Why all the investors not using LLC if expenses can be pre-taxed?

[Ben Waismann]

Hey all
I am new to this! Just bought my first house, and with my considerations of naming the house after me or after my newly opened LLC, I do some research.

So with the discussion of an LLC versus personal home ownership, people usually talk about liability and privacy.

But If I understand the logic,
If I get a 2000 rent payment this month to my LLC, I can buy a new dryer and washing machine with PRE TAX money and at the end of the year, it will be as an expense - thing that we cannot with having the house registered to ourselves. same thing in re-investing the money.

Can someone explain to me that logic?

Thank you all!
