I moved out of a slum apartment that I had been in for six years, paying high rent. When I first moved in, it was worth what I paid. It was in a nice neighborhood and was actually a very nice apartment before this slum lord took over. I held onto the rent, hoping he would repair things that needed repaired (like the toilet water from the bathroom leaking all over the stove in the kitchen). He eventually got things fixed, but only after several attempts.
