making my primary residence to a rental property

[Leo Martinez]

HI, we purchase our primary house in April 2022 and we are thinking of moving to a new house sometime next year. my questions are the ff: thank you in advance for the advice. we are really want to learn about rentals and hoping this would be our start. 

 1.) do we have to wait for 2 years to have it legally rented?

2.) do we have to report it to our mortgage loan company and will it affect our interest rate?

3.) do I have to have LLC to start renting it out or is there a possibility to transfer it to LLC?
