I have noticed during discussions on Bp. This is all hypothetical, someone will say they have a property for sale. Another person will reply back and ask what type of area is this property in. The seller will respond it is in an A area or a C area. I have seen A,B,C and D classifications.

Finally the question,  are these ratings just opinion or is there a place to find the data to back up these neighborhood classifications.  Thank You.  Jim Holmes
