i've heard from my parents that many new buildings are still empty because the rents were too high (more than 8000), and slowly the prices have been coming down. this is all from word of mouth though.

i doubt landlords would lower the rent if their buildings already have occupants. this would probably only happen if the occupants left and they needed to attract someone else to rent the place.
right now we have a 2 bedroom apartment for 7000, and this was a super find last year. 5-6000 sounds more like the upcoming norm. what do you think? :)
