Evaluating MH market, what and how?

[Walter Pape]

Preference this post that I am still in the newbie classification and researching what area that I want to focus on. I live in the Tampa / St. Pete area of Florida. There are a large number of MH Parks in the area. I have started looking up MH on craigslist.com, realtor,com, and a couple of other sites. As I am evaluating the market there are MH that are 2/1 built in the 60's and 70's and a few 1990's that are either 2/2 or 3/2. The prices vary from 7,000 - 53,000. There are a few with land but I don't know enough about what to do if I were to attain these properties.  

How did / do you evaluate your market? 

Am I evaluating the market correctly? What am I missing?
