Investment Property HELOC Requirements With One Unit Vacant

The Quick Read: A vacant unit does not by itself disqualify an investment property line when the lender qualifies the borrower on personal credit, debt-to-income and available equity, because the line does not count the building’s rent; the vacancy matters instead for carrying cost, while lenders that credit rental income will discount or exclude the empty unit’s rent.

• On an investment property, the ceiling across Lendmire’s wholesale network is 70% CLTV, with a 700 minimum credit score.
• Lines on an investment property run from $25,000 to $500,000.
• Title must sit with the individual borrower or a revocable living trust, not an LLC.
• The debt-to-income cap is 50%, measured on the interest-only payment at the maximum draw.
• The payment does not pause while the unit sits empty.

What the Vacancy Question Actually Changes

The vacancy changes the cash-flow cushion, not the paperwork, on most equity lines placed through a wholesale network. Underwriting looks at the borrower first and the building second. The empty unit becomes a risk you carry out of your own pocket.

That is why you see conflicting advice online. Some lenders credit rent toward qualifying, so an empty door hurts the file. Others ignore rent entirely, so an empty door barely registers. Both statements are true. They describe two different products.

If you are comparing offers, the first question for any lender is simple. Does this line count the building’s rent, or only my personal income?

Two Underwriting Models, Side by Side

Borrower-qualified lines size the file on credit, debt-to-income and equity. Rent-qualified lines also credit lease income, so vacancy cuts into the usable number. Which model applies decides how much the empty unit matters.

The placements Lendmire arranges on investment properties follow the borrower-qualified model. A tenant-occupied building and a half-empty one are reviewed on the same borrower factors. That does not make the vacancy free. It moves the vacancy risk onto your balance sheet.

Many large lenders decline investment-property lines altogether. Those that offer them often structure them as business lines. A BiggerPockets Rookie episode notes that many lines on investment properties are really commercial lines of credit, and the speaker’s lender required the properties to be held in LLCs.

The Requirements, Step by Step

An investment line through the network needs a 700 credit score, up to 70% CLTV, a DTI of 50% or lower, and individual or revocable-trust title. Every figure below is subject to lender guidelines and full file review, and none is a commitment to lend.

1. Pick the product. Lendmire brokers a standalone line in first or second lien position. It is not a lender, and each partner reviews and approves its own files.

2. Size the line. The ceiling on an investment property is 70% CLTV, meaning your first mortgage plus the new line against the property value. A 720 score and a 700 score both reach that same 70%, so credit above 700 buys eligibility rather than extra leverage. Below 700, an investment line is not available.

3. Check the amount. Investment lines run from $25,000 to $500,000. Anything larger is reserved for primary residences.

4. Understand the structure. Investment lines use a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats through both periods and never converts to a fixed term.

5. Qualify on DTI. The cap is 50%. The payment used is the interest-only payment calculated on the maximum draw, whether or not you plan to draw it all.

6. Expect an automated valuation. Because investment lines cap at $500,000, they usually run on an automated valuation with no traditional appraisal. A borrower may request a full appraisal in any case. That matters after a recent rehab, when an automated model may lag the improved value.

7. Credit report details. 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, and rescores are not allowed.

Prior credit events carry seasoning. A bankruptcy needs four years from discharge or dismissal. On investment files, a foreclosure needs seven years, and a deed-in-lieu, pre-foreclosure or short sale needs four.

Property types include single-family, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not offered.

What Counts as Vacant?

The type of vacancy matters less to a borrower-qualified line than to a rent-qualified one. It matters most for your own carry. The table shows the likely reaction in qualitative terms.

In several states, a property listed for sale, or listed within the past 60 days, is ineligible for these lines. If you are testing the market on an empty unit, confirm the listing history before you apply.

Duplex, Triplex, Fourplex: How One Empty Door Scales

One empty unit weighs differently in each building size, and a duplex feels it most. In a duplex, vacancy cuts half the income. In a triplex it is one-third. In a fourplex it is one-quarter.

On a borrower-qualified line, none of those fractions changes eligibility. They change how long you can carry the building without strain. A fourplex with one empty door generally keeps three-quarters of its income flowing toward the payment on any line you draw. A duplex with one empty door leaves you leaning harder on your own income.

On a rent-qualified line, the same fractions hit the coverage figure directly. A lender may exclude the empty unit or substitute a discounted market rent. No neutral source supports a standard haircut, so treat any number a lender quotes as that lender’s own policy.

Single-family is the cleanest contrast. A fully empty single-family rental has no income at all. A borrower-qualified line still looks at you, while a rent-qualified line has nothing to credit.

Where the General Rule Breaks

The rule that a vacancy does not disqualify the file has real exceptions. These are the named edge cases.

Title held in an LLC. Equity lines on investment properties require title in your own name or a revocable living trust. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title. This is the sharpest structural difference from a DSCR loan. A property already deeded to an LLC needs a vesting change or a DSCR cash-out refinance instead.

Too many lines or properties. A borrower is limited to three lines, with combined exposure caps that run from $750,000 to $2,000,000 depending on the wholesale program. A borrower with more than 15 financed properties is not eligible.

A line above $500,000. That size exists only on primary residences, so it cannot sit on a rental.

Coverage depends on location. These lines are placed in Lendmire’s 16 full-service states. That is narrower than its DSCR investor loan footprint of 41 markets, including Washington, D.C.

A house-hack with one unit empty. If you live in one unit, the property may fall under primary-residence terms rather than investment terms. The occupancy classification, not the vacancy, sets the ceiling. When you ask for a quote, state which occupancy applies. Stating the wrong one can change the CLTV by a wide margin.

Drawing against your own home. You can sometimes borrow against a primary residence and use the cash on the rental. The lender then looks at the primary home’s equity, and the rental’s vacancy matters less. The primary residence has its own ceilings, which are higher but require stronger credit.

The Carry Test: What an Empty Unit Costs While the Line Is Open

The line stays open and the payment keeps running while a unit sits empty. The CFPB describes a HELOC as an open-end line you can borrow against repeatedly, with a draw period that could last 10 years, for example. It also notes that minimum payments are typically based on the current balance and that most lines carry a variable rate, so payments can change month to month.

Two features of the network’s investment structure sharpen that point. First, at least 75% of the line is drawn at closing, so interest starts on most of the balance from the first day. Second, pricing floats and never converts to fixed. The CFPB’s HELOC brochure walks through the draw period, the repayment period and the variable-rate mechanics, which is a useful read before you sign anything.

A practical stress test follows. Take the building’s other income and your personal income, and ask whether they carry the full line payment, the first mortgage and operating costs while the empty unit stays empty for a stretch. If the answer depends on the unit leasing up on schedule, the line is too large. An equity line works best as a short-term cushion, not as a bridge that only works if everything goes right.

Lease First or Apply First?

Apply first when the line is borrower-qualified and your own income carries the building. Lease first when the lender credits rent, or when an appraisal will matter.

• Borrower-qualified line, strong personal income: Applying now is reasonable. The vacancy does not change the qualifying math.
• Rent-qualified line: Leasing up first can raise the rent the lender counts.
• Recent rehab on an automated valuation: Waiting, or requesting a full appraisal, may capture the improved value. Any improvement may support a higher appraised value, depending on comps and underwriter review.
• Unit listed for sale: Take it off the market and check the listing rules for your state.

The flip point is reserves of cash. If the empty unit would drain your personal cushion within a few months, leasing first is the safer decision regardless of how the line is qualified.

When a DSCR Cash-Out Is the Better Path

A DSCR cash-out refinance is the alternative when title sits in an LLC, the line cap is too small, or you would rather qualify on the property than on personal debt ratios. DSCR loans compare rent to the full housing payment, which is principal, interest, taxes, insurance and any association dues. They qualify primarily on property-level rental income covering the payment, subject to lender guidelines. The complete DSCR loans guide covers the mechanics in full.

The cash-out path has its own vacancy rules. A vacant property is reviewed on the appraisal’s market rent. A vacant unit in a multi-unit building can lower the income figure, depending on program guidelines. Select lenders sometimes show more flexibility on a multifamily refinance when only one or two units are empty. A cash-out typically expects about six months of seasoning and a loan between $100,000 and $3,000,000.

Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing the ratio is not the same as positive cash flow, because repairs, vacancy, management, utilities and capital costs all sit outside the calculation.

Key Terms Defined

CLTV: Combined loan-to-value, which adds your first mortgage and the new line together and divides by the property value.

Draw period: The stretch of time when you can borrow from the line and pay interest only.

Repayment period: The stretch after the draw period when the balance amortizes and the payment includes principal.

Automated valuation: A computer-generated property value used in place of a traditional appraisal.

DTI: Debt-to-income, the share of your monthly income that goes toward debt payments.

DSCR: Debt service coverage ratio, the property’s rent divided by its full monthly housing payment.
