Investors & landlords

i bought the condo in April 2007 and lived there until Oct 2010, converted it to rental after that. my tenants moved out in Sept 2018, i put the rental for sale after that and it's sold in June 2019. 

Some posts i read here said the time the rental was vacant cannot counted as rental but personal use. so I listed the sale as Sale of business, and split and cost and price between business use and personal use, only problem with that is i cannot report suspended PALs  for rental. 

So now you say the better way is to still report it as rental just don't report any income, can i report the mortgage interest and real estate tax I paid in 2019 there?  because I still have a 1098 form in 2019 for that property.
