If such cases should arise, you have to make sure that you have some kind of clause in your rent contract. If the guy gives you an rabic contract, make sure to get it translated before you sign and ask him to add such details in the main contract. Plus it is normal practice to in some places to take a maximum of 3 months advance but this is for settling the last months rent and other liabilities.

Do not take places where you are forced or asked to pay such advances if not the direct owner. Middle men are thieves and there is plenty of them around.
