Can a Home Equity Line Fund an Investment Property Purchase?

The Quick Read: Yes, in most cases: a home equity line of credit (HELOC) supplies cash from equity in a property you already own, and that cash can cover a down payment, closing costs, or rehab, while a separate purchase loan or a cash closing actually buys the rental, provided the purchase lender accepts documented borrowed funds. The line never buys anything by itself. The real questions are how much equity you can reach and whether the purchase loan allows borrowed money in the deal.

• The line must sit on property you already own, usually your primary home.
• On Lendmire’s wholesale network, an investment-property line caps at 70% combined loan-to-value (CLTV) and $500,000.
• Purchase lenders fall into camps on borrowed down payments, so ask before you open the line.
• A DSCR purchase loan looks at the rental’s income, but the line’s payment still hits your real cash flow.

How does a HELOC fit into a rental purchase?

A HELOC and a rental purchase are two separate transactions. The line is secured by a property you already own, and the purchase loan is secured by the rental you are buying. Each lender looks at its own collateral.

You can’t open a line on a rental you haven’t bought yet, because the collateral must exist first. For a first-time landlord that means the primary residence. Yahoo Finance notes that equity in a primary home can fund a down payment on an investment property.

The sequence runs in order:

1. Check your usable equity.

2. Ask the purchase lender how borrowed funds are treated.

3. Open the line and draw the cash.

4. Document the transfer into your account.

5. Close the purchase.

6. Pay the line down, refinance it, or sell.

Skip step two and you can end up with cash the purchase lender won’t count.

Which property should secure the line?

Your primary home usually supports the larger and easier line, while a line on an existing rental is narrower and harder to find. NerdWallet notes that investment-property lines have a smaller pool of lenders and lower borrowing amounts than lines on a primary home. The network’s numbers show the same gap.

The 90% ceiling exists only for a primary residence or second home at a 720-or-better profile. An investment line never goes above 70% CLTV, and a 700 score is a hard floor with no tier beneath it. Credit above 700 buys eligibility, not extra leverage.

Primary-residence lines come in two draw setups. One has a 3-year interest-only draw followed by a 17-year repayment. The other has a 5-year draw followed by a 25-year repayment. Investment lines use the 5-year-draw structure only. A primary line above $500,000 needs a 700 or better score (720 on the 5-year-draw structure), a full appraisal, and a 75% CLTV cap.

Market surveys report that investment-property lines typically want around a 720 score and cap near 80% loan-to-value, per Experian. Those are market-wide figures. The network’s investment ceiling is 70% CLTV.

Title matters too. The property securing the line must be held by you personally or by a revocable living trust. An LLC can’t hold title on these lines, so a rental already deeded to an LLC needs a vesting change or a DSCR cash-out refinance instead, subject to program terms. Lendmire arranges home equity lines in 16 states, a narrower footprint than its DSCR lending across 41 markets, including Washington, D.C.

Will the purchase lender accept borrowed down-payment money?

It depends on the program. Across Lendmire’s wholesale network, programs sit in three camps on borrowed down-payment funds. Some accept documented line proceeds in full. Some cap the borrowed share. Some require part of the down payment to come from cash you didn’t borrow.

Nothing in law stops you from using line proceeds however you like. The constraint is the purchase lender’s guideline. Expect to disclose the source and show paper: the line agreement, the draw confirmation, and bank statements showing the transfer. Lenders review large deposits, so unexplained money creates problems. Borrowing for a down payment is routine, and concealing it is what causes trouble.

Two edge cases come up often:

• A fully borrowed down payment. Almost every dollar of the purchase is then financed, across two loans on two properties. Lenders cap leverage for a reason, and the purchase program’s own limits still apply.
• Reserves. Borrowed funds often can’t count as both the down payment and the reserves. Reserves are a separate test, so the line may need to cover both.

How does a DSCR lender treat the line payment?

A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, so the line’s payment generally stays out of the ratio. DSCR, or debt service coverage ratio, is monthly rent divided by the monthly principal, interest, taxes, insurance, and HOA dues (together called PITIA). 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.

Program rules govern, so confirm how your lender handles it. A conventional investment loan would count the new line payment in your debt-to-income ratio. A DSCR file usually doesn’t.

Here is what the purchase side looks like across the network, as typical ranges and never promises:

• Leverage: most purchases land at 75% to 80% LTV, which means 20% to 25% down. Select high-leverage programs reach 85% LTV with roughly a 700+ score.
• Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
• Credit: most programs want around 660. A 620 floor exists in parts of the network, and 700+ unlocks the strongest leverage tiers.
• Reserves: commonly around 6 months of PITIA, though they vary by lender, leverage, and loan size.
• Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders).

A bigger down payment lowers the monthly payment and can lift the coverage ratio. It never erases leverage caps, credit floors, or reserve rules. The strongest files clear both tests: enough equity and enough rental coverage. The complete DSCR loans guide walks through those tests in full.

One trap deserves its own sentence. Clearing 1.00 does not mean positive cash flow. The ratio compares rent to PITIA only, and repairs, vacancy, management, utilities, capex, and your line payment all sit outside it.

How much can you actually borrow against your equity?

Usable equity is smaller than total equity because lenders cap combined loans, not just the new one. The formula is simple: home value times the allowed CLTV, minus what you owe on the first mortgage.

Run the numbers on an existing rental in percentages. Say its first mortgage equals 50% of the value, and the investment cap is 70% CLTV. That leaves room for a line worth about 20% of the property’s value, assuming the line fits under the $500,000 maximum. A lower score, a higher existing balance, or a value that comes in light shrinks it.

Two other file tests apply. Debt-to-income can run to 50% at most, and 45% for credit profiles from 600 to 679. Lenders review your file on the interest-only payment calculated on the maximum draw. They don’t use the smaller amount you plan to borrow.

At least 75% of the line is drawn at closing. You can’t open a big line and leave it nearly untouched while keeping the cost low. Plan to carry most of it from day one.

Can the lender freeze or shrink the line?

Yes, and an undrawn line is permission, not committed money. The CFPB’s HELOC booklet explains that a lender may freeze or reduce a line if the home’s value falls significantly or your finances materially worsen.

The practical lesson is to draw and close while the file is stable. A line you were counting on at contract may not be there at closing if values drop or your credit changes. Lenders also pull credit reports no more than 90 days before closing, so a new debt or late payment can change the file.

What should you stress-test before drawing?

Model the worst quarter, not the average one. The line’s pricing floats across both the draw period and the repayment period on this network, and it never converts to fixed. Your cost can rise while the rental sits vacant.

Check these before you commit:

• Vacancy. Can you cover the line payment and the purchase loan for several empty months?
• The conversion. An interest-only draw ends and full payments begin. On the 5-year-draw structure, that means a 25-year amortizing payment starting while the rental may still be stabilizing.
• Value risk. If your home loses value, the cushion under both loans shrinks. You have also put your primary residence behind a rental bet.
• Exit. Know whether you will pay down, refinance, or sell, and what triggers each.

This is a genuine toss-up for many investors. Using the line keeps savings liquid, which is real value. It also stacks a second debt on top of the first, which is real risk. A sound plan makes the rental carry itself without depending on the line staying open.

When does it make sense, and what are the alternatives?

It makes sense when you have ample equity, a credit profile at or above the line’s floor, a purchase lender that accepts borrowed funds, and a rental with strong coverage. It doesn’t make sense when the borrowed money would be your only reserve, or when the rent barely covers the loan.

Alternatives deserve a look:

• DSCR cash-out refinance on a rental you own. Cash-out tops out around 75% LTV on standard rentals across most of the network, with about 6 months of seasoning as the common expectation. Select short-term-rental collateral caps lower, around 70% on cash-out.
• Savings. It is the cleanest and the slowest to rebuild. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
