I asked for a list of NODs (Notice of Default) at the county Assessor’s office and they charge $0.20 per address/name on the list. I think it cost $20 for a list with 400 names on it.
Could you hire a local college kid part time to spend their time to do the research for you? You’re buying OPT (other people’s time) since your time is more valuable and better spent on other tasks.
