Investment Property HELOC Requirements on Your Primary Home to Buy a Rental

The Quick Read: A home equity line on your primary residence can supply cash for a rental purchase, but it only clears when your credit, debt-to-income ratio, combined leverage, and property type all fit the program, and a separate loan still has to buy the rental itself.

• A primary-residence line reaches 90% combined loan-to-value only at a 720-or-better credit profile, subject to lender guidelines.
• The program credit floor is 600, and debt-to-income tops out at 50%.
• Lines run $25,000 to $750,000, and at least 75% of the line is drawn at closing.
• The rental’s lender sets its own down payment, reserves, and coverage tests.
• Pricing floats during both the draw and repayment periods and does not convert to fixed.

What the Line Lender Checks

The line lender underwrites you and your home, not the rental. Credit, debt-to-income, combined leverage, valuation, property type, and how title is held decide the file. The rental never enters the equation, so rent does not help you qualify for the line.

Credit. The program floor is 600. The lender pulls a single-bureau score keyed to the primary wage earner, and the report can be no more than 90 days old at closing. No rescores are allowed. Housing history and tradeline standards vary by program. One structure asks for two tradelines seasoned 12 months or one seasoned 24, with a clean mortgage history across all financed properties.

Debt-to-income. The ceiling is 50%. It drops to 45% for credit profiles from 600 to 679, and anything above 45% needs a 680 minimum. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. That detail catches borrowers who intend to draw a small amount.

Derogatory events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program. One path seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4. The other declines the history entirely, regardless of age.

Valuation. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. A higher combined leverage target can trigger a secondary valuation, and you can request a full appraisal in any case. Every line above $500,000 requires a full appraisal.

Property and title. Eligible collateral includes single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Modular factory-built homes are eligible on one program only. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible.

Title must sit with you individually or in a revocable living trust. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot hold title on these lines.

How Much Can the Line Be?

The ceiling is a combined loan-to-value test. Combined leverage adds your first mortgage balance to the new line and compares the total to home value. On a primary residence, the ceiling reaches 90% only at a 720-or-better profile. Lower credit tiers sit below that, and the lender confirms your tier at review.

Run it as modeled assumptions, not market data. Say the home appraises at 100 units of value, and the first mortgage is 60% of that value. A 90% ceiling leaves 30% of value as the maximum line. A 75% ceiling, which applies to lines above $500,000, leaves 15%. The gap between those two outcomes is why the credit tier and line size matter before you plan a down payment.

A line above $500,000 is for primary residences only. It requires a credit profile of 700 or better (720 on the longer-runway program), caps at 75% combined leverage, and needs a full appraisal. The longer-runway program is the structure with the 5-year interest-only draw and 25-year repayment described below. A borrower can hold up to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower who owns more than 15 financed properties is not eligible.

How the Line Itself Is Built

The line is a standalone product in first or second lien position. Two draw structures exist on primary residences. One runs a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other runs a 5-year draw followed by a 25-year repayment. Tennessee shortens both structures, to 3 and 12 years and 5 and 10 years. Any figure quoted to you should carry the structure it belongs to.

Two program names appear here. The higher-leverage program is the structure with the larger exposure cap and the higher leverage tiers. The longer-runway program is the 5-year draw structure with the tighter exposure cap.

Three mechanics matter for a rental buyer.

1. At least 75% of the line is drawn at closing. You cannot open the line and leave it at zero. Plan for interest-only payments on most of the line from day one.

2. Pricing floats through the draw and the repayment period and never converts to fixed on this network. The CFPB’s HELOC explainer notes that HELOCs usually carry a variable rate, and that some plans elsewhere in the market allow a fixed-rate conversion. Do not assume that option exists here.

3. Monthly payments rise when repayment starts. The same CFPB page says payments are often significantly higher once the draw period ends and amortization begins.

After closing, the minimum subsequent draw is $1,000 (Texas is $4,000) under the longer-runway program. Availability is limited to Lendmire’s 16 full-service states, a narrower footprint than the DSCR side of the business.

Where the Rental Loan Fits

The line produces cash. A separate loan buys the rental. Most investors in this position use a DSCR purchase loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire arranges those loans across 41 markets, including Washington, D.C., through a wholesale network. The complete DSCR loans guide covers how the ratio is built.

Typical purchase leverage on the DSCR side is 75% to 80% LTV, or 20% to 25% down. Select high-leverage 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. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Credit floors run from 620 in parts of the network to about 660 on most programs, with 700 and up unlocking the strongest tiers. Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA.

The sequence matters. Open the line before you contract. The draw, the deposit into your own account, and the closing statement make a clean paper trail. Borrowed funds are a known source that the purchase lender then reviews. Programs differ on whether they count toward the down payment. Some accept them. Others want part of the down payment from seasoned funds of your own, or want reserves held separately as unborrowed cash. Ask before you draw, not after.

DSCR compares rent to the rental’s own PITIA. The ratio does not count your line payment. Clearing 1.00 is also not the same as positive cash flow, because repairs, vacancy, management, utilities, and capex sit outside the calculation. You pay the line out of your own pocket if the rental runs short. A larger down payment shrinks the purchase loan and can lift the ratio, but it does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

Three Ways to Fund the Purchase

The first row is the common structure. The second means borrowing close to the full price with the line, then refinancing into a DSCR cash-out later. The cash-out ceiling on most standard rentals is about 75% LTV, and about 6 months of seasoning is the common expectation. That refinance exit is a plan, not a promise. The new loan has to meet its own tests when you need it.

The Line on the Rental Instead

A line secured by an investment property follows tighter rules. The maximum is 70% combined leverage, with no tier above it. The minimum credit score is 700, and 700 and 720 both reach the same 70% ceiling, so a higher score buys eligibility rather than leverage. The line caps at $500,000 and uses the 5-year draw, 25-year repayment structure only.

Because the line caps at $500,000, it falls in the automated valuation lane. It commonly closes with no traditional appraisal. Bank-statement income is not the binding constraint, since business deposit analysis needs a 680 and investment already floors at 700. Foreclosure-family history follows the 7-year and 4-year seasoning path.

The title rule is the sharpest difference from a DSCR loan. A rental already deeded to an LLC cannot take one of these lines as it stands. It needs a vesting change, or a DSCR cash-out refinance instead.

Where the General Rule Breaks

Title in an entity. A line on your primary needs title in your own name or a revocable trust. If you moved the home into an LLC for asset-protection reasons, the line is off the table until that changes.

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

Homestead states. A Texas primary residence is a homestead and caps at 80% combined leverage. It carries a 12-day waiting period, a one-lien-at-a-time rule, and 12-month seasoning. Second homes and investment properties there are treated as non-homestead transactions. Texas properties are also limited to 10 acres.

Credit-dependent caps. New Mexico and Ohio apply a combined leverage cap that depends on the credit profile. A profile under 640 is limited to a single-family residence with a clean 12-month housing history under the longer-runway program.

Ineligible collateral. Manufactured homes, log homes, and barndominiums are not offered on the DSCR side of the network either.

Agreement restrictions. Some line agreements restrict business-purpose use. Read yours before assuming rental funding is permitted.

Stress-Testing Before You Draw

Your primary home secures the cash your rental needs. If the rental sits vacant, the line payment and the rental loan payment both come due, and the line is the one that can put your house at risk. The CFPB’s HELOC brochure lists home at risk as a yes for this product.

Run four tests before you commit:

1. Vacancy. Can you carry both payments with the rental empty?

2. Floating pricing. Can you carry the line if payments rise month to month?

3. Repayment step-up. Can you carry the higher payment when amortization begins?

4. A repair bill. Where does the cash come from if the roof fails in year one?

An investor who can pass all four with their own income is positioned differently from one who needs the rent to cover the line.

Prepayment terms matter too. A DSCR loan can carry a prepayment structure that stretches your refinance exit beyond the timeline you planned.

Key Terms Defined

Equity: your home’s value minus what you owe on your mortgage.

Combined loan-to-value (CLTV): your first mortgage balance plus the new line, divided by the home’s value.

Draw period: the stretch when you can borrow against the line and pay interest only.

Repayment period: the stretch after the draw ends, when payments include principal and rise.

DSCR: the rental’s monthly rent divided by its own PITIA, the ratio the purchase lender reviews.

PITIA: principal, interest, taxes, insurance, and any association dues.
