House hacking advice

[Hiro Kitagawa]

Hi all, my name is Hiro and am a fairly new BP member from Cincinnati OH area.  A bit about me, I purchased my first property roughly a year ago which I'm currently renting out.  I bought it without knowing much other than wanting to invest.  

I'm now looking into house hacking a triplex in a fairly rebuilt part of the city, and would much appreciate you all's insights.  The property is on sale for $200K, on a street among $170K - $350K houses.  Below are some bullet points:

• On sale for $200K
• Built 1906 (normal for this area)
• Three family home
• Last sold 2011 for $118K
• Rental income in the area for 2BDR (same as what each unit has in this building) is approx. $900 - $1,100
• Based on $900 x 3 units (if I don't reside) / 8% vacancy / 5% maintenance / 10% cap-ex / 8% property management fee, cash flow calculates to be approx. $450/mo.

I will go see the inside this week with my realtor and handyman.  Before I do, what are some key points I should be looking for, or consider?
