The zip codes for these areas are 21040, 21001, 21903, 21901, and 21921.

As I understand it, the price of each lead is based on zip code and determined by investor demand. 

43560, 43623, 43612, 43613What class category would you consider properties in those zip codes to fall under?

Yes, lower criteria opens you up to potentially worse tenants, which could lead to many issues (non-payment, evictions, property damage, poor maintenance, neighbor issues, etc.). 5) You could really get into the zip codes, but just as a very high level tip, you could focus more on the West side, or North West.

City of Cleveland is cracking down on this and other requirements to include lead safe certification and status certification by zip code at varying calendar dates.
