The BRRRR Method, Step by Step
BRRRR — Buy, Rehab, Rent, Refinance, Repeat — is a strategy for recycling the same pool of cash into several rental properties instead of tying it up permanently in one. Done well, it lets you pull most of your original investment back out through a refinance and use that same cash on the next deal. Done poorly, it leaves you over-leveraged on a property that does not cash flow. The difference usually comes down to whether the numbers were conservative at every step, not just at the purchase.
The five steps
Buy
The target is a property priced below its after-repair value by enough to cover the rehab and still leave equity. A common screen is that purchase price plus rehab budget should land meaningfully under 70-75% of after-repair value — the same logic flippers use, adjusted for the fact that you are refinancing rather than selling.
Rehab
Renovate to a standard that supports both the value you underwrote and the rent you projected. This is where BRRRR deals most often go over budget, and an overrun does not merely eat profit — it directly shrinks the equity the refinance depends on.
Rent
Get the property occupied at or near the rent you underwrote, ideally before you refinance. Lenders generally want a signed lease or an appraiser's market rent opinion to qualify the refinance, and an unrented property is a harder refinance in most cases.
Refinance
Take out a new loan — often conventional or a DSCR loan — based on the property's appraised value after the work, not on what you paid. The new loan repays whatever financed the purchase and rehab, and what is left over is cash back in your hands.
Repeat
Use the recovered cash toward the next property. This is the step that makes BRRRR a strategy rather than a single transaction: the same capital cycles through several deals over time.
Where the numbers actually come from
These figures are illustrative — a teaching example, not market data for any particular city.
| Purchase price + closing | $143,500 |
| Rehab budget | $35,000 |
| Total cash invested (incl. holding costs) | $62,000 |
| After-repair value (ARV) | $230,000 |
| Refinance loan (75% LTV) | $172,500 |
| Payoff of initial financing | $129,150 |
| Cash pulled out at refinance | $38,850 |
| Cash left in the deal | $23,150 |
Two things in that table are worth naming, because the figures alone do not explain themselves. The $129,150 payoff is 90% of the purchase and closing total, so the initial financing covered 90% and the investor's own money went in as the remaining 10% plus the rehab plus the carrying costs during the work — which is how $62,000 of cash gets committed on a $143,500 purchase. And the refinance does not hand over the full $43,350 difference between the new loan and the payoff: about $4,500 of it goes to refinance closing costs, leaving $38,850.
So the investor recovers $38,850 of $62,000 — about 63% — and $23,150 stays in the property. That is still a strong outcome if the property cash flows on the new mortgage. "Infinite return" deals, where all of the cash comes back, do happen, but they require the spread between purchase-plus-rehab and after-repair value to be unusually wide, and they are the exception rather than the baseline to plan around.
The appraisal is the whole deal
Everything downstream of the refinance rests on one number nobody can confirm until an appraiser says so. At $230,000 the new loan is $172,500 and $38,850 comes back. If the appraisal lands 10% lower, at $207,000 — not a disaster, just an ordinary outcome — the loan falls to $155,250, the cash returned drops to $21,600, and the money stranded in the deal nearly doubles from $23,150 to $40,400.
The deal has not failed. It has simply stopped being the deal you modeled, and the capital you were going to put into the next property is not there. This is why the after-repair value deserves more scrutiny than any other input: it should come from closed sales of comparable renovated properties, not from active listings, and certainly not from adding your purchase price to your rehab budget — that is a cost, not a value.
Seasoning: the step that catches people out
Most lenders apply a seasoning requirement — a minimum period you must have owned the property before they will lend against its new value rather than against what you paid. A BRRRR modeled on a six-month timeline and financed by a lender who wants twelve months of seasoning has a funding gap in the middle, and the expensive short-term loan keeps accruing through the whole of it.
Ask about it before you buy, not after the rehab. Requirements differ between lenders and between loan programs at the same lender, and the answer determines whether your timeline is realistic or merely hopeful.
The refinance has to pass two tests, not one
Value is the first test and income is the second. A lender sizing the new loan at 75% of appraised value will also check that the rent supports the payment — on an investment property that usually means a debt service coverage ratio, the rent measured against the full monthly obligation.
A property can appraise beautifully and still fail that second test if the rent is thin relative to the larger loan, which leaves you refinancing less than the value supports. Run the post-refinance numbers through the DSCR loan qualifier before you commit to the purchase, because the exit you are counting on is underwritten by somebody else.
Rate risk between buying and refinancing
You buy on one set of rates and refinance on another, with months in between. A refinance rate half a point above what you underwrote raises the payment on the new loan permanently, and because the loan is sized off value rather than off cash flow, nothing about the refinance amount adjusts to compensate — the whole difference lands on your monthly cash flow.
The defence is to underwrite the refinance at a rate above today's quote and see whether the deal still works. If it only works at the rate you can get right now, the plan has no margin for a delay you do not control.
Where it goes wrong
- Rehab overruns. Every dollar over budget is a dollar that does not come back out at the refinance.
- Appraisal risk. The refinance is based on the appraiser's opinion, not your estimate — and a conservative one strands capital, as the figures above show.
- Seasoning mismatch. A timeline built on six months against a lender wanting twelve is an expensive gap.
- Rate risk. The refinance payment is set months after you commit to the purchase.
- Failing the income test. Value qualifies the loan; rent qualifies it too, and the second one is easier to overlook.
- Judging it only on cash recovered. A deal optimized purely for getting your money back produces a property carrying the largest loan it can — which is also the one with the least cash flow.
When BRRRR is the wrong tool
The strategy earns its complexity when the spread between what a property costs to buy and fix and what it is worth afterward is genuinely wide. Where that spread is thin, you are taking on construction risk, financing risk, appraisal risk and timeline risk to end up owning a property you could have bought outright with less drama and a smaller loan.
It is also the wrong tool if your plan depends on recovering all of your capital. Treat full recovery as upside rather than the base case, model the version where the appraisal disappoints, and ask whether you would still want to own the property at the end of it. The BRRRR calculator runs the whole sequence including the post-refinance cash flow, and the rental analyzer answers the question that matters once the dust settles: would you buy this property, at this loan balance, if you were seeing it for the first time?
