This might undercount (if owners don't file the form) or overcount (tax fraud or error), but there's financial incentives to get it right on both sides, so it's probably fairly accurate.

* Multi-ownership can be easier. I.e. you can "hide" who owns the house and it disconnects ownership from property records.
* People think it adds liability protections.
* It might make transferring the house at death easier to control(i.e. LLC rules apply, not state real estate rules)
In the case of owning the house you live in under an LLC, the chances of it protecting you from most liability is 0%. The only thing I can think og it maybe protecting you from is debt obligations, if the person trying to collect from you didn't bother to find out why you don't own your house on property records. This probably has a very low chance of working anymore, but low is > 0 I guess.
In order to have LLC liability protections you have to separate the LLC from your personal life, i.e. you have to treat the LLC as a real business, no mixing bank accounts, etc
Simply looking for properties owned by corporations will get you really close.
