Holding LLC - CPA Input Requested

[Theo Z.]

I hold each of my properties in its own LLC and have been paying my CPA $650 per entity to file returns every year. Someone mentioned it's possible to create "an LLC holding company" that holds all the other LLC's and in that way I would only have to pay my CPA to file one set of tax returns each year.

But I can't find any additional firm information on this. My CPA is the person I would usually go to with a question like this, but I obviously would rather not due to the nature of this particular question. I would really appreciate getting input, especially from other CPAs, about this issue. I'm not trying to shortchange my CPA for the good work that he does, but am trying to figure out if maybe I've been doing this wrong.
