An opportunity came up through a family friend to purchase their business for $30 million dollars. How would you all recommend financing a deal of this size? Some stats about the deal below.

Purchase price: $30 million (5x EBITDA)
EBITDA: $6 million
Seller is willing to roll 30% equity + a 20% sellers note
I am not in the position to inject a significant amount of equity into the deal.

All input appreciated.
