estimate ARV for the BRRRR calculator?

Use 3 to 5 comparable sales within the last 12 months, within a half-mile to one-mile radius, with similar square footage, bedrooms, bathrooms, and post-renovation condition. Calculate the median price per square foot and apply it to your subject property. For more detail, see our BRRRR analysis guide.
