Some people don't do well with caged pets - my husband is one, but he knows it's a psychology quirk in him, not a real problem for the animals.
My advise would just be find somewhere they are legal. Ask to see their pet policy. Inquire about caged pets, and/or reptiles. If they push for information or you can't evade, don't lie. You'll find somewhere. This isn't like trying to rent with a large dog. I would advise, however, to go with a leasing agency/rental COMPANY rather than an individual. Policies covering lots of properties or units are going to likely to be WAY less biased than talking to some individual and your ability to rent with a snake depending, basically, on how they feel about snakes.
(I will be keeping my kid's snake when he leaves for college in a couple of years. Not going to lie - I am going to be really sad when the snake goes. I *am* attached. Reminding myself that I can get a new one then might get me through it. Maybe.)
