How do i update the current lease agreement to remove his name?

You should be able to get the tenant to sign an agreement that in exchange for the two extra weeks they will leave by end of that final day.Waiting to see what a tenant is going to do can be really aggrevating, but the eviction process should be a last resort, and shouldn't be started if you've accepted rent. 

They want an old fashion in person signing of the agreement.

Our rate lock runs out at the end of the week as well as the current sale agreement extension.

I signed a one year buyers agent agreement before I became aware that this is really high.

That seems not to have happened here, but that doesn't represent an ethical breach.BTW, you can still submit a higher offer if the property hasn't sold, even if the agent says it's under agreement. 

When I house hacked my first property, he proposed an agreement with the tenant on a new rent price upfront because the verbiage of SB608 is so poorly written by politicians.

It might involve changing the membership of the LLC, dropping all of the members out of the LLC into a tenants-in-common structure, or doing some type of redemption agreement. 

How many showings usually you need to do to have the leasing agreement signed?
