Can You Get an Investment Property HELOC With One Unit Vacant?

The Quick Read: Usually yes, because a standard investment-property HELOC is approved on your credit, income and debts rather than the building’s rent, so an empty unit does not automatically disqualify the file, as long as the unit is held for rent and the building is a duplex, triplex or fourplex titled in your own name or a revocable trust. Lines that qualify on rental income work differently, because there the vacancy changes the math.

• On an investment property, the network’s equity line tops out at 70% CLTV, with a $500,000 maximum line and a 700 minimum credit score.
• Rent does not count toward qualifying on that line, so a vacant unit and a leased unit follow the same underwriting.
• The payment does not pause while the unit sits empty, so the line is a cushion, not a vacancy fix.

A HELOC, short for home equity line of credit, is a revolving credit line secured by the property.

Why an Empty Unit Doesn’t Sink a Standard Line

The standard investment HELOC is a borrower-qualified product. The lender looks at your credit score, your income, your other debts and the equity in the building. Rent from the units is not the qualifying income, so one empty unit is not a test the file has to pass.

This is a different animal from the loans most landlords know. A DSCR loan (debt service coverage ratio, meaning rent measured against the property’s full monthly payment) lives and dies on rent. A HELOC on the network’s investment line ignores it.

That does not make the product easy. NerdWallet notes that an investment-property HELOC is not offered by all lenders and carries strict requirements. It explains that lenders see higher default risk because borrowers are more likely to protect their own home than a rental.

So the real question is rarely whether the vacant unit kills the deal. It is whether a lender will offer the line on your building at all.

What the Investment Line Requires

Across the wholesale network Lendmire places files with, the investment equity line follows a tight set of ranges. Every figure here is typical for select lenders in the network, subject to lender guidelines and full file review.

• Leverage: 70% CLTV on an investment property. Both the 700 and 720 credit tiers reach that same cap, so a higher score above 700 buys no extra leverage.
• Credit: a 700 minimum on an investment line, with no tier beneath it.
• Line size: up to $500,000 on an investment property. Larger lines exist only for primary residences.
• Debt-to-income: up to 50%, qualified on the interest-only payment at the maximum draw.
• Structure: a standalone line in first or second lien position, with a five-year draw period and a 25-year repayment period. At least 75% of the line is drawn at closing, and the pricing floats rather than converting to fixed.
• Valuation: because the line caps at $500,000, it commonly runs on an automated valuation with no traditional appraisal. You can request a full appraisal in any case.
• Property types: single-family, 2-4 units, townhomes, PUDs and condos, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agriculturally zoned properties are not eligible.
• Exposure: a borrower is limited to three lines, and owning more than 15 financed properties makes you ineligible.

Market numbers look different. On the network, an investment line is capped at 70% CLTV.

The equity line is also offered in a narrower set of states than DSCR loans, so availability is the first check.

The 75% drawn at closing makes the product behave like a loan with a small standby slice rather than a pool of idle cash. Plan for that before you apply.

Where Vacancy Does Matter

Vacancy matters the moment rent becomes the qualifying income. That happens on income-qualified lines and on a DSCR cash-out refinance, which replaces your first mortgage with a larger one and is sized on rent.

Some income-qualified lines cap vacancy at one unit in a 2-4 unit building and want a lease in place. Published rules for these lines often do not say how the empty unit is counted, so ask the lender directly. Expect the answer to differ by lender.

A partly vacant building usually mixes leases for the occupied units with market rent for the empty one. A vacant unit that is rent-ready generally counts at market rent. A unit that is not lease-ready is an eligibility problem, not a rent problem. On a 2-4 unit refinance, one or two vacant units can get more flexibility because the occupied units still show income.

How Lenders Read Each Kind of Vacancy

Not every empty unit is the same kind of empty. The type of vacancy changes how a lender reads it, and which product you chose changes it again.

The listing row catches landlords off guard. A building listed for sale within the past 60 days is ineligible on the network’s line in a handful of states. If you listed a vacant unit while weighing your options, that clock may matter.

The Duplex Test: A Worked Example

Run the numbers on a modeled duplex with two equal units. Assume the building clears about 1.4x coverage when both units are rented. That means rent is 1.4 times the full monthly payment of principal, interest, taxes, insurance and any association dues, known as PITIA.

Now one unit goes empty. If a lender counts only signed leases, only half the rent remains, and coverage falls to roughly 0.7x. If the vacant unit is rent-ready and the lender counts it at market rent, the building still reads near 1.4x.

Those two outcomes are why the product lane matters. A borrower-qualified line skips this exercise entirely. A rent-based path turns on how the lender treats the empty unit.

Coverage below 1.00 is not a dead end on the DSCR side. Select lenders in the network offer sub-1.00 paths with leverage and terms adjusted. Still, 1.00 is where many select programs start, and stronger ratios open better terms and leverage.

One caution about the ratio itself. Clearing 1.00 does not mean the property produces positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation.

Which Product Fits Your Building?

Three routes can pull equity out of a partly vacant small multifamily. They answer different questions.

On the DSCR side, LLC-titled borrowers can generally qualify, subject to lender program eligibility. That is the sharpest structural difference from the network’s standard HELOC, which requires title in an individual’s name or a revocable living trust. If your building is already deeded to an LLC, you either change the vesting or look at DSCR cash-out instead.

Leverage differs too. A DSCR cash-out refinance on a standard rental tops out around 75% LTV across most of the network, and 70% on short-term-rental collateral. It typically expects about six months of seasoning, meaning time owning the property. Credit floors start at 620 in parts of the network, most programs want around 660, and 700 or better unlocks the strongest tiers.

The keeping-the-first-mortgage question is where many investors decide. A HELOC leaves your first mortgage untouched, which helps if that loan is a low-cost one. A cash-out refinance replaces it. BiggerPockets threads include a banker’s reply on this exact tradeoff, which is anecdotal, so weigh it as one voice.

Lendmire’s complete DSCR loans guide walks through how property-rent-based lender review works if the second route fits better. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.

DSCR loans are not offered on manufactured homes, log homes or barndominiums, so those buildings are out on either path.

Stress-Test the Vacancy Before You Draw

A line that approves easily can still hurt you. Treat the line as a short-term cushion.

Here is a simple way to stress-test it before you commit.

1. Count only the units you can rely on. Set the empty unit’s rent to zero.

2. Add every obligation. Stack the first mortgage payment, the new line’s payment and the building’s operating costs.

3. Add a turnover buffer. Assume the vacant unit takes a while to lease, and the next tenant might too.

4. Check the draw schedule. The line floats during both the draw and repayment periods, so the payment can move.

5. Ask what happens if the value dips. A lender may stop further draws if the property value falls significantly, per the CFPB’s HELOC explainer. That risk is sharper for a rental in a soft market.

If the building only works with the vacant unit leased, the unit’s empty status is the real problem, not the financing. Lease it first, then borrow.

Also read the fine print on rentals. The CFPB’s HELOC brochure is written for homeowners borrowing against their own home. It notes that renting out your home may be prohibited under the terms of a line of credit.

Edge Cases That Change the Answer

• You live in one unit. The building is treated as owner-occupied, which carries a different ceiling and credit floor than an investment line. A vacant unit next to your own is a normal house-hacking setup.
• More than one vacant unit. A borrower-qualified line has no published vacancy test, but a lender may still decline. A rent-based line is stricter.
• Five or more units. That is commercial-style underwriting, not a HELOC.
• A unit that is not rent-ready. This reads as an eligibility issue on the DSCR side, and it can complicate a valuation anywhere.
• Existing liens. The network’s line can sit in first or second position, so a building with a first mortgage can still be a candidate.
