Selling coop(1bd) and buying coop (2bd) in same building at same time

[Lily Ochoa]

Good Morning all, am in the process of selling my coop first per loan officer and will be buying coop (2bedroom) pending sale of unit on contract we signed- my question is when I do my taxes will I be hit with anything ? I lived in apt since 2007 will be closing before or same day. Any advice what to expect or should everything move smoothly? 

Thank you in advance
