Tenant breaking lease

[John Kai]

My tenant just informed us that they were terminating a 2-yr lease with 10 months remaining on contract. We have a signed, executed lease agreement and did not mutually agree to terminate lease. The monthly lease was $3,500 and this translates into $35,000 in lost revenue. In the state of Hawaii, I have a duty to mitigate my losses by re-listing the property once I have possession on Dec 13th. If I am successful in finding a new tenant, I can then sue for damages, losses, expenses and including attorney fees. Any thoughts or issues that I should be aware of that I might not be thinking about? Your help and input is appreciated. Aloha and Happy Holidays! John
