That is a tight budget for a 1BR apt. You may be better off renting a room for a while and saving money, increasing your income when opportunities become available to you, and then when you can increase your budget so you can qualify for $600-700 per month, we should be able to find you a comfortable 1BR apt somewhere in North or Northeast Philly. Maybe even South Philadelphia too.
If your interested in a room in a nice house, fully furnished, please call Izak at 215-833-3920. He may have a room available for rent. Good luck with your search.
All the best,
Larry Lichtman, Realtor
