BRRRR: The Setup
BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. Most people think the Buy phase requires either cash or a hard money loan. It does not. The Buy phase can be a seller-financed note - often with better terms and more flexibility than hard money.
Here is why that matters: Hard money costs 10-14% interest plus 2-3 points, due in 6-12 months. A seller-financed note might cost 5-6% with a 5-year balloon. That difference in carrying cost changes your entire rehab budget math.
The Hybrid SF-BRRRR Structure
Instead of the classic BRRRR:
Cash/Hard Money - Rehab - Rent - Refi - Repeat
You run the SF-BRRRR version:
**Seller Financing (balloon) - Rehab - Rent - Refi - Repeat**
The seller is your acquisition lender. Their balloon date is your refi deadline. If you execute the rehab and stabilization on time, you refi at the new higher value, pay off the seller, and pull out your capital.
Worked Example - Single-Family Rental SF-BRRRR
Property: 3/2 SFR, beat up, off-market. Seller is a tired landlord, free and clear.
Offer:
- Price: $140,000
- Down: $10,000
- Seller note: $130,000 at 6%, 5-year balloon, 25-year amortization
- Monthly payment: $836/mo
Rehab:
- Budget: $35,000 (funded from cash reserves and short-term personal LOC)
- Timeline: 3 months
- Total in deal: $45,000 ($10K down + $35K rehab)
After-Repair Value (ARV):
- Comparable sales: $230,000-$240,000
- Conservative ARV: $225,000
Rent:
- Market rent after rehab: $1,650/mo
- Tenant placed in month 4
Refinance (Month 12):
- DSCR lender, 75% LTV: $225,000 x 0.75 = **$168,750**
- Pay off seller note balance (~$127,800): done
- Cash to you: $168,750 - $127,800 = **$40,950**
- You recover $40,950. Your net in deal: $45,000 - $40,950 = **$4,050**
You now own a $225,000 asset with a $168,750 DSCR loan and $4,050 out of pocket. That is a 98% recovery of invested capital.
Monthly cash flow after DSCR refi (7.5%, 30-year, $1,181/mo PITIA with taxes/insurance):
$1,650 - $1,181 = $469/mo
Why Seller Financing Beats Hard Money in BRRRR
| Factor | Hard Money | Seller Financing |
|---|---|---|
| Rate | 10-14% | 4-7% |
| Points | 2-3 | 0 |
| Term | 6-12 months | 3-7 year balloon |
| Due date pressure | Very high | Manageable |
| Origination cost | $3K-$6K | Low |
| Flexibility on extension | Usually no | Often yes |
The carrying cost difference on a $130,000 acquisition over 12 months:
- Hard money at 12%: $15,600
- Seller financing at 6%: $7,800
- **Savings: $7,800**
That $7,800 is additional rehab budget or profit.
The Balloon Is Your Discipline
One concern some operators have with seller-financed BRRRR is the balloon date. What if the rehab runs long, or the refi market tightens?
This is a real risk. Manage it by:
- **Negotiating a longer balloon than you need.** If you think 12 months is enough, get a 3-year balloon. Buffer matters.
- **Communicating with the seller.** If you need 6 more months, most sellers will extend a performing note. Ask early, not at the deadline.
- **Having a backup lender identified.** Know your local community bank before you close the acquisition. Do not discover your DSCR lender won't fund you the week before the balloon.
Woosung lets you track balloon dates across your portfolio alongside each property's current NOI, so you always know which deals are approaching refi window before you're in crisis mode.
Scaling SF-BRRRR
The math is why this works at scale. If each SF-BRRRR deal requires $4,000-$10,000 of final net capital, and you pull $40,000-$60,000 back out per refi, you can theoretically fund 4-6 acquisitions per refi cycle.
Five deals at year 1. Refi three of them. Capital recovered funds three more. By year 3, you have 8 properties, most with bank debt, several with residual seller notes approaching refi.
This is not theory. It is arithmetic.
