I was under the impression I wouldn’t need money because the contract would be assignable....therefore before closing I would contact my cash buyers to take over the property....what am I missing?

I had lived in mine as a primary residence but i was under the impression it didnt matter, as long as you are requesting it for a non owner occupied. 

My impression is that housing price took a bit hit after oil price crushed a few years back. 

My impression is that the most "typical" range is from 40/60 to 60/40 and this would fall towards the higher end (and may well be justified as the sponsor has a solid history of successful projects).

According to this article, the region added 3,348 jobs last year which is quite impressive.

Congratulations on accumulating such an impressive collection. 

This is a common negotiating tactic especially if this is the second or third number given, it is meant to give the other party the impression that this is your final offer (even if it's not). 

I'm impressed. 

I'm impressed that you are buying 24 units with very little knowledge.

Beyond that, and the most impressive part is that you have defined your "why".
