The last thing you want is to buy a mobile home in a neighborhood where you don't feel comfortable which attracts residents and clientele that don't fit your personality. 

Which is part of what makes them so attractive to real estate investors (the other part being that they offer long term financing solutions when it used to be so much harder to get get long term financing on rental property).

I'm trying to understand the geography and the attractiveness of particular locales.

DOW Index Fund would give you 11-13% returns and you would just have to keep breathing to make the money.

Flat hides the most, but it also attracts dirt, so depending on how long it takes to sell the house, you may have hand prints everywhere that you will have to frequently touch up.

Need some cash to put into the property to attract renters in the shoulder seasons-May and October and November.

The other location I listed in STL is based on my proximity and the landmark attractions in the area.

Especially when looking out of state many investors find Memphis attractive due to the cashflow opportunities that are available here in the city!

What's going on in Lafayette that is attracting new investors.

Sounds like you just need to take a deep breath, get your second wind and finish this marathon!
