Doing a HELOC to Buy Investment Property

The Quick Read: A HELOC is a source of cash, not a purchase loan: you borrow against the equity in a home you already own, then use that cash as the down payment on a separate loan, often a DSCR loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The strategy works when the paperwork is sequenced correctly and the rent can carry more than one obligation. It fails when investors assume the line and the purchase loan ignore each other.

• The line must be open, and usually funded, before you go under contract.
• The purchase lender decides whether borrowed funds can count toward the down payment. Many DSCR lenders in Lendmire’s network accept documented line-drawn funds, and some cap the borrowed share.
• DSCR measures rent against the property’s own payment. The HELOC payment sits outside that ratio but still comes out of your cash.
• Borrowed money rarely counts as reserves, so plan for those separately.
• Title matters. Network HELOCs are written to individuals or revocable trusts, not LLCs.

What Doing a HELOC Actually Involves

Doing a HELOC for a rental purchase takes two separate loans and two separate approvals. The first is the line of credit, which is underwritten to you and the home that secures it. The second is the purchase loan, which is underwritten to the rental property.

A home equity line works like a credit card secured by your house. You get a limit, draw what you need, and pay interest on the drawn balance. The first years are an interest-only draw period. Then principal repayment begins, and the payment can step up sharply.

Most investors who do this pull equity from their own primary residence. A smaller group borrows against an existing rental. The collateral is the property that secures the line, and that is where the risk sits. If the line goes unpaid, the lender’s claim is against that home, not against the property you just bought.

The purchase loan is then a conventional mortgage, a DSCR loan, or cash. Investors with several financed properties or self-employed income often choose DSCR. The loan is reviewed on the rent covering principal, interest, taxes, insurance, and any HOA dues, so a stack of existing debt does not crowd the file the way it can on a conventional application.

Lendmire’s complete DSCR loans guide covers how that ratio is built from the ground up.

How Underwriting Treats the Money, Step by Step

Underwriting looks at the line, then the funds, then the property. Each step has its own test, and a file can pass one and fail the next. Here is the sequence that tends to hold up.

1. Open the line first. Lenders generally will not open a new HELOC once you have a purchase pending, so the line comes before the contract. The deposit also needs a paper trail, and an account that has already been funded gives you one.

2. Size the line to the equity. Lenders typically take a percentage of the home’s appraised value and subtract what you still owe. They also weigh income, debts, and credit history. The CFPB’s HELOC booklet explains this formula.

3. Draw the cash and let it settle. Move the draw into your own account so the deposit traces back to the line. The purchase lender will review where the down payment came from.

4. Confirm the purchase program accepts borrowed funds. This is the step that surprises people. Acceptance is program-specific. Across the network, many DSCR lenders accept line-drawn funds when they are documented, and some limit how much of the down payment can be borrowed. Ask before you draw, not after.

5. Underwrite the rental. On a DSCR purchase, most files land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select high-leverage purchase programs reach 85% LTV, with roughly a 700 or better score. Coverage of 1.00 is where select programs start, and stronger ratios open better pricing and leverage.

6. Hold reserves separately. Down payment and reserves are different tests. Reserves commonly run around six months of PITIA, though they vary by lender, leverage, and loan size. A line you owe money on is a debt, not an asset, so plan for reserves from cash that is genuinely yours.

Credit expectations on the purchase side follow the same layered pattern. A 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers.

What the Network’s Own HELOC Looks Like

Lendmire brokers home equity lines through select wholesale partners, and the guidelines differ by occupancy. The two tiers below describe what an investor sees when the line is secured by a rental versus a primary home. Every figure is subject to lender guidelines and full file review.

Several details sit behind that table.

• Investment lines are a two-tier table. A 720 score and a 700 score both reach 70% CLTV, so higher credit buys eligibility rather than extra leverage. Below 700 there is no tier.
• A primary-residence line above $500,000 needs a 700 or better credit profile (720 on the five-year-draw structure), caps at 75% CLTV, and requires a full appraisal.
• Lines may sit in first or second lien position. At least 75% of the line is drawn at closing, and pricing floats through both the draw and repayment periods. It never converts to a fixed structure.
• DTI tops out at 50%, and the line is qualified on the interest-only payment calculated at the maximum draw. That matters because the payment used in qualifying is higher than what you would pay on a small initial draw.

A line on your own home generally gives you the best combination of leverage and cost. Experian’s explainer on HELOCs for investment property notes that a line on a rental is less common and harder to obtain than one on a primary home. That matches what a broker sees across lenders.

Network availability for these lines covers 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the DSCR footprint of 41 markets, including Washington, D.C.

Where the General Rule Breaks

The standard rule says the line supplies cash and the DSCR loan buys the rental. These edge cases bend or break it.

LLC-owned property. A network HELOC must be held by an individual or a revocable living trust. LLCs, corporations, partnerships, and irrevocable or land trusts cannot hold title. If your rental already sits in an LLC, a line against it needs a vesting change first, or a DSCR cash-out refinance may be the cleaner path. Whether a DSCR purchase can then close in an LLC depends on lender program requirements.

Large portfolios. A borrower can carry only three lines, and an owner with more than 15 financed properties is not eligible. The DSCR side has no equivalent personal-income stack, so portfolio investors often run the line on one property and the purchase loan on another.

Self-employed borrowers. The line can be underwritten on documented income under the applicable program, including bank statements, subject to lender guidelines. On an investment line the 700 floor is already higher than the bank-statement minimum, so income documentation is rarely the binding constraint.

Ineligible property types. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible for the network’s HELOCs. DSCR purchase programs in the network likewise do not offer financing on manufactured homes (single- and double-wide), log homes, or barndominiums.

Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.

The line gets frozen. The CFPB’s HELOC brochure says lenders can freeze or reduce a line if the home’s value falls or your finances worsen. A frozen line in the middle of a purchase is a real timing risk, which is another reason to draw before going under contract.

Draw-to-repayment shock. The CFPB’s overview of home equity lines uses a 10-year draw as its example, and warns that falling behind could cost you the home. Network investment lines use a 5-year draw followed by 25 years of full repayment. When the draw ends, the payment can rise sharply, so the exit plan needs to be settled well before that point.

The Two-Payment Problem (and a Worked Scenario)

Clearing 1.00 on a DSCR file is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the ratio, and so does the HELOC payment.

Run the numbers this way. Picture a rental that clears roughly 1.20x on a standard DSCR purchase at 75% LTV. Now add a line payment that raises your total monthly obligations by about a fifth. Coverage on the combined picture falls to roughly 1.00x, and that is before any of the costs the ratio leaves out. The lender may be satisfied. Your bank balance may not be.

There is a second effect that practitioners flag. Because the HELOC funds the down payment, the investor is effectively financed close to 100% on the new purchase. That is not wrong, but it removes the cushion that equity normally provides. If the property sits vacant for a stretch or needs a roof, there is no equity cushion in the deal and only the line behind it.

Compare two investors.

• Investor A holds a rental clearing around 1.35x, with solid personal cash reserves and a modest draw. The combined obligations still leave room.
• Investor B has a rental clearing just above 1.00x and relies on the line for most of the down payment. Coverage is thin on the first payment, and any vacancy turns it negative.

For Investor B, the issue is not the loan type. It is the property or the leverage, and the fix is more equity, a stronger-yielding rental, or a different deal.

A sub-1.00 structure exists through select lenders in the network, with leverage and terms adjusted. It can make sense for a property with a clear appreciation story. It is a poor patch for a deal that only works if the HELOC is doing the heavy lifting.

HELOC vs. the Alternatives

A HELOC is one of several ways to fund the down payment. Which one fits depends on where your equity sits and how long you plan to hold.

The cash-out path deserves a closer look. A DSCR cash-out refinance tops out around 75% LTV across most of the network, and about six months of seasoning is the common expectation. It moves the debt to the rental itself instead of your residence. The tradeoff is that it replaces an existing loan, so it only makes sense if the new terms beat what you have now. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

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.

Key Terms Defined

HELOC: A revolving line of credit secured by the equity in a property, with a draw period followed by repayment.

CLTV: Combined loan-to-value, which adds every lien on the property and divides by its value.

DSCR: Debt service coverage ratio, found by dividing monthly rent by the property’s full monthly payment.

PITIA: Principal, interest, taxes, insurance, and any association dues, which together make up the DSCR payment.

Seasoning: The length of time you have held a loan or funds before a lender counts them.

Reserves: Liquid assets held after closing to cover payments if income stops.

Is Doing a HELOC the Right Move?

For an investor with a strong primary-residence equity position, a rental that clears 1.20x or better, and personal cash to cover reserves, the strategy usually pencils. The investor keeps savings intact, borrows only what the down payment requires, and lets the rent carry the purchase loan.

It flips for the investor who is reaching. If the rental sits near the DSCR benchmark, if your reserves depend on the same line, or if you would be uncomfortable with your home secured against an investment, a DSCR cash-out refinance on an existing rental or a smaller deal may be the better call. Lendmire’s piece Should I Buy Investment Property With HELOC? walks through that tradeoff.
