The Quick Read: It depends on your equity. A DSCR HELOC on a rental is sized at up to 70% combined loan-to-value on a second lien, or 75% loan-to-value on a paid-off rental at the top credit tier, with the lender’s dollar ceiling capping it either way. Buying notes with the money does not change that math. Whether a lender will allow note purchases is a separate use-of-proceeds question, so confirm it before you plan around it.
- A second lien (behind a first mortgage you keep) reaches 70% CLTV at a 720 credit score or better, on lines up to $500,000, subject to underwriting.
- A first lien (a rental with no mortgage) reaches 75% LTV at 740 or better, and 70% at 700 to 739, on lines up to $500,000.
- First-lien lines above $500,000 run to $1,000,000 but at 65% LTV.
- The rent has to cover a stress payment on the whole line, not just the part you draw.
- A line is not a note-buying product. It is rental-equity financing, and the notes are your own business decision. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
What a DSCR HELOC Actually Is
A DSCR HELOC is a revolving line of credit secured by a rental you keep. It qualifies primarily on the property’s rental income covering the payment, subject to lender guidelines. The owner’s tax returns, W-2s and personal income are not calculated.
It comes in two shapes. A standalone second lien sits behind the first mortgage you keep. A standalone first lien sits on a rental with no mortgage. It is never closed with a purchase, never a third lien, and never placed on your own home. Through select programs, the LLC can stay on title, subject to underwriting.
Key Terms Defined
DSCR (debt service coverage ratio): the rental’s gross monthly rent divided by the qualifying payment. This program wants at least 1.10x.
CLTV (combined loan-to-value): every loan secured by the property, plus the new line, divided by the property’s value. Investopedia’s definition matches how it is used here.
LTV (loan-to-value): the same idea with only one loan on the property.
Lien position: your place in line if the property is sold to pay debts. A first lien is paid before a second.
Draw period: the stretch when you can borrow from the line. Here it is 5 years, interest-only on the drawn balance.
Mortgage note: a loan someone else owes, secured by a property. You buy the right to the payments.
How the Maximum Is Calculated
The maximum is the smaller of three numbers: your equity room, the program’s dollar ceiling, and what the rent can support. Most borrowers hit the first one. High-value, low-debt properties hit the second. Large lines on thin rent hit the third.
Step 1: Equity room. Take the leverage cap times the property’s value. Subtract every lien already recorded. What remains is the most the line can be.
Step 2: Dollar ceiling. A second lien tops out at $500,000. A first lien runs to $1,000,000, but the percentage drops on larger lines.
Step 3: Rent test. The qualifying payment is a fully amortizing principal-and-interest payment on the entire credit limit at a stressed rate. Taxes and insurance are not part of it. Rent divided by that payment must reach 1.10x.
Take the smallest of the three. That is the line.
The leverage tiers
| Lien type | Credit score | Max leverage | Max line |
|---|---|---|---|
| Second lien | 720+ | 70% CLTV | $500,000 |
| First lien | 740+ | 75% LTV | $500,000 |
| First lien | 700-739 | 70% LTV | $500,000 |
| First lien, larger lines | 720+ | 65% LTV | $1,000,000 |
These are ceilings, not offers, and they apply to non-owner-occupied rentals subject to underwriting. Below 720 there is no second-lien tier. A borrower at 700 to 719 who keeps a first mortgage has no second-lien cell on this program.
A declining-market flag can lower the ceiling by 5 points. Lines start at $50,000.
Rent: the part people trip on
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 must be in place. A two-to-four-unit property can have at most one vacant unit.
Because the stress payment covers the whole limit, a bigger line needs more rent even if you draw less later. And on a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. Lender guidelines govern, and any coverage math you run yourself is illustrative.
Sizing Examples in Percentages
Run the numbers on four rentals. These are modeled scenarios, not market data, and no dollar amounts are needed.
A rental with no mortgage, 740 score. The cap is 75% LTV, up to $500,000. On a modest property, equity room binds first. On a high-value one, the $500,000 ceiling binds first. Going above it means 65% LTV on a first-lien line. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
A rental with a first mortgage at 50% of value, 720 score. The second-lien cap is 70% CLTV. That leaves 20 points of value as the most the line can be. Subtract the first mortgage from the cap, nothing more.
A rental with a first mortgage already at 70% of value. There is no room. Nothing to borrow.
A rental with a first mortgage, 705 score. The second-lien tier needs 720. Raising the score is the fix, or a different structure altogether.
Notice what none of these depend on: what you plan to buy with the money.
Can You Borrow on a DSCR HELOC for Investing in Mortgage Notes?
Possibly, but nobody should promise it. The line’s limits stay the same whatever the proceeds buy. Whether a given lender permits note purchases is a use-of-proceeds and underwriting question. Confirm it against the specific program’s guidelines before you assume it.
Start from what the product is: financing against rental equity. The valuation, the rent test and the lien all attach to the rental. The notes are a separate investment you carry on top.
Here is how the money behaves once you have it.
Most of the line is drawn on day one. At least 80% of the line is drawn at closing. On the smallest lines, that means the whole line. Interest runs on that drawn balance from the start, while you hunt for notes. Later draws must be at least $5,000 each.
The rate is variable. Notes usually pay a fixed coupon. A floating cost against a fixed return can squeeze the spread over time. A BiggerPockets discussion on funding note purchases with a HELOC raises exactly this mismatch.
The payment steps up. The draw period is 5 years interest-only. Then a 25-year fully amortizing repayment period begins, with a 30-year maturity. Notes can be illiquid, so plan for the day the payment changes.
Your rental must carry the line regardless. The rent qualifies the line, but a note that stops paying does not reduce what you owe. You carry three risks at once: the variable cost, a borrower defaulting on the note, and the cost of servicing or foreclosing. Honestly, this is a spread bet financed with rental equity. Size it like one.
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. IRS Publication 550 explains how borrowed money is treated by use.
What the File Looks Like
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. Appraisal waivers are not accepted.
Credit. The minimum is 720 on a second lien and 700 on a first lien, using the lender’s own report. No mortgage lates of 30 days in the last 12 months. Waiting periods run 48 months after 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).
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. Single-family, PUD, townhome, two-to-four units and condominiums are eligible, with lots to 10 acres. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, mixed-use and properties listed for sale in the prior 2 months are outside it. So is a property with a solar lien.
Where it is offered. The program runs in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is the broker. The line is placed through a wholesale lender in its network, and every file is underwritten individually.
Line vs. Other Ways to Fund Notes
| Option | Rent-based? | Structure | Fits when |
|---|---|---|---|
| DSCR HELOC | Yes | Revolving, variable | You keep the first mortgage |
| Cash-out refinance | Yes | One lump sum | You want to replace the first loan |
| Investment HELOC on personal income | No | Revolving | Your personal income file is strong |
| Cash | n/a | None | You can afford to tie it up |
Different lenders define these programs differently.
NerdWallet notes that the pool of lenders offering lines on investment property is smaller and the requirements stricter than on a primary home. That fits what the brokerage sees across lender guidelines.
Who Should Skip This
- You have no cushion if the rent drops or a tenant leaves.
- You are counting on the note spread to cover the variable cost.
- Your rental already sits near the combined cap.
- You need a first-lien line above $500,000 and cannot live with 65% LTV.
- You cannot hold the notes through a default or foreclosure.
- The only way to close the plan is one rosy yield assumption. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Frequently Asked Questions
What is the most I can borrow on a rental?
On a second lien, up to $500,000, and only if 70% of the property’s value minus your first mortgage leaves that much room. On a paid-off rental, a first-lien line runs to $1,000,000, with lines above $500,000 at 65% LTV. All of it is subject to underwriting and the rent test. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Does a higher credit score raise my leverage?
Partly. On a second lien, 720 is the entry point and 70% CLTV is the ceiling. On a first lien, 740 or better reaches 75% LTV while 700 to 739 stops at 70%. Score decides which tier you land in, not an open-ended increase. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Can the LLC hold title?
Yes, on investment property, subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Do I have to draw the full line?
At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. Plan for interest on most of the line from the start.
Will a lender let me spend the money on notes?
That depends on the lender’s use-of-proceeds terms and the specific program, so ask before you apply. The line is sized on the rental regardless of what the money buys.
