I'm thinking about buying a house right next to some railroad tracks mainly because it's one of the few affordable options that will allow me to be close to my grandson. The home has some updates already started, and right now, there's a lack of drywall in many areas. I definitely need to soundproof the walls since the trains will likely be loud, but I want to do it on a budget. I'll already be spending on replacing windows and the roof, which is currently metal. Should I just repair the metal roof or switch to shingles? Also, I'm open to any DIY-friendly advice, especially regarding windows since I'd prefer something that's not too labor-intensive. By the way, this home is quite large at 4200 sq ft, and it could revert back to being a duplex. I'll probably focus on one floor before tackling the other.

Keep the metal roof unless it’s severely damaged! Replacing it with shingles could be risky, especially in hail-prone areas. And really, once you've got the drywall out, rockwool is a great choice. Drywall is okay, and while paneling is easier for DIY, it can hurt your resale value later. Quality windows are key based on your local climate too; higher-grade ones can really help soundproofing and keep temperatures stable.
Honestly, you might get used to the noise after a few months. Your brain adapts surprisingly well! But if you want serious soundproofing, I recommend using rockwool insulation, resilient channels, and double layers of 5/8 inch drywall. For windows, triple pane would be ideal. Just keep in mind that a lot of the low-frequency noise from trains comes up through the ground, so it’s tough to eliminate completely.
No way, I’ve been living next to trains for five years, and it’s still just as loud as day one!
For the best sound reduction, definitely go with triple pane windows and fill the wall cavities with rock wool. Then hang 5/8 inch wallboard on resilient channels. It’s a solid setup for minimizing noise.

True, but it all depends if you're near freight or commuter trains. Commuter trains can be quieter, but freight trains can rattle your whole house. I know from experience!
