The ones that didn't want to listen (unless the noise came from their earbuds), I figured would be their customers.This is a very different time, with very different timelines.

What about noise sensors?

None of the tenants has ever said a word about noise etc.

If not, tell him you think they are acceptable, but thank you for pointing it out (no one wants their baby to be a dust bucket).Leaves in the garage, tell him it's an act of nature, he will need to remove them himself with a broom or otherwise.Neighbor complained to you about his noise, too bad so sad for the neighbor, the world does not work that way.

Dust, smells, noise, contractors in and out at all hours...you get the idea.If you're married, this is a decision you should talk over with your wife - and you should give her absolute veto power over it, with a guarantee of no hard feelings if she says no.A solid marriage is worth FAR more than any real estate deal.
