How to Determine Market Rent

[Michael Lamb]

I am looking at purchasing a duplex in Twinsburg, OH, as a primary residence.  I plan on living in one side while renting the other side, so I can take advantage of putting 5% down.  My goal is to move out after a year and be able to cash flow once both sides are rented.  My problem is being able to determine what I will be able to rent each side of the duplex for.  

I can't find comps in the area to get a good feel for rental rates. I have a Rentometer account, but it isn't pulling good comps either. I am new to REI, so I don't have a good agent to get numbers from and I don't have any Property Management contacts to talk to.

Does anyone know where I can go, to get a feel for what I could rent a (3) bed, (1-1/2) bath, 1,200 sqft duplex in Twinsburg, OH for?

I appreciate any guidance you could provide.
