The Quick Read: On a rental property, the draw period is usually interest-only, but the payment steps up when repayment begins, so the line only works if the rental still covers the fully amortizing payment. On Lendmire’s wholesale network, an investment-property line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment, subject to lender guidelines.
- Investment lines cap at 70% CLTV and $500,000 total, with a 700 minimum credit profile.
- At least 75% of the line is drawn at closing, so interest starts on day one.
- Pricing floats through the draw and repayment and never converts to fixed.
- The balance at the end of the draw carries into repayment unchanged unless you pay it down.
- The borrower must hold title personally or in a revocable living trust. An LLC cannot.
Interest-only is the part landlords like and the part that causes trouble. During the draw, the payment covers the cost of borrowing and nothing else. The deal looks healthy. Then the draw ends and the payment changes shape. This article walks through how the line works, how a lender reviews it, where the rules break, and how to decide if it fits.
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.
How Does the Interest-Only Draw Period Work on a Rental?
The draw period is the window when the line is open. You borrow, repay, and borrow again within the limit, and the payment covers interest on the drawn balance. Nothing goes to principal unless you send extra. When the window closes, the line stops revolving and the balance starts amortizing.
The structure on this network for an investment property is fixed. The draw runs 5 years. Repayment then runs 25 years, fully amortizing. Primary residences and second homes can choose a shorter 3-year draw with a 17-year repayment, but that option does not apply to investment lines.
The federal consumer regulator describes the same two-phase design and notes that interest-only is a plan term, not a rule. Some plans build principal into the draw payment. Some end in a balloon. The contract controls, so read it before you assume anything.
One detail changes the “borrow only what you need” idea. On this network, at least 75% of the line is drawn at closing. A $400,000 line is not a dormant standby fund. Most of it is working, and interest accrues from the start. After closing, each later draw has a $1,000 minimum on the longer-runway program (Tennessee is the exception for the shorter terms, and Texas sets a $4,000 minimum).
Here “longer-runway” means the 5-year draw with 25-year repayment structure, the one investment lines use. The other structure, with a 3-year draw and 17-year repayment, is for primary residences and second homes only.
What Happens When the Draw Period Ends?
When the draw ends, the line closes to new borrowing and the payment starts to include principal. The size of the jump depends on three things: the balance you carry, the pricing then in force, and the length of the repayment term. Principal you paid during the draw is the only lever that shrinks it.
Run the logic without dollars. Say a landlord draws most of a line and pays interest only for five years. The balance on the last day of the draw equals the balance on the first day. The 25-year repayment then spreads that full balance across a fully amortizing schedule. A rental that covered the interest-only payment with room to spare can land near break-even or below it on the new payment.
Pricing on this network floats through both phases. It never converts to fixed. So the payment can change even when you draw nothing new, which the consumer regulator also flags for variable-rate plans. That is a second risk, separate from the step-up. Do not stack them without planning for both.
How Do Lenders Review a Rental Property HELOC?
A lender reviews this line on the borrower, not primarily on the rent. That is the sharpest difference from a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC leans on credit, debt-to-income, and equity.
The network figures for an investment line:
| Factor | Investment line |
|---|---|
| Max CLTV | 70% |
| Credit | 700 minimum, 720 and 700 both reach 70% |
| Line size | $25,000 to $500,000 |
| DTI | 50% max; ratio above 45% needs 680+ |
| Valuation | Usually automated, no traditional appraisal |
| Draw / repayment | 5-year / 25-year |
Two points matter on real files.
First, the debt-to-income test uses the interest-only payment calculated on the maximum draw. It does not use the amount you plan to borrow. Size the line to what the DTI can absorb at full draw, not at the draw you intend.
Second, credit above 700 buys no extra leverage on an investment line. Both tiers reach 70% CLTV. The 700 is a hard floor with no tier beneath it. A borrower at 680 is not eligible for an investment line, even though lower scores can work on a primary residence.
Credit history standards also apply. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year seasoning path for a foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale. The credit report can be no more than 90 days old at closing, and rescores are not available.
Because an investment line caps at $500,000, it sits in the automated-valuation lane. Full appraisals begin only above $500,000. A borrower can still ask for one, and a higher CLTV may trigger a secondary valuation. Expect no traditional appraisal in most cases, subject to lender guidelines.
Where the Rule Breaks: Edge Cases That Derail Files
The general rule is simple: personal borrower, 70% CLTV, interest-only for five years. Several named cases break it.
Vesting in an LLC. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. Title must sit with the individual or an inter vivos revocable living trust. A property already deeded to an LLC needs a vesting change first, or the better path is a DSCR cash-out refinance. This is the most common file-killer for landlords who structured for liability protection.
Property type. Single-family, 2-4 units, PUD, townhome, and condominium (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
Exposure limits. A borrower is limited to three lines. A borrower owning more than 15 financed properties is not eligible. Portfolio landlords hit this ceiling sooner than they expect.
Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
Texas non-homestead. Texas investment properties are treated as non-homestead transactions, so the primary-residence waiting period and one-lien rule do not bind them. Texas properties are limited to 10 acres.
Availability. These lines are brokered only in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the 41-market DSCR footprint.
Market scarcity. Rental-secured lines are harder to find than home lines. One investor thread on BiggerPockets describes hunting through banks and credit unions for a lender willing to write one, and that matches what brokers see on the ground. Market-wide, reported leverage on rental lines varies by lender. On this network the investment ceiling is 70% CLTV, full stop.
Key Terms Defined
Draw period: The window when you can borrow, repay, and borrow again within the line’s limit.
Repayment period: The phase after the draw, when the line stops revolving and payments include principal.
Interest-only payment: A payment that covers the cost of borrowing on the drawn balance and does not reduce principal.
CLTV: Combined loan-to-value, which adds every lien on the property and compares the total to its value.
PITIA: Principal, interest, taxes, insurance, and any association dues. DSCR compares rent to this number.
DSCR: Debt service coverage ratio, meaning monthly rent divided by PITIA on the loan being reviewed.
Does Rent Cover the Payment After the Draw Ends?
Rent has to cover two things at once: the first mortgage and the amortized HELOC. That is the test that matters, and the interest-only period hides it.
Run the numbers this way. Picture a landlord with a rental whose rent covers the first mortgage at a healthy margin. Add the interest-only line payment and the margin narrows but holds. Now switch the line to a fully amortizing payment. The cushion that existed during the draw can disappear. A deal that cash-flows on interest only may not cash-flow on a fully amortizing payment.
One caution on language. A coverage ratio above 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside that calculation, so a line that “clears” on paper can still bleed in practice.
An investor on BiggerPockets warns that negative carry on floating debt is precarious and calls for sizeable reserves. That is practical advice. Stress three cases before you sign: a vacancy stretch, a payment rise from floating pricing, and the full amortizing payment at the balance you expect to carry.
Draw discipline helps. Voluntary principal payments during the interest-only phase shrink the later step-up. They also restore availability on the line. Keep draws segregated by purpose so you can trace what each one funded.
HELOC or DSCR Cash-Out: How the Two Compare
A HELOC suits a short, defined purpose with a clear takeout. A DSCR cash-out refinance suits permanent debt on a held rental. The two use different underwriting, and a landlord choosing between them is really choosing between borrower-based and property-based review.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Underwritten on | Borrower credit and DTI | Property rent vs. payment |
| Leverage | 70% CLTV on investment | Up to 75% LTV on a standard rental |
| Entity ownership | Individual or revocable trust only | LLC possible, subject to lender program eligibility |
| Structure | 5-year draw, 25-year repayment | 30-year fixed spine; interest-only periods and extended terms through select lenders |
| Size | Up to $500,000 | Up to $3,000,000 on standard programs |
| Seasoning | Per line terms | About 6 months is the common expectation |
Short-term-rental collateral follows tighter leverage on a cash-out, at 70%, while a standard rental tops out near 75%.
The complete DSCR loans guide covers how the property-based path is reviewed in full.
What Is the Exit Before the Draw Ends?
The exit has to exist before the draw closes. Investor threads converge on the same three: refinance, sell, or pay down from cash flow. A balloon or a step-up is manageable only if one of those is ready.
Build a decision timeline for the final year of the draw:
1. Check the balance you will carry and the fully amortizing payment it produces.
2. Compare that payment to rent after vacancy and operating costs, not just against the first mortgage.
3. Price a refinance into a long-term structure, such as a DSCR cash-out, and confirm the property and borrower still meet the standards.
4. Decide whether a partial paydown from cash flow closes the gap.
5. If none of those work, plan a sale while you still have time.
On a DSCR refinance, 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. Typical files carry about 6 months of PITIA in reserves, though that varies by lender, leverage, and loan size.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Who Should Use an Interest-Only Rental HELOC?
Use it for a bridge. A down payment on the next purchase, a rehab with a refinance planned behind it, or a reserve cushion with a defined payoff all fit. The buy, rehab, lease, refinance, and repeat sequence is the classic use, and it works when the takeout is real.
Skip it as permanent debt on a thin deal. Floating pricing, a stepped-up payment, and a collateral lien on the rental make it a poor fit for a property that barely covers its costs. Another landlord option is a line on a primary residence, which puts the home at risk instead of the rental. Neither is free of exposure.

Frequently Asked Questions
Can I choose an interest-only draw on a rental line?
On this network the investment structure is fixed at a 5-year interest-only draw with a 25-year fully amortizing repayment, so there is no choice to make. Plans elsewhere in the market vary, and the consumer regulator notes that some require principal during the draw.
Do I pay interest on the whole limit or only what I draw?
Interest accrues on the drawn balance. The catch is that at least 75% of the line is drawn at closing on this network, so most of the limit is working from day one. Later draws carry a $1,000 minimum, subject to the program terms.
Can an LLC borrow against a rental?
No. Title must sit with the individual or a revocable living trust. A property already in an LLC needs a vesting change, or a DSCR cash-out may fit better, subject to program terms.
Does rent count in qualifying?
Not primarily. The line is reviewed on credit, debt-to-income at the maximum draw, and equity, up to a 50% DTI. A DSCR loan reviews the property’s rent against its payment instead.
What if I cannot refinance when the draw ends?
Then the full balance amortizes over the 25-year repayment, and floating pricing means the payment can still move. Pay principal down during the draw, hold reserves, and test the post-draw payment against rent before you take the line.
Can I pay principal during the draw?
Yes. Voluntary principal payments shrink the balance that carries into repayment and restore availability on the line. They are the only lever that reduces the later step-up.
