According to the latest Housing Market Index (HMI) from the National Association of Home Builders (NAHB) builders are more positive toward the 55+ single family market. The HMI for 2Q 2016 was 57, making it the ninth consecutive month above 50 (which indicates good conditions from builders).
In an article for The MReport, Brian Honey reports on the results of the survey which ask builders about such things as prospective buyer traffic. The results of the NAHB survey were similar to that of a July survey by Freddie Mac:
...which found that many 55+ homeowners are going against conventional wisdom by working until a later age, aging in place, or buying a second or even a third home rather than selling their homes to Gen Xers, downsizing, renting, or moving to an age-specific community.
