Damn, glad I don't need any new windows, knock on wood. I would say those prices are crazy, but everything is crazy.

Now for a real answer from me. In my experience home inspectors (my step dad has a home inspection business) other than noting the type of window they'll only flag if the window is cracked or can't be opened. Evidence of moisture will also be called out. Those windows look old, but don't appear to need immediate change. The door is probably the same unless that is recent damage. If she has the money though she won't regret it.

A couple people mentioned Window World. I did my last house with Window World and was very happy with the results. Thier vinyl windows were so much nicer than my old aluminum windows. I did upgrade to energy star because there was a federal tax credit at the time. Even Window World has increased their prices.

Also, don't hope a home warranty will come through if the AC leaks coolant. Just dealt with that and a swift cancel of such warranty.
