hi just wanna give you my comment based on the practice we have here. im with real estate and we are also the landlord.

Normally, lease contracts say that in case of pre-termination, the tenant has to pay the rest of the period of the contract. However, if your landlord is kind enough not to charge you the full contract, there is penalty based on your monthly rent equivalent to one or two months.

It also depends on the reason for early termination.
