The Quick Read: The best program depends on your credit, your equity, and how the rental is titled. A line on a mortgaged rental sits behind your first loan as a second lien, so the first mortgage’s rate, term, and payment do not change. Through Lendmire’s wholesale network, an investment-property line is qualified on you, not on the rent. It tops out at 70% combined loan-to-value (CLTV), subject to lender guidelines.
- Ceiling: 70% CLTV on an investment property, with a $500,000 maximum line.
- Credit: 700 is a hard floor. A 720 score buys no extra leverage.
- Title: The property must be in your name or a revocable living trust. An LLC cannot hold title.
- Draw structure: Investment lines run a 5-year interest-only draw, then a 25-year repayment.
- Availability: These lines are brokered in 16 states only, not the full DSCR footprint.
A bank-style line on a rental is a narrow product. Plenty of lenders skip it. The ones that write it are strict about credit, title, and how much total debt sits on the property. Lendmire is a mortgage broker, not a lender. It places these files with select wholesale partners, which means the “best” program is the one that fits your scenario, not a single name on a list.
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 Is an Investment Property HELOC?
A home equity line of credit (HELOC) is a revolving credit line secured by property. Equity is the property’s value minus what you owe on it. The CFPB describes a HELOC as an open-end line you can borrow against repeatedly. You can draw up to your limit during a set draw period, and payments float because the pricing is variable.
On a rental, the collateral is the investment property itself. That changes how lenders see it. NerdWallet notes that lenders see higher default risk on rentals, so the lender pool is smaller and borrowing limits are lower than on a primary home. Expect fewer choices and tighter rules.
How Does the Line Sit Behind Your First Mortgage?
It records as a second mortgage. Your first loan stays exactly as it is, with its own rate, term, and payment. The new line is junior to it. If the property were ever sold in a default, the first lender gets paid first.
This is the main appeal. Say you hold a rental with a low-cost first mortgage you would hate to replace. A cash-out refinance would swap that loan for a new one. A second-lien line leaves it alone.
The line can also sit in first position when a rental is owned free and clear. With a first mortgage in place, though, you are always in second position, and that is where the math gets tight.
How Much Room Do You Actually Have?
Your room is the 70% CLTV ceiling minus what you already owe. CLTV is the first mortgage balance plus the new line, divided by the property’s value. Every recorded lien counts, so a prior second mortgage or a tax lien shrinks the space.
Run it on a property valued at $400,000. At 70% CLTV, total debt on the property can reach $280,000. If your first mortgage already sits near that figure, you have close to no room. If it sits well below, the remainder is your possible line.
Three outcomes show up in practice:
- Zero room. The first mortgage already uses most of the 70%. No line is possible.
- Room, but under the minimum. Lines start at $25,000 in most states. A sliver of equity below that does not qualify.
- Room above the minimum. The line is sized to the gap, up to the $500,000 investment maximum.
Lenders keep a cushion on purpose. That cushion is why a rental with a modest first mortgage balance is the strongest candidate.
What Credit and Debt Ratios Do These Programs Want?
On an investment property, 700 is the minimum credit score, and there is no tier beneath it. A 720 and a 700 both reach the same 70% CLTV. Higher credit above 700 buys you eligibility, not extra leverage. The network’s general floor is 600, but that applies to other occupancy types, not investment lines.
The debt-to-income ratio (DTI) compares your monthly debts to your monthly income. Maximum DTI is 50%. It drops to 45% for credit profiles from 600 to 679, though investment already floors at 700. The payment is qualified on the interest-only amount at the maximum draw, so a large line is judged as if fully drawn.
Credit is pulled from a single bureau score model tied to the primary wage earner. The report can be no more than 90 days old at closing, and rescoring is not available.
Because this is a personal-profile product, your first mortgage on this rental counts in your DTI. Experian reports the same pattern across the broader market: lenders there commonly look for DTI below 40% to 50%, and the existing mortgage on the property is part of that count. Those are market figures. The network figure is the 50% maximum above.
Who Underwrites What? HELOC vs. DSCR Cash-Out
The difference is the test being applied. A bank-style line is reviewed on you: credit, income, and total debt. A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR means debt service coverage ratio, the rent compared to the full monthly housing obligation.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Reviewed on | Your credit and DTI | Rental coverage |
| Lien position | Second (or first if free and clear) | First |
| Title | Individual or revocable trust | LLC allowed, per lender program |
| Rate behavior | Floats, never fixed | Fixed structures available |
On a DSCR cash-out, most programs in the network top out around 75% LTV with about 6 months of seasoning. Seasoning is the waiting period between buying and refinancing. That is a different route than a line, and Lendmire’s piece DSCR HELOC vs DSCR Cash-Out Refinance on a Rental That Still Has a First Mortgage walks through the choice.
Clearing 1.00 coverage on a DSCR loan is not the same as positive cash flow. Repairs, vacancy, management, and utilities sit outside that calculation. Keep that in mind when you weigh the two routes. For more on how those loans work, see the complete DSCR loans guide.
Why Do Lenders Decline Mortgaged Rentals?
Most declines trace back to a short list of causes. Each has a different fix.
| Reason | What it means | Next step |
|---|---|---|
| Too much total debt | CLTV above 70% | Wait, pay down, or consider another route |
| Entity title | Property sits in an LLC | Change the vesting, or use a DSCR cash-out |
| Credit under 700 | Below the investment floor | Build credit, or look at DSCR |
| Ineligible property | Co-op, condotel, manufactured home, log home | Not offered under this program |
| Too many financed properties | More than 15 financed | Not eligible |
| Prior liens | Another second or a tax lien | Clear it, then reapply |
A property listed for sale, or listed within the past 60 days, is also ineligible in several states, including Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington. New Mexico and Ohio set a CLTV cap that depends on your credit profile.
Does Your First Mortgage’s Paperwork Get a Vote?
It can. Your first mortgage note and deed of trust may restrict additional liens. Read them before you apply. Some first mortgage contracts treat a new recorded lien as a default trigger or require lender consent.
Do not assume it is fine because a second lien is common on primary homes. Rentals are different, and the terms of your first loan are specific to you. If the document is unclear, a broker can help you read what it says before an application goes in. A qualified attorney is the right person to interpret a restrictive covenant.
Title, Entity, and Property-Type Rules
Title is the sharpest difference from a DSCR loan. The individual borrower or an inter vivos revocable living trust must hold title, either fee simple or leasehold. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. If your rental is already deeded to an LLC, you need a vesting change first, or a DSCR cash-out instead.
That LLC point matters for many investors. The entity that protects you from liability is the same entity that blocks this product. Moving title can have knock-on effects with your first mortgage and your insurance, so check before you act.
Eligible property types include single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. A 2-4 unit property requires a 640 minimum score on one of the structures, which an investment profile clears anyway at 700. Modular factory-built homes are eligible on one structure only. Not offered: manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agriculturally zoned properties.
You are limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage structure and $750,000 on the longer-runway structure. Owning more than 15 financed properties makes you ineligible.
What Does Valuation Look Like?
An investment line caps at $500,000, and full appraisals begin only above that amount. So an investment line normally uses automated valuation, with no traditional appraisal. A higher CLTV may call for a secondary valuation. You can also ask for a full appraisal in any case.
That is useful if you want certainty about the number. Automated values can miss recent renovations or unusual features.
How Do the Draw and Repayment Work?
Investment lines run a single structure: a 5-year interest-only draw, then a 25-year fully amortizing repayment. Primary residences and second homes can choose a 3-year draw with a 17-year repayment instead. Investment cannot.
Key mechanics:
- At least 75% of the line is drawn at closing.
- Pricing floats through both the draw and repayment period. It never converts to fixed.
- Minimum draw after closing is $1,000 (higher in Texas) on the longer-runway structure.
- Line size runs from $25,000 up to $500,000 on an investment property. Anything above $500,000 is primary residence only.
Payment shock is real. The interest-only phase keeps the payment light. When repayment begins, principal is added. Plan for that step-up before you draw.
Which Landlord Are You?
The investor with a low first mortgage and real equity. You are the best fit. Check your CLTV, confirm title is in your name, and a line may work.
The investor whose rental is in an LLC. A line is not available as-is. A DSCR cash-out refinance may suit you better, subject to program terms.
The investor with a score under 700. The 700 floor is firm. A DSCR route, which weighs rental coverage, may be worth reviewing. Sub-1.00 coverage is available through select lenders in the network, with leverage and terms adjusted.
The investor who wants a fixed payment. A line never converts to fixed. A closed-end second or a cash-out refinance may suit you better. The CFPB explains that a home equity loan pays out as a lump sum with a fixed or adjustable rate.
What Are the Risks?
The rental secures both loans. Miss payments on the line and the property is at risk, even if your first mortgage is current. Experian points out that the line is secured by the rental, so missed payments can lead to foreclosure.
Floating pricing is the second risk. Your payment can change without any change in your own finances. Third is your debt load. The line shows up on the next lender’s view of your DTI, which can make a later purchase harder.
Run a use-of-funds test before you draw. If the money buys a down payment or funds repairs that lift rent, the line can pay for itself. If it covers a shortfall, step back.
How to Shop and What to Ask
A broker shops multiple wholesale lenders and matches your scenario to the program. Before you apply, gather:
- Your first mortgage statement and a current lease or rent proof.
- Title or vesting documents showing the owner of record.
- Proof of income and your credit profile.
- A list of every lien on the property, including any prior second.
Ask each lender: What is the maximum CLTV on my occupancy? Who must hold title? Is pricing variable through repayment? What happens at the end of the draw period? Does my first mortgage restrict additional liens?
Availability is limited. These lines are brokered in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the DSCR footprint of 41 markets, including Washington, D.C.

Frequently Asked Questions
Can I get a HELOC on a rental that still has a mortgage?
Yes, through select wholesale lenders, as a second lien behind your first loan. On an investment property the network ceiling is 70% CLTV with a 700 minimum score. Eligibility depends on title, valuation, and total debt, subject to lender guidelines and file review.
Can an LLC-owned rental qualify?
No. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. Title must sit with you or a revocable living trust. If the property is already in an LLC, a vesting change or a DSCR cash-out refinance is the usual path.
Does the line change my first mortgage?
No. The first mortgage keeps its rate, term, and payment. The line is a separate loan recorded behind it. Read your first mortgage documents for any limits on additional liens before you apply.
Is a line on a rental better than a cash-out refinance?
It depends on your first mortgage and your goal. A line keeps a low-cost first loan intact but floats in price and is qualified on you. A DSCR cash-out replaces the first loan and qualifies primarily on rental income, subject to lender guidelines.
How much can I borrow?
Lines on an investment property run from $25,000 to $500,000, capped by 70% CLTV. The first mortgage balance and any other liens reduce what is left. Where the gap is under the minimum, no line is possible.
