How did you purchase? Did you use a realtor and a title company?
a) Is the address correct?
b) Does it list you as the property owner OR former owner which you can tax roll?
c) Did you complete the transaction via title company? Is the title transferred in your name ? OR did you pay a seller direct without going thru title.
Recommend perhaps contacting bank you provide the notice provide closing documents, also contact title company, confer with attorney
