When we sold some of our timber we sold by the board feet. Their are at least three scales used to determine the amount of board feet in a log and each scale produces a different value.
I THOUGHT that the only time trees were sold by weight or by the cord was for firewood or pulp but this might depend on what companies are doing locally.
Pines trees in my area grow much denser per acre than say oak. The pines also produce more board feet per tree than the oaks. So pine will give more money per acre than oak.
When we sold, we managed to sell at the peak of the timber market which was $400 per thousand board feet. I checked the price a couple years ago and the price was $200/MBF. M is thousand aka Roman value not modern digital value.
I cannot remember exactly but it seems like after expenses our timber sold for about 2/3's the price of the land.
So their price is POSSIBLE. But given what I THINK I know of current timber and land prices it is doubtful he got as good of a price as we did. NC used to have a phone number, and I think know they have a website, showing what the price of timber has been in different regions of the state over the last couple of quarters. You might want to check to see if FLA has this information available.
The WSJ had a story about politics and property values in FLA. Houses in Volusia county dropped from an average of over $200,000 to $98,000.
My guess is he got what value he could from the trees and just dumped the land to pay off the mortgage.
We looked at some land before we bought ours. The two guys selling the land were going to timber and then sell the land. This seemed to be their way of making money. We offered them asking price for the land if they did not timber. They said no. So did we.

We saw a couple parcels where the trees had been timbered and the land was then sold.
