Townhouse investing? numbers?

[Hina Pasha]

I have invested in single family detached homes in the suburbs before. But recently I have been looking into townhomes in the city and am making an offer on one which is part of a gated community. Are there any drawbacks going into townhomes investing?  Also, i am a bit confused with the numbers and would appreciate any advice from all you seasoned investors.  

It is a 3bed/3.5bath (2000 sq ft) $460000. HOA $2350, Taxes 10K, Insurance 1850. Rent estimate $3200.

Any feedback will be appreciated. Thank you
