What kind of family demographic would most likely be interested in a higher end mobile home solution?

After all, like you said, the job allows them to work anywhere, anytime, which is a HUGE perk for some people.My recommendation would be to put an ad on Craigslist and keep an eye out for stay-at-home-moms (I don't think you can advertise for that, but that's the demographic I would look for.

city-data.com is a free website that offers information such as demographics and it also has links to local forums with discussions about the city.

The demographics have changed in the last 25 years.

There are places like used appliance stores and Habitat for Humanity that have very cheap appliances.With all that said, I am serving a fairly low income demographic.

Ill add another factor to consider and that is this:Which properties will appreciate faster (thinking about school districts, demographics, jobs in each area etc) and which properties will you be able to perhaps improve some and increase the rents?

Demographics are important, as well. 

Took a virtual drive around the area via google earth/mapsLooked at demographics, market rates, market analysis, crime report and future prospects Its not Indianapolis but its a small city. 

Training section 8 tenants is much more difficult, verging on impossible in many cases, than your normal tenant demographic and their mindset/attitude often makes intensive hands on management mandatory. 

issues like migrating demographic groups can impact negatively on your apt complex as well right?
