Thanks to various factors like taxation etc., but this is and has been an established fact for pretty much forever.

Donald, I recommend finding an accountant that specializes in real estate taxation.

The pass-through would occur in the partnership or s-corporation scenario.The taxation of the income would depend on the designation of the taxpayer whether they are considered a real estate professional or passive investor as well as whether they are renting or flipping for example.  

I think the intent of UBIT is to keep BUSINESSES on the same level playing field with respect to taxation.

@Joshua Callanan In Maryland, I go to the Department of Taxation website and search the legal entity search.

@Lotta Rozenson,I recommend finding an accountant that specializes in real estate taxation.

I also have an aptitude for taxation issues so I find doing my own buy and hold business taxes via my pass through LLC to be any effort at all thanks to turbo tax premium.

Also are there any differences when it comes to taxation?

Your tax preparer does not have to invest him or herself but certainly should know real estate taxation hands down. 

If there are any CPAs out there that specializes in personal taxation, that would be great.
