I've been thinking along the same lines, looking at properties that could work. Ultimately, I foresee one major problem -- their bandwidth, servers, food, electricity, water, heat, etc. will cost you hard cash, while they live rent-free, with no incentive to change the status quo. My alternative would be to charge rent... to their investors. I envision a group of investors to whom the tenants would apply. Investors pay rent to you on behalf of the entrepreneur(s) of their choice. As long as they keep the investors happy, they stay at your place, and you have the financial means to make it work. I've identified multiple sites at which this plan could work, but would need an investor of my own to quit my day job, move into a site, and get it ready.
