If I set up the transfer on a Monday, it's deducted from my bank account on Monday, and she'll receive it on Wednesday.But the way I see my service, Clearnow works, there's an intermediary step.

Did you use, and can you recommend a Chattanooga 1031 Intermediary Service or CPA?  

The cash letter is probably from their Qualified Intermediary to prove they have a cash position in their 1031 Exchange.The 1031 Exchange will not hold up the escrow/closing process.

I don't act as intermediary. 

@Steven Ko definitely hire a 1031 intermediary, you want to be careful not to break any of the rules

What, does his attorney want to charge you an hourly fee to be the intermediary for the proverbial clogged toilet?)

I am looking for a 1031 Exchange Intermediary to discuss some specifics on a property that my husband and I are hopeful to utilize a 1031 Exchange for.

Well if we are worried about the transaction being arms length you could involve a bank as an intermediary like most swap arrangements do.

It is fighting to protect its status as an intermediary in the transaction and not get dragged into enforcing the cities regulations.

Engaging a qualified 1031 intermediary (note you do not want to personally receive proceeds from the exchange as they may be taxable or even disqualify the transaction.
