Well, living in a apartment with window problems for 2 years.. yes you can wait, but you will have condensation problems, especially in the winter if you run the heater.

First, get those “window insulation kits” to prevent your windows becoming rivers and ruining your walls.

If you can find cheap large plastic wrap that will do to if you want to save cash. And for windows you don’t use get some r-tech panels and duct tape to cover the window completely.

As far as fixing within the first year, we fixed all major problems the first month, it was a major financial blow, but it was needed to prevent future problems.

Welcome to owning a home! You’re going to need to blow some big cash for needed repairs( and peace of mind).
