1031 Exchange on 1 Unit that is being sold with entire building

[Carolina E.]

Hello BP!  I am currently being offered to sell one of my condo units along with the entire building complex.  I am seriously considering doing this, but not sure if it would be the smart move and/or if I can do a 1031 Exchange.  I am very green on that subject, I am trying to see how I would even start.  The building is about 30% owned by individual owners.  The other 70% is owned by a company that would like us to join them in the sale.  They have shown us possible percentages that we would get per unit.  Can I still do a 1031 Exchange if I join with them?  Also, I would like any other input you might have on the matter, not just the 1031 Ex.   Like what should I be considering.  Thanks.
