How difficult is it to invest in certain small businesses?
My wife and I live in a city of about a million people in one of the southeastern states. We already are well diversified in equities, crypto, precious metals, as well as 2 properties. 1 is a 2 bedroom condo in a tourist area near the beach which we rent out thru Airbnb, or stay there ourselves when it's not being rented. The other is a small 2 bedrooom house with a reliable permanent tenant.
We were thinking of buying a small business but we know nothing about that. Something that takes minimum effort, just as yet another form of diversification. We know restaurants and delis are bad ideas. Her idea was a car wash. My idea was a small DIY storage center. We have about 500k to sink into this. Does anyone know anything about either of these? Are any of them viable business ideas? Or is it something like good businesses making money aren't sold, only the ones losing it are for sale and so we should just stick to buying more houses to rent and index funds?

I have a yearly income of 165k, should I buy a second house?
