How to deal with a deceased tenant?

[Gerard Charles]

Hello!  Yesterday,  I received an email from a deceased tenant's niece saying he passed away.  He was an elderly man. His extension contracts ends on Jan. 31st 2017.  His niece stated they will vacate the premises by the end of the month. That had me speed up to start the ad, and drive 5 hours to inspect, and show prospective tenants the property. 

My concern is there's less than 2 weeks notice and worst around the holidays.  Should I have them to extend it to 30 days notice as per contract. 

The tenant didn't leave any contact heirs on his contracts. The niece stated she is handling his affairs.

I see on the contract : EARLY TERMINATION: Tenant is not entitled to early termination due to voluntary or involuntary jobs or school transfer, .......loss of employment, ...... or death. So doesn't that means till the contract ends which is in 6 weeks.

Thanks in advance for any guidance or suggestions.
