How to Qualify for a HELOC in a High-Rise With a Commercial Floor

The Quick Read: To qualify, your unit must be a residential condo, the building must read as a residential project rather than a mixed-use commercial property, and you must clear the borrower tests for credit, combined loan-to-value, debt-to-income, and title, with leverage depending on whether the home is a primary residence, second home, or investment property. A commercial floor does not make your unit commercial. It does put the whole building under review.

• The line is secured by your unit, but the lender also reviews the building’s commercial share, budget, reserves, insurance, and litigation.
• On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit score.
• On a primary residence or second home, the ceiling reaches 90% CLTV, and only at a 720-or-better credit profile.
• Non-warrantable condos are eligible. Condotels, co-ops, and commercial or mixed-use collateral are not.
• Strong credit and equity cannot rescue a building the lender will not accept, so check the building first.

What Is Actually Being Reviewed?

Two things get reviewed: you and the building. Borrowers tend to prepare for the first and can be surprised by the second.

A home equity line of credit (HELOC) is a revolving line secured by a specific property. In a high-rise, that property is one condo unit. The lender looks at your credit, your debt load, and how much equity you have. It then looks at the project around the unit, because the unit’s value depends on the health of the building.

A commercial floor matters at the project level. A tower with a ground-floor restaurant and a few retail suites still reads as a residential building. A tower where large shares of the space are retail, office, or hotel-style operations starts to read as mixed-use. That label is a problem, because mixed-use and commercial collateral are not eligible on the lines Lendmire places through its wholesale network.

Your unit stays residential either way. The question is whether the building around it still looks like a residential project to the reviewer.

Step by Step: How Underwriting Treats It

Step 1: Confirm the collateral. The unit must be a residential condo. Across the network, condominiums are eligible, including non-warrantable projects. A retail or office unit, a unit zoned commercial or mixed-use, or a condotel unit is a different product and falls outside these lines.

Step 2: Confirm title and vesting. Title (the legal form in which you own the property) must sit with you as an individual or in your revocable living trust. An LLC, a corporation, a partnership, or an irrevocable, blind, or land trust cannot hold title on these lines. This is the sharpest difference from a DSCR loan. If your unit is already deeded to an LLC, you either change the vesting or look at a DSCR cash-out refinance instead.

Step 3: Run the borrower tests. The program floor is a 600 credit score, though second homes start at 640 and investment properties at 700. Debt-to-income (DTI) tops out at 50%, but profiles from 600 to 679 are held to 45%, so anything higher requires a 680 minimum. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Step 4: Match leverage to occupancy. The table below shows the ceilings. Every figure is subject to lender guidelines and full file review.

CLTV means combined loan-to-value: your first mortgage plus the new line, divided by the property’s value. Lower credit tiers carry lower ceilings on primary residences and second homes, so the 90% figure is the top of the ladder, not the middle. Investment lines have no tier above 70%.

Step 5: Clear the project review. The lender asks the HOA for the budget, reserve study, delinquency data, insurance declarations, litigation status, and the commercial-space percentage. You gather these through your management office, so start early.

Step 6: Valuation. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation, and you may request a full appraisal in any case. Every line above $500,000 requires a full appraisal. NerdWallet notes that investment-property lines in the wider market can also call for multiple appraisals to confirm value.

Step 7: Close with a draw. At least 75% of the line is drawn at closing.

Why the Commercial Share Gets Measured Differently

No published rule sets one commercial-space cap for non-agency home equity lines. Lenders set their own comfort level, and that is why one lender may accept a building another declines. Anyone quoting a single universal percentage for these lines is guessing.

The number you may have heard is 35%. It comes from the agency condo rules used for conventional loans, which are contrast only here. Freddie Mac’s guide treats a project as having excessive commercial space when it passes 35%. It counts above-grade and below-grade square footage, includes retail, restaurants, and hotel or rental-apartment space, and excludes commercial parking. That standard governs agency loans. It does not set the limit on these lines.

The useful takeaway is the method, not the number. How a lender counts changes the result. A tower with a retail podium, hotel floors, and a garage can look very different depending on whether parking counts and whether the lender measures against the project or the whole building. Ask the lender which method it uses before you pay for anything.

Which Structures Exist?

Across the network, the line is a standalone product in first or second lien position. Lendmire places files with two wholesale programs: a higher-leverage program and a longer-runway program. Some terms differ between them, so each figure applies only within its own program.

Primary residences and second homes can choose between two draw structures. The first is a 3-year interest-only draw followed by a 17-year fully amortizing repayment. Tennessee shortens both, to a 3-year draw and 12-year repayment on the first and a 5-year draw and 10-year repayment on the second. Investment lines run the 5-year draw and 25-year repayment structure only.

The line stays variable through both the draw period and the repayment period. It never converts to fixed. The Consumer Financial Protection Bureau describes the same pattern: an open-end line you can borrow against repeatedly, a draw period, then a repayment period, with monthly payments often significantly higher once repayment begins. Model that jump before you rely on the line for a rental’s cash flow.

Line sizes run from $25,000 to $750,000. A line above $500,000 is primary-residence only. It requires a credit profile of 700 or better (720 on the longer-runway program), caps at 75% CLTV, and requires a full appraisal. So an investor with a rental condo is working inside a $500,000 ceiling no matter how much equity the unit holds.

Two more limits apply. A borrower may hold only three lines, and an owner of more than 15 financed properties is not eligible. Bankruptcy needs 4 years of seasoning from discharge or dismissal.

Where the General Rule Breaks

The rules above hold for a typical tower. These edge cases are where files go sideways.

The denominator problem. The same building can pass under one counting method and fail under another. Parking, hotel floors, and shared amenity space all move the percentage.

Hotel-style operations. A condotel is not eligible, whatever the percentage. If the building runs a rental pool, front desk, or hotel flag, expect a decline.

Live-work and mixed-use zoning. A unit zoned mixed-use or commercial is outside these programs. Eligibility follows the zoning, not how you use the space.

Non-warrantable does not mean no financing. A non-warrantable condo misses agency standards. The mortgage insurer Enact lists excessive commercial space (generally over 35%) among the triggers, alongside investor concentration and litigation. That status limits conventional financing, but non-warrantable condos are eligible on these lines. It can still affect resale, since non-warrantable units can be harder to sell or can sell at discounts.

Whole-building purchases and 5+ unit buildings. These are commercial lending, not a home equity line.

The sub-640 wrinkle. Condos are eligible in general, but a borrower under 640 is limited to single-family residences under the longer-runway program, so a condo unit would not fit at that score. Because second homes floor at 640 and investment properties at 700, this restriction reaches primary residences only.

Foreclosure history. Primary residences and second homes split here. One program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4. The other declines the history entirely, whatever its age. Investment files follow the 7-and-4-year path.

Run a Self-Check Before You Apply

Ask your management office these questions before any lender does.

• What share of the building is commercial, and does that count include parking and below-grade space?
• Does any part of the building operate as a hotel, a rental pool, or a short-term-rental program?
• What do the reserve study and current budget show?
• Are there open lawsuits against the association?
• How many owners are delinquent on dues?
• Does the insurance declaration cover the whole project?
• How many units are investor-owned?

If the answers point to a clean residential project with a modest retail footprint, your odds look better. If the building carries hotel operations or a large commercial share, expect friction. Better to learn that before paying for an appraisal.

What to Do If the Building or the Borrower Fails

First figure out which test failed. A borrower decline can be fixed with credit repair, lower leverage, or a change in how title is held. A building decline cannot be fixed by any change on your side.

If the building is the problem, a DSCR cash-out refinance is one alternative to consider. It works differently from a line of credit. A home equity line judges you and the building. A DSCR cash-out judges the property by whether its rent covers the monthly payment, so it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire’s complete DSCR loans guide walks through the full structure.

Leverage, seasoning, and score requirements on a DSCR cash-out vary by lender and program, so confirm them before you apply. Coverage of 1.00 is where select programs start, and a separate select-lender path accepts coverage below 1.00 with leverage and terms adjusted. LLC titling is possible, subject to lender program eligibility, which is the opposite of the home equity line. Clearing 1.00 does not mean positive cash flow, since repairs, vacancy, management, and utilities sit outside the calculation. The building’s commercial share still gets reviewed on a DSCR file, so the self-check above still applies.

Key Terms Defined

HELOC: A revolving credit line secured by a property, where you borrow against your equity as needed rather than taking one lump sum.

CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value.

Draw period: The early stretch when you can borrow from the line and pay interest only. After it ends, the repayment period begins.

Repayment period: The later stretch when you can no longer draw and the balance amortizes, so payments often rise.

Non-warrantable condo: A condo project that misses conventional agency standards, for example because of heavy commercial space, investor concentration, or litigation.

Vesting: The legal form in which title is held, such as in your own name or a revocable trust.

Project review: The lender’s check of the building itself, including the budget, reserves, insurance, litigation, and commercial share.

Next Step

If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. Lendmire is a broker that arranges financing through select wholesale partners, and it is not the lender. Every figure here is subject to lender guidelines and full file review, and nothing here is a commitment to lend.

A tower’s commercial floor rarely decides the loan on its own, but the HOA’s answers to a few plain questions often do.
