I managed in CA, and the owner I worked for had a membership to the local apartment association, but I much preferred the Nolo Press contracts and forms, so I used them instead with the owner's blessing.You might want to see if they have WA contracts/forms.  

I prefer the Nolo Press contracts.  

This is a small incentive to keep them there another year and will be cheaper than a unit turnover,a win-win for both sides.The point is don't let your tenants try to press you for things constantly or control the situation.

If you dont' already know the landlord-tenant laws, you should learn them and find out if there are any restrictions on how much you can raise the rents or how often, etc.I highly suggest the Nolo Press landlord books. 

“Give and it will be given to you, pressed down, shaken together and running over...”

But I have a person messaging me about section 8 and after repeated messages of telling him politely that we don’t accept section 8, he keeps pressing.

I think you can hire a property manager for your  first year when you are learning and you seem pressed for time.

Don't quote me, but basically the fact is that  you're going to be hard pressed to find someone that has nearly $1500 for a deposit PLUS the first month's rent to move in. 

It cost us thousands of dollars and the vengeful tenants trashed the house to the point that we should have pressed charges on them. 

I'm disappointed with the one from Nolo Press.
