go to foreclosure.com to check for the nod, it lists the name in the preforeclosure tab and you can sort by street or name to make it quicker, but they lag in posting and the county doesn’t. Riverside county has grantee searches online for free that will tell you when the nod was, 90 days later, almost to the day will be the not, 30 days later will be the sale. check on the sd county website for grantee searches, don’t trust the landlord for dates. Worce case scenario is you have to make a personal visit to the recorders office at 1600 pacific coast highway, nods and nots are public record and they have to be recorded.
The best advice is what Padre said, give notice and indicate that your deposit will be your last month’s rent because you can’t be sure of getting it back since he is in default, don’t try to get anything for free but protect yourself from losing anything.
