The Quick Read: On an $860K rental with a $500K mortgage you keep, the program that fits is a standalone second lien that is reviewed on the rent, caps combined loan-to-value (CLTV) at 70% at a 720 credit score or better, and leaves room for a line of roughly twice the $50,000 minimum, subject to underwriting and the lender’s valuation. Which program is best depends on your credit profile, the valuation, and how much cash you need. On this property the leverage cap is usually the limit, not the rent.
- Your first mortgage is already about 58% of the $860K value, so a 70% CLTV ceiling leaves roughly 12 points of value for a new line.
- On a second lien at 720 or better, the 740+ and 720 to 739 tiers both top out at 70% CLTV, so the credit tier rarely changes the answer here.
- The rent must cover a stress payment on the entire credit limit, not only the amount you draw, at a minimum 1.10x coverage.
- Lines start at $50,000. If you need more than the window allows, the question becomes a cash-out refinance instead.
What a DSCR HELOC Is on a Rental You Keep Financed
A DSCR HELOC is a revolving line of credit secured by a rental you own. It is reviewed on the property’s rent instead of your personal income. When you keep your first mortgage, the line sits behind it as a standalone second lien. When the rental has no mortgage, the line is a first lien.
DSCR stands for debt service coverage ratio. It is the monthly rent divided by the monthly payment the lender tests. If you want the full background on how these loans work, the complete DSCR loans guide covers it from the ground up.
Here is what the program is not. It is not a line on your own home or a second home. It is not closed together with a purchase. It does not pay for the next property in the same transaction. It is a line on a one-to-four-unit rental you already own, available through select programs in Lendmire’s wholesale network.
Lendmire is a mortgage broker. It does not lend. It places files with wholesale lenders whose DSCR HELOC guidelines match the property and the borrower.
Because these are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The rent, the lease, the credit report and the valuation are all documented. What you skip is the tax returns, W-2s, pay stubs and debt-to-income calculation. The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
The $860K and $500K Math
Start with leverage, because it decides the file before anything else. CLTV is the balance of every loan on the property, first mortgage plus the new line, divided by the property’s value.
Your numbers, treating $860K as the value the lender accepts:
- Leverage today: $500K divided by $860K is about 58.1% before any line.
- The ceiling: through select programs, a second lien on an investment rental typically allows up to 70% CLTV at a 720 credit score or better, subject to underwriting.
- The room: the gap between 58.1% and 70% is about 12 points of value. That window is a bit more than twice the $50,000 minimum line.
- The smallest line: $50,000 adds about 5.8 points of CLTV and lands the file near 64%.
At least 80% of the line is drawn at closing, and never less than $50,000. A $50,000 line is therefore fully drawn on day one. Later draws must be at least $5,000 each.
You will notice the program also allows lines up to $500,000. That ceiling does not matter on this property. The CLTV cap runs out of room first.
Treat the $860K as an assumption. The lender’s valuation governs. A lower value shrinks your room, point for point, at a 70% ceiling. If the value drops far enough that the first mortgage alone nears 70%, there is no second-lien room at all.
Lendmire’s piece Can You Get a HELOC on a $860K Rental With a $500K Mortgage? walks through the same scenario from the eligibility side.
How the Coverage Test Treats the Line
The second test is coverage, and it is independent of CLTV. A property can pass one and fail the other.
The program requires at least 1.10x coverage. The lender divides gross monthly rent by a qualifying payment. That payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is a stress payment, built to test the property against a higher cost than you will start with.
Three details trip up new investors:
- The full limit counts. A larger line means a larger stress payment, even if you draw only part of it.
- The rent is the lesser of two figures. It is the appraiser’s market rent on Form 1007 or your lease. A lease above market counts only with three months of receipts. A lease in place is required.
- The first mortgage’s role is not published. Whether the first-mortgage payment joins the qualifying payment on a second lien is not stated in the program guidelines. The lender’s own coverage calculation governs. Some other second-lien programs combine both payments, so treat any quick calculation as illustrative.
Here is the practical consequence. A rental can look strong on its existing loan and still fall short once a line sits behind it. Size the line for the coverage test as well as the leverage test. A smaller second often clears when a larger one does not.
Which Program Is Best Here?
Across the wholesale network Lendmire works with, the second-lien lane has little tier variation. At 720 or better, both the 740+ tier and the 720 to 739 tier cap at 70% CLTV. Below 720, there is no second-lien option on this program. Your score either qualifies you or it does not.
The first-lien tiers are different. They run from 700 up, with 75% LTV at 740 or better, but they apply to a rental with no mortgage. They do not describe your file while the $500K mortgage stays in place. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
So the real choice is not between tiers. It is between structures. The best program for your situation depends on whether you want to keep the existing first mortgage and how much cash you need.
| Option | First mortgage | Reviewed on | Fit |
|---|---|---|---|
| DSCR HELOC (second lien) | Stays in place | Rent, credit, valuation | Smaller draw, keep the first |
| DSCR cash-out refinance | Paid off | Rent, credit, valuation | Larger cash need |
| Bank HELOC on personal income | Stays in place | Income, DTI, credit | Strong W-2 profile, individual title |
The last row describes bank-style investment HELOCs, not this program. Those lines lean on your personal credit, income and debt ratios. They often want the property in your own name or a revocable trust.
This program allows LLC vesting on investment property, per lender program requirements. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment. The borrowers on the line need not match the borrowers on the first mortgage.
The File: Credit, Valuation, Seasoning and Documents
Most programs in this lane want the same things. Here is what this one asks for, subject to underwriting:
- Credit: a 720 minimum on a second lien, using the lender’s own credit report.
- Mortgage history: no 30-day late in the last 12 months. Forty-eight months must pass since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- 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.
Valuation is the step that moves the numbers. Lines up to $400,000 can use an automated valuation (confidence score of 85 or better) plus a property inspection report. A full interior appraisal is the other path. Lines above $400,000 need the full appraisal. Appraisal waivers are not accepted.
Any line you could size on this property falls under the $400,000 line, so the lighter valuation path is available. Even so, the value that comes back is not a number you control. Plan the draw with some cushion.
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).
Expect to provide the lease, a current first-mortgage statement, hazard insurance that covers both liens, flood coverage where required, and the entity papers if an LLC holds title. Title work on second liens up to $400,000 is typically an owner-and-encumbrance report.
The rate on the line is variable. After the 5-year interest-only draw period, the line moves into a 25-year repayment period inside a 30-year maturity. The payment steps up when repayment begins. The rate and the pricing terms come with the lender’s disclosures.
Where the General Rule Breaks
The 70% CLTV figure is a ceiling. Several situations pull it lower or take the property out of the program.
| Situation | Effect on this file |
|---|---|
| Declining-market flag | Ceiling drops 5 points |
| Some locations (Philadelphia is one) | Ceiling 10 points lower |
| Rental listed for sale in prior 2 months | Not eligible |
| Solar lien on the property | Not eligible |
| Rural, row home, condotel, leasehold | Outside this lane |
| Two-to-four-unit property | At most 1 vacant unit |
Run the first two rows against your numbers. A 5-point reduction leaves about 7 points of value above your $500K mortgage. That barely clears the $50,000 minimum, which is about 5.8 points. A 10-point reduction leaves less room than the minimum line, so a second lien would not work on that property.
Other breaking points deserve attention:
- Valuation. The program is not sized on the price you paid or the number you hope for. It is sized on the lender’s valuation. A lower number cuts into the leverage room dollar for dollar at the ceiling.
- Later refinancing. A future lender will see both liens. A cash-out refinance down the road would have to pay off the first mortgage and the line.
- Product labels. Any product that pays off your first mortgage works like a cash-out refinance, whatever it is called. It is a different structure and a different file.
- Lender discretion. HELOC lenders can reduce or freeze a line if the property’s value falls, per the CFPB’s HELOC booklet. Do not count on a line staying available for a future need if the market turns.
- Two properties are not one. The line attaches to the one property pledged. CLTV is measured on that property alone, however many other rentals you own, within the exposure limit above.
Line or Cash-Out Refinance: What the Decision Looks Like
Start with why you want the cash. Typical uses are a down payment on the next rental or a rehab on this one. Because it is business-purpose financing, the funds are meant for investment use, not personal spending. Tax treatment varies; consult a qualified professional before relying on any deduction.
Keeping your first mortgage is the main reason to choose a second lien. If you like the existing loan, there is no reason to disturb it. A line leaves the first mortgage untouched and adds a second payment behind it.
That second payment is the cost. It is tested on the full limit at a stressed payment, so it can sink a rental that passes alone. Check your coverage with the line sized before you apply.
Now size the cash. Your window on this property is narrow, a little over twice the minimum line before any haircut. If that covers the down payment or the rehab, the line is the clean fit. If you need materially more, a cash-out refinance may serve you better. It resets the first mortgage and opens a different leverage grid, but it also changes the loan you already have.
A quick sensitivity check shows what moves the file:
| Change | CLTV effect | Coverage effect |
|---|---|---|
| Higher valuation | More room | None directly |
| Lower valuation | Less room | None directly |
| Larger line | Higher CLTV | Larger stress payment |
| Lower rent (lease or 1007) | None | Coverage falls |
| Declining-market flag | Ceiling cut 5 points | None directly |
Per the CFPB’s overview of home equity lines, equity is value minus what you owe, and a HELOC runs as a draw period followed by repayment. That general framework holds here, though this program’s own terms are the ones listed above.
Key Terms Defined
DSCR (debt service coverage ratio): monthly rent divided by the payment the lender tests, with 1.10x as the minimum on this program.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
Second lien: a loan secured by the same property that sits behind the first mortgage in repayment priority.
Stress payment: the fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points, used only to test coverage.
Draw period: the 5-year stretch when you borrow against the line and pay interest only on the drawn balance.
Repayment period: the 25-year stretch after the draw period when the balance is fully amortized.
Form 1007: the appraiser’s market-rent schedule, which sets the rent the lender may use if your lease is higher.
Frequently Asked Questions
Can I get a DSCR HELOC without refinancing my $500K first mortgage?
Yes, through select programs, the line is a standalone second lien behind the first mortgage you keep. The first mortgage stays untouched. The new line must clear both the 70% CLTV ceiling and the 1.10x coverage test, subject to underwriting. On this property the leverage test usually limits the line size first.
How much room does the $860K value leave under a 70% CLTV cap?
About 12 points of value above your current 58.1% leverage. That window is a little more than twice the $50,000 minimum line. A lower valuation or a declining-market flag cuts the room, and in a location with a 10-point lower ceiling there would be none. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Does my own income matter for this line?
No. The line qualifies primarily on property-level rental income covering the stress payment, subject to lender guidelines. Your tax returns, W-2s and debt-to-income ratio are not part of the calculation. Credit, the lease, the valuation and the property are still reviewed.
Can my LLC hold title on the rental?
Yes, subject to program terms, vesting in the owner’s LLC is allowed on investment property. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
What if my credit score is under 720?
Then this second-lien program is not available, because 720 is the minimum on a second lien. A first lien on a rental with no mortgage starts at 700. Your options at a lower score depend on the property, the program and current lender guidelines.
