I have hosted over 3,000 guests. And my experience booking locals has only lead to problems and big $$$ costs.
I was getting last min bookings around 6pm and Mrs. Meth and Mr. Crack show up to tweak all night. Stolen towels, pillows and up all night.
Here is how I book locals.
First make each listing avail in 24 hours.
Meth or Crack heads do not think ahead.
If a local is getting their home treated for bed bugs they will come stay with you! Yep we got bed bugs from a local . It cost us over $3000.
Unless you aspire to be on the next episode of Cops or Cheaters ignore the value of 24 hour notice. People who cheat will book your place but usually do not plan a head.
Locals will bring in their friends and in most cases more people will know the contents of your home. That way they can come back later and steal from you. We lost or bikes this way.
Locals will become that friend that you may not want to live that close to after they check out. They will expect more… like storage or cooking up a storm.
The city investigators may book your room to see if you are compliant with city regulations.
Hopefully this is an interesting topic. And I can say all of the above has happened to us.
