Landlords can move in for personal use, but not as a way to evict a tenant. Seems perfectly fair to me, security of tenure is something that benefits the whole community.
Not really when people feel entitled to live in the downtown area at an extremely low rent. For example, someone new moves in for $2400 for a 2 bedroom whereas a person who has been there 20 years is paying $1300. The new person ends up having to subsidize the tenured renter and the landlord also is not able to maximize their profit. Then a big corporation can come in and buy the property because a landlord cannot maintain it well enough. The big companies have their own renovation teams who they own so it's profit to maintain it whereas the smaller landlords end up having to pay a 3rd party and they lose money. It's a delicate balance. 1.9% yearly increases and up to 4.9% on capital expenditures makes it a challenge.
