The Quick Read: If 30% equity means a first mortgage at 70% of value, you have no room for a line. A second-lien DSCR HELOC tops out at 70% combined loan-to-value (CLTV, meaning every loan on the property divided by its value), so that first mortgage already uses the full allowance. Room opens up only when the first mortgage sits well below 70% of value, for example at 40%.
- Your room is 70% minus your first mortgage as a share of value, so a first mortgage at 40% of value leaves about 30% of value for the line.
- The line must be at least $50,000 and no more than $500,000 as a second lien.
- Rent must cover a stress payment on the entire credit limit at 1.10x or better.
- A rental with no mortgage can take a first-lien line instead, with higher ceilings. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Why “30% Equity” Doesn’t Mean “Borrow 30%”
Equity is what you own today. The CLTV cap limits what you can owe after the new line is in place. Those are opposite sides of the same number.
The formula is simple. Yahoo Finance defines combined loan-to-value as all secured debt on the property divided by its value. For a DSCR HELOC, the new line counts at its full limit, not just the amount you draw.
If you have only 30% equity, your existing liens already sit at 70% of value, so a 70% ceiling leaves no room for a new line. Room opens up only when your existing liens sit below that ceiling, and the line can use only the gap between the two. The cap is built so that at least 30% equity stays in the property after the line closes.
Owners hear “70%” and assume they can pull out 70% of the value. They can only reach 70% of value in total debt.
How Much Room Do You Actually Have?
Room is the CLTV ceiling minus the first mortgage, both measured as a share of the property’s value. Across the wholesale network where Lendmire places these files, a second-lien line on a rental typically carries a 70% CLTV ceiling at a 720 score or better, subject to underwriting.
| First mortgage, % of value | Room left, % of value | Read |
|---|---|---|
| 70% | 0% | No line fits |
| 60% | 10% | Thin; may fall under the minimum line size |
| 55% | 15% | Possible on higher-value rentals |
| 40% | 30% | Workable room |
| 30% | 40% | Strong room, capped at $500,000 |
The minimum line is $50,000. Room of 10% on a modest property can fall below that floor, so the percentage alone doesn’t settle it. Room of 15% works only if that slice of value clears the minimum.
A high score doesn’t buy more. There is no higher second-lien tier above 70% CLTV, and below a 720 score the second-lien tier isn’t available at all. If a lender flags the property’s market as declining, the ceiling drops by 5 points.
What Changes on a Rental With No Mortgage
A paid-off rental can take a standalone first-lien line, and the ceilings are different. These are loan-to-value (LTV) figures, since only one loan is involved.
- 740 or better: up to 75% LTV on lines to $500,000.
- 700 to 739: up to 70% LTV on lines to $500,000.
- Lines above $500,000, up to $1,000,000: 65% LTV at 720 or better. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
The first-lien floor is a 700 score. A first lien exists only on a rental with no mortgage. If you keep a first mortgage, the line is a second lien, with the 720 floor.
An owner with no mortgage doesn’t have 30% equity at all. They have close to all of it. For them, the question is the tier, not the thin cushion.
The Second Limit: Rent
Equity sets the ceiling. Rent can set a lower one. Both tests must pass.
The program qualifies the line primarily on property-level rental income covering the payment, subject to lender guidelines. There is no traditional personal-income documentation: no W-2s or personal income calculation. The minimum coverage is 1.10x: gross monthly rent divided by a qualifying payment.
That qualifying payment is principal and interest on the entire credit limit, run as fully amortizing at a stress rate set above the starting rate. Taxes and insurance are not part of it. 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, and a two-to-four-unit property may have at most one vacant unit.
Here is the catch. The test runs on the whole limit, not the drawn balance. A line you intend to draw lightly is still tested as if fully drawn.
Whether the first-mortgage payment joins the calculation on a second lien depends on the lender’s coverage calculation. Confirm on the file how the lender treats it. Any arithmetic you run yourself is illustrative, and the lender’s own calculation governs.
So which limit binds first? A rental with both a heavy first mortgage and soft rent can fall short on both tests at once. Work out both before you apply.
Think of two owners at the same 30% equity. One holds a low-balance first mortgage on a duplex with strong leases. The other holds a first mortgage near the cap on a single-family home with soft rent. The first owner may have real room on both tests. The second has none on either.
Why a Small Valuation Change Matters at This Threshold
At 30% equity you sit on the ceiling, so a small move in value shifts the answer. A modest drop in value raises your first mortgage as a share of value and shrinks your room by about the same amount. A modest rise does the opposite.
The valuation path depends on line size:
- Lines up to $400,000: an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal.
- Lines above $400,000: a full interior appraisal.
Appraisal waivers are not accepted. NerdWallet notes that investment-property lines can involve multiple appraisals, so ask early what the file will require.
How the Line Works Once It’s Open
A DSCR HELOC is a revolving line secured by your rental. It is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never closed together with a purchase, never a third lien, and never a line on your own home.
The draw rules are specific:
- 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.
- Later draws are at least $5,000 each.
- The draw period is 5 years, interest-only on the drawn balance.
- Repayment then runs 25 years, fully amortizing, for a 30-year maturity.
- The rate is variable.
The first mortgage stays in place. That matters if you hold a low-cost first mortgage you don’t want to disturb. The tradeoff is a second payment, and the property secures both loans. The CFPB warns that falling behind on a home equity line can cost you the property.
When 30% Equity Isn’t Enough: A Decision Path
If your first mortgage already consumes the 70% ceiling, you have four honest options.
1. Pay down the first mortgage. Every point of first-mortgage balance you retire becomes a point of room.
2. Wait for value or a new valuation. Rising value lowers your first-mortgage share. A fresh valuation is the only way to prove it.
3. Compare a cash-out refinance. A DSCR cash-out refinance replaces the first mortgage instead of sitting behind it. On standard rentals, cash-out ceilings reach about 75% LTV, and about 70% on short-term-rental collateral, subject to program terms. The new payment must clear the rent test again, and you give up your existing first mortgage.
4. Skip it for now. If the room falls under the $50,000 minimum, the product doesn’t fit. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
| Factor | DSCR HELOC | DSCR cash-out refinance | Bank-style investment HELOC |
|---|---|---|---|
| Lien | Second lien, or first on a paid-off rental | Replaces the first mortgage | Usually a second lien |
| Reviewed on | Rental income | Rental income | Personal income |
| Keeps your first mortgage | Yes | No | Yes |
| Lender pool | Select programs | Wide | Limited |

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.
Across the network, the first-mortgage balance and the rent test are the two numbers every file turns on. Lendmire’s complete DSCR loans guide explains the wider program family.
Key Terms Defined
DSCR (debt-service coverage ratio): gross monthly rent divided by the qualifying payment. This program asks for 1.10x or better.
CLTV (combined loan-to-value): every loan secured by the property, including the new line’s full limit, divided by the property’s value.
Lien position: whether a loan is paid first or second if the property is sold. A second lien sits behind the first mortgage.
Draw period: the first 5 years, when you pay interest only on the balance you have drawn.
Stress payment: the payment used for qualifying, calculated on the whole credit limit at a rate above the starting rate. It is not the payment you make.
Frequently Asked Questions
Can I get a DSCR HELOC if my first mortgage already uses 70% of the value?
Not as a second lien. The ceiling is 70% CLTV, so there is no room left above it. Paying down the first mortgage, a higher valuation, or a DSCR cash-out refinance are the usual alternatives, each subject to underwriting.
Does a higher credit score raise how much I can borrow?
Not on a second lien. A 720 score or better reaches the top tier, which is 70% CLTV, and there is no tier above it. On a first lien, a 740 score does reach 75% LTV, compared with 70% LTV from 700 to 739. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Is the rent test run on what I draw or on the whole line?
On the whole credit limit. The qualifying payment is principal and interest on the full line at a stress rate, so a lightly drawn line is still tested as fully drawn. Taxes and insurance aren’t part of that payment.
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). Both must be satisfied before a file moves forward.
Can my LLC hold the property?
Yes, on an investment property, depending on program guidelines. The members sign as guarantors, and a title holder who isn’t a borrower signs an acknowledgment. The borrowers on the line don’t have to be the borrowers on the first mortgage.
What to Do Next
Start with two numbers: your first mortgage as a share of the property’s value, and the rent on the lease. If the first number is under 70% and the room clears $50,000, the rent test is next.
If you are considering a home equity line on a rental property and want to see how the numbers work, Lendmire can help you compare DSCR HELOC options based on the property, the rent, the equity available, credit profile, combined leverage, and your goals.
