A : The pros of a short term lease are well, it's short term. If you decide to live there for three months, you aren't obligated to stay there any longer than three months. If you like to move around a lot, that would be a good option for you. The cons are that it can cost more per month than signing a longer lease, you might have to be moving heavy furniture more often than you would like, and it's hard to make a connection with your neighbors if you live there for such a short time (this might be a benefit if you don't like your neighbors though). The pros of a long term lease are it might cost less money per month when signing a longer lease, you can get settled in and be comfortable in your apartment for a longer period of time, and you don't have to be on a constant hunt for a new apartment! The cons are that it is hard to break a long term lease if you need to and you might not like where you are living and you can't move. In Boulder, I only know of one place that offers a short term lease and that is Canterwood.
