Franchise Model vs Oranic / M&A

I am looking for perspectives on acquisition of a franchise model, particularly from operators and searchers who have evaluated or completed franchise acquisitions as part of a search. I’m interested in how you assessed unit economics, franchisor support, and the balance between operational autonomy and system constraints versus acquiring an independent business. Would also welcome insights on financing structures (SBA vs. seller financing), post-acquisition value creation levers, and any lessons learned—positive or cautionary—when comparing franchise acquisition to a traditional search acquisition.
