For retail, last 2 years were very bad and things are slowly improving now. I am actually now noticing that many vacancies are going away with new stores moving in places which were lying vacant for one or two years.
There is still a long way to go before all the malls fill up though…
For offices though things might be different. I don’t see those “for lease” signs going away and for some reason they still keep on building office towers in the city.
