The BRRRR Method Explained: Buy, Rehab, Rent, Refinance, Repeat
By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.
The BRRRR method means Buy, Rehab, Rent, Refinance, Repeat. You buy a property below its potential value, renovate it, rent it out, then refinance against the higher value to pull out some or all of your cash for the next deal. It works only when the purchase price, rehab budget, rent and refinance appraisal all line up.
The idea is simple. The execution is not. In Northern California, high prices, rental rules and current interest rates make the numbers tighter than many online examples suggest. This guide walks through each step, the lender rules that shape the refinance, and a sample calculation you can adapt.
How the BRRRR method works
- Buy a property that needs work, usually with cash, a hard money loan or a short-term bridge loan.
- Rehab it to rent-ready condition, focusing on repairs that raise value and rent.
- Rent it to a screened tenant at market rent.
- Refinance into a long-term loan based on the new appraised value, using the proceeds to repay short-term debt and recover cash.
- Repeat with the recovered capital.
The engine of the strategy is forced appreciation: the gap between what you paid plus rehab costs and what the property is worth after repairs. That after-repair value (ARV) drives every decision. Our guide to calculating after repair value covers how to estimate it from comparable sales.
Step 1: Buy at the right number
Many investors start from the “70% rule”: pay no more than 70% of ARV minus repair costs. Treat it as a screen, not a law. In expensive markets, deals at 70% are rare, and some investors accept 75% to 80% with more cushion elsewhere.
Where these properties come from:
- Bank-owned homes and short sales. See investing in REO properties for the process.
- Estates and long-held homes that need updating.
- Listings with stale photos, long days on market or deferred maintenance.
Financing the purchase: conventional lenders often will not lend on homes that are not habitable. Hard money and private loans fill the gap at higher rates and points. If you pay cash, keep the settlement statement and proof of funds, because they matter at refinance.
Step 2: Rehab with a budget and a timeline
- Get written bids and add a contingency of 10% to 20% for what opens up behind walls.
- Pull permits. Unpermitted work can hurt the appraisal and cause trouble with insurers and future buyers.
- Prioritize repairs that matter to tenants and appraisers: roof, systems, kitchens, baths, flooring, paint.
- Track every dollar. Holding costs (interest, taxes, insurance, utilities) add up each month the project runs long.
For older Bay Area and wine country homes, expect surprises in sewer laterals, electrical panels and foundations. Inspect before you buy, not after.
Step 3: Rent it under California rules
California’s Tenant Protection Act caps most rent increases at the lower of 5% plus inflation or 10% in a 12-month period, and requires just cause for evictions once a tenant has lived there 12 months. Single-family homes are generally exempt unless owned by a corporation or REIT, but the exemption depends on proper notice in the lease. Some cities add local rent control. Check local rules before you set rent.
Screen tenants consistently using written criteria, follow fair housing law, and document the condition of the unit at move-in. A lease and rent history also help at refinance, since many lenders count a portion of rental income when qualifying you.
Step 4: Refinance and the seasoning rules
This is where many BRRRR plans stall. Fannie Mae’s Selling Guide (updated December 2025) sets rules that shape conventional cash-out refinances:
- Six months on title. At least one borrower generally must have been on title for six months before the new loan funds.
- 12-month rule for existing loans. If the refinance pays off an existing first mortgage, that loan generally must be at least 12 months old.
- Delayed financing exception. If you bought with cash in the last six months, you may be able to refinance sooner, but the new loan is limited to your documented investment plus allowed closing costs.
Lenders also cap the loan-to-value on investment property cash-out loans, and the appraisal may come in lower than your ARV. Some investors use DSCR (debt service coverage ratio) loans from non-bank lenders, which qualify on rental income instead of personal income, at a higher rate. Talk to a lender about which path fits before you buy. Our financing page is a good starting point.
Step 5: Repeat, carefully
Each cycle adds debt. Before buying the next property, confirm that the last one cash-flows after the refinance, that you have reserves for vacancies and repairs, and that you are not over-leveraged if values or rents dip.
A sample BRRRR calculation
The numbers below are illustrative only, not a forecast for any property or area.
| Item | Amount |
|---|---|
| Purchase price | $520,000 |
| Rehab budget with contingency | $110,000 |
| Closing and holding costs | $40,000 |
| Total cash invested | $670,000 |
| Appraised value after rehab | $800,000 |
| Refinance at 75% loan-to-value | $600,000 |
| Cash left in the deal | $70,000 |
| Monthly payment at 7.32%, 30-year fixed | About $4,120 |
In this example, the investor recovers most of their cash, but monthly rent would need to cover about $4,120 in principal and interest plus taxes, insurance, maintenance and vacancy. That is why many California BRRRR deals recover capital but run close to break-even on cash flow. Run your own numbers with a lender and a tax adviser.
Pros and cons
| Advantages | Drawbacks |
|---|---|
| Recycles capital into more properties | Rehab overruns and delays |
| Builds equity through improvements | Appraisal may come in low |
| Long-term rental income | Higher-cost short-term financing |
| Rental depreciation (27.5 years for residential buildings under IRS rules) | Landlord duties and California tenant law |
BRRRR differs from a fix-and-flip strategy mainly in the exit: a flipper sells, a BRRRR investor holds and refinances. Selling within a year usually means short-term capital gains, taxed as ordinary income.
Questions people ask
Does BRRRR still work with rates above 7%?
It can, but the margin is thinner. Higher rates reduce how much rent covers after the refinance, so the purchase discount and rehab value need to be larger.
How soon can I refinance after buying?
Under Fannie Mae rules, generally after six months on title, unless you qualify for delayed financing after a cash purchase. Other loan programs set their own waiting periods.
Can I use BRRRR on a multi-unit property?
Yes. Two- to four-unit buildings are common BRRRR targets, but they may fall under the Tenant Protection Act and local rent rules.
What is the biggest risk?
A low appraisal at refinance, which can leave more of your cash stuck in the property than planned.
