Questions around Termed lease agreement

[Ana Vhan]

Hi all, 

Current tenant at our WA property has been nothing but a headache. He constantly fights, did not renew previous lease and that went into a month to month lease and reduced our options as a landlord. This year we paid a good amount to a lawyer and he prepared a "Termed lease agreement" and got it signed from the tenants. 

Its clearly stated in the lease that this is a termed lease and does not enter into month to month. Also that, landlord and tenant need to sign a new lease 70 days before the current lease is over. The landlord can terminate the lease by giving 60 days notice prior to the termination of the lease. 

I still have following questions given the fact that the washington state favor tenants generally speaking,

1. Based on this, if we give a termination notice 60 days prior to termination, will the tenants have to leave or is there any scenario in which they may still be allowed to stay?

2. I have noticed these tenants don't read anything. They may have missed these important facts in the lease. 2 months notice may catch them off-guard. Should I give them early enough notice like 4 months in advance so they get enough time to find another place?

3. are there any better ideas to let these tenants leave? Its been a nightmare to deal with them. 

Thanks,

Ana
