The appraised value at the Sheriff sale is frequently not an accurate representation of the value of the property. They are drive-by appraisals and frequently appear to be influenced by the judgement amount so I take the number with a (very small) grain of salt.
That being said, the property will not, under any circumstance, be sold for less than 2/3 of the appraised value. That is Oklahoma law.
The "No Bid / No Sale" occurs when the bank does not enter a bid and there are no other bidders willing to pay 2/3 of the appraised value. The property simply rolls to another auction to attempt the sale again.
I believe the plaintiff can petition for a new appraisal if they feel the appraised value is too high and preventing the property from selling.
Several years ago I spoke with a plaintiffs attorney regarding a property I was interested in and told them the appraised value was much too high for any investor to pay 2/3. It had no bid for a few auctions and then suddenly the court case showed the property was re-appraised for a lower amount. I then bid and purchased the property. I'm assuming the plaintiff (bank's attorney) had asked for a new appraisal to be conducted.
If you have additional specific questions regarding the process, the best source of information is the sheriff's office civil desk (918-596-5684, [email protected]) or to ask the plaintiff's attorney directly. I have found both to usually be very friendly and willing to answer questions regarding the process.
