I can't use the income approach, its a small town with maybe 3 restaurants or so, comps are nonexistent (I think) and its been vacant for a few years now.According to the assessor the land and building value is $50,500 (I'm using that as a ball park number) although the current owner did pay 300,000 for it previously.

With this approach it is very important to set a before rehab price that leaves room for added value.
