Thank you all for chiming in.
@Will Sifert, here is a brief description of the foreclosure process in Arizona:
@Chris Brevik, I am not going to ask the county treasurer's staff as I suspect they know the generic stuff (such as waiting three years after the lien on the property was first brought to sale), but not the nuances about whether or not one is allowed to mail notices 6 to 7 weeks before the expiration of the 3 years redemption period.
I have read once in an internet forum than one investor got fined $200 per contact after he sent mass mailing to many owners before the expiration of the redemption period. If I remember correctly, the state was Missouri. Hence my concern and the original question in the forum. But I am only going to contact two homeowners. So, even if that ends up being a seminar for me, it won't be an expensive one.
@Jerry K., I have never actually foreclosed on a tax lien in Arizona. Not on my own. Not using an attorney. But I did follow, in 2020, what you recommended: I had an attorney send out the mailings for two property owners. His assistant sent me copies of the mailings. And I have mastered the Monkey See Monkey Do technique.
I plan to do the mailings for two homeowners ASAP after January 1, 2024. I will update the thread if I find out anything about whether:
A) There is any penalty for contacting the homeowners before the expiration of the redemption period.
B) My lawyer accepts to use my mailing(s) as a starting point.
C) If my lawyer decides to re-do the mailings himself, whether that's because I sent them before the expiration of the redemption period, for another reason, or for both reasons.
