What's up with all of these overpriced homes?!?!

I had appointments to show about 8 homes the other day with a client of mine who is looking in the $165,000 to $175,000 price range. He was really excited to head out and was extremely optimistic about finding a home that day... UNTIL... we saw about 3 of the 8 homes and realized how overpriced they were!!! I couldn't believe that these homes have been at their current prices for so long without a price adjustment... Sellers really need to understand that this market is flooded with listings and if your home isn't priced aggressively, buyers will pass on by... The only way sellers will realize this is if we, agents, have REAL conversations with our clients about pricing?!
