How do I find commercial shopping centers that are not on the market?

[Moises G.]

I have a few big money investors/buyers who are picking up shopping centers in Southern California, Arizona, New York, etc. They want me to find them more non listed properties with good numbers, solid anchor tenants, and so on....

My question is what would be the best way to find non-listed shopping centers, strip malls, and other income producing commercial properties for my buyers? I was told by someone that I may want to contact some private equity firms and see if they have any inventory available. Is this solid advice, and if so are there any other suggestions or approaches I could take to find more properties? Any feedback or advice would be greatly appreciated as my buyers are picking countless amounts of properties and I would love to send them more assets to add to their portfolio.

Thanks in advance
