I might not have to worry about rent/utilities, well maybe I do, but my mom doesn't want me to move out until I get married. It's a good thing and a bad thing, good because I wouldn't have to worry about rent and food, bad because I won't be able to bring home a different chick every weekend.
But considering the fact that my mom and dad are probably not going to be together much longer, I'll probably chip in when it comes to household money. Other thing is that, when we bought our house, it was pretty cheap ($248K). We made some modifications to the house, and property values have skyrocketed where we live, so we could actually sell this thing for ~$600K and then move to another place with a lower cost of living.
