I purchased 4 condo units this year, all in the same building. Do I need to prepare 4 T776s since there were 4 individual purchases for the 4 units?

I made 3 separate purchases for condo's in the same building. One transaction for 2 units, and 2 more transactions for 1 unit each. Do I need to fill out 3 T776 forms?

Also, do I put the purchase information in the "Equipment and other property additions in the year" section or the "Building additions in the year" section?

Thanks!
