YOUR perspective is excellent. A fee to rent is called the rent. NO two parties can be
obligated to pay the same rent........meaning, if john leaves a unit early, and
there is no replacement for 1 mo, John owes for the entire month. IF John finds a replacement
after 1 week, the landlord may not charge john for more than the length of time he was
a tenant.
While some Landlords claim costs and operation expenses, most courts will not permit the Landlord to "double bill." As soon as the unit is rented, the premature tenant's obligation
ends. I suggest you sue the LL for not returning all the prepaid rent/deposit owed to you.
IF you win, you also get 3x the amount going to you in penalties.
If you lose, you lose almost nothing
