Let us know what you end up doing?

Typically, if tenants need to vacate, the rent would be abated for that amount of time (just like a probate) until the time they are able to get back into the unit. 

The downstairs unit (1 bed/1 bath) I'm currently living in but I need to move back to Los Angeles at the end of the month.

If your tenants hate you or see you as an azzhole, it wont end well.  

They have now stopped repling to our commications since I told them that they would not have the option of extending their lease at the end of the six month term [option to extend was contingent on 6 on time monthly payments].

2) On the second 'Hone Your Skills' bullet point, I'm getting an answer of $57000, not $63k like the back of the book says

Did you end up moving forward with the project?
