If one owner out of six refuses to sign, any of the others can sue for "partition," which is an action to divide the property. It probably can't be divided up six ways, so the court would order it sold. If we are talking about heirs, this would mean that six people are entitled to a share of the owner's estate. The owner's personal representative can sell the house, and does not need the approval of the heirs (although an heir could object that the sale was not for sufficient value, or was defective in some other way).
