The Quick Read: The best program for a given investor is the one whose draw structure, title rules, and review basis match the borrower and the property, because an interest-only period lowers the required payment during the draw but does not pay down the balance. Across Lendmire’s wholesale network, the investment-property line carries a 5-year interest-only draw followed by a 25-year fully amortizing repayment. That is the only draw structure offered on investment collateral, and every figure below is subject to lender guidelines.
- The investment-property line reaches 70% CLTV, requires a 700 minimum credit score, and tops out at $500,000.
- At least 75% of the line is drawn at closing, so interest accrues on most of it from day one.
- Title must sit with an individual or a revocable living trust. An LLC cannot hold title.
- Pricing floats through the draw and the repayment period and never converts to fixed.
- Interest-only improves monthly cash flow only until year five, when principal enters the payment.
Which program is best depends on who is asking, and a broker answers that differently from a single bank. Lendmire is a mortgage broker, not a lender. It shops wholesale HELOC lenders and matches the scenario to the program, so the program that fits one investor can be the wrong one for the next. The sections below explain how the line works, how it is qualified, where it breaks, and when a DSCR cash-out refinance is the better tool.
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.
What an Interest-Only Investment HELOC Actually Is
An investment HELOC is a revolving line secured by a rental property. During the draw period the required payment covers only the interest on what has been borrowed. Once the draw period ends, borrowing stops and the payment resets to include principal.
The line is a standalone product. It can sit in first-lien position on a rental with no mortgage, or in second-lien position behind an existing first mortgage. The second-lien case matters because it leaves a good first mortgage untouched. A cash-out refinance replaces that loan.
Interest-only is a common pattern, not a universal feature. Experian describes a typical draw period of about 10 years, with only interest owed on the borrowed amount, followed by a repayment phase with no further draws. The plan contract decides, and some plans fold principal into the minimum payment from the start. That is a market-wide description. The network’s investment line uses a 5-year draw, not 10. Lendmire’s piece on a 10-year interest-only draw period covers the longer-draw question separately.
Key Terms Defined
Draw period: the window when you can borrow against the line and owe only interest on the drawn balance.
Repayment period: the phase after the draw ends, when borrowing stops and each payment includes principal and interest.
CLTV: combined loan-to-value, which adds the first mortgage and the line together and measures them against appraised value.
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly housing obligation.
DSCR: debt service coverage ratio, which divides monthly rent by the monthly PITIA on the loan.
Initial draw: the amount funded at closing. On the network’s investment line, at least 75% of the line.
What Makes a Program the Best Fit for an Investor?
Fit comes down to six features: draw length, repayment length, leverage, title, pricing behavior, and review basis. No single program wins on all six for every borrower.
| Feature | Network investment line |
|---|---|
| Draw / repayment | 5-year interest-only / 25-year amortizing |
| Max leverage | 70% CLTV |
| Minimum credit | 700 |
| Line size | Up to $500,000 |
| Title | Individual or revocable living trust |
| Pricing | Floats; never converts to fixed |
Credit above 700 buys eligibility, not leverage. Both the 720-plus and 700-plus tiers reach the same 70% CLTV on an investment property. Below 700, the investment line is not available at all.
Run the choice through your situation. An investor who owns the rental personally, holds a good first mortgage, and wants a modest amount of equity in a form that keeps the first loan intact is the natural fit. An investor with the property in an LLC, a first mortgage worth replacing, or a need for more than $500,000 is not.
How Underwriting Treats the Line, Step by Step
On this product, the borrower is the underwriting subject, not the rent roll. Here is the sequence a file moves through.
1. Eligibility screen. The property must be a single-family home, a 2-4 unit, a PUD, a townhome, or a condominium, including a non-warrantable condo. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered. A borrower with more than 15 financed properties is not eligible.
2. Credit. The minimum score is 700 on an investment line. The report cannot be more than 90 days old at closing, and the program does not rescore.
3. Equity and CLTV. The first mortgage plus the full line must stay at or below 70% of value. This is the test that thin-equity rentals fail.
4. Valuation. Because an investment line caps at $500,000 and full appraisals start only above that size, the file runs on automated valuation and commonly closes without a traditional appraisal. A borrower may still request a full appraisal.
5. DTI. Debt-to-income is capped at 50%. It is tested on the interest-only payment calculated on the maximum draw, not on the amount you plan to borrow. A small planned draw does not shrink the qualifying payment.
6. Title and vesting. The deed must name the individual borrower or an inter vivos revocable living trust.
7. Closing draw. At least 75% of the line funds at closing.
This is a different test from a DSCR loan. A HELOC looks at you. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Rent matters far less on the line.
The 75% Draw Rule Changes the Cash-Flow Picture
Many investors picture a HELOC as a flexible card they draw on when needed. The network’s investment line does not work that way. With at least 75% drawn at closing, it behaves like a mostly funded interest-only loan with a small revolving sliver.
Interest accrues on the drawn balance from day one. The minimum payment equals that accrued interest, so it rises as you draw more. The CFPB’s overview of how a HELOC works notes that some plans require an initial draw when the line opens and that these lines usually carry variable pricing. The network’s 75% rule is a stricter version of that initial-draw feature.
After closing, later draws are allowed within the line. Where a program states a minimum subsequent draw, it is $1,000, with Texas at $4,000. Pricing floats through both the draw and the repayment period, so the interest-only payment can move.
What Happens When the Draw Period Ends
The step-up arrives at year five. On the network’s investment line, the balance carried on the last day of the draw is amortized over 25 years. Five interest-only years leave principal untouched, so the repayment-phase payment is built on the full outstanding balance.
Consider an illustration with modeled inputs, not market facts. Suppose a rental covers its full monthly obligation at roughly 1.4x while only interest is due. When principal joins the payment, that ratio can slide toward 1.0x or below on the same rent. Stress-test the rental against the post-draw payment before borrowing, not after.
A short checklist helps:
- Model the payment at the maximum draw, since that is what DTI uses.
- Model the payment after year five, with principal included.
- Test both against realistic rent, not the highest rent the unit has ever achieved.
- Plan the exit: a sale, a refinance, or a paydown from reserves.
The CFPB’s HELOC booklet adds one more rule to plan around. If you sell the property, you generally must pay off the line in full.
Interest-Only Helps Cash Flow, Not DSCR
An interest-only draw lowers the required payment, and that is the entire cash-flow benefit. It does not make the loan cheaper. The balance stays level, and principal is deferred rather than avoided.
The two measures also get confused. DSCR compares rent to PITIA only. Clearing 1.00 on that ratio is not the same as positive cash flow, because repairs, vacancy, management, utilities, and capex all sit outside the calculation.
The same logic applies to the line. A lower interest-only payment improves the monthly number, but it does not change the property’s underlying economics. The complete DSCR loans guide walks through how coverage is calculated if you want the full mechanics.
Where the General Rule Breaks
The edge cases are where files get stuck. Most of them involve title, leverage, or availability.
LLC-titled rentals. The network’s line cannot be written to an LLC, a corporation, a partnership, or an irrevocable, blind, or land trust. A property already deeded to an LLC needs a vesting change or a different product. A BiggerPockets thread on HELOCs for properties held in an LLC shows the same wall at the broader bank level: commenters describe most banks preferring personal-name title. Some commenters mention temporarily moving title, which can create its own lender and insurance problems and is not something to do without advice.
Texas and listing status. Texas investment properties are eligible as non-homestead transactions, and Texas properties are limited to 10 acres. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
Exposure limits. A borrower is limited to three lines in total. Combined exposure caps at $2,000,000 on the network’s higher-leverage program and $750,000 on its longer-runway program. An investment line itself tops out at $500,000, so a portfolio investor can hit the ceiling before the equity runs out.
Geography. The line is available 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, which covers 40 states plus Washington, D.C.
Thin bank availability. Many conventional banks decline non-owner-occupied lines or restrict them heavily. A BiggerPockets discussion of HELOCs for investment property describes investors making repeated calls to find a desk willing to write one. That is anecdotal, and no national count of banks offering rental lines exists. A broker that shops several wholesale lenders reduces that search, but it does not change the product limits above.
Seasoning. Neither a line nor a cash-out refinance is typically available on a rental owned under about six months. Seasoning on cash-out files varies by lender.
HELOC vs. DSCR Cash-Out Refinance
These two products solve different problems. The comparison turns on size, title, and what is being qualified.
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| Reviewed on | Borrower credit, DTI, equity | Property rent vs. PITIA |
| Max leverage | 70% CLTV | About 75% LTV, standard rentals |
| Size | Up to $500,000 | Up to $3,000,000 on standard programs |
| LLC title | Not allowed | Subject to lender program eligibility |
| First mortgage | Stays in place | Replaced |
A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It tops out around 75% LTV across most of the network and commonly expects about six months of seasoning. A coverage of 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Interest-only periods and extended 40-year terms are also available through select lenders in the network, which gives a DSCR borrower a similar cash-flow lever on a larger loan.
The DSCR route fits when the property sits in an LLC, when the first mortgage is worth replacing, or when the equity need exceeds the HELOC’s $500,000 cap. The line fits when the first mortgage is worth keeping and the borrower holds title personally.
Stacking and Pricing Risk
A second lien reduces remaining equity. Before borrowing twice against the same rental, add the first mortgage and the full line together and confirm the combined figure sits at or under the 70% ceiling. The test uses the full line, not the drawn amount.
Floating pricing is the other exposure. Because pricing never converts to fixed, the interest-only payment that looked comfortable at closing can move through the draw. Build a margin into the cash-flow model rather than assuming the opening payment holds for five years.
Balance creep is the third risk. With a revolving feature and a minimum payment that equals only interest, the temptation is to draw again. Each draw raises the next qualifying payment and shrinks the equity cushion.
What Lenders Look For and What to Prepare
Fit starts with a clean title and a clean credit file. Have these ready before the file goes in:
- Deed showing vesting in your personal name or revocable living trust
- Current mortgage statement if a first lien exists
- Credit report within the 90-day window at closing
- Debt schedule to support the DTI calculation, tested at the maximum draw
- A clear plan for the year-five step-up
Credit history standards vary by program. One wholesale program wants two tradelines seasoned 12 months or one seasoned 24. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history on an investment file follows a 7-year path for a foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale.
Frequently Asked Questions
Is every investment property HELOC interest-only during the draw?
No. Many plans are, but some build principal into the minimum payment from the start, as the CFPB’s HELOC booklet notes. The plan contract decides. On the network’s investment line, the draw is interest-only for five years, then amortizes over 25.
Can an LLC borrow on this line?
No. The line requires title in an individual’s name or an inter vivos revocable living trust. An LLC-held rental needs a vesting change first, or a DSCR cash-out refinance instead, subject to lender program eligibility.
How much can I borrow, and at what leverage?
Up to $500,000 on an investment property, at up to 70% CLTV, with a 700 minimum credit score. Credit above 700 does not raise the ceiling. Terms are subject to lender guidelines and full file review.
Does the interest-only period raise my DSCR?
It does not apply directly, because this line is qualified on the borrower, not the rent. DTI is tested on the interest-only payment at the maximum draw. For a DSCR loan, coverage compares rent to the full PITIA, and an interest-only structure through a select lender can lift that ratio during the interest-only period.
What happens at the end of the draw period?
Borrowing stops and the balance amortizes over 25 years on the network’s investment line. Because no principal was repaid during the draw, the payment resets to include principal on the full balance. Test your rent against that payment before you borrow.
