Old, but still quite useful

Growing old is like wine, as the saying goes, because people get better with age.

Just like wine, real estate not only gets better, but sometimes more valuable, too. Like Hudson Manor on Tampa's Davis Islands, a 66-bed boutique assisted-living facility that sold in February for $6.3 million.

Assisted-living facilities are pretty popular in real estate these days. But it's unlikely many come in the form of Hudson Manor, a facility not only minutes from Tampa General Hospital, but also in a building older than many of its residents.
