The Quick Read: On a rental with no mortgage, the maximum line is the property’s value times a leverage ceiling, and nothing is subtracted because no other lien exists. Through select programs, that ceiling is typically 75% loan-to-value at a 740 score or better, on lines up to $500,000, subject to underwriting.
- Lines above $500,000 (up to $1,000,000) typically top out at 65% LTV.
- The rent must cover a stress payment on the whole line, at a 1.10x minimum.
- Lines vary by scenario, and at least 80% is drawn at closing.
- This only works on a rental, never on your own home or a second home.
How the Math Works When There Is No Mortgage
A line of credit is sized from value, not from what you want to spend. The first step is the same on every home equity line. As the CFPB’s HELOC booklet describes it, lenders take a percentage of the appraised value and then subtract the mortgage balance.
Your rental has no mortgage, so the subtraction step is zero. That is the whole difference. The line is written as a standalone first lien, which means plain loan-to-value (LTV) applies instead of combined loan-to-value (CLTV). LTV is the loan divided by the property’s value. CLTV adds the first mortgage balance to the new line before dividing.
Here is the formula in three steps:
1. Take the property’s value from the valuation.
2. Multiply by the ceiling for your credit score and line size.
3. Check the result against the dollar cap and the rent test.
The lowest of those three answers is your line. Through select programs and subject to underwriting, that is how the number gets set.
What Ceiling Applies to a First-Lien Line?
The ceiling steps down with credit score and line size. These are program ceilings and floors, never offers.
| Credit score | Line size | Typical max LTV (first lien) |
|---|---|---|
| 740 or better | Up to $500,000 | 75% |
| 700 to 739 | Up to $500,000 | 70% |
| 720 or better | $500,000 to $1,000,000 | 65% |
The first-lien floor is a 700 score. Below that, a first-lien line is not available through this program.
A few adjustments can pull the ceiling lower. A declining-market flag on the property lowers it by 5 points. Philadelphia lines carry a ceiling 10 points lower. Say your rental sits in a market flagged as declining and would otherwise qualify at 75%. The working ceiling drops to 70%, and the line shrinks with it.
When a first-lien line goes above $500,000, the 65% ceiling governs. That is why a bigger line does not always mean a bigger check. A property that supports a $500,000 line at 75% LTV may support less cash at 65% on a larger request. Size the request to the tier you are in. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Which Limit Binds First: Equity, Dollar Cap, Rent, or Credit?
Four things can cap your line, and only one of them is the binding one on any given file.
| Constraint | When it binds |
|---|---|
| Equity (value × ceiling) | Lower-value properties, where the percentage runs out first |
| Dollar cap | High-value properties, where $500,000 or $1,000,000 arrives before the percentage does |
| Rent coverage | Modest rents against a large line |
| Credit tier | Scores below 740, which lower the percentage |
Picture an owner with a very valuable rental and a 740 score. The percentage would allow more than $500,000, but the standard-tier dollar cap stops the line there. Moving above it means stepping into the 65% tier. Now picture a lower-value rental. The percentage runs out well before any dollar cap matters, so equity is the limit.
The rent test is the one most owners overlook. The next section covers it.
How the Rent Test Limits the Line
The rent qualifies the line, not your personal income. No traditional personal-income documentation, W-2s, pay stubs, or debt-to-income ratio come into it, subject to lender guidelines. That is the point of a DSCR line.
The test is gross monthly rent divided by a qualifying payment. A common minimum is 1.10x. The qualifying payment is a stress payment, a fully amortizing principal-and-interest payment on the entire credit limit at the start rate plus 2 percentage points. It is not a real payment you will make. Taxes and insurance are not part of it.
Here is the catch. The test runs on the whole line, not on what you draw. A $500,000 line is tested as if the full $500,000 were fully borrowed and repaying. A bigger line raises the qualifying payment, so a larger request can fail the rent test where a smaller one on the same property passes.
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. On a two-to-four-unit property, at most one unit can be vacant.
So a property with plenty of equity can still produce a smaller line than the percentage allows. The fix is usually to request less, not to argue the math. The rate and the pricing terms come with the lender’s disclosures, and the lender’s own calculation governs every file.
What If the Owner Has a Mortgage on the Property?
Then the structure changes, and so does the ceiling. With a mortgage you keep, the line becomes a standalone second lien. The subtraction step is no longer zero, because the first mortgage balance counts inside CLTV.
| Item | No mortgage | Keeps a mortgage |
|---|---|---|
| Lien position | First lien | Second lien |
| Subtraction | Nothing | First mortgage balance |
| Ceiling | Up to 75% LTV | Up to 70% CLTV |
| Credit floor | 700 | 720 |
| Binding constraint | Tier, dollar cap, rent | Equity left after the first mortgage |
A second-lien line tops out at 70% CLTV at a 720 score or better, on lines up to $500,000. Below 720 there is no second-lien tier. A first lien exists only on a rental with no mortgage at all, so “nearly paid off” does not count. On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation.
The Dollar Rules: Minimums, Draws, and Terms
Lines start at $50,000. 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 draw period is 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable.
That structure suits an owner who wants to stage cash, such as a rehab followed by a down payment on the next rental. It does not suit someone who wants a small standby line, because most of the line is drawn up front. Interest accrues on what is drawn.
How the Property Gets Valued
Value drives everything above, so the valuation path matters. Lines up to $400,000 use an automated valuation (confidence score of 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.
NerdWallet notes that a line on an investment property can be had but comes with strict requirements, that multiple appraisals may be required, and that fewer lenders offer one. A recent rehab is the classic case where a full appraisal can serve you better than an automated number, because an automated model may not see the work.
A full title policy applies on a first lien. That is a different file from an owner-and-encumbrance report, which only applies to smaller second liens.
Who This Does Not Fit
This line is only for a non-owner-occupied one-to-four-unit rental. It is never written on your own home or a second home. A paid-off primary residence needs a different, owner-occupied product.
Other limits to know:
- Seasoning: 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).
- Property types: Single-family, PUD, townhome, two-to-four units, and condominiums are eligible. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, and a property listed for sale in the prior 2 months are not.
- Borrowers: US citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
- Exposure: At most 5 loans or $2,500,000 per borrower with the program.
- Credit history: No 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu.
You can hold title in an LLC, subject to lender program eligibility. The members sign as guarantors. That is different from a bank’s personal-income investment HELOC, which is a separate product underwritten on your income and debt-to-income ratio.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is the broker. It places the line through a wholesale lender, and the lender underwrites it.
Line, Loan, or Cash-Out Refinance?
Which one fits depends on how you will use the cash.
| Item | DSCR HELOC (first lien) | DSCR cash-out refinance | Personal-income investment HELOC |
|---|---|---|---|
| Structure | Revolving line | New first-lien loan | Revolving line |
| Reviewed on | Rent | Rent | Your income and DTI |
| Best for | Staged draws | One large need | Strong W-2 earners |
| Adds a payment to a free-and-clear rental | Yes | Yes | Yes |
The CFPB’s explanation of a home equity loan versus a line describes the core split: a loan is a lump sum, a line is repeat borrowing up to a maximum. For a single large need on a property with no mortgage, a cash-out refinance can be the cleaner fit. See the complete DSCR loans guide for the broader picture.
The trade-off is honest. A line suits an investor drawing in stages. A refinance suits one big draw. Both put debt on a property that had none, which lowers cash flow.
The Risks to Weigh
Debt-free is a strong position. You are choosing to give some of it up.
- A new payment. A first-lien line adds a payment to a property that had none. Cash flow drops.
- Variable rate. Your payment can rise after the draw period and during it.
- Freezes. The CFPB says lenders may reduce or freeze a line if the home’s value falls significantly. A line is not a guaranteed ten-year supply of cash.
- Collateral. If you fall behind, the lender can take the property.
- Business purpose. 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.
Key Terms Defined
- DSCR: Debt-service coverage ratio, which is the rent divided by the qualifying payment.
- LTV: Loan-to-value, the loan amount divided by the property’s value.
- CLTV: Combined loan-to-value, the first mortgage balance plus the new line, divided by value.
- First lien: A loan with first claim on the property, which is the position a line takes when there is no mortgage.
- Draw period: The stretch when you can borrow from the line, here 5 years interest-only on the drawn balance.
- Stress payment: A fully amortizing payment on the whole line at the start rate plus 2 points, used only for the rent test.
Frequently Asked Questions
What is the maximum line on a rental with no mortgage?
Typically 75% of value at a 740 score or better, on lines up to $500,000, and 70% at 700 to 739. Lines above $500,000 run to $1,000,000 at a 65% ceiling. The rent test and the valuation can set a lower number, subject to underwriting, unless three months of rent receipts support a lease above market.
Can the rent test shrink my line?
Yes. Rent must cover a stress payment on the entire line at a 1.10x minimum. A larger request raises that payment, so a smaller line can pass where a bigger one fails. The lender’s own calculation governs.
How long must I 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 I use this on my own paid-off home?
No. The line is only for non-owner-occupied one-to-four-unit rentals. A primary residence or second home needs a different product, and a primary-residence HELOC is a separate owner-occupied line.
Can I hold title in an LLC?
Yes, subject to lender program eligibility. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
