I would hold off a while.
Baby bloods can be mean as hell. LOL
I just got a couple this year. Both have bitten me and I'll take some more bites.
My biggest one is calming down. They are both 2012 females.
I think both of mine will settle down into nice tame adults.
I say wait til you move out in a few years. Just my opinion. Out of respect for your parents, etc...
I've got an 18 month old daughter and a new baby girl on the way. My snakes are in lockable cages in the spare bedroom with the door locked. Me and my wife both have keys. I keep BP's, 2 baby bloods, and boas on the opposite side of the room.
I will say that blood pythons make awesome captives/pet snakes. I like them a lot!
