believe it or not, most foreclosures and short sales are not at rock bottom prices as are the resales and if you look hard you will see that for the most part the foreclosed and short sales have no better savings than the resales at this time. Put on top of that the fact that foreclosed and short sale homes are sold as is and that most resale owners are willing to fix items you find wrong, the resales seem to be the better deal
In the past 6 months, these REO (bank owned) properties have sold, you can probabaly import the data to excel if you want to get an "average" or median but this will give a good picture that normally bank owned sell at, above or very near to the asking.
We would be happy to provide you a detailed analysis, but I am pretty confident that you will find there will not be a large difference between the list vs. selling price. In some cases, it may be that the property would sell for over the list price in the event of multiple offers and such. Please let us know if we can assist you further.
It would be easy to find that by asking a local Realtor in that MLS area. They can look up bank owned homes and see what they sold for. I think you will find that the numbers come up 3 to 5% below list to above the listed price which surprises some people who thing they will see huge discounts. The homes are discounted when listed so the banks don't come off the price all that much more and often buyers see a good deal even above listed price. We don't tract home prices that go to courthouse steps auctions if that is what you meant buy "In Foreclosed".
