Market Analysis for Manchester, NH

[Monica Kovalsky]

Hi all,

I've started investing (buy and hold) in Manchester, NH with multi-family units in a low income area.  I would like to continue doing so but first want to do some due diligence on the market.  I've never done any sort of market analysis or know where to go to find job growth/population data.  If anyone could offer some guidance on how to do the analysis or where to look for data, it would be very much appreciated!  

Much thanks!
