We were purchasing a new home in GA and had the floors upgraded to hardwood in one bedroom. We paid $1,450.00 out of pocket, the home didn't appraise, and the deal fell through. This home previously fell through with another buyer due to it also not meeting the appraised value. We feel that we have been knowingly cheated out of an upgrade for the next buyer and the builder is refusing to pay us back. Can we file a lien against the property at this time?
