By understanding these factors, you’ll see why San Jose ranks among America’s least affordable cities—and how to make smarter real estate decisions here.

1. Sky‑High Housing Prices & Trends

• Median Home Price (2025): $1,450,000

• Year‑Over‑Year Change: +1.2% despite broader market cool‑off.

• Condo vs. House: Condos average $1.1 M; single‑family homes $1.6 M.

Key Point: Years of rapid appreciation outpaced wages, creating a steep entry barrier for first‑time buyers.

2. Supply Constraints & Strict Zoning

2.1 Limited Land Availability

• San Jose is bounded by hills and bay; only ~7% open land remains.

• New Construction (2024): Permits down 12% YOY .

2.2 Restrictive Zoning & Height Limits

• Most areas zoned for single‑family homes only.

• Multi‑unit developments face lengthy approval and community pushback (“NIMBYism”).

Impact: Low housing starts fail to meet demand, keeping prices elevated.

3. Tech‑Sector Income Dynamics

• Median Household Income: $135,000 vs. U.S. $70,000 .

• High‑Pay Roles: Software engineers often start above $150,000.

Consequence: Higher incomes fuel higher prices—wealth begets wealth in real estate markets.

4. Rent & Rental Demand

• Vacancy Rate: ~3% (tight)

• Investor Activity: High yields (~5% cap rates) attract landlords, limiting availability for long‑term renters.

Result: Renters face steep monthly costs and fierce competition.

5. High Taxes & Carrying Costs

• Total Ownership Carrying: ~2%–3% of home value annually.

Takeaway: Even after mortgage, taxes and fees add a heavy financial load.

6. ADUs & Buyer Assistance Programs

6.1 ADU Opportunities

• Permit + Impact Fees: $8K–$15K

• Build Cost: $300+ per sq ft

• Rental Income: $2,200–$2,700/mo

6.2 Buyer Programs

• CalHFA Grants: Up to $45,000

• City Forgivable Loans: $50,000

• Mortgage Tax Credits: 20% of interest

Strategy: Combine ADU income and grants to offset high entry costs by up to $95K.

7. Neighborhood Variations

Insight: While all are pricey, areas like Berryessa offer relative value—but still cost well above national norms.

8. Strategies to Cope with Unaffordability

1. Leverage Buyer Programs: Apply for grants and forgivable loans early.

2. Consider ADU Development: Boost income and equity.

3. Expand Search Radius: Look at Milpitas or South SJ for lower entry prices.

4. Lock In Rates: Paying points can reduce your long‑term mortgage expense.

5. Partner Investing: Pool resources with family or investors for down payment.

Final Tip: Get pre‑approved, set a firm budget, and work with a hyperlocal realtor who knows hidden opportunities.

Conclusion

San Jose’s unaffordability stems from limited supply, high incomes, steep taxes, and zoning constraints, all amplified by relentless tech demand. Median home prices near $1.45 M, rents above $3,200, and carrying costs around 2%–3% annually make it one of America’s toughest markets.

However, strategic use of ADUs, buyer assistance, and targeted neighborhood choices can help you take your first step into this dynamic market. With careful planning and the right local expertise from Block Change Real Estate, owning or investing in San Jose becomes a realistic goal—even in 2025.
