Tenant not paying rent, eviction process

[Kevin Oh]

I am a new real estate investor, I have two properties. Both tenants have their lease up and I gave them new leases. Tenant A received the lease and did not pay or acknowledge she is going to sign. Tenant A has been a problem with not paying in the past, I went to the eviction office today and filed an eviction for Tenant A. I just bought another property for a house hack and gave lease agreements to all the tenants. 

This one tenant is giving me some serious problems (tenant B). Tenant B is on Month to Month with the original seller, I gave Tenant B the lease agreement for month to month, I signed it and was waiting for her signature. Tenant B signed it but added an additional clause. The contract is now void. I am going to give tenant B a 30 day notice. I may have to file for eviction. 

My question: Even with eviction notice or 30 day notice, does the tenants have to pay for rent? If they do not, how would I get the rent from them? What would be the next step?
