Also if you choose NOT to get a professional to at least look at it, call your local fire department (not by 911, duh) and ask if someone will come over and take a look at it. They could tell you if it is sound or not. Our fire department asks the people of the town to just because we would rather go and visit when it's a calm situation, not when it's a signal 99 and the house is completely aflame.
Brooklyn, Queens, Manhattan, Staten, Uptown, what now? Lets make it happen.
