The Bank will not talk to anyone, until it ready to LIST the property.
When they LIST the property, your Realtor will see appear in the MLS.
Then, and only then, will you be able to see the house and make an Offer.
Then the Bank will have their Agent sit on all offers for 7-10 days; so there will be no advantage in being the first, or trying to jump the gun.
Good luck and may God bless
