So I wonder what is the motivation for folks to be using vrbo 

Very cool and motivating! 

Everything going through my mind is around securing our income during retirement and leaving some sort of inheritance to my children. 

Is there any way to file a change of use permit of some sort that would make this business model work? 

Also, you may consider writing contracts that have a processing fee put in place for client that "OPT" to "NOT" pay online as a motivating tool to sign up for online payment.

I was climbing the charts, but Jay was so far ahead that I lost all motivation.

In exchange, I’d be able to be sort of an intern or someone to help with boots on the ground here in AZ.  

@Monte Bolds congrats on being so motivated and setting your goals.

Buy or inherit and hold all their lives while working the properties for income.I've seen teachers, firemen, software engineers and all sorts of people utilize both strategies successfully.

Their main goal is maintaining wealth not creating it, so they are diversifying through all sorts of different investments. 8% returns are on the high side.
