Check out the property taxes to determine if defaulted and address where bills are sent.

I intend to get a single family residence, add an ADU, live myself in the residence and rent out the ADU as a studio apartment long term.I have checked my city's ADU laws and long term renting is permitted.Question : can I obtain the REP status while maintaining the ADU while it is in my primary residence?

I find that it's almost a one stop shop in that I can use it for my business checking and savings accounts, bookkeeping, for rent collection, I can issue virtual credit card, I can create all the financial reports I need to run my real estate business and prepare for tax filing and through their partners I can vet my tenants, develop state-specific leases and more.

You can also check meetup.com or search Facebook for real estate investment groups, clubs, or meetings in your area.

When you say that you will "screen" prior to showing, does that mean a full application with backrgound and credit checks?

You can reach out to local agent networking groups, or check with a broker to see if they have someone in their brokerage willing to do it.

I’ll also call code enforcement and check the county records just to see when things like roof/hvac have been done/permitted. 

main challenge currently is finding quality tenants that can go thru my screening process (600+ credit score, clean background check, etc.)

I'd check your local landlord associations to see what forms they have to get.
