Don't make any improvements is a crazy proposition. But I agree with living in the place 6 months before doing anything drastic unless it is obvious. I live in a very old house. It took us a while to see the reasoning behind some of the features in our house. We were tempted to scrap anything that wasn't typical in new constructions, but that would have been a waste of money.
I was happy saving up for a few months and observing the house to see where my money was best spent.
It's meant to stop you from spending $30k on a kitchen renovation because you hate the way the cabinet doors open, not to fix health and safety issues.
