All landlords are not stable in ownership. The stakes in the biggest markets are beyond numbers that any individual or small business could ever dream of purchasing…in the current market.
That’s why property ownership changes so often. You can look at how many arrests for wire fraud racketeering money laundering bribery ponzi schemes  are made in THESE real estate sectors before during or after the fact of flip after flip of large commercial properties….in THESE markets.

It’s also a market that’s driven by the invest of OPM (other peoples money) into REITs and many of those small individual investors are left with no chair when the music stops playing.
 

If this was true there would be no corner stores or any small businesses left in LA or NY.
All neighborhoods eventually get redeveloped or rot and fall down,  the original owners (Mom & Pop) are the ones that start the cycle by getting more than market value.
In my case I paid 120,000 in 1998, with redevelopment of the area and time it’s now worth 500,000, I would take 750,000. The rent would justify the 500,000 but I still want 750,000. If I put a sign out I might get it, the new landlord will have to cover the cost with rent increases. That’s business. If the tenants don’t like it the new tenants will.
