BRRRR Explained With Real Numbers
You've got some cash, maybe $150,000 from savings or a HELOC, and you keep hearing that BRRRR investors buy a property, pull their money back out, and do it again on the same pile of cash. You want to know if that's actually how it works or if it's something people say on YouTube that falls apart once you run real numbers.
It's real. BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. You buy a property under market value, put money into fixing it, rent it out, then refinance based on the new higher appraised value instead of what you paid. If the refinance loan is big enough, it pays back most or all of the cash you put in. You keep the property, you keep the tenant, and your original cash is free to do the next deal.
The part people skip past is that step 4 only works if step 1 and step 2 were done right. The refinance doesn't create value. It just lets you access value you already built by buying cheap and fixing the property. Get the purchase price or the rehab budget wrong and there's no equity for the bank to lend against.
Why the Refinance Step Actually Returns Your Cash
A regular mortgage is based on the purchase price. A refinance is based on the appraised value at the time you refinance. That gap is the entire mechanism.
Say you buy a house for $100,000 and the bank would normally lend 75% against that, or $75,000. But you're not getting a purchase loan here, you already own it. After you put $40,000 into the rehab, an appraiser looks at the finished product and says it's worth $200,000. Now the bank will lend 75% of $200,000, which is $150,000. That's double what they'd have lent on the original purchase price, because the value the appraiser sees is what you built, not what you paid.
That $150,000 is what pays you back. Not profit. Reimbursement for the cash you already spent buying and fixing the property.
A BRRRR Deal With Real Numbers
Here's one version of the math, using round numbers so you can follow every step.
Buy: Purchase price $100,000. Closing costs, inspection, and a hard money origination fee add roughly $10,000. Cash out the door so far: $110,000.
Rehab: New roof, kitchen, bathrooms, flooring, paint. Contractor bid comes in at $40,000. You also carry the property for four months while work happens, covering interest on the hard money loan, insurance, and taxes, call that $10,000 more.
Total cash into the project: $110,000 + $40,000 + $10,000 = $160,000.
Rent: Once finished, the house rents for $1,800 a month. You've got a tenant signed.
Refinance: An appraiser values the finished property at $200,000, based on recent comparable sales in the area. Your lender offers a 75% loan-to-value refinance. $200,000 x 0.75 = $150,000 loan amount. Refinance closing costs run about $4,000, so you net $146,000 in cash back.
Repeat: You put in $160,000 and got $146,000 back. You've got $14,000 left in the deal, but you now own a $200,000 property with a tenant paying rent, and you've recovered 91% of your original cash. On the next deal, if the numbers are a little better or the rehab comes in a little cheaper, you can get all of it back or more.
On the monthly side: the new $150,000 mortgage at a 30 year fixed rate runs around $1,049 a month in principal and interest. Add taxes and insurance, call it $200 a month. Total payment near $1,249. Rent is $1,800. That's $551 a month before vacancy, repairs, and property management, which is what actually pays you while you wait for the next deal.
What People Get Wrong About BRRRR
The most common mistake is estimating the after repair value first and working backward to justify the purchase price. That's backward. The ARV has to come from actual recent sales of comparable finished properties in that specific area, not from what you hope the market will do. If you guess high on ARV, the refinance appraisal comes in lower than expected and you're stuck with more cash trapped in the deal than you planned for.
The second mistake is underestimating rehab cost. Contractors run over. Permits take longer than expected. A $40,000 budget that turns into $55,000 eats directly into the cash you get back at refinance, because the loan is based on value, not on what you spent.
The third mistake is not checking seasoning requirements before falling in love with the numbers. Most lenders won't refinance a property you've owned for less than six months, some want twelve. If your hard money loan matures before you hit the seasoning window, you're either extending an expensive short term loan or scrambling for a different lender. Check this before you buy, not after.
The Honest Limitation
BRRRR works when the math works, and the math doesn't always work. In a lot of markets right now, the spread between what a property costs to buy and rehab and what it appraises for after the work is too thin to get a meaningful amount of cash back out. You can do everything right on the construction side and still leave $30,000 or $40,000 sitting in the deal because the neighborhood's comparable sales don't support a high enough ARV.
That's not a reason to avoid BRRRR. It's a reason to run the numbers on the specific property before you buy it, not after. A deal that doesn't cash you out isn't necessarily a bad deal, it might still cash flow fine, but you should know that going in instead of finding out at the refinance appraisal.
If you're staring at a property right now trying to figure out whether the purchase price, rehab budget, and likely ARV actually leave you with cash back at refinance, that's exactly the calculation Deal Machine runs before you put any money down.
