Investment Property HELOC Requirements to Fund a Rental Purchase

The Quick Read: An investment property HELOC can fund a rental purchase only when the line is secured by a property you already own and is drawn before the purchase loan closes, and on Lendmire’s wholesale network an investment-property line requires at least a 700 credit score, caps at 70% CLTV, and tops out at $500,000, subject to lender guidelines.

• The new rental cannot secure its own down-payment line. The collateral is your primary home or a rental you already hold.
• A line on an investment property is a narrow product. A line on your primary home reaches higher leverage.
• The purchase lender reviews the borrowed cash separately. Many DSCR programs accept it toward the down payment but not toward reserves.
• Entity-held properties are a hard stop for this product. An LLC cannot hold title on the line.
• Review details depend on the borrower, the property, and the lender. This is not a commitment to lend.

What Is an Investment Property HELOC, Really?

The phrase covers two different products. Investors use it for a line on their primary home, with the cash going toward a rental down payment. They also use it for a line secured by a rental they already own.

The first is far easier to find. The second exists, but fewer lenders offer it, and its rules are tighter.

Both are home equity lines. A HELOC is an open-end line of credit with a draw period followed by a repayment period. When the home already has a first mortgage, the line sits behind it as a second lien. Pricing on these lines floats and does not convert to a fixed payment.

A HELOC does not replace the purchase loan. It supplies cash. A separate loan still finances the rental itself, and that loan has its own credit, leverage, and property review.

What Are the Investment Property HELOC Requirements on This Network?

An investment line on this network is capped at 70% CLTV and $500,000, and it requires a 700 credit score. Across Lendmire’s wholesale network, the guidelines for a line secured by a rental look like this. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

• Combined leverage: 70% CLTV maximum on an investment property. Credit above 700 does not raise that ceiling.
• Credit: a 700 minimum. There is no tier beneath it.
• Line size: $25,000 to $500,000 on an investment property. Larger lines are primary-residence only.
• Structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing.
• Debt-to-income: 50% maximum. The file is qualified on the interest-only payment at the maximum draw.
• Valuation: a line capped at $500,000 commonly runs on an automated valuation, with no traditional appraisal. A borrower can still ask for a full appraisal.
• Eligible collateral: single-family homes, 2-4 units, PUDs, townhomes, and condos, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural property are not offered.

A line on a primary home works differently. Primary-residence lines can reach 90% CLTV, but only with a 720 or better credit profile. The program floor for those lines is 600. Two draw structures exist there: a 3-year draw with a 17-year repayment, and the 5-year draw with a 25-year repayment.

Market surveys report that investment-property HELOCs can reach 80% combined leverage with a 720 score, per The White Coat Investor. On this network, the investment-line ceiling is 70% CLTV at a 700 minimum.

This product is also offered only in Lendmire’s 16 full-service states. That is narrower than the 41-market DSCR footprint, which includes Washington, D.C.

How Does Underwriting Treat the Line, Step by Step?

Two separate approvals happen here. The line is approved on the collateral, and the rental purchase is approved on its own merits.

1. Choose the collateral. The lender values the home or rental that will secure the line. A primary home is judged on equity, credit, income, and total debts. A rental is judged on equity too, and the lender also looks at how the property is owned and used.

2. Measure combined leverage. The lender adds the first mortgage and the new line, then divides by the property value. That CLTV must fit under the ceiling for the occupancy type.

3. Check credit and debt load. A single-bureau credit score keyed to the primary wage earner drives the file. Debt-to-income is capped at 50%, and 45% for scores from 600 to 679. A ratio above 45% requires a 680 minimum.

4. Confirm title. The line must be held by the individual borrower or a revocable living trust. Property deeded to an LLC, corporation, partnership, or irrevocable or land trust cannot secure it.

5. Draw the cash. Most of the line is drawn at closing. The funds then sit in the borrower’s account.

6. Document the funds for the purchase. The purchase lender wants to trace the money from the line to the account to the escrow.

7. Underwrite the rental separately. The purchase loan compares the new property’s rent to its own payment (principal, interest, taxes, insurance, and any HOA dues). The line is a personal obligation outside that math.

A larger down payment shrinks the new mortgage and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

How Does the Purchase Lender Treat Borrowed Down-Payment Cash?

Many DSCR programs in the network accept documented borrowed funds toward the down payment and closing costs. They generally exclude borrowed funds from reserves. Some programs cap the borrowed share. The strictest overlays want part of the down payment to come from unborrowed money. A fully borrowed down payment is a problem on its own with some programs.

Reserves vary by lender, leverage, loan size, and transaction type. About six months of PITIA is common. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to about nine months.

On the purchase side, most DSCR files on this network land at 75% to 80% LTV on a purchase of a standard rental. Select programs reach 85% LTV with roughly a 700 score. Credit floors start at 620 in parts of the network, most programs want around 660, and 700 or better opens the strongest leverage tiers.

Coverage works the same way. A 1.00 ratio is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.

Picture an investor whose home equity sits well under the line’s CLTV ceiling. She draws on the line and buys a rental at 75% LTV that clears roughly 1.2x on coverage. The purchase loan sees only the new property’s rent and payment. The line payment never enters that ratio, but it still lands on her personal cash flow every month. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Clearing 1.00 is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. A borrower who carries a variable-rate line payment on top of a thin-coverage rental can feel the squeeze even with an approved file. Tax treatment varies; consult a qualified professional.

Where Do the Rules Break?

The general rule is simple: borrow against what you own, then buy what you want. Several edge cases bend it.

The home becomes a rental. The CFPB’s overview of home equity lines warns that falling behind on a HELOC can cost you the home. Line agreements may also restrict renting the property out. Read the occupancy terms before moving out of a home that secures a line.

The line shrinks. Lenders can cut or freeze a line if the home’s value drops, as the CFPB’s HELOC booklet explains. An investor counting on later draws should not plan around cash the lender can withdraw. Because at least 75% of the line is drawn at closing, the first draw does most of the work.

The rental sits in an LLC. An LLC cannot hold title on this product. The property needs a vesting change, or the investor can pursue a DSCR cash-out refinance instead. Cash-out on a standard rental tops out around 75% LTV, with about six months of seasoning commonly expected. DSCR loans to LLC-titled borrowers are subject to lender program eligibility.

The investor already owns many properties. A borrower is limited to three lines. An investor with more than 15 financed properties is not eligible.

The property type is out of scope. A property listed for sale, or listed within the last 60 days, is ineligible in several states. Manufactured homes, log homes, condotels, and mixed-use buildings are not offered on the line. Manufactured homes, log homes, and barndominiums are also not offered under the network’s DSCR programs.

Credit history is damaged. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, a foreclosure needs seven years. A deed-in-lieu, pre-foreclosure, or short sale needs four.

Which Route Fits Which Investor?

The primary-home line fits an investor with a lot of home equity, a strong score, and a deal that clears coverage on its own. The rental line fits a smaller group.

Some investors keep the home out of the deal. That is a risk-preference choice. The primary-home line gets higher leverage, but it puts the family residence behind the rental purchase.

A cash-out refinance on an existing rental is the other route. It avoids a second lien and can hold title in an entity, depending on program guidelines. It also resets the existing loan. The tradeoff is real in both directions, so run both versions before drawing anything.

Key Terms Defined

CLTV (combined loan-to-value): the first mortgage plus the line, divided by the property’s value.

Draw period: the stretch when you can borrow from the line, usually paying only interest.

Repayment period: the stretch after the draw ends, when the balance amortizes.

PITIA: the full monthly housing obligation, covering principal, interest, taxes, insurance, and association dues.

DSCR: the debt service coverage ratio, found by dividing monthly rent by PITIA.

Vesting: how title to a property is held, whether by an individual, a trust, or an entity.

Source of funds: the documented trail showing where your down payment came from.
