I would print this out and give it to the tenant: https://www.countryliving.com/uk/homes-interiors/interiors/news/a1511/how-get-rid-of-moths/I've never known anyone who had a moth issue in their house so I did some research and I would tell the renters to keep their food in plastic containers/the fridge and make certain there isn't any open food/crumbs in the pantry. 

Lo and behold, their young kids had flushed some small plastic toys down a toilet and they caused an obstruction that led to continual clogs.

I got a short typed paragraph from a medical professional stating "It is my clinical judgement that this individual would benefit from the allowance of a pet companion at the residence."  

A pet doesn't need to be a trained service animal, many are therapy/companion animals.

Real estate is not going anywhere, nor is it the only game in town.Next time you go to the home improvement store, look for the plastic drain snake you can buy for $2-$3.

Plaster and drywall count as noncombustible, but a plastic dishwasher drain pipe doesn't.If there's a basement, or even a crawl space, under this kitchen, you might consider running a new water supply pipe and drain pipe down there. 

It seems like the new thing is to put a piece of plastic on it and call it stain blocker.

I'm not as concerned about the cracker plants themselves (although that will bring jobs and housing demand) - but I'm looking at the bigger picture of petrochemical and plastics manufacturing, particularly up the 376 corridor towards New Castle/Sharon.

Those nails (about 1 1/4'' long with the plastic washers on them4.

If you know what features each offers, and the price points for that particular manufacturer you can make an intelligent decision as to what items you want to buy.Or, if you don't want to go to the trouble of learning all of these things, you could just go the "get the cheapest" rout and roll the dice and take your chances, but if you make a mistake and you have 100+ faucets to replace after only a few months because you gambled wrong (or 100+ toilets with plastic flush levers that break off or won't flush much volume, or etc...) you'll probably wish you had more knowledge of these things before cutting checks.Good Luck!
