The Quick Read: It depends on two limits, and the lower one decides. Equity sets the first limit: on a second lien, the program allows up to 70% combined loan-to-value, which means the first mortgage balance plus the new line, divided by value. Rent sets the second limit, because the property must cover a stress payment on the entire line at a coverage ratio of at least 1.10x.
- Second lien: up to 70% CLTV at a 720 credit score or better, lines from $50,000 to $500,000.
- First lien on a rental with no mortgage: up to 75% LTV at 740 or better, 70% at 700 to 739, and 65% on lines above $500,000 (lines run to $1,000,000).
- The rent qualifies the line, not the owner’s personal income, and an LLC can stay on title.
- All figures are ceilings that apply through select programs, subject to underwriting. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
The Formula Behind Every Limit
Your maximum line equals property value times the allowed leverage, minus every lien already recorded on the property. That is the whole equity calculation, and it matches how the CFPB’s HELOC booklet describes setting a credit limit: a percentage of appraised value, less the mortgage balance.
Here is how it plays out under a second lien. Say a rental is worth $500,000 and the first mortgage balance is well under half of that. At a 70% CLTV ceiling, the combined debt can reach $350,000, so the line fits in the gap between the first mortgage and that ceiling. A larger first mortgage shrinks the gap. A rental bought recently at high leverage may have no room at all until the balance falls or the value rises.
Then the dollar caps apply on top. A second-lien line runs from $50,000 to $500,000. A first-lien line can run to $1,000,000, but only at lower leverage once it passes $500,000.
Which Limit Binds: Equity or Rent?
The rent test often binds before equity does. The coverage ratio is gross monthly rent divided by the qualifying payment, and that payment is a fully amortizing payment on the entire credit limit at a stress rate. It is not tested on the drawn balance. A line that would pass if you drew half of it can still fail when tested at full size.
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 must be in place. On a two-to-four-unit property, at most one unit may sit vacant. Taxes and insurance are not part of the qualifying payment. How the first-mortgage payment enters the calculation on a second lien is something to confirm on the file, since the lender’s own coverage calculation governs.
Run it as a decision flow:
1. Compute the equity room: value times the leverage cap, minus liens.
2. Compute the rent room: the largest line whose stress payment keeps rent at 1.10x or better.
3. Your limit is the smaller of the two, then capped at the program’s dollar ceiling.
Picture a landlord with a paid-off duplex worth a lot and a modest lease. Equity room looks enormous. Rent room may be the real ceiling. Now flip it: a single-family rental with strong rent but a big first mortgage. Equity binds first. Knowing which one binds tells you whether to look for more rent or more paydown.
Second Lien or First Lien?
A second lien suits the owner who wants to keep an existing first mortgage in place. A first lien exists only on a rental with no mortgage. The two carry different leverage.
| Factor | Second lien | First lien |
|---|---|---|
| Property | Rental with a mortgage | Rental with no mortgage |
| Max leverage | 70% CLTV | 75% LTV at 740+ |
| Credit floor | 720 | 700 |
| Line range | $50,000–$500,000 | Up to $1,000,000 |
| Above $500,000 | Not available | 65% LTV at 720+ |
A borrower who keeps a first mortgage can only take a second lien, and that needs a 720 score. A 700-to-719 borrower in that position is held back by the credit floor, not by lien type. On a free-and-clear rental, a score of 700 to 739 caps leverage at 70% LTV, while 740 or better reaches 75%. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Credit tiers here buy eligibility and a leverage tier, so check where your score lands before sizing anything. The mortgage history rule is no 30-day late in the last 12 months, and 48 months must pass since a bankruptcy, foreclosure, short sale or deed-in-lieu.
How the Draw Rules Shape What You Actually Get
The word revolving suggests flexibility. This product is tighter than that. 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 must be at least $5,000 each.
So size the line to a real use of funds, not a cushion. Interest-only payments apply to the drawn balance for a 5-year draw period. A 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable. The CFPB’s HELOC explainer describes the general draw-then-repay structure and notes that some plans require an initial or minimum draw, which is the pattern here. The rate and pricing terms come with the lender’s HELOC disclosures.
The File: Valuation, Seasoning, Property Limits
Lines up to $400,000 use an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted.
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).
No reserves and no cash to close are required. Exposure per borrower tops out at 5 loans or $2,500,000 with the program, which matters for anyone scaling a portfolio.
Eligible properties include single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums, plus lots up to 10 acres. These fall outside the program: rural-designated property, row homes, condotels, leaseholds, land trusts, commercial or agricultural property, mixed-use, and a property listed for sale in the prior 2 months. A declining-market flag lowers the ceiling 5 points, and Philadelphia lines carry a ceiling 10 points lower.
Borrowers must be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. The line is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, through a wholesale lender in its network.
DSCR HELOC, Bank HELOC, or Cash-Out Refinance?
Pick by what you need to keep and how much you need.
| Factor | DSCR HELOC | Bank investment HELOC | Cash-out refinance |
|---|---|---|---|
| Reviewed on | Property rent | Personal income and DTI | Rent, through DSCR programs |
| First mortgage | Stays in place | Stays in place | Replaced |
| Typical size | Capped lines | Often smaller | Often more equity |
| Draw style | Mostly funded at closing | Varies by lender | Lump sum |
NerdWallet’s investment-property HELOC explainer says these lines come from fewer lenders and often allow less borrowing than lines on a primary home, and that lenders may require extra appraisals. Its figures describe the bank lane, which underwrites personal income, so don’t blend them with the rent-based program above.
The flip point is simple. If your existing first mortgage is a good one and you need a moderate sum, a second lien keeps it intact. If you need a large amount, a cash-out refinance often reaches more total equity, though it replaces the first loan. Both add debt against the same rent, so both lower coverage.
What to Ask For to Get Better Terms
Better terms here means fitting the product to the deal, not finding a loophole. Ask these before you commit:
- Does the lender’s coverage calculation include the first-mortgage payment on a second lien?
- How is rent used for lender review set on my file: lease, market rent, or receipts?
- What is the full draw schedule, including the closing draw requirement?
- What do the HELOC disclosures say about the rate and pricing terms?
- Does the line allow my LLC to remain on title, subject to lender program eligibility?
Passing the coverage ratio does not mean the property turns a real profit. Check cash flow on your own numbers before pulling equity, and remember that a line secured by a rental puts that rental at risk if repayment fails.
Key Terms Defined
CLTV: Combined loan-to-value, meaning the first mortgage plus the new line, divided by property value.
DSCR: Debt service coverage ratio, meaning gross monthly rent divided by the qualifying payment.
Draw period: The 5-year stretch when you can borrow from the line and pay interest only on the drawn balance.
Seasoning: The time a property must be owned or past its last purchase or refinance before the line is available.
Stress payment: The qualifying payment sized on the full credit limit at a higher test rate than the start rate.
Frequently Asked Questions
What is the most I can borrow on a rental?
A second lien tops out at $500,000 and up to 70% CLTV at a 720 score or better. A first lien on a rental with no mortgage can reach $1,000,000, though leverage drops to 65% LTV above $500,000. Your own limit is the lower of the equity room and the rent room, subject to underwriting, unless three months of rent receipts support a lease above market.
Does my personal income matter?
The rental’s income qualifies the line, and the owner’s income is never calculated, subject to lender guidelines. The lender still reviews credit, title, valuation and equity. Those parts of the file are documented.
How does seasoning work?
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 I draw only what I need?
Not at closing. After that, each draw must be at least $5,000, so plan the line size around a real use of funds.
Can I hold the property in an LLC?
Yes, vesting in the owner’s LLC is allowed for investment property, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
