The big thing is always focus on protecting the public, disclose, and take care of people.

The landlord should be named on the tenant's insurance policy for additional protection and to assist with tracking compliance.

Also, take as many pictures as possible before the tenant moves in, again this protects you in case of damage caused by tenant. 

However, since you put the asset into an LLC, I am going assume you care about asset protection and further this discussion just a bit.My advice to you is to seek out local banks where much of their business is derived from commercial lending.

By recognizing the signs and implementing effective preventative measures, landlords and property managers can protect themselves from potential scams.

This gives much better diversification protection across geographies, asset types, strategies, investment subclasses etc. versus putting all the eggs into one basket.The downside is that it's not for everyone, and a person has to be comfortable with turning over control to someone else.

I'm not sure how to protect my value add strategy if in partnership and would prefer to outright own.

A business line of credit through your LLC protects personal assets, builds business credit, and may allow interest deductions, but it might be harder to secure for a new LLC.

Now, I see you are in Seattle, which much like Portland, has extensive tenant protections.

Another key benefit is diversification; an SDIRA allows you to include real estate in your portfolio, reducing risk by spreading your investments across different asset types, which isn’t possible with a standard IRA.Moreover, assets in an SDIRA often enjoy protection from creditors, adding a layer of security to your investments.
