strike up a conversation with the residents of the park and ask them how they like the park? 

Most agents are thinking retail price for primary residence when setting a sale price.

You are just not getting private money for anything deemed as primary residence to you.

At least if they do find out you have an illegal unit, you can offer your alteration as a possible solution and claim ignorance, vs blatantly ignoring today's rules to put in something equally illegal.

All non resident aliens must file and pay state and federal taxes on business income.

My primary consideration is time so your situation may require more high end solutions due to your price point.

We really do not want to have to live in the residence for a set period of time before we can flip. 

I have a great deal of knowledge about my market if anyone was in fact interested and had the capital to invest that I can certainly share, as I'd love to network with those that reside in VA and those that do invest out of state.

Hey David,Google my remodeling solutions name and you'll find my cell. 

I do own a personal residence in Castaic.
