A BRRRR refinance is a new loan that replaces acquisition financing after renovation and rental stabilization.
How much cash comes back after refinancing?
Cash returned is the new loan less actual payoffs, closing costs, and points. A negative result means cash is required to close, not that cash was recovered.
The Three Numbers That Determine Whether a BRRRR Deal Works
Most investors who use the BRRRR method — Buy, Rehab, Rent, Refinance, Repeat — focus on the wrong number at the wrong time. They negotiate the purchase price hard, estimate rehab costs carefully, and then assume the refinance will work out. It often does not.
The BRRRR cycle has three variables that determine whether you actually recycle capital or just own another rental with debt:
- Your ARV (After-Repair Value) — what the property will appraise for after rehab
- Your maximum DSCR-constrained refi loan — the largest loan the rental income will actually support
- Your cash-left-in-deal — how much capital you cannot get back out
Get all three right before you buy. Get any one wrong and you either leave money on the table or get stuck.
Why ARV Is the Highest-Risk Assumption
ARV is not a fact — it is an opinion. Your opinion, your agent's opinion, and eventually an appraiser's opinion. The appraiser's opinion is the only one that matters for your refinance.
Most BRRRR investors underwrite to a single ARV number. That is the wrong approach. The correct approach is to underwrite to an ARV *range* and then answer: what happens to my deal if ARV comes in 10% below my estimate?
On a property where you estimated ARV at $300,000:
- A 10% shortfall puts ARV at $270,000
- At 75% LTV, your max refi loan drops from $225,000 to $202,500 — a $22,500 reduction in capital recycled
- If your all-in cost was $230,000, you went from "cash-out" to "cash-left-in-deal of $27,500"
The BRRRR Calculator runs this scenario automatically. Enter your ARV and it shows you the downside at -5%, -10%, and -15% before you commit.
ARV Confidence Factors
Not all ARV estimates carry the same risk. Your confidence in the ARV should be higher when:
- There are 3+ sold comps within 0.5 miles in the past 90 days
- Comps are similar in size (within 15% of square footage) and condition
- The rehab scope is cosmetic — paint, flooring, fixtures — not structural
- The market has low days-on-market and flat-to-rising median prices
Your confidence should be lower when:
- Comps are sparse, old, or require large adjustments
- The rehab involves structural work, addition, or full gut
- The market has high days-on-market or falling prices
- The price-per-square-foot variance among comps is high
This is exactly what the BRRRR Investors tools were built to help with.
DSCR-Constrained Refi: The Number Most Investors Get Wrong
The standard BRRRR underwriting mistake is sizing the refinance loan at 75% of ARV and calling it done. That gives you the *LTV-constrained* maximum loan. But there is a second constraint most investors ignore until they sit across from an underwriter: DSCR.
DSCR — Debt Service Coverage Ratio — is calculated as:
Annual Net Operating Income / Annual Debt Service
Most lenders require a minimum DSCR of 1.20 to 1.25 on DSCR loans. That means your NOI must be at least 20–25% higher than your annual mortgage payment.
Here is the problem: the DSCR constraint uses the lender-qualifying rate — typically the note rate plus 100 basis points — not the actual note rate. So if your actual rate is 7.5%, the lender qualifies you at 8.5%.
Example:
- Property: 3BR/2BA, $1,800/month rent
- NOI after vacancy (7%) and opex (35%): approximately $1,050/month = $12,600/year
- Lender qualifying rate: 8.5% on a 30-year term
- Maximum annual debt service at 1.20 DSCR: $12,600 / 1.20 = $10,500/year = $875/month
- Maximum loan at $875/month at 8.5%: approximately $114,000
If your 75% LTV loan would have been $180,000 but DSCR limits you to $114,000, you have $66,000 more capital left in the deal than you planned.
The DSCR Loan Modeling tools calculate both constraints and show you the binding one — LTV or DSCR — so you know before you buy.
Cash-Left-In-Deal: The Number That Determines Whether the Deal Worked
After ARV and the refi loan, the math is simple:
Cash Left in Deal = All-In Cost - Refi Proceeds
All-In Cost includes:
- Purchase price including down payment and fees
- Total rehab cost (budget 10–15% contingency)
- Carry costs: interest, insurance, taxes during hold
- Closing costs on purchase and refinance
Refi Proceeds is the lesser of the LTV-constrained loan and the DSCR-constrained loan, minus closing costs.
The BRRRR math goal is zero or negative cash-left-in-deal — meaning you pulled out everything you put in. In practice, most deals leave some capital in. The question is how much and whether the ongoing return justifies it.
What a Good BRRRR Outcome Looks Like
- Cash recycling %: > 80%
- Cash-left-in-deal: < 20% of all-in cost
- Post-refi DSCR: >= 1.25
- Post-refi CoC return: >= 8% on cash remaining
Putting It Together: A Pre-Buy BRRRR Underwriting Checklist
Before you make an offer on a BRRRR deal:
- ARV from 3+ comps, with downside scenario at -10% modeled
- Rehab budget with 10–15% contingency
- Post-stabilization rent estimate from market data
- NOI calculated: rent x (1 - vacancy) x (1 - expense ratio)
- DSCR-constrained max refi loan calculated at lender qualifying rate
- LTV-constrained max refi loan calculated at 75% of ARV
- Binding constraint identified (DSCR or LTV — whichever is lower)
- Cash-left-in-deal calculated under base case and downside ARV
