C1 may allow a property to be used as a day care, restaurant, bank, florist shop, bed and breakfast etc. but NO multifamily. 

I am now up to eight single family homes and I am trying to define my strategy going forward.I have been shopping single family and with higher prices, it is getting harder to find a good cash flow.

I have brokered a few multis in Portland in my day  an 80 unit  and a hand full of smaller one's over the years.. but its not my main gig by any means.. you will want your POF  all lined upand your financing.. as well before you go shopping you won't get far with out those things up front.

Shop around with different banks. 

There will only be a few brokerage shops that specialize in this...for example, Dallas is a huge market for multifamily but there are only about a dozen or less brokerage houses there that sell large multifamily, and out of that dozen, there are probably 3-5 of them that sell the majority of the product.I'll warn you, this isn't easy and it's a relationship business. 

It took me some shopping around find a broker who knew how to get it done.

Where the general population shops is retail.

It is close to the University of Louisville and to the airport, but there are nicer neighborhoods that are also close that have more restaurants, coffee shops, etc. to offer an out of town visitor. 

Maybe it would make sense to buy a shopping center and move your business into the center.
