Is it really take like a year or two to get a house inside the base? My husband is a senior NCO 

How long do you wait for to get a house inside the Ramstein base? 

2-4 years (wow!) for SNCOs on RAB. Less of a wait on Vogelweh or Landstuhl post but you're going to be off-base for a while regardless.
