I collected cleaning fees at the beginning of the tenancy ($350-$500, non-refundable, one time fee, I just asked tenants to broom clean at move out and sent in a professional cleaning service at move out).

We have a good cleaning person for each house and of course, we use airbnb, vrbo, and tripadvisor.

I own 4 of them now in Big Bear LakeBest 3 things:They make a ton of money and are booked at almost 100% occupancy all year.The real estate isn't that expensive although that is quickly changingThe city ordinances aren't as strict as Palm SpringsWorst 3 things:Very difficult to find reliable vendors, mainly cleaning serviceLocal crime is very high11% transient rental tax on gross incomeIf I could start over I'd still invest there, it has made a great investment so far, but it has been very stressful.

I figure I would deep clean, repaint and run a hepa filter during this time.

I have good resources for a lot of Airbnb related expenses (Furnishing, cleaning, handyman, etc).  

Seems like everything has been related to the operation, check in, check out, rates, cleaning, and their fee, but not specifically about their contract.

If you aren’t able to communicate that the owner still gets paid, the property is cared for and cleaned really well constantly, and you’re actually adding a lot of value to the property because of the new rental history, then you probably need to keep educating yourself until you that message becomes clear.

Prepare the sub floor, float low spots, sand down high spots, take your time with the install, verify edges aren't damaged, maintain a clean working area, inspect and clean the channels before installing each plank, ensure a complete lock and verify seams are running square/even.

I reviewed a lease from a fellow investor and noted that he charged a $100 fee for cleaning prior to the tenant moving in.

To “clean” out the house.
