I have a deal under LOI. The business is $2.7M and real estate is $1.9M. I will need additional capital to get the deal done as I only have $400k in cash. What is the going rate/terms for a $600k investment from a private investor?

Average GR: $3.4M
Average GM: 43%
Average EBITDA: $840k
Average EBITDA Margin: 24.6%:
