The absolute best way to age in place is to already live in a home that maximizes function (without looking institutional). Even with access to any of the helpful programs listed in the article, households are likely looking at a period of unnecessary hardship, cramped lifestyle, expense, and danger before and during almost any remodeling effort.
Alternatively, we promote the culture change where people plan for their housing futures the way many of us plan for our financial futures. We’d also much prefer an “age-in-community” model where housing options exist to provide choices and people are much clearer about 1. how much a home remodel might cost (a lot), 2. how much functional improvement is possible (often not nearly enough), and 3. if their current neighborhood and community really works for them any longer (friends have moved on, driving is the only way to get around). Plan ahead!
