At what date can a landlord start deducting mortgage interest and other rental expenses for a rental property?

A landlord can begin deducting mortgage interest and other rental expenses for a rental property as soon as the property is placed in service, which generally means the first day it is available for rent. While specific dates like July 20th might seem arbitrary, the timing of the property being available for tenants is what dictates when these deductions can first be claimed. If the property is ready and actively being rented or is available for rent, the landlord can start claiming these deductions from that point forward.

Any mention of specific calendar dates such as April 1st, July 1st, or September 15th lacks a direct connection to the tax regulations surrounding rental properties. Deductions hinge more on the status of the property rather than a fixed date on the calendar. Thus, understanding when a property is considered "in service" is crucial for claiming the appropriate rental-related deductions.
