Great write up overall but as someone who has bought a couple of businesses, it is not just the seller who loses out if a buyer backs out. The buyer can also spend lot of time/money vetting the business including legal fee etc during due diligence. On a recent deal, I spent over 10k as a buyer until we finalized the APA. If the deal fell through after that (possible), I would have lost that money and the months of time of course.
