You lived in just a single room in a house provided by your employer? Is that as awful as it sounds?
It's a pretty big room. I haven't officially measured it, but it's probably 3x bigger than the room I grew up in. Have my own bathroom and full refrigerator, and the hallway connecting the bathroom to my bedroom is basically all mine as well (that's where my fridge is). Only space I share in the house is the kitchen and the washer/dryer.
It's actually a pretty nice setup. Got enough space for a closet, a garment rack since the closet is not big enough (I have way too many clothes), a couch, a coffee table for the couch, a queen size bed, an end table, something I use to hang my coat and store my shoes, a table for my TV, an extra chair for guests, and two chest of drawers. And I still have quite a lot of open space in the middle. In the room I grew up in, a full-size bed is as big as I can fit. If I tried to stick a queen size bed in there I'd barely be able to fit anything else.
I'd have to drop $1200+ on rent around here (which is A LOT for the area) to get a bedroom as big as this. Of course obviously that $1200 comes with more square footage than my bedroom but you'd have to add utilities (electricity, heat/AC, water, etc.), internet, and TV on top of that $1200+.
I'd gladly stay at this house and pay the rent, which would be less than $400 a month (which includes everything - utilities, internet, tv, etc.), if they would allow me so I can save up the money to eventually buy a house or townhouse. Wouldn't even think twice about continuing to do this if I got the promotion. Alas, that will not be an option. I'd only move out to rent someplace else if I wanted to live with a serious girlfriend/fiance/wife.
