Tax question - owning home vs still having a mortgage

[Christopher Butterstone]

If i own a house (no mortgage) and rent it out for 1600 dollars. Is that 1600 dollars considered income and have to pay taxes on. Vs if i had a mortgage and 1000 of that 1600 goes to my mortgage and 600 goes into a “repair fund” or some sort account strictly for maintenance on that property.

How does that work? Does having an LLC owning that property benefit me?

If i personally own the property. How can that property then become owned by the LLC?

Any input is appreciated. In Florida if that makes a difference
