Maybe there was something else unattractive about your offer and the 2.8 fell through? Happens all the time.
When I sold a house recently I took the second highest offer, because the highest offer came from someone out of state who had never set foot in the house
Yes, the issue was increased risk of the buyer backing out. In which case I would get a few grand in earnest money and have to relist (or hope the other potential buyers haven’t found something else in the meantime and still want to go through with their offer).
The house had some warts, and the second highest bidders were locals who had toured the house and had it inspected. Closing was pretty much a lock.
