The BRRRR method

The BRRRR method is a way to build a rental portfolio with the same pool of cash: you buy a property that needs work, rehab it, rent it out, refinance it at its new value, and use the cash the refinance hands back to repeat. When it works, you end up owning a rented property with a long-term loan and most of your money back in your account.

Everything hinges on the refinance. The lender sizes the new loan on what the property appraises for after the work and on the rent it earns, so the plan you make on the day you buy has to survive an appraiser and an underwriter several months later.

How does the BRRRR method work?

Each letter is one stage, and each stage has its own money and its own clock. The cycle below assumes you buy with a short-term loan and refinance into a long-term one, which is how most investors run it.

The order matters. Renting before you refinance gives the lender a lease to count, and waiting out the lender's seasoning period lets the appraised value count instead of your purchase price.

Step 1: Buy below what it will be worth

The deal is made at the purchase. You are looking for a property that is cheap because of its condition, not because of its location: dated kitchens, deferred repairs, a tired landlord, an estate sale. The number that matters is the after-repair value (ARV), what the property should appraise for once the work is done, supported by recent sales of renovated homes nearby.

The 70% rule

Many BRRRR investors screen deals with the 70% rule: pay no more than 70% of the ARV, minus the rehab budget. It is a rough filter, not an underwriting standard, but it has a logic. If your all-in cost lands near 70% of the finished value, a 75% cash-out refinance can pay back nearly everything you spent, including closing and holding costs.

For a house with a $300,000 ARV and a $50,000 rehab, the rule gives a maximum offer of $160,000: 70% of $300,000 is $210,000, minus $50,000.

Rules of thumb break in expensive markets, where 70% deals are rare, and in cheap ones, where a small rehab overrun eats the margin. Run the full numbers with a complete rental property analysis before you offer.

Paying for the purchase and the rehab

Cash is simplest and wins negotiations, but it ties up the most money. Most investors use a hard money or bridge loan: short term, interest-only, at rates well above a long-term mortgage, plus points. These lenders size the loan on cost and cap it against the ARV: commonly up to about 85% to 90% of the purchase price and all or most of the rehab, paid in draws as the work is done, with the total held to roughly 65% to 75% of the ARV. Every month you hold the bridge loan costs interest, so a slow rehab or a slow refinance is expensive.

Step 2: Rehab for the appraiser and the renter

The rehab has two audiences. The appraiser will compare your property with renovated sales nearby, and the renter, or the guest, decides what rent it commands. Spend where both notice: kitchens, baths, flooring, paint, roofs and systems that would otherwise fail an inspection. Skip upgrades the neighborhood will not pay for.

• Budget a contingency. Add 10% to 20% on top of the contractor's numbers; opened walls find surprises.
• Pull permits. Unpermitted work can surface in the appraisal or the title search and delay the refinance.
• Keep every receipt. Some lenders value a recently bought property at its cost plus documented improvements, and the receipts are that documentation.
• Photograph before and after. A list of improvements with photos is the most useful thing you can hand the appraiser.

Step 3: Rent it before you refinance

A DSCR lender sizes the refinance on the rent, so the property should be rented, or close to it, when you apply. For a long-term rental the lender usually counts the lower of the signed lease and the appraiser's market rent. A lease well above what comparable homes rent for rarely helps; a lease at market with a few months of payments collected is the strongest file you can bring.

For a short-term rental the rules are tighter. Some programs want a booking history before they count short-term income on a refinance; others accept a projection from comparable listings at a discount, or fall back to long-term market rent. If you plan to BRRRR a vacation rental, ask how the refinance lender counts income before you buy, and read how DSCR loans treat short-term rentals.

Step 4: The cash-out refinance

The refinance replaces the bridge loan with a 30-year loan sized on the new value. The lender orders an appraisal, verifies the lease and your reserves, and lends a percentage of the appraised value. On a cash-out refinance that is commonly 70% to 75% (80% only at the top credit tiers), and the new loan pays off the bridge loan and the closing costs; anything left over is yours.

Two numbers decide whether the refinance works: the loan-to-value the lender allows, and the coverage. The new payment, including taxes, insurance and any HOA dues, has to be covered by the rent. Most programs want a ratio of at least 1.00 and price best from about 1.25. If you are new to the ratio, how to calculate DSCR walks through it, and the DSCR cash-out refinance guide covers the loan itself.

Seasoning: when the new value counts

Seasoning is how long you must have owned the property before a lender will lend on its appraised value rather than on what you paid. It is the rule that trips up more BRRRR deals than any other.

• Many DSCR programs want about 3 to 6 months of ownership before they use the new appraised value. A few use it sooner, especially when they are refinancing their own bridge loan.
• Before seasoning, many lenders cap the value at your purchase price plus documented improvements, which can leave the new loan too small to pay off the bridge.
• Conventional (agency) cash-out refinances need at least six months on title, and if a mortgage is being paid off it must be at least 12 months old. A bridge loan used to buy usually has to be paid off long before that.
• The agencies' delayed financing exception lets an all-cash buyer refinance within six months, but the new loan is capped at the documented amount you put into the purchase, not the new value.

Ask the refinance lender for its seasoning rule in writing before you buy, and set your rehab and lease schedule around it.

DSCR or a conventional cash-out?

For one or two deals with strong personal income, a conventional loan can be cheaper. For a repeating BRRRR, the DSCR loan's speed, entity vesting and lack of a property cap usually win. Watch the prepayment penalty: if you might sell or refinance again within a few years, how DSCR prepayment penalties work is worth reading before you choose the term.

Step 5: Repeat

The cash that comes back is the down payment for the next deal. How fast you can repeat depends on three things: how much cash each refinance returns, how quickly you find the next property, and the reserves lenders want you to keep.

Reserves are easy to forget. DSCR lenders commonly want 2 to 12 months of the full payment in the bank, often six, and the requirement can grow with each loan. On the example above, six months is $11,459.40 that cannot go into the next purchase. Some lenders let cash-out proceeds count toward reserves, which helps. Keep a cushion beyond what lenders require, too: every property you add is another roof, another vacancy and another insurance renewal.

What can go wrong with BRRRR?

Most BRRRR deals that fail do so at the refinance, months after the decisions that caused it.

• A low appraisal. The comps you counted on are not the ones the appraiser chose, and more cash stays in the deal. Read how rental appraisals work and bring the appraiser your improvements and your best comparable sales.
• A low rent figure. The appraiser's market rent comes in under your lease, coverage drops, and the loan shrinks or reprices.
• Rehab overruns. Every extra month adds bridge interest, and extra spending raises the cost the refinance has to cover.
• Rates moving up. A higher rate on the new loan lowers both the coverage and the cash flow. Run your numbers at a rate a point above today's to see if the deal survives.
• Seasoning and maturity colliding. A bridge loan that matures before you can refinance costs extension fees, often half a point to a point each time.
• Insurance surprises. Premiums in storm-exposed markets can be several times a rule-of-thumb figure, and they count in the payment the rent has to cover.
• Over-leverage. Pulling out every dollar leaves a thin margin. A property that cash flows only at full occupancy is a liability in a slow year.

When does BRRRR make sense?

BRRRR rewards investors who can find discounted properties, manage a renovation and wait out the seasoning without running short of cash. It suits markets where renovated homes sell well above dated ones and where rents support the new payment. It is harder in markets where every listing sells near full value, where renovation costs have outrun what finished homes sell for, or where insurance and taxes eat the rent.

Before you commit to a property, check three numbers: the ARV from renovated sales (a quick estimate from the value calculator is a starting point, not an appraisal), the market rent from comparable leases, and the refinance payment at a realistic rate. If the loan at 70% to 75% of that ARV does not cover your all-in cost, or the rent does not cover the new payment by about 1.2 times, the deal is a renovation project, not a BRRRR.
