I suspect based on the neighborhood, maybe the lawns just go unwatered, and the tenants must use an automated car wash, or one of those places where you feed in quarters to get soap an water.

Have you tried rubbing bar soap along the runners?

My wife quickly realized the power of Amazon/Prime, and now we get nearly EVERYTHING that way -- from toilet paper to dog food to light bulbs to soap to birthday presents and even some food.  

We have seen it recommended that walls & ceilings be washed with special soap and/or vinegar and lemon water to kill the odor.

Majority of homebuyers want that amenity in their kitchen, although hard surfaces(quartz, marble and soap stone) are making a comeback.My rule of thumb is you to use granite in homes that are $140k & over.

One job the architect specified these little (cheap looking to me) soap dishes.

I just know so many people who don't ever check their dryer lint traps, or use too much soap, etc.

It was while I was shampooing the carpet in my socks, feeling the soap and grime ooze through my toes, that I promised myself I would never do another self-managed rental again.  

Put a key lock on one of the closet doors to store your things you don't want others to use.Have extra stocks of commonly used items like soap, shampoo, lotion.

Once I was tiling a bathtub/shower wall and I put the soap dish off-center.
