The Quick Read: Call or visit the credit union and request a line of credit secured by a one-to-four unit, non-owner-occupied property, then ask which desk handles it, how it treats entity-held title, what combined loan-to-value cap applies, and whether the line is first or second lien.
- Not every credit union offers this product, so the first call is a screening call.
- Underwriting leans on your personal income, debts, and credit more than on the rent.
- The line is sized by combined loan-to-value, so your existing mortgage balance counts against it.
- Terms are set by each credit union’s own policy, so two credit unions can answer very differently.
- A DSCR cash-out refinance is the usual fallback. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
What Is an Investment Property Line of Credit?
It is a revolving credit line secured by a rental property you own. You borrow what you need, repay it, and borrow again, and interest accrues only on the amount drawn. It works like a home equity line, except the collateral is a rental instead of the home you live in.

Most lines run in two phases. During the draw period you borrow and typically make interest-only payments. Then the repayment period begins, and you pay down principal. The rate is usually variable, so payments can move up or down. NerdWallet describes a 10-year draw followed by up to 20 years of repayment as a common shape for investment lines.
Wording matters. A HELOC is literally a home equity line. Some lenders decline a “HELOC for an investment property” but will write the same product under another name. So ask for a line of credit secured by an investment property.
Does a Credit Union Offer One?
Some do, and many do not. Credit unions are a sensible first stop because many keep loans on their own books. A lender that holds its own loans can write its own rules.
Market surveys report credit scores around 720 and up and combined loan-to-value caps near 80% on investment lines, with many lenders sitting lower. The same NerdWallet page is the source. Those are market-wide figures, not network figures. On a DSCR purchase of an investment property, the wholesale network Lendmire places files with typically lands at 75%-80% loan-to-value, and most programs want a score around 660.
You also have to be a member. Joining is standard practice, and you can usually ask about membership on the same call. Ask about it first, before you spend time on paperwork.
How to Ask, Step by Step
1. Check membership. Confirm you are, or can become, a member. Ask whether you must join before you apply.
2. Pick the right desk. Ask whether non-owner-occupied lines go through the consumer desk, the mortgage desk, or business lending. Credit unions route these differently.
3. Use the right words. Request a line of credit secured by a one-to-four unit, non-owner-occupied property. Skip the word HELOC.
4. State the lien position you want. Say whether you are asking for a first or second lien. Some lenders insist on first lien. That means owning the property free and clear, or folding the existing loan into the line.
5. Ask the screening questions. Cover the cap on combined loan-to-value, minimum credit score, limits on the number of financed properties, and whether the property’s state and type are eligible.
6. Ask about title. Say plainly if the property sits in an LLC, and ask what the credit union requires.
7. Ask about costs and terms. Cover appraisal, origination, annual, and early-closure fees. Ask about the draw length, the index and margin, and the renewal schedule.
8. Apply only after a yes. Run a full application once the screening answers fit your plan.
What to Bring
Bring more than you think you need. A typical package includes:
- The application and permission for a credit pull
- Proof of your income and a list of your debts
- A schedule of every property you own and the mortgage on each
- The current lease and rent history on the property
- Proof of insurance and clean title
- A personal financial statement and traditional personal-income documentation if asked
- Entity documents and a personal guarantee if an LLC is involved
Expect the credit union to order a valuation, such as an appraisal or an alternative. They are measuring equity, and the valuation sets that number.
How Underwriting Treats the Request
Underwriting is mostly personal. The credit union looks at your income, your debts, your credit, and your cash reserves. Stable rent helps, but lenders may credit only part of it. An existing tenant and documented rental history are generally expected.
The key test is combined loan-to-value, the total of all loans against the property divided by its value. Your existing mortgage counts against the line. Here is a modeled example, not a program or a quote. Assume a credit union caps combined borrowing at 70% of value. Assume your current mortgage equals 50% of value. The most the line could reach is the 20% of value left between the two.
That also shows why a paid-down property works better. More equity leaves more room under the cap. Reserves matter too. Credit unions often want to see cash left after you draw.
Why Terms Differ From One Credit Union to the Next
No federal formula sets investor-line terms. The National Credit Union Administration rewrote its member business lending rule to be principles-based rather than prescriptive. Each credit union now writes its own policies and limits.
The federal definition of a member business loan covers loans whose proceeds fund a business investment property. That is why your request may land on the business-lending desk. Federally insured state-chartered credit unions can follow an approved state rule instead, so appetite and paperwork can differ by charter.
Capacity is a factor as well. Business lending has a statutory cap tied to a credit union’s size. America’s Credit Unions notes that one-to-four unit non-owner-occupied loans have been reclassified so they do not count against it. That eases the pressure on small-landlord lines, but each credit union still decides how much of this it wants.
Where the General Rule Breaks
LLC ownership. Many lenders won’t write a consumer-style line to an LLC. Credit unions that do often want the entity’s documents, your personal financials, and a personal guarantee. Some investors retitle the property into their own name first. That move can raise due-on-sale, insurance, and liability questions, so talk to an attorney before you do it.
Property-count limits. Some credit unions cap how many financed rentals you can have. If you own several, ask about this before anything else.
Geography and property type. Some credit unions lend only on property inside their footprint. Many exclude co-ops. Ask whether your property’s state and type are eligible.
Renewal and freeze risk. Some lines come up for renewal on a set schedule. A lender may reappraise, run a new credit check, reduce the limit, or close the line. Treat the line as a tool that can change, not a permanent reserve.
Personal debt-to-income. A balance on the line can count against your ratios when you apply for the next loan. Heavy use can crowd out your next purchase.
Tax treatment. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Credit Union Line vs. DSCR Cash-Out Refinance
The two products answer different questions. A credit union line asks whether you can carry the debt personally. A DSCR loan asks whether the property’s rent covers its own payment. The complete DSCR loans guide walks through the second test.
| Factor | Credit Union Line | DSCR Cash-Out Refinance |
|---|---|---|
| Underwriting basis | Personal income and debts | Property rent vs. payment |
| Structure | Revolving, usually variable | Closed-end term loan |
| Property count | Often capped | Reviewed per file |
| Entity title | Often restricted | Subject to lender program eligibility |
| Availability | Limited, varies widely | Through network lenders |
Across the network, cash-out on a standard rental tops out around 75% loan-to-value. About 6 months of seasoning is the common expectation. Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Credit floors begin at 620 in parts of the network, most programs want around 660, and 700 and up opens the strongest tiers.
Reserves vary by lender, leverage, and loan size. About 6 months of PITIA is common, rising to about 9 months above $1,500,000. Standard programs go up to $3,000,000. The 30-year fixed is the spine, and select lenders add 40-year terms and interest-only periods.
One caution applies to both products. Clearing 1.00 does not mean positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, and capex sit outside that math. Manufactured homes, log homes, and barndominiums are not offered in these programs.
If you want a line of credit from the network side, Lendmire’s explainer Investment Property Equity Line Of Credit covers how that works. Network investment-property HELOC lines cap at $500,000 total.
If the Credit Union Says No
Start by asking why. A denial on property count, entity title, or debt ratio points you to a different product. A denial on credit or equity means the file needs work first.
You have three practical paths. Try a second credit union, since policies differ widely. Ask whether a first-lien refinance fits better. Or move to a DSCR cash-out refinance, which looks at the property’s rent against its payment instead of your personal debt ratio. Entity-held title is workable in many DSCR programs, subject to lender program eligibility. Investors with several properties often hit credit union limits, and DSCR is built for that situation.
For a closer comparison of the options, see Lendmire’s piece on HELOCs for investors who want a line of credit.

Frequently Asked Questions
Should I use the word HELOC when I ask?
Ask for a line of credit secured by an investment property. Some lenders decline a HELOC for an investment property but write a differently named product on the same collateral. Naming the collateral and the occupancy up front avoids a reflexive no.
Does the rent count toward qualifying?
Usually only in part. Credit union underwriting leans on your personal income and debts, and lenders may credit only a portion of projected rent. A signed lease and documented rental history strengthen the file.
Can I use my own home’s equity instead?
You can, and that is a different product with different risk. Your home becomes the collateral, so a default puts your residence at stake. Many investors prefer to keep the rental’s debt tied to the rental.
Is a credit union line easier to get than a bank line?
Not necessarily. Credit unions that keep loans on their own books can be flexible, but each sets its own limits on property count, title, and geography. Availability is the bigger hurdle than difficulty.
What if I hold the property in an LLC?
Ask before you apply. Some credit unions lend only to individuals, and some require a personal guarantee. If the answer is no, a DSCR loan is often the better fit, subject to lender program eligibility.
