This one never reached the math. What stopped it is below.
95407 · North Bay
The 95407 rent research states an absence for the 2 bedroom dwelling class and instructs that it must not be underwritten, so this row has no admissible rent basis. The run priced its three 2 bedroom units off the whole home 2 bedroom band, which is a different property class.run-sensitivity refused the derivation on the rent stack gate, so no scenario for this row was produced this week.

If the market turns
Modeled appreciation is an assumption, so we replayed this deal against history: every 10-year window in the federal house-price index for Sonoma County (41 windows), each one swapping its actual price path in for our modeled appreciation.
| History replay | Years | Ends vs the never-buy path |
|---|---|---|
| Worst window | 2005→2015 | +$80,034 |
| Median window | 1999→2009 | +$723,483 |
| Best window | 1996→2006 | +$1,710,271 |
None of the 41 windows ended behind the never-buy path.
Replay the 2008 crash as it hit this area and the deal ends year 10 $331,382 behind the never-buy path; the deepest point comes in year 6, $514,094 behind.
These windows track Sonoma County as a whole. Within the county, individual ZIPs' realized 10-year outcomes typically differed from the county's by about ±0.3 points/yr — one zip-decade in ten differed by ±0.8 points/yr or more, and the largest gap since 1975 was 2.1 points/yr. A specific building varies more than its ZIP, not less.
Where these numbers come from
Of the 10 inputs behind this analysis, 6 trace to evidence (our listing feed, area comps, county records); 2 are standing conventions; 1 is derived from other inputs.
- Purchase price: our listing feed · corroborated
- Rent while you live in one unit: area rent comps and research bands · single source
- Rent after you move out: area rent comps and research bands · single source
- The rent you would pay on the never-buy path: area rent comps and research bands · single source
- Property tax rate: local rent regulation · single source
- Unit count: our listing feed · corroborated
A standing convention is a deliberate modeling choice we apply to every deal. We flag it rather than dress it up as evidence.
What we could not verify
- The verdict: we never had enough on this property to run the numbers, so there is nothing here to set against the S&P, and nothing to re-run with your own figures.
