Military pay and housing?

my husband is looking to try and enter the military (either coast guard or navy). we are married and have one child. but before he contacts a recruiter i need to know some truth. recruiters will say ANYTHING to get you signed up and then when or in, your stuck no matter if he bold face lied or not. so, how much do you think he would receive monthly and is the housing on base as GREAT as they make it seem (with all the huge two story houses in cute, quiet neighborhoods) or is it a crock?
