There are lots of good areas around KC, but if you're new to the area, then I'd be glad to help you narrow down what makes sense for you.

It will be necessary to contract with an attorney to set up a 506(b) and file the correct documents.

This question right here will narrow your focus on your target market very quickly. 

I’m currently looking to get into single-family homes and have narrowed my choice cities to 4: Huntsville Alabama, Indianapolis Indiana, Kansas City Missouri, and Oklahoma City.

In addition to moving to the market where you're planning to invest, you have to define/narrow down your investment criteria in terms of the properties; size of the properties, specific geo locations where you'd want/don't want to go; etc...

I would advise against trying to go with 1 source since that will narrow your deal flow considerably. 

We did this as a band-aid fix, expecting to go with tile eventually (concrete subfloor).

I've spent 6 months researching TKs and have narrowed it down to Memphis Turnkey and Memphis Invest; both of which have received positive reviews here on BP.  

However, I am a one-man-band currently and bookkeeping became a nightmare.

B and C properties are safer, you can still generate great COC returns without all of the headache and you can spend all of the extra time finding more!
