The Quick Read: The right program for a unit in a mixed-use tower depends on whether you hold title personally, how much equity sits above your existing liens, and whether the building passes a lender’s project review. The commercial floor only affects the building review. It never changes your personal credit review.
- On the investment lines Lendmire arranges, the ceiling is 70% combined loan-to-value (CLTV), and the maximum line is $500,000.
- The minimum credit score is 700, and 720 buys no extra leverage on an investment line.
- The collateral must be a residential condo unit. Commercial and mixed-use property is not offered as collateral, but a residential unit inside a mixed-use building can qualify.
- Title must sit with you personally or in a revocable living trust, not an LLC.
- The line is underwritten on your credit and debt, not on the rent.
What Is an Investment Property HELOC, Really?
A home equity line of credit (HELOC) is a revolving loan secured by property. You borrow, repay, and borrow again during a set window. On a rental condo, the unit itself is the collateral.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Investment lines are a different product from DSCR loans. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC looks at you: your credit, your debt-to-income ratio (DTI), and your equity. Rent is not the test.
Lendmire is a mortgage broker, not a lender. It places these lines with select wholesale lenders in its network. Because it shops more than one lender, it can match a scenario to the program that fits. HELOC availability sits in 16 full-service states. That is narrower than the DSCR footprint of 41 markets, including Washington, D.C.
Nobody can hand you one best program for a tower with a commercial floor. The best program for your situation depends on your title, your equity, your credit, and your building. The rest of this article shows how each of those decides the outcome.
Does a Commercial Floor Change What You Are Pledging?
Usually it does not, because you pledge your unit, not the building. Owning a residential condo above a retail podium is different from owning the commercial space. Lenders treat these as separate collateral types.
| What you own | Eligible as collateral? | Next path |
|---|---|---|
| Residential unit above commercial space | Yes, as a condo, subject to building review | HELOC or DSCR cash-out |
| Commercial or retail unit | Not offered | Commercial financing |
| Whole mixed-use building | Not offered | Commercial financing |
| Condotel or hotel-style unit | Not offered | Ask a broker about other structures |
Condominiums, including non-warrantable ones, are eligible property types on this network. A non-warrantable condo is a unit in a project that fails the agency-style tests for conventional loans. A mixed-use tower often lands in that group.
The Two Reviews Every File Gets
Every file passes two separate tests. One looks at you. The other looks at the building. The commercial floor lives entirely in the second.
| Item | Borrower review | Building review |
|---|---|---|
| What it checks | Credit, DTI, title, equity | Commercial share, litigation, reserves, owner mix |
| Does the commercial floor matter? | No | Yes |
| Where documents come from | You | The association |
| Typical failure | Credit under 700, LLC title | Heavy commercial use, lawsuits, thin reserves |
Most investors prepare for the first review and get surprised by the second. Start the building review early, because it depends on paperwork you do not control.
How Underwriting Works, Step by Step
Here is the sequence a file follows from start to finish.
1. Confirm the collateral. The unit must be a residential condo. You must hold title as an individual or in a revocable living trust.
2. Identify lien position. The line is a standalone line in first or second lien position. It is first lien if the unit is free and clear, or if the line pays off the existing mortgage. It is second lien if a mortgage stays in place. Recording order on title decides position, not the product name.
3. Run the CLTV math. Take the unit’s value times 70%, subtract every existing lien, and the remainder is your maximum line. The $500,000 cap applies on top of that. If your liens already equal 60% of value, you have roughly 10% of value in headroom. If you recently financed the unit at high leverage, you may have none.
4. Check the borrower. The lender pulls credit and tests DTI. A 700 score is a hard floor with no tier beneath it. DTI runs up to 50%, and it is qualified on the interest-only payment calculated on the maximum draw.
5. Review the building. The lender looks at the commercial share, investor concentration, litigation, reserves, and rental rules. Association documents such as the condo questionnaire, budget, and insurance certificate feed this step.
6. Value the unit. Investment lines cap at $500,000, so they ordinarily run on an automated valuation with no traditional appraisal. A higher CLTV can trigger a secondary valuation. You can also request a full appraisal in any case, which is worth considering when a tower has few comparable sales.
7. Close the line. You draw at least 75% of the line at closing. The structure and risks come next.
A credit report must be no more than 90 days old at closing, and rescoring is not available. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year path for a foreclosure and a 4-year path for a deed-in-lieu, pre-foreclosure, or short sale.
What Counts as Commercial Space?
There is no single published cap that governs every lender for these lines. The number most people quote comes from the agency world, and it works as a benchmark, not a binding rule. Under the Fannie Mae Selling Guide, no more than 35% of a condo project, or of the building it sits in, may be commercial or mixed-use space. The count includes space above and below grade. It also counts commercial square footage when residential and commercial owners belong to separate associations. Rental apartments and hotels inside the project are classed as commercial too.
That agency math does not govern the lines Lendmire arranges. For your building, lenders in the network review the commercial share case by case. Lendmire does not publish a network-wide commercial-space percentage, so beware of anyone quoting one as universal.
How the space is counted matters as much as the total. Say a tower has ground-floor retail and a garage owned commercially. Counting only the retail gives one share. Counting the garage as well gives a higher one. Lenders can differ on those choices, and the association’s records usually settle the facts.
Reality also helps here. National Condo Inspections notes that most mixed-use residential buildings carry a commercial share in the single digits or low teens. A tower with one commercial floor is often far from any agency threshold.
Line Structure and Limits
Investment lines run one structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment period. The pricing floats through both periods and never converts to fixed. That is a real payment-risk difference from a fixed-rate cash-out.
The CFPB’s HELOC booklet describes a HELOC as a loan that lets you borrow, spend, and repay as you go, using your home as collateral. It also describes a draw period followed by a repayment period. Experian reports that a typical market draw period runs five to 10 years, followed by a 20-year repayment period. The network’s investment structure is 5 years interest-only plus 25 years amortizing, so do not blend the two sets of numbers.
Other limits to know:
- Lines run from $25,000 to $750,000 overall, but an investment line stops at $500,000. Anything above that is limited to primary residences.
- After closing, the minimum subsequent draw is $1,000 on most files.
- You can hold up to three lines in total, and you are not eligible if you own more than 15 financed properties.
- Single-family homes, 2-4 unit properties, PUDs, townhomes, and condos are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
Title and Vesting: The LLC Problem
Many investors hold rentals in an LLC. This product does not allow that. Title must be held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
If your unit is already deeded to an LLC, you have two options. You can retitle it to yourself or a revocable trust, which has its own legal and lender-consent considerations to discuss with an attorney. Or you can pursue a DSCR cash-out refinance instead. DSCR loans can often be made to LLC-titled borrowers, subject to lender program eligibility.
Where the General Rule Breaks
The general rule says a residential unit with a passing building is eligible. These cases bend it.
- A separately owned commercial floor. Agency-style counting still includes commercial space owned by a different entity. Network lenders may view it differently, so ask early.
- Rental or hotel use in the tower. Agency methods count rental apartments and hotels as commercial. A tower with real hotel operations can turn into a condotel problem, and condotels are not offered.
- Stacked non-warrantable triggers. Litigation, heavy investor ownership, thin reserves, and deferred maintenance can each sink a building. The agency guide uses a single-entity cap of 20% of units in projects with 21 or more units. It is useful here only to show what lenders mean by owner concentration.
- Recent financing. A unit you just financed at high leverage may have no CLTV headroom, whatever the building looks like.
- A mixed-use label on the building. The label does not make your unit a mixed-use property.
If the Building Does Not Pass
A failed building review does not end your options. It changes the product. Scotsman Guide reports that tighter agency condo definitions have pushed investors toward DSCR loans for non-warrantable units. Most DSCR programs in the network are built around rent covering the full payment, with 1.00 as the point where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
| Item | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Reviewed on | Your credit and DTI | Rent against the payment |
| Leverage | Up to 70% CLTV | Around 75% LTV on a standard rental |
| Title | Individual or revocable trust | LLC possible, per lender program |
| Structure | Floating, interest-only draw | Fixed-rate spine, long terms |
| Building review | Yes | Yes |
Both paths still review the building. A DSCR loan also needs coverage, and clearing 1.00 is not the same as positive cash flow. DSCR compares rent to the payment only. Repairs, vacancy, management, utilities, and capital costs sit outside the number.
Cash-out refinances usually expect about six months of seasoning.
Choosing the Right Program for Your Situation
Work through these in order. Each one eliminates a path.
1. Whose name is on title? An LLC points you to a retitle or a DSCR loan.
2. What is your score? Under 700 rules out an investment line. A 700 and a 720 reach the same ceiling, so do not chase a higher score for this product alone.
3. How much equity is above your liens? Compare your existing liens against 70% of value. If headroom is thin, the line may be too small to matter.
4. Can you carry a floating payment? A line that never converts to fixed carries payment risk. The CFPB booklet warns that falling behind could cost you your home, and the same lien risk applies to a rental unit.
5. Does the building pass? Ask the association for the questionnaire, budget, insurance, and litigation status before you apply.
Tax treatment varies; consult a qualified professional.
The strongest files clear two tests at once: enough equity and enough credit strength. More cash down never erases leverage caps, credit floors, or property eligibility, which still apply in full. To see how these programs fit into the broader picture, read the complete DSCR loans guide.
A pre-application checklist
- Your current mortgage statement, to confirm the lien balance
- The association’s condo questionnaire, budget, and insurance certificate
- The building’s commercial uses, and who owns them
- Any litigation or special assessments the association has disclosed
- Proof of title vesting
Key Terms Defined
CLTV (combined loan-to-value): Every loan against the property, plus the full credit limit of the new line, divided by the property’s value.
Non-warrantable condo: A unit in a project that fails the agency-style tests for conventional loans, often due to commercial space, litigation, or investor concentration.
Project review: The lender’s check of the building itself, separate from your personal credit review.
Draw period: The window when you can borrow from the line. Investment lines here run five years interest-only.
Lien position: Your loan’s place in line for repayment, set by recording order on title.
Vesting: The way title is held, such as in your own name or in a revocable living trust.
Frequently Asked Questions
Can I get an investment HELOC on a condo above a retail floor?
Often yes, if the collateral is your residential unit and the building passes review. Commercial and mixed-use property is not offered as collateral, but a residential unit inside a mixed-use building can qualify as a condo. Lenders review the commercial share case by case, and your 700 credit score and clear title still matter.
Is there a maximum commercial-space percentage?
There is no network-wide figure to quote. Agency guidelines use 35% as a benchmark for conventional loans, but that rule does not bind these lines. Each lender reviews the building on its own terms, and the way space is counted can change the result. Your association can usually tell you what the building contains.
Does rental income help me qualify for a HELOC?
No. The line is underwritten on personal credit and DTI, not on the unit’s rent. If you want rent to carry the file, a DSCR cash-out refinance is the product built around that test.
Can my LLC hold title on the unit and still get the line?
No. Title must be held by an individual or a revocable living trust. If the unit sits in an LLC, you would need a vesting change or a DSCR cash-out refinance instead.
Will I need a full appraisal?
Usually not. Investment lines cap at $500,000, and lines at or below that amount ordinarily run on an automated valuation. A higher CLTV may require a secondary valuation, and you can request a full appraisal in any case. That is worth doing if comparable sales in the tower are scarce.
