Rental property tax law is unusually generous to investors. Every April, landlords leave thousands of dollars on the table by missing deductions they are clearly entitled to. Here are the 12 most commonly overlooked.

This article is educational. Work with a CPA familiar with real estate for your specific situation.

1. Depreciation

The single largest deduction most landlords take. Residential real estate depreciates over 27.5 years (straight-line). On a $300K rental (excluding land value, roughly 80% of purchase price), you deduct roughly $8,700/year. Often wipes out most of your rental income on paper.

2. Mortgage Interest

100% deductible on loans secured by the rental. Includes origination points (amortized over loan life).

3. Property Taxes

Fully deductible, no cap (unlike the $10K SALT cap on personal returns).

4. Insurance

All property insurance, liability, umbrella (pro-rated for rental use), and even flood insurance premiums.

5. Repairs & Maintenance

Anything that returns the property to working order — roof patching, plumbing repair, painting, appliance repair. Deductible in the year incurred. Distinguished from improvements, which must be capitalized.

6. Management Fees

If you use a property manager, 100% deductible. If you self-manage, the time itself is not deductible, but related expenses are.

7. Travel to the Property

IRS standard mileage rate (67¢/mile for 2025) for trips to your rental for management purposes — inspections, showings, repairs, meeting tenants. Keep a mileage log.

8. Professional Services

9. Utilities You Pay

Any utilities you cover as landlord — common area electric, water, sewer, trash, lawn care. Fully deductible.

10. Advertising & Screening

Listing fees, photography, screening services, credit checks. All deductible.

11. Home Office (If You Qualify)

A dedicated home office space used exclusively for rental management qualifies for the home office deduction — either simplified ($5/sqft up to 300 sqft) or actual expense method. Requires exclusive and regular use.

12. Bonus Depreciation on Components

Appliances, flooring, HVAC components, and certain other items can be depreciated over 5–15 years instead of 27.5. Cost segregation studies break out components for accelerated depreciation — typically worth it on properties over $500K.

Short-Term Rentals Are Different

STRs (like Airbnbs) with average stays under 7 days and material participation can avoid passive loss limitations entirely — allowing losses to offset W-2 income. Discuss with a CPA; the rules are strict.

The Passive Loss Question

Rental losses are "passive" by default and can only offset other passive income. Exceptions:

Tracking Systems

Best-in-class investors track expenses monthly, not annually:

When to Hire a CPA

Once you own 2+ properties, a real estate CPA pays for themselves 5–10x. They catch deductions you would miss, structure entities tax-efficiently, and keep you out of trouble. Typical cost: $800–$2,500/year for a straightforward rental portfolio.

Real estate is one of the most tax-advantaged asset classes in America. Make sure you are taking full advantage.
