I see sellers putting too much emphasis on park owned homes and land value.  

Again, my deals were not linked to him in anyway (you'll see why I'm putting emphasis on this later).Two years went by and out of the blue he invited me to go to Vegas with him. 

Here is the actual Missouri statute (dated August 28, 2016) that answers the OP: LINKHere is the pertinent paragraph (emphasis mine):"2.

"A principal residence is a property that will be occupied by the borrower for the MAJORITY of the calendar year" (emphasis added).

No doubt in the future I might leave the MLS behind in favor of scaling business up; putting a stronger emphasis on mailings.

To be honest, it sounded like a "boiler room" type of environment with little to no emphasis being placed on facetime with clients or learning about ones area by being in the field. 

They have detailed analysis on different neighborhoods as well and get to know your criteria (cash flow emphasis or appreciation emphasis despite all properties having cash flow) because they know their neighborhoods so well and can explain and take you there.Their long term approach is what I admire, whereas other companies try to make a quick sale by hiding true costs from their spreadsheets and promising you the world and under-delivering. 

(Note the emphasis) 

Emphasis on tax returns.

You missed my emphasis on commercial real estate.
