What Qualifies as Deductible Mortgage Interest? (The Answer Might Surprise You)

March 22, 2017

When it comes to being able to deduct the interest you pay on a mortgage, most people correctly assume that this applies to a home that you use as your primary residence. (There are some wonky rules around limits on the deductibility of certain types of mortgage interest from home equity loans or loans in excess of $1 million, which are best explained by Figure A on this page.) But many are surprised to learn that they may also be able to deduct interest paid on a second home and are even more surprised when they learn what the IRS considers a “qualified home.” Generally speaking, in order to be considered a home, a property must have sleeping, cooking and toilet facilities.

This means a boat, camper, or even a tricked out old ambulance could qualify as long as it has a bed, a stove and a toilet on board, and as long as any loan you took out to purchase the property is secured by the actual property. In other words, if you used a credit card to buy that fancy yacht, you can’t deduct the interest you pay on your card. But if there is a loan document that you signed that basically collateralizes the boat/home (aka if you don’t pay the loan back, the lender can repossess the property and sell it to satisfy the debt), it’s a mortgage and the interest is technically tax deductible. In most cases, the lender will send you a Form 1098 showing how much interest you paid. That’s one clue that you have an actual mortgage.

Another surprising aspect of the rule is that you don’t have to live there full time. In fact, you don’t even have to use it at all during the year as long as it’s not rented out. Note that if your second home is rented out, you may still qualify to deduct the interest. You just have to use it more than 14 days or more than 10% of the number of days it is rented, whichever is longer. If you don’t meet that qualification, you may still realize a tax benefit from interest paid, but it will be applied against the rental income you generate.

You shouldn’t go out and buy a second home, boat or RV you can’t afford just for the tax deduction, but it is worth knowing, especially if you’re looking into buying a second home for your future retirement or just a place to vacation throughout the years. If you’re thinking of taking out a loan to buy a boat or RV, make sure you shop around to get the best rates. Dealers often offer financing deals, but it’s worth it to double check that your bank or credit union can’t offer you a better deal. You can use this mortgage loan comparison tool to compare up to 3 loans and see which is the best financial deal.
