​Wanting to get a $150k business loan to purchase 25% of existing business.

Opportunity has popped up.

Business is being sold for $600k because the owner is looking to retire.

After all expenses are paid, the business generates about $250k-$300k profit per year.

My friend is taking 50% of the company (business is his father’s) another one of my friends is either putting in $150k for 25% or $300k for 50%.

This feels like a once in a lifetime opportunity and I’m willing to see what possibilities I might be able to look into more.

I know this is very vague, but can anyone shed some light as to where I begin with all of this? I can answer any questions.
