Franchise Transfer Equity Injection

Hey everyone!

I'm just beginning my search journey and leaning very heavily towards existing franchises.

I would love to better understand general equity injection requirements from the franchisor and/or debt lenders. Most of the material I've reviewed centers around new franchise territory acquisitions, not transfers. Recently, I've run into a deal stating that the franchisor is requiring a 25% equity injection.

Is this negotiable? Can seller financing contribute to the injection? Other advice, feedback, and guidance welcomed!

Thanks!
