The Quick Read: A market-rent study does not replace a lease on a DSCR HELOC. Across the wholesale network Lendmire works with, the line requires a lease in place, so a fully vacant rental does not qualify for it, even though that same market-rent study can carry a DSCR purchase or cash-out file.
- A DSCR HELOC is a revolving line on a rental, written as a second lien or a first lien.
- Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market.
- A two-to-four-unit property may have at most one vacant unit.
- A vacant rental has other routes: leasing it first, taking a DSCR cash-out refinance, or using a bridge loan followed by a DSCR refinance.
- Which program fits depends on the property, the rent, the equity, the credit profile, and your goals.
Investors often assume the market-rent study works everywhere. It works on some DSCR products, and this is a place where it does not. The rest of this piece shows why, what the underwriting does step by step, and what your options look like.
Key Terms Defined
DSCR (debt service coverage ratio): Gross monthly rent divided by the monthly payment the lender tests against. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Market-rent study: The appraiser’s opinion of what the property would rent for, built from comparable rentals. For a single-family home it is usually Form 1007, the rent schedule attached to the appraisal.
Form 1025: The appraisal report designed for two-to-four-unit properties. It plays the role the 1007 plays for one unit.
Stress payment: A fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is a test number, not what you pay.
Seasoning: The waiting period a lender wants after you buy or refinance a property.
Lien position: Where a loan stands in line for repayment. A second lien sits behind the first mortgage. A first lien stands alone.
What a DSCR HELOC Actually Is
A DSCR HELOC is a revolving line of credit secured by a non-owner-occupied one-to-four-unit rental you keep. It is written as a standalone second lien behind the first mortgage you keep, or as a standalone first lien on a rental with no mortgage. It is never a line on your own home or a second home.
The rent qualifies the line. The file carries no traditional personal-income documentation, W-2s, pay stubs, or personal debt-to-income calculation. In plain terms, it is reviewed on the rental’s income, subject to lender guidelines. The rent, the lease, the credit report, and the valuation are all documented.
Vesting the property in an LLC is allowed on this program, subject to lender program eligibility. The members sign as guarantors. If the title holder is not a borrower, that person signs a non-borrowing owner acknowledgment.
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. For the full picture across products, see Lendmire’s complete DSCR loans guide.
Why Does a Market-Rent Study Carry Some Loans but Not This One?
On a DSCR purchase or cash-out refinance, a vacant, rent-ready property is typically underwritten on the appraiser’s market rent alone. Nothing else exists to count. On a DSCR HELOC, a lease in place is required, so the study cannot stand in for it.
That is the main fork. Here is how the products compare on a vacant rental:
| Product | Vacant rental | Rent basis |
|---|---|---|
| DSCR purchase | Typically workable if rent-ready | Market rent |
| DSCR cash-out refinance | Typically run on market rent | Market rent |
| DSCR HELOC | Lease in place required | Lesser of lease and market rent |
| Standard investment HELOC | Rent not underwritten | Personal income |
The standard investment HELOC row is a different program with its own rules. It is reviewed on personal income, so vacancy is not the issue there. Programs vary by lender, so confirm how a given lender treats vacancy before you order anything.
What Is the Market-Rent Study, Exactly?
The study is the appraiser’s market-rent opinion. For a one-unit property, the appraiser completes the single-family comparable rent schedule. Its own instructions say the lender uses the form to obtain market rent from the appraiser, and the appraiser attaches it to the appraisal.
The form is built on three comparable rentals. It produces an indicated monthly market rent, and the appraiser comments on rent ranges, vacancy, and trends. For two-to-four units, the appraisal report is a different form, 1025, which is designed for that property size.
These forms come from the agency world. DSCR loans are not agency loans. They borrow the form names, and the program rules come from each lender’s own guidelines.
One caution if you plan nightly rentals. Fannie Mae’s appraiser guidance says the rent schedule was not designed for short-term rentals. The appraiser must support market rent with comparables leased monthly. Multiplying a nightly rate by 30 is not acceptable.
How Underwriting Treats a DSCR HELOC, Step by Step
Here is the sequence a file moves through, based on the programs in the wholesale network.
1. Product and collateral. The property must be a non-owner-occupied one-to-four-unit rental. Your own home and second homes are out.
2. Lease gate. A lease must be in place. A two-to-four-unit property may have at most one vacant unit.
3. Rent evidence. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market.
4. Coverage test. The minimum DSCR is 1.10x. Gross monthly rent is divided by a qualifying payment, which is principal and interest on the entire credit limit at the stress rate. Taxes and insurance are not part of that payment. On a second lien, confirm on the file how the lender treats the first-mortgage payment; the lender’s own calculation governs. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
5. Seasoning and listing history. A rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date). A property listed for sale in the prior 2 months is also not eligible.
6. Valuation. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
All of this is subject to underwriting and select program guidelines.
What Leverage and Line Terms Look Like
Leverage differs by lien position. On a second lien, combined loan-to-value (the first mortgage balance plus the new line, divided by value) reaches 70% CLTV at a 720 credit score or better, on lines of $50,000 to $500,000. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
On a first lien for a rental with no mortgage, loan-to-value reaches 75% LTV at 740 or better and 70% LTV from 700 to 739, on lines up to $500,000. Larger first-lien lines, to $1,000,000, are capped at 65% LTV at 720 or better. These are ceilings, not offers. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
The line itself has a 5-year interest-only draw period, then a 25-year repayment period, for a 30-year maturity. The rate is variable. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each.
On credit, expect no 30-day mortgage late in the last 12 months and 48 months since a bankruptcy, foreclosure, short sale, or deed in lieu. No reserves are required. Exposure is capped at 5 loans or $2,500,000 per borrower with the program. Rural property, condotels, row homes, and leaseholds fall outside it.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Borrowers must be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number.
Where the Rules Bend: Edge Cases
Partially vacant two-to-four units. One vacant unit is allowed on the HELOC. A purchase or cash-out file can credit a vacant unit at market rent and an occupied unit at its lease.
Lease above market. On the HELOC, the excess counts only when three months of receipts support it. On purchase-type files, the figure is generally capped at market rent, which is a lender convention rather than a federal rule.
Lease below market. The lease figure holds the ratio down.
Rehab or not rent-ready. A property that cannot be leased today does not fit this line. One route is a bridge loan first, then a refinance into a DSCR loan once the property is stabilized.
LLC title. An LLC-held rental may need a vesting change or a different product, depending on the program.
Funding a purchase with a line. A line on an owned, leased rental can fund an offer on another property, with a DSCR cash-out on the new property as the exit. The target property has no rent yet, so it cannot carry its own line.
If Your Rental Is Vacant: The Decision
Four routes are open, including the standard HELOC that the opening summary leaves out.
Lease it first, then apply. This is the cleanest route if the property is rent-ready. Once a tenant is in place and the 6-month clocks have run, the HELOC comes into play. Leasing time and seasoning both affect your timing, so plan the order.
DSCR cash-out refinance on market rent. It can run on the appraiser’s number alone. The tradeoff is that it resets your first mortgage rather than adding a line behind it.
A standard investment HELOC. Because it is reviewed on personal income, rent is not underwritten and a vacant unit is treated like a leased one. That also means opening the personal income file, which a DSCR line avoids.
Bridge loan, then DSCR refinance. This suits a property that needs work before it can be leased.
Which fits depends on the property, the rent, the equity, your credit profile, and combined leverage. A broker that shops multiple wholesale lenders can match the scenario to the program, and the right program for your situation can differ from the one you assumed.
How to Prepare the Rent Study
Whichever route you pick, a few habits help.
Settle the rent basis before you order the appraisal. Ordering first, then learning the lender uses a different rent figure, wastes the step.
Make the property rent-ready. Condition drives how the appraiser’s comparables line up.
Expect the comp set to drive the number. On a vacant file the rent opinion is the only rent figure in play, so thin comparables can hurt the result. If the number comes in low, ask whether additional comparables can be considered, or whether a smaller line still clears coverage.
Ask three questions up front: which rent does the DSCR calculation use, is the appraisal as-is or subject to completion, and do I need a lease?
Passing the Ratio vs. Actually Cash Flowing
The qualifying payment is a stress number. It assumes the whole line is drawn and fully amortizing at a higher start rate. Your real payment is interest-only on the drawn balance during the draw period.
So a file can clear 1.10x on paper and still run tight in real life, or the reverse. Test the ratio on the full line before you apply. Divide the rent the lender will count, the lesser of lease and market rent, by a full-line stress payment, unless three months of rent receipts support a lease above market. Then separately ask whether the property cash flows on what you actually draw. Both matter, and they are different questions.
Frequently Asked Questions
Can a completely vacant rental get a DSCR HELOC?
Not on this program. A lease in place is required, and a market-rent study cannot substitute for it. A two-to-four-unit property may carry one vacant unit, but at least the rest must be leased. A vacant rental may fit a DSCR cash-out refinance on market rent instead.
How long must I own the property first?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date). A property listed for sale in the prior 2 months is also ineligible.
Does an above-market lease raise my ratio?
Only with support. Unless three months of rent receipts support a lease above market, the lease excess is ignored.
Does the market-rent study work for short-stay or nightly rentals?
No. The rent schedule requires comparables leased monthly, and nightly rates multiplied out are not acceptable.
Can I use an LLC?
Vesting in an LLC is allowed on this program for investment property, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
