Ummmm, that's awkward. What would you say?

I'm sending letters to delinquent tax property owners. I received my first call (yay!). Nice guy and enjoyed chatting. When he asked me how I got his name and address I just said something along the lines of I looked up some properties and saw he'd had it for a long time and wondered if he'd like to sell. Clearly I don't want to embarrass someone by saying "I got your name from the list of people who don't pay their taxes" Anyone have a recommendation? What would you say?
