Restuarant Acquisition with Property

We have an offer accepted on this business. Have the manager of 15 years as the majority shareholder who is willing to sign a PG and have 10% equity. We can do SBA but due to the planned equity split would prefer to explore other non-SBA options. As the property valuation is around $600,000 and a PG would like to keep equity at 50 % for a major shareholder who is day-to-day and signing a PG. 25 % for Equity partner and 25% for the remaining two partners.
