The Quick Read: A home equity line with an interest-only draw period lets you borrow against your equity and pay only the interest on what you have drawn for a set number of years, and on the wholesale network Lendmire works with, that draw runs 3 or 5 years before full principal-and-interest payments begin. Which lender fits depends on your property type, credit profile, and how much combined leverage you need. Lendmire is a broker, not a lender, so it matches your file to a program that fits.
- Investment-property lines use a 5-year interest-only draw and a 25-year repayment, with a 700 minimum credit score, a 70% combined loan-to-value (CLTV) ceiling, and a $500,000 maximum line.
- Primary-residence and second-home lines offer two structures: a 3-year draw with a 17-year repayment, or a 5-year draw with a 25-year repayment.
- At least 75% of the line is drawn at closing, and pricing floats through both the draw and the repayment.
- Title must sit with an individual or a revocable living trust, so an LLC-owned rental cannot hold one of these lines.
What Does an Interest-Only Draw Period Actually Mean?
Interest-only is a payment feature of the draw phase. It is not a separate product. During the draw, you can borrow up to your limit, repay, and borrow again, and you owe interest on the balance you are carrying. Your principal does not shrink unless you pay extra.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Not every line works this way. The federal consumer-finance regulator says many lines base the minimum payment on your current balance, and it does not say all of them are interest-only. Some market lines require a slice of principal in the minimum. Others end the draw with a balloon, meaning the whole balance comes due at once.
How long does the draw last? Experian puts the typical draw at five to ten years, followed by a 20-year repayment. Bankrate says draws typically run up to 10 years. Those are market-wide ranges. The network Lendmire places files with is narrower: 3-year and 5-year draws, and both fully amortize afterward, with no balloon.
Key Terms Defined
Draw period: the stretch when you can borrow from the line and, on interest-only structures, pay interest only on the drawn balance.
Repayment period: the stretch after the draw closes, when you can no longer borrow and the balance is paid down.
Fully amortizing: each payment includes both interest and principal, so the balance reaches zero by the end of the term.
CLTV (combined loan-to-value): all loans against the property, including the new line, divided by the property’s value.
DTI (debt-to-income): your monthly debts divided by your monthly income.
Lien position: whether the line sits first in line to be repaid (first lien) or behind an existing mortgage (second lien).
Balloon: a lump sum due all at once when a term ends.
How Do Lenders Underwrite an Interest-Only Line?
Lenders underwrite the line against you, not against the rent. The review runs in a set order, and the strictest step is usually the payment test. Here is how it works across the wholesale network.
1. Credit. The lender pulls a single-bureau score keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not allowed. The minimum score depends on occupancy: 600 on a primary residence, 640 on a second home, and 700 on an investment property.
2. Equity. The lender adds the existing mortgage balance and the new line, then divides by the property’s value. That is your CLTV, and the ceiling depends on credit tier and occupancy.
3. Valuation. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal, though a higher CLTV may require a second valuation. Anything above $500,000 needs a full appraisal. You can also request one on any line.
4. Payment test. DTI is qualified on the interest-only payment calculated on the maximum draw, not on what you have drawn. A half-used line is tested as if it were fully used.
5. DTI limits. The maximum is 50%. Profiles from 600 to 679 are capped at 45%, and anything above 45% needs a 680 minimum.
6. History. Tradeline and housing-history standards vary by program, and they apply across all financed properties. A bankruptcy needs four years of seasoning from discharge or dismissal.
7. Exposure. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible.
Step four is where investors get surprised. The payment test uses the full line, so a large limit can strain your DTI even if you plan to draw little.
NerdWallet notes that rental-property lines come from a smaller pool of lenders. It also reports market surveys showing a typical 720 credit score and an 80% loan-to-value ceiling on investment-property lines. On the network Lendmire works with, an investment-property line caps at 70% CLTV with a 700 minimum score. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
What Do the Network’s Programs Look Like?
The ceilings and credit minimums depend on occupancy, and the investment tier is the tightest. Here is the occupancy-level view.
| Occupancy | Minimum credit | Top CLTV | Maximum line |
|---|---|---|---|
| Primary residence | 600 | 90% (720+, to $500,000) | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 640 | 90% (720+, to $500,000) | $500,000 |
| Investment property | 700 | 70% | $500,000 |
Below the top tier, primary-residence leverage steps down with credit. A 700+ profile reaches 85% CLTV up to $500,000, and a 620+ profile reaches 70% up to $400,000. Second homes step down in a similar way.
Lines above $500,000 are primary-residence only. They require a 700 credit profile or better (720 on the longer-runway 5-year program), cap at 75% CLTV, and need a full appraisal.
Two draw structures exist on primary residences and second homes:
| Feature | 3-year program | 5-year program |
|---|---|---|
| Interest-only draw | 3 years | 5 years |
| Repayment | 17 years | 25 years |
| Investment lines | Not offered | Offered |
On both, at least 75% of the line is drawn at closing. Later draws carry a $1,000 minimum, and one state in the footprint sets a higher floor. Because pricing floats through both phases, the interest-only payment moves with the market index. It does not stay flat for five years.
Eligible property types include single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos. Modular factory-built homes are eligible on the 5-year program only. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Availability is limited to Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That footprint is narrower than the DSCR loan footprint.
What Happens When the Draw Ends?
When the draw ends, you can no longer borrow, and your payment resets to cover principal as well as interest. The CFPB says repayment is often scheduled over ten or 20 years and the monthly payments are often significantly higher. In some cases, it adds, you may have to repay the whole amount as soon as repayment begins.
Run the mechanics without dollars. In month 61, the same balance must amortize over the 300-month repayment. Five years of untouched principal now gets repaid in 25 years, so the payment steps up.
On the 3-year program, the reset comes after 36 months and the principal is spread over 204. The step-up therefore arrives sooner, and the balance is repaid over a shorter stretch than on the 5-year structure.
| Item | Draw period | Repayment period |
|---|---|---|
| Borrowing | Allowed, up to the limit | Closed |
| Payment | Interest on drawn balance | Principal plus interest |
| Principal | Falls only if you pay extra | Falls with each payment |
| Pricing on this network | Floats | Floats |
Paying principal voluntarily during the draw is allowed and shrinks the jump. The smart approach is to treat the interest-only period as a floor, not a target.
Where Does the General Rule Break?
The rule of thumb is that a HELOC suits owner-occupied homes and rentals are harder. Several edge cases bend that rule.
An LLC cannot hold the line. Title must be held by the individual borrower or an inter vivos revocable living trust, which is a trust you can change during your lifetime. 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 instead, subject to program terms.
Occupancy changes the whole file. An investment line has a higher credit floor, a single draw structure, and a 70% CLTV ceiling. The same property as a primary residence or second home qualifies under looser tiers. State the occupancy honestly, because the lender will verify it.
A line on your own home can fund a rental. Many investors pull equity from the home they live in, then use it for a down payment. That moves the collateral and the occupancy tier back to the primary residence.
Listed properties can be ineligible. In several of the 16 states, a property listed for sale, or listed within the past 60 days, is ineligible.
Derogatory history splits by program. One program seasons a foreclosure for 7 years and a deed-in-lieu, pre-foreclosure, or short sale for 4. The other declines that history entirely, regardless of age.
Some states shorten the terms. One state in the footprint cuts the 3-year structure to a 12-year repayment and the 5-year structure to a 10-year repayment.
First-lien lines exist. The network offers standalone lines in first or second lien position. A line does not have to sit behind your existing mortgage.
HELOC or DSCR Cash-Out?
A line is reviewed on your personal credit and DTI. A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. That difference decides which product fits.
DSCR means debt service coverage ratio: the monthly rent divided by the monthly payment, including principal, interest, taxes, insurance, and any HOA dues. Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
A pure rental purchase or a portfolio built on many entities can collide with the HELOC limits above: the $500,000 investment cap, the 70% CLTV ceiling, the three-line limit, and the LLC title rule. Those are the cases where DSCR financing may be the practical fit. The complete DSCR loans guide covers the full picture, and Lendmire arranges DSCR investor loans across 40 states plus Washington, D.C.
Typical DSCR numbers on the network look different:
- A cash-out refinance on a standard rental typically tops out around 75% LTV, with about 6 months of seasoning commonly expected.
- Coverage of 1.00 is where select programs start. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted.
- Credit floors start at 620 in parts of the network. Most programs want around 660, and 700+ opens the strongest leverage tiers.
- Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), and a 30-year fixed is the spine of the lineup.
- Extended 40-year terms and interest-only periods are available through select lenders in the network.
- Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA, which is principal, interest, taxes, insurance, and association dues.
Equity and rental coverage are separate tests, and the strongest files clear both. A bigger down payment can lift coverage, but it never erases leverage caps, credit floors, or property eligibility. For investors weighing a line against an interest-only DSCR structure, Lendmire’s piece Top HELOC Providers With Interest-Only Payments During the Draw Period shows the HELOC side in more depth.
Who Fits and Who Should Skip?
An interest-only line fits an investor who has a defined exit before the first draw. It can carry a rehab or a down payment while the property stabilizes. It suits someone whose rental cash flow already covers the interest-only payment with room to spare, and who plans to pay most of the balance down before the draw ends.
It also fits borrowers with strong personal credit and low DTI who own the property in their own name or a revocable trust.
Skip it if any of these describe you:
- Your plan only works while the payment stays interest-only.
- You hold the rental in an LLC and do not want to retitle it.
- You need more than $500,000 against an investment property.
- You are near the 50% DTI ceiling, because the test uses the full line.
- You expect to run past three lines or 15 financed properties.
Interest-only also carries a quiet risk. The payment floats with the index, and it never retires the debt. Lenders generally can freeze or reduce a line under certain conditions, so confirm those terms in the line agreement before you rely on future draws.
How Do You Compare Lenders Without Comparing Rates?
The right lender depends on the file, not on a ranking. A broker that shops multiple wholesale lenders can match your property, occupancy, credit profile, and leverage need to a program that fits. Before you apply, get these answers in writing:
1. Is interest-only required during the draw, or just allowed?
2. What is the draw length, and what is the repayment length after it?
3. Does the line ever convert to fixed pricing, or float throughout?
4. What are the minimum initial and subsequent draws?
5. Is the payment qualified on the maximum draw or the drawn balance?
6. Which valuation is required at your line size?
7. How does the lender treat your occupancy, vesting, and property type?
8. Under what conditions can the line be frozen or reduced?
Then build the exit plan before the first draw. Decide whether you will pay down principal during the draw, refinance into a DSCR loan, or sell. Write that plan down before the first draw, because the structure rewards the investor who has one.

Frequently Asked Questions
Is every HELOC interest-only during the draw?
No. Many lines base the minimum payment on the balance, but some require a slice of principal, and some end the draw with a balloon. The network’s lines are interest-only during the draw and fully amortizing afterward. Confirm which payment feature your line carries.
Can I pay down principal during the draw period?
Yes, voluntary principal payments are generally allowed, and they shrink the payment jump when repayment begins. On the 5-year program that is 60 months of borrowing room. Paying extra turns a floating interest-only payment into a shrinking balance.
Can I extend or renew the interest-only period?
Within the network’s structures, the draw length is fixed by the program you choose, 3 years or 5. When the draw ends, repayment begins. Investors who need more runway usually plan a payoff or a refinance before the end of the draw.
Can a line be placed on a rental I own in an LLC?
Not directly. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. A property already in an LLC needs a vesting change, or a DSCR cash-out refinance instead, subject to program terms.
How big can an investment-property line be?
An investment-property line is capped at $500,000 and 70% CLTV, with a 700 minimum credit score and the 5-year draw structure only. Lines above $500,000 are limited to primary residences.
