And the laws and regulations here are very different, not very strict like the states.Prices are high and rents are low over here.

I'm looking for advice on whether I should purchase my father-in-law's 6 unit apartment in Burien, WA (10 minutes south of Seattle) as my first deal, or perhaps help find him a seller that would pay more than I could and is a couple years ahead of me in REI. 

If you switch to or stay with the custom tax settings, you'll need to update the amount of tax collected to 7.75% because the 9% city tax will be collected and remitted by law to the city on your behalf, but  the 6% state and 1.75% county tax will be collected and sent to you to remit to the state and via Avenu to the county.

Law websites like nolo and others have said if the tenant in NJ has made partial payments then you have to give them 30-day notice before you begin the eviction process.

You state that you have 20% - 25% equity position for safety, but you don't based on the information you gave. 

Know and obey the law.

If not, I most definitely would reach out to the tenant, introduce myself and ask if they are going to be out by the 31st or the 1st, I would communicate  to the tenant as if I know they were told they are expected to leave, otherwise you may find they "do not know" they need to leave even if they actually know they need to leave....In the case they claim they are not aware they need to leave, you would need to follow the laws in the state you purchased the property, usually you can find that info on the states judicial branch or speak with a landlord tenant attorney. 

It is true what someone told me once: getting my license can get me into trouble more quickly than doing wholesaling deals properly (following state law).
