How can you have such a low mortgage payment?? That's a typical car payment these days.
Because he/she likely isn't living beyond their means. $600 car payment if you want to keep up with the jones' or have the means to do so.
Start out small, then work your way into a larger home if that's what you want to do.
Get a reliable vehicle to take you to and from work and get groceries, doesn't need to be a brand new vehicle or cost $40K.
Better get with the program now and save/invest your money. Otherwise when you retire you will learn real fast how quick that money runs out.
If you feel you need a big, new home and a fancy car, by all means...go for it. If you have the funds to do so, more power to you. ...I have no issues with people with nicer things than me...it's your life and you can live how you want.....I think thats awesome.
If you get a good faith estimate and buy a home for that price....then you are foolish...unless you have other funds set aside.
You should be able to pay your mortgage with one weeks pay, combined you or you/spouse..two weeks at the absolute most and that's pushing it.....that's danger territory anyway.
