For some reason I am thinking this could unlock assets that aren't currently being used because the owner isn't as motivated by monthly rent. But might be more motivated by a more altruistic / help / mentor mentality of spurring economic growth in their home town. But you very well could be right. We'd like to test and see how small that universe is.
I certainly could be wrong. As you say, you won't know without trying.
The geography is going to play a big part, too. The average landlord in SF is going to understand startup economics much more than, say, in Texas or Michigan.
