The Quick Read: A clean 0x30 history decides whether you qualify. It does not decide how much you can borrow. On a second lien, the line is the property value times 70% combined loan-to-value (CLTV), minus the first mortgage balance, then limited by the rent test and a $500,000 cap, subject to underwriting.
- 0x30 means no payment 30 or more days late in the last 12 months. It is pass or fail.
- On a second lien, leverage tops out at 70% CLTV at a 720 credit score or better, on lines of $50,000 to $500,000.
- On a first lien (a rental with no mortgage), leverage runs 65% to 75% LTV, with lines up to $1,000,000.
- The rent must cover a stress payment on the entire line at a 1.10x minimum.
- Equity, rent coverage, line minimums and the dollar cap each can set the final number. The tightest one wins. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Many investors assume a spotless record earns a bigger line. It doesn’t. A late payment can take you out of the program, but a perfect record only gets you in the door. Everything after that is math on equity and rent. This guide walks through that math, shows where the answer can be zero, and covers what to do if your history isn’t clean. For the full picture of how DSCR lending works, see Lendmire’s complete DSCR loans guide.
What Does 0x30 in the Last 12 Months Actually Mean?
It means zero mortgage payments were 30 days or more past due during the most recent 12 months. The first number is how many lates. The second is how late. The third is the look-back window. A single payment that slid past 30 days inside that window fails the test.
On this program, the rule is simple: no 30-day late in the last 12 months. A payment that posted a few days after the due date but before the 30-day mark does not trip it. The lender reads the mortgage tradeline on your credit report. Servicer statements can help you check your own record before you apply.
Two edge points matter. First, a late older than 12 months does not fail this test, though a bankruptcy, foreclosure, short sale or deed-in-lieu has its own rule: 48 months must pass. Second, a 60-day late fails exactly as a 30-day late does. The test asks only whether you crossed 30.
Programs differ on which mortgages they review. Some look at the subject property only. Others look at every mortgage you hold, including your own home. Confirm on the file which loans the lender will read, because one late on a home loan could matter even if the rental is spotless.
Is a Clean History a Gate or a Dial?
It is a gate. Meet it and you move into the pool of eligible borrowers. Miss it and the file stops, no matter how much equity the rental holds.
After the gate, your credit score tier and the lien position set leverage. On a second lien, the only tier is 720 or better, at 70% CLTV. On a first lien, a 740 score or better allows 75% LTV, and 700 to 739 allows 70% LTV. Lines above $500,000 on a first lien carry a 65% ceiling at 720 or better. Those are ceilings, not offers, and every file is underwritten individually. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Notice what is missing: any reward for a longer or cleaner streak. A borrower with a flawless five-year record and one with exactly 12 clean months face the same leverage table. The gate is binary. The dial is your credit score.
What Is a DSCR HELOC, and How Is It Different From a Cash-Out Refinance?
A DSCR HELOC is a revolving line of credit on a rental you keep. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It is written as a standalone second lien behind your existing first mortgage, or as a standalone first lien on a rental with no mortgage.
A cash-out refinance does the opposite. It replaces the first mortgage with a bigger one. If your current first mortgage is one you like, a second lien lets you leave it untouched and tap the equity beside it.
The CFPB describes a HELOC as an open-end line of credit that lets you borrow repeatedly against the equity in your property, where equity is value minus what you owe. The FTC adds that you pay interest only on what you have drawn. Both descriptions fit this product, with one difference: the rent, not your paycheck, qualifies the line.
Other details worth knowing:
- The property must be a non-owner-occupied one-to-four-unit rental. This line is never offered on your own home or a second home.
- Your LLC can hold title, subject to program terms. The members sign as guarantors.
- The line is never closed with a purchase and is never a third lien.
- The rate is variable. The rate and pricing terms come with the lender’s disclosures.
Lendmire is a broker. It arranges these lines through a wholesale lender in its network, and the program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
How Is the Maximum Line Calculated?
Start with value, apply the leverage ceiling, subtract what you owe, then check the result against the rent test and the dollar limits. The lowest result is your line.
The steps:
1. Value the property. 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. Appraisal waivers are not accepted.
2. Apply the ceiling. Second lien: 70% CLTV. First lien: 65% to 75% LTV by score and line size.
3. Subtract existing liens. On a second lien, the first mortgage balance comes off the top.
4. Run the rent test. Rent must reach 1.10x on the stress payment for the whole line.
5. Check the floor and cap. Lines start at $50,000 and the second-lien cap is $500,000. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Here is a second-lien walk-through in ratios only. Say a rental is valued at $600,000 with a first mortgage that sits at roughly 40% of value. At 70% CLTV, about 30% of value is available. That is the equity-based line. If the rent comfortably clears 1.10x on that size, the line stands. If it doesn’t, the line shrinks until the coverage works.
A second case. The first mortgage sits near 65% of value. At 70% CLTV, only about 5% of value remains. On a mid-priced rental, that is below the $50,000 minimum, so the answer is no line at all.
The valuation matters more than most investors expect. A lower value cuts the line directly, because the ceiling is a percentage of it. A declining-market flag lowers the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
What Does the Rent Test Do to Your Line Size?
The rent test can cap the line even when equity is plentiful. The program requires gross monthly rent divided by a qualifying payment to reach at least 1.10x. That qualifying payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is a stress payment, built to be harsher than what you’d actually pay.
Two points trip people up. The test runs on the whole line, not just the drawn amount. A $300,000 line is tested as if fully borrowed, even if you draw less later. And the qualifying payment is principal and interest only. Taxes and insurance are not part of it.
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. A two-to-four-unit property can have at most one vacant unit.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. The lender’s own calculation governs, and any arithmetic here is illustrative.
The practical effect: a rental with strong equity but modest rent may qualify for a smaller line than the equity table suggests. Rent, not equity, becomes the binding limit. The appraiser’s market rent figure, taken from Form 1007, often drives this.
Which Limit Binds? A Side-by-Side View
| Limit | What it measures | Typical bite |
|---|---|---|
| Leverage (CLTV/LTV) | Value times ceiling, minus liens | Binds when existing liens are large relative to value |
| Rent test | 1.10x on the full-line stress payment | Binds when rent is thin |
| Line floor | $50,000 minimum | Zeroes out thin-equity files |
| Dollar cap | $500,000 (second lien) | Binds on large, low-debt rentals |
| 0x30 history | No 30-day late in 12 months | Pass or fail only |
Each file lands on whichever line is smallest. Subject to underwriting, that is your borrowing power.
When Is the Answer Zero?
Four situations produce no line. Know them before you spend money on a valuation.
Not enough equity. If your first mortgage already sits near 70% of value, nothing remains under the ceiling. A below-720 score makes it worse, because there is no second-lien tier below 720.
Rent too low. If rent can’t reach 1.10x on a stress payment for even the minimum $50,000 line, the file fails. Raising rents with a new lease helps, but the appraisal’s market rent still caps the figure unless three months of receipts support a higher lease.
The line is below the minimum. When the math produces less than $50,000, there is no product. 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 property or timing is out. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, mixed-use, and a property listed for sale in the prior two months are all outside the program. So is a property with a solar lien.
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).
How Do Draws and Repayment Shape the Real Cost?
The line has a 5-year interest-only draw period on the drawn balance. After that comes a 25-year fully amortizing repayment period, for a 30-year maturity. If you sell the property, you generally must pay off the line in full. Plan your exit before you draw.
Payment shock at the end of the draw period is real. Interest-only payments on a drawn balance turn into fully amortizing payments, which are higher for the same balance. That is why the stress test uses a full-amortization payment.
Exposure limits apply across your portfolio. A borrower can carry at most 5 loans or $2,500,000 with the program. No reserves and no cash to close are required, which sets this line apart from many purchase-money DSCR loans. Documentation still matters: the rent, the lease, the credit report and the valuation are all reviewed.
What If Your History Isn’t Clean?
You have four realistic paths, outlined in the table below. All are subject to lender guidelines.
| Situation | Path | Tradeoff |
|---|---|---|
| One 30-day late inside 12 months | Wait until the window clears | Line is unavailable until then |
| Late on a home loan, not the rental | Confirm which mortgages the lender reads | Rules differ by program |
| Credit event in the lookback period | Wait until the lender’s lookback period has passed | Program stays closed until the lender’s guidelines are met |
| Needs cash now | Compare a DSCR cash-out refinance | Replaces your first mortgage |
Some other non-QM programs allow one 30-day late, usually with lower leverage. This one does not. If the HELOC is closed to you, a cash-out refinance may be open under different history rules. Lendmire’s piece DSCR HELOC vs DSCR Cash-Out Refinance With a 0x30 Mortgage History in the Last 12 Months covers that choice in detail.
Pre-Application Checklist
Do these before you ask for a line:
- Pull your credit report and read every mortgage tradeline, including your own home.
- Compare each mortgage payment date against your servicer’s records for the last 12 months.
- Pay on or before the due date until you apply. Autopay removes the risk of a slip.
- Gather the current lease and three months of rent receipts.
- Avoid a new first mortgage or purchase in the last 6 months if you want this line.
- Estimate value and your first-mortgage balance, then test the equity math above.
- Check that the property type and location are eligible.
Key Terms Defined
0x30x12: Zero payments 30 or more days late in the last 12 months.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property value.
Second lien: A loan that sits behind your first mortgage and is paid second if the property is sold or foreclosed.
Draw period: The stretch when you can borrow from the line; here, 5 years of interest-only payments on the drawn balance.
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment. The program minimum is 1.10x.
Frequently Asked Questions
Does a longer clean mortgage history raise my line?
No. The rule is a single check: no 30-day late in the last 12 months. Leverage depends on credit score tier, lien position and line size, not on how many years of clean payments you have.
Does the 0x30 test cover only the rental’s mortgage?
It depends on the program, and you should confirm it on the file. Some programs read only the subject property’s mortgage. Others read every mortgage you hold, including your primary residence. Pull your full credit report and check each tradeline so nothing surprises you.
How soon after buying or refinancing can I open a line?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date). Both must be satisfied before the file can proceed.
Can my LLC hold the property?
Yes, subject to program terms. Vesting in your LLC is allowed on this investment-property line. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment. Foreign nationals and ITIN borrowers are not eligible.
What is the biggest line available?
On a second lien, $500,000 at 70% CLTV with a 720 score or better. On a first lien, lines run to $1,000,000, but above $500,000 the ceiling is 65% LTV at 720 or better. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
