The Redevelopment Authority makes every effort to produce and publish on this site the most accurate and current property information available to it. Our ownership records are based on deeds as recorded with the City of Philadelphia Department of Records (DOR), and we are continuing to revise these records as often as we are able. Please notify us of any inaccuracies. The information on this site is not intended to indicate the quality of property or priority of interest in any property; you are advised not to rely on the listing for this purpose. Properties listed as available will be verified by staff once an Expression of Interest is submitted. If staff confirms availability, we will request that a certified check be sent in to cover appraisal cost for establishing market price. Appraisal cost will be dictated by the lot size; the typical fee for a residential property ranges from $300-$600.
