There are several reasons why this could have happened. The most logical reason would be if at one time there could have been one home on all three of those lots and it was developed and subdivided at a later date... they may have had no choice but to add the "A" to give it a legitimate mailing address. If I knew the exact address including the street I may be able to give you a more definitive answer. It may take a little getting used to, but I wouldn't worry about it.
The real legal address of the property is the block and lot number.
Good luck with your purchase!

The addresses you describe are typical for Brooklyn. How New York City arrived at the address designation is as esoteric as Brooklyn properties addressed as 3209 but in Queens a similar address would be 32-09. Go figure.
Bottom line: if you are purchasing this property be sure your attorney and your Mortgage Banker know the exact address of the property. Double-check all documents throughout the transaction; people make typo's and leave off the "A." Especially if you're working with an out of state mortgage lender you must take extreme care of the address designation on your documents.
