The general advice is that you can afford 28% of your GROSS monthly income for a mortgage. Why isn’t it NET?

Just trying to see if I am missing something. Wouldn’t it make more sense to calculate based on the NET, the money you actually see vs the gross which is irrelevant in real life?In my case, I make $6500 GROSS a month, or $78000 a year. My net income is $4000 though after taxes, 401k, health. Using that equation, I can afford $1820 if I use the gross amount or $1120 using the net amount. It’s a huge difference. via /r/personalfinance https://ift.tt/2yOTa81
