I would contact large companies, hospital, HR departments to start with if you haven't already. My market is limited as the town is not that big. One company had overseas executives coming for a month or serveral weeks at a time to look over the company they bought - that company used a couple of model homes. Another 2 large companies in our town already had corporate homes that they owned for that specfic purpose. I believe there's a market for corporate short-term rentals, but depending on the size of your town it may be more limited that the general rental market.
