And they told us we wouldn't see another crisis in our lifetimes.But that toothpaste tube can only be squeezed so hard. 

Who keeps leaving toothpaste all over the bathroom counter?

I have done this many years ago, and there were problems; like some things were missing from my room, someone eat my cheese, toilet seat was left up, who used my tooth paste ----- they are playing their radio too late, strangers entering the building.Sure you can increase your income - but not worth the problems - you just maybe want to get better at making offers on properties you can control at wholesale prices.

I would wait for 2-3 months before making the purchase so you can use the renters money to pay for the entire shipment and analyze their spending trends and see what items they enjoy the most and best prices that would out compete those places. convenience things like toilet paper, tooth paste, tooth brushes, laundry detergent, soap, bounce could be an option, and then you have snacks, cold drinks, phone chargers, etc.

First--do you supply all of their items like shampoo/conditioner, toothpaste, laundry detergent, etc.?  

He buys things like toilet paper and toothpaste in bulk, one year supply at a time

Did you forget to put the cap back on the toothpaste ? 

Tenants are notorious for pulling out the pop up stopper and dropping toothbrushes, hair, toothpaste caps, etc down the drain.Glacier Bay is basically a lower quality Delta.

Us short people are not at risk here, but I have seen way too many ceiling fans that are at about 6'6" that someone installed without thinking.Construction adhesive does not take the place of nails, for most purposes.Don't wire 3 way light circuits to break the ground, leaving a constant hot to the light .Some cheapskate figured out that toothpaste makes a great filler for nail holes before touchups.

Some of these states will have a hard time putting the toothpaste back in the tube any time soon.
