Give this video a watch from the Ohio Department of Commerce Division of Real Estate.

@Christopher Phillips I completely agree, if the only reason you are getting your license is for MLS access, it will cost you dearly.

You can find out whats allowed on an industrial zoning by visiting your local planning/building department either online or in person.

Right now you are in the getting taken advantage department.  

I have a kid who's interested in real estate and he got a job working in the closing department at a large lender. 

We had no fire damage or even threat of it, as we are over 30 feet away, catty-cornered, upwind of the fire. extreme negligence of the Fire Department and operator using heavy equipment on a personal residence. 

Usually, first step is to speak with the local planning and building department about rezoning.Then you have to check their requirements and if you need a variance.

I believe parkland is in pierce county and they do,have a department that deals with these types of things. 

Definitely talk to a few bank's lending department to see what their requirements are.

@Andra Tom your first step is going to be to go to your local building department and make sure that the current zoning still allows for your house to be used as a two family.
