Just follow the Golden Rule of Landlording: Be Compliant, consistent and fair, everything else will fall into place.

So even if I chose to evict, Sec 8 will continue to pay as long as I'm compliant with the HA lease and the tenant still lives in the house.  

I understand your opinion, I agree that you have the freedom to conduct your business the way you see fit so long as you are compliant.

Granted almost everyone has something bad to say on the web, so you have to look at volume and what they are complaining about.As for as the fund I told you about, they are listed on a major site, set up by an attorney that specializes in this, & SCC approved and compliant.  

Instead, educate yourself and use your attorney for the following: drafting a lease that is compliant with state and Fair Housing laws; reviewing your written rental criteria for any Fair Housing violations, and representing you in court in cases of eviction proceedings.

My current plan is to cite that section from the RCW and essentially state that I am in my rights as the landlord, but I don't want that action to provoke her or worse, find out that my justification was not compliant with the RCW. 

to stay compliant 2. 

To be compliant, generally speaking 1. you shouldn't ask anything of one applicant that you don't intend to ask of others  and 2.  

Previous landlord simply answers couple of "compliant" questions and hits submit.

As others have mentioned, you can raise them over time, stagger them, start with non-compliant tenants, handle one at a time, provide a long notice period, take care of deferred maintenance, offer a lease incentive in the form of some type interior upgrade (new lighting, carpet cleaning, get creative).Substitute the appropriate assumptions in the equation above.
