Read the small print with what you sign here. When you move in here, they make you sign as much documents as you would to buy a house. They will catch you one way or the other before you move out.
We rented for a year and had to extend (sign a new lease for an extra 3 months for a much higher rate). When it came to the last few days before we move out, they told us that we still had to give 20 days notice so another 2 weeks to pay at the extremely high rate. I was then told that the reason was that they could not advertise the apartment without this legal notification. It's funny how I have been renting for over 10 years in the Seattle area and have not come accross this before. This combined with the fact that there are numerous apartments vacant.. Just another way to extract money from the tenant.
