Can You Use a HELOC as a Down Payment on Another Home?

The Quick Read: Yes, often, but the purchase lender decides whether borrowed money counts. A HELOC is a possible source of funds, never a guaranteed one. Some programs accept a documented draw. Others want your own unborrowed cash.

• A HELOC (home equity line of credit) is a separate loan that you must open and draw on before you go under contract.
• Two lenders review you: the line lender looks at you, and the DSCR lender looks at the rental.
• Borrowed funds often pass the down payment and closing cost tests but fail the reserves test.
• A plan that is 100% borrowed can fail on that point alone.
• Clearing 1.00 coverage does not mean the rental cash flows, and the HELOC payment sits outside that ratio.

Key Terms Defined

HELOC: a revolving line of credit secured by the equity in a home you own. You borrow against it, repay, and borrow again during the draw period.

CLTV (combined loan-to-value): all loans on a property added together, divided by its value. It tells you how much equity is left after the HELOC.

DSCR (debt service coverage ratio): monthly rent divided by the monthly PITIA. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.

PITIA: principal, interest, taxes, insurance, and any association dues on the rental.

Reserves: liquid cash left over after closing, counted in months of PITIA.

Seasoning: how long money sits in your account, or how long you own a property, before a lender treats it as settled.

How Does a HELOC Down Payment Actually Work?

You borrow against equity you already own, move the cash into your own account, and use it as the down payment on the next property. The sequence matters. The line has to exist and be funded before the contract, not after.

Two separate approvals sit behind that one plan. The HELOC lender underwrites you: credit, debt load, equity, and existing liens. The DSCR lender underwrites the new rental: rent against PITIA, plus credit, leverage, and reserves. Passing one review does not carry you through the other. A DSCR loan does not mean skipping personal qualification, because the HELOC itself is underwritten to you.

Here is the order brokers like to see:

1. Ask the purchase lender first. Before you open or draw anything, confirm whether borrowed funds count toward the down payment, closing costs, and reserves. Get the answer in writing if you can.

2. Open and fund the line. Draw the cash and let it land in your own account.

3. Save the paper trail. Keep the HELOC agreement, the draw confirmation, and the statement showing the deposit. Underwriters question large deposits, and a clean trail answers the question before it is asked.

4. Provide the property documents. The DSCR file still needs a lease or rent schedule, an appraisal, and insurance.

Many lenders that fund conventional owner-occupied loans accept secured borrowed money. That acceptance does not carry over automatically to DSCR or other non-QM programs. Across the wholesale network Lendmire places files with, treatment varies from lender to lender.

What Does the DSCR Lender Check?

The DSCR lender checks three separate buckets: the down payment, closing costs, and reserves. Money can pass one test and fail another. A common pattern is that borrowed funds are accepted for the first two with documentation, then excluded from reserves. An undrawn line generally counts for nothing, because it is permission to borrow and not money in the bank.

On leverage, most purchase files in the network land at 75%-80% LTV, which means 20%-25% down. Select high-leverage programs reach 85% LTV on a purchase, typically with a score around 700 or better. A bigger down payment lowers the monthly obligation and can lift your 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.

Coverage works like this. The lender divides monthly rent by PITIA. Many select programs start at 1.00, where rent just covers the payment, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. A conventional file would add your HELOC minimum payment to your debt-to-income ratio. A DSCR file does not run that test, so the HELOC payment generally sits outside the ratio.

Outside the ratio does not mean outside your life. That payment still comes out of your pocket every month.

Other typical network guidance:

• Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
• Reserves: commonly around 6 months of PITIA. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived. Larger loans typically step up to about 9 months.
• Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders).

All of this is subject to lender guidelines and a full file review. Programs change.

What Can the HELOC Itself Borrow?

The HELOC ceiling depends on the occupancy of the home you pledge, not the home you are buying. The pledged property is the one that secures the line. For the figures below, Lendmire’s network offers HELOCs in a narrower set of states than its DSCR footprint of 41 markets, including Washington, D.C.

The 90% ceiling on second homes and primary residences exists only for borrowers at 720 or better, and only on lines up to $500,000. A primary-residence line above $500,000 caps at 75% CLTV and requires a full appraisal. It also needs a credit score of 700 or better, or 720 on the longer-runway program, which is the wholesale HELOC program built around a 5-year interest-only draw and a 25-year repayment period. Investment property lines top out at 70% CLTV, with no tier above it. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

Here is how the line itself is built. These are standalone lines in first or second lien position. Investment lines run the 5-year draw followed by the 25-year repayment period. Primary-residence and second-home lines offer two draw structures, either 3 years plus 17 or 5 years plus 25. At least 75% of the line is drawn at closing, and the cost of the line floats with the market over its life. The DTI ceiling is 50%, and the lender reviews your file on the interest-only payment calculated on the maximum draw.

Title is the sharp edge. The pledged home must be held by you individually or by a revocable living trust. LLCs, corporations, and partnerships cannot hold title on these lines. If your rental sits in an LLC, you would need a vesting change, or you could look at a DSCR cash-out refinance instead. DSCR loans themselves can go to LLC borrowers, subject to program terms.

Where Do These Plans Break?

Most failures come from the same few spots.

A fully borrowed down payment. Some programs cap the borrowed share, and combined leverage across both liens limits how much real equity you hold in the new deal. A HELOC cannot fund 100% of a DSCR purchase on every program.

Seasoning. Some lenders want the funds to sit in your account for a stretch. Others accept a recent draw if you disclose the source up front. One lender’s habit is not a rule, so ask yours.

A line that freezes. The CFPB explains that a HELOC lender may stop further draws if your home’s value drops significantly. It also warns that failing to repay on schedule can cost you the home. An unused line is not committed money, so draw before you rely on it.

Renting out the secured home. The CFPB’s HELOC booklet notes that renting the home to others may be prohibited under the line’s terms. Read your agreement if you plan to pledge a property you also rent out.

Big retail lenders. Large depository lenders often want unborrowed equity in the deal. Business-purpose investor programs tend to be more flexible, though not unlimited. DSCR loans are designed for non-owner-occupied investment properties, so they are reviewed differently from a standard owner-occupied mortgage.

The line was opened too late. Opening a HELOC in the middle of a purchase complicates the file. Open it before you make offers, and tell the purchase lender what you did.

Is It a Smart Move for an Investor?

It works when two things hold at once. The rental has to carry the first mortgage on its own, and you have to cover the HELOC payment from your own income. It is a poor plan when you need the rental to cover both.

The upside is real. A HELOC keeps your savings liquid, and the rental’s income carries its own loan. For an investor who owns a paid-down home, it can turn idle equity into a purchase.

The risks are just as real:

• Near-100% financing. If the down payment is borrowed, the property is effectively financed close to full value. The rent is measured against the first mortgage only, so the HELOC payment has to come from your own income, not from the property.
• Your own home is on the line. Failing to repay a HELOC as agreed can lead to foreclosure on the home that secures it.
• The payment steps up. These lines have a draw period followed by a repayment period. When the interest-only draw ends and repayment begins, the monthly obligation rises. That is where thin-margin plans get squeezed.
• DSCR is not cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation, and so does your HELOC payment. A rental at 1.20 coverage can still lose money after those costs.

Honestly, the cleanest version of this plan is a short hold. Buy with the HELOC down payment, stabilize the rental, then use a DSCR cash-out refinance to repay the line. Cash-out on standard rentals tops out around 75% LTV, and about 6 months of seasoning is the common expectation, so build that wait into the plan. Short-term rentals use lower ceilings, and short-term rental rules can vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income. Every figure here varies by lender and program, and guidelines, property type, leverage, and credit profile all apply.

One broker-level observation: the files that struggle are usually not short on equity. They are short on documentation. The investor draws the line two weeks before contract, the funds show up as a large deposit, and nobody told the purchase lender. Telling the lender first, and asking what they will count, prevents most of the trouble.

Use It, Think Twice, or Skip It

The pattern is simple. The more cash cushion you hold outside the borrowed money, the better the plan works. For the full picture of how these loans fit together, see Lendmire’s complete DSCR loans guide.
