Hire a company/person that is solely a QI like @Dave Foster they do it every day and will keep you legal and on track. 

Let me know if you'd like more details or assistance!

I feel like it would be great to trust a property management company on all of this, but it would be hard not to step in if you could do a better job at screening bad tenants (eg screening HUGE future problems).I initially managed properties myself, but now I delegate that responsibility to my business partner, personal assistant, or a property manager at my brokerage.Most PMs I know will send you an applicant for final approval and you can get on the phone with them and ask them questions

A realtor's role is to assist in your buying or selling process.

We are able to assist you being a foreign national 

Granted I did work on the RE items throughout the calendar year, but I didn't track the time. 

I've done pretty well as a relatively novice investor in the stock market, just investing in S&P 500 tracking index funds.

They already have a track record (good or bad) with you, so you can decide based on payment history, inspections, etc.

I am just starting my investment journey, so have only used Real Estate Agents to assist with buying and selling my primary residence. 

Those details can ensure your projected $25K profit stays on track.
