Renting vs. Buying in San Diego: The Real Math

"Should I rent or buy?" is the most common question I get from people moving to San Diego or considering their next step. The internet is full of opinions. Let's skip the opinions and look at the actual math.

The Numbers: Renting in San Diego (2026)

Average rent for a 1-bedroom apartment: **$2,400/month**. Average rent for a 2-bedroom: **$3,100/month**. Average rent for a 3-bedroom house: **$3,800/month**. That's $28,800 to $45,600 per year that goes to your landlord and builds zero equity.

The Numbers: Buying in San Diego (2026)

Let's say you buy a $700,000 condo (below median, realistic for a first purchase). With 10% down ($70,000) and a 6.5% mortgage rate:

**Monthly mortgage (P&I):** ~$3,980. **Property tax:** ~$640/month. **HOA:** ~$350/month. **Insurance:** ~$100/month. **Total monthly cost:** ~$5,070.

That's significantly more than renting a 2-bedroom. But here's what the raw numbers don't tell you.

What Renters Miss: The Hidden Math

Equity buildup: Of that $3,980 mortgage payment, roughly $1,350/month goes to principal in year one. That's money you're paying yourself — it's savings, not an expense. By year 5, you've built approximately $90,000 in equity from payments alone.

**Appreciation:** San Diego home values have averaged 5–7% annual appreciation over the last decade. On a $700K home, even 4% appreciation adds $28,000 in year one. That's not guaranteed, but the long-term trend in San Diego is consistently upward.

**Tax benefits:** Mortgage interest and property taxes are deductible. On a $630K mortgage at 6.5%, you're paying ~$40,000 in interest in year one. If you itemize, that's a significant deduction.

**Inflation hedge:** Your mortgage payment is fixed for 30 years. Your rent increases every year. In 10 years, that $3,100 rent could be $4,500+. Your mortgage stays the same.

When Renting Makes More Sense

Buying isn't always better. Renting wins when:

**You're staying less than 3–4 years.** Transaction costs (closing costs, agent commissions, transfer taxes) eat into gains on short holds. If you might move in 2 years, rent.

**You don't have a down payment saved.** Stretching for a home you can barely afford is worse than renting comfortably. Build your savings first.

**You're new to San Diego.** Rent for 6–12 months to learn the neighborhoods before you commit. Living in Pacific Beach is very different from living in Scripps Ranch.

You need maximum flexibility. Job uncertainty, relationship changes, or life transitions — renting gives you the freedom to pivot without a 6-month selling process.

When Buying Makes More Sense

**You're staying 4+ years.** The math starts working in your favor around year 3–4, and gets dramatically better by year 5–7.

**You have 10–20% for a down payment.** This avoids PMI (private mortgage insurance) and gives you better loan terms.

**You want stability.** No landlord raising rent, no lease non-renewals, no moving every 2 years. Your home is yours.

**You see it as a long-term investment.** San Diego isn't getting less desirable. The supply of land is finite (ocean on one side, mountains on the other, Mexico to the south). Long-term demand fundamentals are strong.

The Break-Even Calculation

Here's a simplified way to think about it: take the difference between your monthly buy cost and your monthly rent, multiply by 12, and compare to annual appreciation + equity buildup. If buying costs $1,500/month more than renting ($18,000/year) but you gain $28,000 in appreciation and $16,000 in equity — you're $26,000 ahead by buying.

My Take

For most people who plan to stay in San Diego for 4+ years and can afford a reasonable down payment — buying is the better financial move. But finances are personal. If buying would stress you out, drain your savings, or tie you to a location you're not sure about — rent, save, and buy when you're ready. There's no shame in renting strategically.
