My real estate agent claims this has 5.9% cap rate - thoughts?

[Ian Goodstein]

Long time listener, first time caller. A real estate agent I have been working with in Los Angeles claims this property has a cap rate of 6%.

When I calculate it, I get a cap rate of 1.5%.

I am new to this and I'm curious what others get as the cap rate? I am trying to complete my first deal in the Los Angeles area, and I'm looking to learn all I can to avoid buying a bad deal. Thanks in advance for any replies.
