Investment Property HELOC Options to Buy a Rental Property

The Quick Read: A home equity line can supply the down payment on a rental, but it never buys the property by itself. You borrow against a property you already own. A separate purchase loan, often a DSCR loan, then finances the new one. The line comes first, and the purchase lender decides how the borrowed cash counts.

• On an investment property, a line through Lendmire’s network tops out at 70% combined loan-to-value (CLTV) and $500,000, with a 700 credit floor. Subject to lender guidelines.
• On a primary residence, a line can reach 90% CLTV only at a 720-or-better credit profile.
• Title must sit in your own name or a revocable living trust. An LLC cannot hold title on the line.
• The line’s payment is not part of the DSCR ratio, but you still have to pay it every month.

Most investors who ask about this want one answer: which property do I borrow against, and what does the next loan think of that cash?

What a HELOC Does and Does Not Do in a Rental Purchase

A HELOC creates cash. It does not create a purchase approval. You still need a loan or cash to close on the rental, and that loan has its own down payment, reserve, and source-of-funds rules.

The collateral has to be something you already own. You cannot open a line against the rental you are about to buy, because it is not yours yet. That leaves two real paths:

• Path one: a line on your primary home. The draw becomes part of the down payment on the rental.
• Path two: a line on a rental you already own. The draw funds the next purchase, and the existing rental carries the risk.

Path one is the most common pattern we see, mainly because primary-home lines come with higher leverage and wider lender availability. Path two works too, but fewer lenders write it.

A quick note on the loan that buys the property. 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. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The equity line, by contrast, is reviewed on you and your equity.

How Underwriting Treats an Investment Property Line, Step by Step

Here is the sequence an equity line on a rental goes through in our wholesale network. Treat the figures as program ranges, not promises.

1. Combined leverage is measured. The lender adds every lien on the property and compares the total to its value. On an investment property, the ceiling is 70% CLTV, with no tier above it. A first mortgage stays in place, and the line sits in second position. A line can also stand alone in first position if the property has no mortgage.

2. You get qualified, not the rent. The lender reviews your credit, income, and debts. On an investment property, 700 is the minimum credit profile and a hard floor. Credit above 700 buys eligibility, not extra leverage, because both the 720 and 700 tiers reach the same 70% CLTV. Debt-to-income (DTI) tops out at 50%. The lender calculates it on the interest-only payment for the maximum draw, not on what you actually borrow. That detail trips up many files.

3. The property is valued. Because an investment line caps at $500,000 and full appraisals begin only above that amount, an investment line sits in the automated-valuation lane. It commonly closes with no traditional appraisal. You can request a full appraisal in any case.

4. The line closes and funds. At least 75% of the line is drawn at closing. That means you start paying on most of the balance on day one, not on the cash you eventually use. An investment line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats during both periods and never converts to fixed.

5. The purchase loan is a separate approval. Most purchase programs want to see the cash moved into your account and the new line’s payment counted in your debts. Whether borrowed funds count toward the down payment is that lender’s call. Get the answer before you go under contract. A written source-of-funds ruling on the front end saves a lot of grief.

6. You stabilize, then pay down or refinance. The usual plan is to buy, rent the property, and then pay the line down or replace it with longer-term financing. Paying it down restores availability for the next deal.

The draw-and-repay structure is standard for equity lines. The Consumer Financial Protection Bureau explains that you borrow during a draw period, which could last 10 years, then enter a repayment period when you can no longer borrow. It adds that monthly payments often rise significantly in repayment. Experian notes that draw periods typically run five to 10 years and that some lines carry a balloon payment at the end of the draw. Check the actual terms in your loan documents before you rely on either description.

The Three Main Options Side by Side

Three structures cover most of what investors actually do. Each puts a different asset at risk.

The ceilings above apply to the occupancy named in each row. The 90% figure belongs to primary-residence lines only. It requires a credit profile of 720 or better, and it is not the number to plan around for an investment property.

Option 1: A Line on Your Primary Home

This is the cleanest path when you have meaningful equity in your house. Lines on a primary residence offer the widest leverage and the most flexibility. Two draw structures exist: a 3-year interest-only draw with a 17-year repayment, and a 5-year draw with a 25-year repayment. Pick the one that fits how long you plan to carry the balance.

The tradeoff is blunt. Your home now backs a rental. If the rental sits vacant, the line still comes due. Many investors treat the home as the last asset they want exposed, and that instinct is sound.

Option 2: A Line on a Rental You Already Own

This path keeps the risk inside your investment portfolio. The line runs 70% CLTV at most, up to $500,000, for a borrower with at least a 700 credit profile. The rental must be a single-family home, a 2-4 unit property, a PUD, a townhome, or a condominium, including non-warrantable condos.

Title is the catch. Fee simple or leasehold must be held by you individually or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. Plenty of investors hold rentals in LLCs for liability reasons, so this rules out a lot of files. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.

Option 3: DSCR Cash-Out Refinance, Then Buy

If your existing rental is in an LLC, or the first mortgage is not worth keeping, a DSCR cash-out refinance often fits better. It replaces the first lien instead of adding a second one. Cash-out tops out around 75% LTV across most of the network on a standard rental, with about six months of seasoning as the common expectation. Seasoning is the waiting period a lender wants between buying a property and refinancing it.

The cash-out path is one fixed loan rather than a floating line, and it works inside a business-purpose structure. The cost is that you give up the existing first mortgage, and you may take on a larger balance than you planned.

How the Purchase Loan Sees This

Once you have the cash, the DSCR purchase loan takes over. Most purchase files land at 75% to 80% LTV on the purchase, meaning 20% to 25% down. Select programs reach 85% LTV with 15% down, generally with a score around 700 or better.

Coverage is where many investors misread the math. A 1.00 DSCR is where select programs start, not a universal standard. Stronger ratios open better pricing and leverage. Separately, a select-lender path takes coverage below 1.00 with leverage and terms adjusted. Those are different programs, not one program with a moving floor.

DSCR compares rent to the full monthly obligation of principal, interest, taxes, insurance, and any association dues, called PITIA. It does not include the payment on your equity line. It also does not account for repairs, vacancy, management, utilities, or capital expenses. A deal can clear 1.00 and still lose money after those costs. Never confuse a passing ratio with positive cash flow.

Credit and reserves matter here too. Most programs want a score near 660, with a 620 floor in parts of the network and 700-plus unlocking the strongest leverage. Reserves vary by lender, leverage, loan size, and transaction type. Roughly six months of PITIA is common, and loans above $1,500,000 typically step up to about nine months. Whether borrowed money can count toward those reserves is the purchase lender’s decision as well.

Where the General Rule Breaks

The pattern above covers most files. These edge cases break it.

• LLC-owned rentals. An LLC cannot hold title on the line. You need a vesting change first, or you go the DSCR cash-out route.
• Listed for sale. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
• Property types. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and agricultural zoning are not offered on the line. On the DSCR side, manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network.
• Portfolio size. A borrower can hold only three lines at once. An investor who owns more than 15 financed properties is not eligible.
• Where it is available. The equity line is offered in Lendmire’s 16 full-service states only: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the 41-market DSCR footprint, which covers 40 states plus Washington, D.C.
• Credit history. A bankruptcy needs four years of seasoning from discharge or dismissal. Investment files follow a seven-year seasoning path for foreclosure and four years for a deed-in-lieu, pre-foreclosure, or short sale.
• Draw end. If the line is still drawn when repayment starts, the payment can rise sharply. This matters most on a long hold.

The size cap deserves a mention. Any line above $500,000 is primary-residence only, caps at 75% CLTV, and requires a full appraisal. An investment line never reaches that tier.

What a Deal Looks Like in Practice

Picture an investor who owns a primary home with solid equity and wants a duplex. The investor opens a line on the home. The line draws at least 75% at closing, so interest-only payments start on most of the balance immediately. The investor moves part of that cash toward the down payment and keeps a cushion for reserves.

Then the DSCR purchase loan goes through underwriting. Say the loan is 75% LTV and rent covers the payment at roughly 1.2x. That ratio looks healthy. It leaves out the line’s payment entirely. A real cash-flow check adds the line’s payment, repairs, vacancy, and management to the picture. If rent covers all of that, the deal holds up. If it only works on the DSCR line, the investor is subsidizing the rental from a paycheck. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

Now stress the numbers. Pricing floats on the line and the interest-only payment rises when pricing moves. A DSCR purchase loan with a fixed term does not. So the combined payment can drift upward with only half the stack. Model the line at a higher payment than today’s before you commit.

Next, consider the exit. The 5-year draw gives you time to stabilize, but it ends. Plan to pay the line down, or refinance the rental into longer-term financing, before repayment begins.

Who Should Skip This

Skip it if the new rental only works with 100% financing. A line plus a purchase loan can leave you with almost no equity in the new property. That is a thin cushion for a vacancy or a repair bill.

Skip it, too, if the home is your only meaningful asset and you cannot carry two payments for several months without rent. A rental that sits empty will test that quickly. Many investors do better saving a larger down payment or buying a smaller property. A larger down payment lowers the monthly payment and can lift the DSCR, but it never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
