Pro-rated rent calculation for MTR

[Roman Puzey]

Hello,

How do we handle monthly payment for tenants that move in towards the end of the months like for example on 21st of the month and then they are moving out on 24th of the month 6 months later? Do we just make them pay the pro-rated rent from 21st until the end of the month or are they paying for the full month as soon as they move in plus the security deposit? Trying to figure out the verbiage in our contract where it says "The remainder shall be payable in equal monthly installments of blank amount each, due on or before the blank day of each and every calendar month throughout the lease Term, commencing on the blank day." Any thoughts? suggestions?
