Hadrian X, page-104

In the first phase of adoption the property market is almost irrelevant. The savings will drive demand, and they won't be able to produce enough to satisfy demand immediately, even in a slow market. So the early adopters will make good money, and won't pass on all the savings to the end user as they will be able to keep good margins given they will continue to initially compete against those who necessarily need to keep using manual labour.
Once in more common usage, margins for operators will drop as they will then be competing against each other. At that point, more savings are passed on to the end user.

Once there is broad adoption, then property markets become relevant as total demand will be dependent upon market activity.

So the only primary risk I see is whether it works to spec. Secondary risk is competition, but they seem safely ahead of the pack.
