> We could afford our expenses on two minimum wage jobs if need be. And that's with 3 kids.
Let's assume a $15 minimum wage. The housing one can afford on two such wages is $1,560/mo. On a $700k home, assuming 20% down, to repay the principal alone is $1,556/mo. A mortgage calculator says $3,800/mo once you have interest in there — or 73% of your gross income. And that ignores insurance & taxes. And those 3 kids.
