I was just talking to friends that we'd never been to Branson...I'll have to keep you in mind!
1. Set clear rules and stick to your guns. One exception will lead to ten.
2. You live 45 minutes away. Consider installing an exterior camera even if it's a Ring doorbell. At my house, I use a Blink camera from Amaz-n and purchased a mount for it. They run on lithium batteries. They aren't the greatest but you will get movement notifications and you will be able to check on the number of cars in the driveway when you want. They require wi-fi in the house and there is a module you plug in. Just be sure to disclose this in the listing.
3. Take photos/video of the place before each guest. I take a video and state the date and the upcoming guest's name after I finish cleaning. This will give you a smidge of backup in case there are damages.
4. You way want to consider meeting long term guests in person upon check in just so you can get a sense of them in person and so they feel a sense of connection to you...it can help them feel more comfortable contacting you if they have questions or concerns.
5. Consider having someone come clean half way through the long term guest's stay. It can be just a kitchen and bathroom cleaning that takes an hour. It would give you an extra set of eyes inside in case this are going sideways...
