I largely agree with @Ron S. The 'go-to' place for a trustee state like NC is 1) the county courthouse, and 2) the trustee's web sites. Trustees like Brock and Scott provide details on their open cases and the upset bid status. 10-15 years ago, they had 10X the foreclosure cases. For BP readers in NC (or other trustee states), get to know the trustees that operate in your county of choice, then periodically look for upcoming sales. If you go gung-ho, follow substitute trustee (S-TR or equivalent) filings in your county.
Anecdotally, from searching Wake County (WC) NC records, defaults remain at near all-time lows, and I see this market (foreclosure/pre-foreclosure) as an opportunity not worth pursuing. There have been roughly 50 S-TR filings per month for 2H2024, relatively unchanged for 18 months at least.
The only thing interesting in 2024 WC defaults is the vintage year, which is over 35% 2021-2022, meaning a lot of recent borrowers threw in the towel in short order (no pun intended). The number of defaults is too small to worry about, at least today. We need a significant retail price correction as a catalyst to change that, in WC at least.
