Hey Bob, thanks so much for the quick reply!

I'm pretty sure they worked with a facilitator, but I've reached out to verify, though I'm receiving everything pretty late, and haven't had much discussion with the client.

From what I have, it definitely wasn't broken out into two separate transactions. 

You are correct, they are living in the new home, and I'm currently showing a little over 400k in capital gain. By separating out the business portion of the proceeds, I would be able to reduce the capital gain, then I would treat the remainder of the proceeds as a main home sale exclusion, right?

That being said, I wouldn't be able to take the home sale exclusion within the like-kind exchange without the proceeds of the home being separately identified?
