OMG, 500W daytime 13W night on 1520?? I doubt the translator is worth $350K in that market, but the tower, assuming it's not a hollow center complete rust-sickle, together with the translator, might be worth it. The AM, though? Ugh.
If the land and building isn't part of the deal, my advice would be to; RUN AWAY!
The original owner of that station just died last year at 98. That frequency has a very interesting past.
