If you are doing the improvements for your own quality of life, by all means go for it and enjoy it.
I would suggest checking with a local Realtor what the improvements are likely to do to help your particular home's value. Update to the kitchen and Master are always good investments in my oppinion, especially if you are going to enjoy it and then sell before it's outdated again.
You should also go to some open houses of new construction homes to see the most recent trends in finish work, etc. That will help you get an idea of what you might like to do, AND what other's are buying (resale value addressed). Anything you do above and beyond the recent trends will likely not add value, but should help you sell faster when the time comes.
My mother grew up in Genoa, Ohio and we love those Mud Hen games... who wouldn't want a house with a new bed and bath close to the Mud Hens.
Im updating some of our Trulia information and found this post from a couple of years back, if you would like a recent market analysis on your home let us know :) Currently listing inventory is very low compared to previous years/months etc.. Michael is dealing with clients that are having trouble locating a home in your price range that is move in ready, updated etc... keep this in mind if moving is still something you are considering. Best of luck! and let us know if we can assist.
