Your 1031 intermediary may be able to suggest lenders.That said, make sure that an exchange is truly beneficial for you.

If this is your plan I would start talking to qualified intermediaries soon.  

'Identify' doesn't just mean you make a list for your own notes, you have to have Qualified Intermediary in place and they need to be aware of, and properly document, your selections.2) you must purchase your replacement property within 180 days CLOSING on the sale of your current prop.Why am I yelling about closing?

That is true an unrelated 3rd party called the qualified intermediary is required to document the 1031 exchange on your sale and purchase and ensure holding and transfer of funds. 

Is it easier to have her obtain POA to complete this sale or continue having her be the intermediary and sending documents back and forth?

I’m located in Central Florida and looking for recommendations for the following professionals with experience in multifamily investing:Asset Protection AttorneyCPAInsurance BrokerContractorsQualified Intermediary for 1031Mortgage BrokerIf you have any other great people I should talk to I’m all ears 😊

The qualified intermediary role is filled by someone like us. 

As you work with cash investors, it would be great to either get their contact info, or to reach out to you as an intermediary with any deals I'm looking to assign when the time comes.

You'd need to speak with a Qualified Intermediary to execute a 1031, and they will make sure everything is as it should be.If you were to execute a1031,  you would defer taxes on the gain and roll everything (total value AND total equity) into new a prop(s).

Consult with a CPA and qualified intermediary needs be involved too.
