More and more high paying professionals moving out this way to work at ESRI.

I sincerely doubt such a list exists, although each mortgage lender would know which of their own borrowers is behind, of course.

cash flowing requires more creative, and therefore higher risk, strategies.so, of course, you will likely cash flow if you buy in all cash. 

What I'm trying to say is that I recommed giving us more details or if you don't want to put personal info on the internet find a in-person tax professional or accountant who is familiar with rental property taxation to determine your eligibility for deducting rental losses and ensure that you're compliant with tax regulations.

But that's no guarantee.And, you can follow all good screening procedures, professionally run your business, and don't get too cozy with your neighbor/tenant.After that, roll the dice. 

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

If you want your rental to be successful, you must continually educate yourself, have strong policies and procedures, and be prepared to take action against bad behavior.The best thing you can do right now is start looking for a professional property manager.

Steady state, the property should generate about $12-13K in rental income monthly (I will likely live in the ADU to begin with, which would reduce the income of course).

However, I'm also a travel professional and am usually away from my home months at a time for each contract that I do.

Location, professional photos, great management.
