You are not buying an asset. You are becoming the second founder of a business that already has customers, staff and a name in its town.
Write a profile of what you would build, and owners come to you. It is not a listing — it is what you would do with a business like theirs.
From the first message onward, you are talking to the person who built it — not a broker, not a process.
Businesses that are not listed anywhere else, because their owners are not shopping them around.
Write the profile owners read before anyone talks numbers — who you are, what you'd carry forward, and what you're looking for.
