You cannot get any relief if you do not take any action against the tenant when he has already vacated the premises.
Especially you cannot able to do anything on it by sitting in a far of place.
If you were already knowing about the tenant vacating the premises in advance you should have been prepared to receive the proeprty at the time he vacates the premises.
Your lethargy towards handling this critical issue will cost you dearly especially you cannot be able to recover the dues or damages from the tenant until and unless you hold back the earnest deposit or the advance amount .
If you do not want to break open the lock, you have no option than to send a send a legal notice either by yourself or through a lawyer demanding the tenant for a proper handover and delivering of the vacant possession of the premises.
If you do not want to get into legal action then yo may have to personally visit the tenant wherever he resides and pull his collar demanding your dues.
