Seeking Non-SBA / Non-PG debt providers

Working with a searcher on a small business with real estate. The goal is to acquire the business and property. Each appears to be worth roughly $2.5 million, totaling a $5 million package. Searcher wants to avoid a PG. I doubt the SBA is an option. He has some rental properties that could be leveraged. We don't know how much seller financing is available yet. Please reach out with helpful suggestions.
