The BRRRR Strategy: Buy, Rehab, Rent, Refinance, Repeat

BRRRR means buying a property that needs work, renovating it, renting it out, and then refinancing at the higher after-repair value to pull your cash back out for the next purchase. The refinance decides whether that works. Under Fannie Mae's rules, a cash-out refinance on a one-unit rental can be no more than 75% of the new appraised value (70% for two to four units), one borrower must have been on title for six months, and any first mortgage the new loan pays off must be at least 12 months old. To get all your cash back, your purchase price, closing costs, rehab, and holding costs together must come in under 75% of the appraised value, minus the refinance's own closing costs.

How the five steps work

1. Buy. Look for a property whose price plus rehab leaves room under the after-repair value (ARV), the value an appraiser is expected to give once the work is done. Base your ARV on recent sales of similar renovated homes nearby, not on listing prices. You can pay cash or use a short-term hard money loan, and that choice sets when you can refinance.
2. Rehab. At a 75% refinance, each $1,000 the work adds to the appraised value raises the new loan by $750, so overruns and work that does not raise the value stay in the deal. Pull permits and keep invoices and before-and-after photos to support the appraisal, and confirm that your insurance covers a vacant house under renovation. Taxes, insurance, utilities, and any loan interest run every month until the refinance closes.
3. Rent. Before you apply, sign a 12-month lease at market rent and keep records showing you deposited the tenant's security deposit and first full month's rent, which Fannie Mae accepts as evidence that a new lease is in effect. The lender must document your current primary-residence housing payment before using this property's rental income; if you live rent-free with no qualifying housing payment, the rent cannot offset the rental property's payment. When a lease may be used to calculate rental income, the lender counts 75% of the rent minus the full new payment in your debt-to-income ratio (DTI), your monthly debts divided by your gross monthly income, and adds a negative result to your debts. Ask which Fannie Mae rental-income policy your lender uses: the September 2026 changes are mandatory for applications dated December 1, 2026 or later, but lenders may adopt them earlier. Under the earlier policy, documented partial-year rental or renovation cases may qualify using a current lease even if the property appears on Schedule E of your latest tax return. Under the updated policy, the lender uses Schedule E for properties listed there, averaging over the months rented when a documented partial-year or renovation exception applies, and may add back documented one-time property expenses. If you have less than 12 months of experience managing rentals, a positive result can only offset the property's own payment. A DSCR loan, named for the debt service coverage ratio, instead qualifies the property on its rent divided by its payment.
4. Refinance. Replace the purchase money with a long-term loan sized on the new appraised value, not on what you spent. You also need cash reserves, savings left after closing, equal to six months of the new payment (about $11,950 for the 75% loan in the example below), and Fannie Mae does not count the cash-out proceeds toward them.
5. Repeat. Use the returned cash for the next purchase. Fannie Mae allows up to 10 financed properties, counting your home if it has a mortgage, for a rental loan approved through its Desktop Underwriter system. Each later loan needs six months of its own payment in reserves plus 2% to 6% of the balances on your other financed rentals, so not all of the recovered cash can go to the next down payment. Past 10 properties, you would need a DSCR loan or a portfolio loan (one the lender keeps instead of selling), which rental property financing options compares.

How much cash the refinance returns

Here is a one-unit house bought with cash and refinanced after six months:

If the appraisal comes in at $250,000, the 75% loan falls to $187,500 and $23,500 of your cash stays in; each $1,000 of shortfall leaves $750 more in the property. If you think the value is wrong, you can ask the lender for one reconsideration of value per appraisal before closing, with up to five comparable sales and an explanation of what the report got wrong.

Fannie Mae also charges lenders risk-based fees, called loan-level price adjustments, which they pass on to you through the rate or upfront points. For a 75% cash-out loan on a rental with a credit score of 760 to 779, the fees total 3.375% of the loan (1.25% for the cash-out plus 2.125% for the investment property), about $7,088 on $210,000. At 65% of value, they total 2.5%.

When you can refinance

Fannie Mae's timing rules depend on how you bought:

• Paid cash: A standard cash-out refinance is available once you have been on title for six months. Before then, the delayed financing exception lets a cash buyer refinance if the purchase was between unrelated parties and you can document that no mortgage was used, but the new loan is capped at your documented purchase cost plus closing costs. In the example, that returns about $154,000 instead of $204,000, and because the new loan is a first mortgage, it must be 12 months old before a later cash-out refinance can pay it off.
• Used a hard money loan: The loan being paid off must be at least 12 months old, counted from the date it was made to the date of the new loan. On a $180,000 hard money balance at an assumed 11% interest-only rate, each month costs $1,650, about $450 more than the same balance at the 8% long-term rate used below, so waiting six extra months costs about $2,700 more in interest. Before 12 months, a limited cash-out refinance can replace the hard money loan with a long-term one, but it returns little or no cash.
• Bought in an LLC: Time the property was held by an LLC you control counts toward the six months, but the property has to move into your own name before the refinance closes.
• Refinancing with a DSCR loan: DSCR lenders set their own waiting periods. Before you buy, ask how many months you must own the property before the lender will use the new appraised value instead of your cost, and get the answer in writing.

Refinancing an investment property covers rate-and-term and cash-out refinances outside a BRRRR plan.

Cash flow after the refinance

Taking out the maximum raises the payment, and at late-2026 rates it can leave little or no cash flow. Freddie Mac's weekly average 30-year rate was 7.32% on October 22, 2026, but that survey covers owner-occupied purchase loans, so this example assumes 8% on a 30-year fixed cash-out loan for a rental. Rent is $2,600, taxes and insurance are $450 a month, and 23% of rent ($598) is budgeted for vacancy (5%), repairs and replacements (10%), and management (8%):

The 75% loan returns nearly all your cash but leaves only about $130 a year to absorb any vacancy or repair beyond the budget, and the lender adds its -$41 to your monthly debts. The 65% loan leaves $29,000 in and nets about $2,600 a year, a 9.0% cash-on-cash return on the cash still in the deal. Run both versions before you choose a loan amount; how to buy your first rental property covers the purchase steps if this is your first rental.
