You can outsource marketing (any agent will list it), accounting (any CPA) but without relationship with Tenants you'll have constant problems.Such companies exist - they take phone calls 24/7 and then transfer them to PM to coordinate contractors.If you don't care about your bottom line, you can hire such a company: they will call to the most expensive plumber co, electric co, etc - you pay the money, they fix the problem.Fixing toilet would take you 10 min plus driving, they will call the plumbing company which takes $200 just to diagnose the issue (im not kidding - I've had such thing).

Continue educating yourself by reading books, listening to podcasts and networking with local RE PRO's.

Best to speak to a CPA who can advise you.

You learn the market out there looking at deals and networking with other investors.

@Andrew Hooper you can go to local REIA groups and network with the investors there.

Have a good CPA and  Realtor. 

The lender will need someone to sign on the loan with a balance sheet with 10% of the loan amount and a net work that is 100% of the loan amount.

In short, reading quality books and networking locally are two of the  most impactful things you can do to be successful!

Once you get income coming in then your time becomes more valuable at which point mentoring or coaching can be worth it.Side note, the more you network the more opportunity you have to learn and or get refferals.

@Karina Torres with all that schooling I'm sure you know the importance of networking and making connections.
