What this means for you Summary
Snapshot
- This is a 3 × 3-bed/3.0-bath units multifamily listed at $675k.
Deal economics
- At list price, monthly cash flow is $1k ($14k/yr) — positive. Per door: $402/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($7k rent vs $675k).
- Recommended offer: $614k (9.0% below list) — sets the bar for market timing.
- Cap rate 8.4% vs local median 2.1% in Guerneville — 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 59/100 on livability (#666 in CA) — a working-class tenant base; expect higher turnover. Strengths: crime A-, employment B; Watch: health & safety D, amenities F, commute F.
- West Sonoma County Union High (suburban): math 43% / reading 56% proficiency, ranked #143 of 517 in CA (top 28%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
- Market conditions: 82 active listings in the ZIP; 1 comparable units currently listed for rent nearby; solid renter incomes; 1,039 units permitted in Sonoma County in 2024 (185 in 5+ unit buildings).
- At $7,295/mo this rent would consume 102% of the median local household income ($86k/yr) (locally 242% 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 $5k of loan paydown is wiped out by about $20k of value loss. Plan a longer hold.
- Sonoma County population projected at +8% by 2050 — modest demand growth; plan on rents tracking national, not racing it.
Negotiation context
- It's been on market 108 days — a 9% lower offer ($614k) is reasonable based on typical stale-listing flexibility.
- 3 sale attempts since 13y 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 $161k; list at $675k implies a 319% gain — meaningful room to come down on a strong offer.
Risks & watch-outs
- Watch-outs: built in 1923 — expect roof / HVAC / electrical / plumbing capex.
Questions for the listing agent
- It's been on market 108 days. Have you received any prior offers? Is the seller open to a 9% concession, seller financing, or rate buy-down credit?
- 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?
- Built in 1923 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
- Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
- 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.
