How To Find Land Value?

[Blake Grzybowski]

I'm starting out in wholesaling and I have a seller looking to sell a property where the home had a gas explosion and is completely destroyed. I tried getting a price out of the seller, but they have no idea and are completely lost in the whole situation. It's in a very nice neighborhood near a golf course and great schools. Homes in the area are selling for around $450k-$500k depending on size (3k+ sqft, 3bd+, 2ba+). I haven't called any builders and plan on doing so, but I just wonder if there is a quick, dirty way for me to get an idea on the land price outside of the land value on county website? I posted this in another forum but wasn't sure which would be the best spot so I'm putting it here as well.
