u dont need to entertain those interest bidders.
even bank or bank representative has no right to come into the house.

but its wise u start to look for a new house.

if the house is successfully auctioned off, u still need to move off within 3 months.

btw, u need to discuss with you landlord, maybe u can utilize the deposit to se off your rental as i dont think landlord can return the deposit to u at later stage.
