Expense write-off for our property occupied by parents?

Hello,

 

My wife and I bought a house for our parents - it's under our name, and we don't collect any rents. Is there a way to write-off the expense (e.g., mortgage interest, property tax, insurance, repairs&maintenance) on that property for us? Should we start a business and put the property under the business? Is there any other ways?

 

Thanks.
