locating distressed properties

hey guys i have a question me and my partner are wholesaling in the san diego area, we are running into a road block because the problem is we are having a hard time locating properties that arent under realtors. of course we dont want realtor listed properties because we cant get them below market value because then the realtor wont make his commission. we drive around daily and look in the papers is their any other method that you guys would recommend for locating properties. all suggesstions welcome thanks guy i appreciate it
