The Quick Read: Through select programs, a second-lien DSCR HELOC runs from $50,000 to $500,000, subject to underwriting, and irregular deposits do not set where you land in that range. The line is sized on the rental’s rent, the equity left after your first mortgage, and your credit score, not on how steady your personal bank deposits look from month to month, and the lowest of those caps wins.
- The rent qualifies the line. No traditional personal-income documentation, W-2s or personal income calculation apply, subject to lender guidelines.
- Rent must cover a stress payment on the entire credit limit at 1.10x or better, not just on the drawn balance.
- A second-lien line tops out at 70% combined loan-to-value at a 720 score or better.
- At least 80% of the line is drawn at closing, so interest starts on most of it.
- Deposits matter only at the edges: rent receipts, and the source of any unusual funds a lender asks you to document.
What Is a DSCR HELOC, and Why Don’t Your Deposits Drive It?
A DSCR HELOC is a revolving line of credit on a rental you keep. The debt service coverage ratio (DSCR) is the property’s monthly rent divided by the qualifying payment. A line that is reviewed on that ratio looks at the building’s income, not yours.
The line is written one of two ways. It can be a standalone second lien behind the first mortgage you keep. Or it can be a standalone first lien on a rental with no mortgage. It is never closed with a purchase, and it is never a line on your own home. Your LLC can stay on title, with the members signing as guarantors, subject to program terms.
Because the rental qualifies the line, the file does not average your deposits. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A self-employed investor with lumpy personal income does not have to defend a deposit pattern. The trade-off is that credit, equity and the property itself get a hard look.
Where Do Irregular Deposits Matter, and Where Don’t They?
They matter in two narrow places. Everywhere else they are not part of the test.
The first is rent evidence. A lease must be in place. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. Those receipts are deposits, but they prove the property’s income, not yours.
The second is the source of funds. This line asks for no reserves and no cash to close. If a lender still asks you to document a large, unusual recent deposit, that is a question about where the money came from. It is not an income average, and it does not shrink the line.
Compare that with a bank statement HELOC, where deposits are the income. That product typically reviews 12 to 24 months of statements, still checks credit, debt and equity, and wants title in an individual or a revocable trust, not an LLC. Lendmire’s comparison of a bank statement HELOC and a super jumbo cash-out for irregular deposits covers when that route makes sense.
| Path | What it tests | Do your deposits count? |
|---|---|---|
| DSCR HELOC | Rent vs. stress payment | No, only as rent receipts |
| Bank statement HELOC | Deposits as income | Yes, the core test |
| Personal-income investment HELOC | Income and debt ratio | Through income documents |
| DSCR cash-out refinance | Rent vs. new payment | No, closed-end lump sum |

How Much Can You Borrow?
Four Caps, Lowest One Wins
Your maximum line is the smallest result of four tests. Think of it as four doors, and the line can only be as large as the narrowest.
The equity cap
On a second lien, combined loan-to-value (CLTV) is your first mortgage balance plus the new line, divided by the property’s value. The ceiling is 70% at a 720 credit score or better, on lines up to $500,000. Say your first mortgage is 50% of value. That leaves about 20% of value for the line. A first mortgage at 60% of value leaves about 10%. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
On a first lien, a rental with no mortgage, leverage is measured as loan-to-value (LTV). It reaches 75% at a 740 score or better and 70% from 700 to 739, on lines up to $500,000. Lines above $500,000, to a $1,000,000 maximum, carry a 65% LTV ceiling at 720 or better. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Market surveys report that lenders on investment HELOCs generally want at least 20% equity, according to NerdWallet’s investment-property HELOC explainer. The requirement is stricter on a second lien, where the 70% CLTV ceiling implies at least 30% equity remaining after the line is added.
The rent cap
This is the one people miss. The coverage test runs on a fully amortizing payment on the entire credit limit, at the start rate plus 2 percentage points. It is a stress payment, and it covers principal and interest only. Taxes and insurance are not part of it.
Minimum coverage is 1.10x. So a bigger line means a bigger test payment, and coverage falls as the line grows. Run it this way: if rent covers a given line at 1.30x, that line could grow by roughly 18% before coverage reaches 1.10x. Past that point, the rent cap, not the equity, sets your limit.
A property can have plenty of equity and still size smaller than the equity suggests. Whether the first-mortgage payment joins the qualifying payment on a second lien is something to confirm on the file with the lender. The lender’s own calculation governs, and any arithmetic here is illustrative.
The credit tier
On a second lien, 720 is the only tier, so a higher score does not buy more leverage. On a first lien, the score does move the ceiling: 740 gets 75% LTV, and 700 to 739 gets 70%. Mortgage history matters too. The lender looks for no 30-day late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
The program and property cap
Lines start at $50,000. Second liens stop at $500,000, and first liens reach $1,000,000 under the 65% ceiling on the larger lines. A single borrower can hold at most 5 loans or $2,500,000 with the program. A declining-market flag lowers the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
A Worked Sizing Example
Picture a single-family rental with a first mortgage at 55% of value and a borrower at a 725 score. The equity cap leaves about 15% of value for a second-lien line. That is the first door.
Now test the rent. Suppose the lease and the appraiser’s market rent are close, so rent used for lender review is whichever is lower. If that rent covers a stress payment on the full 15%-of-value line at roughly 1.25x, the rent test passes, and the equity cap is the binding one.
Change one input. The first mortgage drops to 40% of value, which opens up about 30% of value of room. The stress payment on that bigger line is roughly double, and coverage falls toward 0.6x to 0.7x. The line now fails the rent test. It would need to shrink until coverage returns to 1.10x. Here the rent cap binds, even though equity is abundant.
These ratios are modeled assumptions, not market data. The lender’s own calculation governs.
How the Draw Rules Change the Math
On the smallest lines, the whole line is drawn at closing. Later draws are at least $5,000 each.
The line is interest-only on the drawn balance for a 5-year draw period. A 25-year fully amortizing repayment period follows, for a 30-year maturity, and the rate is variable. The rate and the pricing terms come with the lender’s disclosures.
This is not a free standby reserve. Interest starts on most of the line on day one, so the line carries a cost from the start. Size it to what you will actually put to work.
Variable and Seasonal Rent: How Lenders Read It
The program requires 6 months since the rental’s last note date and 6 months on title (settlement date to note date).
Lenders do not average your deposits, and they do not accept gross booking revenue as qualifying income. They use a lease and the appraiser’s market rent schedule (Form 1007 on a single-family property), and they take the lesser of the two, unless three months of receipts support a lease above market.
A two-to-four-unit property may have at most 1 vacant unit. A lease in place is required, so a property run on nightly bookings should be checked against that rule first. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. Some HELOC lenders restrict by location or by year-round renting, and the lender pool for investment-property lines is smaller than for a primary-residence line.
Seasoning and Eligibility: The Two Six-Month Clocks
Both six-month seasoning rules are laid out in the Variable and Seasonal Rent section, and they apply to every property you plan to use as collateral.
The line also has to exist before you go under contract on your next property. It cannot be opened against a property you do not yet own. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
Property types in the program include single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums, plus lots up to 10 acres. Rural-designated property, condotels, row homes and leaseholds sit outside it. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
What Is the Business-Purpose Angle?
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. The CFPB’s text of Regulation Z excludes credit extended primarily for a business purpose, and the official interpretations at Cornell Law School say that applies even when a dwelling secures the loan. Keep clear records of how you use the proceeds.
If the Numbers Don’t Fit
When a line comes up short, you have a few moves:
1. Shrink the line. Coverage is tested on the whole limit, so a smaller line raises the ratio.
2. Support the rent. Three months of receipts can support a lease above market rent.
3. Wait on seasoning. Both six-month clocks have to be cleared first.
4. Change the structure. A DSCR cash-out refinance replaces the first mortgage with a single closed-end loan, which can fit when title, leverage or loan size does not suit a line.
5. Switch tests. If your deposits are strong and the rental is weak, a bank statement route tests different things, though it needs individual or revocable-trust title.
Key Terms Defined
DSCR (debt service coverage ratio): the rental’s 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.
Qualifying payment: the stress payment on the entire credit limit that rent must cover, principal and interest only.
Draw period: the first 5 years, when you pay interest only on the drawn balance.
Seasoning: the waiting period since you bought, refinanced or took title to the rental.
Lien: a lender’s claim on the property. A second lien sits behind the first mortgage.
Frequently Asked Questions
Do irregular deposits reduce how much I can borrow on a DSCR HELOC?
No, deposits are not averaged into the limit. The line is sized by rent coverage, equity and credit. A lender may ask about the source of a large unusual deposit if it is part of funds being documented, but that is a sourcing question, not an income test. Everything is subject to underwriting.
What is the most I can borrow?
On a second lien, up to $500,000 at up to 70% CLTV and a 720 score or better. On a first lien, up to $1,000,000, with a 65% LTV ceiling on lines above $500,000.
Can I draw less than the full line at 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, the whole line is drawn. Later draws are at least $5,000 each. Plan for interest on most of the line from the start.
How long do I have to own the rental first?
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).
Can my LLC hold title and still get the line?
Yes, subject to program terms. The LLC can stay on title for an investment property, and the members sign as guarantors. A personally underwritten investment HELOC works differently, and the bank statement route wants individual or revocable-trust title.
