Someone, I think it was @SeattleCPA pointed out the "P/E" ratio of buying a business is off the charts (on the good side). Of course, you are also buying a job (usually), but it is kind of intriguing.
I possibly did say this. If I didn't, let me say that I agree with the statement...
BTW, in our CPA firm, we regularly see people sell and buy businesses. And it can work really well. Though you need to be careful.
This is something that's more complicated than buying a house. It's pretty easy to determine roughly what a house is worth... and a home inspection shows whether there are problems... Further, you didn't typically need any special ability to live in house...
In comparison, you face more uncertainty IMHO about value. And due diligence won't necessarily identify the problems. Finally, you or I might not know enough to run the business we'd like to buy.
But, yup, you can get really good ROIs and even after calling a chunk of the profit "owner wages."
