Tenant breaking one year lease after 2 and a half months.

[James Erickson]

I have some tenants who just got a job in another city.  They signed a one year lease and are moving at the end of this month, breaking the lease nine and a half months early.  I know that they are obligated for the full lease until I re-rent the apt.  Do I collect the full amount of rent remaining on the contract up front and then return the remaining balance when I re-rent the apt., or do I re-rent the apt. and then charge them for the time it was vacant?
