If it's on the main street there's a slight chance of getting something like an AutoZone or Dollar General or some other national retailer. Those large national retailers typically work with a group of developers who will build stores for them based on a guaranteed build to suit lease. I.e. if the developer builds them a store to their specifications, they will agree up-front to rent it for 10, 15, 20 years. The developer can get bank financing based on that because they know that it will cost them say $700k to build it but they can sell it to an investor for maybe a million who then gets a nice steady rent check every month for the rest of the lease term.
A lot that size might be worth a few dollars per square foot. Say $100-150k. Even if the city threw the land in for free that's not worth that much if you're talking 10-15 units, basically saving $10k a piece on something that will probably cost $100-150k a unit to build. The best bet is a local homebuilder who wants to take on a larger project. I can't see many developers from larger cities going into such a small market where they don't know the nuances of the zoning, don't know the market, don't know the demand, etc.
