The Quick Read: A DSCR HELOC is a revolving line of credit placed on a rental you already own, and it is reviewed on that rental’s income rather than yours. You use the cash it produces to buy your next rental, which is financed separately and judged on its own rent. Everything below is subject to underwriting and lender guidelines.
- The line is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage.
- The rent is tested against a stress payment on the entire credit limit, with a minimum coverage of 1.10x.
- A second-lien line tops out at 70% combined loan-to-value, at a 720 credit score or better.
- At least 80% of the line is drawn at closing, so it works more like a funded loan than a standby reserve.
- The line sits on the property you own today. It cannot be closed with the purchase of the next one. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
What Does “Second Investment Property” Mean Here?
The phrase “second investment property” trips up many first-time readers. The line does not go on the property you are buying. It goes on the rental you already hold, and the cash it produces becomes the down payment on the next one.
Two separate loans do the work. The line on rental A produces cash. A purchase loan on rental B buys the property. Each loan is judged on the collateral behind it.
This is why timing matters. The line has to exist before you go under contract on rental B. It also helps to know where the line sits compared with the alternatives. Here is the side-by-side:
| Factor | DSCR HELOC | Cash-out refinance | Bank-style investment HELOC |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Stays in place |
| Main test | Rent vs. stress payment | Rent vs. new payment | Your credit and debt-to-income |
| Structure | Revolving line | Closed-end loan | Revolving line |
The last column describes a different product that happens to share part of the name. The next sections cover why that matters.
How Does Underwriting Treat the Line, Step by Step?
Underwriting runs on the property. You do not submit tax returns, W-2s or pay stubs, and the lender does not calculate a personal debt-to-income ratio. The rent, the lease, your credit report and the valuation are all documented.
Across Lendmire’s wholesale network, the review follows the same order on most files.
1. Eligibility screen. The property type, the borrower type and the seasoning get checked first. Citizens, permanent residents and non-permanent residents with a Social Security number qualify. Foreign nationals and ITIN borrowers do not qualify for this program.
2. Rent. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The market rent comes from the appraiser’s rent schedule, Form 1007. A lease in place is required. A two-to-four-unit property may have at most one vacant unit.
3. Coverage test. Gross monthly rent is divided by the qualifying payment. That payment is a fully amortizing principal-and-interest payment on the entire credit limit at the start rate plus 2 percentage points. Taxes and insurance are not part of it. The minimum coverage is 1.10x.
4. Leverage test. The first mortgage balance plus the new line, divided by value, cannot pass the ceiling for your credit tier.
5. Credit and history. The credit tier comes from the lender’s own report. No 30-day mortgage late is allowed in the last 12 months. Bankruptcy, foreclosure, short sale or deed-in-lieu must be at least 48 months old.
6. Valuation and title. Covered below.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. The lender’s own calculation governs, and every number here is illustrative.
Why Does the Stress Payment Use the Whole Line?
The test is run on the full credit limit, not on the amount you draw. This is the most common surprise for new investors. You could draw only part of the line and the test would not change.
Run the numbers this way. Say your rental carries a first mortgage you like, and you ask for a large line. If rent covers the stress payment about 1.25 times, the file clears the 1.10x minimum. If rent covers it only about 1.05 times, the file falls short. Sizing the line smaller shrinks the stress payment and lifts the ratio. The fix is a smaller limit, not a smaller draw.
DSCR loans use gross rent divided by a payment. Commercial lenders use net operating income divided by annual debt service. Same name, different formula. Do not carry the commercial range into this product.
How Much Can You Borrow Against the Rental?
Leverage depends on the lien position and your credit score.
On a second lien behind your existing first mortgage, combined loan-to-value (CLTV) can reach 70% at a 720 credit score or better, on lines from $50,000 up to $500,000. CLTV means the first mortgage balance plus the new line, divided by property value. Below a 720 score, there is no second-lien tier. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
On a first lien for a rental with no mortgage, the figures are loan-to-value (LTV):
- 740 or better: up to 75% LTV on lines up to $500,000.
- 700 to 739: up to 70% LTV on lines up to $500,000.
- Lines above $500,000, up to $1,000,000: 65% LTV at 720 or better. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
A borrower who keeps a first mortgage can only take a second lien. A first lien exists only on a rental with no mortgage. A declining-market flag lowers the ceiling 5 points, and Philadelphia lines carry a ceiling 10 points lower. All of this runs through select programs and is subject to underwriting.
The program asks for no reserves and no cash to close on the line. Exposure is capped at 5 loans or $2,500,000 per borrower with the program.
How Does the Line Behave After Closing?
The line has a 5-year interest-only draw period on the drawn balance. A 25-year fully amortizing repayment period follows, with a 30-year maturity. The rate is variable. The rate and the pricing terms come with the lender’s disclosures.
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.
The CFPB explains that a variable rate lets payments change over time, and that payments are often significantly higher once repayment begins. The FTC adds that you pay interest only on what you borrow, and many lines are interest-only during the draw period. Both agencies write for owner-occupied homes. The mechanics carry over to a rental line, but the consumer framing is aimed at a different product.
For your plan, this means the payment steps up when the interest-only years end. A mostly drawn line also starts costing interest from the first day. Do not open a line you will not use.
How Does the Line Fund Your Next Rental?
The sequence for a growing portfolio looks like this.
1. Own rental A for long enough to meet the seasoning rule.
2. Open the line on rental A.
3. Use the cash as the down payment on rental B.
4. Qualify the purchase loan on rental B using rental B’s own rent.
5. Later, pay the line down or refinance into permanent financing.
The line’s payment belongs to rental A. Rental B is tested on its own coverage, so the line does not drag B’s ratio down. The purchase lender will still see the new line while reviewing your credit and your source of funds. Borrowed money is a disclosed source. Confirm how the purchase lender treats it, and confirm that lender’s own reserve rules.
Here is how the sequence stacks as the portfolio grows:
| Step | Property | What happens |
|---|---|---|
| 1 | Rental A | Line opened against equity |
| 2 | Rental B | Purchased with line proceeds as down payment |
| 3 | Rental B | Purchase loan tested on B’s rent |
| 4 | Rental C | Next line opened on A or B, once each meets seasoning |
Each line counts toward the exposure cap of 5 loans or $2,500,000 per borrower with the program. Plan the sequence around that ceiling.
What Is the Seasoning Rule?
The rule has two six-month clocks. 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).
This is why a brand-new purchase usually cannot fund the next one immediately. Count backward from your last purchase or refinance before you plan the next move.
Which Properties and Borrowers Are Eligible?
Eligible properties include single-family homes, PUDs, townhomes, two-to-four-unit properties, and warrantable and non-warrantable condominiums. Lots up to 10 acres also qualify. The leverage tiers above govern every property type.
These are not eligible on this lane:
- 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 property
- A property listed for sale in the prior 2 months
- A property with a solar lien
Vesting in your LLC is allowed 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. The borrowers on the line need not be the borrowers on the first mortgage.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is the broker. A wholesale lender in its network places and underwrites the line.
What Valuation Does the File Need?
Lines up to $400,000 use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal (Form 1004, 1073 or 1025). Appraisal waivers are not accepted.
Title follows the loan size. A full title policy is required on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report. Hazard insurance covers both liens, with flood coverage where required.
Gather these before you apply:
- Lease and rent history
- First-mortgage statement
- Insurance
- Entity documents, if the LLC holds title
- Credit report authorization
- Title and valuation orders
Where Does the General Rule Break?
Several edge cases catch investors who read only the headline.
Two products share the name. NerdWallet notes that a HELOC on an investment property is harder to get than one on a primary home, and not every lender offers one. It also points to a DSCR second mortgage as an option for a mostly rented property. That bank-style product is judged on your personal credit and debt-to-income. A rent-qualified DSCR line is judged on the property. Some products sold as lines are really closed-end seconds that pay a lump sum. Ask whether the product is truly revolving.
It is not a standby reserve. With at least 80% drawn at closing, the line behaves like a loan with a small undrawn remainder. It is a poor fit if you want a large untouched cushion.
The line cannot buy the property directly. It supplies cash only. The purchase loan is written separately.
A line is never a third lien or a line on your home. It also cannot sit on an owner-occupied home or a second home.
Rent drops hurt twice. A variable rate and a falling lease can push coverage toward 1.0 while the loan stays the same size.
Line, Cash-Out Refinance or Neither?
Choose by looking at the first mortgage. If your existing first mortgage is worth keeping, the line leaves it untouched. If you are refinancing anyway, or the first mortgage has weak terms, a DSCR cash-out refinance replaces it and may fit better.
A few rules of thumb from broker practice:
- Pick the line when the first mortgage is worth keeping and you need cash from a single rental.
- Pick the cash-out refinance when the first mortgage is a weak one or you need a larger amount.
- Do not use either without an exit plan, such as paying the line down or refinancing after the next property stabilizes.
The funds you draw are a business-purpose use. 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 complete DSCR loans guide covers the broader program family if you are comparing several structures.
Key Terms Defined
DSCR: Debt service coverage ratio. Here, gross monthly rent divided by the qualifying payment.
CLTV: Combined loan-to-value. The first mortgage balance plus the new line, divided by property value.
Lien position: Where a loan stands in line for repayment if the property is sold. A second lien sits behind the first mortgage.
Draw period: The stretch in which you can take money from the line. On this program it is 5 years and interest-only on the drawn balance.
Stress payment: The payment the lender tests on the full credit limit at the start rate plus 2 percentage points.
Seasoning: The waiting period a lender requires after a purchase or refinance before the property can carry a new loan.
Frequently Asked Questions
Can I use a DSCR HELOC on more than one property?
Yes, one line per property, within the program’s exposure cap of 5 loans or $2,500,000 per borrower. Each rental is tested on its own rent, credit tier and leverage. The cap counts every loan with the program, so plan the sequence before you start.
How soon after buying a rental can I open a line?
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).
Does my personal income matter?
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 personal debt-to-income calculation. Your credit score, mortgage history and the property still get reviewed.
Does the line’s payment hurt the next property’s coverage ratio?
Not in the coverage math. The line’s payment is tied to rental A, and rental B’s purchase loan is tested on rental B’s own rent. The purchase lender will still see the new line in your credit and funds source.
Can my LLC hold title?
Yes on investment property, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs the non-borrowing owner acknowledgment and the security instrument.
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. Small first-time lines and portfolio sequences both start with the same question: does the rent clear the stress payment on the full limit?
