Tenant moves out early, how would you handle this?

[Andrey Y.]

I had a tenant that unfortunately had some financial difficulty and had to move out (her husband lost his job). I suspected this vaguely last month when the rent came in two separate installments.

She has payed up until the day she moved out (1 week into a new month, she is supposed to be out by tomorrow at the latest). She kept offering to pay an extra month if she needed to, which I declined. If she can't afford the rent, I don't want her to come up with more money.  They have only stayed 7 months out of their 2 year lease.

Legally in Honolulu or Hawaii, correct me if I am wrong, early termination of lease is forfeiture of the deposit? I will also lose some revenue in getting new tenants, possible some repairs (haven't looked yet). Thoughts on this?
