I'm starting to research what is involved in tax sales. One town I checked into stated the following: "If the delinquent property goes into the sale, a lien is placed against the property. If an outside buyer picks up the lien, he must hold it for two years from the date of sale before starting the foreclosure proceedings." It sounds to me like you can't do anything with the property for 2 years. Any further insight to this? Is this common practice?
