Graham, The real question is how you bought the unit. You state that you bought the unit through a foreclosure company, but the question is did they provide you with a quit claim deed? If so then you may be responsible for all outstanding assessments. However if you purchased the unit at a judicial foreclosure sale, or you received title to the unit via deed in lieu of foreclosure or took possession pursuant to a court order under Illinois Mortgage Foreclosure Law, you shall have the duty to pay the unit's proportionate share of the common expenses for the unit assessed from and after the first day of the month after the date of the judicial foreclosure sale. Also what did your contract to purchase state? We have a phenomenal Condo Training Program at the Chicago Association of REALTORS in conjunction with Lakeside Community Development Corporation. Any condo owner and REALTOR should attend as condos have their own rules and regulations. Web Reference: http://www.chicagorealtor.com/displaycommon.cfm?an=1&am...
