The Quick Read: Qualifying starts with the rent figure the lender counts, and a below-market lease usually sets that figure. Across the wholesale network, programs generally count the lesser of the signed lease and the appraiser’s market rent, so a low lease becomes the ceiling in the coverage ratio. Through select programs, a DSCR HELOC on a rental requires a minimum 1.10x coverage on a stress payment over the whole line, subject to underwriting.
- The lease is the rent whenever it sits below market. The appraiser’s market rent does not drop to match your tenant.
- A lease above market does not help. It is capped at market, unless the receipts back it up.
- The test runs on the full credit limit, not just the amount drawn at closing.
- A second lien needs a 720 score and tops out at 70% CLTV. A first lien starts at a 700 score.
- Fixing the lease before the valuation is often the biggest lever, where local rules allow it.
What a DSCR HELOC Is (and Why the Label Misleads)
A DSCR HELOC is a revolving line secured by a rental you keep. It is written as a standalone second lien behind your existing first mortgage, or as a standalone first lien on a paid-off rental. Rent qualifies it. Your tax returns, pay stubs and personal debt-to-income ratio are not part of the calculation.
The label causes confusion. Some products sold as investment-property HELOCs are underwritten on the owner’s personal income, and a lease matters very little there. Others are rent-qualified. This article covers the rent-qualified kind. Before you build a plan around a product, ask which test it runs.
Availability is also narrower than the label suggests. A dedicated rent-qualified second lien is a niche, and most equity access on a rental happens through a DSCR cash-out refinance that replaces the first mortgage. This line is offered only in a limited set of states under Lendmire’s consumer licensing, and Lendmire arranges it as a broker through a wholesale lender.
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. Scotsman Guide describes the product as non-QM and focused on whether the property can cover the payment. For the full product map, see the complete DSCR loans guide.
Which Rent Does the Lender Count?
The lesser of the lease and the appraiser’s market rent counts. That is the rule on this line, and most programs we place files with work the same way. A few lenders lean on actual rent instead, which is why lender choice matters on a below-market file.
| Lease situation | Rent counted | Effect on coverage |
|---|---|---|
| Lease below market | The lease | Ratio drops one-for-one |
| Lease above market | Market rent (or lease with 3 months of receipts) | No gain from the excess |
| Lease equals market | Either | Clean read |
| Month-to-month or expired | Often market rent, program decides | Can help a low-paying tenant |
| Vacant | Not eligible on this line | A lease in place is required |
Market rent comes from the appraiser’s rent schedule. Fannie Mae Form 1007 is an appraiser attachment that estimates monthly market rent for a single-family investment property from comparable rentals. Two to four units use the multi-unit rent schedule. These forms serve only as rent documents here. They do not make the loan an agency loan.
McKissock notes that the form documents monthly rent and can be used alongside lease agreements on a refinance. It also says deciding how income is used belongs to the lender, not the appraiser. The appraiser does not know what your tenant pays. A cheap lease does not pull market rent down.
Why a Below-Market Lease Hurts More on a Line
The line’s qualifying payment is a stress payment. It is a fully amortizing payment on the entire credit limit, tested at a stressed rate above the start rate. The test ignores how much you draw. A $300,000 line is tested as if fully drawn, even if only part of it is drawn at closing.
Taxes and insurance do not fall when rent does. So the ratio moves with rent while the obligation stays put. Coverage that clears comfortably on market rent can slip toward the 1.10x floor on a lease 10% to 15% under market. The maximum line shrinks by more than the percentage rent gap, because the lease is the binding limit rather than value.
Whether the first-mortgage payment counts toward the qualifying payment on a second lien depends on the lender’s own coverage calculation, so confirm that treatment before you model the deal. Don’t assume it works one way or the other, and ask for the lender’s method up front so your numbers match theirs.
The general formula is monthly rent divided by the monthly obligation: principal, interest, taxes, insurance and association dues. Scotsman Guide explains the same ratio and notes that terms vary by lender.
A Before-and-After Read
Take a single-unit example. Say the appraiser’s market rent supports coverage near 1.25x on the full line. The tenant’s legacy lease sits about 15% under that. Coverage lands near 1.06x, below the 1.10x floor. The same property with a signed renewal at documented market rent returns to about 1.25x.
Nothing about the property, the equity or the credit changed. Only the lease did. That is why sequence matters. These ratios are illustrative, and the lender’s own calculation governs.
Below 1.10x, a few paths exist. Select lenders in the network will review sub-1.00 coverage, but leverage and terms adjust. A smaller line lowers the stress payment. None of these is a promise.
Special Lease Situations
Month-to-month, expired or no written lease. Underwriting often substitutes market rent when little lease term remains, which can help a below-market tenant. This line requires a lease in place, so a signed renewal is the safer fix.
Multi-unit. Each unit counts at the lower of lease or market. An above-market unit does not offset a below-market one. A two-to-four-unit property may have at most 1 vacant unit.
Family or related-party tenants. Some programs review these more closely or exclude them. Arm’s-length evidence helps: a written lease, bank records of payment and a deposit on file.
Short-term rentals. Form 1007 documents monthly rent only. Multiplying a nightly rate by 30 is not supported. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Subsidized or regulated rent. Program treatment varies, and contract rent often stays the number. Ask before you assume the appraisal rent will apply.
How to Improve the File, in Order
1. Read the lease. Confirm the rent, the term, the renewal clause and any option to extend at a set price.
2. Check the first mortgage. Look at the documents before assuming a second lien is allowed.
3. Get a rent opinion early. A rent schedule shows the gap before you commit. If the lease is already at market, stop here.
4. Decide whether to renew. A renewal at market, where local rules allow it, closes the gap. Do not pressure a tenant. Notice rules and rent limits vary, and a forced buyout can create its own legal exposure.
5. Paper it. Get the signed renewal in hand before the valuation, not after. Underwriting does not credit a future increase before it takes effect.
6. Apply once the new lease is documented. Or wait until the old lease ends.
7. Right-size the line. If coverage is still tight, a smaller limit lowers the stress payment.
Inflating or inventing rent without appraisal support is misrepresentation. Don’t.
What the File Needs
- The signed lease, plus proof the rent is actually paid
- For a new lease, the deposit and first month’s rent
- The valuation: lines to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal; larger lines need a full interior appraisal. Appraisal waivers are not accepted.
- Title: a full title policy on a first lien and on second liens above $400,000
- LLC documents if vested in an entity, with members signing as guarantors, per lender program requirements
- Six months of ownership and seasoning on a purchase or refinance
No reserves or cash to close are required under the program. Underwriting still applies.
Key Terms Defined
In-place lease: The signed rental agreement now in effect on the property.
Market rent: The appraiser’s estimate of what the unit would rent for today, from comparable rentals.
Lower-of rule: The convention of counting the lesser of the lease and market rent.
CLTV: Combined loan-to-value, meaning the first mortgage balance plus the new line, divided by value.
Stress payment: The qualifying payment on the full credit limit, used only to test coverage.
Second lien: A loan that sits behind the first mortgage, which stays in place.
Where the Line Fits Against the Alternatives
| Structure | First mortgage | Lease matters |
|---|---|---|
| DSCR HELOC, second lien | Stays in place | Yes, sets the rent |
| DSCR HELOC, first lien | None on the rental | Yes, sets the rent |
| DSCR cash-out refinance | Replaced | Yes, lower-of rule |
A line suits an owner who wants to keep the first mortgage. A cash-out refinance suits an owner who needs more room or a different leverage tier.
Where the Rules Break
Not every property qualifies. Rural-designated property, condotels, row homes, leaseholds, land trusts and age-restricted communities are outside the line. A property listed for sale in the prior two months is out. A declining-market flag lowers the ceiling 5 points. Borrowers must be US citizens, permanent residents or non-permanent residents with a Social Security number.
Leverage figures are ceilings, not offers. A second lien reaches 70% CLTV at a 720 score or better, on lines up to $500,000. A first lien reaches 75% LTV at 740 or better, 70% from 700 to 739, and 65% on lines above $500,000, up to $1,000,000. All of it is subject to underwriting. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Some DSCR files get tripped up by the rent line before anything else. Coverage pencils on the asking rent or the renewal the owner expects, then drops once the lease and the rent schedule come back. Run the lower figure first.
Frequently Asked Questions
Does a below-market lease disqualify a DSCR HELOC?
Not automatically. It lowers the rent in the ratio, which can pull coverage under the 1.10x minimum or shrink the line. A renewal at market, a smaller line, or a different structure may fix it, subject to underwriting.
Will the appraiser adjust market rent for my tenant’s low lease?
No. The appraiser estimates market rent from comparable rentals. The lender then compares that to the lease and counts the lesser.
Does a lease above market raise my coverage?
No. The excess is capped at market rent, unless the program accepts the higher lease with three months of receipts.
Can I use the LLC that owns the rental?
Yes, on investment property, subject to program terms. Members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument.
What if the first mortgage lender restricts a second lien?
Check the first-mortgage documents before applying. If a second lien is not allowed, a first-lien cash-out refinance may be the practical path.
