The Quick Read: A rental HELOC typically is a second-lien line recorded behind your existing loan, so the first mortgage keeps its own balance, term and payment while the line pays for the remodel. On Lendmire’s wholesale network, an investment-property line caps at 70% combined loan-to-value, runs up to $500,000, and qualifies the borrower personally, not the rent.
- The first mortgage stays untouched because the line is a separate lien behind it.
- Investment lines require a 700 credit minimum and cap at 70% CLTV.
- The property must be titled to you or a revocable living trust, not an LLC.
- Rent does not size or qualify the line. Your credit, debt-to-income and equity do.
- The line must be repaid even if the remodel does not lift value as planned.
Most investors who ask this question have a low-balance first mortgage and a rental that needs work. They want the work paid for without giving up the first loan. That is a reasonable goal, and a rental HELOC can do it. It is also a narrow product with real limits. This piece walks through how it works, how the file is reviewed, where it breaks, and when a different tool fits better.
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.
What Is a Rental HELOC, Exactly?
A rental HELOC is a revolving line of credit secured by an investment property. Like any home equity line, it has a draw period followed by a repayment period. The CFPB explains that you cannot borrow after the draw period ends, that monthly payments are often significantly higher in repayment, and that most lines carry a variable rate.
Availability is the first hurdle. NerdWallet reports that a HELOC on an investment property is possible, but the lender pool is smaller, requirements are stricter, and borrowing limits sit below those on a primary home. That matches what a broker sees across the wholesale network. Few lenders write the product, and those that do apply tighter terms than they do on an owner-occupied home.
Key Terms Defined
HELOC: A revolving line of credit secured by property, with a draw period and a repayment period.
Second lien: A loan recorded behind the first mortgage, paid second if the property is sold or foreclosed.
CLTV (combined loan-to-value): All recorded loans, including the new line’s limit, divided by the property value.
Draw period: The stretch when you can borrow from the line, often paying interest only.
Vesting: How title is held, such as your own name or a revocable living trust.
DSCR loan: An investor loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
How Does the First Mortgage Stay Put?
The first mortgage stays because the HELOC does not replace it. The line is a separate loan recorded behind the first lien. The first lender’s balance, term and payment do not change. Only the first mortgage’s balance matters to the new lender, because it feeds the combined leverage math. Its interest rate does not.
On Lendmire’s network the line can sit in first or second lien position. For this use, you want second position behind the loan you are keeping.
| Item | First mortgage | Rental HELOC |
|---|---|---|
| Lien position | First | Second |
| What changes | Nothing | New line added |
| Balance | Stays as is | Drawn as needed |
| Who qualifies | Already done | You, personally |
Before you apply, read the existing mortgage documents for any restriction on added liens. Public sources do not settle whether a first lender must consent to a junior lien, so the loan documents are the place to check. Do not assume either way.
Is a Rental HELOC Available to You?
Eligibility turns on five things: occupancy, title, credit, debt-to-income and equity. Here is how the network treats an investment line.
- Credit: 700 is a hard floor, and both the 720 and 700 tiers reach the same 70% CLTV. Credit above 700 buys eligibility, not extra leverage.
- Leverage: The ceiling on an investment line is 70% CLTV, subject to lender guidelines.
- Line size: $25,000 to $750,000 across the products, but an investment line caps at $500,000. Anything larger is for primary residences only.
- Debt-to-income: 50% maximum, qualified on the interest-only payment calculated on the maximum draw.
- Exposure: A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible.
Market surveys paint a similar picture of strictness. NerdWallet reports typical market maximums of 80% LTV on investment properties, with many lenders below 70%. That is a market-wide figure. On this network, an investment line tops out at 70% CLTV.
Property type matters too. Single-family, 2-4 unit, PUD, townhome and condominium properties are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not offered.
Availability is also geographic. These lines are offered only in the 16 states where Lendmire operates as a full-service mortgage broker. That is narrower than the 41-market DSCR footprint, and it is worth confirming before you plan around a HELOC.
How Do You Size the Line to the Remodel?
You size the line with CLTV, not rent. Take the property’s value, multiply by the CLTV cap, and subtract every lien already recorded. What remains is the most the line can be. On an investment property, the cap is 70%.
Run it in percentages. Say a rental’s existing first mortgage uses 40% of the property’s value. At a 70% CLTV ceiling, about 30% of value is left for the line, before any dollar limits. Now say the first mortgage uses 62%. Only about 8% of value is left, and that is probably too thin for a real remodel.
The value used is the as-is value, not the after-remodel value. That is a point investors often miss. The work you plan to do does not count toward your borrowing room.
Add a contingency to the budget before you size anything. Remodels run over. If the line only covers the base scope, any overrun comes out of your cash.
A few sizing details specific to investment lines:
- Because the line caps at $500,000, it falls in the automated-valuation lane. Most investment lines close with no traditional appraisal, though a borrower can request a full one.
- At least 75% of the line is drawn at closing. That is a large number. Interest accrues on the drawn amount, so a line sized far above the remodel budget costs more to carry.
- After closing, the minimum subsequent draw is $1,000 under the longer-runway structure, described below.
That 75% initial draw changes how you should think about “borrow only what you use.” The line is not a card you leave idle. Most of it funds at closing.
What Does the Draw and Repayment Structure Look Like?
Investment lines run one structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats through both periods and never converts to fixed. Primary residences and second homes have a second option, a 3-year draw with a 17-year repayment, but that shorter structure does not apply to an investment property. (Tennessee shortens the timelines.)
The CFPB’s consumer materials flag the risks that come with this design. The CFPB brochure notes that some plans are interest-only during the draw, that variable-rate payments can change even if you borrow nothing more, and that lenders must disclose minimum draw requirements. In practice, the step-up when repayment begins is the point where thin deals break.
So plan the exit before you sign. There are three common exits:
1. Refinance. A DSCR cash-out refinance can pay off the line once the remodel has lifted value and the property has rental history.
2. Sale. Sell the property and pay off both liens from proceeds.
3. Paydown. Retire the line from cash flow over the draw period.
Whichever you choose, the line has to be repaid even if the appraisal after the work comes in light.
Step-by-Step Funding Sequence
Here is the order that keeps files clean.
1. Scope and bid the work. Get contractor bids and a contingency number first. The remodel budget drives everything else.
2. Check the first mortgage documents. Look for any restriction on added liens and get the exact payoff balance.
3. Confirm title. The property must be held by you individually or by an inter vivos revocable living trust. If it sits in an LLC, stop here and read the next section.
4. Calculate CLTV. Add the first mortgage balance to the line you want, divide by the as-is value, and compare against the 70% ceiling.
5. Check your personal file. Credit at 700 or better, a DTI at or under 50%, and a credit report no more than 90 days old at closing. Credit is a single-bureau score keyed to the primary wage earner, and there are no rescores.
6. Submit for valuation and review. Most investment lines use an automated valuation. A higher CLTV may require a secondary valuation.
7. Close and manage the initial draw. At least 75% of the line funds at closing. Move the funds into a dedicated account so remodel money stays separate from everything else.
8. Pay the contractor against milestones. Use the remaining line for later draws, each at least $1,000 under the longer-runway structure.
9. Execute the exit. Start the refinance or sale conversation before the draw period ends, not after.
Where the General Rule Breaks
LLC-titled rentals. This is the sharpest edge case. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title on a HELOC. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead. A DSCR cash-out replaces the first mortgage, so the old loan is gone. That defeats the goal of this article. Re-titling is a decision to make with your attorney, subject to the lender’s program terms and the first mortgage’s own documents.
High existing leverage. If the first mortgage already uses most of the 70% CLTV room, there is nothing left to borrow. The answer is a cash-out refinance, not a larger line.
Larger remodels. An investment line caps at $500,000. A line above that is primary-residence only, requires a 700 credit profile or better (720 on the longer-runway structure), caps at 75% CLTV, and needs a full appraisal. An investment property cannot use it.
Using a different property’s equity. Some investors borrow against the home they live in and spend the money on the rental. Primary-residence lines reach a higher ceiling, up to 90% CLTV, and that tier exists only at a credit profile of 720 or better. The trade-off is serious: your residence becomes the collateral for a rental project. Texas primary residences are a special case. They are homestead properties and cap at 80% combined loan-to-value.
Listed properties. A property listed for sale, or listed 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. Investment files follow a 7-year seasoning path for foreclosure and 4 years for a deed-in-lieu, pre-foreclosure or short sale.
HELOC, Cash-Out, or Something Else?
| Option | First mortgage | Reviewed on | Title | Best fit |
|---|---|---|---|---|
| Rental HELOC | Stays | Your credit and DTI | Individual or revocable trust | Low first loan, modest project |
| DSCR cash-out | Replaced | Property rent vs. payment | LLC allowed, subject to program terms | LLC-held or large project |
| Primary-home line | Stays | Your credit and DTI | Individual or trust | Ample equity at home |
| Cash | Stays | None | Any | Smaller scope |
The core contrast is the review basis. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A rental HELOC qualifies you. For a full look at how DSCR files are built, Lendmire’s complete DSCR loans guide covers the mechanics.
On cash-out, the leverage ceiling is different. A DSCR cash-out on a standard rental tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. That is a separate loan with a separate purpose. It replaces your first mortgage. If keeping that loan is the point, the line is the tool. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Cash-Flow Stress Test
The line does not show up in the first loan’s coverage, but it still draws on your cash. During the draw period the payment is interest-only on the drawn balance, which is mostly funded at closing. When repayment starts, payments are often significantly higher, per the CFPB.
Test three failure modes before you commit:
- Vacancy during the work. The unit may sit empty while you pay interest and the first mortgage with no rent coming in.
- Overruns. If costs exceed the line, the difference comes from reserves.
- A low post-remodel value. The line stays due whatever the appraisal says. An improvement may support a higher appraised value, depending on comps and underwriter review. It is not a guarantee.
Also remember what DSCR does and does not measure. Coverage compares rent to the full monthly payment on the loan, and nothing else. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, management and utilities sit outside the calculation. A later DSCR refinance will also have to account for the line, so it gets paid off or subordinated at that point.
The HELOC payment also counts toward your personal DTI. That matters if you plan to apply for another personal-income loan while the line is open.
Records and Taxes
Tax treatment varies by how the funds are used and how the property is held. Keep the remodel draws in a dedicated account, keep invoices tied to the project, and consult a qualified tax professional before relying on any deduction.
Common Mistakes
- Planning around an LLC-held property without checking title first.
- Sizing the line off the after-remodel value instead of the as-is value.
- Forgetting that 75% of the line funds at closing.
- Skipping the exit plan until the draw period is nearly over.
- Assuming rent qualifies the line.
- Applying outside the 16 states where the product is offered.

Frequently Asked Questions
Can I get a HELOC on a rental property and keep my first mortgage?
Yes, if you hold title individually or in a revocable living trust and meet the credit and equity tests. The line sits behind your first mortgage, which keeps its balance, term and payment. Investment lines on this network require a 700 credit minimum and cap at 70% CLTV.
Does the rent qualify me for the line?
No. Rental HELOCs qualify the borrower on credit, debt-to-income and equity. A DSCR loan is the product that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Can an LLC own the property?
Not for this product. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title on the line. A property already in an LLC needs a vesting change or a DSCR cash-out, and the cash-out replaces your first mortgage.
How much of the line do I draw at closing?
At least 75% on both draw structures. Pricing floats during the draw and repayment periods and never converts to fixed, so size the line close to the actual budget.
Will I need an appraisal?
Usually not on an investment line. Because it caps at $500,000, it normally runs an automated valuation, though a higher CLTV may require a secondary valuation and a borrower may request a full appraisal.
