Article ID: IAS10343
You can deduct mortgage interest as an itemized deduction on a maximum of two homes. You can change the home you consider as your second home if you buy a new home during the year, if your main home no longer qualifies as your main home or if your second home is sold or becomes your main home during the year. You can choose a new home as your second home as of the day the change occurs.
