You can but you can end in prison.

This is not like USA were you shoot anyone who enters in your property.

If you harm this people you surely will have to face penal consequences.

Why? Because then, people will do the same with a small family which can not pay rent this month, after you increased the price to the double because you want to rent to tourists.

The solution is simple: use your properties. Would you let your car with the keys inside? No. Don't let your houses unused. It's is an offense to people who want to work and live. Properties shouldn't be a business nor a speculative means.
