Interest-Only HELOC Draw Requirements for a Primary Home

The Quick Read: On a primary home, an interest-only line through Lendmire’s wholesale network requires you to draw at least 75% of the line at closing. You then pay only interest during a 3-year or 5-year draw period, followed by fully amortizing repayment over 17 or 25 years. Lenders test your qualification on the interest-only payment at the maximum draw, not on the amount you plan to use.

• Draw structure: a 3-year interest-only draw with 17-year repayment, or a 5-year draw with 25-year repayment, subject to lender guidelines.
• Initial draw: at least 75% of the line is drawn at closing on both programs.
• Later draws: the 5-year program sets a $1,000 minimum per draw after closing.
• Credit and leverage: the credit floor is 600, and 90% CLTV exists only at 720 or better, subject to lender guidelines and full file review.
• Debt-to-income: 50% maximum, with tighter limits below a 680 score.

Most people hear interest-only and picture a flexible credit card. It is closer to a term loan with a long interest-only runway. The payment looks small for a few years and then steps up.

What Does Interest-Only Mean on a HELOC?

A home equity line of credit (HELOC) is a revolving line secured by your home. During the draw period, the required payment covers interest on the balance you have drawn. It does not cover principal. When the draw period ends, you repay principal plus interest.

Market-wide, consumer-finance publishers commonly describe a draw period of about 10 years. Experian says it usually lasts 10 years and that you pay only interest during it. Bankrate says it typically runs up to 10 years. The network’s primary-residence programs are shorter: 3 or 5 years, followed by a fixed repayment window.

Interest-only does not mean you owe less. Principal is deferred, not forgiven. The balance you carry out of the draw period is the balance you repay.

How Much Must You Draw at Closing?

At least 75% of the line is drawn at closing on both programs we place files with. This is the requirement most explainers skip.

It changes the usual advice that you only pay on what you use. That advice holds for lines with no minimum initial draw. Here, most of the line starts as a drawn balance, and interest accrues on it from day one. Pricing also floats through both the draw and repayment periods. It never converts to fixed. When pricing floats, the payment can change even if you draw nothing more.

After closing, the 5-year program sets a $1,000 minimum for each subsequent draw. The 3-year program does not state a subsequent-draw minimum. A small number of states raise the subsequent-draw minimum, so confirm the figure for your property.

In practice, size the line to the money you actually need. A larger line does not cost you less when 75% of it is drawn on day one.

How Underwriting Treats the Draw, Step by Step

Here is the order a lender works through on a primary-home line.

1. Credit pull. The score comes from a single-bureau model keyed to the primary wage earner. The report must be no more than 90 days old at closing, and there are no rescores. The floor is 600.

2. Tradelines and housing history. The 5-year program wants two tradelines seasoned 12 months, or one seasoned 24. Housing history must be 0x30x6 and 1x30x12 at 640 and above, or 0x30x12 from 600 to 639. This applies across all financed properties.

3. Debt-to-income (DTI). DTI is your monthly debts divided by your monthly income. The maximum is 50%. It is 45% for scores from 600 to 679, and anything above 45% needs a 680 minimum.

4. The payment tested. The lender reviews your file on the interest-only payment calculated on the maximum draw. A smaller planned balance does not lower the hurdle.

5. Valuation. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation. Every line above $500,000 needs a full appraisal, and you may request one in any case.

6. Title. Title must be held by you individually or by your inter vivos revocable living trust.

Some lenders in the network add overlays beyond this list. Subject to lender guidelines, every file gets a full review.

Credit Tiers and Combined Leverage

Combined loan-to-value (CLTV) adds your first mortgage and the new line together, then divides by the home’s value. Here is how the ceilings stack on a primary residence.

These are primary-residence ceilings for a standalone line in first or second lien position, subject to lender guidelines. The top tier is not generally available. The 90% figure exists only at 720 or better, and it tops out at a $500,000 line.

At 720, you face a tradeoff. You can take 90% CLTV up to $500,000, or a larger line up to $750,000 at a reduced 75%. A line above $500,000 is primary-residence only. It needs a 700 credit profile or better (720 on the 5-year program), a 75% CLTV cap and a full appraisal.

Investment-property lines are a different product. On an investment line the ceiling is 70% CLTV, with no tier above it.

Two Draw Structures

A figure quoted to you always carries its own program’s draw and repayment structure. Compare the two on the same line size before you choose. The shorter draw means principal payments begin sooner, while the longer one stretches repayment and gives the line more runway.

What Happens When the Draw Period Ends

The line closes to new advances, and payments shift to principal plus interest. Nothing in your borrowing history changes. The structure does.

The CFPB’s HELOC explainer describes the draw period as the stretch when you can borrow up to the limit. The CFPB consumer booklet adds that some plans allow interest-only payments, while others fold some principal into the minimum. It also notes that a repayment period follows either way. Some plans end in a balloon payment, where the whole balance comes due at once. The network’s primary-residence programs amortize fully, so no balloon applies.

The step-up depends on three things: the balance you carry in, the pricing at that time, and the repayment term. We do not quote a dollar jump here because it varies too much by file. Run the calculation on your own balance before you sign.

If the draw funded a down payment, the step-up arrives while the loan on the property you bought is already running its own payment. Both land on you at once. Plan a payoff route in advance: refinance, sale, or voluntary principal payments during the draw period.

Where the General Rule Breaks

The basic rule is a primary home, an individual borrower and a clean credit profile. These cases are the named exceptions.

• Business bank accounts. Using them for the deposit analysis requires a 680 minimum. The primary-residence floor is 600, so a 640 borrower qualifies for the line but cannot use business accounts.
• LLC-owned property. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead. This is the sharpest structural difference from a DSCR loan.
• Lower credit profiles. Under the 5-year program, profiles below 640 are limited to single-family residences with a clean 12-month housing history.
• Past derogatory events. A bankruptcy needs 4 years of seasoning from discharge or dismissal on both programs. A foreclosure splits. One program seasons it for 7 years, and a deed-in-lieu, pre-foreclosure or short sale for 4. The other declines the history entirely, regardless of age.
• Property type. Single-family, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable condominiums, are eligible. 2-4 unit properties need a 640 minimum on the 5-year program. Modular factory-built homes are eligible on the 5-year program only. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use or agricultural-zoned properties are not offered.
• Recent listings. A property listed for sale, or listed within the past 60 days, is ineligible in several states.
• Exposure caps. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the 3-year program and $750,000 on the 5-year program. Owning more than 15 financed properties makes you ineligible.

Availability is narrower than you might expect. These lines are offered only in Lendmire’s 16 full-service states, not the full DSCR footprint of 41 markets, including Washington, D.C.

Should You Use a Primary-Home Line to Buy a Rental?

It depends on whether you can carry two debts at once. A HELOC on your primary home is secured by that home. If the rental underperforms and the draw goes unpaid, your primary residence is the collateral. That is a different risk from a loan secured only by the rental.

Many investors use a line like this to fund a down payment. The rental purchase itself usually runs on a DSCR loan. DSCR stands for debt service coverage ratio, which compares a property’s monthly rent to its monthly PITIA (principal, interest, taxes, insurance and association dues). The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.

Across our wholesale network, most DSCR purchase files land at 75%-80% LTV, or 20%-25% down. Select programs reach 85% LTV (15% down) with roughly a 700+ score. Coverage of 1.00 is where many 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. Reserves commonly run around 6 months of PITIA, but they vary by lender, leverage, loan size and transaction type.

Two cautions apply.

• The DSCR ratio is not a cash-flow number. It compares rent to PITIA only. Repairs, vacancy, management, utilities and capital expenses sit outside it. Clearing 1.00 does not mean the rental pays for itself or covers your line payment.
• Where the down payment came from matters. How a lender treats borrowed funds, source-of-funds documentation and reserves varies by program. The HELOC lender separately checks your DTI and credit. Confirm both before you commit.

If you already own a rental with equity, a DSCR cash-out refinance is the usual alternative. It tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. See the complete DSCR loans guide for how the rental side works. For the cash-flow side of a draw period, Lendmire’s piece Rental Property HELOC Interest Only Draw Period for Cash Flow Landlords goes further. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

This is a genuine toss-up for first-time investors. The line makes the down payment possible, but it ties your home to the investment. A buyer with solid reserves and a payoff plan sleeps fine. A buyer counting on rent to cover everything often does not.

Key Terms Defined

Draw period: the stretch when you can borrow from the line. Here it lasts 3 or 5 years.

Repayment period: the stretch after the draw ends when you repay principal and interest. Here it lasts 17 or 25 years.

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

DTI (debt-to-income): your monthly debt payments as a share of your monthly income.

DSCR: a rental property’s income divided by its monthly PITIA.

Balloon payment: a single large payment due when a loan ends, instead of gradual repayment.

Next Step

If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. The line gives you a down payment, but the rental still has to hold up once both debts are running.
