Best Investment Property HELOC Program With a Twenty-Year Repayment Term

The Quick Read: A twenty-year repayment term is not what an investment-property line uses across Lendmire’s wholesale network. Investment lines run a 5-year interest-only draw, then a 25-year repayment. Which program is best for your situation depends on draw length, leverage, credit, and title.

• Investment-property lines cap at 70% CLTV (combined loan-to-value), with a 700 minimum credit score, subject to lender guidelines.
• The structure is a 5-year draw and a 25-year repayment. That is a 30-year line, not a 20-year one.
• Line size runs from $25,000 to $500,000 on an investment property.
• The line is sized on you (credit, income, equity), not on the rent.
• LLC-owned rentals do not fit this product, so title matters before anything else.

The twenty-year figure still deserves a straight explanation. It is the repayment length many people see on home equity lines, and it gets applied to rentals by habit. Below, you will see where it comes from, what the investment-line version looks like, and how to choose between a line and a rent-based loan.

Key Terms Defined

HELOC: a home equity line of credit, which is a revolving credit line secured by a property you own.

Draw period: the window when you can borrow against the line, often with interest-only payments.

Repayment period: the phase after the draw ends, when no new borrowing is allowed and the balance pays down.

CLTV: combined loan-to-value, meaning your first mortgage plus the new line, divided by the property’s value.

Amortization: paying a balance down on a schedule, so each payment includes principal.

Lien position: whether the line sits first or second in line behind other loans on the property.

DSCR: debt service coverage ratio, meaning monthly rent divided by the property’s monthly payment (principal, interest, taxes, insurance, and any HOA dues).

How Does a HELOC Work in Two Phases?

A HELOC has a borrowing phase and a payoff phase. During the draw, you pull money up to your limit and often pay interest only. After the draw ends, the line closes to new borrowing and every payment includes principal until the balance reaches zero.

Total life of the line is the draw plus the repayment. A 10-year draw with a 20-year repayment is a 30-year line. So is a 5-year draw with a 25-year repayment. The two behave very differently, because a shorter draw means principal starts paying down sooner, over a longer runway.

This is where the word term causes trouble. Some lenders mean the whole life of the line. Others mean one phase. Ask which one is on the page before comparing two programs.

Pricing on the lines Lendmire’s network places floats through both phases, and it never converts to a fixed amount. At least 75% of the line is drawn at closing. Your payment can therefore shift even when you borrow nothing more.

What Does an Investment-Property Line Look Like on This Network?

On an investment property, the line is a standalone loan in first or second lien position. It runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. No shorter structure exists for investment collateral. That is the 5/25 structure.

The network also offers a 3-year draw with a 17-year repayment, the 3/17 structure. That one totals twenty years, and it is available only on primary residences and second homes. If you were hoping for a twenty-year repayment on a rental, it does not exist here. A twenty-year total life on a rental line is not offered.

Here is how the investment line compares with the primary-residence version, per Lendmire’s network guidelines. Figures are typical ranges and subject to lender guidelines and full file review.

Credit above 700 does not buy more leverage on a rental. A 720 and a 700 both reach 70% CLTV. Below 700, there is no tier at all.

NerdWallet confirms that rental lines exist but are offered by fewer lenders and carry stricter requirements than primary-home lines. It reports a market-wide ceiling of 80% at best, with many lenders below 70%. On this network, an investment line tops out at 70% CLTV.

Why Does Twenty Years Show Up So Often?

Twenty years is the common repayment length on consumer home equity lines. The CFPB says lenders often set a schedule to repay the full balance over ten or 20 years. It also warns that monthly payments are often significantly higher once repayment starts, and that some plans demand the whole balance at once.

That pattern describes homeowners borrowing against a primary residence. Rentals sit in a stricter box. The twenty-year number follows people into rental searches because the same product names get used for both.

Do not let the repayment length drive the decision on its own. Five things set the outcome together: draw length, repayment length, how pricing floats, the lender’s renewal rights, and the CLTV ceiling. A 25-year repayment spreads principal over more years, which lowers the monthly step-up. The tradeoff is more total interest over a longer life.

Is the Line Sized on You or on the Rent?

It is sized on you. A HELOC is underwritten on your credit, income, and debt-to-income ratio (DTI), plus the equity in the property. Rent coverage does not enlarge the line. Whether rental income counts toward your income depends on the lender’s guidelines.

On this network, DTI tops out at 50%, and it drops to 45% for credit profiles between 600 and 679. The test uses the interest-only payment calculated on the maximum draw, so a large line tests as a large payment even if you only plan to draw part of it.

Valuation is usually simple. An investment line caps at $500,000, and full appraisals begin only above that size. An investment line is therefore commonly valued with an automated model and no traditional appraisal, though you can request a full appraisal in any case.

A DSCR loan reverses all of this. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Our complete DSCR loans guide walks through that math. If your personal DTI is stretched but the rent is strong, the rent-based path may fit better than a line.

Where the Rules Break: Title, Property Type, and Portfolio Size

Most files fall apart on title. The line must be held by you as an individual or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a different product. DSCR loans can often close in an LLC, subject to program terms, which is the sharpest structural difference between the two.

Property type is the next filter. Eligible: single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Not offered: manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning.

Then there is portfolio size. A borrower is limited to three lines, with combined exposure caps that vary by program. An investor with more than 15 financed properties is not eligible.

Credit history has seasoning rules too. A bankruptcy needs 4 years from discharge or dismissal. Investment files follow a 7-year path for foreclosure and a 4-year path for a deed-in-lieu, pre-foreclosure, or short sale. Credit reports must be no more than 90 days old at closing.

Availability is narrower than the DSCR footprint. Lendmire places these lines in 16 full-service states, while its DSCR investor programs cover 41 markets, including Washington, D.C.

How Do You Judge the Best Program for Your Situation?

The best program is the one whose structure matches your hold plan and your title. No single lender or structure wins for everyone. Lendmire is a mortgage broker, so it shops multiple wholesale lenders and matches your scenario to a program, rather than pushing one product.

Score any line on these criteria:

• Draw length versus your plan. A rehab-and-refinance plan needs a short runway. A long hold needs one you can afford at repayment.
• Repayment length. A longer repayment lowers the step-up but adds interest over time.
• Leverage. The ceiling here is 70% CLTV on an investment property, so check that your equity clears it after your first mortgage.
• Title. Individual or revocable trust only.
• Credit. 700 is a hard floor.
• Exposure. Count your existing lines and financed properties.

How Do You Stress-Test Rent Against the Payment Step-Up?

Test the rental at repayment, not at the draw. Interest-only payments flatter the early years. The real question is whether the property still works once principal starts.

Run the test in five steps:

1. Start with your current coverage on the first mortgage alone, meaning rent divided by that payment.

2. Add the line’s payment at your planned draw size, using the repayment-phase payment, not the interest-only one.

3. Recompute coverage against the combined payment.

4. Subtract your real costs: repairs, vacancy, management, utilities, and capital expenses. DSCR leaves all of these out, and clearing 1.00 is not the same as positive cash flow.

5. Repeat with the line fully drawn.

Here is a modeled example. Say a rental covers its first mortgage at 1.30x. A line payment equal to 30% of that first-mortgage payment drops combined coverage to 1.00x, before any operating costs. The same line fully drawn takes you below 1.00x. If that happens, shrink the draw, wait for rents to rise, or look at a rent-based refinance instead.

Remember also that a line typically adds a second lien to the rental and must generally be paid off when you sell. It is a poor fit for long-hold assets unless the repayment math holds on its own.

Line or Rent-Based Loan?

If you need a large sum relative to your equity, or you would rather be underwritten on the property, a DSCR cash-out refinance is the stronger comparison.

A DSCR cash-out typically expects about 6 months of seasoning and strong coverage ratios. Select programs start at 1.00, and 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 around 660 for most programs, with 700+ unlocking the strongest leverage tiers.

If your goal is to keep your existing first mortgage untouched, a standalone line can make sense. Lendmire’s piece Best Investment Property HELOC Program Without Restarting Your Mortgage Term covers that angle. The tradeoff is a smaller line and lower leverage.
