The Quick Read: The lenders worth shopping are the ones willing to sit in second position behind your first mortgage, and which of them fit depends on whether the home is your residence or a rental, your credit, your combined loan-to-value, and how the property is titled. Lendmire is a mortgage broker, so it matches the file to a wholesale lender instead of selling one product.
- Combined loan-to-value (CLTV) means every loan on the home added together, divided by its value. Only your first mortgage’s balance counts in that math. Its rate does not.
- On an investment property, the wholesale network’s ceiling is 70% CLTV, with a 700 minimum credit score and lines up to $500,000.
- On a primary residence, the ceiling reaches 90% CLTV only at a 720-or-better credit profile, with lines up to $500,000 at that tier.
- An LLC cannot hold title on these lines. The borrower or a revocable living trust must.
- Lendmire’s home equity line programs are offered in 16 full-service states, which is narrower than its DSCR footprint.
What Decides Which Providers Say Yes
No honest list of top providers exists, because the best program for your situation depends on the home and on you. Lenders that write second-position lines vary by occupancy, credit, leverage, title, and property type. That is why this article explains the rules those lenders apply instead of ranking companies.
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 question gets narrow fast on a rental. NerdWallet says a line on an investment property is possible. It also says the lender pool is smaller than for a primary home, borrowing limits are lower, and rental lines can bring reserve requirements, proof of long-term tenants, and multiple appraisals. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
A broker changes the shopping problem. A single bank sees only its own guidelines. Lendmire places files across a multi-state network of wholesale HELOC lenders. It can steer a rental toward a program that allows second position and avoid programs that decline the file on sight.
How a HELOC Sits Behind Your First Mortgage
Your first mortgage stays exactly as it is. The line becomes a second lien, recorded behind it. If the first-mortgage lender is not repaid, it collects before the line does. A second-position lender prices that risk, which is why the rules tighten.
The line is revolving. You draw, repay, and draw again during a set period. The network’s lines use a draw period with interest-only payments, then a fully amortizing repayment period. Primary residences and second homes have two draw structures:
- A 3-year interest-only draw followed by a 17-year repayment.
- A 5-year interest-only draw followed by a 25-year repayment.
Investment lines use the 5-year structure only. At least 75% of the line is drawn at closing. Pricing floats during both the draw and repayment periods and never converts to fixed.
That 75% draw matters for sizing. You should not open a line expecting to leave most of it untouched. A line you will not use is the wrong fit.
How Underwriting Treats Your First Mortgage, Step by Step
Underwriting treats your first mortgage as a subtraction. It reduces the room you have, and nothing else. The steps run in the same order on almost every file.
1. Value. The lender sets the home’s value. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. A higher CLTV may call for a second valuation, and you can request a full appraisal at any size.
2. First-mortgage balance. The lender reads your mortgage statement or payoff figure. The balance is what counts. A low-rate first mortgage helps your cost of carry but creates no extra room.
3. CLTV cap. The lender applies a ceiling based on occupancy and credit tier. The full line counts toward CLTV, not just the amount drawn.
4. Line size. Maximum line equals value times the CLTV cap, minus every existing lien. The CFPB’s booklet describes the same method: lenders take a percentage of the appraised value and subtract what you owe.
5. Personal qualification. Unlike a DSCR loan, a HELOC qualifies the borrower. The lender reviews credit, housing history, and debt-to-income (DTI). In the network, maximum DTI is 50%, and 45% applies to credit profiles from 600 to 679. A ratio above 45% requires at least a 680 score.
6. Payment test. The lender qualifies you on the interest-only payment calculated on the maximum draw. It tests the line as if fully drawn, even if you plan to draw less.
7. Title review. The lender checks who holds title and whether the property type is eligible.
A worked example in percentages
Say a home is worth 100% of its value and your first mortgage balance is 45% of that value. On an investment property with a 70% CLTV ceiling, the room is 70% minus 45%, or 25% of value. On a primary residence for a borrower whose credit tier allows a 75% CLTV, the room is 75% minus 45%, or 30% of value. Higher tiers allow more, and the network’s 90% CLTV ceiling applies only at a 720-or-better credit profile.
A bigger first mortgage shrinks the line. A faster-paid-down first mortgage grows it. The first mortgage’s rate never appears in the calculation.
The line also has fixed limits. It runs from $25,000 up to $500,000 on an investment property, subject to lender guidelines and full file review.
Which Kind of Provider Fits Which Borrower
Provider types behave differently, even when no single company is named. This table describes fit, not terms.
| Provider type | Typically fits | Watch for |
|---|---|---|
| Large retail banks | Primary-home lines | Often first-position only on rentals |
| Credit unions | Members with long relationships | Property-count limits, local footprint |
| Online lenders | Simple, standard files | Narrow property and title rules |
| Your current servicer | Borrowers wanting one relationship | May not lend on rentals at all |
| Broker with wholesale network | Rentals, mixed occupancy, odd files | Availability by state, program fit |
The pattern behind the table is simple. Many retail lenders write lines on primary homes. Fewer write them on rentals, and fewer still do it in second position. In a BiggerPockets thread, investors describe being told that a bank would only lend in first position on a rental. That is anecdotal. It still matches a pattern many investors report.
Wholesale lenders in the network accept a standalone line in either first or second position. That is the practical edge of working with a broker.
Key Terms Defined
Combined loan-to-value (CLTV): the total of all loans against a home, including the full new line, divided by the home’s value.
Lien position: your lender’s place in line to be repaid. A first lien is paid first, and a second lien is paid after it.
Draw period: the stretch of years when you can borrow from the line and pay interest only.
Repayment period: the years after the draw ends, when the balance is paid down in full installments.
Vesting: how title is held, such as in your own name, a revocable living trust, or an LLC.
DSCR (debt service coverage ratio): property rent divided by the full monthly housing obligation. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Subordination: an agreement that keeps a line in second position when another loan is refinanced ahead of it.
Where the General Rule Breaks
The general rule is that your equity minus your first mortgage sets the line. These edge cases change the answer.
Title in an LLC. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. This is the sharpest structural difference from a DSCR loan. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead. Vesting changes can raise questions with your first-mortgage terms, title insurance, and liability planning, so speak with your attorney before retitling.
Property type. Eligible properties include single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not eligible.
Listing status. A handful of states bar a property listed for sale, or listed within the past 60 days. A rental you are about to sell is a poor candidate for a line.
Exposure limits. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the network’s higher-leverage program and $750,000 on its longer-runway program. A borrower with more than 15 financed properties is not eligible. Many credit unions set their own, lower property-count limits.
Credit history. Credit scores come from a single-bureau model keyed to the primary wage earner, and reports can be no more than 90 days old at closing. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history on an investment property follows a 7-year path for foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale. The 5-year-draw program also asks for two tradelines seasoned 12 months, or one seasoned 24, along with a clean housing history.
Freezes and reductions. Lenders can reduce or freeze a line if the home’s value falls, per the CFPB’s HELOC booklet. Do not count on a line as your only safety net.
Market figures versus the network. NerdWallet reports that lenders across the broader market commonly cap investment-property lines at 80% of value, with many going lower, versus 90% on a primary home. In Lendmire’s wholesale network, an investment-property line tops out at 70% CLTV. A primary residence reaches 90% CLTV only at 720 or better, up to $500,000.
The credit floor also moves with occupancy. The overall network floor is 600, and second homes start at 640. Investment property starts at 700.
First-Mortgage Scenarios
The first mortgage’s type and age change how the file reads, though not the CLTV formula.
A low-cost first mortgage. Keep it. A second lien lets you leave that loan untouched and borrow only what you need. The trade is a floating-price line and a smaller leverage ceiling than you would get on a primary home.
A recent purchase. Lenders value the home as it stands today, so a recent purchase price is not the only input. Seasoning rules differ by lender, so confirm them before you plan around a quick draw.
A government-backed first mortgage. Whether the first mortgage is conventional, FHA, or VA does not change the CLTV formula. It can change how a lender reads the first-mortgage terms, and it depends on the lender and the property.
A plan to refinance the first mortgage later. A new first-mortgage lender usually wants the line to stay behind it. That can require a subordination agreement, so ask the line’s lender early.
A plan to sell. The CFPB’s booklet says you generally must pay off the line in full when you sell. Budget for it at the closing table.
A debt-to-income squeeze. The new line adds an obligation on top of the first mortgage, and it is tested at the maximum draw. Rental income may be discounted or ignored by some lenders. An investor with heavy personal debt but strong rent coverage may fit better in a DSCR structure.
When a DSCR Cash-Out Refinance Fits Better
A DSCR cash-out refinance replaces your first mortgage instead of sitting behind it. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Read the complete DSCR loans guide for the full mechanics.
| Situation | HELOC behind first | DSCR cash-out |
|---|---|---|
| Low-cost first mortgage worth keeping | Fits | Replaces it |
| Property held in an LLC | Needs retitling | Fits, subject to program terms |
| Strong rent, heavy personal debt | May strain DTI | Reviewed on the property |
| Small equity need | Fits | Often more than needed |
| Interest-only, 5-year draw wanted | Built in | Select lenders offer interest-only |
On DSCR cash-out refinances, most of the network tops out around 75% LTV on standard rentals. Short-term-rental collateral is capped at 70% on a cash-out. About 6 months of seasoning is the common expectation. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Coverage of 1.00 is where select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Credit floors start at 620 in parts of the network, and most programs want around 660. A 700-plus score opens the strongest leverage tiers. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, and management sit outside the ratio.
Common Mistakes
- Assuming a great first-mortgage rate gets you a bigger line. Only the balance enters the CLTV math.
- Assuming any bank that lends on your home will lend on your rental. NerdWallet says not all lenders offer investment-property lines.
- Assuming rent sizes the line. On a HELOC, equity, credit, and DTI set the line. Rent is supporting evidence at most.
- Counting only the drawn balance. CLTV includes the full line limit.
- Opening a large line with no plan to draw it. At least 75% is drawn at closing.
- Starting a file with the property in an LLC. Fix the title question first.
Frequently Asked Questions
Can I get a HELOC on a home that already has a first mortgage?
Yes, if the lender writes second-position lines and your equity leaves room after the first mortgage. The first mortgage stays in place. The line’s size equals value times the CLTV cap, minus every existing lien. On an investment property, the network ceiling is 70% CLTV with a 700 minimum score.
Does a HELOC change or risk my first mortgage?
It does not change the first mortgage’s terms. It adds a second lien and an additional obligation. A drop in home value can lead a lender to reduce or freeze the line, and the first mortgage remains your priority payment.
Do I need my current mortgage lender to write the HELOC?
No. Asking your current servicer is a reasonable first step, but it is not required. Many retail lenders decline rentals or second-position lines. A broker can place the file with a wholesale lender whose guidelines fit the occupancy and the first mortgage.
What happens to the HELOC if I sell the home?
You generally must pay the line off in full when the home is sold, per the CFPB booklet. The balance comes out of the sale proceeds along with the first mortgage.
Can I get a HELOC if the rental sits in an LLC?
Not directly. LLCs cannot hold title on these lines. The property would need to move into your name or a revocable living trust, or you could look at a DSCR cash-out refinance, subject to program terms.
