The Quick Read: A vacant unit does not by itself disqualify you, because the network’s investment-property line is underwritten on your credit, debt load, and equity rather than on the building’s rent. What matters is whether you clear the credit floor, stay under the combined leverage ceiling, and can carry the payments while the unit sits empty.
- On the investment line in Lendmire’s wholesale network, a 700 credit score is the hard floor and 70% combined loan-to-value (CLTV) is the ceiling on an investment property.
- A line on an investment property tops out at $500,000, so valuation usually runs on an automated model instead of a traditional appraisal.
- Rent-qualified lines work differently: some count rent unit by unit, and one empty unit then lowers your coverage.
- The title must be in your own name or a revocable living trust. An LLC cannot hold title on this line.
- The payments on the first mortgage and the line keep running while the unit is empty, so reserves matter more than the vacancy itself.
Does One Empty Unit Sink the Application?
The answer depends on which kind of line you are applying for. A HELOC on a rental comes in two underwriting styles, and a vacancy lands very differently in each.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
The first style is the personal-credit line. The lender looks at you: credit score, debt-to-income ratio (DTI), and how much equity remains after the first mortgage. Rent is secondary, and in the network’s investment line it is not the qualifying test at all. An empty unit shows up as a carrying-cost question, not an eligibility question.
The second style is the rent-qualified line, which the market sometimes labels a DSCR HELOC. That label is not a standardized product, and terms differ by lender. Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines. On some of these lines, a two-to-four-unit building may have at most one vacant unit, and the occupied units must carry the coverage.
Neither style is easy to find. NerdWallet reports that the lender pool for investment-property lines is smaller, borrowing limits are lower, and requirements are strict. Experian adds that these lines are generally harder to qualify for and that not every lender offers them. Across the wholesale network, the same pattern holds: fewer lenders, tighter overlays, and more focus on credit than on the lease file.
How Underwriting Treats the Building, Step by Step
Here is the sequence a file follows, with the vacancy in mind.
1. Pick the lane. Decide whether the file will be judged on you or on the property’s rent. If your credit is strong and your DTI is clean, the personal-credit lane makes the empty unit largely irrelevant. If your personal income is thin, the rent lane or a DSCR loan may fit better.
2. Check how the property is titled. The network’s investment line requires the individual borrower or a revocable living trust on title. A rental already deeded to an LLC needs a vesting change, or a different product altogether.
3. Pull credit. The line uses a single-bureau score model keyed to the primary wage earner. The report can be no more than 90 days old at closing. On an investment property, 700 is the floor.
4. Run DTI. The maximum is 50%. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you actually plan to borrow. A smaller draw does not shrink the number the lender tests.
5. Run the equity test. The lender adds the first mortgage and the new line, divides by the property value, and compares the result to the 70% ceiling. Equity is thin on many rentals bought recently with high leverage.
6. Value the property. Because an investment line caps at $500,000, valuation usually runs on an automated model. You can request a full appraisal in any case.
7. Document the rent, if rent is counted at all. In the personal-credit lane, a lender that counts rent typically applies a haircut for vacancy. A vacant unit contributes nothing to that figure. In the rent lane, expect leases on the occupied units and an income-based appraisal with a rent schedule.
That last point is where lanes diverge. An income-based investor loan on two to four units typically orders the agency’s Form 1025 operating income statement, and a rent schedule cannot support a unit nobody has leased. A credit-and-equity line skips that step, which is why a vacancy often matters little there.
How Each Kind of Vacancy Reads
Not every empty unit looks the same to a lender. The reason it is empty changes how the file is read.
| Vacancy type | Credit-and-DTI line | Rent-qualified line |
|---|---|---|
| Between tenants, rent-ready | Usually not an issue | Counts as the one vacant unit |
| Lease ending soon | Usually not an issue | Often treated like vacant |
| Never rented | Not an issue on its own | Needs market-rent support |
| Under renovation | Check property condition | Typically not rentable yet |
| Listed for sale | Ineligible in some states | Same state restrictions apply |
Two lines in that table deserve a closer look. A lease that expires next month tends to be treated like an empty unit, because the timing of the opening matters more than today’s tenant. And a unit under renovation is a different problem from a unit between tenants, since it may fail the property-condition review on top of producing no rent.
What One Vacancy Does to the Coverage Ratio
If your lender counts rent, the building size controls how hard one empty unit hits. The debt service coverage ratio (DSCR) divides the rent by the full monthly obligation. Take one unit out of the rent and the ratio drops by that unit’s share.
Run the numbers on a simple model. Assume every unit in the building rents for about the same amount. That is an assumption for illustration, not a market fact.
| Building | Rent left with one vacant | Full-occupancy coverage needed to still reach 1.00 |
|---|---|---|
| Duplex | 50% | 2.00x |
| Triplex | about 67% | 1.50x |
| Fourplex | 75% | about 1.33x |
Say you own a fourplex that covers its payment at roughly 1.40x when full. With one unit empty, coverage falls to about 1.05x. That is still above 1.00, which is where many select programs start. The same coverage on a duplex falls to 0.70x, which is a very different conversation.
Below 1.00 is not a dead end. A separate select-lender path takes coverage below 1.00 in the network, with leverage and terms adjusted. Clearing 1.00 also does not mean the building makes money. DSCR compares rent to the mortgage payment, taxes, insurance, and any association dues, and nothing else. Repairs, turnover, management, utilities, and capital expenses sit outside the calculation.
This is why the fourplex and the duplex deserve different strategies. A vacancy in a larger building is a cushion problem. A vacancy in a duplex is a coverage problem.
The Investment Line, Parameter by Parameter
Here is what the network’s investment-property line looks like. These are typical guidelines from select wholesale lenders, subject to full file review, and they are not a commitment to lend.
- Credit: 700 minimum. Credit above 700 does not buy more leverage on an investment property, because 720 and 700 both reach the same ceiling.
- Leverage: up to 70% CLTV on an investment property.
- Line size: up to $500,000 on an investment property. Larger lines are limited to primary residences.
- Structure: a standalone line in first or second lien position. Investment lines run a 5-year interest-only draw period followed by a 25-year fully amortizing repayment period. At least 75% of the line is drawn at closing. The payment floats and never converts to fixed.
- Exposure: a borrower is limited to three lines in total, and a borrower owning more than 15 financed properties is not eligible.
- Past credit events: a bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files a foreclosure needs 7 years, and a deed-in-lieu or short sale needs 4.
- Property types: single-family, two-to-four units, planned unit developments, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not eligible.
The 75% draw requirement matters for a vacant-unit borrower. Most of the line is outstanding from day one, so the interest-only payment starts at close to its full size. The CFPB explains in its HELOC overview that a line has a draw period followed by a repayment period, and that failing to repay can cost you the collateral. Its wording refers to a home, but the logic applies to any property pledged on the line.
For the equity math, think in percentages. Suppose the first mortgage sits at 55% of the property’s value. Under a 70% ceiling, the line can add up to about 15% of value, before the $500,000 cap and the other tests. The calculator on this site can convert percentages to dollars, as an illustrative estimate.
Where the General Rule Breaks
The rule that a vacant unit does not disqualify you has edges. These are the ones that trip files most often.
An LLC on title. Many investors hold rentals in an LLC for liability reasons. The network’s investment line cannot lend against LLC-held title, which is the sharpest structural difference from a DSCR loan. Moving the deed to your personal name is a decision to make with an attorney and your insurance agent first, because it changes your liability picture. For a rental held in an entity, a DSCR cash-out is usually the cleaner path, subject to lender program eligibility.
A property listed for sale. In several of the states where the line is offered, a property listed for sale or listed within the past 60 days is ineligible. An empty unit with a for-sale sign is a different file from an empty unit with a for-rent sign.
A fully vacant building. With no tenant and no rental history, the personal-credit lane can still work on credit and equity, since rent is not the test. Rent-qualified lines are different. Many require leases in place on all but one unit, so a fully vacant building fails that test. Signing a lease before you apply removes the question.
Living in one unit. If you occupy one unit, the property is treated as a primary residence, and the rules change. Leverage tiers, line sizes, and the ceiling all differ from the investment table above. Lendmire’s piece How to Qualify for an Investment Property HELOC on a Fourplex When You Live in One Unit covers that boundary in detail.
Opening the line while it is still your home. Some owners open a line while the property is still their residence, planning to convert it to a rental later. The CFPB’s HELOC booklet warns that renting your home may be prohibited under the terms of the line. Occupancy at application drives the lane, and a later change can breach the agreement. Treat this as a risk to review with the lender, not a workaround.
Geography. Lendmire places home equity lines in 16 full-service states, which is narrower than its DSCR footprint. Confirm the property’s state before you spend time on documents.
One practitioner pattern is worth knowing. Files with one unit vacant often stall for reasons unrelated to the vacancy: the title sits in an entity, the first mortgage is too large relative to value, or the score lands just under 700. The empty unit gets blamed because it is the visible oddity. Checking title, equity, and credit first, in that order, saves a credit pull on a file that was never going to fit.
Carrying the Building While a Unit Sits Empty
A line does not pause when a unit empties. The first mortgage, the line payment, taxes, and insurance all continue. For this reason, many lenders look at reserves on investment files, and reserve rules vary by lender, leverage, and loan size.
Plan the carry before you apply. Count how many months you can cover the full obligation on the building with one unit producing nothing. Include the line’s payment at a high draw, since that is how it is qualified. A borrower who relies on the line’s proceeds to pay the line’s own payments is borrowing against the problem.
Use the money for something that produces income or lowers risk. Common uses include rent-ready work on the empty unit, a down payment on the next rental, or paying off higher-cost debt.
When a DSCR Cash-Out Fits Better
A line suits an investor who wants a small, flexible pool of capital and has a strong personal profile. A DSCR cash-out refinance suits a different borrower: someone who wants a larger sum, holds title in an LLC, or has income that does not document cleanly.
On a cash-out refinance of a standard rental, leverage tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. Credit floors start at 620 in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers. That brings the vacancy back into the picture, since the coverage ratio counts rent.
For the full picture, see Lendmire’s complete DSCR loans guide. If you want to compare lines for a building with a vacancy specifically, Lendmire also wrote about which HELOC program fits when one unit is vacant.
What the Decision Looks Like in Practice
Work through these questions in order. Stop at the first no.
1. Is the property in your name or a revocable living trust? If not, plan a vesting change or move to a DSCR cash-out. 2. Is your score at or above 700? If not, the investment line is out, and a DSCR file is worth a look. 3. Does the first mortgage leave room under 70% CLTV? If not, the line is too thin to be worth the credit pull. 4. Does your DTI stay under 50% when tested on the full draw? If not, a smaller line will not fix it, because the test uses the maximum draw. 5. Can you carry the building through the vacancy? If not, lease the unit first or build reserves before you draw.
If you pass all five, the empty unit is a scheduling issue, not an underwriting issue. If you fail the first or the second, the question is not about the vacancy at all.

Draw period: the stretch when you can take money from the line, followed by a repayment period when you pay it back.
Combined loan-to-value (CLTV): your first mortgage plus the new line, divided by the property’s value.
Debt-to-income ratio (DTI): your monthly debt payments divided by your monthly income.
DSCR: debt service coverage ratio, which divides the property’s monthly rent by its full monthly obligation.
Rent schedule: the appraiser’s estimate of market rent, documented on an income-based form.
Vesting: the way ownership is recorded on the deed, such as an individual, a trust, or an LLC.
Frequently Asked Questions
Does one vacant unit disqualify me from an investment property HELOC?
Not by itself on a personal-credit line. The lender tests credit, DTI, and CLTV, and rent is not the qualifying income in the network’s investment line. On a rent-qualified line, one vacant unit may be allowed, but the occupied units must carry the coverage.
Can projected rent on the empty unit count?
It depends on the lender. A personal-credit line may count a discounted share of rent or none at all. A rent-qualified line typically wants leases on the occupied units and gives little or no credit to an empty one. On DSCR purchase programs, a rent-ready vacant property’s market rent can count, but that is a different product.
What if I plan to renovate the empty unit?
A unit under renovation may fail the property-condition review, and it produces no rent while the work continues. Finish the work, get the unit rent-ready, and lease it before you apply if you can. Rent-ready makes a cleaner file than an open project.
Can my LLC take the line?
No. The network’s investment line requires title in the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A DSCR cash-out is the usual alternative for entity-held rentals, depending on program guidelines.
How much can I borrow on an investment property?
Up to 70% CLTV on an investment property, with a maximum line of $500,000, subject to lender guidelines and full file review. A 700 credit score is the floor. Your actual line depends on your first mortgage balance, the property value, and your DTI.
