Have a clause in your lease that landlord is NOT responsible for battery issues - tenant is.

Don't grill me too hard.I own three rental properties, one is my primary residence with an apartment (5 units total between 3 properties: 1 airbnb, 2 medium term healthcare leases, and 2 long-term rentals).

We’re experiencing the same for our unit on a 6 month lease and suspect it’s due to the time of the year.

What's the best way to navigate this situation regarding the application process as well as the lease administration?

We then leased the home out to a long-term resident who signed a multi-year lease.

Yes, long-term rental clients sometimes don't want short-term rental next door to them, but you are the owner and landlord and set those expectations up front so it's on the table before they lease.

But once I got the bills, I increased the rent with the tenant's approval and signed an addendum to the lease stating the rent increase would be X and the owner would take over utilities.

Plus when the lease is up they tend to move to another updated apt.  

Cleaner took pictures of the condition she found it, then after cleaning.

Personally, I wouldn't offer SubTo or a Wrap, For reasons I've written about fairly extensively. https://www.biggerpockets.com/forums/70/topics/1227199-the-m...However, I would sell on "Lease Option" and that may work for you.
