Have you checked out Dartmouth Apartments?
Or are you looking for a house that has apartments for rent? There are currently 2 available in Swarthmore, not far from each other, one is a 1 bdrm, the other is a 2 bdrm.
Also, if interested, there is a property set up like a twin ranch home in Wallingford that was recently available that has a 2bdrm apt on one side and a 1bdrm on the other side. This particular property was available for sale and asking price was $199,900. I believe that the listing contract the owner had just expired, but I'm sure the seller is still interested in selling, if you are considering buying.
I hope this helps, and if I can be of further assistance, please don't hesitate to contact me.
