What an Investment Property HELOC Lender Wants If a Relative Pays No Rent

The Quick Read: Usually, yes, you can still apply, because a standard investment-property home equity line is underwritten on your credit, debt-to-income, equity, and title rather than on tenant rent, but the lender will classify the property as non-owner-occupied investment use, apply the tightest investment limits, and count no rental income from a relative who pays nothing. The rent-free arrangement matters far more on rent-based loans, where the property’s income is the qualifier. Lendmire is a mortgage broker, so it matches the file to the right program instead of forcing one product to fit.

• Free use by a relative earns neither owner-occupied nor second-home treatment.
• On an investment property line, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit score and a $500,000 maximum line.
• A relative paying $0 gives you no documentable rent, so rent cannot help you qualify.
• Converting to a written lease at or near market rent opens rent-based options, such as a DSCR cash-out refinance.
• Everything here is subject to lender guidelines and full file review. None of it is a commitment to lend.

Key Terms Defined

Non-owner-occupied: a property you do not live in as your primary or second home. Rent-free use by a relative still counts here.

CLTV (combined loan-to-value): all loans secured by the property, added together, divided by its value.

HELOC: a home equity line of credit, a revolving line secured by the property. You draw on it as needed up to a set limit.

DSCR (debt service coverage ratio): monthly rent divided by the full monthly housing obligation, meaning principal, interest, taxes, insurance, and any HOA dues. That obligation is called PITIA.

Market rent schedule: an appraiser’s opinion of what the unit would rent for. It is Form 1007 for a single unit and Form 1025 for two to four units.

Vesting: the name or entity on the property’s title.

How Does a Lender Classify a Property a Relative Lives In for Free?

A lender classifies it as an investment property. Rent-free family use does not qualify as owner-occupied, because you do not live there. It does not qualify as a second home either, because a second home is one you occupy yourself.

That classification drives everything else. Investment lines sit on the strictest tier of any product in the HELOC category. Across the wholesale network Lendmire works with, the ceiling on an investment line is 70% CLTV, and no tier sits above it. Primary-residence and second-home lines can reach 90% CLTV, but only at a 720-or-better credit profile, and that ceiling never applies to a property a relative occupies for free.

Some owners hope to call the arrangement a second home or a primary residence to reach those higher tiers. Skip it. Occupancy is a statement you sign on the application, and misstating it puts the loan itself at risk. Classify it honestly and build the file around the investment tier.

If the relative pays rent under a lease, the property is still investment, now tenant-occupied. The label does not change, but the file gets better documentation.

Does Having No Rent Hurt an Investment HELOC?

Usually not much, because the standard investment HELOC is a personal-credit product. The lender reviews your credit, debt-to-income, equity, and title. Rent can support the file, but rent does not decide it. A vacant property, a leased property, and a property with a relative living in it all run through the same core math.

Here is what the network’s investment line looks for, with each figure applying only to an investment property:

• Leverage: up to 70% CLTV. Scores of 700 and 720 both reach that same 70%, so credit above 700 buys eligibility rather than extra leverage.
• Credit: a 700 minimum, with no tier beneath it.
• Debt-to-income: 50% maximum, qualified on the interest-only payment calculated at the maximum draw.
• Line size: $25,000 to $500,000. Lines above $500,000 are primary-residence only.
• Structure: a standalone line in first or second lien position, with a 5-year interest-only draw followed by a 25-year repayment period. At least 75% of the line is drawn at closing, and the line stays variable.
• Valuation: because an investment line caps at $500,000, it runs on an automated valuation, usually with no traditional appraisal. You can still request a full appraisal.

These are eligibility ranges from select wholesale lenders, and every file is reviewed individually.

The weak point is rarely the missing rent. It is usually equity. At 70% CLTV, your existing mortgage plus the new line must stay at or below 70% of the property’s value. A rent-free relative does not change that arithmetic in either direction.

Why Rent-Free Matters Much More on Rent-Based Loans

Rent-free occupancy is a real problem on any program that qualifies the property on its income. A DSCR loan needs a rent figure to put in the numerator. That figure comes from a signed lease, an appraiser’s market rent schedule, or both. Lenders commonly use the lower of the lease rent and the market rent.

A relative paying nothing produces no lease rent. That leaves you with an appraiser’s market rent opinion for a unit that is not actually being rented, and a lender may not treat that as a clean rental. Rent-free use has to change before a rent-based program fits.

One more point about the DSCR math. Clearing 1.00 means rent covers the payment, which is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the ratio. Treat the number as a lender’s test, not a profit forecast.

For the general mechanics of the product, see Lendmire’s complete DSCR loans guide.

What the Lender Asks For (and What a Clean File Looks Like)

A clean file answers the occupancy question before the lender has to ask it. Expect questions on who lives in the property, how long, and on what terms. Expect to say whether anything is in writing.

Prepare these items:

1. Occupancy statement. Plain wording: a relative lives there at no charge, and you do not occupy it.

2. Title and vesting. The deed must show you as an individual, or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on this product.

3. Credit and debt picture. A credit report no more than 90 days old at closing, plus your current obligations across all financed properties.

4. Existing liens. The balance on your first mortgage drives your CLTV.

5. Lease and payment records, if rent exists. A written lease and bank records showing the payments.

6. Property type check. Single-family, two to four units, PUDs, townhomes, and condos are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned property are not.

Two structural limits also apply. A borrower is limited to three lines on this program, and a borrower with more than 15 financed properties is not eligible. This HELOC program is available in 16 full-service states, which is narrower than Lendmire’s 41-market DSCR footprint, including Washington, D.C.

Scenario Table: Four Ways a Relative Might Occupy the Property

On a personal-credit HELOC, all four rows run through the same underwriting of you and your equity. On a DSCR loan, only the third row, market rent under a lease, is workable, and the below-market row cuts into coverage because the lender uses the lower of lease and market rent. Nothing about below-market family rent disqualifies a file on its own. It simply lowers the number.

A Worked Example: The Parent and the Adult Child

Picture a parent who owns a two-bedroom condo with a modest mortgage left. An adult child lives there and pays nothing. The parent wants a line of credit to fund repairs on a separate rental.

Here is how the file runs, step by step:

1. Occupancy. The condo is non-owner-occupied investment, because the parent lives elsewhere.

2. Title. The parent holds title personally, so vesting is fine.

3. Credit. The parent’s score needs to be 700 or better, since 700 is the hard floor for an investment line.

4. Equity. The existing mortgage plus the new line must total no more than 70% of the condo’s value. An automated valuation sets that value.

5. Debt-to-income. The parent’s total obligations, with the line payment calculated on the full draw, must stay at or under 50%.

6. Rent. None is counted, and none is needed on this product.

Now change one fact: the parent wants to cash out through a DSCR loan instead. At that point the rent-free arrangement blocks the path. The parent would need a real lease at a realistic rent, with payment records, before a lender could test coverage.

Should You Turn a Rent-Free Arrangement Into a Lease?

Often yes, if you plan to use any rent-based product. A written lease at or near market rent, with payments showing up in bank records, is the cleanest way to document income. It also forces an honest conversation about what the unit is worth.

There is a tax angle that goes beyond lending. The IRS says rent that is substantially below what similar nearby properties charge is not a fair rental price, and its Publication 527 gives the example of renting an apartment to your mother below fair rent as personal use. A Tax Notes summary of the publication covers the related rule for relatives who hold an ownership interest in the property. A FedLaws explainer notes that below-market family rentals can erase rental deductions. That is a tax rule, not an underwriting rule, but it explains why lenders do not treat a family arrangement as an ordinary rental. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.

A token rent does not fix the problem. If the lease sits far below market, a lender using the lower of lease and market rent will count the low figure, and your coverage drops with it.

What if the Property Does Not Fit the HELOC?

The property is in an LLC. An LLC cannot hold title on this HELOC. The property needs a vesting change, or a DSCR cash-out refinance is the better fit, subject to program eligibility.

You need more than the line allows. An investment line stops at $500,000 and 70% CLTV. A DSCR cash-out refinance on a standard rental tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. A short-term rental on a cash-out is capped at 70%. Coverage of 1.00 is where many select programs start, and stronger ratios open better terms. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Credit floors, reserves, and property eligibility still apply. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

Neither product is better in the abstract. The HELOC underwrites you, and the DSCR cash-out underwrites the rent. A rent-free relative hurts the second far more than the first.

Not every lender writes investment-property lines at all, which is why shopping matters. Lendmire’s piece on where to find lenders that write investment property lines covers that search.
