How to Fund a BRRRR With a HELOC and Repay It at Refi

The Quick Read: A home equity line of credit (HELOC) works as bridge money in a BRRRR (buy, rehab, rent, refinance, repeat). You borrow against equity you already own, spend it on the new property, then a cash-out refinance pays the line back. The plan only works if the refinance appraisal and the rent clear the whole debt stack.

• The HELOC is acquisition and rehab capital. The refinance is the exit, and the line is not.
• On this network, an investment-property line caps at 70% CLTV and $500,000, with a 700 minimum credit score.
• A DSCR cash-out exit tops out around 75% LTV on standard rentals, and the appraised value decides the outcome.
• Most of the line is drawn at closing, so interest starts building before the first contractor shows up.
• LLC-titled properties cannot hold these lines, which pushes entity-held rentals toward a DSCR cash-out instead. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Most BRRRR plans fail at the appraisal, not at the purchase. This article walks the mechanics from opening the line to paying it off, then covers the places the general rule breaks. Program figures below come from the select wholesale lenders Lendmire works with, and every file is reviewed individually.

Key Terms Defined

You will see these terms throughout. Each one gets defined once here.

• HELOC: A revolving credit line secured by property you own, where you borrow, repay, and borrow again up to a limit during a set draw period.
• Draw period: The stretch when you can borrow from the line, usually interest-only on the network programs described here.
• CLTV (combined loan-to-value): All loans secured by the property, including the line, divided by the property’s value.
• ARV (after-repair value): The value of the property once the rehab is finished, as an appraiser sees it.
• DSCR (debt service coverage ratio): The property’s monthly rent divided by its monthly payment of principal, interest, taxes, insurance, and any HOA dues.
• PITIA: Principal, interest, taxes, insurance, and association dues, which is the payment the DSCR test measures.
• Seasoning: The waiting period a lender wants between buying a property and refinancing it. Across most of the network, about 6 months is the common expectation on a cash-out.

Which Property Should Secure the Line?

The collateral choice decides where your risk sits. You can put the line on your primary home, on a second home, or on a seasoned rental you own in your own name. You do not put it on the property you are about to buy. Here is how the options compare.

The ceilings in that table are the network’s. On a primary residence, 90% CLTV applies only at a 720 or better credit profile, on lines up to $500,000. On an investment property, the ceiling is 70% CLTV with no higher tier. The maximum investment line is $500,000.

Lenders commonly size a line as a percentage of appraised value minus what you still owe on the first mortgage. The federal consumer-finance regulator’s HELOC booklet describes that general method. Network guidelines set the actual percentages by occupancy and credit tier.

Few lenders write lines on rentals at all. That is why most investors who use this strategy borrow against a primary home.

How the Line Funds Each Stage

A HELOC touches every step of the cycle. The table shows the line’s role and the main risk at each stage.

On a purchase with a standard DSCR loan, most files land at 75% to 80% LTV on an investment property. That means a 20% to 25% down payment. Many investors use the HELOC for that down payment, then use the same line for rehab. Others buy with cash from the line and skip the purchase loan. A cash purchase gives the later refinance a clean lien position.

Rehab is where the draw schedule matters. Because most of the line is typically drawn at closing, you hold cash and pay interest on it while the work proceeds. Interest on an investment line runs under a 5-year interest-only draw and a 25-year repayment term. The line’s pricing floats and never converts to a fixed rate.

Rent and seasoning come next. The unit needs a signed lease, and the refinance lender will want to see the building actually performing. Seasoning stretches the carry period, and carry is where plans leak money.

A Worked Example With a Failure Case

These figures are modeled assumptions, not market data. They use percentages of ARV so you can plug in your own deal.

Base case. Say you plan a purchase at 60% of the expected ARV and a rehab budget of 10% of ARV. Add carry and closing costs of 3% of ARV. Your all-in cost is 73% of ARV.

A DSCR cash-out on a standard rental tops out around 75% LTV, assuming the appraisal lands on target. That loan returns your full cost and leaves a thin cushion. The HELOC balance and any first lien are paid off at closing, and the rental covers its payment at roughly the coverage the lender requires. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Low-appraisal case. Now suppose the appraisal comes in at 90% of what you expected. Your 73% all-in cost becomes about 81% of the appraised value. A 75% cash-out loan cannot cover that, so you are short by roughly 6% of the appraised value, before exit costs. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

You have four moves from there:

1. Dispute the appraisal. Provide stronger comparable sales and ask the lender for a review.

2. Bring cash to closing. This works only if you kept a reserve for it.

3. Wait and re-season. This buys time but extends the carry on a variable line.

4. Sell. If the numbers never recover, a sale ends the carry.

The break-even test is simple. Needed appraised value equals the HELOC balance plus any first lien plus exit costs, divided by the cash-out LTV cap. Run it at a conservative ARV, never at the hoped-for number. A purchase near 50% to 60% of ARV with a modest rehab gives you room to be wrong.

How the Refinance Repays the Line

The refinance is a new loan that must pay off every lien on the property. That includes the first mortgage, any HELOC sitting on it, and ideally your rehab spend. Here is how underwriting treats it, step by step.

Step one: the lender orders an appraisal. It values the property and estimates market rent. The value sets the loan size, and the rent feeds the coverage test.

Step two: the lender applies the cash-out cap. On a standard rental, a DSCR cash-out tops out around 75% LTV. On short-term-rental collateral, the cash-out ceiling is 70%. Multiply the cap by the appraised value and you have the maximum new loan. If that is smaller than your lien stack, you bring cash. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

Step three: the lender tests rental coverage. DSCR compares rent to PITIA, nothing more. The 1.00 level is where many select programs start, and a stronger ratio opens better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 does not mean the property produces positive cash flow, since repairs, vacancy, management, and utilities sit outside the calculation.

Step four: the lender checks seasoning and you. About 6 months of ownership is the common expectation for a cash-out. Credit matters too. A 620 floor exists in parts of the network, most programs want around 660, and 700 or better opens the strongest leverage tiers. Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA.

DSCR loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), with 30-year fixed as the spine. Select lenders also offer 40-year terms, interest-only periods, and ARM structures. Because the DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, your personal income documents matter less than they did for the line. The line itself was underwritten on your credit and equity, with a 50% maximum DTI.

For the full picture of how these loans work, see Lendmire’s complete DSCR loans guide. The exit loan is where the plan either pays off or doesn’t.

When the HELOC sits on a different property, such as your home, the refinance proceeds repay the line balance. That frees the line for the next deal. If the line sits on the subject property, it has to be paid off at closing or subordinated, and subordination needs the line holder’s consent.

Where the General Rule Breaks

Every rule above has exceptions. These are the ones that catch investors.

Entity title. These lines require the borrower to hold title as an individual or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change or a DSCR cash-out instead, subject to program terms. For the appraisal side of an entity-held BRRRR, see Lendmire’s piece How an LLC BRRRR Appraisal Clears the Private Loan at Refi.

The line on the new property. A lien on the property you just bought can defeat cash-purchase treatment and adds a second payoff at refinance. A line on a different property avoids both problems.

Automated valuation. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. That value reflects the property as it stands today, not as it will stand after rehab. A borrower may request a full appraisal, and a higher CLTV can trigger a secondary valuation.

The draw-period cliff. A HELOC has two phases, a draw period and a repayment period. The CFPB’s HELOC overview notes that payments are often significantly higher once repayment begins. It adds that HELOCs usually carry variable rates, and that some borrowers must repay the full balance when repayment starts. A BRRRR timeline should end long before that.

Delayed financing. Agency loans have an exception that waives the title-seasoning wait for a cash purchase. Under that exception, a HELOC on another property can be a documented source of funds, but the baseline expectation is a borrower who has been on title for six months. It still sizes proceeds to documented cost, not after-repair value. That is a conventional-loan rule. DSCR lenders set their own seasoning and exception policies.

Borrowed down-payment funds. A purchase lender will trace large deposits. Some programs accept HELOC-sourced money and some look at it harder. Confirm with the purchase lender before you draw.

Reuse limits. A line is not an endless well. You are limited to three lines, and an investor with more than 15 financed properties is not eligible. Lenders can also freeze or reduce a line, and subsequent draws after closing carry minimum amounts. Do not build a plan that assumes the line will be there for the next deal.

Property types. DSCR financing through the network does not cover manufactured homes, log homes, or barndominiums. The line programs also exclude co-ops, condotels, and commercial or mixed-use properties.

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.

HELOC or Something Else?

Not every investor should use a HELOC. This table matches funding sources to investor profiles.

Availability matters too. The line programs run through Lendmire’s 16 full-service states, which is narrower than its DSCR footprint of 41 markets, including Washington, D.C. Investors outside those states may need a different funding source for the acquisition.

An honest toss-up shows up in the middle of that table. A HELOC preserves a low-cost first mortgage and avoids a cash-out refinance on the home, but the variable payment and the home as collateral are real exposure. Investors with thin equity may do better with a DSCR cash-out on an existing rental, even though that route takes longer to build.

Before You Draw: A Checklist

• Run the break-even test at a conservative ARV, with the refinance cap applied.
• Confirm which property secures the line, and how it is titled.
• Budget the carry, remembering that most of the line is drawn at closing.
• Check the line’s draw period against your rehab and seasoning timeline.
• Keep HELOC draws in a dedicated account, and keep the statements.
• Ask your purchase lender how it treats borrowed funds.
• Line up the exit loan, including its seasoning and coverage requirements, before you spend.
• Hold reserves for a low appraisal, since the shortfall is cash you may have to supply.

Next Steps

If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. The site’s illustrative calculator can help you size a line from your available equity. Your exit loan still needs its own review of appraised value, rental coverage, and seasoning. A line that fits the exit is worth far more than a big line with no plan for repayment.
