I have a flip in Southside Chicago that just has a minor punch list that needs to be completed. We already have a buyer who came in at ask. The thing is, our house is being targeted for vandalism. We've had a fire set to the garage and on a separate occasion, a window broken. These incidents are within a week of each other after we accepted the offer. One was at night and the other in broad daylight. This isn't an overly crime-ridden neighborhood but I'm afraid that we took a vacant hang out spot away, so there may be retaliation in that regard. We found kids hanging around the property smoking weed on a couple of occasions but felt it to be harmless. We have a house sitter at night, neighbors are very active in the neighborhood and try to call the police, but what else can we do?
