We are considering joining a couple mentor groups to build relationships with more investors.

Major league franchise and we're building a new arena.

A lot of buildings don't have a carrier willing to insure at all.

Go to BUILD YOUR TEAM at the top of the screen and look for local investors or meetups in your area.

You have to know the market before you build a plan and I don't think this market supports your intended plan.

Went on to purchase additional rentals so tenants can pay down the loan and I build equity How did you find this deal and how did you negotiate it?

Those special assessments will not be enough, and the reality is the association will likely be taking debt to approach these projects (eg. paving the parking lot, residing a building) and that financial burden would be on the owners and the association. 

I have been told by a contractor that the foundation of the building is intact, so it does not need to be torn down but requires a "gut renovation down to the studs."

You can play with it and build up a 3d walkthrough.

Also, would this loan help build my personal credit, or would it only report to business credit bureaus under my LLC?
