The Quick Read: The line is sized by equity, not by how seasonal your business or your rental is. On a second lien behind the first mortgage you keep, the combined loan-to-value (CLTV) tops out at 70% at a 720 score or better, with lines from $50,000 to $500,000, subject to underwriting. The rent decides whether the file qualifies. The equity decides how big the line gets.
- Second lien: up to 70% CLTV (first mortgage plus the new line, divided by value) at 720 or better, lines to $500,000.
- First lien on a rental with no mortgage: up to 75% LTV at 740 or better, 70% LTV from 700 to 739, on lines to $500,000. Larger lines run to $1,000,000 at 65% LTV.
- Rent test: a minimum 1.10x DSCR, measured against the full credit limit.
- Your own business income: not calculated on this line. The owner’s income is never part of the test.
- Availability: 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
What Sets the Size of the Line?
Equity sets the size. The formula is straightforward: take the CLTV cap times the property value, subtract everything already owed against the property, and the remainder is the most the line can be, up to the program’s dollar cap.
Picture a rental valued at $600,000 with a $300,000 first mortgage. At 70% CLTV the combined ceiling is $420,000. Subtract the first mortgage and the room is $120,000. That is illustrative math, and the lender’s own calculation governs.
Three things shrink the number from there:
- A recent purchase or refinance at high leverage often leaves no room under the 70% cap.
- A declining-market flag lowers the ceiling by 5 points, so 70% is the most the program allows, not a guaranteed figure.
- The line cannot go above $500,000 on a second lien, whatever the equity looks like.
A higher credit score does not lift the second-lien ceiling. Strong rent does not buy a bigger line either. It only clears the coverage test.
Does a Seasonal Business Change the Answer?
Not directly. On this line the rent qualifies the file, and the owner’s income is never calculated. There are no W-2s or pay stubs, no traditional personal-income documentation, and no personal debt-to-income ratio. Qualification rests primarily on the rental’s income covering the payment, subject to lender guidelines.
So a landscaper, a ski-shop owner or a marina operator with lumpy personal income is not penalized for lumpy months. The business’s slow winter does not appear in the coverage test.
What still matters is the credit report. The minimum score is 720 for a second lien and 700 for a first lien. The file also needs no 30-day mortgage late in the last 12 months, and at least 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. Those are the personal-file items, and income is not among them.
Where Seasonality Does Matter: The Rental Itself
Seasoning: 6 months since the last note date on the rental, and 6 months of ownership (settlement date to note date).
If the rental is the seasonal asset, say a lake cabin or a beach duplex, seasonality shows up in the rent figure. Rent is the lesser of the appraisal’s Form 1007 market rent and the lease, unless three months of receipts support a lease above market. A lease in place is required.
That second point trips up short-term rental owners. The program is built around a lease and a market rent schedule. An owner who runs a property on nightly bookings should expect the file to be reviewed against those two documents, so confirm with the lender how platform income is treated before building a plan around it. 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.
On a two-to-four-unit property, at most one unit may be vacant. A seasonal owner who leaves two units empty in the off-season has a file problem before the coverage test even starts.
How the Coverage Test Works
The minimum is 1.10x. Gross monthly rent is divided by a qualifying payment, which is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is a stress payment. Taxes and insurance are not part of it.
Two details matter for line sizing.
First, the test runs on the full limit, not on what you draw. A $400,000 line is tested as if all $400,000 were outstanding on a repayment schedule, even though the draw period is interest-only on the drawn balance. A bigger line needs more rent behind it.
Second, on a second lien, confirm on the file how the lender treats the first-mortgage payment in the coverage calculation. The lender’s coverage calculation governs.
So the practical sizing rule is two-sided. Equity caps the line from above. Rent coverage on the full limit caps it from the other direction. The smaller of the two wins. A rental with big equity and thin rent may qualify for less than the equity math suggests.
Seasonal Cash Flow: Draws, Draw Period and Repayment
The structure is friendly to uneven income, with one catch. The draw period is 5 years, interest-only on the drawn balance. After that comes a 25-year fully amortizing repayment period, which brings the line to a 30-year maturity. The rate is variable.
The catch is the draw rules. 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. So this is not a standby line you leave mostly untouched. Plan the closing draw as real borrowing.
The CFPB explains that a HELOC is an open-end line you can borrow against repeatedly, and that payments typically rise once the draw period ends. Experian describes the same draw-then-repayment structure from the consumer side. For a seasonal owner, the date the draw period ends deserves a calendar entry. Peak-season income should be able to carry the amortizing payment before that date, not after it.
Run the stress test in reverse. Take your weakest month of the year and ask whether the owner’s other cash flow covers the interest-only payment on the drawn balance. If it does not, the line is too large for the borrower, even if it is within the program’s limits.
Seasoning and Other Rules That Trim or Block the Line
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).
| Item | Program rule |
|---|---|
| Valuation, lines to $400,000 | Automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal |
| Valuation, lines above $400,000 | Full interior appraisal (Form 1004, 1073 or 1025) |
| Reserves | None required; no cash to close |
| Exposure | At most 5 loans or $2,500,000 per borrower |
| Ineligible property | Rural-designated, condotels, row homes, leaseholds, land trusts, age-restricted, mixed-use, solar lien |
Appraisal waivers are not accepted. All figures are ceilings and floors through select programs, subject to underwriting.
Condotels are the one that surprises seasonal owners. A vacation-area unit in a hotel-style condo building is outside this lane. Row homes and rural-designated property are excluded too, and a property listed for sale in the prior 2 months does not qualify.
First Lien or Second Lien: Which Number Applies?
It depends on whether the rental carries a mortgage. A borrower who keeps a first mortgage can only take a second lien, which carries the 720 floor and the 70% CLTV ceiling. A first lien exists only on a rental with no mortgage, and that includes the larger lines up to $1,000,000, which carry a 65% LTV ceiling at 720 or better.
| Structure | Credit | Leverage ceiling | Line size |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien | 740 or better | 75% LTV | To $500,000 |
| First lien | 700 to 739 | 70% LTV | To $500,000 |
| First lien, larger line | 720 or better | 65% LTV | Above $500,000, to $1,000,000 |
A borrower with a 700 to 719 score and an existing first mortgage is stuck on the second-lien side, because the second-lien floor is 720. That is a credit issue, not a lien-availability issue.
The line also leaves the first mortgage alone. For owners who hold a low-balance first mortgage they like, that is the main reason to pick a second-lien HELOC over a cash-out refinance. A DSCR cash-out refinance on a standard rental can reach about 75% LTV through select programs, so the refinance may produce a bigger check, but it replaces the first mortgage. Lendmire’s complete DSCR loans guide walks through both paths. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Common Mistakes on Seasonal-Owner Files
Most problems on these files come down to the items below.
- Assuming off-season income is tested. On this line, personal and business income are not calculated at all.
- Ignoring the draw rule. At least 80% of the line is drawn at closing. Borrowers who want a mostly unused safety line are looking at the wrong product.
- Forgetting the end of the draw period. Payments move from interest-only to fully amortizing.
- Leaving two units empty. A two-to-four-unit property may have at most 1 vacant unit.
- Using a lease that exceeds market rent without receipts. Three months of receipts are needed to support it.
- Holding the property in the wrong vesting. Vesting in the owner’s LLC is allowed on investment property, with members signing as guarantors, subject to lender program eligibility.
Key Terms Defined
CLTV: the first mortgage balance plus the new line, divided by the property’s value.
DSCR: gross monthly rent divided by the qualifying payment; this program’s minimum is 1.10x.
Stress payment: a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points.
Draw period: the first 5 years, when payments are interest-only on the drawn balance.
Form 1007: the appraiser’s single-family market rent schedule; the 1025 is the companion form for two-to-four-unit properties.
Should You Borrow the Maximum?
Not automatically. The maximum is a ceiling, and with at least 80% drawn at closing, a larger line means a larger drawn balance from day one. For a seasonal owner, the better question is how much interest-only payment the slowest stretch of the year can carry, and how much amortizing payment the peak season can carry after year five. Size the line to the answer, then check that it fits under the equity and coverage caps.
Where the numbers work, the line gives a seasonal owner dry powder without touching a first mortgage and without opening the personal income file. Where they do not, a smaller line or a different structure is the honest answer. Qualification is subject to lender guidelines, credit approval and property review. This is not a commitment to lend.

Frequently Asked Questions
Does my seasonal business income reduce how much I can borrow?
No. The line is reviewed on the rental’s rent, and the owner’s income is never calculated. Your credit report and the rental’s equity still matter, and both are subject to underwriting.
How much equity do I need to have available?
Enough to fit under the cap. On a second lien the first mortgage plus the new line cannot exceed 70% CLTV, so a property already financed near that level leaves little or no room. Lines start at $50,000, so the room has to clear that floor too.
Is the line available on a rental with no mortgage?
Yes, as a standalone first lien. It reaches 75% LTV at 740 or better and 70% LTV from 700 to 739 on lines to $500,000, and larger lines to $1,000,000 carry a 65% LTV ceiling. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
What happens when the draw period ends?
The 5-year interest-only period gives way to a 25-year fully amortizing repayment period, and payments typically rise. Seasonal owners should check that peak-season cash flow can carry that payment well before the switch.
Can I get this line on a rental I just bought?
Not right away. A recent purchase or refinance has to age first, and the owner’s time on title has to build as well. The rule is laid out in the seasoning section above, and the lender confirms both dates from the settlement statement and the note.
Is the DSCR HELOC offered everywhere?
No. It is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. State availability varies, and eligibility is subject to lender guidelines.
