HELOC Interest-Only Payment Requirements During the Draw Period

The Quick Read: Interest-only payments are common during a HELOC draw period, but nothing makes them mandatory, because the plan’s contract decides whether you owe interest alone or interest plus principal. On the lines Lendmire arranges through its wholesale network, the draw period runs 3 or 5 years, and the balance stays flat until repayment starts.

• The draw-period minimum is a contract feature. Some plans charge interest only, and others build in a slice of principal.
• Interest-only never shrinks the balance. Whatever you owe on the last day of the draw is what gets repaid.
• Payments float with the index, so an interest-only payment is not a fixed payment.
• On the network’s lines, at least 75% of the line is drawn at closing, so the interest-only payment starts out sizable.
• Lenders review your file on the interest-only payment at the maximum draw, not on what you hope to borrow.

What Interest-Only Means on a HELOC

A HELOC has two phases. During the draw period you can borrow against the line, and the required payment is small. During the repayment period you can’t borrow anymore, and the payment covers principal plus interest.

“Interest-only” describes the first phase. Each month you pay the interest that built up on your drawn balance, and nothing goes toward principal. The interest is charged on what you’ve borrowed, not on the full credit limit.

The formula is simple. Take your drawn balance, multiply it by the annual interest percentage, and divide by 12. Double the balance and the payment doubles. Double the percentage and the same thing happens. That is the whole mechanism.

Draw periods vary by lender. Experian reports that the draw period typically lasts 10 years and that borrowers may be expected to pay only accrued interest during it. That is a market-wide description. On the equity lines Lendmire places for investors, the draw runs 3 or 5 years, which is much shorter. The next section covers how those lines are structured.

How Lenders Underwrite the Interest-Only Payment

Lenders review your file on the payment you will actually owe at the line’s maximum draw. Across the network, the payment used for qualifying is the interest-only payment calculated on the full drawn amount. They then compare it to your personal income.

That comparison is your debt-to-income ratio, or DTI, which is your monthly debts divided by your monthly gross income. Here is how the network treats it, subject to lender guidelines:

• The maximum DTI is 50%.
• For credit profiles from 600 to 679, the ceiling drops to 45%.
• Anything above 45% requires a 680 minimum credit profile.

Credit is pulled with a single-bureau score tied to the primary wage earner. The report can be no more than 90 days old at closing.

This is where a HELOC differs sharply from a DSCR loan. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC is reviewed on you: your credit, your income, and your other debts. The two products answer different questions. If you want the investor-loan side, the complete DSCR loans guide walks through it.

Draw Structures on Lendmire’s Network

Lendmire is a broker. It arranges equity lines through select wholesale partners and is never the lender. Those partners run two programs, and each has its own draw and repayment structure. This article calls them the 3-year-draw program and the 5-year-draw program. The 5-year-draw program is the longer-runway option.

Two points matter here. First, investment-property lines run only on the 5-year draw and 25-year repayment structure. Second, a figure quoted for one program applies only within that program’s terms. Don’t mix the two.

Pricing floats through both the draw and the repayment period on both programs. It does not convert to a fixed payment. Tennessee shortens both structures, to 3 years then 12 on the first program and 5 years then 10 on the second.

Here are the leverage ceilings, which depend on how you use the property. Every figure is subject to lender guidelines and full file review.

• Investment property: the ceiling is 70% combined loan-to-value (CLTV) with a 700 minimum credit profile, on lines up to $500,000.
• Primary residence: the ceiling steps up with credit. A 90% CLTV appears only at a 720-or-better profile, on lines up to $500,000.
• Second home: a 90% CLTV also requires 720 or better, with a 640 minimum credit profile and lines up to $500,000.

Line sizes run from $25,000 to $750,000, with a $10,000 floor in Michigan. A line above $500,000 is primary-residence only. It needs a credit profile of 700 or better (720 on the 5-year-draw program), caps at 75% CLTV, and requires a full appraisal. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal.

These lines are available in 16 full-service states, which is narrower than Lendmire’s 41-market DSCR footprint that includes Washington, D.C.

Required, Optional, or Unavailable?

You can’t answer this from a headline. You answer it from the plan’s own paperwork. There are three realities:

1. Interest-only is built in. The minimum payment is accrued interest and nothing more. You may pay extra, but you don’t have to.

2. Principal is built in. The minimum includes some principal, often as a percentage of the balance with a dollar floor.

3. Interest-only is the minimum, but the structure limits you. An initial draw requirement or a short draw period changes how useful it is.

The CFPB’s HELOC booklet confirms the split. It says some plans set a minimum payment that includes some principal plus interest. It also says that principal portion typically doesn’t repay the balance by the end of the term. Other plans allow interest-only payments during the draw period, so nothing goes toward principal. The booklet adds that lenders must disclose the payment terms and transaction requirements, such as minimum draws.

So read the disclosure. Look for the draw length, the repayment length, and the minimum payment formula. Those three items tell you more than any article can.

Where the General Rule Breaks

Interest-only is a common feature, and every common feature has exceptions. Here are the ones that catch investors.

Required draws at closing. On the network’s lines, at least 75% of the line is drawn at closing. “I only pay interest on what I use” is true of the interest charge. But when most of the line is used on day one, that benefit shrinks. The CFPB’s Ask page lists an initial advance at setup as a feature of some plans. It also lists minimum amounts per draw and minimum outstanding balances. After closing, the network’s minimum subsequent draw is $1,000, except in Texas, where it is $4,000.

A payment that moves. Interest-only does not mean fixed. The CFPB booklet notes that on a variable-rate plan, payments can change even if you don’t draw more. It also flags temporary introductory pricing, so the payment can jump before the draw period even ends.

A line that can be reduced or frozen. The same booklet notes that a lender may act when its security interest is impaired. Falling property values or worsening finances can trigger it. Don’t plan a rehab around money you can’t count on.

Short draws. A 3-year draw gives you less time before principal begins. Some market plans run longer, but the network’s structures are 3 or 5 years.

Title. The lender wants the property held by you personally or by an inter vivos revocable living trust. An LLC, corporation, partnership, or irrevocable, blind, or land trust can’t hold title. That is the sharpest structural difference from a DSCR loan. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead. Whether an LLC borrower is eligible for a DSCR loan depends on lender program requirements.

Property types. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.

Exposure limits. You are limited to three lines. An owner of more than 15 financed properties is not eligible. Combined exposure caps vary by program.

What Happens When the Draw Ends

The draw ends, new borrowing stops, and the amortizing repayment begins. Your balance is the same as it was on the last day of the draw. Now it gets spread over 17 years on the 3-year-draw program or 25 years on the 5-year-draw program, with interest on top.

The step-up is real. Experian says many borrowers see their payment more than double at repayment. Treat that as a market illustration, not a promise for any one plan. Your own step-up depends on how much you drew, how the pricing moved, and how long the repayment runs.

Here is a mini-example in words. Say you carried a flat balance through the entire draw and paid interest only. At the end, the same balance must be repaid over a fixed number of years. The payment now covers the interest and all the principal you never paid. A shorter repayment term makes the step-up bigger.

Three habits soften the landing:

• Pay some principal during the draw. It lowers your balance, so the repayment payment is smaller.
• Plan the last 12 to 24 months. Decide whether you will repay, refinance, or sell. Refinancing needs equity and credit that still qualify when you apply.
• Know the exit. If you refinance, the line must be paid off, and the combined leverage on the property gets tested again.

Paying More Than the Minimum

You can usually pay principal during the draw. On a revolving line, doing so generally restores available credit, so the money isn’t gone. Whether you can redraw depends on the plan.

Paying extra is most useful when your cash flow is strong. It is also your best protection against the repayment step-up. If you make interest-only payments throughout, you reach repayment owing exactly what you drew.

If you miss a required payment, the lender can charge fees and report the delinquency. Because your home secures the line, a prolonged default puts the property at risk. The plan’s contract spells out the exact consequences.

Is Interest-Only a Good Fit for a Rental?

For investors, the low minimum helps during a rehab or while a unit sits vacant. Many investors use equity lines as short-term bridges, then refinance and repeat. Lendmire’s article on interest-only HELOC draws for cash flow landlords goes deeper on that strategy.

Be honest about the limits, though. Equity lines on investment properties are scarce, and the network’s investment ceiling is 70% CLTV with a 700 minimum credit profile, on lines up to $500,000. Because of the 75% draw-at-closing rule, an investment line behaves more like a mostly-funded, interest-only loan than a flexible credit card. It floats, it has a 5-year draw, and it steps up afterward.

A DSCR cash-out refinance is a different tool. Across most of the network, a cash-out on a standard rental tops out around 75% LTV, with about 6 months of seasoning as the common expectation. On short-term-rental collateral, cash-out tops out at 70%. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, and it can be held in an LLC subject to program terms. If your goal is long-term financing of a rental, the DSCR route often fits better. If you want a smaller line against your own equity, the HELOC may work.

One caution on any approach: clearing a DSCR test is not the same as positive cash flow. Repairs, vacancy, management, and utilities sit outside the calculation.

Key Terms Defined

Draw period: the window when you can borrow against the line and the required payment is small.

Repayment period: the phase after the draw ends, when payments cover principal and interest.

CLTV (combined loan-to-value): all loans secured by the property, added together, divided by its value.

DTI (debt-to-income): your monthly debt payments divided by your monthly gross income.

Amortizing: a payment structure in which each payment covers interest plus some principal.

Balloon: a large single payment due at the end of a loan term. An ordinary HELOC repayment phase is not a balloon, but a plan with a lump sum due at maturity is.

Questions to Ask Before You Sign

• How long is the draw period, and how long is repayment?
• Is the minimum payment interest-only, or does it include principal?
• How much must be drawn at closing, and is there a minimum draw afterward?
• Does the pricing float or can I fix it? (On the network’s lines it floats and never converts to fixed.)
• Can I redraw after paying principal?
• What triggers a freeze or reduction of the line?
• Is there a lump sum due at maturity?
