Hi all!

this is my first time posting so if I goof on etiquete or post something in the wrong place let me know! Thanks. 

I own a 8 unit apartment building with my sister as tenants in common. I would like to buy her out and own the whole building. Can I sell a duplex and use a 1031 exchange to buy my sisters ownership?

Thanks 

Jorge
