As seniors age, they often find their once-perfect homes lack the amenities they need to live comfortably and independently. At some point, they must decide whether to modify their dwelling, or move.Common home revisions include installing a stair lift or easy-use fixtures, like oversized light switches and push-button doors. Certified aging-in-place specialists know how to anticipate the needs of seniors. They can be found on the National Association of Home Builders’ website. A senior who needs only minor changes to remain in her home is likely to find renovation is a better choice. If the local real estate market is sluggish, getting a fair price for selling the home might be difficult, even with updates. Other reasons to renovate include preserving professional, social and medical connections. Moving may mean losing contact with friends, family and doctors. However, moving is better if downsizing makes sense. Once the nest is empty, a house can be too big to care for and expensive to fund. Moving might also be best if making the house safer requires major renovations. For example, is the front door located atop a full flight of stairs? Seniors who decide to stay and modify should gather as many estimates as possible. Get referrals from friends and family, and review companies online or through the Better Business Bureau.
