Treat the count as a claim, not a verified fact; every number on this page rides on it.

History replay Years Ends vs the never-buy path Worst window 1989→1999 −$858,565 Median window 1991→2001 +$1,032,338 Best window 1996→2006 +$3,940,339 2 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 $524,641 behind the never-buy path; the deepest point comes in year 7, $942,570 behind. These windows track San Mateo County as a whole. Within the county, individual ZIPs' realized 10-year outcomes typically differed from the county's by about ±0.5 points/yr — one zip-decade in ten differed by ±1.4 points/yr or more, and the largest gap since 1975 was 6.3 points/yr. A specific building varies more than its ZIP, not less. ## Where these numbers come from Of the 10 inputs behind this analysis, 3 trace to evidence (our listing feed, area comps, county records); 2 are standing conventions; 4 are derived from other inputs. - **Purchase price**: our listing feed · corroborated - **Rent while you live in one unit**: derived from other inputs here · single source - **Rent after you move out**: derived from other inputs here · single source - **The rent you would pay on the never-buy path**: derived from other inputs here · single source - **Property tax rate**: our listing feed · single source - **Unit count**: a prior adjudicated ruling · single source 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. Members on a paid plan can request verification. ## Want this for an address you pick?
