The Quick Read: Usually yes, if you own a residential condo unit in the tower. The commercial floor gets reviewed as part of the building, while the unit’s rent qualifies the line. Usually not, if the collateral is the commercial unit itself or a whole mixed-use building. A DSCR HELOC is a home equity line on a rental, qualified on the property’s rent instead of your personal income.
- Two separate reviews apply: one on you and the rent, one on the building.
- The commercial floor touches only the building review.
- A strong borrower cannot rescue a building the lender will not accept.
- A commercial unit, a mixed-use building, and a condotel are outside this program.
- Everything below is subject to underwriting and lender guidelines. This is not a commitment to lend.
Two Gates: Your Unit and the Building
Every condo file passes two gates, and the commercial floor only matters at the second one. The first gate is the unit and the borrower: rent, lease, credit, equity. The second is the project: what else is in the building and how it is run.
| Gate | What gets reviewed | Does the commercial floor matter? |
|---|---|---|
| Unit and borrower | Rent, lease, credit, combined leverage | No |
| Building | Commercial share, investor mix, litigation, dues, insurance | Yes |
Say you own a unit on the twentieth floor of a tower with a ground-floor retail podium. Your unit is a residential condo. The retail space below is a feature of the project. Lenders treat the first as the collateral and the second as a risk factor in the collateral’s surroundings.
That is why a retail podium does not disqualify you on sight. It also means a clean rent number does not finish the job. Across Lendmire’s wholesale network, the building review is where most condo files in mixed towers either clear or stall.
What Counts as Commercial Space?
Commercial space is any part of the project used for something other than housing, and lenders weigh it by how much of the building it takes up. Typical examples include ground-floor shops, restaurants, offices, medical suites, and street-level service businesses. Garage parking and building amenities are treated differently from lease-generating retail.
Two points trip people up. A tower is not mixed-use just because a coffee shop sits in the lobby. Mixed-use is a category, not a measurement, as National Condo Inspections puts it. The number that matters is the share, and that is the question the lender asks.
The second point: the share depends on how the lender counts it. Most programs start with square footage. Some also look at the income the commercial leases generate. Ask the lender which basis it uses before you assume your building passes.
How Lenders Measure the Commercial Share
Lenders divide non-residential space by total space, then compare that share to their own ceiling. There is no single ceiling for investor loans. Each program in the network sets its own, and the number can shift with the building’s other traits.
For contrast, take the agency world. The Fannie Mae Selling Guide caps commercial or mixed-use space at 35% of a condo project or its building, counting space above and below grade, and it allows commercial parking to be excluded. DSCR lines are not agency products, so that figure does not govern your file. It does explain why buildings get tagged non-warrantable.
Non-warrantable is a label, not a denial. A condo project that fails agency tests, for reasons such as heavy commercial use, is simply reviewed under a different rulebook. Enact, a private mortgage insurer, lists mixed-use or excessive commercial space, generally above 35%, among the common triggers.
In this program, non-warrantable condos are eligible through select lenders, but at a lower ceiling than warrantable ones. For a second-lien line on a non-owner-occupied rental, the ceiling stays at 70% combined loan-to-value (CLTV) at a 720 score or better, subject to underwriting. Non-warrantable status never adds leverage.
Here is the part no marketing page tells you. Programs do not publish one commercial-share cutoff for lines. Some lenders will accept a modest podium. Others will decline a building at a lower share if investor concentration or litigation sits on top. The only reliable test is a project review on your building.
How to Find Your Building’s Numbers
Get the building’s own documents before you plan a deal around a line. The property manager or the HOA can usually supply everything below. Do this before you pay for an appraisal.
1. Request the condo questionnaire. It surfaces commercial space, investor concentration, litigation, delinquent dues, and insurance problems in one document.
2. Ask for the square-footage breakdown. You want residential, commercial, parking, and amenity space listed separately.
3. Read the declaration and budget. They show how the commercial units are governed and who pays for what.
4. Check for single-entity ownership. One owner holding a large block of units is a red flag on its own.
5. Find out whether the commercial unit is leased or vacant. A lender will care about stability, not just size.
6. Ask about any hotel-style features. A front desk, a rental pool, or condotel operations can end the review outright.
If the manager will not give you the commercial share, treat that as an answer about how smooth the review will be.
What the Line Itself Requires
Once the building passes, the rest is a standard DSCR HELOC file. Everything below is a ceiling or floor that applies through select programs, subject to underwriting.
The structure first. This is a standalone second lien behind the first mortgage you keep. On a rental with no mortgage, it can be a standalone first lien. It is never closed alongside a purchase, and it is never offered on your own home.
Qualification runs on rent. The rent has to cover a stress payment on the full line at a minimum DSCR (debt-service coverage ratio) of 1.10x. Rent is the lesser of the appraiser’s market-rent estimate (Form 1007) or the lease, and a lease in place is required. The lender’s coverage calculation governs, and condo dues are part of the carrying cost lenders weigh. No traditional personal-income documentation, W-2s, or pay stubs enter the picture. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
| Position | Leverage ceiling | Credit score |
|---|---|---|
| Second lien, non-owner-occupied rental | 70% CLTV | 720 or better |
| First lien, rental with no mortgage | 75% LTV | 740 or better |
| First lien, rental with no mortgage | 70% LTV | 700 to 739 |
| First lien, line above $500,000 | 65% LTV | 720 or better |
Combined loan-to-value counts the first mortgage balance plus the new line against the property’s value. Second-lien lines run from $50,000 to $500,000. First-lien lines run to $1,000,000.
Line mechanics. At least 80% of the line is drawn at closing, with later draws of at least $5,000. A 5-year interest-only draw period is followed by a 25-year repayment period, and the loan matures at 30 years. The rate is variable.
Valuation. Lines 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.
Seasoning and exposure. You need six months of ownership, and a rental bought or refinanced inside the last six months is not eligible. No reserves are required. A borrower can have up to five loans or $2,500,000 with the program.
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. The complete DSCR loans guide covers the ratio math in depth.
DSCR HELOC or DSCR Cash-Out Refinance?
For a unit in a mixed tower, a cash-out refinance is often easier to place than a revolving line. Both draw on equity. They are different loans with different supply.
A DSCR HELOC leaves your first mortgage alone and adds a second lien. A cash-out refinance replaces the first mortgage with a larger one. If your current first mortgage is something you want to keep, the line wins. If you would refinance anyway, the cash-out may open more lender options.
The market also muddies the labels. Many products sold as DSCR HELOCs are really closed-end second mortgages or first-lien cash-outs. Ask a plain question: is it revolving, and can I redraw after the first draw? Lenders offering true lines on investment property are a small group, and condo plus non-warrantable plus a line narrows the field further.
Title and Vesting
An LLC can hold the unit, subject to program terms. Vesting in your LLC is allowed on an investment property. The members sign as guarantors. If a title holder is not a borrower, that holder signs a non-borrowing owner acknowledgment and the security instrument.
Condo associations sometimes have rules about entity ownership. Check the declaration for restrictions on investor or LLC ownership before you structure the file.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.10x coverage ratio being the minimum (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Other Red Flags That Travel With Commercial Floors
Commercial space rarely arrives alone. Buildings with a retail podium often carry other traits the same lender will review at the same time.
- High investor concentration. Many rentals and few owner-occupants make a project riskier to a lender.
- One owner holding a block of units. Developers who keep unsold units create this situation.
- Litigation. Defect suits over a new tower are common and can stall a file.
- Delinquent dues. A building where many owners are behind on dues has a funding problem.
- Short-term rental activity or hotel-style operations. A condotel is not eligible in this program.
- Insurance issues at the project level. Commercial tenants in the podium raise use and coverage questions for the whole building.
Stacked issues are the real killer. A modest podium alone might pass. That same podium plus heavy investor concentration plus a lawsuit often pushes a building out of a lender’s range, even though each factor alone would not. Some lenders accept only a limited number of non-warrantable traits.
How Different Setups Play Out
The outcome turns on what you own and how large the commercial share is. Use this as a map, not a promise.
| Your situation | Likely outcome | Next step |
|---|---|---|
| Residential unit, small retail podium | Reviewable as a condo | Get questionnaire, run project review |
| Residential unit, large commercial share | Depends on lender overlays | Ask the lender for its share ceiling |
| Whole floor commercial in the tower | Building review gets harder | Check stacked issues first |
| You own the commercial unit | Outside this program | Look at commercial financing |
| Whole mixed-use building | Outside this program | Look at commercial financing |
Now a modeled example, with labeled assumptions and no sourced market data. Assume a one-unit rental on a mid-tower floor, leased at market, with rent clearing the 1.10x test with room to spare after dues. Your side of the file looks strong. The project review then finds a commercial share in the single digits to low teens and no litigation. The unit moves forward subject to underwriting.
Change one input. Same unit, same rent, but the building has a large commercial share and one owner holding a big block of units. Your coverage is unchanged, and the file can still stop. That is the two-gate model at work.
Does Federal Law Force Income Documentation on a HELOC?
No. A DSCR HELOC is reviewed on rent because of lender policy, not because a rule requires it. The federal ability-to-repay rule in Regulation Z does not apply to open-end home equity lines. Nothing in federal law forces W-2s onto a revolving line. Whether a product uses rent or personal income is a choice the lender makes.
That does not mean anything goes. The file still needs a lease, a credit report, a valuation, and title work. Only the personal-income verification changes.
Key Terms Defined
DSCR (debt-service coverage ratio): The property’s gross monthly rent divided by the monthly obligation the lender uses to test it.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value.
Non-warrantable condo: A condo project that fails agency eligibility tests, often for commercial space, investor concentration, or litigation.
Condo questionnaire: A form the association completes about the building’s finances, ownership mix, insurance, and legal issues.
Seasoning: The ownership period a lender requires before it will lend against a property. This program requires six months.
Condotel: A condo with hotel-style operations, such as a front desk or a rental pool. It is not eligible here.
If the Building Fails
A failed building review does not end your options, but it changes the product. Three paths are worth testing.
- Try a different lender. Commercial-share ceilings and overlays vary across the network, so a building that fails one program can pass another.
- Switch to a cash-out refinance. If the unit qualifies as a condo, that loan may be easier to place than a line.
- Look at commercial financing. If you own the commercial unit or the whole building, that is the right asset class for the loan.
Before you rely on a line to fund your next acquisition, get the questionnaire and the commercial square-footage breakdown first.
Tax treatment varies; consult a qualified professional.
Frequently Asked Questions
Does a ground-floor shop make my whole tower commercial?
No. A single retail space does not turn a residential tower into a commercial building. Lenders look at the share of total space the commercial use takes up, and they compare it to their own ceiling. A small podium is a project-review item, not an automatic denial.
Does the floor number of my unit matter?
Not for the commercial question. What matters is the share of the building that is commercial, not how high your unit sits. Lenders do look at whether the project has hotel-style features, which can make a tower ineligible regardless of floor.
Can my LLC hold the unit?
Yes, subject to program terms. Vesting in your LLC is allowed on an investment property, and the members sign as guarantors. Check the association’s declaration for limits on entity ownership.
Is there a universal commercial-space cap?
No. Agency programs use a fixed percentage, but DSCR lines are not agency products. Each lender in the network sets its own ceiling and overlays, and the building’s other traits can move it. The reliable answer comes from a project review on your specific building.
What if I own the commercial unit too?
Then the collateral changes. Commercial and mixed-use property is not offered in this program, and a commercial unit would need a commercial loan. If you own a residential unit in the same tower, the residential unit can still be reviewed on its own.
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. The program is offered through select lenders in the states where Lendmire holds consumer licensing. Lendmire is a broker, not a lender, and every file is underwritten individually. Reach the team at 828-256-2183.
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. In a mixed tower, the building’s commercial floor decides the file as often as the borrower does.
