We track land sale values throughout soma and the mission, and are involved in the sale of many development parcels. Unfortunately, those values from even as recently as 6 mos ago mean little today since the market has moved significantly. In the Mission, in particular, zoning determines value, as does location of course. We would be happy to give you a sense of value over the phone, feel free to contact me, tniu@naibt.com 415-568-3423

you should try contacting Randy at First Amercian Title who can pull the sale comp http://www.rofo.com/user/rsierra11 and track down the broker.
