Use a buyer's agent that knows the market, contracts, negotiations, etc.If you really want to learn about investing, get a job in property management. 

Meanwhile, I have 10 units management experience. 

My basic underwriting making some standard assumptions on HOA expenses, 20% down, 7% interest rate, 30 year mortgage, utilities, supplies, and maintenance costs shows a loss of about $22k per year if you are self managing.

Talk to property managers and see if they would manage the other units.

Start by being actively involved with your PROPERTY MANAGEMENT duties.  

I also recommend you start looking for a professional property manager, at least until you educate yourself enough to run this solo.

@Anthony Zotto - By the way you ask the question I assume you're going to self manage the property instead of using a property manager.

thanks for your time and help 1st off, full disclosure here, Rent To Retirement advertises their properties on my Investment Properties For Sale Show, so I am not a totally unbiased opinion and it's only fair that I tell you this up frontHaving said that, outside of running my show for people like them, I also own a property management company in Northeast Ohio and have worked with 1,000's of out of state investors over the years.I say all of that to say this, the overwhelming majority of negative reviews I have seen on them are very similar to a lot of negative experiences investors have with my property management company and others like it that I've worked with.

I would try and manage it yourself if you have the time and effort. 

If you ever need help running numbers or managing your property.
