Investors & landlords

Thank you. A couple of questions... In Turbo Tax, the purchase option asks for purchase date, escrow fees, etc. These do not apply in our situation. For the purchase date, do we use the date when construction began or the date of completion?  Do we indicate $0 for the escrow questions? 

A turbo tax phone advisor told me to list this as a room addition and list the building costs as "room additions total".  This seems to work, as the result shows our building costs as our depreciable cost basis.
