The Quick Read: The providers that write a home equity line behind a fixed first mortgage on a rental are a small group, and the right one depends on your title, credit, equity, and how many properties you finance. Lendmire is a mortgage broker, so it does not rank companies. It shows you how these lenders underwrite and matches the file to a program.
- The line sits as a second lien behind your first. The fixed first stays exactly as it is.
- On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit score.
- Investment lines run up to $500,000 and are usually valued by automated valuation.
- Title must be in your own name or a revocable living trust. LLCs cannot hold title.
- The line floats. It never converts to fixed.
Why “Top Providers” Is the Wrong Question
Most lenders do not offer this product at all. A BiggerPockets thread reports that most lenders require first lien position on investment properties. That is the core problem for you, because you want to keep your first loan.
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.
So a ranked list would mislead you. The lender that fits depends on your credit profile, your title, your combined leverage, and how many loans you carry. A broker that shops several wholesale HELOC lenders can match the scenario to the program, which beats guessing which bank might say yes.
Key Terms Defined
Second lien: a loan recorded behind your first mortgage. The first lender gets paid first if the property sells or is foreclosed.
CLTV (combined loan-to-value): all loans on the property added together, divided by its value.
Draw period: the stretch when you can borrow from the line, usually paying interest only.
Repayment period: the stretch after the draw ends, when you pay principal and interest.
Vesting: how the property’s title is held, such as in your name, a trust, or an LLC.
How Underwriting Treats a Rental Line, Step by Step
Here is the sequence a lender follows on a line behind your first.
1. Lien position. The line records behind the first. Your first loan keeps its fixed rate, balance, and term. Its existing rate does not help or hurt the new line’s math.
2. Usable equity. The lender takes value times its CLTV cap, then subtracts the first loan balance. On an investment property in this network, the ceiling is 70% CLTV. Whatever is left is your possible line.
3. Personal profile. Unlike a DSCR loan, this is a personal-credit product. The lender looks at your credit score, your debt-to-income ratio (DTI), and the loans you already carry. DSCR loans qualify primarily on property-level rental income covering the payment, subject to lender guidelines. A line does not work that way.
4. Valuation. Because an investment line caps at $500,000, it normally runs on an automated valuation with no traditional appraisal. A higher CLTV may trigger a secondary valuation, and you can always request a full appraisal.
5. Draw and repayment. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing.
The federal consumer-finance regulator explains that HELOCs usually carry a variable rate, so payments can change month to month. Here the pricing floats across both the draw and repayment periods and never converts to fixed.
What Lenders Look For on This Network
These are typical ranges from select wholesale lenders, subject to lender guidelines and full file review.
| Factor | Investment property line |
|---|---|
| Max CLTV | 70% |
| Minimum credit | 700 |
| Line size | $25,000 to $500,000 |
| DTI | 50% maximum |
| Valuation | Usually automated |
| Title | Individual or revocable trust |
Two details matter. First, 720 and 700 both reach 70% CLTV, so a higher score buys eligibility rather than more leverage. Second, 700 is a hard floor with no tier beneath it.
DTI is figured on the interest-only payment calculated on the maximum draw. Credit reports must be no more than 90 days old at closing.
A Worked Example in Percentages
Picture a rental valued at a round figure with a first mortgage at 50% of value. At a 70% CLTV ceiling, about 20% of value is left for a line. Move the first mortgage to 60% of value and only about 10% remains. Once the first mortgage reaches 70% of value, nothing is left.
The takeaway is simple. A fixed first with a low balance leaves room. A fresh, high-leverage first leaves almost none. The calculator can show an illustrative estimate once you enter your own figures.
Size is a separate limit from equity, and it applies even when equity is plentiful.
Provider Types Compared
You cannot rank companies, but you can compare provider types by how they behave.
| Provider type | Lends behind a first? | Title flexibility | Typical friction |
|---|---|---|---|
| Lender holding your first | Sometimes | Varies by lender | Often declines rentals |
| Large retail lenders | Often not | Varies by lender | Owner-occupied focus |
| Credit unions, community banks | Sometimes | Varies by lender | Local limits on property count |
| Broker with wholesale network | Yes, on eligible files | Individual or revocable trust only | Narrow state footprint |
The BiggerPockets discussion describes the product as not super common, with smaller credit unions and banks as the usual sources. A broker’s advantage is reach. One application can be matched against several lenders’ guidelines instead of one institution’s appetite.
Availability here is narrower than the DSCR footprint. Lendmire’s HELOC placements run in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA.
Where the General Rule Breaks
LLC title. This is the sharpest difference from a DSCR loan. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. Individual names and revocable living trusts can. If the rental already sits in an LLC, you need a vesting change or a DSCR cash-out instead. Moving title can have its own consequences under your first mortgage, so read that loan’s documents first.
Your first mortgage’s terms. The note must allow a junior lien. Check for additional-lien clauses and any prepayment terms before you apply.
Portfolio size. A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible. Combined exposure across those lines is also capped, at $2,000,000 under the higher-leverage program and $750,000 under the longer-runway program. Your loan officer can tell you which program a given file falls under.
Property type. Single-family, 2-4 units, PUD, townhome, and condominium (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
Listed properties. A property listed for sale, or within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure follows a 7-year seasoning path, and a deed-in-lieu, pre-foreclosure, or short sale follows 4 years.
Keep the Fixed First or Replace It?
The main reason to choose a line is that you protect a low fixed first. The cost is a second payment, a second lien, and a floating rate. Both loans are secured by the same rental, so total debt service moves with the index. The CFPB booklet tells borrowers to compare draw periods, repayment periods, and rate caps, and to get three estimates.
| Choice | Keeps your first? | Reviewed on | Watch for |
|---|---|---|---|
| HELOC behind the first | Yes | Personal credit, DTI, equity | Floating payment, 70% CLTV cap |
| DSCR cash-out refinance | No, replaces it | Rental income coverage | Losing the old fixed loan |
A DSCR cash-out replaces the first loan, but it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. On most files it tops out around 75% LTV, with about 6 months of seasoning commonly expected. Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
Clearing 1.00 does not mean positive cash flow. The ratio compares rent to the full payment only. Repairs, vacancy, management, and capex sit outside it.
If you have a lot of financed properties or a tight DTI, the line route may close, and a rent-qualified DSCR loan can be more workable. You can read Lendmire’s guide for a first-time landlord with one rental for the single-property version of this question. The full structure of DSCR loans is in the complete DSCR loans guide.
Before You Apply: A Checklist
- Pull your first mortgage note and check for additional-lien and prepayment language.
- Confirm title is in your name or a revocable trust.
- Estimate value, subtract your first balance, and test it against 70% CLTV.
- Check that your credit score is 700 or above on a report under 90 days old.
- Total your DTI, counting the line’s interest-only payment on the maximum draw.
- Count your financed properties against the 15-property limit.
Common Reasons Files Get Stuck
| Issue | Fix |
|---|---|
| Credit under 700 | Build the score, or consider a DSCR cash-out |
| Combined leverage over 70% | Wait for paydown or appreciation |
| LLC title | Vest personally or use a DSCR cash-out |
| Rental is listed for sale | Wait out the 60-day window in affected states |
| Property is a manufactured home | Not offered; no workaround within these programs |
| State is outside the 16-state footprint | Look at DSCR options instead |
Frequently Asked Questions
Can I get a HELOC on a rental that still has a mortgage?
Yes, on eligible files. The line records as a second lien and leaves your first untouched. On this network, an investment line requires a 700 credit score, caps at 70% CLTV, and runs to $500,000, subject to lender guidelines.
Do I need a new appraisal?
Usually not. Investment lines sit at or below $500,000, so they ordinarily run automated valuation. A higher CLTV may call for a secondary valuation, and you may request a full appraisal at any time.
Can my LLC take out the line?
No. LLCs cannot hold title on these lines. Individuals and revocable living trusts can. If your property is already in an LLC, a DSCR cash-out may fit better, subject to program terms.
Is the rate fixed after the draw period?
No. Pricing floats during both the draw and the repayment period and never converts to fixed. The investment structure is a 5-year interest-only draw, then 25 years of amortizing repayment.
Can rental income qualify me?
Not the way it does on a DSCR loan. A line is a personal-profile product reviewed on credit, DTI, and equity. For a rent-driven file, look at a DSCR program instead.
