Based on auction instructions that I saw before this in pejabat tanah. Usually the auction house need to post it somewhere for public to see 2-3 week before auction.
So yeah probably.

Yes. But can always refer to the old previous POS. Usually nothing changed a lot in the T&C. Just the pricing and date to be updated only.

Which lelong unit u interested ?

Some agent provide assistant as runner to help you change the following details as well.
All the below mention stuff you have to settle yourself as you are buying via lelong. Cheap things surely need more work of course.

p/s: for TNB. got trick no need pay the outstanding amount. can absorb to the ex owner name. just change name and start brand new account number.
