You can deduct the interest from your mortgage payments when you file a tax return, but only if the loan is secured by your home. Also, the loan proceeds must have been used to buy, build, or improve your main home and one other home you own and use for personal purposes.
Since most individual landlords have interest-only mortgages, you could basically claim all mortgage repayments. That's because you pay only the interest each month and the price of the property at the end of the period.
No, mortgage interest isn't always 100% deductible; it's subject to limits and conditions, primarily that the loan must be for buying, building, or improving your main or second home, and you must itemize deductions, with current limits at $750,000 of debt ($375k if married filing separately) for loans after December 15, 2017, while older loans have a $1 million limit, and you can only deduct the interest portion, not principal.
Many business expenses are 100% deductible, including advertising, employee wages, rent, supplies, and certain business meals like company parties or meals for the public, while personal deductions like student loan interest or charitable donations (depending on the type) can also be fully deductible for individuals. The key is that the expense must be "ordinary and necessary" for your trade or business or meet specific IRS criteria, often differentiating from the 50% rule for client meals.
Homeowners may refinance mortgage debts existing on 12/15/2017 up to $1 million and still deduct the interest, so long as the new loan does not exceed the amount of the mortgage being refinanced. The Act repealed the deduction for interest paid on home equity debt through 12/31/2025.
The mortgage interest deduction (MID) is worth it only if your total itemized deductions (including mortgage interest, property taxes, and charitable giving) exceed the much higher standard deduction, which is rare for many due to tax law changes. It reduces taxable income, saving money for those who itemize, especially those with large mortgages and high interest rates early in their loan, but it requires extra paperwork (Form 1098) and effort.
An interest only mortgage, a type of mortgage where you pay just the loan's interest. Once you reach the end of the mortgage term, you're required to repay the original mortgage amount (capital) in full.

A recent tax law, the "One Big Beautiful Bill Act" (OBBBA) from mid-2025, solidified the mortgage interest deduction (MID) by making the $750,000 debt limit permanent and added new provisions, like treating Private Mortgage Insurance (PMI) as deductible interest for some, starting in 2026, though income phase-outs apply for the PMI deduction. This bill provides clarity by confirming the $750,000 cap for most new loans and reinstating PMI deductibility for lower-to-moderate-income borrowers, easing some homeowner tax burdens.

“If you invest the money you would've used to pay off your mortgage into a retirement account, your return over the long term may exceed the savings of paying down your mortgage,” Poorman says.
