The Quick Read: Credit unions generally do not offer a DSCR-qualified line on a rental; they underwrite the borrower’s income and debt-to-income ratio, while a true DSCR line qualifies primarily on the property’s rent, subject to lender guidelines. Through select programs in Lendmire’s wholesale network, the line sits as a standalone second lien behind the first mortgage the owner keeps, or as a standalone first lien on a rental with no mortgage.
- Minimum coverage is 1.10x: gross monthly rent divided by a qualifying payment, which is a stress payment on the entire line. Taxes and insurance are not part of that payment.
- A second lien reaches 70% combined loan-to-value at a 720 score or better, on lines of $50,000 to $500,000.
- Terms: a 5-year interest-only draw period, a 25-year repayment period and a 30-year maturity, on a variable rate.
- No traditional personal-income documentation, W-2s or personal income calculation, and the LLC can stay on title, per lender program requirements.
- Offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
A credit union line on a second rental is tied to the borrower’s own file. The credit union wants the borrower’s pay stubs, tax returns and debt load. Each financed rental adds debt, so the line shrinks as the portfolio grows. This article explains why that happens, how the DSCR version differs, and where each route breaks. For the full product picture, see the complete DSCR loans guide.
Do Credit Unions Offer a DSCR HELOC?
Not as a published product. Credit unions that lend against rentals use consumer-style, full-documentation underwriting: credit, income, debt-to-income, and some portion of the rental income counted toward qualifying. The rent supports the borrower’s file. It does not carry it.
The regulatory history explains why rental lines were scarce for years. Before 2018, a credit union loan counted as a member business loan unless it was secured by a dwelling that was the member’s primary residence. NCUA’s legal opinion on the member business loan exception says Congress limited the exception to a dwelling that is the member’s primary residence. A rental line therefore counted against the credit union’s statutory business lending cap.
That changed when NCUA removed the occupancy requirement for loans on one-to-four unit dwellings. The exclusion from the business lending cap does not extend to a loan secured by more than one such property.
Two practical points follow. A credit union can write a line on one rental without cap pressure, but whether it does is a credit-policy decision. And a line cross-collateralized on several rentals loses the exclusion, so it counts against the cap again.
Nothing in those rules mentions DSCR. Property-rent-based lender review is an investor-lending convention, and it lives mostly in non-bank and non-QM channels.
What a Credit Union Underwrites on a Second Rental
The file is borrower-centric. Expect these items:
- Membership in the credit union before anything else.
- A second lien behind the existing first mortgage, capped on combined loan-to-value.
- Credit review, income documents and a debt-to-income test.
- Leases and rent documentation, with rental income counted at a discount.
- Valuation that can be heavier on a rental than on a primary home.
Credit union policies also change. Investor discussion on BiggerPockets describes one credit union that limited investors to a handful of properties and later stopped writing rental lines. Read that as a reminder that appetite moves, not as current policy anywhere.
The scaling problem is arithmetic. Each rental financed adds a payment to the borrower’s debt-to-income ratio. A W-2 or tax-return profile has finite room. Property-count caps and LLC exclusions are the other common walls, and a line that requires personal title can force the owner out of the entity.
How the DSCR Version Underwrites the Rental
A DSCR HELOC flips the test. The rent qualifies the line, and the owner’s income is never calculated. Across the wholesale network, these programs share a consistent structure.
Lien position. The line is a standalone second lien behind the first mortgage the owner keeps, or a standalone first lien on a rental with no mortgage. It is never closed together with a purchase, never a third lien, and never placed on the owner’s home or a second home.
The coverage test. Minimum DSCR is 1.10x. That is gross monthly rent divided by a qualifying payment, which is a fully amortizing payment on the entire credit limit at a stressed start rate. Taxes and insurance are not part of that qualifying payment. 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, and a two-to-four unit property may have at most one vacant unit. Confirm on the file how the lender treats the first-mortgage payment on a second lien, because the lender’s own coverage calculation governs. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Qualifying on the full line, not the drawn balance, matters. A large line with a small draw still has to pass at full size. Any worked numbers here are illustrative, and the lender’s calculation controls.
Title. The LLC can stay on title, 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. The borrowers on the line need not be the borrowers on the first mortgage.
Leverage Tiers
Leverage depends on lien position, and the two use different terms. Second liens are measured as combined loan-to-value (CLTV): the first mortgage balance plus the new line, divided by value. First liens are measured as loan-to-value (LTV).
| Position | Score | Maximum | Line size |
|---|---|---|---|
| Second lien | 720+ | 70% CLTV | $50,000 to $500,000 |
| First lien | 740+ | 75% LTV | Up to $500,000 |
| First lien | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien | 720+ | 65% LTV | Above $500,000 to $1,000,000 |
All figures are ceilings through select programs, subject to underwriting. A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
Below 720 there is no second-lien cell. A borrower who keeps a first mortgage can only take a second lien, and the second-lien floor is 720. A first lien exists only on a rental with no mortgage, and its lowest tier starts at a 700 score for lines up to $500,000, while lines above $500,000 need 720.
Draw Rules, Terms and the Variable Rate
The draw period is 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period begins, with a 30-year maturity. The rate is variable. The rate and the pricing terms come with the lender’s disclosures.
The draw mechanics catch investors who expect a revolving card. 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. A borrower who wants a large undrawn cushion is better served by a different structure, because the line begins mostly funded.
The File: Valuation, Credit, Seasoning and Exposure
Valuation. 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 is a full policy on a first lien and on second liens above $400,000, and an owner-and-encumbrance report on smaller second liens. Hazard insurance covers both liens, with flood coverage where required.
Credit. The minimum is 720 on a second lien and 700 on a first lien, based on the lender’s own report. Mortgage history shows no 30-day late in the last 12 months, and 48 months must pass since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required.
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).
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 are eligible. Foreign nationals and ITIN borrowers are not.
What Disqualifies a Rental
Eligible property includes single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums, plus lots up to 10 acres. Several property types fall outside this lane:
- Rural-designated property
- Row homes
- Condotels
- Commercial, agricultural or mixed-use property
- Leaseholds and land trusts
- Age-restricted communities and hobby farms
- Modular and log homes
- Land contracts
- A property listed for sale in the prior 2 months
- A property with a solar lien
Row homes and listing history are the two items that most often surprise owners who assumed a rental was eligible. Check both before spending money on a valuation.
“Second Investment Property” Has Two Meanings
An investor may mean a line on the second rental. Or the investor may mean using one property’s equity to buy the second. The DSCR HELOC fits the first reading directly. For the second, the order of events matters.
The line is never closed together with a purchase, so it must exist before the purchase, on a rental that already meets seasoning. Run the sequence like this:
1. Confirm the first rental clears the seasoning clocks and is not in an excluded category.
2. Test coverage at 1.10x on the stress payment across the full line size, not the planned draw.
3. Confirm the combined leverage fits the tier for the lien position and credit score.
4. Open the line, then use the draw toward the next acquisition.
5. Confirm with the purchase lender whether borrowed down-payment funds are acceptable, since that is the purchase lender’s rule.
Credit unions are generally more comfortable lending against the owner’s primary residence, and investors often fund rentals that way. That is a different, owner-occupied product, and the DSCR line is never offered on an owner-occupied home.
Comparing the Three Routes
| Factor | Credit union rental HELOC | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|---|
| Reviewed on | Borrower income and DTI | Property rent | Property rent |
| First mortgage | Stays in place | Stays in place | Replaced |
| LLC title | Often excluded | Allowed | Per program terms |
| Scaling limit | DTI and property count | Per-borrower exposure | Per-borrower exposure |
The credit union column describes typical consumer-style policy, which varies by institution. The strongest case for the DSCR line is an investor whose personal file has no room left but whose rental has equity and a fixed first mortgage worth keeping. A cash-out refinance fits better when the owner wants to replace the first mortgage anyway.
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.
Key Terms Defined
CLTV: Combined loan-to-value, the first mortgage balance plus the new line, divided by the property’s value.
Stress payment: The fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points, used only to test coverage.
Standalone second lien: A line recorded behind the first mortgage, closed on its own and never with a purchase.
Draw period: The 5 years when the drawn balance is interest-only before repayment begins.
Seasoning: The ownership and note-date clocks a rental must satisfy before it is eligible.
Where the Route Choice Lands
The decision reduces to one question: does the investor’s personal income file have room? If it does, a credit union line can be a reasonable, low-cost tool, within its policy on property count and entity title. If it does not, or if the rental sits in an LLC, a DSCR line qualifies the property instead. Lendmire is a mortgage broker, so it can compare DSCR HELOC options across wholesale lenders in its network, matching the property, the rent, the equity available, credit profile and combined leverage to the program.

Frequently Asked Questions
Do I need to be a credit union member to use a credit union for a rental line?
Yes. Membership eligibility is the first gate, and some credit unions restrict who can join. A DSCR line through a wholesale lender has no membership step, though it does require meeting program credit, property and seasoning rules.
Can an LLC hold title on a DSCR HELOC?
Yes, on investment property, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. Credit union lines are more often reported to require personal ownership.
How long must I own the rental before opening the 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).
Can I take a DSCR HELOC on a rental with no first mortgage?
Yes, as a standalone first lien, with a 700 credit score floor. Leverage runs up to 75% LTV at 740 or better on lines up to $500,000, and 65% LTV at 720 or better on larger lines up to $1,000,000. Everything is subject to underwriting. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Does the line need an appraisal?
A valuation is always required, and appraisal waivers are not accepted. Lines up to $400,000 can use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal.
