The Quick Read: A DSCR HELOC line equals the rental’s value times 70% combined loan-to-value, minus the first mortgage balance, capped at $500,000 on a second lien, subject to underwriting. A smaller first balance leaves more room for the line, because the first counts against the ceiling. The line has to reach the $50,000 minimum, and the rent has to cover the qualifying payment at 1.10x or better.
- Second-lien ceiling: up to 70% CLTV at a 720 credit score or better, on lines from $50,000 to $500,000.
- The coverage test runs on the entire credit limit, not only the amount drawn.
- The first mortgage stays in place, and the new line prices only the new money.
- Everything is subject to underwriting. This is not a commitment to lend.
Lendmire is a broker. It arranges these lines through a wholesale lender in its network. Program terms change, and every file is underwritten individually.
The Formula in Plain Words
Value times the maximum CLTV gives the total debt the property can carry. Subtract the first mortgage balance and any other recorded lien. What is left is the largest line the property can support.
CLTV means combined loan-to-value. It counts every lien on the property, including the new line, divided by the property’s value. Yahoo Finance’s CLTV explainer makes the same point: a lender counts both the existing first mortgage and the requested amount. That means the new line counts in the calculation even before it has been funded.
Here is the part that trips people up. Total equity is not borrowable equity. The ceiling is a percentage of value minus liens, so what you can borrow is always less than what you own outright.
Worked Examples: Same Property, Different First Balances
Run the numbers on one rental, using ratios instead of dollars. Say the first mortgage sits at about 40% of value. Under a 70% CLTV ceiling, that leaves roughly 30% of value for the line. A first at about 50% leaves roughly 20% of value. A first near 55% leaves about 15%. All three are subject to underwriting and the $500,000 cap.
| First mortgage vs. value | Room under 70% CLTV | What happens |
|---|---|---|
| About 40% | About 30% of value | Line likely clears the $50,000 minimum |
| About 50% | Up to about 20% | Depends on property value |
| About 55% | About 15% | Needs a higher-value property to reach $50,000 |
| 70% or more | None | No second-lien room |
The minimum line matters as much as the ceiling. If value times 70% minus the first balance falls under $50,000, a second lien may not fit. A modest rental with a mid-sized first can land in that gap. A higher-value property with the same percentage balance usually will not.
Why a Low First Lien Is the Asset to Protect
An investor with a low first mortgage holds terms that a cash-out refinance would erase. A cash-out replaces the first mortgage, so the borrower gives up those terms. The second-lien line leaves the first alone and prices only the new money. The tradeoff is combined leverage: the second lien caps total debt at 70% CLTV.
This is the core decision. Is the first mortgage worth keeping, and does the new money fit under the ceiling? If both answers are yes, a second lien is the cleaner route.
How the Line Qualifies: Rent, Not Personal Income
The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. There is no traditional personal-income documentation: no W-2s, pay stubs or debt-to-income ratio. The minimum DSCR is 1.10x, which is gross monthly rent divided by the qualifying payment.
The qualifying payment is a fully amortizing payment on the entire credit limit at a stress rate above the start rate. That means a $500,000 line is tested as if fully drawn. Taxes and insurance are not part of that qualifying payment. A larger line therefore needs more rent behind it, even if the owner plans to draw less.
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. A two-to-four-unit property may have at most one vacant unit.
On a second lien, how the lender treats the first-mortgage payment in the coverage calculation is worth confirming before you move forward. The lender’s own calculation governs.
For the broader mechanics behind coverage ratios, see Lendmire’s complete DSCR loans guide.
Credit Tiers and What They Change
On a second lien, 720 is the floor and 70% CLTV is the ceiling. Going from 720 to 760 buys no extra leverage, because the second-lien lane has one tier. Below 720, there is no second-lien cell. For a borrower who keeps a first mortgage, that score floor is the obstacle, not the lien.
The mortgage history rules are straightforward. There can be no 30-day late in the last 12 months. At least 48 months must have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu.
The First-Lien Lane Does Not Apply Here
A first lien exists only on a rental with no mortgage. It reaches 75% LTV at 740 or better and 70% LTV from 700 to 739 on lines to $500,000. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. None of that applies to an investor keeping a first. It is mentioned so the figures are not mixed up. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Do not confuse this with the personal-income investment-property HELOC, which is a different program qualified on the borrower. Its figures differ and do not carry over.
Where the Number Gets Smaller
Several things can shrink the line below the formula’s answer:
- Other liens. A prior second lien, tax lien or recorded line comes out of the same 70% budget.
- Declining-market flag. It lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
- Valuation. The lender uses current value, not purchase price. A low valuation shrinks room dollar for dollar.
- Portfolio cap. A borrower can have at most 5 loans or $2,500,000 with the program. A large book can hit that before the equity runs out.
- First mortgage documents. They must allow a junior lien. Read the note and security instrument before applying.
- Property type. Rural-designated property, row homes, condotels, leaseholds, and a property listed for sale in the prior 2 months are outside the program.
Seasoning belongs here too. 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).
Draws, Repayment and the Closing Draw
The structure is a 5-year interest-only draw period on the drawn balance, then a 25-year fully amortizing repayment period, with a 30-year maturity. The rate is variable. 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.
This changes how to think about size. You are not opening a large line and leaving most of it idle. Size the line to the money you intend to use now. The CFPB’s HELOC explainer describes the general idea of a revolving line with a draw period. This program’s own draw and repayment terms are the ones above.
Valuation and Title
Lines up to $400,000 use an automated valuation with a confidence score of 85 or better plus a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted.
Title follows the line size. A second lien above $400,000 needs a full title policy. A smaller second lien uses an owner-and-encumbrance report.
Second Lien vs. Cash-Out Refinance
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Structure | Revolving line, variable rate | Term loan |
| Combined leverage | Up to 70% CLTV | Set by that program |
| Best fit | Low first worth keeping | First has no value to keep |
If the first mortgage is expensive or near the ceiling already, a cash-out may do more.
Key Terms Defined
- CLTV: Combined loan-to-value, meaning all liens on the property divided by its value.
- Second lien: A loan recorded behind the first mortgage, paid in addition to it.
- DSCR: Debt service coverage ratio, meaning gross monthly rent divided by the qualifying payment.
- Draw period: The 5-year window when the drawn balance is interest-only.
- Stress payment: A fully amortizing payment on the whole line at the start rate plus 2 points.
A Note on Equity and Taxes
NerdWallet notes that HELOCs on investment properties come with stricter requirements and limited availability, which is why the lender pool is smaller than on a primary home. 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.
Frequently Asked Questions
What is the most I can borrow on a second-lien DSCR HELOC?
Up to $500,000, and only if value times 70% minus the first balance reaches that figure. The ceiling is 70% CLTV at a 720 score or better.
Does the line count what I plan to draw or the full limit?
The full limit. The CLTV and the coverage test both run on the entire credit limit, not on a smaller amount you plan to use. Size the line to your need.
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 an LLC hold the rental?
Yes. Vesting in the owner’s LLC is allowed on investment property, subject to lender program eligibility. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Where is this program offered?
In 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
