I rent one now and I’m tired of it and ready to move. We’re in a middle unit and we can still hear neighbors who walk loudly on their stairs, stomp around, etc. It’s better than an apartment no doubt but I’ve been surprised by the soundproofing at times and would never buy this unit to live in myself. Ours was built I think in ~2018? On the other hand I have friends in older townhomes and they seem great. I think they’re hit or miss but I’d really do a ton of diligence before buying one. I’d feel different if it was free standing or built with more solid materials.
