Just an idea I had. I've found a handful of towns that don't have websites for people to find rental properties. These towns have Facebook groups for people looking to rent, but it's not easy for them to find anything except for actually doing footwork or site-jumping to see different apartments. They are also of size that they don't use bigger sites like Trulia and Rent.com. Do you think it would be profitable to build rental listing sites for these areas? How would you go about monetizing them? Paid listings, ads, etc?
