Here's a deal we did in 2013. We bought two small houses on one multifamily-zoned lot for $121,000, put about $31,000 into renovations, and refinanced. That refinance paid back our lender and dropped our own cash in the deal to zero. A year later we pulled $50,000 out with a line of credit to buy another property. Years after that, we refinanced again and put $180,000 of tax-free cash in our pocket for the next deal. Today that property has over $300,000 in equity, has paid us more than $260,000 in distributions, and still cash flows every month.
We never had a large amount of our own money tied up in it. That's the entire promise of BRRRR.
What BRRRR actually is
BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. Investors coined the term, but the idea is old. Ten years ago we just called it the zero-down rental strategy.
The mechanics: you buy a property that's undervalued, usually because it needs work, renovate it to push up both its value and its rent, lease it to a tenant, then refinance based on the new appraised value. Done right, the refinance hands you back most or all of the cash you put in, and you carry it straight into the next deal. You're left with a cash-flowing rental, real equity, and very little of your own money trapped inside.
I got into this out of necessity. When I started in 2009, in the teeth of the worst recession since the Depression, I didn't have much to invest. Everyone told me prices were falling and I was crazy. I saw discounted properties, and the ugliest ones were the best deals. The only problem was financing those ugly properties, and BRRRR was the answer.
The four pieces you need
You can't run this strategy alone. You need:
- A hard money lender willing to fund the purchase plus the renovation. Some will collateralize your bank account or another property for security and release it at payoff.
- A conventional lender who will do a rate-and-term refinance with no seasoning requirement. Seasoning is when a lender insists on six months of ownership before they'll use the new appraised value. Find one who doesn't, or you'll wait.
- A contractor who works fast, because you're paying hard money interest the entire time.
- An investor-savvy agent who can estimate the after-repair value (ARV), so you know going in whether it will appraise where you need it to.
The financing side of this connects directly to everything in how to finance a rental portfolio with other people's money, which covers hard money, private lenders, and the refinance options in depth.
The refinance math that makes or breaks it
This is where deals are won or lost, so know the numbers cold:
- Rate-and-term refinance: 80% LTV on a single-family, 75% on a 2-4 unit. No seasoning if you funded with hard money. Pays off your loan but won't hand you back more than you owe.
- Cash-out refinance: about 5% lower (75% single-family, 70% on 2-4 units), and it requires six months of seasoning. This is the only one that can pay you back extra.
A simple example: hard money loan of $125,000, new appraised value of $200,000. A rate-and-term refinance allows up to $150,000 on a single-family. You can leave the new loan at $125,000 (plus rolled-in costs) or cash out the difference. The closer your finished value lands above what you're into the deal, the more of your cash comes home.
Case study: the Chattanooga duplex
Let me walk through a real one, because the numbers teach more than theory.
In late 2019 we sold a new-construction duplex we'd built in Everett. We'd intended it for a supported-living provider who backed out, so we rented both sides to regular tenants at $2,400 each, which still cash flowed about $900 a month. But I worried that $2,400 rent wasn't recession-proof, so we sold and rolled the gains into a 1031 exchange to buy more affordable units.
On the final day of our 45-day 1031 identification window, I was in Costa Rica. A self-storage deal we'd been counting on had just fallen through, and we needed to identify replacement property fast or pay tax. Our Chattanooga agent dropped two duplexes on our deal list that day. Asking was $149,900. We offered $140,000 cash, won over two other offers on the strength of a quick close and no financing contingency, and sent the address to our 1031 intermediary.
One side rented for $500, the other was vacant. Estimated fair-market rent was $750 a side. I underwrote it with $10,000 in renovations and a $155,000 ARV, before anyone had even been inside, running the numbers and pulling neighborhood data with DoorProfit. (It's fine to estimate conservatively and verify later.)
The inspection turned up foundation settling, a dead HVAC unit, electrical issues, and cosmetics. Bids came in at $6,500 for the renovation plus $4,000 for a new HVAC. We negotiated a $9,500 seller credit, dropping our final price to $130,500. We closed in early January with a mobile notary at our house in Washington, having never set foot in Chattanooga, trusting the agent, property manager, inspector, and contractor.
A detail I love: granite countertops are common where I'm from but rare in Chattanooga, so the contractor suggested butcher block. I'd never have considered it, and it looked great for a fraction of the cost. Local knowledge matters.
After renovation, our property manager raised the existing tenant from $500 to $830 (including $30 pet rent) and leased the vacant side in two weeks for $935. That's $1,765 a month, $265 more than I'd projected. The refinance appraisal came in at $155,000 (I'd hoped for $165,000). As a cash-out at 70% LTV, we got $108,500 back and left $32,500 in the deal at a 4% rate, for a 24% cash-on-cash return. We didn't fully BRRRR it because the appraisal came up short, but the deal still worked beautifully, and it deferred a tax bill on top.
The lesson buried in that story: even when BRRRR doesn't go perfectly, a well-bought value-add deal still wins. The whole due diligence process I ran on it is in the due diligence playbook.
Why I flip rentals instead of houses
I've flipped more houses than I can count, from carpet-and-paint jobs to down-to-the-studs rebuilds. Years ago I drew a line: no more flipping houses to sell. Only flipping rentals.
Here's why. Flipping to sell is a speculator's game. A hard money lender friend of mine, running $350 million in loans, once asked me how many flips out of ten break even or lose money. I guessed three. He said seven. Seven out of ten. On top of that, flip several houses a year and the IRS may treat you as a dealer, taxing the profit at ordinary income rates instead of capital gains. And there's liability, those after-closing calls when something breaks and everyone points at the flipper.
BRRRR is the better version of the same skill. You buy a property that needs work, renovate it on mid-grade rental finishes, rent it, refinance to get most of your cash back, and now you own a cash-flowing asset, not a one-time payday. Want to sell in a year for a profit anyway? Fine, just 1031 the gain forward. That's exactly how we built our portfolio.
How not to lose money doing this
In 13 years across dozens of flips and spec builds, I've lost money on exactly one property, a flip, where I dropped $19,000. (I sold it for $170,000 eight years ago; it's worth $300,000-plus today. Ouch.) Here's what that and a few underwater 2007-2009 purchases taught me:
- Walk away from bad deals. Real estate is one of the few investments that can cost you money every single month if you buy wrong. Disappointing in the moment, but walking is a win.
- Follow your due diligence checklist every time. When I rush and skip it, I always miss something, an inspection, a sewer scope, a late-paying tenant on the rent roll, and pay for it later.
- Buy for the long term and think like an asset manager. My underwater 2008 properties would have lost a fortune if I'd sold. Instead I raised NOI and sold years later into recovery, at a profit.
- Demand multiple exit strategies. Never buy a property that only works in one scenario. A flip that also pencils as a rental. A duplex you could condo and sell separately. I won't even buy a primary residence unless it would break even as a rental. This is one reason I favor 2-to-4-unit properties, which give you the most ways to win.
- Build your team by referral. Agents, property managers, contractors, lenders, 1031 intermediaries. A pre-existing relationship dramatically lowers your odds of getting taken.
The takeaway
BRRRR isn't a trick. It's a discipline: buy below value, force the value up, rent it, and refinance to free your capital for the next one. The math has to be honest, the team has to be real, and some deals will come up short on the appraisal like my Chattanooga duplex did. But get the pieces right and you can build a portfolio where your money does the work two, three, four times over instead of getting buried in a single down payment.
Run the numbers on your next deal both ways: as a flip you sell, and as a BRRRR you keep. Then ask which one is still paying you in ten years.
