Investment Property HELOC Requirements for a Single-Family Home

The Quick Read: Across Lendmire’s wholesale network, a line on a single-family rental is underwritten on the borrower’s credit, income, and equity, with a 700 minimum credit profile and a 70% combined loan-to-value ceiling. The line is borrower-qualified, so rent alone does not carry the file the way it does on a DSCR loan.

• Credit: 700 is a hard floor. A 720 profile reaches the same 70% CLTV ceiling, so a higher score adds eligibility, not leverage.
• Line size: $25,000 to $500,000 on an investment property, which keeps most files in the automated-valuation lane.
• Title: The deed must sit with an individual or a revocable living trust. An LLC cannot hold title.
• Structure: A five-year interest-only draw, then a 25-year amortizing repayment. Pricing floats the whole way.
• Where it applies: HELOC availability is limited to Lendmire’s 16 full-service states, which is narrower than its DSCR footprint.

What Is a HELOC on a Single-Family Rental?

A HELOC on a rental is a revolving line secured by the investment home. It can sit in first-lien position if the property is paid off, or in second position behind an existing mortgage. You draw what you need, pay interest on what you use, and repay when the draw period ends.

Many banks will not write one on a rental at all. Others treat it as a business line and underwrite it more tightly than a line on a primary home. Lendmire is a broker, not a lender. It places these lines with select wholesale partners, and each partner sets the final terms.

Single-family homes are the easiest rental type to place. Condos, townhomes, PUDs, and 2-4 unit properties are also eligible, but the single-family house is the cleanest collateral. Manufactured homes, log homes, co-ops, condotels, and commercial or mixed-use properties are not offered.

How Underwriting Treats the Line, Step by Step

1. The property and the title. Underwriting starts with who owns the home. Title must be held by the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on this product. In Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington, a home that is listed for sale, or was listed within the past 60 days, is ineligible.

2. The equity test. Lenders measure combined loan-to-value, or CLTV. That adds the new line to every lien already on the home and divides by the home’s value. On an investment property the ceiling is 70% CLTV.

The available line is roughly 70% of value, minus what you already owe, and never more than $500,000. Take a home worth 100 units with a first mortgage equal to 50% of value. The line could reach about 20% of value, before the size limits apply.

3. The credit test. The investment floor is 700. The network uses a single-bureau score keyed to the primary wage earner. The report must be no more than 90 days old at closing, and there are no rescores. Past credit events also matter. A bankruptcy needs four years of seasoning from discharge or dismissal. A foreclosure needs seven years. A deed-in-lieu, pre-foreclosure, or short sale needs four.

4. The income test. Maximum DTI is 50%. Underwriters calculate the payment on the interest-only amount at the maximum draw, not on what you plan to borrow first. A large line therefore stresses DTI even if you intend to draw lightly. Because the investment floor is already 700, the lower-score DTI tiers do not come into play.

5. The valuation. Lines at or below $500,000 ordinarily use an automated valuation model. Full appraisals begin above $500,000, which an investment line cannot reach. A borrower may still request a full appraisal. That can help when a recent renovation added value an automated model would miss, though a higher CLTV may also trigger a secondary valuation.

6. The draw. At least 75% of the line is drawn at closing. After closing, the minimum subsequent draw is generally $1,000. Plan the line as mostly funded from day one, not as an idle reserve.

Requirements Table: Investment Line vs. Primary Residence

The gap is large. A primary home can reach a much higher ceiling, but only at a 720 profile, and that tier does not apply to a rental. The network figure for an investment line is 70% CLTV.

How the Payment Behaves

The CFPB’s HELOC explainer notes that HELOCs usually carry variable pricing, so payments can change from month to month. It also notes that some plans let you convert part of the balance to a fixed structure. On this network’s investment line, pricing floats across both the draw and the repayment period and never converts to fixed.

The CFPB’s HELOC booklet describes the shift from draw period to repayment period. That shift is the stress point. During the five-year draw the payment is interest-only. In repayment, the balance amortizes over 25 years, so the monthly obligation rises even if nothing else changes.

Investors who plan to hold a balance should model the repayment period, not just the draw. A line that cash-flows on interest-only can look different once principal starts. Lenders do not model that for you.

Where the General Rule Breaks

The LLC-held rental. An investor who deeded the house to an LLC for liability reasons will find that this line cannot attach to it. The options are a vesting change into personal or revocable-trust ownership, or a different product. A DSCR cash-out refinance can work for entity-held rentals, subject to lender program eligibility.

The portfolio landlord. A borrower may hold no more than three of these lines. Combined exposure caps at $750,000 on one partner program and $2,000,000 on another. A borrower with more than 15 financed properties is not eligible. Larger portfolios tend to land in DSCR territory by default.

The score sitting at 690. Many investors assume a 690 profile will get a smaller line. It will not. There is no tier beneath 700 on an investment property. Raising a score from 690 to 700 changes eligibility. Raising it from 700 to 740 does not change leverage.

The high DTI. A rental owner with several mortgages, a high personal debt load, or variable self-employment income may fail the 50% DTI test even with plenty of equity. This is where borrower-underwritten lines and rent-qualified loans diverge.

The recent purchase. Seasoning matters. Many lenders want a meaningful ownership period before lending against the equity, and the wholesale partners vary on exactly how long. A just-bought rental is a weak candidate for this product.

The unusual property. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs either. The same goes for commercial, mixed-use, and agricultural-zoned parcels. A Texas property is limited to 10 acres, and Texas investment properties are eligible as non-homestead transactions.

HELOC, Cash-Out Refinance, or DSCR Loan?

A line suits a different borrower than a rent-qualified loan does. Here is the structural comparison.

A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Most select programs in the network start at 1.00 coverage, and stronger ratios tend to open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. The 1.00 level is where many select programs begin. It is not a universal rule.

Clearing 1.00 also does not mean the rental produces positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.

On the DSCR side, purchase leverage on most files lands at 75% to 80% LTV, with select high-leverage programs reaching 85% at roughly a 700 score. Credit floors reach as low as 620 in parts of the network, most programs want around 660, and 700 and above unlocks the strongest tiers. Reserves vary by lender, leverage, and loan size. Around six months of PITIA is common, and conservative files at modest leverage under $1,500,000 can see them waived. Larger loans typically step up to about nine months. Loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders.

If you are weighing these two lanes, Lendmire’s complete DSCR loans guide walks through the DSCR side. DSCR programs are available across 41 markets, including Washington, D.C., while the equity line covers only 16 states.

When the HELOC is the right tool: you hold the rental personally, your first mortgage should stay in place, your income and DTI are strong, and you want a draw you can use in stages. A piece Best Investment Property HELOC Program for a Single-Family Home goes further into program fit.

When it is the wrong tool: the deed is in an LLC, your DTI is above 50%, you need more than $500,000, or you want leverage above 70% on the rental. In those cases, a DSCR loan or a vesting change deserves a look first.

Key Terms Defined

CLTV: Combined loan-to-value is the total of all liens on the home, including the new line, divided by the home’s value.

DTI: Debt-to-income compares your monthly debt payments with your monthly income.

Draw period: The stretch when you can borrow against the line, interest-only on this product, for five years.

Repayment period: The stretch after the draw ends, when the balance amortizes over 25 years.

DSCR: Debt service coverage ratio is monthly rent divided by the monthly PITIA, the rental’s principal, interest, taxes, insurance, and any HOA dues.

Automated valuation: A computer estimate of value used in place of a full appraisal on smaller lines.

What the Decision Looks Like in Practice

Start with ownership. If the home is in your name or a revocable trust, the line is possible. If it is in an LLC, plan for a title change or a different product.

Next, check credit against 700. Then estimate CLTV from the home’s likely value and every lien on it. Run DTI at the maximum draw, not the amount you plan to use. Finally, decide how much of the line you actually need, since at least 75% is drawn at closing and floats from there.
