Landlord increase rent in flexible period?
I just got notified by my Hong Kong landlord that they are increasing my rent by 20 percent to match the market rate. I just finished my fixed period of rent and flexible period will start. During contract signing nothing of this sort was mentioned. I understand that I got below market rate rent only because the condition of house given to me was pathetic so I had to repair it by my own pocket. But as my fixed period ended they increased the rent by 20 percent. I just want to know if this is allowed and how can I fight it or just accept the new rent ?
