This one never reached the math. What stopped it is below.

94590 · North Bay

The listing states the per dwelling mix: the front building holds an extra large 2 bedroom house and a 1 bedroom unit, and the back building holds two 2 bedroom units. The run read the mix as unstated and split the 8 bedrooms evenly as 2+2+2+2, pricing four 2 bedroom dwellings.Re derived at the stated mix, with the 1 bedroom unit priced at the 94590 1 bedroom band, the cautious case loses to the index at a breakeven of 9.2 years, so this row does not beat renting and index funds.

  • Re derived at the stated mix, with the 1 bedroom unit priced at the 94590 1 bedroom band, the cautious case loses to the index at a breakeven of 9.2 years, so this row does not beat renting and index funds.

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 Solano County (41 windows), each one swapping its actual price path in for our modeled appreciation.

History replayYearsEnds vs the never-buy path
Worst window1989→1999−$462,162
Median window1999→2009+$310,632
Best window1996→2006+$1,697,330

13 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 $687,099 behind the never-buy path; the deepest point comes in year 7, $731,098 behind.

These windows track Solano County as a whole. Within the county, individual ZIPs' realized 10-year outcomes typically differed from the county's by about ±0.6 points/yr — one zip-decade in ten differed by ±2.2 points/yr or more, and the largest gap since 1977 was 3.7 points/yr. A specific building varies more than its ZIP, not less.

Where these numbers come from

Of the 10 inputs behind this analysis, 5 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: an unclassified source · no independent witness
  • 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.
