What this means for you Summary

Snapshot

  • This is a 2 × 3-bed/1.0-bath units multifamily listed at $590k.

Deal economics

  • At list price, monthly cash flow is $165 ($2k/yr) — positive. Per door: $82/mo.
  • The deal already cash-flows at list — no discount required.
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $504k (14.6% below list).
  • Recommended offer: $504k (14.6% below list) — sets the bar for 1% rule.
  • Cap rate 6.6% vs local median 2.5% in Oakland — 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 71/100 on livability (#224 in CA) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, employment A+; Watch: crime F, cost of living F.
  • Oakland Unified (urban): math 27% / reading 33% proficiency, ranked #1,007 of 1,400 in CA (top 72%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases; 68% free/reduced lunch — lower-income household profile, screen leases tightly.
  • Zoned schools: Melrose Leadership Academy (656 students, 47% FRL); Frick United Academy of Language Middle (334 students, 98% FRL); Castlemont High (680 students, 98% FRL).
  • Market conditions: Rents flat; 187 active listings in the ZIP; 16 comparable units currently listed for rent nearby; rentals lingering (median 46d on market — plan ~5-8 weeks vacancy on turnover, expect pricing pressure); 69% of comp listings sitting > 30 days — soft ceiling on asking rent; solid renter incomes; 1,742 units permitted in Alameda County in 2024 (856 in 5+ unit buildings).
  • At $5,036/mo this rent would consume 57% of the median local household income ($106k/yr) (locally 2086% 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 $4k of loan paydown is wiped out by about $18k of value loss. Plan a longer hold.
  • Alameda County population projected at +34% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.

Negotiation context

  • Only 8 days on market — expect competitive offers; lowballing is unlikely to land.
  • 4 sale attempts since 19y ago with the ask held roughly flat each time — persistent listings suggest the price (not the market) is what's stuck; bring a comps-based counter.
  • Current owner paid $184k; list at $590k implies a 221% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: built in 1948 — expect roof / HVAC / electrical / plumbing capex.
Recommended offer $503,600 (14.6% below list)

Questions for the listing agent

  1. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
  2. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
  3. Built in 1948 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  5. 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?
  6. 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?
  7. 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.
  8. 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.
  9. 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.
