Going North the Black Diamond meeting in Waltham is great (2nd location in Worcester).  

White text on a black background is harder to read for the human eye than black text on a white background.

He hates black people. 

The map turns sharply from orange to blue around Camden, where the difference between white and black communities seems almost like it has a distinct boundary.In Lakewood, the fastest growing municipality in the state, the town's exploding and largely white Jewish population appears to have settled in an entirely different portion of town than the Hispanic and African American populations.The map was developed using a cartographic interpretation of the 2010 decennial Census -- the most robust dataset available to analyze the changing tides of population in the United States.The data was derived from Census race data parsed down to the Census block level, which typically span only a few municipal blocks in most areas.

Ex: $500/mo rent x 74%$370 x 60 = $22,200 offer price.I think it might be a good rule of thumb but it seems a little black and white for analyzing every deal.

Going a little north there is a the NH Mastermind in Nashua and heading south I'd highly recommend the Black Diamond meeting in Waltham (Alternates every other month with their Worcester location, this is a Waltham month).  

The different colors of mold range from white to black, including, but not limited to, green, gray, brown, orange, yellow and other colors.

What @Todd Plambeck said, except also wanted to add that for master bedrooms, I pick up clearance black-out curtains, nice quality machine-washable fabric, neutral styles, with the white backing (for usual HOA requirements) and on-sale hardware and install them myself.
