I should explain the process for you, since Im very familiar with it.
Notice of default is filed when the lender feels they are due their payments. Typically 120 days after not receiving payments, but can be as soon as 31 days after not receiving their payments (Technically, they can file on the 2nd day of the month if payments are due on the 1st) But I digress.
NOD is filed - 90 day window before NTS (Notice of Trustee Sale)
Once the NTS is filed, it will have to be published in a public viewing area, typically in a local paper, for 3 weeks before holding the auction.
So, from the time you are current, to the time you will be kicked out of the home, in a perfect scenario, would be 90 days of non payment, 90 days of notice of default, then 21 days of notice trustee sale, then sherrif shows up at your door on day 22.
