San Francisco vs Austin: Total Homeownership Cost

A $150,000 household income qualifies comfortably for a median home in Austin — and is effectively disqualified from buying the median home in San Francisco. The numbers are that stark: San Francisco’s median home reached $1,350,000 in Q1 2026, per the National Association of Realtors (NAR), while Austin’s came in at $415,300, according to the Austin Board of Realtors Q1 2026 Central Texas Housing Report. That’s a 225% price gap — and the true cost divergence is even wider once taxes, insurance, and ongoing carrying costs enter the calculation.

The Mortgage Math: Where the Gap Starts

The 30-year fixed mortgage rate stood at 6.53% as of May 28, 2026, according to Freddie Mac’s Primary Mortgage Market Survey (PMMS). On a $1,080,000 San Francisco loan (after 20% down), that rate generates a principal and interest payment of $6,848 per month. On Austin’s $332,240 loan, the same rate produces $2,107 per month — a difference of $4,741 every single month, before a single dollar of taxes or insurance is counted.

The down payment gap deserves equal attention. Assembling $270,000 for a San Francisco down payment is a savings challenge that belongs in a different category than Austin’s $83,060 requirement. For a $150k household saving 20% of gross income annually, the San Francisco down payment takes roughly 18 years to accumulate — Austin’s under six. That arithmetic alone eliminates a substantial portion of even high-earning households from the San Francisco market at the price-to-income ratio that market demands.

The national median home price stood at $404,300 in Q1 2026 per NAR, meaning Austin sits just barely above the national baseline while San Francisco clocks in at 3.34 times the national median. That ratio is not a function of local income levels justifying it — it is a function of constrained supply, regulatory density limits, and decades of underbuilding relative to demand. Buyers entering today do not inherit those supply constraints; they pay for them.

Property Taxes: California’s Hidden Advantage and Texas’s Surprise

The conventional wisdom — “Texas has no income tax, so property taxes must be manageable” — breaks down badly in Austin. Travis County’s combined effective property tax rate for homeowners, including city, county, and school district levies, sits at approximately 1.9%, according to aggregated local taxing authority data and analysis by the Lincoln Institute of Land Policy’s 50-State Property Tax Comparison Study (2024 tax year, released July 2025). On a $415,300 home, that produces an annual tax bill of roughly $7,890, or $658 per month.

San Francisco, counterintuitively, offers one of the lowest effective property tax rates for new buyers of any major American city — but only relative to its astronomical price base. California’s Proposition 13 limits the base property tax rate to 1% of assessed value at purchase, and San Francisco adds voter-approved bond measures and special assessments that bring the combined FY 2024–2025 rate to approximately 1.17%, per the SF Assessor-Recorder’s published rate schedule. On a $1,350,000 purchase that means $15,795 annually, or $1,316 per month — nearly double Austin’s dollar amount, despite a lower percentage rate. The property tax variation across metro areas is one of the most overlooked factors in city-to-city comparisons.

One nuance matters here: Prop 13 locks in that assessment at purchase and limits annual increases to 2% or the rate of inflation, whichever is lower. Austin’s homestead exemption caps annual appraisal increases at 10% for primary residences. Both protections benefit long-term owners — but they do nothing for buyers entering either market today at current prices.

Homeowner Insurance: Texas Pays More, California Faces Availability Risk

Texas homeowners paid an average annual premium of $3,291 in 2024, according to the Texas Department of Insurance’s official market overview — the highest major-market average in the country outside of Florida. Hail, wind, and severe convective storms drove a 23.3% rate increase in 2023 alone, per S&P Global Market Intelligence data. Austin sits in the heart of this risk zone. At $274 per month, insurance is the third-largest line item in an Austin homeowner’s monthly cost stack.

San Francisco’s insurance picture is cheaper in dollar terms but increasingly fraught in availability terms. NerdWallet’s 2026 analysis puts the San Francisco city-level average at $1,715 per year for standard coverage limits. For a home worth $1,350,000, replacement cost coverage — the only coverage that actually makes a buyer whole after a total loss — will require substantially higher dwelling limits, pushing the realistic annual premium for a median-priced San Francisco home to a range of $3,000–$5,000 annually based on coverage-level scaling from multiple quote sources. This analysis uses a $3,600 annual figure ($300/month) as a conservative midpoint, noting that the California Department of Insurance’s mandatory FAIR Plan remains a last-resort option after insurers have continued pulling back from the state following the 2025 wildfire season. The Sun Belt cost benchmarks for insurance contrast sharply with California’s growing availability constraints.

Full Cost of Ownership: The Five-Component Stack

PITI — principal, interest, taxes, and insurance — captures the contractual carrying cost of a home. Adding 1% of purchase price annually for maintenance converts PITI into total cost of ownership, the figure that actually determines what a household spends to keep its asset in place. The table below shows each component side by side.

San Francisco’s total monthly ownership cost runs $6,204 more than Austin’s — a gap of $74,448 per year. That figure exceeds the entire annual property tax bill on a median Austin home. Put differently, the annual carrying cost premium of owning a median San Francisco home versus a median Austin home is itself larger than the total annual cost of owning in many affordable luxury markets for $150k earners.

Maintenance costs often get underweighted in these comparisons. San Francisco’s pre-war housing stock — more than half the city’s homes predate World War II — carries above-average maintenance demands. The 1% heuristic, while standard, almost certainly understates true long-run maintenance costs for older SF properties. Austin’s newer suburban stock generally tracks closer to the 1% figure, though HVAC systems working against Texas summers and ongoing landscaping costs add real complexity.

Finluxy Housing Affordability Index

The Finluxy Housing Affordability Index expresses total monthly cost of ownership (PITI + maintenance) as a percentage of gross monthly income for the target household. The mortgage industry’s front-end debt-to-income ratio (DTI) threshold — the standard lender ceiling for housing expenses alone — sits at 28%. Markets above 40% are effectively unaffordable for the modeled income level; markets above 60% require income multiples that most $150k households cannot sustain.

San Francisco scores 76.7% at the $150k income level — more than 2.7 times the mortgage industry’s front-end DTI threshold. Even at $200,000 annual income, the index sits at 57.5%, still nearly double the 28% guideline and comfortably above the “effectively unaffordable” 40% mark. Austin’s 27.1% is the only figure in this comparison that falls inside the 28% threshold, and just barely. For a $150k household, Austin’s median home is the only market here where the math actually works by conventional lending standards. The full monthly cost of owning across major US cities shows how these two markets bracket most of the country’s range.

Price-to-Income Ratio: The Structural Gap

The price-to-income ratio (PIR) — median home price divided by metro median household income — provides a market-wide measure of structural affordability that cuts through individual income scenarios. Census Bureau ACS 2024 1-year estimates put the San Francisco–Oakland–Fremont metro median household income at $135,590 and the Austin–Round Rock–San Marcos metro at $99,897.

San Francisco’s PIR of 9.96 means the typical household in that metro would need nearly a decade of total gross income — saving every dollar — to purchase the median home. Austin’s 4.16 PIR is elevated by historical standards (the traditional rule of thumb hovers around 3×) but sits in a range where homeownership remains achievable with disciplined saving. The US city real estate cost comparison guide shows how these PIRs rank nationally — San Francisco is consistently in the top three most expensive markets by this measure, alongside New York City and Miami.

What makes San Francisco’s PIR especially punishing is that the metro’s high incomes have not kept pace with prices. A PIR of nearly 10 in a market with a $135,590 median income implies a price structure that has decoupled from local earnings and now reflects global capital flows, tech wealth concentration, and institutional demand as much as ordinary household purchasing power.

What the Data Shows That Most Coverage Overlooks

Nearly every San Francisco vs. Austin comparison focuses on sticker price and mortgage payment. The overlooked factor is the compounding nature of maintenance costs at high price points. In San Francisco, 1% annual maintenance on a $1,350,000 home amounts to $13,500 per year — $1,125 per month — before any emergency repair, before any capital improvement, and before any discretionary upgrade. That single line item exceeds the total monthly housing cost in many markets where $350,000 is still a viable price point. A San Francisco homeowner running 1% maintenance is spending more per month on upkeep alone than an Austin homeowner spends on their entire PITI. This dynamic does not show up in published affordability indices that measure only mortgage payments — and it materially changes the lifetime cost-of-ownership calculation.

There is a related distortion on the Austin side. Austin’s headline affordability advantage is real but narrowing, and its insurance costs represent a structural vulnerability that price-only analyses miss. Texas ranked as the state with the largest homeowner insurance rate increase in 2023 — 23.3%, per S&P Global — and the Texas Department of Insurance’s official 2024 average of $3,291 for a homeowners policy already reflects a market under sustained pressure. With catastrophic hail seasons and increasing severe weather frequency in Central Texas, Austin’s carrying cost floor has significant upward pressure that SF’s more stable (if expensive) insurance market does not face to the same degree. For buyers comparing weather-exposed Sun Belt markets, insurance trajectory is as important as today’s premium.

What This Means for $150k+ Households

For a household earning exactly $150,000, San Francisco’s median home is not a stretch — it is categorically unaffordable by any standard metric. At 76.7% on the Finluxy Housing Affordability Index, the total ownership cost would consume more than three-quarters of gross income before taxes, retirement contributions, or any other expense. Even at $200,000 annual income, the index reads 57.5% — a figure that would require aggressive income growth assumptions, a paid-off second income stream, or a significantly below-median purchase price to make sustainable. Households at this income level who want to own in San Francisco are effectively shopping for condos, outer-neighborhood properties well below the metro median, or accepting co-ownership arrangements. The Los Angeles price-to-income reality follows a similar pattern at a slightly lower price tier.

Austin is the functionally different scenario. At 27.1% on the Finluxy Housing Affordability Index, a $150k household buying the median Austin home sits just inside the conventional 28% front-end DTI ceiling — before taxes or retirement are touched. That leaves real room for savings, discretionary spending, and the income volatility that tech and professional households typically experience. The trade-off is a market in structural decline: Austin ranked third in the US for year-over-year median home value declines in 2025, per Realtor.com’s annual market analysis, and months of inventory stood at 5.5 as of Q1 2026 per Unlock MLS. Buying a depreciating asset at 4.16× income is not painless — but it is a categorically different risk profile than buying a stagnating asset at nearly 10× income. For households considering similar trade-offs in other Sun Belt markets, the Nashville real estate cost benchmarks and East Coast comparison markets offer useful parallels.

The core decision for a $150k+ household is not really San Francisco vs. Austin — it is whether a California premium of $74,448 per year in additional carrying costs produces $74,448 per year in economic, career, or lifestyle return. That answer is individual. The data simply clarifies what the premium is, precisely, so the decision gets made with accurate numbers rather than marketing narratives about either city’s relative value.
