I'm single, salary of $72k (yeah, yeah...insult me...have fun). I put 25% of my salary into retirement accounts. Using the rule of not letting mortgage payments north of 25% of your take home pay, I'll pretty much never be able to afford a decent house.
The only apartments I can afford under this rule are roach infested dumps like I'm currently in.
And they don't build houses for single people. I do not need 1,500 SF.
