San Diego occupies a unique California position — coastal access, year-round mild climate, and a diversified economy that doesn't depend on a single industry. The 1.96% cap rate at a $930,000 median price is what California pricing produces in 2026; the 0.31% rent-to-price ratio is materially below 1%, which means cash flow at the median is negative on conventional underwriting. The investment thesis is appreciation, equity paydown, and the cumulative effect of Prop 13's assessment cap over multi-decade holds.
Employment is unusually diversified for California — UC San Diego and the broader biotech cluster in Torrey Pines / La Jolla (Illumina, Qualcomm, hundreds of biotech and medical device firms), the deep Navy and Marine Corps presence (Naval Base San Diego, Camp Pendleton, Coronado), Sharp / Scripps medical systems, and a tourism / hospitality base anchoring service-sector tenant demand. Submarkets vary widely: La Jolla, Del Mar, Solana Beach command top-of-metro pricing. Mission Hills, North Park, Hillcrest, and the urban core offer walkable mid-tier rentals. Chula Vista, El Cajon, and parts of South Bay offer deeper value at the trade-off of longer commutes and tighter tenant pools.
AB 1482 statewide rent cap applies to most properties built before 15 years ago. The City of San Diego doesn't have its own rent stabilization but does have a Tenant Protection Ordinance (just-cause eviction) covering most rentals. Water-scarcity underwriting matters more than most investors model — landscape water budgets, drought restrictions, and the cost of converting irrigation systems affect both expenses and tenant satisfaction. Insurance has tightened post-wildfire repricing across San Diego County, particularly in the eastern foothills and along the urban-wildland interface. San Diego is a long-hold, appreciation-thesis market — underwrite for 10+ year ownership, not flips.

San Diego's 0.3% rent-to-price ratio is well below the 1% rule. At median prices of $930,000, the $2,870/mo rent produces only $1,520/mo in NOI. Investors here need to target below-median properties or pursue value-add strategies to make the numbers work.
At current rates, a 20% down conventional loan ($186K at 7%) would result in approximately $-3,428/mo cash flow — negative at median prices. Larger down payments, seller financing, or buying 15–25% below median are strategies to turn the numbers positive.
Property taxes consume 20% of gross rent here — one of the highest ratios in our dataset. This significantly compresses margins and makes San Diego a market where tax-conscious underwriting is essential. Every deal should be stress-tested with potential assessment increases.
All figures below are computed from San Diego's real market medians. Use them as a baseline; override with property-specific numbers in the calculators.
At 0.75% effective rate on the $930,000 median price, the annual tax bill is $6,975 — that's below national average (-29% vs the national average of ~1.06%). Verify the actual assessed value before purchase; sale-triggered reassessments can push the bill higher than the seller's current statement.
If San Diego continues appreciating at 2.8%/yr while rents grow at a conservative 3%/yr, cap rate holds roughly steady as price growth outpaces rent. Year-by-year projection at the median:
| Year | Est. Price | Est. Rent/Mo | Cap Rate |
|---|---|---|---|
| Today | $930K | $2,870 | 2.0% |
| Year 1 | $956K | $2,956 | 2.0% |
| Year 2 | $983K | $3,045 | 2.0% |
| Year 3 | $1.0M | $3,136 | 2.0% |
| Year 4 | $1.0M | $3,230 | 2.0% |
| Year 5 | $1.1M | $3,327 | 2.0% |
Same median-priced San Diego property — different capital structures. All-cash maximizes cap rate. Leverage trades cash flow for higher cash-on-cash return when the spread between cap rate and borrowing cost is positive.
| Scenario | Cash Invested | Monthly Cash Flow | Annual CF | Cash-on-Cash |
|---|---|---|---|---|
| All cash | $930K | $1,520 | $18,234 | 2.0% |
| 20% down conventional @ 7% | $214K | $-3,428 | $-41,137 | -19.2% |
| 25% down DSCR @ 8.5% | $270K | $-3,844 | $-46,131 | -17.1% |
Properties don't always trade at the median. Lower-priced units typically offer higher cap rates but harder operations; higher-priced properties tend to compress cap rates while attracting better tenants. All-cash assumptions below:
| Tier | Price | Rent/Mo | NOI/Yr | Cap Rate | Monthly CF |
|---|---|---|---|---|---|
| Below median (~75% price) | $698K | $2,440 | $15,051 | 2.2% | $1,254 |
| At median | $930K | $2,870 | $16,444 | 1.8% | $1,370 |
| Above median (~125% price) | $1.2M | $3,300 | $17,836 | 1.5% | $1,486 |
Cap rate is just one piece. Real estate returns come from four sources: cash flow, appreciation, principal paydown, and tax benefits. Assuming 20% down conventional financing at 7% and a 5-year hold at San Diego's historical appreciation rate of 2.8%:
On a $186K down payment, that's a -6.6% total ROI over 5 years (not annualized). Tax benefits from depreciation are additional and depend on your personal tax bracket.

San Diego, CA has a population of 50,000 and has been growing at 0.8% annually — roughly in line with national trends, meaning demand is stable but not exceptional. The median home price of $930,000 paired with median rents of $2,870/mo produces an estimated cap rate of 1.96%.
Property taxes at 0.75% are well below the national average of ~1.1%, providing a meaningful cash flow advantage many investors overlook. The vacancy rate of 5.2% is moderate and within normal parameters for a healthy rental market.
At a price-to-income ratio of 15.5x, homes cost about 15.5 times the local median income of $60,018. This elevated ratio means homeownership is stretched, supporting rental demand but limiting buyer pools. Home values have appreciated at roughly 2.8% annually. Steady appreciation means total returns will be primarily cash flow-driven — the more sustainable model for long-term wealth building.
Bottom line: At current median prices, San Diego is challenging for pure cash flow investing. Consider BRRRR strategies with below-market purchases, or look at neighboring metros with stronger price-to-rent ratios.
