How an Investment Property HELOC Works to Refinance an Older HELOC Entering Repayment

The Quick Read: A new standalone line on the rental pays off the old balance at closing, and the old line is then closed and released. On the wholesale network Lendmire places files with, an investment-property line tops out at 70% CLTV and $500,000, with a 700 credit floor, subject to lender guidelines.

• The new line replaces the old one only when the old line is secured by the same rental, or when the proceeds are used to retire a line secured elsewhere.
• At least 75% of the line is drawn at closing, so the payoff comes straight out of that first draw.
• Pricing floats during the draw and the repayment period. The line never converts to fixed.
• Qualification leans on personal income, credit and combined leverage. Rent coverage is not the main test.
• An LLC cannot hold title on these lines. A property deeded to an LLC points toward a DSCR cash-out instead.

What Does an Investment Property HELOC Actually Do Here?

It gives the investor a fresh revolving line secured by a rental, and the first draw retires the older line. The older line stops being a problem because it no longer exists. The new line starts a new interest-only draw period instead of a payment jump.

NerdWallet notes that not every lender offers a line on an investment property, that the requirements are strict, and that multiple appraisals may be required. That matches what a broker sees across lenders. The product is rare, and the lenders that do offer it set tighter limits than they would on a primary home.

On the network Lendmire works with, the investment line is a standalone loan in first or second lien position. It runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Investment lines use that structure only. Lines are sized from $25,000 to $500,000 on a rental, and the combined ceiling is 70% CLTV.

Those limits sit well below some market figures. The network figure for an investment property is 70% CLTV, and that is the number to plan around.

This tool fits a specific investor. That investor owns the rental personally or in a revocable trust, has strong credit and income, and wants a revolving line again. It fits poorly when the property is in an LLC, when combined leverage already sits above 70%, or when the investor wants a fixed payment.

What Changes When the Old Line Enters Repayment?

The borrowing stops and the payment structure changes. Most draw-period payments are interest-only. Repayment adds principal, so the monthly obligation usually rises sharply.

The new line resets that clock. It does not remove the repayment cost, because the 25-year amortizing stretch still arrives after the 5-year draw. What the investor buys is time, plus a revolving line again.

How Does the Refinance Work Step by Step?

The sequence is the same on most files, and the order matters.

1. Pull the old agreement. Confirm the draw end date, the repayment term, any balloon language, any early-closure fee, and which property secures the line.

2. Get a payoff statement. The new lender needs the exact balance and the instructions for paying the old lender directly.

3. Check combined leverage. Add the first mortgage and the new line, then compare the total with the property value. On a rental, that total must fit within 70% CLTV.

4. Apply and document. The file includes a credit report, income documents, the mortgage statement, insurance, and title and vesting details.

5. Valuation. A line at or below $500,000 normally uses an automated valuation with no traditional appraisal. A higher CLTV may call for a secondary valuation. The borrower can also request a full appraisal.

6. Close and pay off. Title work confirms lien position. The new lender pays the old lender directly from the first draw.

7. Close and release the old line. Payoff and closure are separate steps. Ask the old lender to freeze the line and file a release, so no open line stays on title.

There are two structural variations. One is to refinance the first mortgage and keep the old HELOC in place. That only works if the HELOC holder agrees in writing to stay behind the new first lien. The other is to roll everything into a new first mortgage through a cash-out refinance, which leaves one loan and one payment.

Which Property Secures Your Old Line?

This question decides the whole plan, and most investors skip it. Only a loan secured by the rental can replace a line secured by the rental.

Many investors fund purchases with a line on their own home. If the old line sits on the home, a rental line does not swap into its place. A draw on the rental can provide cash to pay the home line off, but the lender reviews how proceeds are used and what the rental can support. A primary-residence line also carries different ceilings, reaching 90% CLTV only at a 720 or better credit profile. A rental never reaches that tier.

How Is the New Line Underwritten?

The new line is underwritten largely on the borrower, with the property as collateral. That is the sharpest difference from a DSCR loan, where rent against the payment carries the file.

For an investment line on this network, the main tests are:

• A credit score of at least 700. There is no tier beneath it. A score of 720 or better does not raise the investment ceiling above 70% CLTV.
• A maximum 50% debt-to-income ratio, qualified on the interest-only payment at the maximum draw.
• Title held by the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
• A property that is single-family, a 2-4 unit, PUD, townhome, or condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible.
• Exposure limits. A borrower can hold three lines, and an investor with more than 15 financed properties is not eligible.

Availability is also narrower than the DSCR footprint. Equity lines are available only in Lendmire’s 16 full-service states, while DSCR lending covers 41 markets, including Washington, D.C. Every figure above is subject to lender guidelines and full file review.

A Worked Example in Percentages

Run the combined-leverage math before anything else. Say a rental has a first mortgage equal to 40% of its value and an old HELOC balance equal to 20%. Combined leverage is 60%. A new line sized to retire the old balance keeps the total near 60%, which sits under the 70% CLTV ceiling with about 10 points of headroom. That file can work if credit, income and title also qualify.

Now change one input. The first mortgage is 55% of value and the old balance is 20%. Combined leverage is 75%, which is above 70%. The investor must pay the balance down, wait for appreciation, or move to a different structure. Lenders commonly count the full line amount toward combined leverage, so an unused portion does not help.

These are modeled percentages, not market data. The point is that the 70% ceiling, not the old balance, is usually the binding constraint.

When Does a DSCR Cash-Out Fit Better?

A DSCR cash-out fits better when the property is in an LLC, when income documents are messy, or when the investor holds many financed properties. It also fits when the investor wants a fixed structure rather than a floating line. The complete DSCR loans guide covers the mechanics. DSCR loans are designed for non-owner-occupied investment properties, and they qualify primarily on property-level rental income covering the payment, subject to lender guidelines.

On the DSCR side, 1.00 coverage is where select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. A cash-out usually expects about 6 months of seasoning, around a 660 credit score on most programs, and commonly about 6 months of PITIA in reserves, though these vary by lender.

Clearing 1.00 does not mean positive cash flow. The ratio compares rent with PITIA only. Repairs, vacancy, management, utilities and capex all sit outside it.

Where the General Rule Breaks

Several situations change the plan. Each deserves a check before the investor commits.

• Balloon lines. Experian notes that some HELOCs carry a balloon payment, meaning the whole balance is due when the draw ends. That turns the end date into a hard deadline, and it argues for acting before the date arrives.
• Payment shock. The CFPB’s HELOC page says monthly payments are often significantly higher in repayment, and in some cases the full balance is due when repayment begins. The agency also describes HELOCs as usually carrying variable rates.
• Renewal options. The CFPB’s HELOC brochure says some lenders let the borrower renew the line or leave it open once repayment ends. An old agreement may therefore offer an option that avoids a refinance.
• Floating to floating. Replacing a variable line with another variable line trades one risk for the same risk. That is a real tradeoff for an investor who wants cost certainty.
• Recent purchase or listing. A property listed for sale, or listed in the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
• Credit and DTI. A score below 700 ends the investment-line path. A DTI above 50% does the same, even with plenty of equity.
• Bankruptcy or foreclosure history. A bankruptcy needs 4 years of seasoning. Investment files follow a 7-year foreclosure path and a 4-year path for a deed-in-lieu, pre-foreclosure, or short sale.

Key Terms Defined

Draw period: The stretch when the borrower can take money from the line, usually with interest-only payments.

Repayment period: The stretch after the draw ends, when borrowing stops and principal is repaid.

CLTV: Combined loan-to-value, meaning all liens on the property divided by its value.

Subordination: A written agreement that lets a junior lien stay behind a new first mortgage.

Balloon payment: A lump sum that comes due in full at the end of a term.

DSCR: Debt service coverage ratio, meaning rent divided by PITIA (principal, interest, taxes, insurance and any association dues).

What Should an Investor Do Before the Draw Ends?

Work backward from the draw end date, and start with the paperwork rather than the lender.

• Audit the old agreement for the end date, repayment term, balloon language, renewal option and closure fee.
• Add up combined leverage against a realistic value for the rental.
• Check credit, DTI and title. If the property sits in an LLC, plan a vesting change or a DSCR cash-out.
• Stress-test the repayment payment against the property’s real operating cash flow, not just its rent.
• Line up a fallback. If the new line is declined, a DSCR cash-out or a paydown is the next path.
• Once the payoff happens, confirm the release is filed and the old line is closed.
