How to Calculate BRRRR Strategy Returns in Real Estate

What BRRRR Actually Means Mathematically

BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. The strategy works because a cash-out refinance returns a portion of your initial capital. You redeploy that capital into the next deal. Done correctly, your effective cost basis approaches zero. Done incorrectly, you own a leveraged property with negative monthly cash flow and no exit.

The math has five distinct phases. Each phase has its own return metric. Conflating them is the source of most BRRRR miscalculations.

• Buy: Purchase price plus closing costs equals total acquisition basis.
• Rehab: All-in renovation cost, including carrying costs during the rehab period.
• Rent: Gross annual rent minus operating expenses equals net operating income (NOI).
• Refinance: New loan proceeds minus total capital deployed equals cash returned to investor.
• Repeat: Recycled capital deployed into the next deal multiplies total portfolio yield.

The single metric that ties all five phases together is total annualized return on total capital deployed (ROTCD).

The Four Numbers You Must Calculate Before Closing

1. Total Capital Deployed (TCD)

TCD is not just your down payment. It is every dollar you put in before the refinance closes.

TCD = Purchase Price + Closing Costs (Buy) + Total Rehab Cost + Carrying Costs

Carrying costs include loan interest during rehab, property taxes, insurance, and utilities. On a 4-month rehab with a $200,000 hard money loan at 11% interest, carrying costs alone add $7,333 to your TCD.

2. After-Repair Value (ARV)

ARV drives everything downstream. A 5% ARV miscalculation on a $300,000 property means your projected refinance proceeds are off by $15,000. Most lenders will refinance at 70% to 75% of ARV. Use 70% for conservative modeling.

3. Cash Returned at Refinance (CRR)

CRR = Refinance Loan Amount, minus, Payoff of Acquisition Loan, minus, Refinance Closing Costs

This is your capital recycled. If CRR equals your TCD, you have a "full recycle." If CRR exceeds TCD, you have pulled out profit in addition to recycling capital. If CRR is less than TCD, you have residual equity trapped in the deal.

4. Monthly Cash Flow After Refinance

Monthly Cash Flow = Gross Rent, minus, PITIA (principal, interest, taxes, insurance, association dues), minus, CapEx Reserve, minus, Vacancy Reserve, minus, Property Management

A common industry standard uses 5% for vacancy, 5% for CapEx, and 8% to 10% for property management. Do not skip these line items. Skipping them converts a $340/month cash flow into a $47/month cash flow on paper deals that become negative in reality.

Worked Example 1: The Clean BRRRR

Property: 3-bed/1-bath single-family in a B-class Midwestern market.

| Line Item | Amount | |---|---| | Purchase Price | $115,000 | | Closing Costs (Buy) | $2,400 | | Rehab Cost | $38,000 | | Carrying Costs (5 months, 12% hard money) | $8,050 | | Total Capital Deployed (TCD) | $163,450 |

ARV from licensed appraisal: $230,000

Refinance at 75% LTV: $172,500

Refinance closing costs: $3,800

Payoff of hard money loan: $153,000 (original $115,000 draw plus accrued fees)

CRR = $172,500, minus, $153,000, minus, $3,800 = $15,700

The investor recycled $15,700. TCD was $163,450. Residual equity in the deal: $163,450 minus $15,700 = $147,750.

Monthly cash flow after refinance:

| Line Item | Monthly | |---|---| | Gross Rent | $1,550 | | PITIA (30yr at 7.25%) | $1,178 | | CapEx Reserve (5%) | $77 | | Vacancy Reserve (5%) | $77 | | Property Management (9%) | $139 | | Net Cash Flow | $79/month |

Annual cash flow: $948

Cash-on-cash return on residual equity: $948 / $147,750 = 0.64%

That is not an attractive return on $147,750. The deal only becomes compelling when you add appreciation and mortgage paydown. At 3% annual appreciation on a $230,000 asset, year-one equity gain is $6,900. Loan paydown in year one at a $172,500 balance is approximately $2,640. Total year-one return: $948 + $6,900 + $2,640 = $10,488. Return on residual equity: 7.1%.

That is an honest number. Most investors present this deal as a home run. It is acceptable, not exceptional.

Worked Example 2: The High-Performance BRRRR

Property: 4-unit multifamily in a secondary Sun Belt market.

| Line Item | Amount | |---|---| | Purchase Price | $285,000 | | Closing Costs (Buy) | $5,100 | | Rehab Cost | $62,000 | | Carrying Costs (6 months, 11.5% hard money) | $16,388 | | Total Capital Deployed (TCD) | $368,488 |

ARV from two independent appraisals: $520,000

Refinance at 70% LTV (DSCR loan): $364,000

Refinance closing costs: $7,200

Payoff of hard money: $347,000

CRR = $364,000, minus, $347,000, minus, $7,200 = $9,800

Residual equity trapped: $368,488 minus $9,800 = $358,688.

Monthly cash flow:

| Line Item | Monthly | |---|---| | Gross Rent (4 units at $1,050) | $4,200 | | PITIA (25yr am, 7.6%) | $2,716 | | CapEx Reserve (5%) | $210 | | Vacancy Reserve (7%) | $294 | | Property Management (8%) | $336 | | Net Cash Flow | $644/month |

Annual cash flow: $7,728

Cash-on-cash on residual equity: $7,728 / $358,688 = 2.15%

Add 3.5% appreciation on $520,000 ($18,200) and $5,100 in annual loan paydown. Total year-one return: $31,028. Return on residual equity: 8.65%.

The multifamily deal performs better. But neither deal is the "infinite return" BRRRR proponents advertise unless you achieve a full capital recycle, meaning CRR equals or exceeds TCD.

Why "Infinite Returns" Is a Misleading Metric

Infinite return claims rest on one assumption: zero dollars left in the deal. If you recycle 100% of TCD, the denominator in your return calculation is zero. Dividing by zero produces infinity. This is mathematically true and practically irrelevant.

The relevant question is: what did you do with the recycled capital? If $163,450 came back to you and sat in a savings account earning 4.8%, your opportunity cost is $7,846 annually. The BRRRR deal needs to beat that on a risk-adjusted basis to justify the work, the risk, and the illiquidity.

Track the Total Portfolio ROTCD across all deployed capital, including capital waiting to be recycled. That is the number that reflects actual wealth creation.

The Refinance Is the Hinge Point

Every variable feeds into the refinance. ARV, LTV, interest rate, and closing costs all determine how much capital comes back to you. A 0.5% rate increase on a $364,000 DSCR loan adds $182/month to your PITIA. Over 12 months, that is $2,184 in lost cash flow. Over 30 years, that is $65,520.

Before you pull the trigger on a refinance, model multiple rate scenarios. The CalcMoney Mortgage Calculator lets you test different loan amounts, rates, and amortization schedules against your actual rent roll. Input your numbers, not industry averages.

How to Model Your Own BRRRR Returns

Follow this sequence on every deal:

1. Calculate TCD before you make an offer. Include all acquisition, rehab, and carrying costs.
2. Get two ARV estimates. Use the lower one for your refinance model.
3. Apply 70% LTV to your conservative ARV. That is your maximum refinance loan.
4. Subtract payoff and closing costs from refinance proceeds. That is your CRR.
5. Calculate monthly cash flow using full expense load: PITIA, CapEx, vacancy, management.
6. Compute annual total return: cash flow plus appreciation plus loan paydown.
7. Divide total return by residual equity. That is your true ROTCD.

If step 3 produces a refinance loan that does not cover your TCD, you are not running a full-recycle BRRRR. You are running a leveraged rental acquisition with a partial capital return. That can still be a good investment. Call it what it is.
