Is it fairly priced for the size, location, quality, and other factors?

I'll drive you down the streets of Lehigh acres where they build and show anyone the gap between market rents (real asking prices) and their pro formas 

Driving through Matlacha to get to Pine Island was particularly tough to see. 

Note that the diagram doesn't consider tax implications—that's another important factor you'll need to include in your decision.

Conveniently located in Bryan TX, within walking distance to A&M Bus stop and a short 5 minutes drive to College Station, home to the largest university in the state, Texas A&M.

I removed our debt (P&I) all other expenses have been factored.

I can't always be there for my projects, so as I'm trying to implement a system that allows me to always factor in a GC. 

A lot of factors go into this. 

Most of the designers I have have sort of a baseline price i.e $2.50/per foot but it can go up or down on other factors

Never fully trust anyone that isn't willing to share the negative aspects of all this.As I'm sure you've experienced, this can be a very rewarding path to take and depending on your grit and determination, overcoming all the pitfalls are well worth the effort.Cheers and drive safe!
