The owner is a master plumber and his company is licensed in all mechanicals and he has dozens of subs that do the high quality finish. 

The property has a laundromat ($24K/yr), mechanic shop ($7200/yr), and 2 mobile homes (owned by the tenants) on a month to month lease ($400/mo).

Truly.....odd.The insurance industry can and must, to one of your points, do better to educate clients on the underlying principals, mechanics, and ongoing use of policies designed for IBC. 

My question is, in this structure, what is the actual mechanism to account for cash flowing between the property management LLC and the holding LLC's?  

I use QC Mechanical for my HVAC services.

@Gregory Frisoli, Many times a partnership structure that can accommodate TIC ownership will also have created a mechanism where you can assume a prorata share of the debt as a TIC. 

Concessions could be utilized in a greater percentage of transactions as buyers look to reduce out of pocket expenses or offset costs to their representatives in instances where seller paid buyer commissions are not an option.High level, in the immediate future I don't think too much changes (beyond mechanics) for spring transactions.

You can also get a home warranty if the mechanicals are nearing life expectancy, or for peace of mind.Getting started is way easier than you think, and don't let analysis paralysis get in your way.

I can imagine a complicated mechanism that would produce an arguably valid 1031 strategy...but it almost certainly would create more problems than it solves.  

But if the loan doesn't allow an assumption, then use the correct mechanism for Texas to remove her from title.
