The BRRRR Infinite Return: Leaving No Cash in the Deal, and Whether It Is Realistic

An infinite return is what a BRRRR investor calls the position where the refinance returned every dollar of cash invested and the property still pays a positive cash flow. The return on the cash left in the deal is cash flow divided by zero. It is real, it is achievable, and it is less common and less free than it sounds.

What it takes

Cash out has to equal or exceed cash invested. Since the refinance pays off the short-term loan, that condition simplifies to:

Refinance loan × (1 − refinance closing %) ≥ total project cost

With a 75% refinance and 3% closing costs, total project cost has to be at or below 72.75% of ARV. Total project cost includes the soft costs, which on a hard money deal with a six-month hold run 5 to 6% of ARV. So purchase plus rehab has to come in around 67% of ARV.

On a $260,000 ARV with $40,000 of rehab, that is a purchase price of about $135,000. The 70% rule would say $142,000. The difference, $7,000, is roughly what stays in the deal at the 70% rule price. The 70% rule guide covers why.

How often it happens

Distressed property that sells at 52% of its finished value exists, but it is not on the MLS at that price for long, and the properties that reach it usually need the full $40,000 of work or more. Investors who report consistent full-recovery BRRRRs are typically buying off-market, doing heavier renovations, or working in markets where the gap between distressed and finished values is unusually wide.

Many successful BRRRRs recover 60 to 90% of the cash. The default deal in the calculator recovers 76%, leaving $16,675 in a property worth $260,000. That is a rental bought with a 6% down payment, and it earns 7.4% on the cash left. It is a good outcome that would not make a headline.

Why zero cash in is not free

The cash came back because a lender wrote a larger loan. The loan has a payment. An infinite return on a property that clears its mortgage by $50 a month is $600 a year of income on an asset you now manage, insure and repair. The return is infinite and the dollars are small.

The equity is also thinner than it looks. At full recovery you own a property at 75% LTV with 25% equity, all of it created by the discount and the renovation. That equity is real, but a 10% market decline takes 40% of it.

And the cash that came back is borrowed at the refinance rate. Deploying it into the next deal is the point of the strategy. Spending it is taking a cash-out loan against a rental.

The test that matters more

Cash flow on the new loan. A deal that returns every dollar and loses $150 a month is not an infinite return. It is a property that costs you $1,800 a year and holds none of your equity capital. A deal that leaves $20,000 in and earns $3,000 a year is a 15% return and a property that pays for itself.

The calculator shows both figures because both matter. The cash left in tells you what the deal cost. The cash flow tells you what it earns. The infinite return only exists when the second number is positive.

Reading a deal that leaves cash in

Treat the cash left in as the down payment on a rental, and judge the rental.

• Cash on cash on what remains: 8% or better is good, 12% or better is excellent, and both are common on partial-recovery BRRRRs because the denominator is small.
• DSCR on the new loan: 1.2 or better means the rent covers the payment with room. Under 1.0 means you are subsidizing it.
• Equity created: ARV minus total project cost. On the default deal that is $54,175, which is the reward for the work regardless of how much cash came back.

A BRRRR that leaves 20% of the cash in and produces those three numbers beat most turnkey purchases on every measure. The BRRRR vs buy and hold guide runs the comparison.

When more than 100% comes back

If the appraisal is strong enough that the refinance loan exceeds total project cost plus refinance costs, you leave closing with more cash than you put in. On the default deal an ARV of about $300,000 would do it, returning around $12,000 more than invested.

That surplus is loan proceeds. It is not taxed as income, because it is borrowed. It is also not profit. It is a larger mortgage on the same property, and the payment reflects it. Investors who treat the surplus as a windfall rather than as capital for the next deal tend to find the rental thinner than they expected.

Underwriting for it

If full recovery is the goal, use the calculator’s “max purchase price” solver with stressed inputs: ARV 5 to 10% below your estimate, rehab 15% above the bid, a longer hold, and the lender’s real LTV. The price that returns all cash under those assumptions is the offer. It will be lower than the 70% rule and much lower than the asking price, and most of your offers will be declined. The ones that are accepted are the ones the strategy was built for.

The risks guide prices each of the stressed inputs, and the ARV pages show the full-recovery purchase price at every after-repair value from $150,000 to $1 million.
