What Is the BRRRR Method?
BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. You acquire a distressed property below market value, renovate it to increase its value, place a tenant, then refinance based on the new appraised value. If the numbers work, the refinance returns all or most of your original capital — which you then deploy on the next deal.
The wealth-building power of BRRRR is capital recycling. Instead of tying up $50,000 in a down payment permanently, you pull it back out and use it again. Done correctly, one pool of capital can fund multiple properties. Done incorrectly, your capital is stuck in a property with no exit.
The BRRRR Formula
The core question in any BRRRR analysis is: will the refinance return my capital?
Step-by-Step Math
- Step 1 — Total cash invested: Purchase Price + Rehab Costs + Closing Costs + Holding Costs
- Step 2 — Refinance proceeds: ARV x the lender's maximum LTV (75% is a common cap on investment refinances; confirm yours)
- Step 3 — Capital left in deal: Total Cash In minus Refinance Proceeds
The goal is Capital Left In = $0 or as close to it as possible.
Example Deal
- Purchase price: $95,000
- Rehab: $35,000
- Closing and holding costs: $8,000
- Total cash in: $138,000
- ARV: $195,000
- Refinance at 75% LTV: $146,250
- Capital left in deal: $138,000 minus $146,250 = negative $8,250
That means you pulled out $8,250 more than you put in. That is a home run BRRRR deal.
The 5 Numbers You Must Get Right
1. ARV (After Repair Value)
This is the most important number in the entire analysis. If your ARV is wrong, everything downstream is wrong. Use recent comparable sales close to the subject, of the same property type and similar square footage. Adjust for condition, bed and bath count, and lot size. Overestimating ARV is an expensive mistake in BRRRR investing, because the refinance is sized from it.
2. Rehab Costs
Get a real contractor estimate, not a drive-by guess. Line-item your repair costs — roof, HVAC, plumbing, electrical, kitchen, bathrooms, flooring, paint, landscaping. Add a contingency buffer; many investors use 10 to 15%, so set the figure your own experience supports. Rehab often runs over.
3. Purchase Price
A common starting formula for a BRRRR Maximum Allowable Offer is: MAO = (ARV x 75%) minus Rehab Costs minus Closing Costs minus Desired Profit Buffer. The 75% stands in for your lender's refinance LTV, so confirm yours.
4. Post-Rehab Rental Income
Pull actual rental comps for the neighborhood. Your rental income drives the DSCR (Debt Service Coverage Ratio) that determines whether a lender will refinance the property. Many investment property lenders look for a DSCR of 1.25 or higher, meaning monthly rent of at least 1.25 times the monthly payment; confirm your lender's minimum.
5. Refinance Terms
Model your refinance at current DSCR loan rates, not the rate you hope for. DSCR loan rates move with the market, so get a quote rather than assuming a figure. Then run the numbers again at a rate above your quote to stress-test the deal.
Cash Flow Analysis After Refinance
A successful BRRRR is not just about getting your capital back — the property still needs to cash flow after the refinance.
Monthly Cash Flow = Gross Rent minus Mortgage Payment minus Property Tax minus Insurance minus Property Management (8-10%) minus Vacancy Reserve (8%) minus Maintenance Reserve (5-8%) minus Capital Reserve (roof, furnace and other long-lived items)
- Green light: Monthly cash flow at or above the figure you require, after a refinance at your lender's LTV (75% is a common planning assumption; confirm yours)
- Caution zone: Positive cash flow below the figure you require — works but leaves little margin for error
- Red light: Negative cash flow after refinance — reassess your purchase price or rehab budget
BRRRR Mistakes to Avoid
Over-Improving the Property
Granite countertops and luxury finishes do not always translate to higher ARV in B and C class neighborhoods. Match your rehab to the neighborhood standard. Over-improving can undercut your refinance math and eat into returns you may not recover.
Underestimating Holding Costs
A 6-month rehab timeline means 6 months of mortgage payments, utilities, insurance, and property taxes before you see a dollar of rent. Model this accurately or your deal analysis will be wrong from the start.
Assuming the Refinance Will Work
Lenders have seasoning requirements — many require you to own the property for 6 to 12 months before refinancing. Some require the property to be rented for a full lease cycle. Know your lender's requirements before you buy, not after.
Using Optimistic ARV
Your ARV must be defensible to an appraiser, not just to you. Use conservative comps and let the upside surprise you. An appraiser who comes in $20,000 below your projected ARV can unravel an entire BRRRR deal at the refinance stage.
How Appraize Models BRRRR Deals
Manually running all five BRRRR numbers on every deal is time-consuming and error-prone. Appraize models your BRRRR analysis automatically — ARV from real MLS comps, line-item repair estimates calibrated to your local market, refinance projections, and cash flow analysis after refinance.
Every BRRRR deal gets modeled alongside all 7 other exit strategies simultaneously. Sometimes a deal that looks marginal as a BRRRR is a strong fix and flip or buy and hold. Seeing all 8 exits at once means you never leave money on the table.
Analyze your next BRRRR deal at Appraize. Get ARV, repair estimates, and full BRRRR projections in under 30 seconds.
The Bottom Line
The BRRRR method is one of the most powerful wealth-building strategies in real estate. It is also one of the easiest to get wrong. Scaling a portfolio with BRRRR depends on running the numbers before you fall in love with a property.
Get your ARV right. Model your rehab accurately. Stress-test your refinance. Confirm cash flow after the refi. Do all of that before you make an offer and BRRRR becomes exactly what it promises — a repeatable system for building a rental portfolio without constantly deploying new capital.
