Hi - I have friends who live in Johnsonville and their kids go to Hoosic Valley - what a great place to live!
Of course the big question is, would you like to have a garage? I always tell people who are thinking of making some changes to a home but plan on staying there for a while before putting it on the market - will you get value from the change before you sell?
I would be more then happy to show you a comparison of properties that have sold recently in the area with and without garages so we can ascertain how much adding a garage would add as far as value. However, I know there are a lot of people in that area that have "big boy toys" such as snowmobiles and off road motorcycles/atvs. They might appreciate having a place to store them.
I work in Rensselaer county, and I also live here, and I know your area well. Please contact me offline about the research.
