Yeah, I'm not getting the issue with this one either. They're renting out their house for $40 a night, which is nothing, if the people are willing to watch the dog. If I wanted to stay in that area for a month, that seems like an affordable way to do it as long as the dog sitting expectations aren't excessive.
As someone else said, looking after people’s pets when they are on holiday is a job. They should pay you to do that, not you pay them.
You can pay people to pop round a few times a day to feed and walk the dog and then clean up after them. I’d imagine that adding an overnight stay to look after them would be more expensive too.
So they basically want you to pay them for the privilege of looking after their dog.
Sounds like $40/night w/o dog, and $40 minus daily dog boarding cost/night with free dog. Depending on the local boarding cost, it might actually be free.
Under different circumstances it might make more sense. Like if it was for 8 months at a fraction of regular rent rates. But to try to get a house sitter for 1 month to pay you $40 a night? The balls…
