However, these short term benefits are also laced with words of caution in the long term. In the long term, there is a very real concern about a potential oversupply of housing in the market. This oversupply is likely to be caused by the differences between millennials and baby boomers. The same barriers of entry that prevent millennials from becoming homeowners currently could very likely continue to exist, as financial capacity may still be an issue for a generation growing up post-Great Recession and facing heavy financial burdens. There is also the issue of a lack of demand for the particular homes that will be entering the market in the coming decades. The needs and desires of millennials are different than that of previous generations, and while McMansions in exurbs were particularly appealing to baby boomers, they do not align with the preferences and demands of millenials that prefer being significantly closer to urban areas. There are also other factors, such as the size of homes and the design of the home itself, that will influence whether millennials will even be interested in purchasing homes in certain areas where baby boomers will inevitably be selling.
This uncertainty leaves economists concerned: another housing crash. The concern lies in the fact that there will likely be a large oversupply in certain areas, which will cause housing prices to plummet, thus leading to a housing crash in those areas
