Regarding the window, I called the hardware store and found out that a window pane (even larger than the one I broke) would cost $36 to $41 depending on the quality. I figure his friend doing the work didn't charge him more than $25/hour, and that it is pretty generous to say replacing a window frame is two hours. Therefore a generous estimate is $91. I will offer this amount. Everything else is normal wear and tear. I lived in the place for 8 years. That's a lot of wear on the carpet, the walls, permanent hard water stains accumulating in the tub fixture, etc.
