What this means for you Summary
Snapshot
- This is a 10 × 6-bed/6.0-bath units multifamily listed at $2.29M.
Deal economics
- At list price, monthly cash flow is $9k ($107k/yr) — positive. Per door: $889/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($29k rent vs $2.29M).
- Recommended offer: $2.02M (12.0% below list) — sets the bar for market timing.
- Cap rate 10.9% vs local median 2.0% in San Diego — 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 75/100 on livability (#123 in CA, #4,206 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, employment A+; Watch: health & safety C-, crime D+, cost of living F.
- San Diego Unified (urban): math 19% / reading 29% proficiency, ranked #393 of 517 in CA (top 76%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover.
- Market conditions: Rents rising (+2.6%/yr); 120 active listings in the ZIP; 11,759 units permitted in San Diego County in 2024 (7,244 in 5+ unit buildings).
- At $29,154/mo this rent would consume 510% of the median local household income ($69k/yr) (locally 4800% 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 $16k of loan paydown is wiped out by about $69k of value loss. Plan a longer hold.
- San Diego County population projected at +20% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
- At projected returns (-3.0% appreciation + 2.6% rent growth), your $643k cash investment doubles in ~8 years — after that, you're playing with house money.
Negotiation context
- It's been on market 154 days — a 12% lower offer ($2.02M) is reasonable based on typical stale-listing flexibility.
- 2 sale attempts; this cycle's ask has dropped $200k (8%) from the opening price — seller is motivated, your offer sets the floor, not the list.
- Current owner paid $760k; list at $2.29M implies a 202% gain — meaningful room to come down on a strong offer.
Questions for the listing agent
- It's been on market 154 days. Have you received any prior offers? Is the seller open to a 12% 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 1976 — 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.
- Schools are B-rated — typically a magnet for longer-tenancy family renters. What's the average tenant stay here, and is there a school-zone premium baked into asking?
- Crime grade is D 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?
- 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.
