Margin is vs. investing the same money in the S&P 500; the S&P breakeven is the yearly stock return that would tie it, and the crash floor is the yearly appreciation below which the deal loses. Wealth at year 10 counts home equity at full value; the sold line subtracts selling costs. ## Property facts Asking price $375,000 Units 2 Beds / baths 5 / 2 Square feet 1,710 Year built 1907 Property type Multi-Family Days on market 77 Neighborhood Lower San Antonio / Fairfax flats — interior, near the DTSC Fruitvale brownfield remediation Strategy lane duplex Nearest catalyst La Clínica de La Raza flagship (1515 Fruitvale Ave) (0.45 mi) Modeled appreciation 4.0%/yr Unit count verified: 2 units, corroborated by county assessor records and the listing itself. duplex — Lower San Antonio / Fairfax flats — interior, near the DTSC Fruitvale brownfield remediation · 0.45 mi from La Clínica de La Raza flagship (1515 Fruitvale Ave).

History replay Years Ends vs the never-buy path Worst window 2002→2012 +$119,746 Median window 1992→2002 +$374,824 Best window 1996→2006 +$875,026 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 $22,835 behind the never-buy path; the deepest point comes in year 6, $140,666 behind. These windows track Alameda County as a whole. Within the county, individual ZIPs' realized 10-year outcomes typically differed from the county's by about ±1.2 points/yr — one zip-decade in ten differed by ±3.5 points/yr or more, and the largest gap since 1975 was 5.5 points/yr. A specific building varies more than its ZIP, not less. ## Where these numbers come from Of the 12 inputs behind this analysis, 4 trace to evidence (our listing feed, area comps, county records); 4 are standing conventions; 3 are derived from other inputs. - **Purchase price**: our listing feed · sources disagree - **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**: area rent comps and research bands · single source - **Property tax rate**: local rent regulation · single source - **Unit count**: county assessor records · corroborated A standing convention is a deliberate modeling choice we apply to every deal.
