When you eventually get to windows consider triple glazed. In a city the noise reduction is worth it alone. I put some in the current house and never regretted it. Back then it was only available in fixed windows. We live on a rural two lane highway and you cannot even hear the cars go by. Not that traffic is heavy along here.

Windows have high margins so usually you can work a deal. Locally the thermo units have gone to a thirty year warranty.

Triple glazed is steadily gaining so perhaps by the time you are ready it will be more conventional. Fifteen inches of insulation in the attic is a good ideal when using heating and air conditioning.

That means about eighteen inches if blown in as it settles with time. . An easy job usually your kids can do if you are unable. Not really too expensive with the loaner machines and a big bang for the buck. A poorly insulated attic is common in older houses and the cheapest improvement possible probably in a lot of cases. If you have any soffit roof venting do not obstruct it though. Many older houses had little if any to start with.
