It used to be a grange meeting hall so it's basically a big empty room inside (a blank slate!).

Any rules of thumb for $/sqft to build a blank space apprpved for a commercial use?

I definitely can get trapped in the analysis paralysis vortex on occasion.

I have had land me the deal in the current market in more than one occasion! 

I know Michael Blank, Rod Khleif, Jake and Gino, Jason Yarusi, John Casmon, among others cover a lot of good information on apartment investing

My current tenants seem financially stable, but in the past I've had tenants whose rent payments bounced on occasion. 

If your not paying utilities then all of those remain blank.

People talk about Kansas City or Indianapolis or fill in the blank as a great market but like most cities, there are good areas and bad areas.

I had to have a friend help me fill out my first lease for my first tenant (I didn't even know where to get a blank lease).10 years and 1000+ units later, I still feel like I don't know what I'm doing.I bet 10 years from now you have **WAY** more units than you think. 

Start with books/podcasts - Wheelbarrow Profits, Michael Blank, Todd Dexheimer, lots of good apartment books and podcasts.2.
