The Quick Read: A flexible HELOC repayment structure pays interest only while you draw, then moves to fully amortizing payments on a fixed schedule. The best provider for you depends on your occupancy type, credit profile, and how much of the line you need at closing, not on a single ranking. Lendmire is a mortgage broker that shops a network of wholesale HELOC lenders and matches the file to the program that fits.
- Two draw structures exist on primary residences and second homes: a 3-year interest-only draw with a 17-year repayment, and a 5-year draw with a 25-year repayment.
- Investment-property lines use the 5-year draw and 25-year repayment structure only, and the ceiling there is 70% CLTV.
- Pricing on these lines floats through both the draw and the repayment period and never converts to fixed.
- Qualification tests the borrower’s credit and debt-to-income ratio, not the rent the property produces.
- Availability is limited to Lendmire’s 16 full-service states, which is narrower than its DSCR footprint.
What Does Flexible Repayment Actually Mean?
Flexible repayment is a bundle of five features: the interest-only draw, the repayment term, the choice between structures, any fixed-rate conversion, and any prepayment terms. Providers differ most on how many of these they offer.
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.
The draw period is when you borrow, repay, and borrow again up to your limit. The repayment period starts when the draw ends. The line closes to new borrowing and the balance amortizes. Experian’s draw period explainer reports that market-wide, draws typically run five to 10 years followed by a 20-year repayment, and that some plans end the draw with a balloon payment. On the network Lendmire places files with, the structures are shorter and more defined, and they are covered below.
Many banks advertise a fixed-payment conversion option as the flexible choice. It converts part of a drawn balance to a fixed payment, and Yahoo Finance notes that fees can apply each time a balance is converted or reverted. The lines Lendmire arranges do not offer that conversion. Flexibility here comes from choosing the draw structure that matches the plan for the money.
How Does Underwriting Treat a HELOC? Step by Step
Underwriting tests the borrower and the equity. It does not test the rent. A HELOC on a rental is reviewed as a personal credit file secured by the property.
1. Equity. The lender applies a maximum combined loan-to-value (CLTV) by credit tier. On a primary residence, 720 or better supports up to 90% CLTV on lines up to $500,000. Lines above $500,000, up to the $750,000 maximum, are available on a primary residence only, require at least a 700 credit profile, and cap at 75% CLTV. On a second home, the ceiling is also 90% CLTV, and only at 720 or better. On an investment property, the ceiling is 70% CLTV at 700 or better, lines cap at $500,000, and no tier sits above that ceiling.
2. Credit. The program floor is 600 on a primary residence. Second homes start at 640, and investment properties start at 700. The lender uses a single-bureau score keyed to the primary wage earner, and the report must be no more than 90 days old at closing.
3. Debt-to-income. The maximum is 50%, or 45% for scores from 600 to 679. A ratio above 45% needs at least a 680 score. The lender qualifies the borrower on the interest-only payment calculated on the maximum draw, even if the borrower plans to draw less.
4. Valuation. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal. Every line above $500,000 needs a full appraisal, and a borrower can request one at any size.
5. Draw at closing. At least 75% of the line is drawn at closing. That fits a borrower who has a use for most of the money now, and it fits a revolving-reserve strategy poorly.
Every figure here is subject to lender guidelines and full file review. This is not a commitment to lend.
Which Repayment Structures Exist?
The network offers two draw structures, and the choice trades a longer interest-only runway against a longer amortization.
| Feature | 3-year draw structure | 5-year draw structure |
|---|---|---|
| Interest-only draw | 3 years | 5 years |
| Fully amortizing repayment | 17 years | 25 years |
| Available on | Primary residence, second home | Primary, second home, investment |
| Tennessee | 3-year draw / 12-year repayment | 5-year draw / 10-year repayment |
Tennessee shortens both repayment periods, so the two Tennessee figures replace the 17-year and 25-year terms in that state only. In Tennessee, the 3-year structure therefore carries the longer repayment of the two. Everywhere else, the 3-year draw structure suits a borrower who wants the balance amortizing sooner, such as someone funding a project with a defined payback. The 5-year draw structure gives more runway and a longer amortization. It is also the only structure on investment-property lines.
Neither structure has a fixed-rate conversion. Pricing floats through the draw and the repayment period, so a borrower who needs payment certainty should weigh that before choosing a HELOC. A DSCR cash-out refinance on a standard rental, by contrast, is a fixed-term first mortgage.
What Happens When the Draw Period Ends?
The payment steps up, because principal enters the payment for the first time. During the draw, you pay interest on the drawn balance only. When repayment starts, the same balance amortizes over the remaining term, and the payment reflects both principal and interest.
Experian reports that borrowers often see payments more than double at that switch across the broader market. The size of the jump on any given line depends on the balance, the term, and where pricing has moved. Outside Tennessee, the 17-year repayment on the 3-year draw structure produces a bigger step than the 25-year repayment on the 5-year draw structure, which is the cost of paying the balance down sooner. Tennessee reverses that pairing, because its shortened terms are 12 years for the 3-year draw and 10 years for the 5-year draw.
The CFPB’s HELOC brochure makes two points that match this structure. Some plans require principal in the minimum payment during the draw, while others allow interest only. A variable-pricing plan can also change your payment even if you draw nothing more. Both points matter for planning, because an interest-only draw delays the principal due and does not reduce it.
A borrower who cannot carry the repayment phase has a few paths to consider before it starts:
- Pay principal down voluntarily during the draw, after confirming with the lender how prepayment is handled.
- Refinance the balance into a longer fixed-term loan before the draw ends.
- Use a DSCR cash-out refinance to replace the line, where the property’s rental coverage supports it.
Where Does the General Rule Break?
The general rule is that a HELOC suits a homeowner with strong credit and a personal-name deed. Several situations bend or break it.
LLC-owned rentals. Title must be held by the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest difference from a DSCR loan, which can lend to an entity subject to program terms. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
Investment properties generally. Lenders treat rental collateral as riskier, and a BiggerPockets discussion on investment property HELOCs shows investors struggling to find multi-unit lines. On this network, investment lines require 700 or better, cap at $500,000, and carry the 70% CLTV ceiling.
Large lines. A line above $500,000 is available on primary residences only. The credit requirement is 700 or better (720 on the 5-year draw structure), the CLTV caps at 75%, and a full appraisal is required.
Texas. A Texas primary residence is a homestead and caps at 80% combined loan-to-value. Waiting-period and seasoning rules apply to primary residences only, while second homes and investment properties follow their standard tables.
Credit events. A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure history splits by program. One program seasons a foreclosure in seven years and a deed-in-lieu, pre-foreclosure, or short sale in four. The other declines that history regardless of age.
Portfolio size. A borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible.
Property types. Single-family, 2-4 unit, PUD, townhome, and condominium properties are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Geography. This product is brokered only in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. The investor DSCR footprint is wider, at 41 markets including Washington, D.C.
How Should an Investor Choose?
The right structure follows the use of the money, the property, and how long the borrower will hold the balance. This table maps common situations to the structures that tend to fit.
| Situation | Structure that tends to fit |
|---|---|
| Funding a project with a defined payback | 3-year draw, 17-year repayment |
| Needing a longer runway before principal starts | 5-year draw, 25-year repayment |
| Borrowing against a rental held in personal name | 5-year draw (investment structure) |
| Rental held in an LLC | DSCR cash-out refinance |
| Needing payment certainty | DSCR cash-out refinance, or a fixed-term first mortgage |
The first four rows follow the product’s rules. The fifth reflects the lack of a fixed-rate conversion.
It helps to understand how DSCR underwriting differs. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The ratio compares rent to principal, interest, taxes, insurance, and any HOA dues. Many select programs start at 1.00 coverage, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing 1.00 does not mean the property produces positive cash flow, because repairs, vacancy, management, utilities, and capex sit outside the ratio. On a standard rental, a DSCR cash-out refinance generally tops out around 75% LTV and expects about six months of seasoning. A short-term rental cash-out is capped at 70%. Lendmire’s guide to investment property HELOC providers and repayment terms covers the line-of-credit side in more depth, and the complete DSCR loans guide covers the loan side.
The choice is rarely a pure either-or. An owner with strong personal credit, the rental in their own name, and a short-term use for the funds has a workable HELOC case. An owner who holds property in an LLC, wants a fixed term, or has a high debt-to-income ratio is usually better served by a DSCR cash-out.
Questions to Ask Any Provider
A short list of questions separates a flexible line from a merely advertised one:
- Does the draw period allow interest-only payments, and for how long?
- What is the repayment term, and is there a balloon at the end of the draw?
- Is there any fixed-rate conversion, and what does it cost each time?
- Can I prepay principal during the draw, and are there early-repayment fees?
- What share of the line must be drawn at closing, and what is the minimum for later draws?
- Will the lender accept my property type and my title vesting?
- How is my debt-to-income ratio calculated: on the drawn balance or on the full line?
On this network, the last answer is the full line, which is a common surprise for borrowers who plan to draw only part of the limit.
Key Terms Defined
Draw period: The stretch when you can borrow against the line and pay interest only on what you have drawn.
Repayment period: The stretch after the draw ends, when the line closes and the balance amortizes with principal and interest.
CLTV: Combined loan-to-value, which adds the new line to any existing mortgage and divides by the property’s value.
Interest-only payment: A payment covering only the cost of borrowing, which leaves the balance unchanged.
Fixed-payment conversion: A feature on some market HELOCs that converts part of a drawn balance to a fixed payment.
DSCR: Debt service coverage ratio, which compares a rental’s monthly rent to its full monthly obligation of principal, interest, taxes, insurance, and HOA dues.
Frequently Asked Questions
Can I make interest-only payments on a HELOC for an investment property?
Yes, during the draw period. Investment-property lines on this network use a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats throughout and does not convert to fixed. The debt-to-income test uses the interest-only payment calculated on the maximum draw, so the line is sized against the full limit.
Does a HELOC provider test my rental income or my personal credit?
Personal credit and debt-to-income. A HELOC on a rental tests the borrower, while a DSCR cash-out tests the property’s rent against its payment. That is why a borrower with thin personal income but a strong rental often fits DSCR better.
What happens if the property is owned by an LLC?
The HELOC does not work as is. Title must be held by the individual or a revocable living trust. An LLC-owned property needs a vesting change, or a DSCR cash-out refinance instead, subject to lender program eligibility.
How many HELOCs can one borrower hold?
A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the program with the longer runway. An owner with more than 15 financed properties is not eligible.
