How to Use Primary Home Equity to Fund a BRRRR

The Quick Read: Primary home equity funds a BRRRR when you open a home equity line on your residence, use it as bridge money for the purchase and rehab, then repay it with a DSCR cash-out refinance on the rental, so the refinance, not the line, is the real exit and your home backs the plan until it lands. The line is borrowed capital, and the rental has to be able to repay it.

• A home equity line is underwritten on you and your home, not on the rental.
• On a primary residence, the network’s ceiling is 90% CLTV, and only at a 720-or-better credit profile with a line up to $500,000.
• A standard-rental DSCR cash-out tops out around 75% LTV, with about six months of seasoning as the common expectation.
• The appraisal on the rental, not your projected after-repair value, sets how much comes back out.
• An undrawn line is a permission, not committed money, so draw before you need it. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. Investors use it to recycle the same capital into one rental after another instead of saving a fresh down payment each time, according to Inman’s BRRRR explainer. The same source cautions that every step has to land, or the cycle stalls with your money locked in the building. That caution frames everything below.

Key Terms Defined

BRRRR: Buy, Rehab, Rent, Refinance, Repeat, a method for recycling one pool of capital through multiple rentals.

CLTV (combined loan-to-value): All loans secured by the home, added together, divided by the home’s value.

ARV (after-repair value): The value of the property once the rehab is finished, as estimated before the work is done.

Seasoning: The time a lender wants you to have owned the property, or held the loan, before it will refinance.

DSCR: Monthly rent divided by the full housing payment (principal, interest, taxes, insurance, and any HOA dues).

Why Do Investors Use the Primary Home Instead of the Rental?

A just-bought rental has little equity, and an automated valuation will not capture a rehab that is not finished. The primary home usually has the equity already. A line on the residence also leaves a low-rate first mortgage untouched, while a cash-out refinance on the residence would reprice the whole balance.

There is a structural reason as well. Across our wholesale network, home equity lines on investment properties run at a 70% CLTV ceiling, and a property titled in an LLC cannot carry this kind of line at all. Title has to sit with the individual borrower or a revocable living trust. So a BRRRR property that already sits in an LLC needs a vesting change, or a DSCR cash-out, rather than a home equity line.

How Does the Loop Work, Step by Step?

The loop is a five-step sequence, and the equity line only touches the first three steps.

1. Open the line before you need it. Qualification runs on your credit, your debt-to-income ratio, and your home’s combined leverage.

2. Buy. The line funds the down payment, or the whole purchase if you are making a cash offer. A common guardrail is to pay no more than 70% of after-repair value minus repairs, per Inman.

3. Rehab. Draw what the contractors need. The line floats, so carrying cost moves with the market.

4. Rent. The takeout lender will want a lease, proof of deposit and first rent, and a rent appraisal.

5. Refinance and repay. A DSCR cash-out sizes on the new lender’s appraised value, and the proceeds repay the line and any rehab shortfall. Repeat only if the line is still open and the home’s equity remains.

How Much Can You Actually Pull From a Primary Home?

Line size is roughly the lender’s CLTV ceiling times the home’s value, minus the first mortgage, capped by the program’s maximum line. The ceiling depends on credit, and the strongest tier is narrow. Typical network ranges on a primary residence, subject to lender guidelines:

The 720 tier carries a real tradeoff. You can take the 90% ceiling on a line up to $500,000, or a larger line up to $750,000 at a reduced 75% CLTV. A line above $500,000 is primary-residence only, requires a 700 credit profile or better (720 on the longer-draw structure), and needs a full appraisal. Lines at or below $500,000 ordinarily run on an automated valuation instead. The program floor is 600, and a borrower with more than 15 financed properties should confirm eligibility early, since more than 15 is ineligible.

Here is the detail most BRRRR investors miss. At least 75% of the line is drawn at closing, and the pricing floats through both the draw and the repayment period without converting to fixed. You will be carrying interest on most of the line from day one, whether or not the contractor has been paid. Qualifying also happens on the interest-only payment at the maximum draw, with a 50% maximum DTI (45% for credit profiles from 600 to 679).

Two draw structures exist on a primary residence: a 3-year interest-only draw with a 17-year repayment, and a 5-year draw with a 25-year repayment. Pick the longer draw if your rehab or lease-up runs long. Investment-property lines use the 5-year draw and 25-year repayment only.

What Does the Takeout Look Like on the Rental?

A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Across most of the network, cash-out tops out around 75% LTV on a standard long-term rental, and 70% for a short-term-rental cash-out. About six months of seasoning is the common expectation. Credit floors vary: 620 exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers.

On coverage, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 does not mean positive cash flow. DSCR compares rent to the payment only, and repairs, vacancy, management, and capex all sit outside it. Reserves commonly run around six months of PITIA, though they vary with leverage, loan size, and transaction type.

DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The complete DSCR loans guide walks through the full refinance side.

A Worked Example: Base Case and Stress Case

Run the numbers on a modeled rental where purchase plus rehab lands near 70% of projected after-repair value, the guardrail above. All figures here are illustrative index math, not market data.

Base case. The appraisal matches your projection. A cash-out at 75% LTV on that value exceeds your all-in cost, so the line is repaid in full with room for closing costs. The line is free to reuse, if the lender has not frozen it. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Stress case. The appraisal comes in 10% below your projection. A 75% LTV on that lower value now lands slightly under your all-in cost. Before closing costs and carry, you are already leaving some of your own cash trapped. Add a lease-up that runs past the draw period, and a floating balance sits on top of your first mortgage. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

The base case is the sales pitch, and the stress case is the real underwriting. Size the line so the stress case still leaves you whole.

What Are the Biggest Risks to the Primary Home?

Your home is the collateral for the entire plan. If the appraisal runs low, the rehab overruns, or the refinance stalls, you carry a floating balance backed by your residence.

A line can also disappear. The Federal Reserve Board states that lenders can lawfully reduce or limit a line regardless of whether the consumer paid on time. The CFPB’s HELOC brochure names the usual triggers: a fall in the home’s value or a worsening in the borrower’s finances. For an investor, the practical lesson is simple. Draw before closing on the rental, not after.

What If the Refinance Falls Short?

Treat it as a decision, not a failure. You can wait and refinance after more seasoning or a better appraisal, hold the property on the existing line while rent builds, sell and pay the line down, or pay it down from cash flow. A DSCR cash-out also sizes on the lender’s appraised value, not on cost, so a repair-heavy property that the lender views as incomplete may need more time.

Delayed-financing rules are an agency exception for cash purchases and recover documented cost, not after-repair value. A purchase funded by a line on another property is a borrowed-funds case, so do not plan around it.

Where Does the General Rule Break?

• Borrowed funds are traced. DSCR lenders vary on whether line proceeds count as your own cash. Confirm with the lender before you draw.
• Title. An LLC cannot hold a home equity line, so entity-owned rentals need a different exit.
• Property type. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs. The home equity program also excludes co-ops, condotels, and commercial or agricultural zoning.
• Geography. The home equity line is available in Lendmire’s 16 full-service states, narrower than the 41-market DSCR footprint.
• Tax. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.

Is This Right for You?

It fits when you have meaningful equity, a credit profile in the higher tiers, thin liquid cash, and experience estimating rehab costs. It is a poor fit if your reserves are thin, your DTI is near the ceiling, or you cannot afford to carry a floating balance through a slow lease-up. In those cases, a smaller deal, a partner, or a different funding source may be wiser. The calculator on this page gives an illustrative estimate only.
