What do you need to know? You're allowed to deduct the interest on a loan secured by your main home (where you ordinarily live most of the time) and a second home.
A mobile home, RV, house trailer, or houseboat that has sleeping, cooking, and toilet facilities counts as a main or second home, and as long as it meets all the other requirements for deducting mortgage interest, you can claim the interest like an immovable home.
for an RV to be classified as a second home it must have sleeping, cooking, and toilet facilities.
However, if your camper is towable, and not self-propelled, it does not qualify for tax breaks.
Sleeping Facilities: Your RV must have a separate sleeping compartment. Common areas like couches or benches for sleeping do not qualify. However, if your RV has a small room with a bed or a loft sleeping compartment, it satisfies the “sleeping facility” criterion.
Cooking Facilities: The RV should have a functional kitchen area. This typically includes a stove, oven, microwave, or other cooking appliances. Having a designated cooking space ensures that your RV meets this requirement.
Toilet Facilities: Your RV’s bathroom must have a fully-functional toilet and sink. Additionally, there should be a station for showering. An enclosed shower or a detachable shower head is acceptable. While luxurious features like a jacuzzi are not necessary, having basic bathroom amenities is essential.
