How can I get over my hesitance putting in offers?

[Gino Tomba]

Hi BP,

I have studied Cleveland-neighborhood-grades for awhile now, but I am still not feeling confident understanding what I could get for rent in certain areas with a duplex.

My original search was based solely in Lakewood and I was confident I knew how much I could get for rent in regard to area/condition because I have a close friend with a few under his belt there, but I have now expanded my search as far west as the Lakewood border down to north of Middleburg Heights. 

I understand checking out Zillow, Hotpads, etc., but I am becoming hesitant putting in offers in areas like Brooklyn/Old Brooklyn/Parma/Parma Heights/Puritas/Detroit Shoreway/Kamms Corner because I just don't have as much of a connection and I feel those areas are not as sought after as the more hip North of route-90 areas.

Advice? Or a better resource for info?

Thank you everyone!
