It sounds like the $1300 could be the deposit and last month’s rent (meaning when you move out) and the $250 represents a pro-rated amount for February. But, I’m a stranger on the internet that hasn’t read your lease. You should still contact your landlord to confirm.

When does your lease start? It sounds like you moved in mid-month so that $250 might be pro-rated for February or may be some other cost. You’re probably best served by asking “what does this fee represent?” in writing to your landlord so that you’re both on the same page as to what you’re paying.

You will need to provide more information about your situation for anyone to provide meaningful advice. What did the 1300 cover? What is the prorated rent for? What does your lease agreement state?
