I have a client who thinks they should be classified as Real Estate Professionals. they have 16 separate rental units.

I checked the box  for RE professionals on their Federal information worksheet but nothing happened, there were no errors and it did not direct me to any other place on the return.

what are the main benefits of being a RE professional?

Could one of you wonderful people please help guide me thru this process?

As you can probably tell I have never had to deal with a RE professional

Thanks in advance
