I don't simply guess about anything pertaining to the law.  I read Lien and Foreclosure Rules sometime ago and I'll see if I can locate the information and get it to you.  I believe after a Homestead Exemption, if the primary residence state has one, and that varies from state to state, a lien may be placed on any other property (primary residences) after any mortgages and in order of receipt by the Courts of liens or judgments by a creditor.
