You need to consider the adult size.

My cousin's son brought home this cute little iguana. Four years later, it was 6 foot long! At that size, most people convert an entire closet for the iguana, if not an entire room. They LOVE to jump, and he could go up to the top of her entertainment center.

She gave the iggy to iguana rescue. He is now owned by a person who has a total of 5; the entire basement is devoted to them, and a large outdoor enclosure for their use in summer weather. He is one of the lucky ones, he got a good final home.

There ARE reptiles whose adult size is still in the inches - less than one foot. I would think you need to lean towards that type of pet!!!!

Just my thoughts.
