Consulting with an experienced eviction attorney in Seattle is essential to confirm their status and to ensure you’re following the correct legal process for removing them, if necessary.Disclaimer: I am not an attorney or an eviction specialist, so this is not legal advice.

Agree , those are all incredibly important as is good property management and the ability to price the property correctly based on your competitors rates( dynamic pricing ) . 

First you need to learn to separate the following:Maintenance: usually things related to wear & tear or tenant damage.Repairs: usually broken items like doors & windows, caused by tenant or nature.Capital Improvements: usually expensive things that wear out: hot water tanks, furnaces, roofs, etc.The seller is correct that Repairs & Capital Improvement items should not be a factor for awhile (ALWAYS get your own inspection to confirm).

I will also add that many independent travelers that do room rentals enjoy having their own fridge.To keep things kosher in shared spaces, my friend who runs PadSplit says every room comes with one colors or plates cups etc to ensure that guests are accountable for their own dishes.

If there was a clear lease violation sufficiently serious and they were given written warnings to correct the issue and did not then you could probably evict.

That's not the case here; @Jay Hinrichs has it correct. :)

There is nothing illegal as long as the property is zoned correctly.
