BRRRR Analysis: How to Run the Numbers Before You Buy

This guide is part of our Deal Analysis Toolkit series.

BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. The strategy is straightforward in concept: buy a distressed property below market value, renovate it to rental-ready condition, place a tenant, refinance based on the new appraised value to pull your capital back out, and repeat the entire process with the same money. Executed well, BRRRR lets you build a rental portfolio with a finite amount of capital. Executed poorly, it traps your money in underperforming properties that you cannot refinance out of.

The difference between those two outcomes is the analysis you do before you buy. BRRRR analysis is more complex than a simple flip analysis or a simple rental analysis because you are running three analyses at once: a flip-style acquisition and rehab analysis, a rental cash flow analysis, and a refinance feasibility analysis. If any of the three fails, the strategy breaks.

Why BRRRR analysis is different

A flipper only cares about the spread between the all-in cost and the sale price. A buy-and-hold landlord only cares about cash flow and long-term appreciation. A BRRRR investor cares about both of those, plus a third number: how much capital gets trapped in the deal after refinancing.

This makes BRRRR the most analytically demanding strategy in residential real estate. You need accurate numbers in five areas, and weakness in any one of them can sink the deal.

The 5 numbers you need to know

1. All-in cost (purchase price + rehab cost + closing costs). This is the total capital deployed before any income or refinancing.
2. After Repair Value (ARV). What the property will appraise for after renovation. This determines your maximum refinance amount. Not what you think it is worth. Not what Zillow says. What an appraiser will put on paper. See our guide on how to calculate ARV for the methodology.
3. Monthly rent (ARR). What the property will rent for after renovation. This determines your cash flow after you take on the refinanced mortgage. Use after-repair rental comps, not as-is rental comps. See ARV vs ARR for guidance.
4. Refinance loan amount. Typically 75% of the appraised value (ARV). Some lenders go to 80%, some only 70%. The LTV ratio your lender offers is a hard constraint.
5. Capital remaining in the deal. All-in cost minus refinance proceeds. The goal is zero. If you pull all your capital out, your cash-on-cash return is theoretically infinite because you have no money in the deal. If capital remains trapped, you calculate your return on that remaining amount.

Step 1: Acquisition analysis

The acquisition analysis for a BRRRR is identical to a flip. You need a purchase price that leaves enough spread between your all-in cost and the ARV for the refinance to make sense.

Calculate your total acquisition cost:

• Purchase price: The contract price. For BRRRR to work, you typically need to buy at 65 to 75% of ARV minus rehab costs.
• Closing costs: 1 to 2% of purchase price (title, recording, attorney).
• Holding costs during rehab: If using hard money or a bridge loan, budget the monthly payments for the rehab period (typically 2 to 4 months).

The deeper the discount on purchase, the more likely you are to pull all your capital out at refinance. This is why BRRRR investors are the most aggressive negotiators in real estate. Every dollar saved on acquisition is a dollar that comes back to you at refinance.

Step 2: Rehab analysis

BRRRR rehab is different from flip rehab in one critical way: durability. When you flip a house, you are renovating it to sell. Premium finishes photograph well and help the listing. When you BRRRR, you are renovating it to rent. Every surface, fixture, and appliance needs to survive tenant use.

A moderate rehab is typical for BRRRR: $20 to $30 per square foot. This covers new flooring (LVP, not hardwood), painted cabinets or mid-grade replacements, new countertops (quartz or butcher block, not marble), updated bathrooms, fresh paint throughout, and updated fixtures and hardware. You want the property to look clean, modern, and rental-ready without over-finishing. See our full repair estimation guide for detailed cost breakdowns by category.

Add 10 to 15% contingency to your rehab estimate. The same principles apply as with flips: things go wrong, contractors run late, and hidden issues surface once you open walls. Budget for it upfront.

Step 3: Rental analysis

Once the property is renovated, what will it rent for? This is your After Repair Rent (ARR). Run rental comps the same way you run sale comps: same neighborhood, similar size and configuration, recently leased, similar condition. See how to run comps for methodology.

Calculate your projected monthly cash flow using the post-refinance mortgage payment:

• Gross monthly rent: Your ARR number.
• Mortgage payment: Based on the refinance loan amount, interest rate, and term (typically 30-year fixed).
• Property taxes: Monthly prorated amount.
• Insurance: Landlord/rental property policy.
• Property management: 8 to 10% of rent if you are not self-managing.
• Maintenance reserve: Budget 5 to 10% of rent for ongoing maintenance.
• Vacancy reserve: Budget 5 to 8% of rent (roughly one month vacant per year).
• CapEx reserve: Budget 5% for major capital expenditures (roof, HVAC, water heater).

Net cash flow = gross rent minus all expenses. If cash flow is negative after the refinance, the deal does not work as a BRRRR regardless of how good the refinance numbers look. You cannot subsidize a property out of pocket every month and call it an investment.

Step 4: Refinance analysis — the key step

This is what separates BRRRR from every other strategy. The refinance is where you recover your capital and turn a finished project back into deployable cash.

The math is simple but unforgiving:

• Appraised value (ARV): What the property appraises for post-renovation.
• LTV ratio: Your lender's maximum loan-to-value. Typically 75% for investment properties.
• Maximum loan amount: ARV x LTV. Example: $180K ARV x 75% = $135K loan.
• Capital recovered: Loan amount minus any existing debt on the property. If you paid cash, the full loan amount comes back to you.
• Capital remaining in deal: All-in cost minus capital recovered. This is the number that determines whether you can repeat.

The goal of every BRRRR deal is $0 left in the deal after refinance. That means your all-in cost must be at or below 75% of ARV.

Note the hard constraint: if you are all-in at $130K and the property appraises at $180K, you can borrow $135K and get all your money back plus $5K. But if the property only appraises at $165K, you can only borrow $123,750, leaving $6,250 trapped in the deal. The appraisal is the bottleneck.

Seasoning requirements

Most conventional lenders require a seasoning period before they will refinance based on the appraised value. This means you must own the property for 6 to 12 months before the lender will use the current market value instead of your purchase price. During this seasoning period, you are holding the property with your initial financing (cash or hard money), which adds to your carrying costs. DSCR lenders and some portfolio lenders have shorter or no seasoning requirements, but they often charge higher rates. Factor this into your timeline and holding cost projections.

Step 5: Repeat analysis

If you successfully pull all your capital out, you have the same amount of money you started with (or more) and you own a cash-flowing rental property. You can immediately deploy that capital into the next BRRRR deal. This is the compounding engine.

If money is left in the deal, calculate your cash-on-cash return on the trapped capital:

Cash-on-cash return = (Annual cash flow / Capital remaining in deal) x 100

If you have $10K remaining and the property cash flows $250/month ($3,000/year), your cash-on-cash return is 30%. That is still excellent, even though you did not achieve a full capital recovery. The question is whether that $10K earns a better return here or in a new deal. For most investors, 30% cash-on-cash on trapped capital is worth keeping.

Full worked example

Let's run a complete BRRRR analysis on a 3 bedroom, 2 bathroom, 1,200 sqft property in a B-class neighborhood.

Acquisition

• Purchase price: $100,000 (cash)
• Closing costs: $2,000 (2%)
• Total acquisition: $102,000

Rehab

• Moderate rehab at $25/sqft: $30,000
• Scope: Kitchen update, both bathrooms, LVP flooring throughout, paint, fixtures, landscaping
• Timeline: 2.5 months
• Holding costs during rehab: $650/month x 3 months (rounded up) = $1,950

All-in cost: $102,000 + $30,000 + $1,950 = $133,950

Rent

• After-repair rent (ARR): $1,600/month based on 4 rental comps within 0.5 miles
• Gross annual rent: $19,200

Refinance

• Appraised value (ARV): $180,000
• LTV: 75%
• Maximum loan: $180,000 x 0.75 = $135,000
• Capital recovered: $135,000 (paid cash, no existing mortgage)
• Capital remaining in deal: $133,950 - $135,000 = -$1,050 (you get $1,050 MORE than you invested)

Post-refinance cash flow

• New mortgage: $135,000 at 7.0% over 30 years = $898/month
• Property taxes: $225/month
• Insurance: $100/month
• Property management (8%): $128/month
• Maintenance reserve (5%): $80/month
• Vacancy reserve (5%): $80/month
• CapEx reserve (5%): $80/month

Total monthly expenses: $1,591

Monthly cash flow: $1,600 - $1,591 = $9/month

That is thin cash flow. Almost break-even. But consider what you actually have: a property worth $180,000, a tenant paying the mortgage, $0 of your own money in the deal, and $135,000 back in your pocket ready for the next purchase. Over time, as rents increase (even 3% annually, $1,600 becomes $1,648 next year), cash flow improves while your mortgage stays fixed. And you have not spent a dollar of your original capital.

Cash-on-cash return: infinite (no capital in the deal).

Repeat with the $135,000 you pulled out. If you do this three times in a year, you own three properties worth $540,000, with cash flow growing annually, and you have deployed the same $135,000 each time.

When BRRRR does not work

BRRRR is not a universal strategy. It fails in specific, predictable ways. Knowing when it does not work is as important as knowing how to execute it.

The ARV does not support a full capital recovery

Using the same example, but assume the property only appraises at $155,000 instead of $180,000. Refinance at 75% = $116,250. Capital remaining = $133,950 - $116,250 = $17,700 trapped. Your mortgage payment drops to $773/month, so cash flow improves to $227/month ($2,724/year), giving you a 15.4% cash-on-cash return on the trapped capital. Still good, but you cannot fully repeat because $17,700 of your capital is locked up.

Rents do not cover the refinanced mortgage

If the property only rents for $1,300/month instead of $1,600, your monthly expenses ($1,591) exceed your income. You are paying $291 out of pocket every month to hold this property. That is $3,492 per year of negative cash flow. The BRRRR math technically works (you pull your capital out), but you are subsidizing the property indefinitely. This is not an investment. It is a liability.

Interest rates are too high

At 7%, the $135K mortgage costs $898/month. At 8.5%, it costs $1,038/month. That $140 difference eliminates your cash flow entirely and then some. High-rate environments make BRRRR harder because the refinance creates a larger monthly obligation. You need either deeper discounts on purchase, higher rents, or both.

The property does not appraise as expected

Appraisers use their own comp selection, and they tend to be conservative. If your ARV was based on the highest comps in the neighborhood and the appraiser uses the middle or low comps, your refinance amount drops. A $15K to $20K appraisal shortfall is not unusual. Build this possibility into your analysis by using conservative ARV estimates. If the deal only works at the highest possible ARV, it does not work.

Common BRRRR mistakes

• Over-estimating ARV. Your optimistic comps are not the appraiser's comps. Use conservative comparables and expect the appraisal to come in 5 to 10% below your estimate. If the deal still works at 90% of your ARV, it is solid.
• Under-budgeting rehab. Same as with flips, but the consequences are worse. In a flip, a rehab overrun reduces your profit. In a BRRRR, a rehab overrun increases your all-in cost, which means more capital trapped after refinance. A $5K rehab overrun directly translates to $5K more of your money stuck in the deal.
• Ignoring seasoning requirements. If your lender requires 6 months of seasoning, you need to hold the property for 6 months before refinancing. That is 6 months of hard money payments or 6 months of capital tied up. Factor this into your holding cost and timeline projections.
• Forgetting to analyze cash flow post-refinance. Some investors get so focused on the capital recovery that they ignore what happens after. A fully recovered BRRRR that loses $200/month is not a success. It is an asset that costs you money every month until you sell it.
• Using the purchase price for the refinance calculation. The refinance is based on the appraised value, not your purchase price. If you bought a $180K property for $100K, the lender is lending 75% of $180K, not 75% of $100K. This is the entire reason BRRRR works. If lenders only lent against purchase price, the strategy would be impossible.

BRRRR is the most powerful wealth-building strategy in residential real estate when executed with discipline and accurate analysis. The five-step framework above gives you a systematic way to evaluate every potential deal. If the numbers work at conservative estimates, move fast. If they only work on optimistic assumptions, pass and find the next one. The beauty of BRRRR is that your capital recycles. One good deal leads to the next, and the next, and the next.
