Investment Property HELOC Requirements for Combined Leverage on a Rental

The Quick Read: On an investment property, a home equity line is sized by combined leverage: the first mortgage plus the new line cannot exceed 70% of the property’s value, the borrower needs at least a 700 credit score, the line tops out at $500,000, and the property must be titled to an individual or revocable trust. These are typical wholesale-network ranges, subject to lender guidelines and full file review. Lendmire is a broker and arranges these lines through select lenders; it is not the lender.

• Combined cap: 70% CLTV on an investment property, whether the line sits in first or second lien position.
• Credit: 700 is a hard floor. A 720 score reaches the same 70% ceiling, so a higher score buys eligibility, not extra leverage.
• Size: $25,000 to $500,000 on a rental, with automated valuation as the usual route.
• Title: Individual or revocable living trust only. An LLC cannot hold title on this product.
• Qualification: The borrower is underwritten on credit and debt-to-income (50% maximum), not on rent coverage.

What Does a Lender Require on a Rental Equity Line?

A rental equity line is underwritten mainly on the borrower. Across the wholesale network, the lender looks at credit, available equity, debt-to-income, the property type, and how the property is titled.

The occupancy of the property sets the ceiling. The table below shows why a rental line should never be sized from a primary-home example.

The 90% figure exists only for primary residences and second homes at a 720-or-better profile. Market surveys often quote equity-line limits that look higher than the investment tier here, and those describe the broader market, not this network. On an investment property the network ceiling is 70% CLTV.

Several other requirements shape the file:

• Debt-to-income: The maximum is 50%, and it drops to 45% for credit profiles from 600 to 679. Lenders qualify the borrower on the interest-only payment calculated on the maximum draw, not the amount drawn on day one. On an investment line the 700 credit floor sits above that range anyway.
• Credit report: 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.
• Bankruptcy: Lenders want 4 years of seasoning from discharge or dismissal.
• Foreclosure history: Investment files follow a 7-year path for a foreclosure and a 4-year path for a deed-in-lieu, pre-foreclosure, or short sale.
• Portfolio size: A borrower with more than 15 financed properties is not eligible.
• Line count: A borrower is limited to three lines, and a combined-exposure cap applies across them that differs by wholesale program.
• Availability: These lines are offered only in the 16 states where Lendmire operates full-service, which is narrower than its 41-market DSCR footprint (40 states plus Washington, D.C.)

Property type matters too. Single-family, 2-4 unit, PUD, townhome, and condominium properties (including non-warrantable condos) can be eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.

How Is Combined Leverage Calculated on a Rental?

Combined leverage is every lien on the property, including the new line, divided by the property’s value. The formula is the standard combined loan-to-value calculation, as Yahoo Finance’s CLTV explainer shows. For the maximum line, flip it around:

The rental’s rent does not enter the formula on a personally underwritten line, so a strong lease cannot create room that the equity does not have. Three first-mortgage positions show how it plays out, with every figure expressed as a share of value:

Valuation sets the denominator. Because an investment line caps at $500,000, and full appraisals begin only above that size, a rental line normally runs on an automated valuation with no traditional appraisal. A borrower may still request a full appraisal in any case. A higher or lower value estimate moves the available room directly, which is why a small valuation gap can decide whether a thin-equity file works.

One structural detail affects how the math works in practice. On an investment line, at least 75% of the line is drawn at closing. So the CLTV the lender evaluates is close to the full limit, not a small starting balance. Plan around the full line.

Key Terms Defined

Combined loan-to-value (CLTV): The total of all mortgage balances secured by the property, including the new line, divided by the property’s value.

Open-end line of credit: A line you can borrow against repeatedly up to a limit, which the CFPB’s HELOC overview describes as having a draw period followed by a repayment period.

Draw period: The stretch when interest-only payments apply and additional borrowing is allowed. On an investment line, this runs 5 years, followed by a 25-year fully amortizing repayment period.

Subordinate lien: A second mortgage that sits behind the first in repayment priority. A standalone line can sit in first or second position.

Vesting: How title to the property is held. Individuals and inter vivos revocable living trusts qualify; LLCs, corporations, partnerships, and irrevocable, blind, or land trusts do not.

Equity: What the property is worth minus what is owed against it. The CFPB’s HELOC booklet explains the credit limit as a percentage of the home’s value, minus the mortgage balance. That is the same logic as the formula above, with a lower percentage applied to rentals.

Where Do the Rules Break Down?

Most investors hit one of five edge cases. Each one changes the answer.

The property sits in an LLC. This is the sharpest difference from a DSCR loan. A rental already deeded to an entity cannot take this line unless the investor changes vesting to a personal or revocable-trust name. The alternative is a DSCR cash-out refinance, which can accommodate entity-titled properties, subject to lender program eligibility. Changing title on a property with an existing mortgage can have its own consequences, so the investor should confirm the first mortgage’s terms before moving the deed.

The first mortgage already uses the cap. A first lien near 70% of value leaves no room for a second lien. Credit above 700 does not change that, and neither does rent.

The line goes in second position behind a DSCR or conventional first mortgage. The existing first-lien note must allow a subordinate lien. The line can also sit in first position on a paid-off rental, which is a cleaner structure with the same 70% CLTV ceiling.

The investor lives in one unit of a small multifamily. If the borrower occupies a unit of a 2-4 unit property, the property may be treated as a primary residence rather than an investment. That moves the file into the higher-ceiling occupancy tier. When every unit is rented, the investment tier applies.

The investor owns many properties. Each line is secured by one property, so a portfolio gets separate lines rather than one pooled facility. The three-line and combined-exposure limits mean a larger portfolio can run out of room before it runs out of equity.

There is also a trap on the consumer side. Lines written for a primary residence can carry terms that restrict renting out the home, and the occupancy declared at application must match how the property is used. Do not use a primary-residence line to fund a rental purchase against a home that stops being owner-occupied.

How Does the Payment Structure Affect a Rental?

The payment structure is the main modeling risk. Pricing on these lines floats across both the draw and the repayment period and never converts to fixed. The monthly obligation therefore moves with the balance and the market, and it steps up when the interest-only draw ends and amortization begins.

An investor comparing this to a fixed-rate DSCR note should model the line with the full amortizing payment in mind, not just the interest-only draw. A rental that covers its costs during the draw period can look different once repayment starts.

Missing payments on a line secured by the property puts that property at risk, as the CFPB’s HELOC overview notes. For an investor, the line also has to be paid in full when the property is sold or refinanced.

HELOC or DSCR Cash-Out: Which Fits?

The decision often turns on one question: is the existing first mortgage worth keeping? A line keeps it in place. A cash-out refinance replaces it. Lendmire’s complete DSCR loans guide covers the second path in depth.

The DSCR path qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Coverage of 1.00 is where select programs start, and stronger ratios open better terms. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Short-term rentals sit lower, at 70% on a cash-out.

Clearing 1.00 does not mean positive cash flow. The calculation compares rent only to principal, interest, taxes, insurance, and any HOA dues. Repairs, vacancy, management, and utilities sit outside it.

The flip points are clear enough to state plainly:

• Keep the first mortgage and add a line when the first mortgage’s terms are worth protecting, the property is in an individual or trust name, credit is 700 or better, and the equity cushion is wide.
• Replace the first mortgage with a cash-out when the property is in an LLC, when personal DTI is tight, or when a fixed structure matters more than keeping the old note. Rent coverage then becomes the main test.
• Consider neither when the first mortgage already sits near 70% of value. No product creates equity that is not there.

What Should an Investor Do Before Applying?

Work the sequence in order, because each step can end the file.

1. Confirm the vesting. If the title is in an LLC, decide between a vesting change and a DSCR cash-out before anything else.

2. Run the formula. Take 70% of a realistic value, subtract the first mortgage, and compare the result to the $25,000 minimum and $500,000 cap.

3. Check the credit profile. Anything under 700 removes this product for an investment property.

4. Stress the payment. Model the amortizing payment after the draw period, not just the interest-only draw.

5. Count existing lines. The three-line and 15-property limits apply across the borrower’s whole portfolio.

6. Review the first-mortgage terms if the new line will sit in second position.
