If you go to the website below, click the map search and then advanced search you can view all vacant land for sale in Brighton or surrounding areas.
In general, the more improved a property, the more it's worth, so I cannot give you a specific value.
If you write Tim Sova firstname.lastname@example.org he can email a more accurate price range based upon your needs.
I hope this helps,
