Best Mobile Home Park Markets

I would appreciate it if anyone could give some input on where the best mobile home park markets are. I read an older post a little while ago where it was mentioned that park owners in Michigan are probably hurting right now. That makes sense due to the unemployment rates there currently, but I was wondering which states/areas typically have the most success with mobile home parks. There may not be a straightforward answer, but any input would be appreciated. Thanks.

Also, I was wondering from an accounting standpoint what percentage of a mobile home park (on average) is depreciable? Also, is the period of depreciation over 39 years? Thanks.
