Slap a silencer on and it’ll be just fine.
Even most stealth games allow you to pop two heads at once if you’re fast enough the second guy can’t yell.
I’m a big fan of Watch Dogs and Cyberpunk style stealth hacking though. Jump into the security cam network and kill everyone in the building using environmental hazards (and in Cyberpunk, spontaneous combustion and other fun tricks) while you sit comfy a block away. Real fun to still get the stealth mission objectives popping up after when you walk in like you own the place. Or when the game still has pre-scripted dialog about how tight security is while I’m walking through a pile of their corpses.
Plenty of other great advice. Just tossing in: I would kill to have regularly available reliable childcare outside of my working hours so I could take care of my living space better.
Moving out would complicate that for you.
