Make sure it isn't in a flood plain or flood way.Do your research to make sure there is value to and end buyer.Also do a title search before you buy it to make sure there are no issues that you can't easily clear up.

2 things by using a space heater the regular thermostat is not registering the proper temp in a room,, or by using the stove,, the stove is a fire hazard and by no means should be used for heating.. who's paying for the fuel to heat or run the stove.. just plain wasted energyGet rid of her, let her out of lease all, she's accident waiting to happen and write her up for not properly using appliances,, NO space heater should be used in your lease,, that alone unattended is a fire hazard.You will never satisfy her

Here's why:Aluminum windows last the longest.Tempered or laminated glass are both stronger than plain annealed glass (laminated is just a tick more energy efficient).MUCH cheaper than good quality custom sized impact windows both in initial cost and replacement cost (I doubt that you will find exact fit factory replacements)Covering them with a permanent, crystal clear, UV filtering shutter will prolong the life of the window, eliminate water leaks and window maintenance.Permanent shutters don't break so there's no replacement cost and offer continuous protection whether you're home or away.Increases home resale valueIf you simply want to flip the place, go to a cheap PVC impact window supplier and get a list of standard sizes and modify your openings to fit.
