I have been renting here for more years than I care to remember, as others have said, either (a) don't pay last two months rent, most common, and 'normal' landlords agree, or (b) exchange keys for cash (dont take a cheque) Too many friends and acquaintances over the years have been scammed by Hong Kong landlords that demand the whole bond or more, to cover cost of fictitious "damages". for OP I sympathize with your frustration, if less than 50K file a case immediately.
