The other issue is moving mobile homes is fairly expensive. 

As long as you are abiding by the Fair Housing Act and not making a decision based on any protected class, I think you can ask anything you like (e.g. do you play chess at the grand master level?

Example, bedford texas was 4 days on the market avg, i got my money back in fairly fast time,6% usually was 12%.

Your skills are as a CPA not a realtor so that should be a fairly easy answer, and it is not mandatory to have a real estate related job to invest in real estate. 

I personally like to have multiple units so your risk is mitigated a bit, and to be fair I am a multifamily guy not a commercial investor. 

To be fair, all those predicting doom could very well be right...this year. 

I am a fairly new investor from Jacksonville, Florida and recently closed on my first multi-unit property!

Thank you in advance1 I am also fairly new so I can give a few recommendations with what I started with.

Fairly cheap to set up. 

My concern with your park would be how to make the numbers work with only 8 homes  Rents would need to be fairly high and/or price very low for these types of deals to make financial sense.
