Or a short term rental fund in an overpriced community, a self storage fund in the backhills of pick a state, an ATM fund to invest in ATM's ?

You said you went through a turnkey place, but did you actually inspect them yourself or did you rely on the inspector they picked? 

I have a replacement property picked out already and an accepted offer on it.

The reason this is so important is because when you pick the right property after research and due diligence you'll say hey this is great, let's do more!

The biggest thing I have learned is to pick your market intelegently.  

The short version is if you go with the Midwest, figure out which are Class A, B, C and D areas and I recommend picking good neighborhoods (Class A and B) with good schools and go for appreciation. 

Any advice on how to pick which location to jump on first??

Pick a nice bright color for those, like teal or red.

I also don't have time/no one will hire me to pick up a second, part time job which makes in difficult to increase my income.

Lots of good points out there, but hard for me to go back and pick out who said what . . .Some clarification from my view point:  I'm not really an 'investor' (maybe some day)  I had 1 SFH rental - more out of necessity, cuz I didn't want to sell at/near the bottom after having to buy (also out of necessity) at the top-top-very top!.
