Is that residential or commercial?.
Its depends on what allowed to be build on the land. to know the price you need to know how many unit or sq and how high can you build. what about parking?
There is also improvement stuff you need to know before you going to construction. what will be the improvement you must do by law around you house or commercial building.
and don't forget to check for wet land or contaminate.
If you looking to buy land I know some expert.
