The Quick Read: A landlord with a low first mortgage has real room to open an equity line on a rental, because the existing balance uses up less of a 70% combined loan-to-value ceiling. Approval still turns on you personally: credit of 700 or better, a debt-to-income ratio at or below 50%, and title in your own name or a revocable trust.
- On an investment property, the ceiling is 70% combined loan-to-value (CLTV). Credit above 700 does not raise it.
- Lines run from $25,000 to $500,000 and are subject to lender guidelines and full file review.
- An LLC cannot hold title on these lines. A rental already deeded to an LLC needs a vesting change or a different loan.
- At least 75% of the line is drawn at closing, so this is not a standby line you leave at zero.
- The lender underwrites you, not the rent. A landlord with many financed properties often fits a DSCR loan better.
What Is an Investment Property HELOC?
An investment property HELOC is a revolving line of credit secured by a rental you own. A HELOC is short for home equity line of credit. Equity is the property’s value minus what you owe on it.
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 line sits next to your first mortgage. It does not replace it. That is the whole appeal for a landlord who holds a mortgage they would hate to give up.
Lendmire brokers these lines through select wholesale partners, and Lendmire is never the lender. On this network, the line can sit in second position behind your first mortgage. It can also sit in first position on a property with no mortgage at all.
Not every lender writes these. NerdWallet’s guide to HELOCs on investment property says the lender pool is smaller and you typically borrow less than against a primary home. It also says lenders may require multiple appraisals and may restrict lines by location or by whether the home is rented all year.
Availability here is narrower than for DSCR loans. DSCR programs reach 41 markets, including Washington, D.C. The equity-line programs are limited to the 16 states where Lendmire is full-service.
What Are the Core Requirements?
The core requirements are 700 credit, 70% CLTV, a 50% debt-to-income limit, eligible property, and clean title. Those five items decide most files. Everything else is detail.
Here is how an investment line compares with a line on a primary residence on this network. Every figure is subject to lender guidelines.
| Factor | Investment property | Primary residence |
|---|---|---|
| Max CLTV | 70% | Up to 90% at 720+ |
| Minimum credit | 700 | 600 program floor |
| Line size | $25,000 to $500,000 | Up to $750,000 |
| Draw structure | 5-year draw, 25-year repayment | Two structures offered |
| Valuation | Automated valuation, usually | Full appraisal above $500,000 |
Two points deserve attention.
First, the investment table has two tiers. A 720 score and a 700 score both reach 70% CLTV. Extra credit buys you nothing on leverage, but 700 is a hard floor.
Second, NerdWallet lists at least 20% equity as a baseline for investment lines in the broader market. Do not plan around that. On Lendmire’s network, the investment ceiling is 70% CLTV, so plan on at least 30% equity.
Because the line tops out at $500,000, a full appraisal is not required. Most files use an automated valuation instead. You can still ask for a full appraisal.
How the line pays
Investment lines use one structure. You get a 5-year interest-only draw period, then a 25-year fully amortizing repayment period. Pricing floats during both periods and never converts to fixed. At least 75% of the line is drawn at closing.
The CFPB notes in its overview of home equity lines that draw periods can run as long as 10 years. Do not assume that applies to an investment line. Plan around the 5-year draw.
How Does a Low First Mortgage Change the Math?
A low first mortgage leaves more room under the CLTV ceiling. The formula is simple: property value times 70%, minus your first-mortgage balance. The result is your possible line, before the $500,000 maximum and $25,000 minimum apply.
The table below uses percentages of property value instead of dollars. Plug in your own numbers.
| First mortgage, % of value | Room under 70% CLTV | Read |
|---|---|---|
| 15% | 55% of value | Large room; the $500,000 cap may bind |
| 40% | 30% of value | Solid room |
| 60% | 10% of value | Thin; may miss the $25,000 minimum |
| 70% or more | None | No usable line |
Two limits matter at the edges. On a high-value rental, the $500,000 line cap binds before the CLTV ceiling does. On a modest rental with a mid-sized mortgage, the room can fall below the $25,000 minimum and the line disappears.
Now the catch. Because at least 75% of the line is drawn at closing, a big line means big borrowed money on day one. Size the line to a plan, not to the maximum.
A paid-off rental is the extreme case. With no first mortgage, the line can sit in first position and the full 70% CLTV is available, subject to the size limits.
“Low first mortgage” can also mean a low interest on that loan. A line leaves that loan alone. A cash-out refinance replaces it. Many landlords choose the line for exactly that reason.
How Is a Landlord Actually Underwritten?
A HELOC is underwritten on you. The lender looks at your credit, your debts, your income and your equity. The property’s rent plays a supporting role at most.
A DSCR loan works the other way. DSCR stands for debt service coverage ratio. It compares a property’s rent to its monthly payment, which includes principal, interest, taxes, insurance and any association dues. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
On the HELOC side, these are the main tests on this network:
- Credit: A 700 minimum on an investment property. The score comes from a single credit report keyed to the primary wage earner. The report can be no more than 90 days old at closing.
- Debt-to-income: A 50% maximum. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
- Housing history: Mortgage payment history is reviewed across all financed properties, not only the one you pledge.
- Derogatory events: A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history follows a 7-year path for a foreclosure and a 4-year path for a deed-in-lieu, pre-foreclosure or short sale.
This is why a landlord with many financed properties can fail a HELOC that a DSCR loan would handle. Every mortgage you carry lands in your personal debt-to-income ratio.
What Documents Should You Gather?
Expect a current first-mortgage statement, an insurance declaration, your vesting deed and credit and income documentation. Rental documents such as leases or Schedule E may be requested. What a lender wants varies by file and program.
Here is how the paperwork usually differs by landlord type:
- W-2 earner with one or two rentals: Pay documentation, the mortgage statement, the deed and the insurance page.
- Self-employed landlord: Income is reviewed on documented income under the applicable program, subject to lender guidelines. Business bank accounts need a 680 minimum for the deposit analysis. Investment already floors at 700, so that test is never the binding one.
- Multi-property landlord: Statements for every financed property, plus lease records. A borrower with more than 15 financed properties is not eligible.
The deed is the document that trips people up. Pull it first.
Where Do the Rules Break?
The rules break on title, property type, exposure limits and listing status. Each of these can end a file before credit is even reviewed.
LLC-held rentals. Title must sit with you individually or in 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. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead, subject to program terms.
Property types. Single-family homes, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial property, mixed-use property and agricultural zoning are not eligible.
Exposure caps. A borrower is limited to three lines. Across the two wholesale programs we place equity-line files with, combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. The caps matter to a landlord who wants to pull equity from several rentals.
Listed properties. In several of the states where Lendmire is full-service, a property listed for sale, or listed within the past 60 days, is ineligible.
Recent purchases. Seasoning rules depend on the program, valuation and title. It depends on the investor profile, the property and current lender guidelines. Ask before you assume a new purchase qualifies.
Short-term rentals. NerdWallet notes that some lenders restrict lines based on whether the home is rented all year. Short-term rental rules can vary by city, county, HOA and property type, so investors should confirm local rules before relying on projected rental income.
Primary-residence lines. Using the line on your own home to fund a rental is a different structure. The CFPB’s HELOC brochure warns that renting out your home may be prohibited under the terms of a line. Check your own agreement first.
Which Landlord Are You?
Match your situation to the right tool. This is a rough guide, not a ruling. Every file is reviewed individually.
| Your situation | Likely fit |
|---|---|
| Personal title, 700+ score, modest debts | Investment HELOC |
| Rental held in an LLC | DSCR cash-out refinance |
| Many financed properties, heavy debts | DSCR cash-out refinance |
| Need beyond a $500,000 line | DSCR cash-out refinance |
| Score under 700 | DSCR loan; most programs want about 660 |
| No wish to touch a cheap first loan | Investment HELOC |
For score ranges, the DSCR network has a 620 floor in parts of the network, most programs want around 660, and 700 or higher opens the strongest leverage tiers. The complete DSCR loans guide walks through those tiers.
Keep the First Mortgage or Replace It?
Keep it if the first mortgage is the best part of your balance sheet. Replace it if you need more cash than the line can give, or if title or credit blocks the line.
| Factor | Investment HELOC | DSCR cash-out refi |
|---|---|---|
| First mortgage | Stays in place | Replaced by new loan |
| Underwriting | You personally | Rent versus payment |
| Max leverage | 70% CLTV, investment property | About 75% LTV, standard rental |
| Payment shape | Interest-only draw, variable | 30-year fixed is the spine |
| Title | Individual or revocable trust | LLC possible, per program terms |
DSCR cash-out refinances typically want about 6 months of seasoning. Short-term rental collateral tops out at 70% on a cash-out. On a standard rental, the ceiling is about 75%.
DSCR coverage of 1.00 is where select programs start, and stronger ratios open better terms. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted. A ratio above 1.00 is not the same as positive cash flow. Repairs, vacancy, management and capital costs sit outside the calculation.
What Are the Risks, and What Is Your Exit Plan?
The main risks are variable pricing, a shrinking line and an unplanned payoff. Write the exit plan before you sign.
Pricing floats and never converts to fixed. When the interest-only draw ends, the payment shifts to full amortization over 25 years. A rental that cash-flowed during the draw can feel tighter after.
The CFPB brochure also says lenders can reduce the credit line if the home’s value drops. It says a HELOC may need to be paid off in full when you sell. A landlord planning a sale should assume the line must be cleared at closing.
Rent can drop too. Test your own numbers with a vacancy month or two built in.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.

How Does the Process Work?
The process runs in six steps. Keep them in this order.
1. Pull your deed and confirm how title is held.
2. Pull your first-mortgage statement and estimate property value.
3. Run the CLTV formula to see whether any room exists.
4. Check credit, debts and the listing status of the property.
5. Submit documents and let the lender review the file.
6. Review the draw requirement and your payoff plan before closing.
Key Terms Defined
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line and pay interest only.
Repayment period: The stretch after the draw ends, when you pay down principal and interest.
DSCR: A ratio that compares a rental’s income to its monthly debt payment.
Vesting: The way title is held, such as in your name, a revocable trust or an LLC.
Seasoning: The waiting period a lender wants before it counts an event, such as a purchase or a bankruptcy.
Frequently Asked Questions
Can I get a HELOC on a rental property at all?
Yes, through a limited set of lenders. On Lendmire’s network, an investment line requires 700 credit and caps at 70% CLTV. Lines range from $25,000 to $500,000, and approval remains subject to lender guidelines.
Does a low first mortgage let me borrow more?
It lets you borrow more relative to the 70% ceiling, up to the $500,000 line cap. A small balance leaves more room under the CLTV limit. It does not lift the ceiling itself, and credit above 700 does not raise it either.
Can my LLC own the property?
Not for this product. Title must be held by you individually or by a revocable living trust. A property in an LLC needs a vesting change, or a DSCR cash-out refinance, subject to program terms.
Do I need an appraisal?
Usually not. Lines at or below $500,000 ordinarily use automated valuation. A higher CLTV may call for a secondary valuation, and you may request a full appraisal in any case.
Is a HELOC the same thing as a DSCR loan?
No. A HELOC underwrites you: credit, debts and income. A DSCR loan reviews the property’s qualifying rent against its payment. That is why landlords with many financed properties often shift to DSCR.
