Commercial closings are trickier than residential because you have to look at zoning restrictions, there are details in the history of ownership from the corporations in the deal, and you could come across niche asset classes like co-ops where owners bought into the building like a corporation.  The biggest difference is that you’re working with two entities rather than two people with commercial closings. This adds layers of complexity because each company or corporation will want to protect their assets as best as possible, and there’s additional legal work.  Especially in the due diligence step. And because commercial real estate tends to be more expensive than residential, the closing process needs to make sure the buyer will be able to make payments before they clear the title.
