> If they do, it takes years to find a buyer and they are getting a low sale price.

Is this true of standard businesses like laundromat or plumbing?

Or is it a matter of such businesses rarely being in a condition that makes a sale easy? If these are in a good condition accounting-wise for example, they should integrate readily and for a basic multiple of sales into one of the neighbors?

What I have seen is unrealistic prices - and that's another matter.
