I'm not really sure where best to put this query, hopefully it makes sense being here!
Basically, we are hoping to go and view a property at the weekend near pwhelli, north wales which comes with an acre but there is the option to purchase 17 additional acres. Now the estate agents have been really cagey about the status of the additional 17 acres, it took several e-mails back and forth to even establish that the land was for sale and not just for rent. Anyway, the asking price is 150k and the estate agents have said that we would need to adjust our offer depending on the amount of land we wanted to include with the sale of the property.
The problem we have now is that we have no idea how much we should be offering on top of the asking price for each additional acre we want. The land is rough grazing, a few trees dotted around. Some of it is also sand dunes, so not very productive but right on the beach. Is there somewhere I can look to find out how much land like this is worth in that area or would we need to ask around locally?
