Thanks to Terry Doloughty, PHCA, the PCRG VPWG, the URA, and the City Finance Dept. After 4-5 weeks of inquiry, the discovery process for the new owner turned up a name: Ledonne Construction. They bought two properts at the September sherif sale: 329 Hanock and 3212 Downing St. Google Maps puts them on Route 19 in the North Hills / Perrysville area (near where I grew up in Ingomar, PA). They are on LinkedIn.com but outside of my network. PCRG/URA was nice enough to query the entire county for properties owned by this group: several properties in Lawrenceville and Penn-Main. The PA DOT corporation database (and Google Maps) puts them at 3109 Ponderosa Dr, Allison Park PA 15101, a residential street in Alison Park near Rt 8 and Ferguson. PHCA has a letter out to them to discover their intentions.
If our assumptions of a mixed landlord / construction company are correct, we're having trouble understanding why they would be interested in a redeveloping 329 Hancock given the volume of work required to make it inhabitable and profitable as rental space. Its also possible they have a grand vision for housing. ~BAS
