The usage of the two machines matched 100%.I just emptied out month 2's bins, and found that the coins in the washer represented only 1/10 of the usage of what was found in the dryer. 

@Ryan Duphorn  a  5 /2  and 1920 square feet IMHO isn't a good health care traveler accommodation unless you are in a area with a shortage of housing. 

Wait… I thought they already were the Amazon of travel—minus the free two-day shipping vacations!

Just to clarify your water usage hasn't likely gone up 20%, but rather the amount tracked amount they are billing you for. 

I find that internet providers, like Comcast, tend to update their technology and offerings to better speeds as customers have higher usage demands.

Following the installation of a new water meter, I received a true-up for the previous underbilling.Since the meter replacement, my water usage has increased by approximately 20%, and I am now receiving monthly bills instead of the previous bi-monthly statements.

It is common and customary acrossa almost all rentals except some A class office to pay your share of utilities.Now you can make whatever arangment you'd like and work it out however you want with your tenant but if you are going to "share costs" I'd suggest keeping the utilities in your name, and then "back billing" the tenants for that share of their usage, but again thats a lot of work for really no gain in my book.My recommendation would be to simply have the tenants pay all utilities. 

When I asked why I was paying for a service fee during a period where I never turned on service, the customer service person explained that even if I didn't have service turned on, and there was no usage, there is a monthly fee for the line that runs from the street to my house so that when I reconnect, they don't have to rip up the ground and put in a new line.To me this sounded ridiculous and the power and gas companies are not charging any such fees. 

My suggestion would be to cap your utilities at a certain amount and have Tenants pay anything over that amount.That will help you manage your expenses, and also allow Tenants to gage their usage each month, and make adjustments if they don't want to go over the allotted amount.As far as collection, provide the bill showing any overages and just have them pay for it along with their rent. 

I will be renting ADU fulltime and will not use for personal usage.
