The Quick Read: It depends on how much of the condo’s value your first mortgage already uses: on this program, a rental condo’s first mortgage plus the new line can reach 70% of value at a 720 credit score or better, so your maximum line is 70% of value minus what you still owe, subject to underwriting. Lines run from $50,000 to $500,000. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
- Leverage: 70% combined loan-to-value (CLTV) on a second lien at 720 or better. Below 720 there is no second-lien option.
- Size: lines from $50,000 up to $500,000 behind your existing first.
- Rent test: 1.10x minimum on a stress payment covering the whole line.
- Condo twist: the building gets reviewed too. Warrantable and non-warrantable condos are both eligible property types.
- Room can be zero: if the first mortgage already uses 70% of value, no line fits.
Key Terms Defined
DSCR (debt-service coverage ratio): gross monthly rent divided by the qualifying payment. It shows whether the rental pays for itself.
CLTV (combined loan-to-value): your first mortgage balance plus the full new line, divided by the property’s value. Experian’s explainer describes the same calculation, and Investopedia gives a general definition.
Second lien: a loan that sits behind your first mortgage in repayment priority. You keep the first mortgage untouched.
Draw period: the stretch when you can borrow from the line and pay interest only on what you drew.
Warrantable condo: a condo project that meets standard lender rules on owner mix, finances, and litigation. A non-warrantable project misses one or more of them.
How Do You Calculate the Maximum Line?
Take 70% of the condo’s value. Subtract your first mortgage balance. Subtract any other lien on the property. What is left is the most the line can be, before the rent test and building review. That is how most programs in the wholesale network Lendmire works with size a second lien: the ceiling covers all debt against the property, not just your equity.
Two details trip people up.
First, the full line counts, not the amount you plan to draw. A $150,000 line is measured as $150,000 even if you take less later.
Second, a different second lien or an open line already on the condo eats into the same 70%.
The value comes from the lender’s valuation, not your estimate. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal, which on a condo is the 1073 form. Appraisal waivers are not accepted. If the valuation comes in under your number, the room shrinks with it. A market flagged as declining lowers the ceiling by 5 points.
What Does the Math Look Like at Different First-Mortgage Balances?
Run the numbers on a hypothetical condo, expressed in percentages of value so any price works. Assume a 720 score and the 70% second-lien ceiling.
| First mortgage uses | Room for the line | Read |
|---|---|---|
| 40% of value | 30 points of value | Plenty of room |
| 50% of value | 20 points of value | Workable on most values |
| 60% of value | 10 points of value | Only fits on a higher-value condo |
| 70% of value or more | None | No second-lien line |
The $50,000 minimum is what makes the third row tricky. Ten points of value only reaches $50,000 on a condo worth $500,000 or more. On a modest unit, the same 10 points is a number too small to write. Thin-equity condos often fall out right here, before rent is even tested.
This is arithmetic for illustration. The lender’s own calculation governs, and every file is underwritten individually.
Does the Rent Still Have to Cover It?
Yes. Room under the ceiling is only the first gate. The second is a minimum DSCR of 1.10x. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
The qualifying payment is not what you will actually pay. It is a fully amortizing payment on the entire credit limit, calculated at the start rate plus 2 percentage points. It covers principal and interest only. Think of it as a stress payment, built to be heavier than your real draw-period payment.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease in place is required. In a two-to-four-unit building, at most one unit can sit vacant.
How the first-mortgage payment joins the math on a second lien is not spelled out in the program terms. Confirm on the file how the lender treats it. This is also where condo dues bite. Even where dues sit outside the qualifying payment, they hit your real cash flow, so ask how the lender’s coverage calculation handles them before you count on a larger line.
The rent qualifies the line. The program does not use tax returns, W-2s, pay stubs, or a debt-to-income ratio. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The lender still pulls credit, orders a valuation, and checks your lease. For the wider picture, see Lendmire’s complete DSCR loans guide.
What Shrinks Your Number on a Condo?
Start with credit. At 720 or better you get the 70% ceiling. Below 720 the second-lien door closes. Also expect no 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu.
Then comes the building. Lenders look at the project’s finances and rules: dues collection, reserves, litigation, how many units are investor-owned, and rental restrictions. The rent test and the building review are separate gates. A strong ratio does not rescue a troubled building. Non-warrantable projects are eligible property types here, but they get a closer look.
Seasoning matters too. 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).
Finally, check what the property is. These are outside this lane:
- Condotels
- Row homes
- Rural-designated property
- Leaseholds and land trusts
- Age-restricted communities
- Mixed-use property
- A property listed for sale in the prior 2 months
- A property with a solar lien
Also read your first mortgage note for any clause about additional liens. That is a contract question, not a DSCR one, and it is worth settling before you apply.
What If the Condo Has No First Mortgage?
Then a first-lien line is available instead, with different leverage. On lines up to $500,000, loan-to-value reaches 75% at a 740 score or better and 70% from 700 to 739. Lines above $500,000, up to $1,000,000, carry a 65% ceiling at 720 or better. The first-lien floor is a 700 score.
If you keep a first mortgage, though, it is a second-lien line only, with the 720 floor and the 70% CLTV ceiling. Those figures are ceilings, not offers. Underwriting decides what a file earns.
How Does the Line Work After Closing?
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.
The draw period lasts 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period begins, for a 30-year maturity. The rate is variable.
That payment step-up deserves respect. The CFPB’s HELOC brochure explains that a line moves from a draw period into repayment, and that the bill can jump when the interest-only stretch ends. Plan for the repayment-period payment, not only the draw-period one. Interest-only payments can carry real risk, especially if the balance or the variable rate rises.
Why Keep the First Mortgage Instead of Refinancing?
Because you may not want to disturb it. A second lien leaves your first mortgage exactly as it is. A cash-out refinance replaces it. The right choice depends on your first mortgage terms, your equity, and your goals.
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance | Bank investment HELOC |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Usually stays |
| Reviewed on | Rent coverage | Rent coverage | The bank’s income rules |
| Structure | Revolving line | One lump sum | Revolving line |
| Title in an LLC | Allowed, subject to program terms | Depends on program | Depends on the bank |
The bank column describes how banks typically work. It is not this program’s rules. Banks usually weigh your personal income, so the trade is documentation for leverage and structure.
Can the LLC Stay on Title?
Yes, for investment property only. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line need not be the borrowers on the first mortgage. This is subject to lender program eligibility.
The program is never offered on your own home or a second home. It is never closed together with a purchase, and it is never a third lien. Borrowers must be US citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Where Is the Line Not Worth It?
Three situations come up.
Thin room. If the leftover room barely clears $50,000, the fixed cost of a lien and valuation may not make sense. A different tool may fit better.
Heavy dues, weak rent. A condo that rents modestly against its stress payment can miss 1.10x even with plenty of equity. The line is sized by value but approved by rent.
Big exposure already. The program allows at most 5 loans or $2,500,000 per borrower. Investors with growing portfolios can hit that cap before they hit their equity.
Also ask whether the product really revolves. Some products marketed as home equity lines are closed-end seconds. Those hand you a fixed sum once. A true line lets you draw again after closing, subject to the program’s draw rules.
Pre-Application Checklist
Gather these before asking for a quote:
- Your current first mortgage balance and any other lien on the condo
- Your best estimate of value
- The lease in place and recent rent receipts
- Your title or vesting documents, including LLC papers if applicable
- Dues amounts and the condo association’s contact details
- A date check: when you bought or last refinanced
Sizing the line takes a few minutes with these in hand.
Frequently Asked Questions
What is the maximum CLTV on a DSCR HELOC behind my first mortgage?
Up to 70% at a 720 credit score or better, subject to underwriting. The figure is combined: your first mortgage balance plus the full new line, divided by value. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Does a condo get a lower leverage cap than a house?
Not on this program. The leverage tiers govern every eligible property type, so a condo has no separate cell. What changes is the file. The building review, the dues, and the valuation all affect whether the condo clears, and that can shrink or block the line even when the CLTV math works.
Does the line count the amount I draw or the full limit?
The full limit. CLTV adds your first mortgage balance and the whole new line, even if you plan to draw less later. The stress payment for the rent test also runs on the entire credit limit. Size the line you actually need rather than the largest one the ceiling allows.
Can I get a line if my credit score is 700 to 719?
Not as a second lien behind your first mortgage, because the second-lien floor is 720. A first-lien line exists only on a rental with no mortgage, and that floor is 700. If you keep a first mortgage, a different product such as a cash-out refinance may fit better.
Do I need tax returns or pay stubs?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The lender still reviews your credit report, your lease, and the valuation, and the program carries a 1.10x coverage test.
The Bottom Line
