Short answer: You buy a property that needs work, rehab it, rent it, then do a cash-out refinance based on the higher after-repair value to pull out some or all of your cash, and repeat with the next property.
Definition
The BRRRR method is a rental strategy: buy a property that needs work, rehab it, rent it, refinance at the higher after-repair value to pull cash back out, and repeat.
By the numbers: Fannie Mae caps cash-out refinances of one-unit investment properties at 75% loan-to-value and 2–4 units at 70% (Eligibility Matrix).
What BRRRR means
BRRRR stands for buy, rehab, rent, refinance, repeat. You buy a property that needs work, fix it up, rent it out, then refinance based on the higher after-repair value (ARV). The new loan pays back some or all of your cash, which you reuse on the next deal.
It works only if the property is worth meaningfully more after the rehab than you spent in total. If the refinance doesn't return most of your cash, you've simply bought one rental with a lot of money tied up.
How much the refinance can return
The refinance is a cash-out loan on an investment property. On loans sold to Fannie Mae, the Eligibility Matrix caps cash-out refinances of investment properties at 75% loan-to-value for one unit and 70% for 2–4 units. Cash-out loans also carry loan-level price adjustments, so expect a higher rate than a purchase loan.
| 70% of $240,000 ARV | $168,000 loan · $26,540 left in |
| 75% of $240,000 ARV | $180,000 loan · $14,900 left in |
Rows use the example below: $189,500 all-in, with refinance closing costs assumed at 3% of the new loan.
The waiting rules
Fannie Mae's cash-out refinance rules (Selling Guide B2-1.3-03) set two clocks:
| Time on title | At least one borrower on title for 6 months before the new loan funds |
| Existing first mortgage | Must be at least 12 months old if the refinance pays it off |
So if you buy with a short-term or hard-money first mortgage, a Fannie Mae cash-out refinance generally has to wait 12 months from that loan's note date.
Good to know: Fannie Mae's delayed financing exception lets you refinance within six months if you bought with no mortgage financing, but the new loan is capped at your documented investment in purchasing the property (plus the new loan's closing costs). Ask your lender whether rehab costs count. DSCR and portfolio lenders set their own seasoning rules.
BRRRR traps
Red flag: An optimistic ARV. The refinance is based on the appraisal, not your estimate. If it comes in low, more of your cash stays stuck in the deal.
Rehabs also run over budget and over schedule, and every extra month means more holding costs and interest on any short-term loan. After the refinance, the property still has to cash-flow with the new, larger loan. Score it the way a lender sees it.
Worked example
Buy for $150,000 with $4,500 closing costs (3%, assumed), rehab for $35,000, then refinance at 75% of a $240,000 after-repair value. 30-year rate 7.40% (Freddie Mac average, October 15, 2026; cash-out investment rates are usually higher), $2,100/mo rent, $2,880/yr tax, $1,200/yr insurance. Illustrative numbers.
| All-in cost (buy + rehab + closing) | $189,500 |
| Refinance loan (75% of ARV) | $180,000 |
| Refinance closing costs (3%, assumed) | $5,400 |
| Cash left in the deal | $14,900 |
| New principal & interest | $1,246 |
Frequently asked questions
How does the BRRRR method work?
You buy a property that needs work, rehab it, rent it, then do a cash-out refinance based on the higher after-repair value to pull out some or all of your cash, and repeat with the next property.
How soon can you refinance a BRRRR property?
For loans sold to Fannie Mae, at least one borrower must be on title for six months, and an existing first mortgage being paid off must be at least 12 months old. A delayed financing exception allows earlier refinancing of properties bought without a mortgage, capped at the documented purchase investment. Other lenders set their own rules.
How much can you cash out on a rental refinance?
Fannie Mae caps cash-out refinances of investment properties at 75% loan-to-value for one unit and 70% for two to four units, based on the appraised value.
