My son did not pay loan which i signed for and they repoed his vehicle. i did not put up my property or anything so can they still put lien on my house? appreciate any answers

Depends on what you signed, read your agreement. however, you are liable, and will be until the outstanding debt is paid. it is not going to go away, and it is not going to shrink.they can theoretically put a lien on your assets, any and all of them. they cannot repossess the house, because, as mark_200 points out, your mortgage holder has first dibs.
