Sound advice, we just gave the same advice to our kid who's buying his first house. Other advice was to make sure the payment wasn't more than 1/4 of his income (not counting his wife's income.) Those were the old "rules" and they served us well. Today though rates are so ridiculously low and house prices so depressed, that his payment is about what ours was when we bought a house 25 years ago...but his salary is at least twice of what my husband's was when we bought our first. Who'd have "thunk" it.
Yes, but you also have to consider that money today is a lot less valuable than it was when you and your husband bought your first house.
