No one can pay a down payment on $30000 a year ($2500 per month). No bank is gonna give you a mortgage with that.It's according to what your definition of "live one' means. I know many-many that lived quite well on that and many on less than that yearly and the proof is visible when you ride by their brick homes with 2 or more cars in the drive ways and maybe a boat and camper in the yard also.
For many $31,133 per year afforded them a nice life if they lived within their means and didn't try to keep up with the Jones's. Meanwhile you throw your money away on Rent and may never own anything, that's your fault.
