With that short list I made spreadsheet and included the following for each city...1) Annual visitors - really easy to look up on Google2) Median home price - I think I used Zillow3) Airbnb Revenue - I got this directly from Airbnb.

Lease says no more than the original 2 tenants.  55+ community with covenants saying underage visitors no more than 14 days.

Orange Beach & neighboring Gulf Shores AL has already been through that cycle where areas outside of the primary beach zone originally  designed to accommodate primary residences are now restricted, but the major tourist areas closest to the beach are exempt, creating a balance for residents & the visitors which are so vital to our local economy!  

An attorney from Ohio responded back that I am not allow to restrict guns on my tenants, as a matter of fact even their visitors are allowed to pack.

Many of the personal visitors I've had over the years really just wanted to hang out at the house and chill.

They rent units to house executives and visitors who visit the US office of a multinational corporation on a regular basis.

In mine, I had it range from temperature on the thermostat to visitors to cleanliness to laundry/kitchen use to number of people over night.We talked over the phone and made it SUPER detail.

Consider some sort of incentive to get visitors to leave a review if they start dwindling.

As far as landlord entry, if it were me, I'd find some sort of private motion alarm, one that has a programmable visitor code so they don't have to give the landlord the permanent code, and let him know he needs to contact them for an updated visitor code whenever he is coming in if they will not be home.

A guest or visitor who is injured due to untreated snow or ice will likely sue both the property owner and the tenant.
