The Quick Read: A rental with 30% equity sits right at the 70% combined loan-to-value ceiling on a second-lien line, so the right program turns on whether a first mortgage exists, because that decides if any room is left to borrow.
- With a first mortgage in place and 30% equity, the combined leverage test leaves no room on a second-lien line, subject to underwriting.
- A paid-off rental can take a first-lien line instead, with leverage of up to 75% at the top credit tier through select programs.
- The rent qualifies the line at a 1.10x minimum, measured on the entire credit limit and not just the amount drawn.
- A higher credit score does not buy more second-lien leverage. It only decides eligibility.
- The best program for your situation depends on lien position, credit tier, rent coverage, and the size of the line you actually need.
What Does “30% Equity” Actually Mean Here?
Most investors who search this phrase mean one of two things, and the two lead to different answers. Equity today is what you own right now. Equity after the line is what you would still own once the new line is added to every other lien.
A line on a rental is a revolving line of credit secured by the property. A CFPB explainer on home equity lines describes the product as open-end credit you can borrow against repeatedly. A DSCR version adds one twist. The rental’s income qualifies the line, and the owner’s personal income is never calculated.
Lendmire is a mortgage broker. It places these files with select wholesale lenders in its network, and those lenders decide eligibility. The mechanics below reflect what these programs typically require, subject to lender guidelines.
| Your “30% equity” means | What it does to the line |
|---|---|
| 30% equity today, first mortgage kept | Second-lien room is zero at a 70% CLTV ceiling |
| You want to finish with 30% equity | The first mortgage plus the new line must stay at or under 70% |
| Paid-off rental, no mortgage | A first-lien line is possible, up to 75% LTV at the top tier |
For a complete walkthrough of how these loans work across the board, see Lendmire’s complete DSCR loans guide.
How the Leverage Math Works
The ceiling is the first thing to test, because it is the constraint that usually binds. Combined loan-to-value, or CLTV, adds the first mortgage balance and the new line, then divides by the property’s value. A plain-language CLTV definition from Motley Fool says the same thing. The test runs on the full credit limit, not the drawn balance.
On a second-lien line, most programs we place files with cap CLTV at 70%. The line must be at least $50,000 and runs up to $500,000, subject to underwriting. The formula is simple. Take 70% of value, subtract the first mortgage balance, and you have the most the line could be.
Here is how that looks as a share of value:
| First mortgage (% of value) | Equity today | Room under 70% CLTV |
|---|---|---|
| 40% | 60% | Up to 30% of value |
| 55% | 45% | Up to 15% of value |
| 65% | 35% | Up to 5% of value, usually too small to use |
| 70% | 30% | — |
| 75% | 25% | Over the ceiling |
The row at 70% is the one this article is about. An owner with exactly 30% equity and a first mortgage has nothing left to borrow on a second-lien line.
The margin problem is worth planning for. A property sitting exactly at the ceiling has no cushion. If the valuation comes in a little under your expectation, CLTV moves above 70%, and the file stops working even if the rent is strong. Investors who want a thin-equity line should build a buffer before ordering a valuation, either by paying the first mortgage down or by waiting for value to rise.
Does a better credit score unlock more room?
No. On a second lien, a 740 score and a 720 score both reach the same 70% CLTV. A score of 720 is the minimum, and below it there is no second-lien option on this program. Score buys eligibility here, not extra leverage.
The Paid-Off Rental Path
A rental with no mortgage can take a standalone first-lien line. Leverage here is measured as LTV, since no other lien exists. Through select programs, a first lien up to $500,000 reaches 75% LTV at 740 or better. It reaches 70% at 700 to 739. The first-lien credit floor is 700. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Larger first-lien lines run up to $1,000,000, and those are capped at 65% LTV at 720 or better. A paid-off rental therefore keeps at least 25% of its value out of reach, and 35% on the largest lines. Investors sometimes read “30% equity” as a floor they can clear easily. It is closer to the ceiling than the floor. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
What the Best DSCR HELOC Program With 30% Equity Really Looks Like
The best program for your situation depends on four things: lien position, credit tier, rent coverage, and the line size you need. No single program wins across all four. A broker that shops several wholesale lenders can match the file to the program that fits it, which is the practical edge of working through one.
For a 30%-equity owner, the honest sorting looks like this.
- First mortgage in place, 30% equity or less: a second-lien line is not workable. A cash-out refinance, or waiting for more equity, is the usual alternative.
- First mortgage in place, 40% equity or more: a second-lien line may fit if the remaining room clears the $50,000 minimum, and it lets you keep the existing first mortgage untouched.
- No mortgage: a first-lien line may fit, with the 75%, 70%, and 65% tiers above.
How the Rent Test Works
The program qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. No traditional personal-income documentation, W-2s, or pay stubs are used, and there is no personal debt-to-income calculation. The rent, the lease, the credit report, and the valuation are all documented.
The minimum DSCR is 1.10x. That figure is gross monthly rent divided by a qualifying payment. The qualifying payment is a fully amortizing payment on the entire credit limit, computed at the start rate plus 2 percentage points. It is a stress payment, built to be conservative. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
That detail trips up investors. If you plan to draw a third of a line, coverage is still tested on the whole line. A bigger line can fail the test even when your actual drawn balance would have passed.
On a second lien, the lender’s own coverage calculation governs whether the first mortgage payment is part of the qualifying payment. Programs differ on this point. A rental that clears 1.10x easily as a standalone first lien may sit close to the line once a first mortgage is counted. Ask the lender how it treats the existing first mortgage before ordering a valuation.
Rent is the lesser of the appraiser’s market rent (Form 1007) or the lease. A lease above market rent counts if you can show three months of receipts. A lease must be in place, and a two-to-four-unit property may have at most one vacant unit.
How the Line Is Drawn and Repaid
The draw period runs 5 years, with interest-only payments on the drawn balance. A 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable. The CFPB booklet on home equity lines notes that lines of this kind typically carry variable pricing, so the payment can move with the balance and the market.
At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each. This structure suits an investor with a defined use, such as a down payment, a rehab, or a bridge in a BRRRR strategy. It suits a “just in case” line less well, since most of the money is drawn up front.
Tax treatment can depend on how the funds are used and how the property is held. Borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
The Valuation, Title, and Seasoning File
Lines up to $400,000 can 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.
Title work scales with the line. A full title policy applies on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report.
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, subject to underwriting. Credit history matters, though. Programs of this type typically look for no 30-day mortgage late in the last 12 months and 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu.
Where the General Rule Breaks
Several edge cases change the answer.
- Property types. Single-family, PUD, townhome, two-to-four units, and condominiums are eligible property types. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, and mixed-use are not. A property listed for sale in the prior 2 months or carrying a solar lien is also out.
- Market flags. A declining-market flag lowers the leverage ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
- Borrower type. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number can qualify. Foreign nationals and ITIN borrowers are not eligible on this program.
- Entity title. Vesting in an LLC is allowed on investment property, subject to lender program eligibility. The members sign as guarantors. Bank-style lines on rentals often want individual title instead, which is one reason investors look at the DSCR route.
- Exposure. A borrower can carry at most 5 loans or $2,500,000 with the program.
- Footprint. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Another edge case is the label itself. “DSCR HELOC” is an informal phrase. Some lenders use it for a closed-end second mortgage, or even a first-lien cash-out, so ask what the underwriting basis is and whether the line is revolving. NerdWallet’s overview of HELOCs on investment property makes a related point: investment-property limits run lower than on a primary home, and not every lender offers the product at all.
DSCR HELOC or Cash-Out Refinance at 30% Equity?
This is a genuine toss-up for some borrowers. A line lets you keep a low-cost first mortgage. A cash-out refinance replaces it. But the line’s 70% CLTV ceiling can leave less to borrow than a refinance would.
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance | Personal-income investment HELOC |
|---|---|---|---|
| Reviewed on | Rent, 1.10x stress test | Rent coverage under that program’s rules | Credit, DTI, and equity |
| First mortgage | Kept | Replaced | Kept |
| Leverage | Up to 70% CLTV | Up to 75% LTV on a standard rental | Up to 70% CLTV on that program |
| LLC vesting | Allowed | Per program | Typically not allowed |
| Best fit | Real room under the cap | Thin room, need more cash | W-2 borrower, individual title |
The cash-out column describes that program’s own rules, through select programs, and the personal-income column describes that separate product. At 30% equity with a first mortgage, the refinance usually delivers more usable cash, at the cost of giving up the existing first mortgage. If the existing first mortgage is the asset you want to protect, the real question is how much equity you can build before the line is worth pursuing. Lendmire’s piece Best Investment Property HELOC Program With Only 15 Percent Equity in the Home covers the personal-credit side of this tradeoff.
Who This Is Not For
The line is not a fit for several profiles.
- Owners whose combined leverage already sits at or above 70%.
- Borrowers under a 720 score who want a second lien, or under 700 who want a first lien.
- Rentals that fail the 1.10x test on the full credit limit.
- Anyone who wants a line on their own home or a second home. This product is never offered on an owner-occupied property.
- Borrowers who expect a small draw with little documented, since most of the line is funded at closing and the file still needs a lease, valuation, and credit review.
Pre-Application Checklist
Gather these before you talk to a broker.
1. The current first mortgage balance and a recent value estimate.
2. The lease, and the last three months of rent receipts if rent exceeds market.
3. Your credit score tier and any recent mortgage lates.
4. The date you bought or last refinanced, and the date title was recorded.
5. How the property is titled and whether an LLC is involved.
6. The size of the line you need and what you plan to do with it.
7. Whether the property is listed, in an excluded type, or carries a solar lien.

Common Mistakes at Thin Equity
- Treating 30% equity as proof of room, when it is already the ceiling.
- Sizing the line to the amount you plan to draw instead of the full limit that gets tested.
- Ordering a valuation with no cushion.
- Assuming a higher score will lift the second-lien ceiling.
- Skipping the question of how the lender treats the first mortgage payment in coverage.
Frequently Asked Questions
Can I get a DSCR HELOC with exactly 30% equity?
Only if there is no first mortgage. With a first mortgage in place, 30% equity equals 70% combined leverage, which is the second-lien ceiling, so no room remains. A paid-off rental can use a first-lien line instead, subject to underwriting.
Does the line work with an LLC?
Yes, vesting in the owner’s LLC is allowed on investment property, 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 and the security instrument.
Do I need tax returns or W-2s?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Credit, the lease, title, and the valuation are still reviewed.
What if my rent is low?
The 1.10x test runs on the full credit limit, so a smaller line can pass where a larger one fails. A lease above market rent counts if you can show three months of receipts, and the lender’s own coverage calculation governs the result.
Next Step
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. Investors can reach the team at 828-256-2183 or request a quote. Programs change, and every file is underwritten individually.
A rental sitting at 30% equity is one valuation change away from either having room or having none, so the investors who plan well treat the 70% ceiling as the starting point, not the finish line.
