Passthrough Okay Before Downleg Close? 1031 Disqualified?

[Aaron Moayed]

If a seller wanted to take some cash (boot) out of a sale via buyer's passthrough, does this disqualify the seller's ability to 1031 exchange, or is that simply tapping into proceeds after downleg close that disqualifies an exchange? My client wants to use some of the money on a passthrough deposit, and I'm seeking clarification on if this is possible without disqualifying the 1031. Thanks
