Looking For Reputable Property Managers

[Dan Shelhamer]

I am currently self managing my properties, but as I scale, I know that won't be a possibility at some point.  Does anyone have any recommendations on property management companies in the Northern Suburbs of Illinois (Lake County)?  I would like to start speaking with a few of them and seeing how they operate. 

Also, for those that use PM's, what are some good questions to ask when interviewing them? 

Thanks in advance!
