The Quick Read: The right line is the one whose draw structure, leverage ceiling, and title rules fit your rental and your exit plan. On investment property, the wholesale network behind Lendmire offers one structure: a five-year interest-only draw, then 25 years of full repayment, up to 70% combined loan-to-value and a $500,000 line, subject to lender guidelines. The payment is interest-only for five years. Then it steps up, because the whole balance starts paying down.
- Interest-only means the balance stays flat during the draw, so none of it is paid off until repayment begins.
- Investment lines in the network need a 700 credit score at minimum, and a higher score does not raise the 70% ceiling.
- Title must sit with you personally or in a revocable living trust, not in an LLC.
- A line on a rental you own differs from a line on your home that funds a rental purchase, and you should compare the two before you apply.
- Plan the exit before year five: sell, refinance, or pay the balance down. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Key Terms Defined
Draw period: the stretch of time when you can borrow against the line, and the payment is interest-only.
Repayment period: the stretch after the draw ends, when you can no longer borrow and the balance is paid off with principal and interest.
Interest-only payment: a payment that covers only the interest on what you have drawn, so the balance does not shrink.
CLTV (combined loan-to-value): all loans against the property, first mortgage plus the line, divided by the property’s value.
DTI (debt-to-income ratio): your monthly debts as a share of your monthly income.
Lien position: where a loan stands in line to be repaid if the property is sold. A first lien is paid before a second lien.
DSCR loan: an investor loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
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.
Can You Get a HELOC on a Rental at All?
Yes, but far fewer lenders offer it than offer lines on a primary home. A home equity line of credit is a revolving line you can draw on repeatedly, and most lenders write it against the home you live in. A line secured by a non-owner-occupied rental is a narrower product with stricter terms.
Investors use the product in two ways, according to RentalRealEstate.com. The more common way is a line on the investor’s own home, with the money used for rental purchases. The less common way is a line placed directly on the rental, which fewer lenders offer and with tougher requirements.
Investor discussions on BiggerPockets show how often lenders enter and leave this space. Some stop offering non-owner-occupied lines altogether. That churn is the reason a broker with several wholesale lenders matters here. A single bank’s answer of “we don’t do that” tells you about one bank, not the market.
Wording matters too. Some lenders write lines on rentals but do not call them HELOCs, so asking for a line of credit secured by investment property can open doors that the HELOC label does not.
How the Line Works From Draw to Payoff
The line moves through two phases, and the interest-only feature lives in the first one. NerdWallet describes the same split: a draw period in which you borrow, then a repayment period in which you pay principal plus interest.
On the network’s investment-property lines, the timeline looks like this:
1. Closing. At least 75% of the line is drawn at closing. Interest runs on what you have drawn, so most of the line carries interest from day one.
2. Years one through five (draw). Payments are interest-only. Subsequent draws after closing commonly carry a $1,000 minimum on programs that state one.
3. Years six through 30 (repayment). Borrowing stops. The full balance amortizes over 25 years.
Interest accrues only on the drawn balance, not the full limit, as NerdWallet’s HELOC calculator page explains. An undrawn slice costs nothing in interest. On an investment line, that slice is small because of the 75% drawn-at-closing requirement.
Pricing floats. It is built from an index plus a margin, as the CFPB’s overview of home equity lines explains, and the payment can change month to month. Some lines elsewhere let you convert part of the balance to a fixed rate. The investment lines in this network do not. Pricing floats through both the draw and the repayment period.
What Happens When the Draw Ends?
The payment steps up, and the reason is arithmetic. An interest-only draw leaves the full balance untouched for five years. When repayment starts, that entire balance must be paid off over the remaining 25 years. NerdWallet calls this repayment shock.
Here is the same balance in both phases, with pricing held constant:
| Feature | Draw period | Repayment period |
|---|---|---|
| Borrowing | Allowed | Stopped |
| Payment covers | Interest only | Interest plus principal |
| Balance | Stays flat | Falls each month |
| Length (investment line) | 5 years | 25 years |
| Payment direction | Moves with the index | Higher than draw, still moves |
Extra principal paid during the draw softens the step-up, because it shrinks the balance that gets amortized later. Interest-only does not mean the cost is lower over the life of the line. It means the cost is deferred.
Key Underwriting Steps, in Order
Step 1: Property type. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not offered.
Step 2: Title and vesting. Title must be held by you individually or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a different product.
Step 3: Listing status. In several states in the footprint, a property listed for sale or listed within the past 60 days is ineligible.
Step 4: Combined leverage. The ceiling on an investment line is 70% CLTV. The maximum line is the property’s value times 70%, minus your first mortgage balance, capped at $500,000. A thin equity position can leave little or no room.
Step 5: Credit. The minimum is 700. Both the 720 and 700 tiers reach the same 70% CLTV, so credit above 700 buys eligibility, not leverage. The lender reads a single-bureau score keyed to the primary wage earner, and the report can be no more than 90 days old at closing. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, a foreclosure needs seven years. A deed-in-lieu, pre-foreclosure, or short sale needs four.
Step 6: DTI. The maximum is 50%. Lenders review your file on the interest-only payment calculated on the maximum draw, not only on what you plan to borrow. That detail trips up many borrowers, because at least 75% of the line is drawn at closing and the file is underwritten as if the line were fully used.
Step 7: Valuation. Because an investment line caps at $500,000, and full appraisals begin only above $500,000, an investment line normally runs on an automated valuation with no traditional appraisal. A higher CLTV may call for a secondary valuation, and you may request a full appraisal in any case.
Step 8: Portfolio limits. A borrower is limited to three lines in total, and an owner with more than 15 financed properties is not eligible.
Notice what is missing. A signed lease does not qualify the line, and a vacant unit does not disqualify it. Occupancy type and your borrower profile decide the outcome. Business bank statements, where used for income, require a 680 minimum, but investment lines already floor at 700, so that test never becomes the binding constraint.
How to Judge the Best Investment Property HELOC Program for Your Situation
The best program depends on your property, equity, credit, title, and how long you plan to hold the debt. No single lender or structure wins for every borrower, so a transparent checklist beats a ranked list. Run your file through these questions:
- Do you own the rental already? A line on the rental needs equity in it today. It cannot finance a property you are still buying.
- Is title personal or in a revocable trust? If an LLC holds it, this product is out until vesting changes.
- Is your score at or above 700? Below that, an investment line is closed, and other products apply.
- Does the equity math work at 70% CLTV? If your first mortgage already uses most of that room, the line may be small.
- Do you need more than $500,000? An investment line cannot reach it.
- Can you carry the repayment step-up? Test the repayment phase, not just the draw.
This is also where a broker earns its place. A broker shops several wholesale lenders, reads each one’s guidelines, and matches the property, credit profile, and leverage need to the program that fits. The choice of lender depends on the file, and more affordable-looking draw terms can hide the tightest overlays.
Two Routes: A Line on the Rental or on Your Home
Many investors never put a line on the rental at all. They borrow against their own residence instead, which can be a better fit for some files and a worse one for others.
| Factor | Line on the rental | Line on your primary home |
|---|---|---|
| Collateral at risk | The rental | Your home |
| Draw structure | 5-year draw, 25-year repayment | 3-year draw with 17-year repayment, or 5-year draw with 25-year repayment |
| Ceiling | 70% CLTV | Up to 90% CLTV, only at a 720-or-better credit profile |
| Maximum line | $500,000 | Up to $750,000, with lines above $500,000 requiring a full appraisal |
| Credit minimum | 700 | 600 program floor |
The home route offers more leverage and flexibility. It also puts the roof over your head behind a business decision, and that risk deserves a straight look before you sign. The rental route keeps the risk on the investment, but it asks for more credit and gives less leverage.
When a HELOC Is the Wrong Tool
A HELOC is the wrong tool when your title, credit, or size needs fall outside its box, or when you want fixed pricing you can underwrite with confidence. A few situations point elsewhere:
- Title sits in an LLC. A DSCR cash-out refinance commonly accommodates LLC borrowers, subject to program terms.
- Credit is under 700. DSCR programs reach lower score tiers on many files.
- You need more than $500,000. DSCR loans run up to $3,000,000 on standard programs (smaller balances available through select lenders).
- You own many properties. The line stops at 15 financed properties, while DSCR qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
- You want a fixed structure. DSCR loans center on a 30-year fixed term, with 40-year and interest-only options through select lenders.
On a DSCR cash-out refinance, most of the network tops out around 75% LTV on standard rentals, with about six months of seasoning as the common expectation. Short-term rentals sit lower: the cash-out ceiling is 70% on short-term-rental collateral. Coverage works differently from a HELOC, too. Many select programs start at a 1.00 coverage ratio, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. For the full picture, see Lendmire’s complete DSCR loans guide. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
A DSCR cash-out replaces your first mortgage. A line sits behind it. If your existing first mortgage is a good one, leaving it untouched is the main reason to prefer a second-position line, and NerdWallet notes that getting a line does not change your current home loan.
The Risks You Should Stress-Test
Three risks matter most, and each can be tested before you commit.
The end-of-draw step-up. Run your rental’s cash flow against the repayment phase, not the draw phase. If the property only works while payments are interest-only, the plan has a deadline built in.
Variable pricing. The payment moves with the index, and an interest-only payment still rises when the index rises. Test the property with the payment meaningfully higher than today’s.
Vacancy and carrying cost. A line does not care whether the unit is occupied. A vacant month still owes the payment. Keep reserves for repairs, vacancy, management, and utilities, because none of these show up in a lender’s coverage math.
That last point applies to DSCR as well. A coverage ratio compares rent to the housing payment only, so clearing 1.00 does not mean positive cash flow.
Choosing Your Exit Before Year Five
Every interest-only draw ends, so the exit plan is part of the loan. You have three clean choices.
1. Pay down during the draw. Extra principal now shrinks the repayment shock later.
2. Refinance before the draw ends. This means replacing the line with a longer-term structure.
3. Sell the rental. The proceeds retire the line.
Pick one before closing. Waiting until year five narrows your options, because credit, value, and equity all move in the meantime.
Frequently Asked Questions
Is every investment HELOC interest-only during the draw?
Most are, but not all. The credit agreement sets the payment terms, and some lines build in principal. On the network’s investment lines, the five-year draw is interest-only.
Can an LLC hold title on the line?
No. Title must be held by you personally or by a revocable living trust. A property already deeded to an LLC needs a vesting change first. A DSCR cash-out refinance, subject to program terms, is the usual alternative.
Does a higher credit score raise my leverage?
Not on an investment line. Scores of 700 and 720 both reach the same 70% CLTV, so a higher score buys eligibility, not extra leverage.
Do I need an appraisal?
Usually not. Because an investment line caps at $500,000, it commonly runs on an automated valuation. A higher CLTV may call for a secondary valuation, and you can request a full appraisal at any time.
What if my rental is vacant?
Vacancy does not disqualify the line, and a signed lease does not qualify it. The lender reviews the property type, title, equity, and your credit profile. You still owe the payment during empty months, so hold reserves.
