The Quick Read: An investment property HELOC is a separate credit line recorded behind your existing first mortgage, so the first loan keeps its current terms while you borrow against the equity that remains. The lender counts your first mortgage balance against your combined leverage, but it does not change the first loan’s rate, term or payment. Across Lendmire’s wholesale network, this option is narrow and has real limits.
- The ceiling on an investment property line is 70% CLTV (combined loan-to-value, all liens divided by value), with a $500,000 maximum line and a $25,000 minimum.
- Your credit profile needs to be 700 or better. A 720 score buys no extra leverage on an investment line.
- Title must sit in your own name or a revocable living trust. An LLC cannot hold title on this product.
- The line is underwritten on you (credit, debt-to-income, equity), not on the rent the property earns.
- Pricing floats for the life of the line and never converts to fixed.
Subject to lender guidelines and full file review; not a commitment to lend.
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 an Investment Property HELOC Works
A HELOC is a line of credit secured by property equity. Equity is what the property is worth minus what you owe on it. You borrow during a draw period, then the line moves into repayment.
On an investment property line in Lendmire’s network, the draw period is five years, interest-only. Repayment follows over 25 years on a fully amortizing basis. Pricing floats through both periods and never converts to fixed.
Two features separate this from the line most people picture. First, the lender expects a large first draw. At least 75% of the line is drawn at closing, so this works as a one-time cash tool, not a standby fund you tap as needed. Second, the line sits on a rental, not your home, so the lender treats it as higher risk. That is why the limits are tighter than on a primary-residence line.
Not every lender offers these at all. NerdWallet notes that not all lenders offer a HELOC on an investment property and that requirements run strict. A broker with several lenders to place files with can check which ones fit a given property and borrower.
Why the First Mortgage Stays Untouched
Think of liens as a line at a counter. Your first mortgage is first in line. A second-lien HELOC stands behind it as its own loan, with its own note and its own payment.
Opening the second loan does not rewrite the first. The first loan keeps its existing rate, term and payment. Lendmire’s network treats it the same way.
Here is what the first mortgage does contribute to the new line’s math:
- Its balance counts toward your combined leverage. A bigger first balance leaves less room.
- Its payment counts in your debt-to-income ratio.
- Its rate never enters the sizing at all. A very low coupon and a high one use up the same amount of equity.
The lien position is a choice you make on purpose. A first-lien line on a property that already has a mortgage would pay that mortgage off, which defeats the goal. To keep the loan you have, you pick second position. If there is no first mortgage at all, the line must go in first position and the keep-the-low-first benefit disappears, because there is nothing to keep.
Step by Step: How Underwriting Treats the Line
Here is the order in which a lender looks at a rental-property HELOC.
1. The equity test
Take the CLTV ceiling, multiply by value, then subtract everything owed ahead of you. That includes the first mortgage and any other lien, such as a second mortgage or tax lien. Everything comes out of the same budget.
On an investment property, the ceiling is 70% CLTV. Picture a rental worth 100 units with a first mortgage of 50 units. Total debt can reach 70 units, so the new line can be at most 20 units.
| First mortgage balance (% of value) | Total debt allowed | Room for a line |
|---|---|---|
| 30% | 70% | 40% of value |
| 50% | 70% | 20% of value |
| 65% | 70% | 5% of value |
| 70% or more | 70% | — |
Two other limits can bind before the CLTV does. On an expensive property with a small first balance, the $500,000 maximum line caps you first. On a modest property with a large first balance, the room left may fall under the $25,000 minimum, and then no line fits.
For context, Experian reports that lenders in the wider market typically cap investment-property HELOCs at 80% LTV. That is a market-wide statistic. The investment property ceiling in Lendmire’s network is 70% CLTV.
2. Valuation
An investment line caps at $500,000, and full appraisals are required only on lines above $500,000, so these lines ordinarily run on an automated valuation with no traditional appraisal. A higher CLTV can trigger a secondary valuation. You can also ask for a full appraisal. The rent schedule and operating-income appraisal forms used on DSCR files are not part of this lane.
3. Qualifying on you, not the property
A DSCR cash-out loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC works the other way. The property is the collateral, but the lender underwrites the borrower: credit, debt-to-income and equity.
Experian says investment-property lines typically demand a higher credit score, lower debt-to-income and stronger reserves than lines on a primary home. The network’s own numbers fit that picture:
- Credit profile of 700 or better, with no tier below it.
- Debt-to-income of 50% at most. The lender qualifies you on the interest-only payment, calculated on the maximum draw.
- Credit report no more than 90 days old at closing.
- Bankruptcy needs 4 years of seasoning. Foreclosure-family history follows a 7-year and 4-year seasoning path on investment files, depending on the event.
4. Title and documents
Title has to be held by you as an individual or in a revocable living trust. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title. This is the sharpest structural difference from a DSCR loan, and a rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead. Lenders also confirm that the first lender’s documents allow a second lien.
5. Exposure limits
A borrower is limited to three lines across the programs. An owner with more than 15 financed properties is not eligible. Eligible property types are single-family, 2-4 units, PUD, townhome and condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not offered.
6. Funding
The line funds with at least 75% drawn at closing. Pricing floats from that point forward.
Availability matters too. HELOC placements run through Lendmire’s 16 full-service states, which is narrower than the 41-market DSCR footprint, including Washington, D.C.
Key Terms Defined
CLTV (combined loan-to-value): The total of all loans against a property divided by its value.
Second lien: A loan recorded behind the first mortgage, with its own note and payment.
Draw period: The stretch when you can borrow from the line, paying interest only on this product.
Repayment period: The stretch after the draw ends, when you pay down principal and interest until the balance is gone.
Automated valuation: A computer-generated value estimate used in place of a full appraisal.
Open-end line: Credit you can borrow from, repay and reuse within limits, as opposed to a one-time loan.
Where the General Rule Breaks
The line works best for a narrow type of borrower. These are the named edge cases.
No first mortgage. The line must go in first position. You get the cash, but nothing is being preserved.
Rental held in an LLC. Title rules block the line. A vesting change into your name or a revocable trust can fix it, though you should weigh that change with your own advisers. A DSCR cash-out is the usual alternative.
Large first balance. You run out of CLTV room first. At 65% of value on the first, only 5% remains.
Small first balance on an expensive property. The $500,000 cap binds before the CLTV does.
Thin cash flow. Clearing 1.00 on a DSCR test does not mean positive cash flow, because DSCR compares rent only to the full monthly housing payment. Repairs, vacancy, management, utilities and capital costs sit outside the ratio. A second payment on a property already running tight can push it negative. 1.00 is where many select DSCR programs start, and a separate select-lender path goes below 1.00 with leverage and terms adjusted. A HELOC is judged on you personally, not on that ratio.
A later refinance of the first loan. The second lien must be paid off or subordinated before the first can be refinanced. That makes the first mortgage harder to change later. It is the main hidden cost of the second-lien route.
Payment shock. The federal consumer-finance regulator’s HELOC explainer says HELOCs usually carry variable rates and that payments are often significantly higher once repayment begins. Some plans also require the whole balance at once when repayment starts. Its HELOC booklet adds that the variable rate is tied to a public index. The same explainer says some plans allow a fixed-rate conversion on part of the balance. The investment lines in Lendmire’s network never convert, so the floating price runs for the life of the line.
Funding from another property. Some investors draw on a primary-residence HELOC instead, to fund a down payment on a rental. That is a different product, secured by the home, and it puts the home at risk instead of the rental.
HELOC, Cash-Out Refinance or DSCR Cash-Out?
If your first mortgage is cheap and your cash need is modest, a second lien can beat replacing the loan. Only the new money is priced at today’s terms. If you need more cash than the room left, replacing the first loan through a DSCR cash-out may be the only way to get there.
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| Your first mortgage | Stays in place | Replaced |
| Reviewed on | You: credit, DTI, equity | Rent covering the payment |
| Title | Individual or revocable trust | LLC allowed, per program |
| Leverage | 70% CLTV, investment | 75% standard; 70% STR |
| Best fit | Modest cash need, low first | Larger need, many properties |
For a standard rental, a DSCR cash-out tops out around 75% LTV in most of the network, with about 6 months of seasoning as the common expectation. On short-term-rental collateral the ceiling is 70%. DSCR files also take loan sizes from roughly $100,000 up to $3,000,000, well above a HELOC’s $500,000 line cap. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
The qualification trade-off is the deciding factor for many landlords. A HELOC uses personal income and debt-to-income, which can be hard for a self-employed owner or someone carrying many loans. A DSCR loan reads the property’s rent and suits portfolio owners better. The strongest files clear both tests: enough equity and enough rental coverage. You can read the complete DSCR loans guide for how that rent-based review works.
Does Keeping the Low First Make Sense?
A HELOC fits if:
- Your first mortgage is well below what a new loan would cost.
- Your first balance leaves meaningful room under 70% CLTV.
- The property is in your name or a revocable trust.
- You have one defined use for the cash, such as a payoff or a repair project.
- You can carry a second, floating payment even if the rental is vacant for a stretch.
Look elsewhere if:
- Title sits in an LLC and a vesting change is not workable.
- Your cash need is bigger than the room left.
- You plan to refinance the first loan soon.
- Your credit profile is under 700.
- Your cash flow is already thin.
The cost of being wrong is concrete: two payments, a balance that floats, and a lien that complicates a later refinance of the first loan. The line is secured by the rental, so missed payments put that property at risk.
Common Misconceptions
A HELOC changes my first mortgage. It does not. It is a separate loan behind the first one.
Better credit buys more leverage. Not on an investment line. A 720 profile and a 700 profile both reach the same 70% CLTV, so a higher score buys eligibility rather than leverage.
It works like a standby line. Not really. Most of the line is funded up front, so it behaves more like a one-time payoff tool.
The price is fixed. It floats through draw and repayment on every investment line in the network.
Any bank will do this. Many will not. Requirements are strict, and the options are fewer than for a primary-home line.
Frequently Asked Questions
Can I get a HELOC on a rental I own through an LLC?
Not as it stands. LLCs, corporations and partnerships cannot hold title on this product. You can move the deed to your own name or a revocable living trust, or you can use a DSCR cash-out refinance, which can work with entity title subject to program terms. Talk through the vesting change with your advisers before deeding anything.
Does the interest rate on my first mortgage limit how much I can borrow?
No. Only the first mortgage’s balance counts toward combined leverage, and its payment counts toward debt-to-income. Two first mortgages with the same balance leave the same room under the 70% CLTV ceiling, whatever their terms.
How large can an investment property line be?
Between $25,000 and $500,000 on an investment property. A line above $500,000 exists only for primary residences, so an investment property never reaches it. Room under 70% CLTV usually binds first.
What happens when the draw period ends?
On an investment line, the five-year interest-only draw ends and a 25-year repayment begins on a fully amortizing basis. Principal comes due on top of interest, so the payment usually steps up. Pricing keeps floating and does not convert to fixed.
Does a HELOC on my rental put my home at risk?
The line is secured by the rental, not your home. Missing payments puts that property at risk. A line drawn on a primary residence to fund a rental purchase works the other way and puts the home at risk.
