Asking for 1031 best tips for closing on multiple properties

[Patrik Kusek]

HI everyone, I'm beginning a 1031 exchange and selling our condo in CA to diversify into multiple midwest markers. 

If you have done a 1031, closing on multiple properties at the same time, what is the single most important thing that an investor needs to know about doing the exchange. The obvious issue of timing has been drilled into me by just about everyone. So lets go beyond that please. Im looking for real life experience, the good, the bad and the ugly. Thanks!
