Once you decided to buy a unit in Kuala Lumpur, I felt dissapointed that you and mother did not ask my opinion before buying a house. To make an informed decision, you suppossed to be requested to acess any risk may occur, and implement mitigation plans. The idea that I have heard only the greedy ideas that the housing prices will be increasing after LRT established. As we know, if government wants to build the infractructures, it should take at least 5~ 10 years and the traffic jam will never ending until the infrastructure has been finished. You were easily to be tricked when somebody told you that it must be increasing surprisingly.
On the behalf of a older sister, you should be responsible to take care all of the financial status in family. Since you asked me and brother to come to Germany with you. You are destroying our lives, do you know? If you were not studying in Germany, you could save more and earn more money than now. You do not need to ask mother to pay a downpayment and lost her retirement money for the rest of her life. Our father also would not suffered depressed to live in a small room with mother for almost 3 years during the pandemic.
