If you qualify for an owner occupied purchase, no one check on yiu if you moved in.

If they do this, the seller is Already contractually committed, he doesn’t get to pick and choose, and the terms/closing timelines are already set.But on the other hand, since the other buyer Had the contingency of selling their current home, they likely can’t qualify for the loan on this house yet.
