The Quick Read: There is no single top provider, because the right one depends on your credit profile, your combined leverage, your property type, and how much you need. A HELOC (home equity line of credit) on a primary home with a mortgage already in place sits behind that mortgage as a second lien. Lendmire is a mortgage broker, not a lender. It shops a network of wholesale HELOC lenders and matches your file to the program that fits.
- The first mortgage stays untouched. The new line is recorded behind it.
- On a primary residence, the network’s ceiling reaches 90% CLTV, but only at a 720-or-better credit profile and a line up to $500,000.
- Lines run from $25,000 to $750,000, and the largest lines carry tighter rules.
- Your first-mortgage balance, credit, and debt-to-income ratio set the amount. Rent from other properties does not raise it.
- Every figure here is subject to lender guidelines and full file review. None of it is a commitment to lend.
Why Nobody Can Name One Winner
Any list that crowns a single best provider is guessing about your file. Lenders differ on credit floors, leverage caps, property types, valuation methods, and whether they write a second lien at all. A lender that fits a 760-score borrower with a condo may be wrong for a 650-score borrower with a duplex.
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.
That is why this page does not rank companies. It shows what these lenders look for and how their programs work, so you can see which kind of file you have. Brokers earn their place on this question. One broker can place the same file with several wholesale lenders and compare the terms side by side.
How a HELOC Works Behind an Existing Mortgage
You do not pay off your mortgage first. The CFPB explains that when you already have a mortgage, a HELOC counts as a second mortgage, paid on top of the first.
The line is open-end, meaning you can borrow, repay, and borrow again up to the limit. The CFPB’s HELOC explainer describes a draw period, then a repayment period when borrowing stops. Your home is the collateral, so a missed payment puts the home at risk.
The network’s lines come in two draw structures on primary residences:
- A 3-year interest-only draw, then a 17-year fully amortizing repayment.
- A 5-year interest-only draw, then a 25-year fully amortizing repayment.
Pricing floats through both the draw and the repayment period and never converts to fixed. A quote always belongs to its own structure, so compare them one at a time.
The Math: How Much Can You Borrow?
Lenders work from combined loan-to-value, or CLTV. That is your first-mortgage balance plus the full HELOC limit, divided by the home’s value. Experian’s CLTV explainer uses the same definition. The limit counts in full, not just what you draw.
The steps run like this:
1. The lender sets the home’s value, usually by automated valuation on lines of $500,000 or less. 2. It adds your first mortgage and any other recorded liens. 3. It applies its CLTV ceiling for your credit tier and subtracts the existing debt. 4. It checks your credit and debt-to-income ratio, including the first-mortgage payment.
Here is a run-the-numbers picture. Say your home is worth $500,000 and your first mortgage is $300,000. That is 60% of value already spoken for. At a 720+ credit profile, the network’s primary-residence ceiling is 90% CLTV on lines up to $500,000. That leaves room for a line equal to up to 30% of value, subject to the full review. At 660 or 680 the ceiling is 85%, which leaves up to 25%. At 620 the ceiling falls to 70%, which leaves up to 10%.
Same house, same mortgage, three very different lines. Credit does a lot of the work here.
Leverage by Credit Tier on a Primary Residence
These are network guideline ranges for a primary residence, subject to lender guidelines. They are not offers.
| Credit score | Max CLTV | Max line at that tier |
|---|---|---|
| 720+ | 90% | $500,000 |
| 700+ | 85% | $500,000 |
| 660-680+ | 85% | $500,000 |
| 640+ | 80% | $500,000 |
| 620+ | 70% | $400,000 |
| 600+ | 60% | $400,000 |
A 720+ borrower faces a tradeoff. You can take up to 90% CLTV on a line up to $500,000, or a larger line up to $750,000 at a reduced 75% CLTV. The $750,000 line opens at a 700-or-better credit profile (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal. It is for primary residences only.
For context, market surveys such as Achieve’s guide report that lenders across the broader market allow 80% to 90% of appraised value minus the existing mortgage. On this network, 90% exists only at a 720-or-better profile.
What These Lenders Look For
Credit. The program floor is 600. The score model is single-bureau, keyed to the primary wage earner, and the report must be no more than 90 days old at closing. Tradeline and housing-history standards vary by program.
Debt-to-income. The ceiling is 50%, or 45% for scores from 600 to 679. A ratio above 45% needs a 680 minimum. Lenders review your file on the interest-only payment calculated on the maximum draw, which is stricter than what you will pay in month one.
Valuation. Lines at or below $500,000 ordinarily use an automated valuation. A higher CLTV may require a secondary valuation. Every line above $500,000 needs a full appraisal, and you can request one anyway.
Property. Single-family homes, 2-4 units (640 minimum on the longer-runway structure), PUDs, townhomes, and condos, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural properties are not.
Title. You hold title personally or in a revocable living trust. An LLC cannot hold title on a HELOC, which is the sharpest difference from a DSCR loan.
Limits. A borrower can carry up to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. Owners of more than 15 financed properties are not eligible.
Credit events. A bankruptcy needs 4 years of seasoning. Foreclosure history splits by program: one seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4, and the other declines the history regardless of age.
Edge Cases Where the Standard Path Bends
An existing second lien. An older second mortgage or existing line counts in CLTV and shrinks your room dollar for dollar.
Refinancing the first mortgage later. This is the one that surprises people. When a new first lender pays off your old mortgage, your HELOC would otherwise jump into first position. New first-lien lenders will not close behind it. As FedLaws explains, the HELOC lender must sign a subordination agreement, and it can refuse. If you plan a later refinance, ask about subordination before you sign. The other routes are paying off the line first or rolling it into a cash-out refinance.
First-lien lines. If no mortgage is recorded, the line can sit in first position. That is a different product from a line behind a mortgage.
Business accounts. Using business bank statements for deposit analysis requires a 680 minimum. A 640 borrower can qualify for the line but cannot use business accounts.
Texas primary residences. A Texas primary is a homestead and caps at 80% combined loan-to-value, with a 12-day waiting period, a one-lien-at-a-time rule, and 12-month seasoning. Second homes and investment properties there follow their own tables.
New Mexico and Ohio. Both apply a CLTV cap that depends on the credit profile.
Listed properties. A home listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
Availability. Lendmire arranges HELOCs in its 16 full-service states only (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, WA). That is narrower than its DSCR footprint of 41 markets, including Washington, D.C.
Provider Types and Who Each Fits
You will see several kinds of providers. Each has a different strength.
| Provider type | Typical strength | Typical trade-off |
|---|---|---|
| Your current mortgage servicer | Familiar, one relationship | One program, one set of overlays |
| Big banks and credit unions | Existing deposit relationships | Narrower credit and property rules |
| Online lenders | Streamlined applications | Product menu varies widely |
| Broker with wholesale network | Many programs, one application | Each program has its own terms |
You are not required to use whoever holds your mortgage. Ask them for a quote, then compare it against others. A broker that shops multiple wholesale lenders can match your credit, leverage need, and property to the program that fits.
Using a Primary-Home Line for a Rental Purchase
Many investors ask this question, so here is the plain version. The home secures the debt, so a rental that underperforms puts your residence at risk. The CFPB warns that you could lose your home if you cannot repay.
A line also adds personal debt. A DSCR loan is sized on the rental’s income, so the HELOC payment does not enter that ratio. It does raise your total obligations, and the line is variable, with interest-only draws that convert to full repayment.
If you do pair a line with a DSCR purchase, plan the exit. Many DSCR loans carry prepayment terms that vary by program, which makes a quick refinance to repay the line costly. A larger down payment lowers the monthly payment and can lift coverage, though it never erases credit floors, reserve rules, or property eligibility. For the full picture, read the complete DSCR loans guide.
If your equity sits in a rental rather than your home, the options change. Investment lines on this network cap at 70% CLTV and run only the 5-year draw and 25-year repayment structure.
Key Terms Defined
- HELOC: a revolving line of credit secured by your home, with a draw period followed by repayment.
- Second lien: a loan recorded behind your first mortgage, paid second if the home is sold or foreclosed.
- CLTV: the first mortgage plus the full new line, divided by the home’s value.
- Subordination: the HELOC lender’s written agreement to stay in second position when the first mortgage is refinanced.
- DTI: your monthly debts divided by your monthly income.
- Interest-only draw: a period when payments cover interest only, before principal repayment starts.
What to Prepare Before You Apply
Gather your most recent mortgage statement, a current credit report, income documents, proof of homeowners insurance, and your title or vesting details. Know your estimated home value and your payoff balance. If you plan a refinance or sale soon, say so up front, because the full balance generally comes due when you sell.
Frequently Asked Questions
Can I get a HELOC while still paying my mortgage?
Yes. The line sits behind your mortgage as a second lien, and your first mortgage stays exactly as it is. The lender counts your first balance in CLTV and your first payment in DTI, and your credit tier sets the ceiling.
Do I have to use my current mortgage lender?
No. Your servicer is one option, not a requirement. Compare its quote against others, including a broker that shops several wholesale lenders, because each program has its own credit floors, leverage caps, and property rules.
Does rental income from my other properties raise my HELOC amount?
No. Your home’s value, existing debt, credit, and DTI set the amount. Rent does not raise the line. Rent matters on DSCR loans, which are underwritten to the property’s income instead.
What happens to my HELOC if I refinance my first mortgage later?
The new first-lien lender will require the HELOC to stay in second position. That takes a subordination agreement from the HELOC lender, which can refuse. The alternatives are paying off the line first or rolling it into a cash-out refinance.
Can an LLC hold a HELOC?
No. Title must be held by you personally or in a revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead.
