My rent went up a lot

My rent usually goes up a little every year. This year it went up a lot. At first I was wondering why so I asked my resident manager. It's because our building finally got out replacement windows. Part of the reason is for energy efficiency. They say these windows "leak" air less so we use less heat in the winter. They come with a lifetime warranty so we should be good with windows until I move. The new windows will also increase the value of the building that I live in. I don't like that so much.

I'm all for them increasing their property value but I need watch in case they may try to sell the building. That would seriously suck.
