If you used TransUnion to screen, they are also required to provide the applicant with an "adverse action" letter, detailing the screening company’s contact information for follow-up.

That's the first step, just start with any small action and keep learning, and stay connected and again highly recommend the local real estate meetings. 

Most likely the state where the property is located is where lawsuits would be brought if they are something for personal injury like a trip and fall or something of that nature because the “cause of action” arose in that state.

This will allow for you to pursue legal action "eviction" if ever needed for non payment or negligence as a tenant. if you rent out the basement separately but it is not a legal unit, the court will not allow you to pursue an eviction.

So:When tenant is not doing what they agreed to do or what they should be doing or what you would like him to do, instead of allowing yourself to respond by getting stressed out, spend the time planning your actions.

Welcome and congrats on taking some action.

This would be considered a no fault just cause eviction since it's based on the landlord's actions--wanting to move back into the property.

I know I need to find a way to start taking action but don’t quite know what that is right now, I’d love to get some feedback/thoughts on what those next steps should look like. 

So, you probably cannot take immediate action.

Thank you Rayna, that is VERY encouraging news, especially for you!
