First guy did the framing for walls and layout of the basement, the door frame was too small for the door so it won't fit and he did the tile without cement under it.

Especially if they do not want it in their neighborhood.

Location is fairly good, land is on a major rd and the back part of it connects to an established neighborhood with older brick SFR’s All units a tenant owned, utilities aren’t included and overall condition of the park is on the low end.

The neighborhood is great, never had any issues whatsoever.

Do you have a PM out there who can tell you more about the neighborhood.

I commented in another website about asking a couple of friends of mine that through the day are working in neighborhoods to let me know if they see any vacant or distressed properties.

I was intrigued by the topic of "opportunity zones" discussed on the BP Podcast episode 269 (the one about RE & taxes).As I understand it, it seems almost like a "1031 exchange" type of investment vehicle but rather than property<>property, you could use other equity assets like stocks or mutual funds to invest in designated opportunity zones in low income neighborhoods via opportunity zone funds.

My plan, detailed below, was to purchase houses in good neighborhoods/schools etc. at below our means that was around an E6/7/O3 BAH rate and then rent it out for the long term for either when we moved back, or appreciation over the years. 

The answer to your "fully occupied" question likely depends largely on the Owner-Occupier vs Investor market in that particular neighborhood (eg. desirability of school district).

For the first question, homes in the neighborhood are going for about 8-10k more with the finished room then not.
