I think the saddest thing about renting on Airbnb (which is so much better than VRBO), is that
people lie. Not every guest, of course, but about 1/2 of the guests I have had over the past 2 years either OMIT or outright LIE. Why? Money. They don't tell you about extra guests because you have a limit and they don't want to pay more for a larger place. Or, in my daughters case, she charges $30/per person per night over the max number allowed. All of this is in her rules, which people may or may not read. Also, both my house and my daughter's is pet friendly (which for guests is hard to come by, I think) and she charges a one time $50 pet fee.
Her latest guest said 6 adults and no pets, children. This guest actually has an Airbnb himself. You guessed it. A baby under 2 years of age (not allowed) as (dirty) diapers were left behind, and at least one dog. When I ask him about the pet fee, he says no dog was there but then where
did that black and white dog hair come from? Plus the doggy urine smell in the laundry room and the plastic container of water (with dog hair in it) left in the laundry room? I take pictures after the guests leave but I think a camera system outside etc would be beneficial. Especially if it works with nest.
I find this to be the biggest issue for us with renting out our very nice, remodeled homes.
Airbnb has been helpful with the few really bad cases, but when it comes to things like extra guests or lying about a pet or two, well, you know.
Also, just a bit of info: if you have a marijuana smell in the house, i.e. bedroom etc, my advice is to get a small bucket or two and fill it with unadorned bbq charcoal (old fashioned kind) and set it in the room that smells. Charcoal absorbs odors and it does work.
Even though I get a bit cynical when guests, especially those that are hosts themselves, try to skirt the truth to save $50 bucks or so, my daughter and I have had good experiences with guests and we still rent our places on Airbnb. We've been doing it for about 9 years now. So hang in there, Jo & Ji
