HELOC for Investment Property: How the Interest Deduction Actually Works (2026)
The most common mistake landlords make with HELOCs isn't about whether to get one. It's about how the tax treatment works. HELOC interest used for a rental property is deductible, but not as home mortgage interest on Schedule A. It flows through as rental/business interest on Schedule E, following the IRS interest tracing rules (Temporary Treasury Regulation 1.163-8T). This is a more favourable treatment than many landlords realise, and it hasn't changed in decades.
This page covers: how the interest tracing rules actually work, how they interact with TCJA's home mortgage interest restrictions, what the 2025 One Big Beautiful Bill Act did and didn't change, whether to HELOC on your primary or the rental itself, and which lenders actually offer investment-property HELOCs.

Quick answer
- • HELOC interest for rental property = deductible on Schedule E, not Schedule A
- • Works whether the HELOC is on your primary residence or the rental itself
- • Rate premium for investment-property HELOC: 1–2.5 percentage points over owner-occupied
- • Fewer lenders offer investment-property HELOCs (Figure, TD Bank, select credit unions)
- • Keep meticulous records: the tracing rules depend on how proceeds are used, not how the loan is labelled
The Interest Tracing Rules: Why This Works
Under Temporary Treasury Regulation 1.163-8T, interest on a loan is categorised based on how the loan proceeds are used, not what property secures the loan. This is called the "interest tracing" rule.
For a HELOC, this means:
- Proceeds used to pay for a home improvement on the residence securing the loan → interest is qualified residence interest, deductible on Schedule A (subject to TCJA's mortgage interest caps).
- Proceeds used to buy or improve a rental property → interest is rental interest, deductible on Schedule E against rental income, with no TCJA-related cap on amount.
- Proceeds used for a business → interest is business interest, deductible on Schedule C or K-1 (subject to §163(j) for very large businesses).
- Proceeds used for personal expenses (car, vacation, wedding) → interest is personal interest, generally not deductible at all.
- Proceeds used for investments (stocks, bonds) → interest is investment interest, deductible on Schedule A Line 14, limited to net investment income.
TCJA (2017) restricted Schedule A home mortgage interest deductibility to debt used to "buy, build, or substantially improve" the qualified residence. This restriction applies only to the Schedule A path. It does NOT affect the Schedule E path for rental-property use, because the Schedule E path uses the tracing rules directly, not the home mortgage interest category.
Record-keeping is everything
The tracing rules are only as good as your documentation. If you draw $50,000 on a HELOC and the money sits in a mixed-use bank account for three months before being used for rental property, the IRS can require allocation based on where the money actually went. Best practice: fund a dedicated account for rental expenses from HELOC draws, and keep statements + invoices showing the trail from draw to property.
What the One Big Beautiful Bill Act Did (and Didn't) Change
OBBBA (Public Law 119-21, signed 2025) made two relevant changes for real estate investors. It did not change the interest tracing rules or broaden HELOC interest deductibility (despite claims you may see elsewhere).
What OBBBA changed
- 100% bonus depreciation restored permanently for qualifying business property (relevant for cost segregation on new rentals).
- §163(j) business interest limitation shifted from 30% of EBIT to 30% of EBITDA starting 2025 (more favourable for depreciation-heavy real estate businesses).
- The §163(j) limitation only applies to businesses with average annual gross receipts over $30M, so most individual landlords are well below this threshold and unaffected.
What OBBBA did NOT change
- Interest tracing rules (Temp. Reg. 1.163-8T), unchanged since pre-TCJA.
- TCJA restrictions on Schedule A home mortgage interest deductibility, still in place through at least 2025.
- Which property can secure the HELOC for rental-interest purposes. Tracing is proceeds-based, not collateral-based, and always has been.
Some blog posts and lender marketing materials claim OBBBA expanded rental-property interest deductibility. The IRS's own summary of OBBBA provisions does not contain any such change. Source: IRS: One Big Beautiful Bill provisions.
HELOC on Primary Home vs HELOC on the Rental Itself
The most common question from investors: which property should the HELOC be on? The honest answer is that almost everyone ends up choosing the primary residence for cost and speed reasons, accepting the risk concentration. Investment-property HELOCs exist but are materially more expensive and harder to get.
| Attribute | HELOC on Primary Residence | HELOC on the Rental Itself |
|---|---|---|
| Typical HELOC rate | ~7% variable | ~8–9.5% variable |
| Equity required | 15–20% (80–85% CLTV max) | 20–25% (75–80% CLTV max) |
| Credit score minimum | 620–680 common | 700+ common |
| Income reserves required | 2 months PITI typical | 6 months PITI per rental property owned |
| Lender availability | Most banks, credit unions, online lenders | Figure, TD Bank, some regional CUs (limited pool) |
| Documentation | Standard W-2 or self-employed docs | Plus Schedule E, leases, 1007 rental analysis |
| Interest deductibility (proceeds used for rental) | Schedule E (rental interest) | Schedule E (rental interest) |
The risk-concentration argument
A HELOC on your primary home funding a rental investment creates single-point-of-failure exposure. If the rental investment fails (extended vacancy, major repair, market decline) and you can't service the HELOC, you can lose your home. A HELOC on the rental isolates the downside to the rental property itself. Investors who are highly leveraged or in volatile rental markets sometimes accept the higher cost of an investment-property HELOC to isolate risk. Investors with strong primary-residence cash flow typically go the cheaper primary route.
Using a HELOC for the BRRRR Strategy
BRRRR (Buy, Rehab, Rent, Refinance, Repeat) is a common real estate investment strategy that relies on accessing capital quickly. HELOCs fit the strategy well because the draw period allows you to use capital in stages:
- Buy. Draw enough from the HELOC to cover the purchase price (or the down payment on a bank loan for the rental). Only pay interest on what you draw.
- Rehab. Draw additional funds phase-by-phase as the renovation proceeds. Interest accrues only on the draws, not the full line.
- Rent. Once the property is tenanted, rental income begins covering interest costs on the HELOC draw.
- Refinance. Once the rental has demonstrated cash flow (typically 6–12 months of leases), refinance it into a conventional investment-property mortgage. Pay off the HELOC balance with the refinance proceeds.
- Repeat. The HELOC is now undrawn and available for the next property.
The HELOC's flexibility (draw as needed, pay back and redraw) is specifically well-suited to BRRRR because you don't know exactly how much rehab will cost up front, and you want to recycle capital between properties without reapplying for financing each time.
BRRRR also works with a HELOC on the newly-acquired rental property if you used a cash purchase or a hard-money bridge loan. Once you've seasoned the property (6–12 months of ownership) and the rental is operating, you can open a HELOC on it and use that capital for the next acquisition. The tracing analysis follows the proceeds.
Lenders That Actually Offer Investment-Property HELOCs
The pool of lenders offering HELOCs on investment properties (as opposed to primary residences) is much smaller than most investors expect. Many mainstream banks that advertise HELOCs only offer them on owner-occupied homes. Lenders commonly cited as offering investment-property HELOCs include:
- Figure: online lender with a streamlined digital process. Offers HELOCs on investment properties including single-family rentals, condos, and some multi-family.
- TD Bank: one of the larger traditional banks that offers investment-property HELOCs in its footprint states.
- Regional credit unions: many local credit unions offer investment-property HELOCs at competitive rates for members. Examples include PenFed, Navy Federal, and various state-specific credit unions. Membership and state-availability restrictions apply.
- Portfolio lenders: some community banks and credit unions hold loans in portfolio rather than selling to Fannie Mae and Freddie Mac. These lenders have more flexibility on investment-property terms but often charge a higher rate.
