In the 10 or so real estate deals that I have done over the past few years, I have to say that the realtor (even the exceptionally good ones) never pointed out any of the nuances of the perils related to the entities you mentioned above. In all cases, it was me, due to bad past experiences with HOAs for example, who was proactively demanding that I be given the HOA restrictions before making the contract; there were plenty of deals I walked away from when I thought the HOA was power hungry and ridiculous. EDIT: I am not dismissing the role of realtors - they had good tips that I use to this day. Here is one: start the homeowner's insurance purchase/quotes during the option period to ensure that any related surprises here will enable you to walk away during the option period than trying to deal with killing the deal with the much-higher earnest money amount at stake. I have to say that the most insightful article I have ever read about realtors came from the controversial Freakonomics. It clearly outlined the separation of concerns and interests and made it clear to me that if a real estate deal is to work well, the only person responsible is me and me alone.
