What this means for you Summary
Snapshot
- This is a 2 × 3-bed/2-bath units multifamily listed at $999k.
Deal economics
- At list price, monthly cash flow is $-1k ($-17k/yr) — negative. Per door: $-691/mo.
- To cash-flow at today's rent, offer at most $755k (24.4% below list).
- To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $735k (26.4% below list).
- Recommended offer: $735k (26.4% below list) — sets the bar for 1% rule.
- Cap rate 4.6% vs local median 1.6% in San Jose — top-decile yield for the area; either an underpriced asset or a hidden risk that comps aren't pricing in. Stress-test before assuming the spread holds.
Location & tenants
- Location reads 78/100 on livability (#68 in CA, #2,559 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, employment A+; Watch: crime F, cost of living F.
- San Jose Unified (urban): math 39% / reading 52% proficiency, ranked #149 of 517 in CA (top 29%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
- Market conditions: Rents rising fast (+4.2%/yr); 104 active listings in the ZIP; 2 comparable units currently listed for rent nearby; solid renter incomes; 3,838 units permitted in Santa Clara County in 2024 (1,886 in 5+ unit buildings).
- At $7,354/mo this rent would consume 99% of the median local household income ($89k/yr) (locally 4364% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.
Forward outlook
- Local home prices are declining (-3.0%/yr); year-one equity from $7k of loan paydown is wiped out by about $30k of value loss. Plan a longer hold.
- Santa Clara County population projected at +24% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
Negotiation context
- Only 13 days on market — expect competitive offers; lowballing is unlikely to land.
Risks & watch-outs
- Climate carrying-cost: extreme-heat days projected 7→14/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Questions for the listing agent
- What do current leases actually rent for vs. the listed asking? Can we see a recent rent roll and the last 12 months of T-12 income?
- Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
- What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
- Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
- Crime grade is F in this area — have there been break-ins, vandalism, or insurance claims at this property in the last 3 years? What carrier currently insures it and at what premium?
- The area grade is low — what's the realistic commute time and amenity access for the typical tenant pool here? Any planned neighborhood developments (good or bad) we should know about?
- What's the average days-on-market for RENTAL listings here right now (not sales)? A rising rental-DOM trend means longer vacancies and softer asking-rent achievability than the comps imply.
- What's the recent tenant-quality profile in this submarket — average credit score on applications, eviction rate, late-payment / NSF rate, and stable-employment percentage? A property-management company in the area should have these aggregated.
- How much new apartment / multifamily construction is in the pipeline within 1–3 miles? Heavy new supply (>2% of stock underway) typically softens rents 12–24 months out; light construction supports rent growth.

For passive investors: Depreciation is non-cash, so a rental often shows a tax loss while cash-flowing — sheltering income. Rental losses are passive: they offset passive income freely, and up to $25,000/yr can offset ordinary (W-2) income if you actively participate and your MAGI is under $100k (phasing out to $0 by $150k); unused losses carry forward. On sale, claimed depreciation is recaptured at up to 25%, and gains may owe capital-gains tax (a 1031 exchange can defer both). Figures are a year-1 estimate at your 24.0% rate — not tax advice; consult a CPA.
