If you've got your contractors in a row this should be a reasonably fast repair, and if the tenant objects to cooking in a microwave in the living room for a week while you get repairs done then he should consider renting his own hotel room on his own dime.

@Melissa A Cook - Good luck on your journey.

Likewise if there is something I an answer or help with let me know, I primarily focus on the Kane Co area but own a couple in McHenry, Cook and Dupage as well. 

So, if you want to go, or if you know someone that is interested, PLEASE let me know ASAP.BTW--FYI---he says she is VERY attractive and a great cook too!

My code books in storage and Cook municipalities are tough on local amendments, did the inspector state what the expected?

In my area, the smaller multi-units might have electricity and gas separate, and then you find that the gas is only used for the hot water and cooking - heating is usually central to all units in those.
