Can you get a HELOC on a second home or investment property?

A HELOC on a second home or investment property works the same mechanically as one on a primary residence: you borrow against the equity you've built, draw funds as needed during the draw period, and repay with variable-rate interest on the outstanding balance. The difference is underwriting stringency. Lenders treat non-primary properties as higher risk — owners are statistically more likely to default on a vacation home or rental property than on the house they live in. That elevated risk translates directly into tighter terms and fewer lenders willing to offer the product at all. The CFPB's home equity guide covers the fundamental HELOC structure; lender overlays for non-primary properties go beyond the federal minimum floor.

Second home vs. investment property: an important distinction

Lenders distinguish between a second home (a property you personally occupy for part of the year — a vacation cabin, a beach house) and an investment property (a rental you never personally occupy). Both face tighter HELOC requirements than a primary residence, but investment properties are treated as the highest risk category and face the strictest terms. Misrepresenting an investment property as a second home on a loan application is mortgage fraud — a federal offense under 18 U.S.C. § 1014.

How requirements differ from a primary-residence HELOC

• Combined loan-to-value (CLTV): Primary residences: up to 85% CLTV at many lenders. Second homes: typically 75–80% max. Investment properties: typically 70–75% max — you need meaningfully more equity.
• Minimum credit score: Many lenders require 680–700 for a second home HELOC and 700–720+ for an investment property HELOC, versus 620 for a primary residence.
• Debt-to-income ratio: Tighter caps, often 43% or below, and the rental income from the investment property may only be partially credited (typically 75%) in DTI calculations.
• Rate premium: Non-primary HELOCs typically carry rates 0.25–0.75% above comparable primary-residence lines.
• Lender availability: Many national banks and credit unions only offer HELOCs on primary residences. Portfolio lenders and regional banks are the more common source for second home and investment property lines.

Alternative ways to tap equity in a non-primary property

If a HELOC isn't available on your second home or investment property — or if you want to avoid the risk of a lien on the property — there are other paths. A cash-out refinance replaces the existing mortgage with a larger one and delivers the equity difference in cash; it locks in a fixed rate but resets the loan term. A home equity loan (lump-sum second mortgage) is sometimes more available on investment properties than a revolving HELOC. For investors, DSCR (debt-service coverage ratio) loans underwrite entirely on the rental property's cash flow with no personal income verification required. The CFPB's home equity tools page outlines the full range of home-equity products. Financing is only one piece of building a durable rental portfolio — ClearValue Books' best books for rental property investing covers the acquisition, screening, and management side.

Tax treatment of HELOC interest on non-primary properties

The deductibility of HELOC interest on non-primary properties depends on how the funds are used. Interest on debt used to buy, build, or substantially improve the property securing the loan may qualify as mortgage interest. Interest used for other purposes (paying off credit cards, personal expenses) is treated as personal interest and is not deductible. Consult a tax professional — the rules are use-based, not property-based. The IRS Publication 936 covers the home mortgage interest deduction in full.
