Did I misinterpret an agent?

[Account Closed]

I had a lengthy discussion with an agent/investor/property manager. I'm trying to get my foot in the door and I met her at a SCORE session as she was the main speaker. From what I've read here (and what I want) is cash flow not bank on appreciation. I live in the very volatile market of South Florida. She said I shouldn't look for cash flow just have the tenants be paying my mortgage to build equity. I was a little surprised by that as the rents here now would not even cover the mortgage as it's expensive again in South Florida. Am I misinterpreting her? Thanks
