I don't know if you are into this idea but college fraternities often allow pets. Maybe you could look into that when the time comes.

I agree, don't break your lease. The consequences outweigh the benefits.

You could talk to the landlord about it and see what he/she might say. They might let you slide if it is a reptile kept in a secure location. My landlord was very understanding even though we have a "no pets" policy. She was perfectly fine with us having reptiles.
