Currently, the tenants are not aware that they are living in a toxic environment (1st floor unit only).

It came back will high toxic black mold and we could not say anything to the tenants about it. 

When I brought it up to the management company (who was aware that he had moved in), they put him on the lease, but I'm irritated that I had to ask.

Not a super great thing and now I remember why I let my membership expire, it was the irritation at not being able to search for current listings.

That irritates the seller and they often will drop that agent.

Most the listing agent around here all they do is put the house on a bunch of sites including their own to look busy, have irritating auto emailing and voice mail for potential buyers.

Most likely, I'll just disappear once I realize I can't get rich overnight, leaving you exhausted and irritated.

If rash, irritation, redness, or swelling develops, discontinue reading. 

@Mark Whittlesey Good to hear that I'm not the only one that gets irritated by this!

Burning wood in a wood fireplace or wood stove... great amounts of burning means the chimney needs to be cleaned more often, sometimes tenants will burn paper and plastics releasing burning embers that fly out and/or toxic gases.4.
