Land deal?

[Cesar Garcia]

I'm trying to figure out if this is a good deal, I ran into a guy that wants to sell 30 acres of land, he had it appraised at 375k, city assessment is $281,431 he wants 150k and is willing to negotiate, this is in a rural area in California (mountains), houses there sell over 1m in smaller lots, I'm really not familiar with land, so any advice would be appreciated. Thanks.
