The Quick Read: A residential condo unit in a high-rise with a commercial floor can often carry a DSCR HELOC. The line is secured by your unit and qualified on its rent, while the building gets a separate review. The program that fits best depends on the building, your credit, your first mortgage, and the line size you need.
- The unit is the collateral. A residential condo qualifies as collateral; a commercial unit, a live-work unit, or a whole mixed-use building does not.
- Rent has to cover a stress payment on the entire credit limit at 1.10x or better, subject to underwriting.
- A second lien reaches up to 70% combined loan-to-value at a 720 score or better, on lines up to $500,000.
- A commercial floor triggers closer building review, not an automatic decline.
- The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
What a DSCR HELOC Actually Is
A DSCR HELOC is a revolving line of credit on a rental you own. It is reviewed on the rental’s income, not yours. The “DSCR” part stands for debt service coverage ratio: gross monthly rent divided by the qualifying payment. No traditional personal-income documentation, W-2s, pay stubs, or personal income calculation are part of the review, subject to lender guidelines.
Two structures exist across the programs Lendmire places files with. The first is a standalone second lien behind the first mortgage you keep. That is the one most owners want, because a low-balance first mortgage stays untouched. The second is a standalone first lien on a rental with no mortgage.
It is never closed alongside a purchase. It is never a third lien. It is never placed on your own home or a second home. An LLC can hold title, subject to program terms, with the members signing as guarantors.
“DSCR HELOC” is a market label, not a standard product, so programs differ. That is why a broker who sees many lenders’ guidelines matters more than any single lender’s page.
Where the Commercial Floor Actually Matters
The commercial floor matters to the building review, not to the loan type. Two questions get answered separately: what you own, and what the building is. Mixing them up is a common mistake in this niche.
| What you own | What gets reviewed | Likely path |
|---|---|---|
| Residential unit in a mixed tower | Your rent, then the building | DSCR HELOC possible |
| Commercial unit in the tower | Commercial collateral | Not offered; commercial financing |
| Live-work unit zoned commercial | Mixed-use collateral | Not offered; commercial financing |
| Whole mixed-use building | Mixed-use collateral | Not offered; commercial financing |
| Residential unit held in an LLC | Same as the first row | Possible, subject to program terms |
Here’s the catch. Condos in hotel-style operation, called condotels, are also outside the program. A tower that rents floors by the night can fail on that point alone.
How Underwriting Treats Your File, Step by Step
Here is the sequence most files follow through a wholesale lender. Everything is subject to underwriting.
1. Collateral check. The property must be a non-owner-occupied rental, from one to four units. A single condo unit fits. Rural-designated property, row homes, leaseholds, and a property listed for sale in the prior two months do not.
2. Building review. Warrantable and non-warrantable condominiums are both eligible property types. A tower with a commercial floor often lands in non-warrantable territory. That draws closer scrutiny of the project, and the lender’s own review governs.
3. Rent coverage. Rent is the lesser of the appraiser’s market rent (the Form 1007 schedule) or your lease. A lease above market can count with three months of receipts. A lease in place is required.
4. The stress test. The qualifying payment is fully amortizing and sized on the entire credit limit at the start rate plus 2 percentage points. It is not sized on what you draw. Minimum coverage is 1.10x. On a condo, HOA dues belong in the monthly obligation. For a second lien, the lender’s coverage calculation governs how the first mortgage payment is treated.
5. Leverage. On a second lien, combined loan-to-value (CLTV) is the first mortgage balance plus the new line, divided by value. It tops out at 70% at 720 or better, on lines up to $500,000. Say the first mortgage already sits at half of value. A 70% CLTV leaves roughly 20% of value as the most the line could be.
6. Valuation. For lines up to $400,000, the file takes an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Above $400,000, a full interior appraisal is required, and on a condo that is typically the 1073 form. Appraisal waivers are not accepted.
7. Seasoning. 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).
No reserves and no cash to close are required. Credit history rules still apply: no 30-day late on a mortgage in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu.

How Commercial Share Gets Measured
Agency financing offers the best-known yardstick, and it is only a yardstick. Under Fannie Mae’s Selling Guide, no more than 35% of a condo project, or of the building that contains it, may be commercial or mixed-use space. The test counts space above and below grade. Separate residential and commercial associations do not remove commercial square footage from the count. Commercial parking facilities can be excluded.
That rule governs agency loans. DSCR loans are non-QM, so it does not bind a DSCR HELOC. Lenders in the network set their own standards, so a published percentage is a reference point, never a promise. A commonly cited summary of commercial-space limits across agency and government programs shows why a tower over the agency line gets pushed toward non-warrantable status.
How do you find your building’s real share? Ask the management office for three things: the association questionnaire, the current budget, and the declaration. Then ask for the square-footage split between residential and non-residential space. Whether commercial parking, gyms, and amenity space count differs by lender. Ask before you assume.
The Structures and Variations That Exist
Second lien versus first lien. Most tower owners still have a first mortgage, so the second-lien path is the usual fit. It needs a 720 score or better. A first lien on a paid-off rental starts at a 700 floor. First-lien loan-to-value (LTV) reaches 75% at 740 or better, and 70% from 700 to 739. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Line size. Lines start at $50,000. Second liens run to $500,000. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each.
Terms. The draw period is 5 years, interest-only on the drawn balance. A 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable. The pricing terms come with the lender’s HELOC disclosures.
Title. A first lien, and any second lien above $400,000, gets a full title policy. A smaller second lien gets an owner-and-encumbrance report.
Ceilings, not offers. These figures are maximums through select programs. A declining-market flag on the property lowers the ceiling by 5 points.
Where the General Rule Breaks
The unit is commercial or zoned for it. The answer flips to no. Commercial, mixed-use, and live-work collateral are outside the program.
A hotel-style tower. Condotel operations are excluded. A building that merely has retail downstairs is a different case from a building run like a hotel.
The first-mortgage holder objects. A second lien needs the first-lien terms to allow it. Have your first mortgage statement ready.
HOA dues run high. In a mixed-use tower, an association may share the cost of commercial areas. That is an inference, not a rule, but higher dues cut coverage and can pull a borderline file under 1.10x.
You want the line as a reserve fund. A poor idea. Most of the line is drawn at closing. The CFPB’s HELOC explainer notes that a lender can limit draws if the property’s value falls. Not ideal for emergency cash.
You are outside the borrower pool. US citizens, permanent residents, and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not. Exposure is capped at 5 loans or $2,500,000 per borrower with the program.
What “Best Program” Means Here
There is no single best lender or program for this property. The best program for your situation is the one that clears the gates in order. Run them in this sequence:
1. Is the unit residential, and is the building a warrantable or non-warrantable condo rather than a condotel? 2. Does rent, after HOA dues, clear 1.10x on the stress payment for the whole line? 3. Does your score support the lien position you need, 720 or better for a second lien? 4. Does combined leverage leave enough room, given your first mortgage balance? 5. Has the 6-month seasoning clearance been met?
A broker earns its keep at step one of that list. Lenders in the network read a mixed-use building differently, and one that balks at a building’s profile may not be the only path. Which wholesale lenders will write the file depends on the building, credit profile, leverage need, and the documents you can produce. Lendmire’s complete DSCR loans guide explains how the broader program family fits together.
If the building fails, the fallback is a DSCR cash-out refinance. It replaces your first mortgage rather than adding a lien behind it, so it only makes sense if you are comfortable giving up the existing first.
Key Terms Defined
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment. Here the minimum is 1.10x.
HELOC: a revolving line of credit secured by property. You draw against it and repay under set terms.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Non-warrantable condo: a condo project that falls outside agency eligibility, often because of commercial space, litigation, or investor concentration.
Mixed-use: a property combining residential and commercial space. As collateral, it is outside this program.
Seasoning: the waiting period since you bought or refinanced the rental.
Frequently Asked Questions
Does a ground-floor store or office floor in my tower automatically block a DSCR HELOC?
No. A commercial floor draws closer building review, but a non-warrantable status usually means scrutiny rather than an automatic decline. The decisive point is what you own. A residential unit can be eligible collateral; a commercial or live-work unit cannot.
Does the 35% commercial limit apply to my DSCR HELOC?
Not as a rule. That figure comes from agency financing and is useful as a reference point. Lenders in the network run their own project review, so ask your broker how a specific building would be read.
Can my LLC hold the unit?
Yes, subject to program terms. The members sign as guarantors, and the property must be an investment property. The line cannot be placed on an owner-occupied home.
Is the rent test run on what I draw or the full line?
The full line. The qualifying payment is built on the entire credit limit at a stress level, so a larger line demands more rent coverage even if you draw only part of it. Underwriting and the lender’s own calculation govern the final figure.
What if my building fails review?
The usual paths are a DSCR cash-out refinance, a different lender’s read of the same building, or, for commercial collateral, commercial financing. Reading the association documents before you apply tells you which path to expect.
Next Steps
If you are considering a home equity line on a rental property and want to see how the numbers work, Lendmire can help you compare DSCR HELOC options based on the property, the rent, the equity available, credit profile, combined leverage, and your goals. Lendmire is a mortgage broker, so it arranges the file through select wholesale lenders; it does not lend or approve, and nothing here is a commitment to lend. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
In a tower with a commercial floor, the building’s paperwork often decides the outcome before the rent does.
