It's unfortunate we have to be concerned about the long term health of IL.Like the other posters said, if you can get out and not have to take a huge hit on tax implications and closing costs AND be a lot happier about your investments... then pull the trigger.  

Good health...at this stage of our lives nothing else matters !!!

A good way to cut through some of that volatility and get a better picture of the health of the housing market is to look at a 12-month moving average, which shows sales are currently at the fastest pace since 2007 despite recent declines.

The local Department of Health and Environmental Control can usually provide guidance relative to which contaminants, if any, are prevalent in your project area.

Here is where my dilemma comes in:  I could be getting between $500 to $700 more a month for the rental if I went with market averages.   

Has the tenant provided documentation from her health care provider?

You will still need to find the local code for minimum lot size, and if it is well and septic sort that out with board of health etc. 

Unfortunately this now sets a precedent that the CDC can ban evictions whenever they want, if in the interest of public health.

Very short story, I want to purchase a home from a family member with failing health by the end of next month.

@Justin Tomsic My wife and I had a very similar sell/keep as a rental dilemma.
