The BRRRR method, explained without the hype

The short answer

BRRRR stands for buy, rehab, rent, refinance, repeat. It is a capital-recycling strategy: buy a property that needs work, renovate it, lease it, refinance it, and use the cash that comes back to do another deal.

The important word is if. The refinance does not create cash out of nothing. It replaces a short-term acquisition loan with a longer-term loan based on the property’s after-repair value. If the new loan is large enough to pay off the old loan and the refinance costs, the remainder comes back to the investor.

That remainder is the point of the strategy. It is also where most BRRRR projections go wrong.

A BRRRR is not automatically a no-money-down deal. It is a deal where the cash invested is measured and the refinance is tested against it. A property can be a good rental and still be a poor BRRRR if too much cash stays trapped after the refinance.

The BRRRR calculator keeps the entire cash cycle in one place: purchase, rehab, hard-money carry, refinance, cash left in the deal, post-refi cash flow, and DSCR. If you need to price the short-term loan itself, the hard money loan calculator separates the commitment from the initial advance and adds points, interest, fees, and cash to close.

What the five phases actually require

Buy

The buy phase is not just the purchase price. It is the purchase price plus closing costs, due diligence, and the cash needed to close the acquisition loan. A distressed property often has title, inspection, or code issues that cost money before the rehab starts.

The acquisition loan is usually based on the purchase price plus the rehab budget. The contingency is typically cash. That distinction matters because a 10% contingency on a $35,000 rehab is another $3,500 out of pocket, and it is not automatically financed by the acquisition lender.

Rehab

The rehab phase is where the budget meets reality. A scope of work should separate cosmetic work from structural work, permitting, and systems. A contingency is not optional. The question is whether it is 10%, 15%, or higher given the condition of the property and the contractor.

Rehab time matters as much as rehab cost. Every extra month of holding can add interest, taxes, insurance, utilities, and management or security costs. A project that runs two months long can consume the cash that was supposed to come back at the refinance.

Rent

The rent phase is not only finding a tenant. It is finding a tenant at the rent the refinance underwriting assumes. A pro forma rent that has not been tested against comparable units is an assumption, not evidence.

Vacancy, lease-up time, and concessions belong in the plan. A property that takes three months to lease is carrying the loan for three more months than a six-month schedule assumes.

Refinance

The refinance phase replaces the acquisition loan with a longer-term loan. The new loan is usually sized as a percentage of the appraised after-repair value. The lender will also look at the property’s income, the borrower’s credit and reserves, and its own DSCR and cash-out rules.

The refinance is not guaranteed to return the cash invested. The appraisal can come in below the target ARV. The lender can cap the LTV below the number used in the projection. The rate can move. The property may need to be seasoned or leased for a minimum period before it qualifies.

Repeat

The repeat phase only works if the refinance actually freed capital. If the deal left cash in the property, the investor can still hold it as a rental, but the next purchase requires new capital. That is a different outcome from the one the strategy is usually sold on.

The cash cycle, in order

A BRRRR has two separate cash events that are easy to blur together:

1. Cash goes in at acquisition and during the hold. This includes the down payment or equity gap, closing costs, rehab, contingency, lender fees, hold interest, and carrying costs.
2. Cash comes back at the refinance. The new loan pays off the acquisition loan and the refinance costs. Whatever remains is cash back to the investor.

The number that matters is the difference:

Cash left in the deal = cash invested − cash back at refinance

A positive result means cash is still in the property after the refinance. A negative result means the refinance returned more cash than was invested, before income taxes and other costs outside the model.

The related measure is capital recycled:

Capital recycled = cash back at refinance ÷ cash invested × 100

If an investor put in $50,000 and got $34,250 back, the deal recycled 68.65% of the capital. That is not a failure. It is simply a different outcome from a 100% capital recovery, and it changes how much cash is available for the next deal.

The detailed arithmetic is in the cash left in the deal formula guide.

The numbers that decide the deal

A BRRRR underwrite comes down to four relationships.

1. All-in basis versus ARV

The purchase price alone does not tell you whether the deal works. Start with the project cost: purchase price plus closing costs plus the full rehab with contingency. Compare that number with the ARV, not with the asking price. For a stricter view, add points, hold interest, and carrying costs to see the cash invested. Refinance costs are recovered at the refinance, so they reduce cash back.

A common shorthand is that the project cost should be comfortably below the ARV. How far below depends on the refinance LTV, the costs to close and hold, and the rent the property can support.

2. Refinance LTV

The refinance loan is a percentage of the appraised value. At a 75% LTV, every $10,000 of ARV supports $7,500 of new loan. At a 70% LTV, it supports $7,000. A small change in LTV can move the cash back by thousands of dollars.

The calculator uses the LTV you enter. It does not assume that a lender will approve 75%, and it does not cap the loan at a 75% rule.

3. Rent, NOI, and DSCR

The refinance lender will underwrite the property’s income, not the investor’s hopes. DSCR is:

DSCR = net operating income ÷ annual debt service

If NOI is $19,380 and annual refinance debt service is $15,177, DSCR is about 1.28. That is above a 1.25 target, but not by much. A lower rent or a higher rate can push it under the lender’s minimum.

4. Cash left and post-refi cash flow

A deal can return all of its cash and still produce negative cash flow. That is not automatically a bad outcome if the investor planned for it, but it is a different risk than a deal that returns most of its cash and cash flows.

The calculator shows both:

• Cash left in the deal, which measures capital recycling.
• Post-refi cash flow and DSCR, which measure whether the property can carry the new loan.

A complete underwrite looks at both. A deal that returns 100% of the cash but has a DSCR of 1.05 is borrowing trouble. A deal that leaves 20% of the cash in the property but has a DSCR of 1.40 and positive cash flow may be a better long-term hold.

The 75% rule: useful screen, incomplete underwrite

The 75% rule says the purchase price plus rehab should be no more than 75% of the ARV. The logic is simple: if the refinance is at 75% LTV, a basis at or below 75% of ARV leaves room for the new loan to cover the project.

But the rule is a screen, not a full cash analysis. It usually ignores:

• Purchase closing costs
• Rehab contingency
• Hard-money points
• Hold interest
• Property taxes, insurance, utilities, and other carrying costs
• Refinance closing costs
• The difference between the rehab budget and the rehab loan base

A deal can pass the 75% screen and still leave cash in the property. That is exactly what happens in the calculator’s default example.

The purchase price plus rehab is $185,000 against a $260,000 ARV, or about 71.2%. That is below 75%. Yet the deal leaves about $15,644 in the property after the refinance because closing costs, contingency, points, hold interest, carrying costs, and refinance costs all have to be recovered too.

To return the cash invested at a 75% LTV, the ARV would need to be about $280,858. That is roughly 8% above the $260,000 assumption. The gap is the difference between a screening rule and a cash-flow underwrite.

A worked example

The calculator’s default deal is a $150,000 purchase with $4,000 closing costs and a $35,000 rehab budget with a 10% contingency. The ARV is $260,000.

Acquisition and hold:

• Rehab with contingency: $38,500
• Project cost: $192,500
• Acquisition loan at 85% LTC: $157,250
• Points at 2%: $3,145
• Hold interest at 11% for 6 months: $8,648.75
• Holding costs for 6 months: $2,850
• Cash invested: $49,893.75

Refinance:

• Refinance loan at 75% of ARV: $195,000
• Acquisition payoff: $157,250
• Refinance costs: $3,500
• Cash back: $34,250
• Cash left in the deal: $15,643.75
• Capital recycled: 68.65%

Post-refinance:

• NOI: $19,380
• Annual refinance debt service: $15,177.20
• Annual cash flow: $4,202.80
• Monthly cash flow: $350.23
• DSCR: 1.28
• Cash-on-cash return on cash left: 26.87%
• Cash-on-cash return on original cash: 8.42%

The post-refi cash-on-cash return looks high because the denominator is the cash left in the deal, not the original cash invested. That is a legitimate measure of the return on the remaining equity, but it is not the same as the return on the original check.

The deal is not a failure. It left cash in the property, but it also produced positive cash flow and a DSCR above the target. The question is whether the investor is comfortable with $15,644 of capital tied up in exchange for that cash flow and the remaining equity.

Test the ARV before you trust the refinance

The ARV is the most consequential assumption in a BRRRR. The calculator’s stress table changes only the ARV; rent, expenses, the acquisition loan, and the refinance terms stay constant.

At a 10% lower ARV of $234,000, the refinance loan falls, cash left rises to about $35,144, and DSCR rises to about 1.42 because the smaller loan has lower debt service. The cash outcome gets worse even though coverage improves. That is a useful reminder that a safer lender ratio is not the same as a better cash result.

At a 10% higher ARV of $286,000, the refinance loan rises, cash left becomes about negative $3,856, and DSCR falls to about 1.16 because the larger loan has higher debt service. In that case the deal returns more than the cash invested but no longer meets a 1.25 DSCR target.

The point is not to predict the ARV. It is to see how the deal behaves if the appraisal disagrees with the pro forma.

Why BRRRR deals fail

Most BRRRR failures are not mysterious. They come from assumptions that did not survive contact with the project.

• The ARV was too high. The appraisal uses closed comparables, condition, and market evidence. A renovated property is not automatically worth the top of the range.
• The rehab cost or timeline was too low. Contractor bids, permitting, and change orders can consume the contingency and extend the hold.
• The rent was not proven. A rent estimate from a listing is not the same as a signed lease.
• The refinance did not qualify. DSCR, seasoning, credit, reserves, or the lender’s cash-out limit can change the loan.
• The rate moved. A higher refinance rate lowers cash flow and can push DSCR below the target.
• The investor ran out of liquidity. A BRRRR can require reserves for the hold, the refinance, and the first months after stabilization.
• The property was treated as a no-money-down deal. The strategy can recycle capital, but it does not eliminate the need for capital in the first place.

What the calculator includes, and what it does not

The BRRRR calculator includes the purchase price, purchase closing costs, rehab budget, contingency, acquisition loan, points, other acquisition fees, hold interest, property-level holding costs, refinance loan, refinance costs, post-refi debt service, NOI, DSCR, cash left, and capital recycled. It also includes ARV stress, reverse solves, a phase timeline, saved deals, A/B comparison, CSV export, and a share link.

It does not include construction draws, minimum-interest rules, extension fees, prepayment penalties, a failed refinance, income taxes, depreciation, or sale proceeds. Those are separate risks and separate models.

The methodology page documents the formulas and conventions behind every number.

A practical underwriting sequence

1. Support the ARV with comparable sales. Use closed sales, adjust for condition and location, and keep a conservative case.
2. Build the rehab scope and budget with a contingency. Separate must-do work from nice-to-have work.
3. Schedule the hold honestly. Rehab months plus lease-up months, not the best-case contractor promise.
4. Price the acquisition loan. LTC, rate, points, other fees, and whether the lender funds draws or requires cash upfront.
5. Price the refinance. LTV, rate, term, costs, seasoning, DSCR, and cash-out limits.
6. Run the base case and a downside case. Lower ARV, longer hold, higher rate, and lower rent.
7. Check liquidity. Can you fund the hold and the refinance even if the cash back is lower than planned?
8. Then negotiate the purchase. The price is one lever, not the whole deal.

Bottom line

BRRRR is a useful framework because it forces an investor to connect the acquisition, the rehab, the rent, and the refinance. It is not a magic formula, and it is not a guarantee of no money down.

The deal works when the all-in basis, the ARV, the refinance terms, and the rent all leave enough room to recover the cash invested and carry the new loan. The calculator is a way to see that room before you commit, not after the appraisal comes back.
