The Quick Read: A home equity line of credit (HELOC) lets a homeowner with a low-rate first mortgage borrow against equity without refinancing that loan. Which lender fits depends on occupancy, credit profile, combined leverage, and how the title is held. A broker that shops several wholesale HELOC lenders can match the file to the program that suits it.
- The ceiling depends on occupancy. An investment-property line tops out at 70% combined loan-to-value (CLTV), while primary-residence and second-home lines can reach 90% CLTV only at a 720 or better credit profile.
- The line is a second mortgage that sits behind your existing first mortgage and leaves it untouched.
- Pricing on this network never converts to fixed, so the payment can move.
- The title must sit in your own name or a revocable living trust. An LLC cannot hold it.
- A HELOC is a funding source, and a DSCR loan is the long-term financing for a rental. They work together rather than replace each other.
Why Locked-In Owners Reach for a Line
A homeowner who holds a low-rate first mortgage has a good reason to avoid replacing it. A HELOC leaves that loan alone and adds a separate line behind it. Only the new borrowing carries today’s pricing.
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.
CNBC reports on a Realtor.com analysis finding that 49.1% of outstanding mortgages carried a low enough first-lien rate to count as locked in. Those are the owners looking at equity lines instead of refinances.
Investors have a specific reason to care. Equity in a primary home or an existing rental can fund the down payment and reserves on the next purchase. The first mortgage stays in place while you do it.
How a HELOC Works, Step by Step
A HELOC is an open-end line of credit. The CFPB explains that you can draw up to your limit during a draw period, which could last 10 years, for example. After that, a repayment period begins and drawing stops. The FTC adds that you pay only on what you borrow, not on the full available line.
Here is how a lender treats the file:
1. The equity test. The lender applies a maximum CLTV to the property’s value. It then subtracts your first-mortgage balance. What remains is the most the line can be.
2. The valuation. On this network, lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher CLTV may call for a secondary valuation. A full appraisal is required on every line above $500,000, and you may request one in any case.
3. Credit. The score comes from a single-bureau model keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not allowed.
4. Debt-to-income. The ceiling is 50%. It drops to 45% for credit profiles from 600 to 679, and anything above 45% requires a 680 minimum. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
5. Property and title. The lender checks that the property type is eligible and that the title is vested correctly.
6. The draw, then repayment. Payments follow your balance during the draw. When repayment starts, you can no longer borrow, and the payment steps up as principal is added.
What Wholesale HELOC Lenders Look For
Lendmire is a mortgage broker, not a lender. It places HELOC files with select wholesale lenders, and the figures below are typical guidance subject to lender guidelines and full file review. Availability is limited to the 16 states where Lendmire offers full-service lending, which is narrower than its 41-market DSCR footprint.
| Occupancy | Minimum credit | Top CLTV | Maximum line |
|---|---|---|---|
| Primary residence | 600 | 90% (720+, up to $500,000) | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 640 | 90% (720+, up to $500,000) | $500,000 |
| Investment property | 700 | 70% | $500,000 |
The tiers step down as credit falls. On a primary residence, a 700 profile reaches 85% CLTV up to $500,000, and 640 reaches 80%. A 620 profile reaches 70% CLTV up to $400,000. On a second home, 640 reaches 75% CLTV.
A line above $500,000 is for primary residences only. It needs a credit profile of 700 or better (720 on the 5-year-draw structure described below). It caps at 75% CLTV and requires a full appraisal.
Market-wide figures run looser. NerdWallet reports that investment-property lines in the wider market can go to 80% LTV, though many lenders set lower limits. On this network, an investment line tops out at 70% CLTV.
Two Draw Structures
The network offers two standalone line structures. Each can sit in first or second lien position.
- The 3-year-draw structure pays interest only for 3 years, then fully amortizes over 17 years.
- The 5-year-draw structure pays interest only for 5 years, then fully amortizes over 25 years.
Investment lines run only the 5-year draw and 25-year repayment. Both structures require at least 75% of the line to be drawn at closing. That matters for a locked-in homeowner who wants a quiet standby cushion, because most of the line is borrowed on day one. Interest runs on that balance from the start.
After closing, the minimum subsequent draw is $1,000 under the 5-year-draw structure, with a higher minimum in Texas. The 3-year-draw structure does not state a subsequent-draw minimum. Any figure a lender quotes should come with its own program’s draw and repayment terms attached.
Where the General Rule Breaks
The headline ceilings are only the first gate. These are the situations where a file that looks fine on equity runs into something else.
LLC-held property. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot hold title on a HELOC. Only the individual borrower or a revocable living trust can. That is the sharpest structural difference from a DSCR loan, which can be made to an LLC subject to lender program eligibility. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead.
Renting out the house. Some line agreements restrict renting the home. A line on your primary residence is fine if you stay there. If you move out and rent the home, read the terms first, because the lender may treat that as a breach.
Property types. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums (including non-warrantable ones) are eligible. A 2-4 unit property needs a 640 minimum on the 5-year-draw structure. Modular factory-built homes are eligible on the 5-year-draw structure only. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible on either structure.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program. One structure declines it entirely, whatever its age. On primary residences and second homes, the other structure seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4. Investment files follow that 7-and-4 path. Housing-history standards also vary by program.
Sub-640 profiles. These are limited to single-family residences with a clean 12-month housing history under the 5-year-draw structure. Second homes floor at 640 and investment lines at 700, so this restriction reaches primary residences only.
Exposure and listing status. A borrower can hold at most three lines, with combined-exposure caps that differ by program. A borrower who owns more than 15 financed properties is not eligible. In some states, a property listed for sale within the past 60 days is ineligible, so confirm status before applying.
Tax questions. 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.
HELOC or Cash-Out Refinance?
The decision rule is simple. Bankrate says a HELOC leaves the first mortgage untouched, while a cash-out refinance replaces it. A HELOC fits when your existing rate sits well below today’s market. A cash-out refinance can make sense when your rate is at or above it.
For a rental, a cash-out refinance works differently from a HELOC. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. It also replaces your existing first lien.
Here are the structural differences:
| Factor | HELOC | DSCR cash-out refinance |
|---|---|---|
| Lien position | Adds a lien behind your first | Replaces the first lien |
| Existing first mortgage | Stays in place | Paid off |
| Typical top leverage | 70% CLTV on an investment property | Around 75% LTV across most of the network |
| Underwriting basis | Credit, DTI, equity | Rental coverage, credit, equity |
| Title | Individual or revocable trust | LLC allowed, subject to program terms |
Cash-out on a rental typically expects about 6 months of seasoning. 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 is not the same as positive cash flow, because repairs, vacancy, management, and utilities sit outside the calculation. The complete DSCR loans guide walks through the full mechanics.
A percentage-only example
Take an investment property with a first mortgage equal to 55% of its value. At the 70% CLTV ceiling, the line could reach 15% of value, subject to the $500,000 cap. Now take a primary residence with a first mortgage equal to 60% of value and a borrower at 720 or better. A 90% CLTV ceiling would leave up to 30% of value, again subject to the $500,000 cap for that tier. That is a lot more room, but it only applies to a home you live in. The calculator can turn these percentages into dollars for your property.
Stress-Testing a Floating Payment
A variable payment is the main risk on a HELOC. Run this test before you apply:
1. Take the full line, not the amount you plan to draw. The lender reviews your file on the maximum draw, so you should too.
2. Imagine the pricing stepping up. Then check whether the interest-only payment on that line still fits your budget.
3. Check the repayment cliff. When the draw ends, the line converts to principal-plus-interest amortization over 17 or 25 years, and the payment jumps.
4. If the money buys a rental, ask what happens if that property sits vacant. The HELOC payment is still due.
That last point is where a locked-in investor can get hurt. A vacant rental produces no coverage, and the line behind your first mortgage keeps billing. Reserves and a margin of safety matter more than the headline ceiling.
If you plan to put HELOC money into the down payment on a DSCR purchase, the extra debt shows up in your credit profile and in the lender’s reserve review. Treat the HELOC draw as borrowed money when you size reserves.
How a Broker Finds the Right Fit
Lender categories matter less than how each one treats your file. Large retail lenders, credit unions, and online lenders each tend to have a different appetite. Many offer lines only on primary residences, and not all lenders will write a line on an investment property at all. Wholesale HELOC lenders differ from each other in credit tiers, property rules, derogatory-event seasoning, and draw structure.
That is the case for working through a broker. Lendmire shops multiple wholesale lenders and matches the scenario to a program, rather than pushing one product. Which lenders fit depends on the property, the credit profile, the leverage you need, and the title.
Before you apply, prepare these:
- Your current first-mortgage balance and a realistic value estimate
- Credit profile and housing history on all financed properties
- Title documents showing whether you or a trust holds the property
- A clear purpose for the funds, whether a down payment, reserves, or renovation
- A list of every financed property you own
When comparing quotes, ask whether there are annual, inactivity, or early-closure fees. Ask how much must be drawn at closing, what the minimum subsequent draw is, and when the draw period ends. Lenders must disclose the charges to open, use, and maintain the account.
Key Terms Defined
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the home’s value.
Draw period: The stretch when you can borrow from the line, usually with interest-only payments.
Repayment period: The stretch after the draw ends, when you repay principal and interest and can no longer borrow.
Lien position: Where a loan stands in line to be repaid if the home is sold or foreclosed. A first lien is paid before a second.
Vesting: The legal form in which the title is held, such as in your own name or a revocable trust.
DSCR (debt service coverage ratio): Monthly rent divided by the full monthly payment, including principal, interest, taxes, insurance, and any HOA dues.
Frequently Asked Questions
Can I get a HELOC on a rental property without touching my first mortgage?
Often yes, but the rules are tighter. On this network, an investment-property line needs at least a 700 credit profile and tops out at 70% CLTV, with a $500,000 maximum line. Not all lenders offer lines on investment properties at all, as NerdWallet notes. Your existing first mortgage stays in place.
Can an LLC take out a HELOC?
No. The title must be held by an individual borrower or a revocable living trust. If your rental sits in an LLC, you would need to change the vesting or consider a DSCR cash-out refinance instead, subject to lender program eligibility.
Is a HELOC a fixed-payment loan?
No. It is revolving credit, and payments move with your balance. On this network, pricing floats through both the draw and repayment periods and never converts to fixed. If you want predictability, a lump-sum structure or a refinance may suit you better.
How much of the line do I have to borrow?
At least 75% of the line must be drawn at closing on both structures. That makes it a poor fit for someone who wants a mostly unused standby line. Size the line to what you will actually use.
Does a HELOC replace a DSCR loan for buying a rental?
No. A HELOC is a funding source for a down payment or reserves, and a DSCR loan is the long-term financing for the rental. Many investors use one to help fund the other.
