With an ever aging population, I think that we will start to see more homes renovated with handicap-accessible features as well as more builders integrating them into new construction homes. Anytime that you are contemplating to renovate or make changes/additions to a home, your first question should be: Am I doing this to suit my needs, taste & life style today or am I doing this to potentially add greater value to my home possibly down the road? I believe that most people would answer the former. Either way, do not expect a dollar for dollar return on the investment. Although the pool of potential buyers will likely be much smaller, those who specifically seek out handicap-accessible features will likely be limited in their choices and thus more motivated to purchase a home already equipped to meet their needs.
