If you have a specific area that you are interested in, I would suggest buy now, hire a property manager, and rent until you get ready to move. Do a search on this site for renter/renting (and variations) and you will find additional background information.
I have not seen any announcements with regard to additional homes in the immediate area to the existing villages. There are new homes going up in the village of fenny, about 4-5 miles (by car only) to Brownwood, and there are rumors of additional land purchased in the area of the turnpike for possible expansion. Since you have already visited, you have an idea of the lay of the land and probably some idea what you want, so keep an eye on the new and for sale to see if you find what you are interested in. Who knows, you may retire early, and then you could be all set.
