I would cut your teeth on a Duplex, Triplex or Quad first, get experience managing and landlording, then venture into a small commercial investment.  

All that stated, however, if as @Ofelia Flores has suggested, she is a good tenant who pays her rent on time and takes care of the property why kick a gift horse in the teeth.

But it has been my experience over the years that people will lie thru their teeth and will screw thier fellow man/woman over in a second if they think it will benefit them.  

http://nreig.com/I'll post a longer thread about my investment goals - but the quick version.Cut my teeth on two investment properties here in the Bay Area, got great purchase prices in 2010 and 2013. 

If you can cut your teeth by hooking up with some local Oahu investors, you can make some cash, learn a ton, and probably find a deal or two near you.

Congrats what a great one to cut your teeth on. 28k and 770.00 a month thats a real nice ROI.

Start with SFRs and cut your teeth there. 

In fact, I told my broker last week, this is a distressed property without a distressed price tag.But you are exactly hitting on my two big reservations: 1) overvalued relative to age/condition and rent roll, and maintenance problems, 2) and this is probably a bad way to cut my teeth...too much for first time deal.It's just easy to get blindsided by the apparent, as-is cash flow.

I need to cut my teeth on.

Some "deals" don't have the teeth I need to pull the trigger on so I will pass them on to less active (less needy) investors.
