I have yet to use forceful or harsh language besides saying initially that no providing of leases is unacceptable.

I wouldn't have put it so harshly, but I have to agree with the sentiment.

Steven Taylor I never, ever let tenants do pool care; chemicals not right, damage pool finish etc.... take care of it professionally People share pools all the time in apartment communities, so I don't see a reason why it can't be for both houses.

Sounds pretty harsh right?................

Since it is in a solid area it will be easy to re rent to a quality tenant unless you are truly terrible at tenant screening.Sorry to be harsh.

A little harsh if you ask me.

Told him I would help him fix the issue and educated him that mice, unlike roaches and bed bugs, aren't treated with sprays and other chemicals.

Chemical warfare.Biological warfare, folks will go to an infected tree, beetles, worms, fungus and collect the stuff and plant it on the target.

Best of all, we have a great plumber, Bob.We do not allow chemical drain cleaning products to be used in our plumbing systems and we cover that in our rental agreement.  

Unlike the regular "drying" compound, this stuff chemically reacts and "sets".
