Set up an appointment with the town building department. 

It's better to sell fewer home for retail than build homes at loss.

We operate a small retail business out of commercial space in the building with the 4 residential units, which pays me a W2 salary and my wife has a part time W2 job at a vet clinic. 

Unfortunately, I don't think it's realistic that you will find a generic commercial lease online that checks all the compliance boxes for your state, city, and county.There are limited service property managers that will do retail tenant placement (rather than full property management, which it seems like would be overkill for this one commercial unit you manage), and this would be included as part of that basket of services.You could also hire a lawyer, but I think that property management company will be more cost effective. 

My favorite option for putting your own business into play is mixed-use which is retail on the bottom usually and residential on the top.

So if you buy and rent out a retail center or an apartment building or increase the existing income the property is going to be worth more and can be refinanced easier.

.- Most of the deals that came our way were for 60-70yr old wood frame buildings, that had been owned by their current owner for 25+ yrs, and we felt there was a definite risk that the economic viability of the asset was less than our planned (buy and hold) time horizon, and we were also highly skeptical of the insurability of some of these buildings or that the cost of insurance would not balloon once the ownership transition forced the insurers to reassess the building.Ultimately we pivoted to retail/light commercial mixed use properties.

Check with Cleveland’s housing department or local nonprofits for any available grant programs aimed at improving affordable housing.3.

Counties/cities building department's should have a list of registered GCs as well. 

the majority of the successful urgent cares in the county are in close proximity to grocery anchored retail centers.
