The truth is that there are many spaces like you describd. Traffic count and the type of living space you are looking for will make a huge difference in your search. I have owned several restaurants with living space and I just placed a client in a deli with an apartment above on the coast. If you provide more detail, I might be able to suggest something.
There are options for commercial/living space or you could choose to have separate spaces. Please give us a call for some specifics. I have one place in mind that is not on the market at this tme, but could be. May be over $400,000 for ground floor commercial space and some apartments. Is this in your range?
