A friend of mine lives in a high rise close to Little Italy. The condo next door was being rented by the day, mostly weekends. One night two couples entered his place at 2am carring beer cases. After some shouting, it was clear that the couples could enter the wrong condo because the developer never changed the door locks. All condo doors could be opened with the same key. Today that condo next door is in foreclosure as is the identical 700 s/f studio unit above my friend’s place. My friend bought in 2005 for 460K, the foreclosed unit above is going for $250K.
