The Quick Read: An investment property HELOC behind your existing first mortgage is a second-lien line that leaves the first loan untouched, but few lenders write it, and on Lendmire’s wholesale network it caps at 70% combined loan-to-value with a 700 minimum credit score and a $500,000 maximum line. The lender pool is small, so a broker that shops several wholesale lenders can save you a lot of dead-end calls.
- The line records behind your first mortgage, which keeps its own balance, term, and payment.
- Combined leverage counts every lien, so your first mortgage balance eats into the room first.
- Approval leans on you personally: credit, debt-to-income, and equity, not the rent.
- The rental must be titled to you or your revocable living trust, not an LLC.
- If a replacement loan fits better, a DSCR cash-out refinance qualifies primarily on property-level rental income, subject to lender guidelines.
How Does a HELOC Work When the Rental Already Has a First Mortgage?
A home equity line of credit (HELOC) on a financed rental is a second mortgage. It sits in second position behind your first loan. The first lender is paid first if the property is sold or foreclosed, and the new lender takes what is left.
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.
You draw from the line as needed. Early on you make interest-only payments. Later the balance amortizes. NerdWallet notes that an investment-property HELOC is possible, but the lender pool is smaller than for a primary home, not every lender offers one, and qualification is strict.
Here is what the product looks like on Lendmire’s network for an investment property:
- Leverage: 70% combined loan-to-value, whether your credit is 700 or 720 and up. Credit above 700 buys eligibility, not extra leverage.
- Size: a maximum line of $500,000. Larger lines exist only on primary residences.
- Structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. The price floats through both periods and never converts to fixed.
- Draw at closing: at least 75% of the line is drawn when the loan closes.
Every figure is subject to lender guidelines and a full file review. This is not a commitment to lend.
Why Do So Few Lenders Write This Loan?
Few lenders write it because a rental line carries more risk for them than a line on your home. Rent depends on a tenant paying. Many big banks and other depository institutions keep their equity lines for owner-occupied homes, and some write rental lines only in first position.
Market surveys put the typical cap on investment-property lines at 80% of value, per Experian. That is a market-wide statistic. On Lendmire’s network, an investment line caps at 70% combined loan-to-value.
In practice, three groups write these lines:
- Local and portfolio lenders. They hold loans on their own books and can bend to a scenario. Appetite varies from one to the next.
- Large retail lenders. Many restrict equity lines to primary homes. Some will lend against a rental, but only on narrow terms.
- Wholesale lenders reached through a broker. A broker sees many guidelines at once and matches your property and profile to a program that fits.
The best lender for your situation depends on your title, credit, leverage need, and property type. Nobody can name a winner without those facts.
How Much Can You Borrow? The Math
Your maximum line is the combined cap times the property value, minus everything already secured against it. On Lendmire’s network the cap for an investment line is 70% combined loan-to-value, and the line can never exceed $500,000.
Combined loan-to-value (CLTV) adds every lien and divides by the property value. The line counts at its full limit, not only the drawn amount. Here is how the room shrinks as your first mortgage grows:
| First mortgage vs. value | Room under a 70% cap | Result |
|---|---|---|
| 50% of value | 20 points of value | Roomy |
| 65% of value | 5 points of value | Tight |
| 72% of value | None | No line possible |
Say you own a rental where the first mortgage sits near half the value. You have about 20 points of value to work with, and the $500,000 ceiling only matters on a high-value property. Any second mortgage, home equity loan, or tax lien joins the first in the math. Pull the payoff from your latest mortgage statement and list every lien before you shop.
Check Your First Mortgage Before You Shop
Read your first mortgage documents before you apply for anything. Some loan agreements restrict adding other liens to the property. If the wording is unclear, ask the first lender or a real estate attorney.
Title matters just as much. A rental held in an LLC cannot take this line. The same goes for corporations, partnerships, and irrevocable, blind, or land trusts. Title must sit with you personally or in a revocable living trust. Retitling a mortgaged property can create problems with the first loan, so do not move title without checking.
Is the property already deeded to an LLC? Then you either change the vesting after confirming the first mortgage allows it, or you look at a DSCR cash-out instead. DSCR financing can fit LLC-held rentals, subject to program terms.
What Do Lenders Look For?
These lines are underwritten on you, not on the rental’s income. Lenders review your credit, your debt-to-income ratio (DTI), your equity, and the property itself.
The network’s investment-line standards:
- Credit: 700 minimum. There is no tier beneath it.
- DTI: 50% maximum, calculated on the interest-only payment at the maximum draw. Your existing mortgage payment counts.
- Exposure: up to three lines per borrower. Owning more than 15 financed properties makes a borrower ineligible.
- Valuation: a line capped at $500,000 is ordinarily valued by automated valuation, often with no traditional appraisal. NerdWallet adds that some lenders order more than one appraisal on investment properties, so the method varies by lender.
- Credit report: no more than 90 days old at closing, with no rescores.
A typical document set includes your first mortgage statement, proof of insurance, title information, and a lease or rental history. A property listed for sale, or listed recently, is ineligible in several states.
The network is also narrower here than on the DSCR side. These lines are available in 16 full-service states, while the DSCR footprint spans 41 markets, including Washington, D.C.
Which Properties Qualify, and Which Do Not?
Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Modular factory-built homes are eligible on one of the two wholesale programs behind these lines. Lenders may also set a higher credit score for 2-4 units.
The following are not offered: manufactured homes, co-ops, condotels, log homes, commercial property, mixed-use property, and agricultural zoning. Barndominiums are also outside the network’s programs.
Keep the First Mortgage or Replace It?
Keep it when your first mortgage is worth keeping and you have the equity, credit, and DTI room for a second line. Replace it when your personal file is stretched, your title is an LLC, or you want more cash than a 70% combined cap allows.
| Factor | HELOC (second lien) | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Reviewed on | Your credit, DTI, equity | Property rent covering the payment |
| Title | You or revocable trust | LLC possible, subject to program terms |
| Leverage ceiling | 70% CLTV | Around 75% LTV on standard rentals |
| Payment | Floats | Fixed structures are the spine |
A DSCR loan compares rent to the full monthly obligation: 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. Cash-out files typically expect about six months of seasoning. For the full picture, see the complete DSCR loans guide.
One caution: clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, and utilities sit outside the calculation.
If your rental still carries a second mortgage, that changes the room and the options. Lendmire’s piece on investment property HELOC options when you already have a second mortgage covers that case.
Who Should Skip This Route?
Skip it if any of these describe you:
- Your first mortgage already sits near the 70% combined ceiling.
- Your credit is under 700.
- Your DTI is stretched, since the interest-only payment on the full line counts.
- The property is vested in an LLC and you do not want to retitle.
- You need a fixed payment, since this line floats and does not convert.
Your rental is also the collateral. Experian notes that default on an investment property line can lead to foreclosure. Draw only what the property’s income and your own cash flow can carry.
How to Shop and Apply, Step by Step
1. Pull your payoff. Get the balance from your first mortgage statement and list any other liens.
2. Run the combined math. Subtract all liens from 70% of your estimated value.
3. Check your first mortgage documents for limits on added liens.
4. Confirm title. You or your revocable trust, not an LLC.
5. Check your credit against the 700 floor, and your DTI against the 50% ceiling.
6. Confirm the property type is eligible.
7. Go through a broker. A broker shops several wholesale lenders and matches the file to a program that fits.
Questions to ask any lender: Do you write second position on non-owner-occupied property? Do you size on the limit or the drawn amount? How do you value the property? Do you allow trust title? What happens to the payment when the draw period ends?
Lendmire’s piece How to Qualify for an Investment Property HELOC When You Want to Keep Your First Mortgage walks through that scenario in more detail.
Key Terms Defined
HELOC: A revolving line of credit secured by property equity that you draw from, repay, and draw from again.
Second lien: A loan recorded behind your first mortgage, paid second if the property is sold or foreclosed. The CFPB describes a HELOC behind an existing mortgage this way.
CLTV: Combined loan-to-value, meaning all loans secured by the property divided by its value.
Draw period: The early years when you borrow and pay interest only. Repayment follows, and the line amortizes.
DTI: Debt-to-income ratio, your monthly debt payments compared to your monthly income.
DSCR: Debt service coverage ratio, meaning rent divided by the full monthly payment on the property.
Frequently Asked Questions
Can I get a HELOC on a rental that already has a mortgage?
Yes, though few lenders write it. On Lendmire’s network an investment line sits in second position behind your first mortgage. It requires a 700 minimum credit score, a 70% combined cap, and individual or revocable trust title. Lender appetite varies, and every file is reviewed individually.
Does a HELOC replace my first mortgage?
No. It is a separate second lien. Your first mortgage keeps its balance, term, and payment. A cash-out refinance is what replaces the first loan. If you hold a low-cost first mortgage, a second line may fit. If your personal file is stretched, a replacement loan may work better.
Can an LLC-owned rental get this line?
No. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. A property already in an LLC needs a vesting change or a different structure, such as a DSCR cash-out, which can be available to LLC-titled rentals subject to program terms.
Does the rent matter for approval?
Not the way it does on a DSCR loan. These lines are personal-qualification products reviewed on credit, DTI, and equity, with rental history sometimes requested as supporting documentation. DSCR financing qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Will the HELOC payment stay the same?
No. The price floats through the 5-year draw and the 25-year repayment, and it never converts to fixed. At least 75% of the line is drawn at closing, so budget for interest-only payments that later become amortizing payments.
