But a multi member LLC files it's own return. 

My fiance and I own a property in south Everett WA.

You can learn to do this on your own or get a rockstar REALTOR to lead the way.

Until then, your state and local government will affect your property ten thousand times more than climate change, probably more. to add to this the Oregon coast is fairly remote and hard to get to unless you have your own airplane. 

So, it seems you are trying to do this all on your own, NOT a good Idea.

The vast majority of lawsuits against Landlords are for wrongful eviction, security deposit disputes, and Fair Housing Violations.

You picked great zip codes - I own (or have owned) in all that you have listed. 

As noted above, even though Fair Oaks is a mere 20 minutes from East Cobb, the respective markets are vastly different.

Was the owner doing his own repairs and hiding the costs?  

Maybe work in the RE business somehow; lending, assistant to an agent, the trades or start your own business like lawncare or landscaping to generate money.
