Which is better for a tree farms under 200 acres, setting up an LLC or LFP?

I'm not sure that acreage is the main driver in the decision here.  You should consult with an attorney for the pros and cons of each of these types of organizations.  There are potential valuation issues and you should be aware of that before entering into the process.  There are differences in how states view each of these organizations as well.  I'm sorry I can't provide a more definitive answer for you.  It's not an easy question.
