The Quick Read: It depends on the building first and the equity second: once the building passes review, the same leverage tiers apply as for any other property type, and a second-lien line on a rental unit can reach up to 70% combined loan-to-value at a 720 score or better, minus the first mortgage, up to $500,000, subject to underwriting. The commercial floor decides whether the unit is eligible. It does not change the sizing formula.
- Sizing formula: value × combined-leverage ceiling − the first mortgage balance = the most the new line can be.
- Second lien: up to 70% combined loan-to-value (CLTV) at 720 or better, lines from $50,000 to $500,000, on a non-owner-occupied rental.
- First lien (no mortgage on the unit): up to 75% loan-to-value (LTV) at 740 or better, with lines up to $1,000,000 at lower tiers, as laid out in the table below.
- Coverage test: rent must cover a stress payment on the entire line at a minimum of 1.10x, subject to lender guidelines.
- The gate: a residential unit in a mixed-use tower is a building question. A mixed-use or commercial property as the collateral itself is not eligible.
A DSCR HELOC is a revolving line secured by a rental the owner keeps. The rent qualifies it, not the owner’s personal income. This piece covers how the line is sized, how the commercial floor changes the file, and what to check before anyone orders a valuation. Lendmire is a broker. It arranges this product through a wholesale lender in its network, and all terms below are subject to underwriting.
What Is a DSCR HELOC on a Rental Condo?
A DSCR HELOC is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The line is never closed with a purchase, and it is never a third lien.
The LLC can stay on title, depending on program guidelines. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line do not have to match the borrowers on the first mortgage.
The structure fits an investor who wants rental equity without refinancing the first mortgage and without opening the personal income file. Lines on a primary residence or second home are a different, owner-occupied product. This one is for rentals only.
How Does the Commercial Floor Change the Math?
It does not change the math. It changes whether you get to run it. The sizing formula is the same whether the tower has a lobby café or a full retail podium. What differs is the project review, which sits ahead of the borrowing math.
Here is the split that matters on these files:
- You own a residential unit. The commercial floor belongs to someone else. This is a project question. The lender looks at the building, not just your unit.
- You own the commercial space, or your unit is designated commercial. The collateral is commercial or mixed-use property, and it falls outside this program.
- The building is a condotel or hotel-style operation. That is a separate exclusion from a commercial floor, and it also falls outside the program.
Non-warrantable condos are eligible property types on this lane, so a building that fails agency-style tests is not automatically dead. Scotsman Guide’s reporting on DSCR financing notes that DSCR loans cover both warrantable and non-warrantable condos, which is a main reason investors move to them. That does not mean every tower clears. The commercial share, the building’s finances and its operations are still reviewed on the file.
Across the wholesale network, lenders set their own project standards, and they do not all land in the same place. There is no single published commercial-space cap that governs these lines. Treat any number you find online as that source’s rule, not as this program’s rule.
The Sizing Formula, Step by Step
The line is the lesser of what leverage allows and what the program caps. The steps run in this order.
1. Set the value. An automated valuation or an appraisal sets it, depending on line size. Value drives everything after it.
2. Apply the ceiling. On a second lien, multiply value by the 70% CLTV ceiling. That gives the total debt the property can carry.
3. Subtract the first mortgage. What is left is the room for the new line. CLTV counts the first mortgage balance plus the new line, divided by value.
4. Check the line limits. A second-lien line runs from $50,000 to $500,000. If the room is smaller than the minimum, there is no line.
5. Run the rent test. Rent has to cover the stress payment on the entire credit limit at 1.10x or better. A larger line pushes that payment up, so rent can cap the line before leverage does.
A percentages-only example shows the logic. Say value is 100%, the first mortgage is 45% of value, and the ceiling is 70%. Room is 25% of value. A lower first-mortgage balance leaves more room, and a high-balance first mortgage can leave none.
Most of the sizing question is answered by two numbers: the value and the first mortgage balance.
Leverage by Lien Position
| Lien position | Credit score | Maximum leverage | Line range |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien (no mortgage) | 740 or better | 75% LTV | Up to $500,000 |
| First lien (no mortgage) | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien, larger line | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
These are ceilings, not offers, and they apply to non-owner-occupied rental collateral. Below 720 there is no second-lien option. A 700 to 719 borrower who keeps a first mortgage cannot take this line. The first-lien tiers apply only when the rental has no mortgage. A declining-market flag on the property can lower the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower. A higher score does not buy extra leverage inside a tier. It decides which tier you are in.
Does the Rent Test Still Work With a Commercial Floor?
Yes. The test looks at your unit’s rent, not the building’s. The commercial floor does not enter the ratio. The minimum is 1.10x, and it is built on a stress payment.
The stress payment is a fully amortizing payment on the entire credit limit, set above the line’s start rate. It does not include taxes or insurance. It is calculated on the full line, not on the drawn balance, so a large line on a modest rent can fail even when leverage is fine.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The appraiser’s market rent comes from Form 1007. A lease in place is required.
On a second lien, the lender’s coverage calculation governs. Confirm on the file how the lender treats the first-mortgage payment, because that treatment changes the ratio. Property-level cash flow is the heart of DSCR financing. Scotsman Guide’s explainer on DSCR loans describes the focus on whether the property can cover its own costs, including HOA fees. HOA dues are a building-level cost worth pricing into any rental decision, even though they are not part of this program’s qualifying payment.
Who Decides If the Building Passes?
The lender decides, on the file, through project review. A questionnaire to the HOA or management company is the usual starting point. It asks about the commercial share, how many units are investor-owned, pending litigation, reserves, master insurance and delinquent dues.
For contrast, agency loans use a bright-line test. The Fannie Mae Selling Guide limits commercial or mixed-use space in a project to 35%. It counts space above and below grade and measures by square footage. That is an agency rule for agency loans. It is not the rule for a DSCR HELOC, but it is the best-known reference point, and it shows why the method of counting matters.
Counting changes the answer. A building whose commercial space is a modest slice of square footage can look very different if a lender looks at the income the space produces. Parking, hotel-style units and association-run businesses can also move the picture. Ask the management office which measure the questionnaire uses before assuming the building passes or fails.
What the File Needs
The valuation path depends on line size. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, plus a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal. For a condo the appraisal form is the 1073. Appraisal waivers are not accepted.
Title work follows line size too. A first lien and any second lien above $400,000 take a full title policy. Smaller second liens use an owner-and-encumbrance report. Hazard insurance has to cover both liens, and flood coverage is added where required.
Other points that shape the file:
- 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).
- Credit history: No 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- Reserves and cash to close: Neither is required, subject to underwriting.
- Exposure: At most 5 loans or $2,500,000 per borrower with the program.
- Vacancy: A two-to-four-unit property may have at most 1 vacant unit. A high-rise unit is a single unit, but the lease must be in place.
- Borrowers: US citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Documents for a commercial-floor tower run heavier than a standard condo file. Collect the HOA questionnaire, master insurance certificate, budget, the lease, a first-mortgage statement and, if the lender asks, a square-footage breakdown of commercial versus residential space.
How Does the Line Work After Closing?
The line has a 5-year interest-only draw period on the drawn balance. A 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable. The CFPB’s overview of home equity lines describes a HELOC as open-end credit you can borrow against repeatedly, with the draw period in which you spend up to the limit.
At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, that means the whole line is drawn at closing. Later draws are at least $5,000 each. This is not a line to open and leave idle. It suits an investor with a plan for the money, such as rehab on another property, a down payment or reserves.
When the Line Is a Poor Fit
A fixed-structure cash-out refinance gives a lump sum in one closed-end loan. It replaces the first mortgage, which matters if the existing first mortgage carries terms you want to keep. The cash-out path faces its own project review on the same building.
If the line is declined, check which gate failed:
| Failed gate | Likely cause | What to look at next |
|---|---|---|
| Building | Commercial share, hotel-style operation, litigation | A different building, or a different program’s project standards |
| Equity | First mortgage too high for the ceiling | Wait for paydown or appreciation |
| Coverage | Rent too low against the full line | A smaller line, once the lender confirms the sizing |
| Eligibility | Seasoning, score under 720 on a second lien, ineligible property type | Time, credit repair, or a first lien on a paid-off rental |

Pre-Application Checklist for the Building
Run these before anyone orders a valuation.
1. Confirm your unit is residential. Check the deed and the condo declaration for any commercial or mixed-use designation on your unit.
2. Request the HOA questionnaire. Ask what share of the building is commercial and how it is measured.
3. Pull the master insurance certificate and budget. Both are part of project review.
4. Confirm the building is not a condotel. Hotel-style rental programs are excluded.
5. Get the first-mortgage payoff or balance. It sets the room under the ceiling.
6. Check the lease. A lease must be in place, and the rent must support the coverage test.
7. Confirm the state. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Key Terms Defined
DSCR: the debt service coverage ratio, which is gross monthly rent divided by the qualifying payment.
CLTV: combined loan-to-value, the first mortgage balance plus the new line, divided by the property’s value.
Standalone second lien: a line recorded behind your existing first mortgage, which stays in place.
Non-warrantable condo: a condo project that falls outside agency eligibility rules, often because of commercial space, investor concentration or litigation.
Commercial floor: retail, office or other non-residential space in the same building as the residential units.
Draw period: the 5-year interest-only window in which the line can be drawn, before the 25-year repayment period begins.
Frequently Asked Questions
Does a commercial floor make a condo ineligible for a DSCR HELOC?
Not automatically. A residential unit in a building with a commercial floor is treated as a project question, and the share, the counting method and the building’s operations are reviewed. Owning the commercial space yourself, or a mixed-use or commercial designation on your unit, takes the collateral outside the program.
What is the most I can borrow on a rental condo?
On a rental with no mortgage, a first lien can reach 75% LTV at 740 or better, and lines run to $1,000,000 at lower tiers. All of it is subject to underwriting and the rent test. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Can my LLC hold title to the unit?
Yes, on this program, depending on lender guidelines. Vesting in an LLC is allowed for investment property only.
Do I need to refinance my first mortgage to get the line?
No. The line is written as a standalone second lien behind the first mortgage you keep. That is the point of the structure for investors who like their current first mortgage. A paid-off rental can take the line as a first lien instead.
Does a 700 credit score work?
A 700 score works only for a first lien on a rental with no mortgage, where 700 to 739 reaches 70% LTV. A second lien needs 720 or better.
