The Quick Read: Rent decides whether you qualify, but equity decides how much you can borrow. The rent test is a pass-or-fail gate and never enlarges the line. Through select programs, subject to underwriting, the size comes from the property’s value, the combined-leverage ceiling, and every lien already on the rental.
- Second lien: up to 70% CLTV (combined loan-to-value) at a 720 score or better, on lines of $50,000 to $500,000.
- First lien on a paid-off rental: up to 75% LTV at 740 or better, and 70% LTV from 700 to 739, on lines to $500,000.
- Larger first-lien lines run to $1,000,000, at 65% LTV and 720 or better.
- Minimum coverage is 1.10x, tested on a stress payment sized on the whole line, drawn or not.
- No traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines.
A DSCR HELOC is a revolving line of credit secured by a rental you keep. This article walks through the sizing math, the two limits that cap your line, and the situations where thin rent or thin equity shrinks the answer.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a home equity line on a non-owner-occupied one-to-four-unit rental. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR means debt service coverage ratio: gross monthly rent divided by the qualifying payment.
It comes in two shapes. If you keep a mortgage on the rental, the line is a standalone second lien behind it. If the rental has no mortgage, the line is a standalone first lien. It is never closed together with a purchase, never a third lien, and never a line on your own home.
An LLC can stay on title, subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. Lendmire’s complete DSCR loans guide covers the wider family of these programs.
How Do You Size the Line?
You take the lower of two limits. The equity limit comes first: value times the leverage ceiling, minus every lien already on the property. The rent limit comes second: the line must pass the 1.10x coverage test at the full credit limit.
This is how any home equity line is sized. A HELOC borrows against equity, which is value minus what you owe, per the federal consumer-finance regulator’s explanation of HELOCs. The agency’s HELOC booklet describes lenders setting a limit by taking a percentage of appraised value and subtracting what is owed.
Here is the method in four steps:
1. Find the equity ceiling. Multiply the lender’s valuation by the leverage cap for your lien and credit tier.
2. Subtract existing liens. On a second lien, the first mortgage balance plus the new line, divided by value, cannot exceed the cap.
3. Run the rent test on the full limit. Gross rent divided by the stress payment on the entire line must reach 1.10x.
4. Take the lower figure. Whichever limit is tighter is your line.
Picture a rental with a first mortgage equal to 40% of its value. At a 70% CLTV ceiling, the line can use up to 30% of value, if rent also clears the test. Run it on a rental already near the cap and the room disappears.
Which Limit Binds: Equity or Rent?
Rent binds when the property has strong equity but thin income. The rent test works as a gate at the line size you request, so a bigger line lowers coverage even if you never draw a dollar of it.
Why test the whole line? The qualifying payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. That is a stress payment. The program never quotes you that rate here, and the lender’s own calculation governs.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The qualifying payment is principal and interest on the full line. Taxes and insurance are not part of it. On a second lien, confirm on the file how the lender treats the first-mortgage payment.
Consider three rentals, with illustrative coverage only:
| Rental | Rent vs. stress payment | Result |
|---|---|---|
| Strong | Coverage near 1.3x on the full line | Equity sets the size |
| Thin | Coverage near 1.10x | Passes, but little cushion |
| Failing | Coverage below 1.10x | Smaller line needed, or a different product |
In the failing case, the fix is usually a smaller requested line. Lowering the limit lowers the stress payment, which lifts the ratio. A cash-out refinance tests a different loan, so it may suit that rental better.
What Are the Leverage Tiers?
The tiers depend on lien position and credit score. Through select programs, subject to underwriting, second liens top out at 70% CLTV. First liens on paid-off rentals reach 75% LTV. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
| Lien | Credit score | Max leverage | Line size |
|---|---|---|---|
| Second lien (first mortgage stays) | 720+ | 70% CLTV | $50,000–$500,000 |
| First lien (no mortgage) | 740+ | 75% LTV | Up to $500,000 |
| First lien (no mortgage) | 700–739 | 70% LTV | Up to $500,000 |
| First lien, larger line | 720+ | 65% LTV | Over $500,000 to $1,000,000 |
Below 720 there is no second-lien tier. A borrower with a first mortgage can only take a second lien, so the 720 score is the gate. The first-lien floor is 700, and a first lien exists only on a rental with no mortgage.
A paid-off rental is not unlimited borrowing. The cap still applies, and larger lines demand lower leverage. A declining-market flag on the property lowers the ceiling by 5 points. These figures are ceilings, never offers.
What Does the File Need?
Mortgage history matters as much as score. The file needs no 30-day mortgage late in the last 12 months. It also needs 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required.
Valuation depends on line size. Lines up to $400,000 can use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted.
A lease must be in place. A two-to-four-unit property may have at most one vacant unit. Borrowers can be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Exposure is capped at five loans or $2,500,000 per borrower with the program. Count your existing lines before you plan a second one.
How Soon After Buying Can You Borrow?
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). That is the whole seasoning rule, and it applies to every file.
Property type also matters. Eligible properties include single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums, plus lots up to 10 acres. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, mixed-use, and properties listed for sale in the prior 2 months fall outside this lane.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Philadelphia lines carry a ceiling 10 points lower.
Does Passing 1.10x Mean the Rental Really Cash Flows?
No. The coverage ratio is a qualifying test, not a budget. It uses gross rent against principal and interest on the full line at a stressed rate. Your real month includes taxes, insurance, vacancy, repairs and management, and none of those sit in the qualifying payment.
The draw terms add another layer. The draw period is 5 years of interest-only payments on the drawn balance. Then a 25-year fully amortizing repayment period begins, with a 30-year maturity. The rate is variable, so payments can move. Plan for the day the payment steps up, because the rent must carry it then.
At least 80% of the line is drawn at closing, and the closing draw is never under $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 you open to leave mostly idle.
Risk runs both ways. The CFPB notes that a lender may reduce or freeze a line if home value drops significantly. Missed payments can also put the secured property at risk. On a rental, the collateral is your investment property.
A sensible approach sizes the line to the rent and the plan, not to maximum equity. The stronger play is often a line smaller than the ceiling, with room in the monthly budget. Lendmire’s piece How to Use an Investment Property HELOC When Rental Cash Flow Dips covers what to do when income softens.
DSCR HELOC, Cash-Out Refinance, or Something Else?
Each product answers a different need. A DSCR HELOC keeps a first mortgage you like and adds a revolving line behind it. A cash-out refinance replaces that mortgage with one new loan. Choose based on whether your need is staged or a defined lump sum.
| Factor | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Structure | Revolving line | One loan |
| Coverage test | Full line, stress payment | The new loan |
| Best for | Staged or uncertain needs | One defined lump sum |
Banks also write HELOCs on rentals, but the lender pool is small. NerdWallet notes that not all lenders offer them and qualification is strict. The DSCR product here differs: rent qualifies the line, with no reserves required, subject to lender guidelines.
Lendmire also places a separate investment property HELOC qualified on your personal income. That one is underwritten on credit, debt-to-income and income, and an LLC cannot hold title. Keep the two apart when comparing.
Common Misreadings
High rent means a bigger line. It does not. Rent passes or fails the test. Value, leverage cap and existing liens set the size.
Only the drawn balance counts. Not here. The stress test covers the whole limit.
A higher score always buys more leverage. Score sets the tier, and each tier has its own ceiling. Beyond the top tier, more score adds nothing.
Skipping personal income means skipping scrutiny. Credit, value, equity and mortgage history are all reviewed. The rent, the lease, the credit report and the valuation are documented.
Frequently Asked Questions
Can an LLC hold a DSCR HELOC?
Yes, subject to program terms. The LLC can stay on title for an investment property. Its 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 match those on the first mortgage.
What if my first mortgage is already close to the cap?
Then little or no line is available. The minimum line is $50,000. If your first mortgage plus a $50,000 line would exceed 70% CLTV, a second lien does not fit. A cash-out refinance, which tests a new loan, may be the better route.
How does a bigger line affect coverage?
A bigger line lowers it. The qualifying payment is sized on the entire credit limit, so a larger limit raises the stress payment and drops the ratio. Requesting a smaller line is the direct way to clear 1.10x.
How soon after buying can I open one?
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 are subject to underwriting.
Can I use a vacant rental?
Not on a single-unit property, since a lease in place is required. On a two-to-four-unit property, at most one unit may sit vacant. The lender’s coverage calculation governs.
