@Zoran25 if you will search this very forum, you will find many posts discussing this very problem.
One would reasonably expect your first scenario to be correct, however, what really happens is the second.
As to your question of what to do, here are some possibilities:
1) Reviews be darned, do whatever it takes to secure your property and let the chips fall where they may.
2) Vet guests VERY carefully pre-arrival and then hope that protects you from bad actors (charge a good rate, reiterate all your listing foibles and rules, find out who is coming - all of them, check ID, require good reviews)
3) Remain entirely unfazed during any bad behavior, hopefully preserving a good review from a guest and then reveal their bad behavior after their stay via your review of them
Other hosts might have more suggestions, and each of these has its downside. You'll have to decide what works for you.
Search: reviews, cancellation, House Rules, damage claims...
You could read for days, good luck
