I'm looking at a 25 year old auto-body workshop and the seller owns the real estate and wants to sell business only and rent out the real estate into the future. In principle, this seems to make sense. With the rent adjustment factored in, it's selling for a fair price relative to earnings.

Maybe I'm being paranoid, but is there a risk that post-sale the seller somehow crashes the business (by hiring away key workers to a friend or bad-mouthing the company, etc.) and then re-establishes the company under a new name in the same location?

Obviously, there would be a non-compete, but it seems to me that a seller who takes the role of landlord post-sale has huge leverage over the company into the future.

Am I reasonable to be concerned about this?
