A Midwestern couple in their late 60s has done most of the right things: they own their home outright, have accumulated a solid nest egg, and are ready to retire. Their question is one that comes up often among would-be transplants: is it enough to make San Diego work?
Why San Diego Stays at the Top of Every Retirement List
San Diego offers the kind of retirement lifestyle that fills vision boards: year-round mild weather, beaches stretching from La Jolla to Coronado, walkable neighborhoods, top-tier healthcare, a major international airport, and an active community of retirees. The catch is that all of those advantages come with a price tag, and it is one of the highest in the country.
Vacation and Retirement in San Diego Are Different Things
A tourist rents the beach and sunsets for a week. A retiree buys the property tax bill, homeowners insurance, maintenance costs, and a California tax return that follows them into retirement. The same coastline that costs a few hundred dollars a night on vacation can require close to $2 million to own in some of San Diego County’s most desirable communities. The lifestyle is extraordinary, but unlike a vacation, the bills arrive every month whether you spend the day at the beach or not.
What the Three Real Scenarios Cost
Start with the household: Social Security of $48,000 a year, a $450,000 paid-off Midwest home, and the rest in a retirement portfolio. Medicare runs Medicare Part B in 2026 runs $202.90 a month per person at the standard tier, roughly $4,900 a year for the couple. California fully exempts Social Security from state income tax, but every dollar pulled from a traditional IRA or 401(k) is taxed as ordinary income at rates that climb fast, reshaping every scenario below.
The Coastal Dream (Carlsbad, Encinitas, Coronado). Buying near the water at roughly $1.6 million takes the $450,000 of Midwest equity and another $1.15 million from the portfolio at closing. Property tax under Prop 13 starts near 1.1% of purchase price, roughly $17,600 a year, locked to that basis for life. San Diego homeowners insurance averages around $1,770 for standard coverage, though coastal and wildfire-adjacent ZIPs often run multiples of that. Add utilities, HOA, food, healthcare, transportation, and reserves, and an honest annual budget lands near $115,000 to $125,000.
The Practical Inland Retirement (Escondido, Poway, Rancho Bernardo). A comparable single-family home in Rancho Bernardo trades near a $890,000 median. Property tax drops to roughly $9,800, insurance eases, and the beach is a 25 to 40 minute drive. The same lifestyle comes in around $85,000 to $95,000 a year.
Rent, Don’t Buy. Selling the Midwest house, keeping the full portfolio invested, and renting a two-bedroom in a desirable inland neighborhood for roughly $3,400 a month preserves capital and skips the property tax reset. Total annual cost lands near $90,000, with rent inflation tracking above the broader CPI reading of 334.0 in coastal California for most of the past decade.
The Tax Detail Most Calculators Skip
To net $50,000 above Social Security in the inland scenario, the couple must gross up withdrawals for federal tax, California tax at brackets reaching 9.3%, and the Medicare IRMAA surcharge that triggers above $218,000 of joint MAGI. A retiree in Florida pulling the same $50,000 needs about $58,000 gross. In California, that same net is closer to $68,000 to $72,000 gross. At a 4% withdrawal rate, every extra $10,000 of forced gross-up adds $250,000 to the portfolio target. That is the real San Diego tax, hitting the inland retiree as hard as the coastal one.
What It Actually Takes
At a 4% withdrawal rate on a 25 to 30 year horizon, with the 10-year Treasury at 4.56% supporting a reasonable bond sleeve, the inland buy scenario needs the $450,000 Midwest equity plus roughly $1.5 million invested, call it $1.95 million in total assets. The rent scenario needs about $1.6 million invested plus home-sale proceeds in reserve. The coastal dream needs closer to $2.6 million in total assets and accepts insurance fragility. For a middle-class couple with Social Security of $48,000, San Diego is reachable inland, stretched coastal, and most honest as a rental. The dream is real. It costs about a quarter-million more in portfolio than the same life in a no-income-tax state.
