The Quick Read: A home equity line of credit (HELOC) on a rental is a separate loan that sits behind your first mortgage, so the first loan keeps its balance, term and payment, but only a narrow set of lenders write it on investment property, and the ones that do cap leverage at 70% combined loan-to-value. Lendmire is a mortgage broker, so it does not lend; it shops a network of wholesale lenders and matches the property to the program. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
- On an investment property, the network’s ceiling is 70% combined loan-to-value, with a 700 minimum credit score and lines up to $500,000, subject to lender guidelines.
- On a primary residence, the ceiling reaches 90% only at a 720-or-better credit profile, and on a second home it follows a similar tiered table.
- At least 75% of the line is drawn at closing, so this works like a loan you repay, not a standby card.
- LLCs cannot hold title on these lines, which is the sharpest difference from a DSCR loan.
- If no lender will open a line on the rental, a DSCR cash-out refinance is the other path, though it swaps out the loan you wanted to keep.
What “Without Touching Your First Mortgage” Really Means
A HELOC on a rental leaves your first mortgage exactly as it is. The balance, the term and the monthly payment on that loan do not change. The new line is a second loan that sits behind it. If the rental has no mortgage at all, the line can sit in first position instead.
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 the whole appeal for a short-term need. A cash-out refinance replaces your first mortgage and puts new terms on the entire balance. A line only prices the money you actually borrow. If your first mortgage has terms you would hate to give up, a small, temporary draw on a second loan can cost less overall.
“Without touching” has limits, though. The first loan stays intact, but it still shows up in the new lender’s math.
| Item | Does it change? | Why it still matters |
|---|---|---|
| First mortgage balance | No | Counts toward combined leverage |
| First mortgage payment | No | Counts in your debt ratio |
| First mortgage terms | No | The new line carries its own terms |
| Lien position | No | The new line sits behind it |
Picture the first mortgage as a tenant who never moves out. The new lender still counts that tenant when it measures how much room is left in the building.
Key Terms Defined
HELOC: a revolving line of credit secured by property equity, where you borrow against a limit during a set draw period.
Equity: what the property is worth minus what you owe on it.
Lien: a lender’s legal claim on a property until the loan is repaid. A second lien sits behind the first.
Combined loan-to-value (CLTV): all loans on the property added together, divided by the property’s value.
Draw period: the stretch when you can borrow from the line and, on these programs, pay interest only.
Repayment period: the stretch after the draw ends, when the balance fully amortizes, meaning each payment includes principal.
DTI (debt-to-income ratio): your monthly debt payments divided by your monthly income.
Subordination: a lender agreeing to stay in second position behind a new or changed first mortgage.
DSCR: debt service coverage ratio, which compares a property’s rent to its full monthly housing obligation.
Which Banks Offer This?
Few do, and the supply is concentrated in the wholesale channel. A rental HELOC is a second claim on a property the owner does not live in. Many large retail lenders decided years ago that they would not take that risk.
You can see it in how investors describe their calls. One investor on a BiggerPockets thread reported that a bank said it did not offer HELOCs on investment properties but would offer a cash-out refinance. That is a different product, and it replaces your first mortgage.
A practical tip from another BiggerPockets discussion: some lenders will not use the word HELOC for a rental but offer something similar. Ask for a line of credit secured by investment property. Ask whether the product exists for non-owner-occupied property before you ask whether you qualify.
Here is how the lender types sort out in practice:
- Large retail banks: mostly focused on lines against a home you live in.
- Local banks and credit unions: a smaller group still writes rental lines, often with conservative leverage caps and portfolio-style guidelines.
- Wholesale lenders reached through a broker: these write equity lines on investment property under set guidelines, and a broker can compare several at once.
This is where a broker earns its keep. Lendmire works with select wholesale HELOC partners. The best program for your situation depends on the property type, your credit profile, how much leverage you need and how you hold title. Availability is the first question to settle, because the HELOC footprint is narrower than Lendmire’s 41-market DSCR footprint.
How Underwriting Treats a Rental HELOC, Step by Step
A rental HELOC is underwritten mostly on you, not on the property’s rent. The lender looks at your credit, your debt ratio and the equity in the home. Here is the sequence.
Step 1: Pick the collateral. The line can sit on the rental itself, in second position behind the mortgage you keep. Or it can sit on your own home. A line on your residence often has stronger economics, but it puts the roof over your head behind the investment.
Step 2: Check title and vesting. The property must be held by you as an individual or by your revocable living trust. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title on these lines. If the rental is already deeded to an LLC, you need a vesting change first. Another option is a DSCR cash-out refinance, which can work with LLC-titled properties subject to program eligibility.
Step 3: Run the combined leverage test. The lender adds your first mortgage and the new line, then divides by the property’s value. The result must sit under the program’s ceiling for your occupancy type.
Step 4: Value the property. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal, though a higher CLTV can trigger a second valuation. You can also request a full appraisal. That matters if you recently renovated, because an automated model may not capture the improvement. A banker on BiggerPockets makes the same point about automated appraisals on rehabbed properties.
Step 5: Review credit and debt ratio. The lender uses a single-bureau credit score keyed to the primary wage earner. The maximum debt ratio is 50%, and a ratio above 45% requires at least a 680 score. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. Plan around that.
Step 6: Gather documents. Expect ID, income documentation, a lease and the statement for your first mortgage. Credit history matters too: a bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure or short sale needs 4.
Step 7: Close and draw. At least 75% of the line is drawn at closing. After that, a minimum subsequent draw of $1,000 generally applies on the program that states one.
The Numbers by Occupancy
Leverage on an equity line depends on how the property is used, and the investment ceiling is the lowest. These figures come from select lenders in Lendmire’s wholesale network and are subject to lender guidelines and full file review.
| Occupancy | Minimum credit | Top CLTV ceiling | Largest line |
|---|---|---|---|
| Investment property | 700 | 70% | $500,000 |
| Second home | 640 | 90% at 720+ | $500,000 |
| Primary residence | 600 | 90% at 720+ | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
Two cautions apply. First, the 90% figure exists only at a 720-or-better credit profile and only up to $500,000. Lower scores step down through lower ceilings. Second, a line above $500,000 is for primary residences only. It requires a score of 700 or better (720 on the longer-runway structure described below), caps at 75% CLTV and requires a full appraisal.
One BiggerPockets thread reported a banker saying only one or two lenders offered an investment-property line at 60% to 65% LTV. That is anecdotal and dated. The network figure for an investment property is 70% CLTV. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Property type matters as well. Eligible properties include single-family homes, 2-4 unit buildings, PUDs, townhomes and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not offered. In several of the 16 states, a property listed for sale within the past 60 days is also ineligible.
Structures and Variations
The spine of this product is a standalone line in first or second position, but the draw structure varies. Primary residences and second homes offer two choices:
- Shorter-draw structure: a 3-year interest-only draw, then a 17-year fully amortizing repayment.
- Longer-runway structure: a 5-year interest-only draw, then a 25-year fully amortizing repayment.
Investment lines run only the 5-year draw and 25-year repayment structure. On both programs, pricing floats through the draw and repayment and never converts to fixed. When someone quotes you a figure, ask which structure it belongs to.
That draw-then-repay shape is normal for lines. The CFPB describes an example with a draw period that could last 10 years, followed by repayment over often ten or 20 years. It warns that payments often rise significantly when repayment begins and that some plans demand the whole balance at that point. Interest-only does not mean cheap, and it does not mean safe.
Other structures sit nearby:
- Closed-end second loan: a one-time lump sum that you cannot re-borrow. A BiggerPockets reply notes these exist on investment properties. Availability and terms vary by lender.
- Line on your own home: a different, owner-occupied product with its own ceiling table, and it moves rental risk onto your residence.
- DSCR cash-out refinance: replaces the first mortgage and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Where the General Rule Breaks
The idea that a line suits any short-term need has real exceptions.
The 75% draw at closing. If you only need a small amount for a few months, a line that requires most of its limit drawn on day one may be larger than you want. You can size the line to your need, but the line has a $25,000 minimum, so a very small need may not fit.
LLC-held rentals. Many investors hold rentals in an LLC for liability reasons. These lines cannot be written to an LLC. You would need to move title into your name or a revocable trust, which has its own consequences, or look at a business-purpose DSCR cash-out instead.
Freezes and limit cuts. A line is not guaranteed funding. The Consumer Compliance Outlook, a Philadelphia Fed publication, explains that lenders may freeze or reduce a line only under specified circumstances. One is a significant drop in value, which official commentary treats as met if the gap between your limit and available equity shrinks by 50 percent. A second is a default on a material obligation. If the rental’s value slides, the unused part of your line can disappear.
Selling or refinancing the first mortgage mid-draw. A new first mortgage generally requires the line lender to agree to stay in second position. That is subordination, and the lender has to approve it. Ask about it before you sign, not when you refinance.
Exposure limits. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible. Portfolio investors should check this early.
Thin credit history. The investment ceiling comes with a 700 minimum. Below that, an investment property is not offered on this line, even if the equity is there.
Equity is not the only test. More equity does not erase the credit floor, the debt-ratio limit or the property eligibility rules. The strongest files clear both tests: enough equity and enough personal borrowing capacity.
What the Decision Looks Like in Practice
Run the numbers on a rental where your first mortgage sits at 55% of the property’s value. On an investment property with a 70% CLTV ceiling, that leaves room for new borrowing of 15% of value. The line must be drawn at least 75% at closing, so you would draw roughly 11% of value on day one.
That is the trade. You keep the first mortgage’s terms, but you add a second payment that the rental must carry. A banker on BiggerPockets warns that a low-cost first mortgage plus an expensive second can cost more overall. The same banker describes the usual plan as using the line to buy or fund a project, then refinancing within a year or two to bring the cost back down.
Here is how the three common routes compare on a short-term need:
| Factor | Rental HELOC | Closed-end second | DSCR cash-out |
|---|---|---|---|
| First mortgage | Stays | Stays | Replaced |
| Money arrives as | Line, 75%+ drawn at closing | One lump sum | One lump sum |
| Qualifies mainly on | Personal credit and DTI | Varies by lender | Rental income vs payment |
| Title | Individual or revocable trust | Varies | LLC eligible per program terms |
| Leverage cap | 70% CLTV (investment) | Varies | Around 75% LTV on standard rentals |
The DSCR route has its own rules. Cash-out refinances on standard rentals top out around 75% loan-to-value across most of the network, with about 6 months of seasoning commonly expected. A 1.00 coverage ratio is where many select programs start, and 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 housing payment only, and repairs, vacancy and management sit outside it. For the full picture, see the complete DSCR loans guide.
The decision usually comes down to one question: how valuable is your current first mortgage? If it is valuable, a line keeps it. If it is not, replacing it may be worth the closing costs and open higher leverage on a rental that clears its coverage test.
Questions to Ask Before You Apply
- Does this lender write lines on non-owner-occupied property at all?
- Is the line a first or second position, and what is the maximum CLTV for my occupancy type?
- What portion must I draw at closing, and what is the minimum draw after that?
- Will the valuation be automated, and can I request a full appraisal?
- What happens to the payment when the draw period ends?
- Does the lender charge anything if I close the line early?
- Will the lender subordinate to a new first mortgage?
- Can the line be vested the way I hold the property?
If you ask a bank these questions and get blank stares, you have probably found a bank that does not write the product.
Frequently Asked Questions
Does a HELOC change the terms of my first mortgage?
No. A HELOC is a separate loan behind the first mortgage, so the balance, term and payment on the first loan stay as they were. The first mortgage still counts, though, in the combined leverage test and in your debt ratio.
Why do so many banks say they don’t offer a HELOC on a rental?
Many large retail lenders no longer write equity lines on non-owner-occupied property, so the answer is often a policy decision rather than a credit decision. A small group of banks and credit unions still do, and wholesale lenders reached through a broker offer it under set guidelines. Ask whether the product exists before applying.
What is the maximum leverage on a HELOC for an investment property?
Across select lenders in Lendmire’s network, the ceiling on an investment property is 70% combined loan-to-value with a 700 minimum credit score and a line up to $500,000. Primary residences and second homes follow different tables, reaching 90% only at a 720-or-better credit profile. Every figure is subject to lender guidelines and full file review.
Can I hold the rental in an LLC and still get this line?
Not on these lines. Title must sit with you individually or in a revocable living trust. A property already deeded to an LLC needs a vesting change, or a business-purpose DSCR cash-out refinance may fit instead, subject to program eligibility.
Is a HELOC a good idea if I only need money for a short time?
It can be, if your first mortgage is worth keeping and you have a clear plan to repay the line or refinance. The draw requirement at closing, the payment step-up after the draw period and the freeze triggers all matter. Size the line to the need and settle the exit before you close.
