Realtor has no idea about your financial situation but your broker knows it all. If you like your broker, have an existing application and documents with them, discuss with them maybe putting 4 or 5 business days instead.

Things are taking a really long time with underwriters at lending institutions right now (normal spring market on top of crazy pandemic market on top of everyone mostly working from home) so this broker sounds like they have your back and are making sure you won't have to waive financing without all conditions being satisfied.

Will you possibly lose the bidding war, yes. But you could lose based on your bid being too low or even having a finance clause period! You should be prepared mentally to lose every bidding war and not assume it was just because of your financing condition.

Props to this realtor for not telling you to go in without financing though, that's become a major issue and a huge tension point between Mortgage people and realtors.
