Home search cash only but have loan

[Joy Z.]

I want to my a pre-auction offer on a property, seller's agent says I can make cash only offer even though Homesearch says cash only. I have financing and not cash in hand. Homesearch says cash only means cash only and I can lose my 3% deposit if offer accepted. Agent says doesn't matter. Has anyone made pre-auction offer on cash only but had a loan instead? How did bank handle situation?

Also is pre-auction good opportunity for a good deal?

Thanks
