The Quick Read: The largest second lien on a rental is set by the lower of two ceilings: the combined loan-to-value room left after your first mortgage, and the program’s dollar cap. Through select programs in Lendmire’s wholesale network, a rent-qualified second lien typically reaches 70% combined loan-to-value (CLTV) on lines up to $500,000, subject to underwriting.
- Maximum line = (value × 70%) − first-mortgage balance, then limited by the $500,000 cap.
- A 740 score and a 720 score both reach 70% CLTV on a second lien, so a higher score adds no leverage.
- The rent qualifies the line at a 1.10x minimum on a stress payment over the whole credit limit. The file needs no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines.
- The line is a standalone second lien, or a standalone first lien on a rental with no mortgage. It is never a third lien.
- An LLC can stay on title, subject to program terms.
What a DSCR HELOC Is
A DSCR HELOC is a revolving line of credit on a non-owner-occupied one-to-four-unit rental. The CFPB’s HELOC booklet describes a HELOC as a loan you can borrow against, repay and borrow against again, with the home as collateral. This product follows that pattern on investment property, with one difference: the rent qualifies it, not the owner’s paycheck.
Across the wholesale network, the line comes in two lien positions:
- A standalone second lien behind the first mortgage you keep.
- A standalone first lien on a rental with no mortgage.
It is never closed together with a purchase. It is never a line on your own home or a second home. The first mortgage stays untouched, which is why many landlords prefer it to a cash-out refinance.
Bank-style investment HELOCs are a different product. Those usually qualify the owner on personal income, debt-to-income and credit. NerdWallet’s explainer on HELOCs for investment property notes the lender pool is smaller than for a primary home and qualification is strict. That matches what files show. Few desks write investment lines, so each desk’s rules matter more. The complete DSCR loans guide covers the rent-based family in full.
How the Maximum Second Lien Is Calculated
The maximum comes from three steps. Skip one and the number is wrong.
1. Find the CLTV cap. On a second lien the ceiling is 70% CLTV, at a 720 credit score or better. CLTV is the first-mortgage balance plus the new line, divided by value. The line is counted at its full limit, not the drawn balance. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
2. Subtract the first mortgage. Multiply value by 70%, then take away the first-mortgage balance. What remains is the room.
3. Apply the dollar cap. Lines run from $50,000 to $500,000. The smaller of the equity room and the cap governs.
The table shows how the first-mortgage balance moves the answer. Every row is a percentage of value, so it applies to any property.
| First mortgage, % of value | Room under 70% CLTV | What binds |
|---|---|---|
| 30% | 40% of value | The $500,000 cap on higher-value homes |
| 50% | 20% of value | Equity room |
| 65% | 5% of value | Equity room; may fall under the $50,000 floor |
| 70% or more | None | No second lien available |
Run the reverse for a target. To reach a $500,000 line, value must be at least the first-mortgage balance plus $500,000, divided by 0.70. A cheaper property with a smaller first mortgage can still hit the cap. A pricey one with a large first mortgage cannot.
Three adjustments shave the ceiling. A declining-market flag lowers it 5 points. Philadelphia lines carry a ceiling 10 points lower. Insurance has to cover both liens, with flood coverage where required.
The first-lien path differs. On a rental with no mortgage, the ceiling is loan-to-value (LTV), not CLTV:
| Credit score | Line up to $500,000 | Line above $500,000 to $1,000,000 |
|---|---|---|
| 740 or better | 75% LTV | 65% LTV at 720 or better |
| 720 to 739 | 70% LTV | 65% LTV |
| 700 to 719 | 70% LTV | Not offered |
All figures are ceilings, not offers, and subject to underwriting. Lines above $500,000 exist only as a first lien. A second lien never goes past $500,000.
How the Rent Test Treats the Line
The coverage test is DSCR: gross monthly rent divided by a qualifying payment. The minimum is 1.10x. The qualifying payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. That is a stress payment, and it covers the whole line, not just what you draw.
Bigger lines therefore need more rent. A line sized to the cap is tested as if fully drawn.
On a second lien, how the first-mortgage payment enters the test is the lender’s call. The lender’s own coverage calculation governs, so ask your broker how the specific desk treats it before you count on a number.
Rent is the lesser of the appraiser’s Form 1007 market rent or the lease. A lease above market counts only with three months of receipts. A lease in place is required, and a two-to-four-unit property may have at most one vacant unit.
Draw Rules and Line Structure
Draw rules decide whether this behaves like a revolving line or a funded loan.
- Draw period: 5 years, interest-only on the drawn balance.
- Repayment period: 25 years, fully amortizing.
- Maturity: 30 years.
- Rate: variable. The rate and pricing terms come with the lender’s HELOC disclosures.
- At closing: at least 80% of the line is drawn, and never less than $50,000.
- Later draws: at least $5,000 each.
An investor wanting a mostly undrawn line should plan around the 80% draw at closing. It works more like a funded second with a small undrawn reserve. The payment steps up when the draw period ends and principal begins. Rent that covered interest-only comfortably can cover the amortizing payment more thinly, and the variable rate adds risk. Size the line to what rent can carry through both periods.
What Else Limits Your Line
Credit. A second lien needs 720. A first lien needs 700. The score is the lender’s own report. There must be no 30-day mortgage late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu.
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).
Valuation. Lines 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 need a full interior appraisal on Form 1004, 1073 or 1025. Appraisal waivers are not accepted. An automated value may miss a recent rehab, and a full appraisal may support a higher value, depending on comps and underwriter review.
Title. 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.
Reserves and cash to close. None required.
Exposure. At most 5 loans or $2,500,000 per borrower with the program.
Borrowers. U.S. citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Property and Vesting: Where the Rule Breaks
The formula holds on most files. These are the cases where it doesn’t.
Eligible types. Single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots up to 10 acres. Leverage tiers govern every property type.
Excluded. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, mixed-use, a property with a solar lien, and a property listed for sale in the prior 2 months.
LLC title. The LLC can stay on title, for investment property only. Members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line need not match the first-mortgage borrowers.
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, and the CFPB’s Regulation Z page on exempt credit addresses the business-purpose question.
Your first mortgage note. Not every first-mortgage note welcomes a junior lien. Pull the note and the title report early, since a lien-position surprise late in review can sink the file.
First-time investors. There is no equity to borrow against until a rental is owned and seasoned.
Availability. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. The states are Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington.
What Makes the Best Program for Your Situation?
No single program wins every file. Lendmire is a mortgage broker, not a lender. It matches a scenario to wholesale lenders in its network, and the program that fits depends on property type, credit profile, leverage need and documentation. Judge each option against one checklist.
| Criterion | Why it matters |
|---|---|
| CLTV ceiling for your lien position | Sets the equity room |
| Dollar cap | Binds on higher-value properties |
| Review basis | Rent coverage versus personal income |
| Title rules | Decides whether the LLC stays on title |
| Draw rules | Share drawn at closing and later minimums |
| Valuation path | Automated value with inspection, or full appraisal |
| Exposure caps | Limits on loan count and total dollars |
Rank by what your file can pass, not by the biggest headline number. A program with a high ceiling that excludes your property type is not the best program for you.
Second Lien, First Lien, or Cash-Out Refinance?
When the second lien can’t reach your number, you have four paths.
| Situation | Path | Trade-off |
|---|---|---|
| Low first mortgage, enough equity room | Second-lien DSCR HELOC | 70% CLTV, $500,000 cap |
| No mortgage on the rental | Standalone first-lien line | Up to 75% LTV, larger lines drop to 65% |
| Need more than the cap allows | DSCR cash-out refinance | Replaces the existing first mortgage |
| Small equity room | Smaller second lien | Must still meet the $50,000 floor |
A bank’s personal-income HELOC follows that bank’s own rules, usually with a debt-to-income test. Those rules are not this program’s. A cash-out refinance is its own program with its own leverage rules, and it replaces your first mortgage instead of sitting behind it. If a low first mortgage is the asset, keep it and use a second. Lendmire’s piece Waiting Out a HELOC Freeze vs a New Second Lien on a Rental walks through that decision.
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.
What to Prepare
A clean file leaves fewer preventable gaps. Bring:
- The current lease and, if rent exceeds market, three months of receipts.
- The current first-mortgage statement, so CLTV ties out.
- Entity documents, if the LLC holds title.
- Proof of hazard insurance covering both liens, plus flood where required.
- Settlement statement or title history to document seasoning.
- The unit count and, for condominiums, the association paperwork.
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.

Frequently Asked Questions
What is the maximum second lien on a rental?
Through select programs, a second lien reaches $500,000 at 70% CLTV with a 720 score or better, subject to underwriting. The real maximum is usually lower. The first-mortgage balance eats into the 70% room before the dollar cap matters.
Does a higher credit score raise the second-lien limit?
No. A 740 and a 720 both reach 70% CLTV. Below 720 there is no second-lien option. A stronger score helps the file but does not unlock more leverage on a second lien.
Can an LLC hold title?
Yes, on investment property, subject to program terms. Members sign as guarantors, and a title holder who is not a borrower signs the non-borrowing owner acknowledgment and the security instrument.
Is there a seasoning requirement?
Yes.
Why does an owner with plenty of equity still get a small line?
The first mortgage uses up CLTV room before the new line is sized. An owner whose first mortgage is near 65% of value has only about 5% of value in room under a 70% ceiling, which may fall below the $50,000 floor.
