Please do not use the free lease generated through Appfolio. They are not up to date with all of our Oregon specific laws and using it could get you into trouble. I think you would spend a big chunk of money having an attorney review the documents, and then draft amendments to make it state compliant.
Instead, I recommend buying your leasing forms from one of the landlord tenant associations (the forms will cost you less than $150). The local landlord associations have a team of landlord tenant attorneys familiar with local regulations and update the forms as soon as new legislation passes. My top two recommendations for forms are through https://www.multifamilynw.org/ or https://rhaoregon.org/
I did a google search, and it looks like you have a local Assocation in Salem. https://salemrha.com/ Give them a try as well, there may be rules specific to Marion County that are different than the Portland Metro where I am based.
Also, if you join the association, they have a resource hotline for landlords where you can ask questions.
