The trade off course for STR route is more management/cleaning of guests coming and going/risk of no bookings vs not needing to deal with long term renters months at a time if that once they move in.

Frankly, no matter how well you do safety, dumb guests will find some way to hurt themselves so insurance is a top priority.

Guests and fireplaces always concern me. 

Guests love them, and listings with hot tubs often command higher nightly rates and occupancy.

I love the idea, and would likely become a guest as well.

Quote from @Joy Daniels: As a short-term property manager I've seen how this industry changes so often—new guest trends, tech tools, and regulations seem to pop up all the time.

Short-term rentals (STRs) could work well in vacation-heavy areas, but they require active management—considering a co-host or property manager can help offset time constraints.

I now offer "limited service" as a PM for 10% which includes marketing on 20+ channels, 24/7 guest communication, daily pricing, automations and software connections, but it is 10% of revenue. 

Tax deductions / write-offs should be a second concern.There are some rules that you need to follow to treat a short-term rental as 'active'(non passive) income which would allow you to offset it against other forms of income such as rental income / wages.

My wife and I moved to main house and rent the guest house as STR What made you interested in investing in this type of deal?
