Funny! We were going to buy 11 Ruth Ave before we bought this house! As soon as we found out about all of the problems it had during the inspection (especially with the foundation), we bailed . This house then went up for sale a few weeks later and we bought it the day it went on the market! I still can't believe we ended up buying a house on the same street as the first house we were about to buy!
looks like the previous listing agent/company failed to remove it? it may be an old ad.... I would contact Trulia directly as they may not review the questions listed here... or perhaps call the listing agency from when you purchased the home.
I was just on your street reviewing the property at #11? which is bank owned and needs some work prior to sale... small world!
