I always tend to be a bit suspicious when a house is listed without a specific address. Why would you do that if it is 'for real' and your real desire is to sell that house?
It has historically been a bait-and-switch kind of tactic. Get you to call on the unbelievable deal, and then try to sell you another because that one is no longer available.
You can find some great prices on 'real deals'. There are savy sellers out there (including bank-owned) that are realizing that putting a price below even today's current values will bring the most buyers to their property (which is critical when there is such a large inventory. The buyers themselves are more knoweldgable than ever before, and will overbid the property up in line with current values. Thus, the properties that are priced correctly in today's market sell quickly. I believe I noticed the listing your inquired about showed being on the market for over 30 days. That would not happen if it were 'for real'.
I do firmly believe that in todays market it is more important than ever to have a Professional Realtor in your corner. With the assortment of Bank-Owned homes, Short Sales, HUD Repos, along with reqular sales and unrealistic come-ons, a realtor can assist you in finding the real and best prices and home for you. Remember, a realtor representing you, the buyer, is PAID BY THE SELLER at closing, not you. You, the buyer, have the opportunity to have a wealth of information, knowledge, and assistance at your fingertips at no cost to you!
Good luck to you, and please don't hesitate to contact me if you have any questions.
