Thinking of building adult condominium on Black Creek waterway to Lake Erie in Port Dover viable price range?

There will be 4 units aproximately 1300 sq. feet, with 30' each dockage space for boats. Great view of Port Dover yaght Club across the river. 2 bedrooms, living, dining, 1 1/2 baths 2 story, plus garage, loft type Master bedroom overlooking the beautiful waterway, as well as a great deck, a lovely park like common area around the boat docks. 1 1/2 hrs from Toronto, London or 3/4 hr from Hamilton! Amazing nature around, Blue Herons, many species of ducks. Lake Erie is great fishing, boating, swimming. Great ice skating, cross country skiing and snowmobile trails in the winter! Much more going for us here in Port Dover.....too much to list. Just trying to get an idea of a selling price?
