Selling 2 Duplexes in Minneapolis how do we determine a good deal

[Blake Wash]

Hi, We are in the process of selling two of our duplex properties in Minneapolis. Are there certain measurements or (industry rules) we can use to determine the minimum price we should list our properties to ensure that we receive "X" amount in return? 1% or 2% (troubled war zone) I understand many variables may impact this outcome. However, we were curious if there was a minimum % you should expect as a return. We have owned the properties for about 3 years now with a comfortable appreciation value but the tenants are a headache.
