How to Fund a BRRRR Down Payment With a HELOC and Still Qualify

The Quick Read: A home equity line of credit can supply the cash for a BRRRR down payment, but it only works when two separate approvals line up: the HELOC itself, and the loan that buys the property. The line has to be open and funded before the contract goes in, and the purchase lender decides whether borrowed money counts toward the down payment, so confirm that before you draw.

• The HELOC is underwritten on your credit, income and equity. The DSCR loan is underwritten on the rental’s coverage.
• The line is qualified on the interest-only payment at the maximum draw, not the amount you plan to use.
• On an investment property, the network’s HELOC ceiling is 70% CLTV with a $500,000 maximum line and a 700 minimum score, subject to lender guidelines.
• The HELOC is bridge money. The cash-out refinance is the real exit.
• Clearing 1.00 coverage is not positive cash flow.

Key Terms Defined

BRRRR: Buy, rehab, rent, refinance, repeat. You recycle the same cash through each deal.

HELOC: A revolving line secured by a property, with a draw period followed by a repayment period.

CLTV: Combined loan-to-value. Every lien on the property added together, divided by its value.

DSCR: Monthly rent divided by the monthly principal, interest, taxes, insurance and any HOA dues.

Seasoning: The time you must own a property, or hold funds, before a lender counts them.

Source of funds: The paper trail showing where your down payment came from.

Two Approvals, Not One

A HELOC supplies cash. It does not buy anything. The purchase is closed by a second loan, usually a DSCR loan, and that lender sets its own rules on borrowed down-payment money.

Those two loans are judged on different things. The HELOC looks at you: credit, income, debt load and equity. The DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Investors get tripped up by assuming that because the DSCR loan skips personal income review, the HELOC does too. It doesn’t. That is why Lendmire’s piece How to Use a Rental HELOC for the Next Down Payment and Still Qualify treats them as separate files.

The federal consumer-finance regulator HELOC brochure lays out the basic structure. A HELOC has a draw period when you can borrow, then a repayment period. With a variable rate, monthly payments can change even if you borrow nothing more. It is an older document, but the mechanics hold.

How Underwriting Treats the Line, Step by Step

Here is the sequence a clean file follows.

1. Pick the collateral. Either your primary residence or an existing rental. A line on your own home is generally easier to qualify for, but the house backs the debt. A line on a rental adds a second lien that has to be paid off or subordinated at the later refinance.

2. Run the equity math. Line size is value at the allowed CLTV, less what you already owe. On an investment property the network ceiling is 70% CLTV. On a primary residence, ceilings reach higher tiers by credit score. The 90% CLTV tier exists only at a 720-or-better credit profile, and only on primary residences and second homes.

3. Qualify the HELOC. Lines are qualified on the interest-only payment calculated on the maximum draw. Borrowing less than the full line does not lower that test. DTI tops out at 50%, with 45% for credit profiles from 600 to 679.

4. Open and fund the line before contract. A line that is still in underwriting when you write an offer is a risk the seller sees too.

5. Draw and deposit. At least 75% of the line is drawn at closing on the network’s programs, so interest starts on that balance right away. Keep every deposit and transfer documented.

6. Close the purchase loan. This can be a hard money loan or a DSCR purchase loan. The purchase lender traces large deposits back to the line.

7. Rehab, then place a tenant. The exit lender needs a lease.

8. Cash-out refinance and repay. The new loan pays off the line. Then you repeat.

Market surveys, such as Yahoo Finance’s overview of HELOCs for down payments, report that HELOC lenders generally want 15% to 20% equity left in the property and a score around 680. That is a market-wide statistic. On Lendmire’s network, an investment-property line needs a 700 minimum score and tops out at 70% CLTV, subject to lender guidelines.

Will the Purchase Lender Accept Borrowed Money?

It depends on the program. Across a wholesale network of DSCR lenders, guidelines on source of funds are not uniform. Some programs accept borrowed down-payment money if it is fully documented. Others are stricter on what counts toward down payment and what counts toward reserves.

Treat down payment and reserves as separate pots. Borrowed money may cover the first and often cannot cover the second. Reserves commonly run around 6 months of PITIA, though that varies by lender, leverage and loan size.

For most purchases, leverage lands at 75% to 80% LTV, meaning 20% to 25% down. Select programs reach 85% LTV, or 15% down, with roughly a 700+ score. A larger down payment lowers the monthly payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

The practical habit: ask the broker whether the target program accepts HELOC-sourced funds before you draw. Do it before the line is funded, not after.

How the HELOC Payment Affects Qualifying

The HELOC payment does not enter the DSCR ratio on the new property. That ratio compares rent to that property’s own PITIA. But the payment still comes out of your pocket during the hold.

The next lender will usually count the line when it reviews your credit and reserves. Debt added to your total obligations can make later approvals harder. And clearing 1.00 coverage is not the same as positive cash flow. Repairs, vacancy, management, utilities and capex all sit outside the calculation. A HELOC payment during a rehab widens that gap.

On coverage itself: 1.00 is where many select programs start. A separate path through select lenders in the network goes below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.

The Exit: What Pays Off the Line

The refinance carries three claims on the proceeds: the original purchase loan, the HELOC balance, and the rehab spend. The new loan has to cover all three.

Cash-out refinances on the network top out around 75% LTV for standard rentals, with about 6 months of seasoning as the common expectation. If the post-rehab appraisal comes back light, the refinance may not return everything. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

That is the failure case. A buy at market price with little rehab leaves cash stuck in the deal, because there is no forced appreciation. The missing “R” in BRRRR is real. Plan B should be written down before the draw: a longer hold, a smaller rehab scope, or a paydown from savings.

Where the General Rule Breaks

LLC title. The HELOC cannot be held by an LLC. Title must sit with an individual or a revocable living trust. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out instead of a HELOC. LLC-titled DSCR loans are available subject to lender program eligibility.

State footprint. HELOC availability is limited to 16 full-service states. The DSCR footprint is wider, covering 40 states plus Washington, D.C.

Freeze or reduction. A lender can freeze or cut a line before your next closing. Rental-secured lines are scarce, so don’t count on one for the repeat step.

Payment shock. The interest-only draw gives way to amortization. Pricing floats through both phases and never converts to fixed.

Property type. Manufactured homes, log homes and barndominiums are not offered under the network’s DSCR programs.

Stacked leverage. Using HELOC money for an all-cash buy, then refinancing to fund the next down payment, builds debt fast.

Collateral risk. A line on your home puts the home at risk if you can’t repay.

What the Decision Looks Like in Practice

Picture an investor with a paid-down primary home, a 720 score, and a distressed duplex under consideration. The line gets opened first. The broker confirms the DSCR purchase program accepts documented HELOC funds. The investor draws, deposits, and keeps statements. After the rehab and a signed lease, a cash-out refinance repays the line.

Now change one input: the duplex is bought near market with a light rehab. The appraisal does not lift. Cash stays in the deal, and the line stays open longer than planned. Same structure, different outcome. Size the line for the version where the refinance underperforms.

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.
