Hi roaming,
I did have to pay for my upgrades. There have always been upgrade options, not just now.
There are some issues with the building, but nothing more than I typically expect from a new building. Most of the management issues should be ironed out soon, since the building is now registered, we can elect our board of directors/figure out property management. Other than that, I guess construction was a bit slow, so PDI issues were slow to get fixed (I know some units are still under construction).
Regarding occupancy, I'd guess it's in the 50-75% range right now, obviously I don't know for sure. Seems like a lot of empty parking spaces at the moment so that's what I'm going by. I think maintenance costs were set by the sq. ft, so don't think they'll be adjusted at least for a year. Hydro for my place (LPH, ~1000 sq ft) is about $100 per month.
Hope this helps (some stuff may not be 100% accurate, but it's what I was able to gather!)
