looking for re-financing a duplex in Pearland

[Qingli Ma]

Hi

I am new into multi family investing. I am looking at a listing: http://www.loopnet.com/Listing/3000-E-49th-St-Kans.... It is listed at $ 2, 700, 000 while being rented for $ 42, 600 per month. This looks nice to me.

What do you think? Any other measures you would use to evaluate? How is the area in Kansas city? 

Appreciated if you can let me know the pro and cons for this property in your mind.
