Rent a vacation home if, for example, my laptop is stolen and I have an insurance that also for vacation or just where I live?
Only in your home country. South Africa or Central America, for example, would be a completely different risk class than Germany, so insurance will not cover that.
You've got to have an extra theft insurance anyway, look at your policy.
A fairly contemporary home contents insurance also provides coverage in the context of the so-called external insurance, burglary also covers the resort. But then, as a VN, you also have to handle the valuables with due care and, consequently, include them consistently.
No. Included in the HR.
Can't say so flat rate. As it is here, you should look in the policy, if that is covered.
Theft (detailed burglary) of objects of the tenant of a holiday home are usually covered by the home contents insurance. However, some insurance companies also exclude electronic devices, but this may be the exception.
My tip: check the condition of your home contents insurance and if necessary contact the insurance (for example, about the service number).
