Next, up to about 200 spaces, typically will have better locations, more amenities, municipal utilities, fewer management (read "tenant") issues, and will be priced in the $4 - $9 Million range.  

Much of the industry is about 3 or fewer years old as well and there hasn't been enough time for any sort of standardized market to form.  

I don't think most real estate investors would be willing to go in and do what you are doing (since you said you don't mind living in a "dangerous" neighborhood), and therefore the competition for these properties is much less despite likely future appreciation.I don't see why you shouldn't rent it as long as you screen your tenants well... although I'll admit I don't know anything about that process.

In other words… if I would like to rent to nurses only, would I be putting myself in potential legal danger?

the fewer contingencies you have, the stronger your offer is,  but the more risk you have.I like to have an inspection contingency, so I can get my contractor in to look the place over and let me know how much it will cost to fix (my contractor is also an inspector).  

I've read that owner financing could be dangerous when the owner still has a mortgage but am unsure of a different way to structure this without getting bank financing involved.
