For tax purposes and LLC does not exist. You simply have your choice of how you would like to be taxed.
First, you don’t need just a tax professional. You need a consistent advisor. Who will know your situation inside and out and can assess it regularly.
Second, Bill Walston is correct in what he said. I have MANY clients who operate both types of businesses. Most broker’s operate as an S-corp; however, an individual agent cannot elect S-corp status. That may be where you heard that rumor. (I would rather not get into explaining that right now) back on to the topic: Corporations are not ideal for holding real estate. Unless you elect S status and leave it that way from the beginning and even then It is more complicated than the situation needs to be.
Depending upon the cost either go with 1. a single member LLC or 2. keep it in your name. Either way you need a solid insurance policy in place.
