HELOC to Buy Investment Property for Investors Using Rental Equity

The Quick Read: A HELOC can fund the down payment on a rental, but only when the borrower qualifies personally and the collateral meets strict title and leverage rules, and the line never replaces the purchase loan on the new property. Equity comes from either the investor’s own home or an existing rental, and each path is underwritten differently, subject to lender guidelines.

• On an investment property, the network’s ceiling is 70% combined loan-to-value (CLTV), with lines capped at $500,000.
• A 700 credit score is the hard floor on an investment line, and a score above that buys eligibility, not extra leverage.
• Title must sit with the individual or a revocable living trust. An LLC cannot hold it.
• A HELOC is underwritten on the borrower. A DSCR loan is underwritten on the property’s rent. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

Most investors who ask this question own equity and want to move before a deal slips away. A line in hand means an offer without a financing contingency on the down payment. That is the appeal. The catch is that the line is personal debt, and it sits on top of whatever loan buys the new property. This piece walks through how that works, where it breaks, and when a DSCR loan is the cleaner tool. Availability for these lines runs through Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint.

Key Terms Defined

HELOC: A revolving line secured by property, where the borrower draws, repays, and draws again within the draw period.

CLTV: Combined loan-to-value, meaning all liens on the property added together and divided by its value.

Draw period: The stretch when the borrower can pull funds and pays interest only, before full repayment begins.

Vesting: How title is held, whether by an individual, a trust, or an entity.

DSCR: The ratio of a property’s rent to its full monthly payment, including taxes, insurance, and any HOA dues.

What Is a HELOC, and Can It Buy a Rental?

Yes, with limits. A HELOC is a line that lets you borrow, spend and repay as you go, using your property as collateral. The proceeds can cover a down payment, closing costs, or renovations on the next rental. They do not usually cover the whole price. A separate purchase mortgage normally funds the balance.

Two collateral paths exist:

The home path is more common and has wider leverage. The rental path is narrower. Many large banks decline non-owner-occupied collateral outright, and some cap how many rentals a borrower can own.

How Does Underwriting Treat a Rental-Equity HELOC?

The file is judged on the borrower, not the rent. A HELOC on a rental is underwritten on credit, debt-to-income, and equity. Rent does not drive the decision. DTI maxes out at 50% across the network, with 45% for credit profiles from 600 to 679. The qualifying payment is figured on the interest-only amount at the maximum draw, so every new payment counts against the ratio.

Here is the sequence on a typical file.

1. Pick the collateral. Either the primary home or an existing rental secures the line.

2. Compute equity and CLTV. Line size is property value times the CLTV cap, minus existing liens. Run it with units: on a property valued at 100 units with a 70% cap, a first mortgage worth 50 units leaves a line of at most 20 units. A first mortgage worth 60 units leaves only 10. The 70% is combined, so the line is the remaining slice, not 70% of value.

3. Qualify the borrower. Credit, DTI, and title are reviewed. Credit reports can be no more than 90 days old at closing.

4. Value the property. Investment lines top out at $500,000, so they sit in the automated-valuation lane and commonly close with no traditional appraisal. A borrower can still request a full appraisal.

5. Close, then draw. At least 75% of the line is drawn at closing. Pricing floats and never converts to fixed.

6. Deploy the funds. The money is in hand before the offer. Repaying the balance restores availability on a revolving line.

7. Exit. Many investors use the line as short-term capital, then refinance into a cash-out refinance or DSCR loan to pay it off.

What Structure Does the Line Take?

Investment lines run one structure: a 5-year interest-only draw, then a 25-year fully amortizing repayment. The line can sit in first or second lien position. The minimum line is $25,000, and the minimum subsequent draw is generally $1,000 after closing, with state exceptions.

Primary-residence and second-home lines add a second option, a 3-year draw with a 17-year repayment. A line above $500,000 is primary-residence only, requires a 700 credit profile or better (720 on the longer-runway structure), caps at 75% CLTV, and needs a full appraisal.

Where the General Rule Breaks

Edge cases decide more files than the headline numbers do.

LLC-titled rentals. A deed held in an LLC fails the title gate. The fix is a vesting change, or a DSCR cash-out refinance instead, subject to lender program eligibility. This is the sharpest structural difference from a DSCR loan.

Occupancy class. A duplex where the owner lives in one unit is reviewed as a primary residence. If both units are rented, it is reviewed as an investment property. The CLTV ceiling follows the occupancy actually underwritten, so never assume the higher tier.

Renting out the home. The CFPB’s HELOC booklet notes that renting your home may be prohibited under a line’s terms. House-hackers should read the terms before drawing.

Lender freezes. The same booklet says lenders can freeze or reduce a line if the home’s value falls. If the line is your down-payment source, a freeze mid-search is a real risk.

Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.

Portfolio size. A borrower is limited to three lines, and an investor with more than 15 financed properties is not eligible.

Ineligible property types. Manufactured homes, co-ops, condotels, log homes, and commercial or mixed-use properties are not offered.

Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year path after foreclosure and 4 years after a deed-in-lieu or short sale.

HELOC or DSCR Loan: Which Fits?

They answer different questions. A HELOC asks whether the borrower can carry the debt. A DSCR loan asks whether the property’s rent covers its own payment. Across the wholesale network, most DSCR purchase files land at 75%–80% LTV, with select high-leverage programs reaching 85% at roughly a 700+ score, all subject to lender guidelines. Many programs want around 660 credit. Coverage of 1.00 is where select programs start, and a separate select-lender path goes below 1.00 with leverage and terms adjusted.

DSCR qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. That suits an investor with many properties or limited personal income. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, management, and capex sit outside the ratio. The complete DSCR loans guide covers the full mechanics.

The cleanest combined play is sequencing. Use the HELOC for the down payment, buy with a DSCR loan, then refinance if the line needs retiring. That clears two tests at once: enough equity and enough rental coverage.

Does the Deal Pay? A Stress Test

Run three checks before drawing.

• Coverage on the new property. Rent should cover the new purchase loan with room left over. A ratio near 1.2x leaves more cushion than one sitting at 1.00.
• The added line payment. The HELOC payment is variable and interest-only during the draw. It lands on top of the purchase payment, so the deal must carry both.
• The shock case. Assume a vacancy stretch and a higher line payment at the same time. If the deal only works in the good case, the line is carrying the strategy.

Negative cash flow and foreclosure exposure are the main risks, since the pledged property can be lost if payments stop.

Common Mistakes

• Assuming an LLC can hold the line. It cannot.
• Treating 70% as the line size. It is the combined ceiling, so existing liens come off first.
• Chasing a higher score for more leverage. On an investment line, 700 and 720 both reach the same 70% ceiling.
• Counting projected rent as guaranteed. Underwrite the deal on conservative rent.
• Skipping reserves. Keep cash behind both the line and the purchase loan.

Tax Note

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.
