@Rachel1802,
More detail is needed to help assess a proper pay amount for you. How large is the area that you have to mow? Is the area flat, or are there slopes or other items that you have to make special effort or take into consideration when mowing? How much time and resources (fuel, oil, weeding line, etc.) does it take for you to complete the mowing? How frequently are you expected to mow? How many months of the year will the lawn need to be mowed? What are you property management duties supposed to entail? How often will you have to perform them?
Most of our bookings are long-term stays. My neighbor is my property manager, but we manage the listing information on all platforms, calendars, guest relations, finances, and supply purchases. He is responsible to make sure that the trash bin placed at the curb every Wednesday for garbage pick up (if the guest doesn't do it), coordinates getting the lawn mowed (this is needed only during any periods we are not onsite between mid-Spring to mid-Fall), and be the guests' point of contact for things that need personal attention (e.g., the batteries on the smart door lock needed to be replaced during the previous guest's stay). Since our regular cleaner has recently become unavailable, he's taken on the responsibility of cleaning and turning over the space. We pay him $120 to clean a 700 s.f. apartment (we provide all of the cleaning supplies and appliances), $30 monthly to keep watch on our place (we also have security cameras and a Ring doorbell), and $50 for each lawn mowing with our mower and trimmer. Today we had a guest check-in, and we paid him $200.
Typically, guests may only see him if he's walking along our road, or outside chatting with another neighbor.
