Hi Anil KumarThese are the two that I have attended:http://www.meetup.com/Black-Diamond-Real-Estate-Investors-Massachusetts/http://www.newenglandreia.com/Hope to see you there!

Any rental property owner should always belong to their local property owners assn, if only for legislative updates and connections in the landlord community.The Worcester Black Diamond is more broad based, and has topics of interest to all kinds of real estate investors.

I would recommend checking out some local networking events such as the Black Diamond event that @Ann Bellamy co-hosts, the AREIA events (there is one in Boston) and you're welcome to come to the next Unofficial BiggerPockets Networkign Event that I'm hosting in Woburn in March.

If you are a fan of nature you might want to check out Black Forrest, and if you plan to split time between the Springs and Denver you should look at Castle Rock, Monument and Palmer Lake.

Being in Waltham you will definitely want to check out the Black Diamond meeting in town.  

Go to Vegas and bet on black... you can double your money with the spin of a wheel (course you could lose it too, so do your own risk analysis!)

Look, one has to understand the context of when RDPD came out, it was a vastly different world, to put it in terms just remember many television shows were still in black and white at the time, no joke. 

Some folk go for dark (black) which can look striking but it screams "rental unit" in my book. 

If HUD puts you on the "Black List" they will tell you, the letter will say "Don't call us and we won't call on you" LOLSeriously, you will be informed of the restrictions.

The tenant thing is mostly psychology, black magic, and a whole sh!
