Hi, There are 3 apartments in a complex for sales. I chose one of them, paid 0.25% deposit. I called the other real estate agent to say that I chose X over yours, please tell the vendor I am not buying hers now. Then the vendor gave a big discount and looks hurry to sell. This made me feel this building suspicious. Please have a look at the pictures taken at the lowest level of the basement. How serious is it, and how sure is it? Water leaking at the basement.
