Looking to invest in Ohio and would like to get market feedback

[Henry Der]

Hi, I am looking at investing in Ohio, single family home rentals.  In particular, the area of Lima and its surrounding area.  One scenario floated across to me are homes in the 25-30K range with rentals around 300-400.  Is this a norm there?  Also, can anyone share about the 

1. is Ohio a good place to invest
2. economy
3. major industries
4. demograhpics
5. tenancy act if landlord or tenant biased
6. quality of renters that are paying in this range
7. difficulties in holding a large number of these (100+ homes)

Thanks very much!
