I'm sure it's a nice parcel of land. I've seen the north end by plane and although a lot of it is covered with bush, what I could see looked nice. As you said it still needs to be cleared.
If there has been a recent survey done, then that is a plus. Although the price per acre (22,500 approx.) is not bad, buying the whole tract for $1.2 mil may be difficult for anyone except a developer or a very wealthy individual with money to burn.
With the terms of the deal, the payments would work out to around $9,250 US a month for 120 months. Not to mention the total interest paid on the loan would be around $460,000 US. There would be no way I would pay that kind of interest...ever...on anything.
Is the owner willing to divide the parcel up? You may stand a better chance of selling that way. Maybe have one large plot for a developer and then acre parcels for the rest? Just a thought.

Hey..if you girls can sell it...more power to you! LOL Can I have a job as your Limo driver when you do??? LOL
