Should I establish a business entity for my first rental?

[Oswald Gomez]

25M from Sacramento, CA and I bought my first rental home in June of 2019. I plan on purchasing more once I save up enough for closing costs again. Now my question is, should I establish a corporation entity for my rental in order to claim the business as additional income? When I apply for the second loan would they consider the debt from the first mortgage as taken care of from the rent? I apologize in advance if this is a silly question I am very very new at this. Thank you!
