This unit sold 10/01/2008 for $263,368 to give you an idea of how far the market has fallen but then the bank foreclosed on 09/01/2009 for $80,000.00 and resold the unit to an investor for $85,000.00 on 06/01/2010.
The investor then listed the unit for lease at a price of $1,095.00 and it was leased in 25 days on 03/01/2011 for the original rental price. He then listed if for sale with tenant for $139,000.00 on 05/13/2011 hoping to "flip" the rental property but is not currently under contract and still waiting for a buyer.
Based on the history the odds of your offer of $45K being accepted are slim to none. Property values have fallen back to 1999 price levels in some parts of town but this is not Detroit so getting what used to be a $260K unit for $130K is reasonable and doable; getting a $260K unit for $45K is not unless the unit has been gutted for some reason. There are gutted units that can be purchased for less then $50K but you need to completely rebuild the unit to purchase at that price.
