Ditto to what Nate said. I also think you should contact a forester to get a value of the timber on the property. That might have an influence on the value of that portion of the property. Around here, some farmers buy timbered tracts, log it, then turn it into farm ground. They get a majority of their land cost back from the timber on some tracts.
To do the final paperwork, look at what an attorney would charge vs. a real estate agent.
