Prorated rent question

[Abel Gudaye]

Im a little confused on prorated rent, I'll be grateful if someone can reconfirm this for me.

Example Commencement date June 13, 2019 and Expiration date June 30, 2020

prorated rent: on or before July 1, 2019 is 1,218.22

The rent is 2150.

So basically, once the tenant signs the lease the he owes the security deposit of 2150 and the rent of June of 2150. Then on the month of July pays 1,218.22 (for moving in the middle of the month) then goes back to paying 2150 every month, right?
