I hate to say this as i am giving out personal info, but I am a apart.mngr. It is usually a safe bet if it is within three times your income. For example. You make Three thousand a month, you can afford a thousand month rent
Rent used to be 1 weeks income (25%). Now it's a little over that ((28%). So if you make $800 a week, your rent should be no higher than $826 $800*4=$3,600 $3,600*.28=$826 a month Please don't fall into the trap of "I could eat less food or I wont run the air or heat." It never works. Good luck!
