If you are "transacting" in a state, some states (mine in particular - Illinois) require you to file an "authority to transact" business which in some cases costs more than the LLC itself.

How would that transaction work?

So the more tax you can defer over time the more income you'll make over time from the deferred tax.A 1031 does require the use of an unrelated 3rd party to the transaction called the qualified intermediary. 

@Dan Weber thanks for your response, I am so disappointed with my broker that the thought has crossed my mind.

In the larger business space the ERP system would use a finance module to maintain vender relationships and all interactions and transactions with them.  

Spend some money to help facilitate that transaction and help the person solve a problem.

I would wait until you close on the Florida condo before getting into a loan transaction a new purchase.

The mortgage (Rocket) is about $87k and the Zestimate is about $167k.I'm currently working out of state and am looking at buying an old trailer and land for about $40k.How would I go about handling this transaction?

Which is the best way to record these transactions ; as a intercompany asset - intercompany liability or as A/P - A/R?

If they are not in the state of business activity then it again generally needs to be registered with the state of the business activity otherwise it doesn't exist for lawsuots in that state which defeats much of the purpose of having one.You can have nested LLCs depending on your needs but that is generally used for high equity transactions, say $1m or more.
