when u buy subsale, it is "as is where is". the privilege is yrs to inspect with experts and pay deposit only when u are satisfied 100%. if u did not do that, u can't blame anyone.

see, a buyer can put 100 conditions incl termites and crocodiles, h1n1, but no seller give accept.

yr case, i see either you accept as it is or stand to lose yr deposit.

there are things in life u learn by mistake if u had not been careful - if the mistake is yrs and yrs alone.

sorry not being helpful, just being realistic.
