The Quick Read: An investment property HELOC is a home equity line secured by a rental you own. Credit union members can sometimes get one, but approval turns on the credit union’s appetite for non-owner-occupied collateral, your personal credit and debt load, and how much combined leverage the rental can carry. When the credit union says no, a rent-qualified DSCR cash-out refinance is the usual next step.
- Many credit unions reserve lines for primary homes, so the first call decides most files.
- On the network Lendmire places files with, an investment line tops out at 70% CLTV and $500,000.
- A HELOC is reviewed around personal credit and debt. A DSCR loan is reviewed for the property on its rent.
- Title matters: an LLC cannot hold title on these lines.
What Is an Investment Property HELOC?
A HELOC is a home equity line of credit, a revolving loan secured by the equity in a property. An investment property HELOC puts that lien on a rental instead of your own home.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Think of a free-and-clear duplex you rent out. You open a line against it and draw on the equity for repairs, a down payment, or the next purchase.
Lenders treat this differently from a line on your residence. The collateral is not where you live, so the lender sees more risk. NerdWallet’s investment HELOC explainer notes that some lenders restrict these lines by location or by whether the home is rented year-round. It also says multiple appraisals may be needed on a rental.
Lendmire is a broker. It arranges these lines through select wholesale partners and is never the lender. Every figure below is subject to lender guidelines and full file review.
How Underwriting Treats a Rental Line, Step by Step
The process runs in a fixed order. A file that fails an early step never reaches the later ones.
1. Membership and policy. You must be a member, and membership rules vary by credit union. The credit union must also write lines on non-owner-occupied property at all. Many do not.
2. Collateral and title. The lien goes on the rental. On the network’s investment line, title must sit with you personally or in a revocable living trust.
3. Sizing. The lender takes the property value, applies the maximum combined loan-to-value, then subtracts what you already owe. The next section works an example.
4. Personal qualification. This is not a rent test. The network’s investment line requires a 700 minimum credit score. Debt-to-income tops out at 50%, and the lender reviews your file on the interest-only payment at the maximum draw.
5. Valuation. Because an investment line caps at $500,000, it runs on automated valuation and commonly closes with no traditional appraisal. A borrower may still request a full appraisal. Credit unions set their own valuation policy.
6. Structure. The investment line runs a 5-year interest-only draw, then a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats through both periods and never converts to fixed.
That sixth step surprises people. A line on this network is not a dormant standby account.
Market surveys report that lenders often want a 720 score or higher and cap LTV at 80%, with many going lower, per NerdWallet. On the network, an investment line is 70% CLTV with a 700 floor.
Key Terms Defined
CLTV (combined loan-to-value): Every loan against the property added together, including the new line, divided by the property’s value.
Non-owner-occupied: A property you do not live in, which is how lenders classify a rental.
Draw period: The stretch when you can borrow from the line and pay interest only.
Repayment period: The stretch after the draw ends, when you pay principal and interest on a set schedule.
DSCR (debt service coverage ratio): Monthly rent divided by the full monthly obligation on the property.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly obligation used in the DSCR math.
Why Credit Unions Say No When the Rules Say Yes
The barrier is appetite, not law. Federal credit unions are not barred from lending against rentals. The federal member business loan rule, 12 CFR Part 723, excludes loans secured by a one-to-four family residential property from the commercial loan definition. That holds whether or not you live there. America’s Credit Unions, the trade association, lists the same exclusion.
So a credit union can write a rental line without building a commercial lending program. Many simply choose not to. Their home equity products were designed around members’ primary residences, and rentals fall outside that product box. Some credit unions will lend only in certain areas or only on certain property types.
If a credit union does offer rental lines, expect them to treat the file as personal-credit lending. Rent may support the file, but it does not carry it.
Sizing the Line: A Percentage Walkthrough
The formula is simple. Property value times maximum CLTV, minus existing liens, capped by the line limit.
Take a rental with an existing first mortgage equal to 45% of its value. On the network’s investment line at 70% CLTV, that leaves about 25 points of value available. A paid-off rental opens the full 70%. The $500,000 cap and the $25,000 minimum line then apply on top.
Higher credit does not buy more leverage here. Investment lines are a two-tier table: 720 and 700 both reach 70% CLTV. Credit above 700 buys eligibility, not leverage.
Your own home works differently. Primary-residence lines carry higher ceilings, but they put your home behind the rental. The table shows the tradeoff.
| Factor | Line on the rental | Line on your home |
|---|---|---|
| Leverage ceiling | Lower | Higher |
| Collateral at risk | The rental | Your residence |
| Lender appetite | Narrower | Wider |
| Valuation | Usually automated | Varies by size |
Title Decides Eligibility
Title is the quiet deal-killer. On the network’s HELOC program, only you personally or a revocable living trust can hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot.
| Title | HELOC outlook | Realistic route |
|---|---|---|
| Individual | Eligible | Standard line |
| Revocable trust | Eligible | Standard line |
| LLC | Not eligible | Vesting change or DSCR |
| Mixed portfolio | Property by property | Route each by title |
A rental already deeded to an LLC needs a vesting change or a DSCR cash-out instead. Moving title can have consequences with your existing lender, insurer, and liability planning, so think it through first. DSCR cash-out on LLC-held rentals is available subject to lender program eligibility. Lendmire’s piece Investment Property Line of Credit for an LLC-Owned Rental covers that side.
Where the General Rule Breaks
Several edge cases change the answer.
- A primary-home line to buy a rental. This is ordinary owner-occupied underwriting with the widest lender pool. It also puts your home behind the rental purchase.
- Funding 100% of a purchase with a line. You own the new property with no equity cushion. If values dip, you owe more than it is worth.
- Exposure limits. The network limits a borrower to three lines. A borrower owning more than 15 financed properties is not eligible.
- Property types. Single-family, 2-4 units, PUDs, townhomes, and condos (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural properties are not offered.
- Line changes after approval. Read the agreement for when the lender may reduce or freeze the line. A freeze matters most when you planned to draw later.
- Availability. Lendmire places these HELOCs in 16 full-service states, narrower than its 41-market DSCR footprint.
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.
Your First Call to the Credit Union
Skip the general pitch. Ask these specific questions:
1. Do you write lines secured by a non-owner-occupied one-to-four unit property?
2. What is the maximum combined LTV for that occupancy?
3. Do you accept individual or trust title, and do you lend against LLC-held property?
4. Is there a waiting period after a recent purchase or refinance?
5. What is the draw term, and does the line stay variable throughout?
6. How do you value the property, and can the line be frozen or reduced?
Lendmire’s piece How to Ask a Credit Union for an Investment Property Line of Credit goes deeper on the conversation.
When DSCR Is the Better Tool
If the credit union declines, or your title is an LLC, look at DSCR. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Our complete DSCR loans guide covers the basics.
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| Reviewed on | Personal credit, DTI | Rent vs PITIA |
| Leverage | 70% CLTV | About 75% LTV |
| Title | Individual or trust | LLC possible |
| Size | $25,000-$500,000 | Up to $3,000,000 on standard programs |
On a cash-out refinance, the network tops out around 75% LTV on standard rentals, with about 6 months of seasoning as the common expectation. Seasoning is the waiting period between buying and refinancing. Purchase files typically land at 75% to 80% LTV, and select programs reach 85% with roughly a 700+ score.
On coverage, 1.00 is where many select programs start, and stronger ratios open better leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. Most programs want around 660, and 700+ unlocks the strongest tiers. Reserves vary by lender, leverage, and loan size, and commonly run around 6 months of PITIA.
A DSCR above 1.00 is not positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
Structure options also differ from a HELOC. The spine is a 30-year fixed. Extended terms and interest-only periods are available through select lenders in the network, and ARM structures exist too.
How the Investor Decision Plays Out
Most files run in this order.
1. Ask your credit union the questions above. If the answer is yes, compare its terms with the network line. 2. If the rental is individually or trust-titled and you hold a 700 score, the network HELOC is worth pricing. 3. If the rental sits in an LLC, or your debt load is the obstacle, price a DSCR cash-out instead. 4. If you only need a down payment on the next purchase, compare a line on your primary home. Weigh that against the added risk to your residence.
The strongest files clear two tests: enough equity and enough rental coverage.
Frequently Asked Questions
Can I join a credit union just to borrow against a rental?
It depends on the credit union’s field of membership, which differs from one to the next. Some allow membership through an association or a small deposit. Before joining, confirm that the credit union writes lines on non-owner-occupied property at all.
Can an LLC-owned rental get a HELOC on this network?
No. Only individuals and revocable living trusts can hold title. A property already in an LLC needs a vesting change or a DSCR cash-out instead.
Does the rent count toward qualifying?
Rent can support the file, but a HELOC is reviewed around personal credit and debt-to-income, not on the property’s rent. DSCR loans work the other way, qualifying primarily on rental income covering the payment.
How large can an investment line be?
On this network, from $25,000 to $500,000, at 70% CLTV. There is no tier above $500,000 for investment property.
Does a paid-off rental get a bigger line?
It gets more room, because no existing lien reduces the CLTV available. The same cap and credit floor still apply.
