Cost of Living: San Francisco vs Denver (2026)
The canonical CA tech exit. SF's 13.3% top + 1.3% MHST surcharge vs CO's flat 4.4%. SF's median home tops $1.26M (Zillow ZHVI April 2026); Denver's $559K. SF rents push $3,800/mo for a 1BR; Denver $1,700. CO's TABOR amendment locks in the flat-rate structure constitutionally — and the 2026 ballot has a measure that would change it. SF anchors AI, biotech, and global venture capital. Denver concentrates aerospace (Lockheed, Sierra Space), outdoor recreation industry, and a growing tech corridor. Verdict at $200K renting: ~$32,000/yr in Denver's favor, dominated by housing — widens to $40K+/yr at $500K, $90K+/yr at $1M. The catch: Prop 13 protection means long-term SF owners face dramatically worse total cost in Denver if they sell.
Try the salary sliderThe tax math nobody else shows you.
Three taxes that shape the real comparison. Sources cited inline.
State income tax
Denver wins decisively on income tax — and the gap compounds at high incomes. CA effective ~6% at $100K, ~9% at $200K, ~11% at $500K, 13.3% at $1M+. CO flat 4.4% at every income level. At $100K: SF ~$5,800; Denver ~$3,750 → $2,050/yr Denver advantage. At $200K: SF ~$15,500; Denver ~$8,250 → $7,250/yr Denver advantage. At $500K: SF ~$45,000; Denver ~$21,250 → $23,750/yr Denver advantage. At $1M: SF ~$120,000+; Denver $43,250 → $76,750+/yr Denver advantage. Colorado's TABOR-protected flat 4.4% is the canonical destination for high-income CA exits that don't need the absolute zero of TX/FL/NV.

Property tax
Denver wins decisively on effective rate — but SF's Prop 13 protection inverts the math for long-term SF owners. SF's 1.18% is Prop 13-locked at purchase price + 2%/yr; long-term owners often pay 30-50% below market value. Denver's 0.48% applies to current market value via 6.8% assessment rate × ~79.2 mill levy. On equivalent $500K home (new buyer): SF ~$5,900/yr vs Denver ~$2,400/yr — $3,500/yr Denver advantage. For long-term SF owners with $400K+ Prop 13 basis on $1.5M+ market value home, the protection is often worth $15-25K/yr — losing it forever by selling can outweigh CO tax savings. Denver homeowners face TABOR-constrained but rising bills (assessment cycle every two years; 2026 saw bills jump 13-40% on flat values).

Sales tax
Sales tax favors SF marginally (8.625% vs 8.81% combined). On $50K of taxable spending: SF $4,313/yr vs Denver $4,405/yr — $92/yr Denver disadvantage. Both states exempt unprepared groceries. Denver's structure is unusual: 2.9% state (lowest in US) + 8.3% local (one of highest) = 8.81% combined. SF's structure: 7.25% state + 1.375% district = 8.625% (lowest of any major Bay Area city per Avalara April 2026).

Pair-specific tax considerations
These callouts apply specifically to the states in this comparison. They surface tax wrinkles, protections, and crises that change the calculus for your move.
California Prop 13: A Hidden Tax Cost of Leaving
If you bought a San Francisco home before 2010, Prop 13 (1978) has capped your annual property tax assessment increases at 2%. Your effective property tax may be 50-80% below current market rates — saving $15,000-$30,000+/yr on a $1.5M+ home now valued well above its protected basis.
Selling means losing this protection forever. Prop 19 (2020) further restricted parent-to-child basis transfers — children inheriting a Prop 13 home must move in within 1 year as primary residence to retain the basis (with a $1M exemption above current taxable value); rental and investment properties get fully reassessed at market on inheritance. For long-term California owners, the implicit Prop 13 subsidy can exceed the entire income tax savings of moving to Colorado over 5-10 years. New buyers pay full market rate. Run the specific math on your protected basis vs reassessment cost before assuming a move saves money.
Colorado TABOR + Proposition 121: Constitutionally Capped Tax Rates
Colorado's Taxpayer's Bill of Rights (TABOR, 1992) is a constitutional amendment limiting state revenue growth to inflation + population growth. Excess revenue must be refunded to taxpayers. This mechanism has driven Colorado's flat income tax rate from 4.63% down to 4.4% (Proposition 121, 2022). The flat-rate structure itself is constitutionally protected — graduated brackets require a constitutional amendment.
Pending: Protect Colorado's Future ballot measure for November 2026. Would replace the 4.4% flat with graduated brackets: 4.2% to $100K, 4.4% to $500K, higher above. The campaign claims it would raise $2.3B/yr while cutting taxes for 98% of Coloradans. If passed, it would repeal a portion of TABOR's flat-tax requirement. Voters have historically rejected most tax-increase measures. TABOR refunds for 2025 are expected to be $20-62 (single) or $40-124 (joint) — dramatically smaller than 2022-2024's $750-800 refunds — and are projected to disappear entirely for tax year 2026 due to revenue falling below the cap.
The full breakdown — including taxes.
The current San Francisco-vs-Denver comparisons online skip taxes entirely. They're the biggest variable. Here's everything.
| Category | San Francisco | Denver | Difference | Why |
|---|---|---|---|---|
| Housing (1BR rent, typical) | $3,790/mo | $1,700/mo | -55% | Denver ~55% cheaper. SF 1BR median $3,790 (Zumper, April 2026, +20% YoY). Denver 1BR ~$1,700 (Zumper / RentHop / RentCafe convergent April 2026). |
| State income tax (on $100K) | $5,800/yr | $3,750/yr | -$2,050 | CA ~5.8% effective at $100K (graduated 1-9.3%); CO flat 4.4% on federal taxable income |
| Property tax (on $500K home, new buyer) | $5,900/yr | $2,400/yr | -$3,500 | SF 1.18% × $500K vs Denver 0.48% × $500K — long-term SF owners pay much less under Prop 13 |
| Sales tax (on $50K taxable spending) | $4,313/yr | $4,405/yr | +$92 | SF 8.625% vs Denver 8.81% combined; both exempt unprepared groceries |
| Groceries (weekly) | $175/wk | $130/wk | -26% | Denver ~26% cheaper per BLS Consumer Expenditure Survey + ACER COLI |
| Transportation (yearly) | $4,800/yr | $6,200/yr | +$1,400 | SF lower due to BART/Muni transit + walkable density (~21% transit commute share); Denver more car-dependent (RTD light rail covers limited area, 56% drive-alone) |

By the numbers.
Quotable stats that make the comparison concrete.
Why this comparison matters in 2026.
The macro picture before the math.
The San Francisco to Denver migration is one of the most data-tested CA exit moves of the past five years. Both cities are anchored by knowledge-economy clusters with overlapping talent pools — but the cost-of-living gap is among the largest of any major US city pair. SF's median home price is 2.25× Denver's. SF's 1BR rent is 2.2× Denver's. SF's effective state income tax at $200K is roughly 1.9× Denver's. The interaction creates one of the most decisive verdicts in any cross-state cost-of-living comparison.
The income tax case heavily favors Denver. California's progressive structure (1%-12.3% with 1% Mental Health Services Tax surcharge above $1M, formally the Behavioral Health Services Act since 2024) creates dramatic burdens at high incomes. Colorado's flat 4.4% — constitutionally protected via TABOR (1992) and recently lowered from 4.55% via voter-approved Proposition 121 (2022) — is among the best US tax math for high earners outside no-income-tax states. At $200,000 wages: SF pays ~$15,500 in CA state income tax; Denver pays ~$8,250 — $7,250/yr Denver advantage. At $500,000: $45,000 vs $21,250 — $23,750/yr Denver advantage. At $1,000,000: $120,000+ vs $43,250 — $76,750+/yr Denver advantage. Colorado's flat structure compounds aggressively in favor of high earners. Note: a 2026 ballot measure (Protect Colorado's Future) would replace flat 4.4% with graduated brackets — outcome uncertain.
Housing dominates the verdict. SF's Zillow ZHVI is $1,258,198 (April 2026, +3.1% YoY despite tech layoffs and AI bubble concerns); Denver's ZHVI is $558,705 (-3.6% YoY, market in transition from seller to buyer's market). On equivalent purchases at 20% down with 6.23% mortgage: SF PITI runs ~$8,200/mo all-in; Denver ~$3,800/mo — a $4,400/mo gap, $52,800/yr, exceeding $1.5M over a 30-year mortgage even before factoring lower Denver insurance. For renters, SF 1BR median is $3,790 (Zumper April 2026); Denver $1,700 — $25K/yr gap. The rental gap alone exceeds tax savings at most income levels.
But Prop 13 protection inverts the picture for long-term SF owners. If you bought a SF home before 2015 (and especially before 2010), Prop 13 has capped your assessment increases at 2%/yr for decades. Your effective property tax may be 30-50% below current market — saving $15-30K+/yr versus a new buyer. Selling means losing this forever AND moving into Colorado's full-market-value reassessment regime. Long-term SF owners often face dramatically worse total cost in Denver despite the tax + housing savings on paper. The math depends critically on your basis vs current market. Prop 19 (2020) further restricted parent-to-child basis transfers, making this protection harder to pass to heirs.
The career ecosystems differ but increasingly overlap. SF anchors AI (OpenAI, Anthropic, xAI, Mistral, Cohere; thousands of stealth startups), biotech (UCSF cluster, Genentech, Recursion, Vir), and global venture capital (Sequoia, a16z, Founders Fund, Khosla). Denver concentrates aerospace (Lockheed Martin, Sierra Space, Raytheon, ULA), outdoor recreation industry (VF Corp, Patagonia, Black Diamond), renewable energy (NREL, Solaria, Vestas), and a growing tech corridor (Palantir HQ in Denver since 2020, Google Boulder, Twilio). For pure tech roles, SF retains structural advantages in early-stage / AI / biotech. For aerospace, outdoor industry, or established-tech leadership, Denver is competitive or better.
The 2026 verdict at $200,000 wages renting shows ~$32,000/yr in Denver's favor — among the largest gaps in any US city pair. At $500K it grows to $40K+/yr. At $1M it exceeds $90K/yr. Career sector and homeownership status typically dominate the decision: AI/biotech anchors keep professionals in SF; aerospace/outdoor industry/established-tech leadership pulls them to Denver; high-income renters favor Denver decisively at all income levels; long-term SF homeowners with significant Prop 13 basis face a closer call.
Five things that surprise people.
The framings most cost-of-living tools never mention. All sourced.
Colorado's flat 4.4% saves SF tech earners $76,750+/yr at $1M income.
Colorado constitutionally requires a flat income tax — graduated brackets need a constitutional amendment. At 4.4% flat (lowered from 4.63% via voter-approved Proposition 121, 2022), Colorado's high earners pay among the lowest state income tax of any major-population state with an income tax. Compared to California's 13.3% top + 1% surcharge, the gap at $1M income exceeds $76,750/yr. For tech professionals at FAANG/big-tech compensation levels ($300K-$1M+), AI startup equity-comp recipients with major liquidity events, and venture capital partners, Colorado's flat structure provides better tax math than most state alternatives outside no-tax states. Note: a November 2026 ballot measure (Protect Colorado's Future) would replace the flat 4.4% with graduated brackets up to ~5.7%+ on high earners — uncertain outcome could change the calculus.
[Source: California FTB; Colorado Department of Revenue; Tax Foundation 2026 →]SF home prices dropped through the AI bubble, but rents are spiking 20% YoY.
Counterintuitive 2026 SF dynamic: while Compass reported median sale prices hit a record $2.15M in March 2026 (+18% YoY) driven by AI startup wealth concentrating in mid-tier and mansion markets, broader Zillow ZHVI sits at $1,258,198 — only +3.1% YoY across the full city. Meanwhile rental market is spiking: Zumper reports SF all-bedroom median rent up 20% YoY April 2026, with 1BR median at $3,790 (highest of any US city). The structural drivers: AI startup hiring concentrating in SF specifically (not Bay Area broadly), return-to-office mandates from Anthropic/OpenAI/Google, and constrained 1BR/2BR supply. For renters, SF is harder to afford than at any point since 2019. For buyers, the AI-driven wealth surge concentrates in luxury bands and may not persist if AI valuations correct.
[Source: Compass / Bloomberg April 2026; Zumper April 2026 →]Denver's TABOR refunds collapse from $750+ to under $100 for 2025 — and disappear entirely for 2026.
Colorado's TABOR mechanism returned $8.5B+ to taxpayers from 2022-2024, with average refunds of $750-$800 per single filer. For tax year 2025 (filed spring 2026): single filers receive $20-$62, joint filers $40-$124. For tax year 2026: zero refunds expected — state revenue projected $308M below TABOR cap, the first time since the pandemic. The collapse reflects two forces: state expense growth from Medicaid and education obligations exceeding TABOR cap; and Democratic-led legislature redirecting surplus to targeted credits (child tax credit, EITC expansion). The temporary income tax rate reduction for TY 2025 is 4.36% (returning to 4.40% for TY 2026). Long-term implication: TABOR's per-taxpayer refund mechanism may be functionally dismantled even if the constitutional amendment remains.
[Source: Colorado Office of State Planning & Budget; CPR News February 2026 →]Denver-Aurora metro is the #2 destination for tech relocations from SF Bay Area.
Per LinkedIn migration data and U-Haul 2025 Growth Index, Denver consistently ranks #2 (behind Austin) for net inbound tech professionals from SF Bay Area. The structural drivers are concrete: 4.4% flat tax (vs 9-13.3% CA progressive), housing 56% cheaper at the city level (Zillow ZHVI $559K vs $1.26M), 300+ days of sun, mountain access for outdoor culture, and 1.5-hour flight back to SFO for client meetings. Major tech employers anchoring the corridor: Palantir HQ (Denver, 2020), Google (Boulder), Salesforce (Denver Tech Center), Uber (Denver office), Twilio (Denver). For founders specifically: Boulder has the highest startup density per capita of any US metro (Techstars-anchored). The trade-off most Bay Area exits cite as hardest: smaller VC ecosystem (Foundry Group, Access Venture Partners are Denver/Boulder anchors but ~10× smaller than SF's a16z/Sequoia/Founders Fund concentration).
[Source: LinkedIn Workforce Report 2025; U-Haul 2025 Growth Index →]California's MHST surcharge applies to SF residents earning $1M+ — and to remote workers with CA-source income.
California's 1% Mental Health Services Tax (formally Behavioral Health Services Act, BHSA, since 2024) applies to taxable income above $1,000,000, regardless of filing status. Critical detail: the surcharge applies to non-residents with CA-source income above $1M, including stock sales attributable to CA-based work and equity vests on RSUs granted while CA-resident. This is the FTB audit hot zone: tech employees who 'move' to Denver but retain CA-sourced equity income still face CA tax on the CA-attributable portion. Standard rule of thumb: 4-year RSU grants vested while CA resident remain taxable to CA on the proportion of vest period spent as CA resident, even after relocation. The 'safe harbor' provision (546+ consecutive days outside CA, less than 45 days/year in CA, less than $200K intangible income) provides limited relief. For high-earning SF tech workers planning a Denver move, run the FTB math on equity-comp vesting schedules before relocating — the 'savings' from moving may be smaller in year 1-3 than headline numbers suggest.
[Source: California FTB Publication 1031 (Resident Status); Mental Health Services Act / Proposition 63 →]Which city is right for you?
Six questions. Tax math + housing favor Denver decisively at every income level; lifestyle, career sector, and Prop 13 status flip specific cases.
Which one wins for who?
The right answer depends on career sector, income, homeownership status, and lifestyle priorities:
| Reader profile | Winner | Confidence | Why |
|---|---|---|---|
| Single, $80K, renting | Denver | Very High | $25K+/yr COL + tax + rent savings; SF unaffordable at this income |
| AI / ML researcher | San Francisco | Very High | OpenAI/Anthropic/xAI/Mistral concentration genuinely irreplaceable |
| Biotech R&D scientist | San Francisco | Very High | UCSF + Genentech + Bay Area biotech cluster unmatched |
| VC / Growth Equity partner | San Francisco | Very High | Sand Hill Road LP relationships + dealflow density |
| Aerospace engineer | Denver | Very High | Lockheed + Sierra Space + Raytheon + ULA concentration |
| Outdoor industry / brand professional | Denver | Very High | VF Corp / Patagonia / Black Diamond / REI HQ proximity |
| Tech professional, $200K, renting | Denver | Very High | $25K rent + $7K tax + $5K COL savings = ~$37K/yr advantage |
| Tech professional, $200K, buying | Denver | Very High | $700K cheaper home + lower property tax effective rate |
| $500K+ earner, renting | Denver | Very High | CO flat 4.4% saves $24K+/yr; rent saves $25K+/yr |
| $1M+ earner with significant equity comp | Denver | High | CO flat 4.4% saves $77K+/yr — but FTB audit risk on CA-source income |
| Long-term SF owner (Prop 13, $1M+ basis gap) | San Francisco | Very High | Prop 13 protection often worth $15-30K/yr; selling costs forever |
| Recent SF buyer (2020+), little equity | Denver | Moderate | Limited Prop 13 benefit; sale costs may not exceed CO savings |
| Family with school-age kids | Denver | High | Denver Public Schools + Cherry Creek strong; SF public school lottery problematic |
| Mediterranean climate priority | San Francisco | Very High | SF year-round mild, cool fog summers — not replicable in Denver (350K snowfall, 320 freezing nights) |
| Mountain access / outdoor priority | Denver | Very High | Front Range + Rocky Mountain access genuinely irreplaceable |
| Empty nester downsizing | Denver | High | Lower property tax effective rate + lower home price + outdoor lifestyle |
Confidence is editorial judgment, not a precise statistical estimate. "Very High" = the math is decisive; "Low" = the answer depends heavily on factors specific to your situation.
When the standard verdict flips.
Tax math + housing favor Denver decisively — but specific situations strongly favor San Francisco:
-
Career in AI / ML / Foundation ModelsOpenAI, Anthropic, xAI, Mistral, Cohere, Databricks, Glean, Perplexity, Together AI, Sakana — the AI cluster concentrates in SF specifically (not Bay Area broadly). Anthropic's HQ is SOMA. Most foundation-model companies are within 2 miles of each other. The talent network density is genuinely irreplaceable; Denver has Palantir + scattered AI groups but lacks the concentration.
-
Career in biotech / pharma R&DUCSF + Stanford + Genentech anchors create the densest biotech cluster outside Boston-Cambridge. Recursion, Vir, Insitro, Generate Biomedicines have major SF presence. Denver has no comparable biotech depth — UC Anschutz Medical Campus is a strong academic medical center but not industry-anchor scale.
-
Career in venture capital / growth equitySand Hill Road + SF financial district concentrate the largest US VC ecosystem by AUM (Sequoia, a16z, Founders Fund, Khosla, Greylock, Benchmark). LP relationships, dealflow networks, and emerging-fund infrastructure are difficult to replicate. Denver/Boulder has Foundry Group + Access Venture Partners + Techstars but ~10× smaller.
-
Long-term SF owner with significant Prop 13 protectionIf you bought before 2015 (especially before 2010), Prop 13 has capped your annual property tax assessment increases at 2%/yr — you may pay $15,000-$30,000+/yr below current market. Denver has no equivalent protection — full market value reassessment every 2 years. Selling means losing Prop 13 forever AND moving into CO's full-rate regime. Long-term SF owners often face dramatically worse total cost in Denver despite headline savings.
-
Mediterranean / temperate climate prioritySF's microclimate is genuinely unique: 50-65°F most of the year, no extreme heat, no snow, no humidity. Denver: 320+ freezing nights/yr, 60+ inches snow, summer afternoon thunderstorms, 95°F+ summer days, dry air requiring humidifiers. The climate shift is the most-cited difficulty for SF-to-Denver transplants — many leave within 3-5 years citing weather alone.
-
Single / dating / restaurant + culture prioritySF has 7,000+ restaurants in 49 sq miles, multiple Michelin-starred neighborhoods, world-class symphony/opera/SFMOMA. Dating pool 4× larger by raw numbers; LGBTQ+ scene unmatched outside NYC/LA. Denver is improving but operating at smaller scale — RiNo + LoDo + Highlands have strong restaurant scenes but lack the cultural depth and density.
-
High-income wage earner avoiding CA progressive taxColorado's flat 4.4% (TABOR-protected, recently lowered via Proposition 121) is significantly better than CA's 13.3% top + 1% MHST surcharge for high earners. At $500K: $24K/yr Denver advantage. At $1M: $77K+/yr Denver advantage. Combined with 50%+ lower COL, the financial case at high incomes is overwhelming. Note: 2026 ballot measure could change this — verify current rate before relocating.
-
Career in aerospace / defenseDenver-Aurora-Boulder concentrates Lockheed Martin Space (Littleton), Sierra Space (Louisville), Raytheon Intelligence & Space (Aurora), United Launch Alliance (Centennial), Northrop Grumman, plus NASA-affiliated NREL (Golden) and NCAR (Boulder). For aerospace careers specifically, Denver is structurally distinctive — ranks #2 US aerospace metro after LA. SF has minimal aerospace presence.
-
Career in outdoor recreation / outdoor industryDenver-Boulder is HQ corridor for VF Corp (North Face / Vans / Timberland), Patagonia (Denver office), Black Diamond, REI (Sumner WA HQ but major Denver presence), Salomon, Outdoor Research, plus dozens of cycling/skiing brands. Industry concentration at the executive and brand levels is meaningful. SF has Patagonia HQ in Ventura but limited outdoor-industry depth in the city itself.
-
Renter or first-time buyer prioritizing affordabilitySF 1BR rent $3,790 vs Denver $1,700 = $25K/yr difference. SF home median $1.26M vs Denver $559K = $700K+ difference. PITI on equivalent purchase: $4,400/mo gap = $52,800/yr. For middle-income earners, the financial case is overwhelming with minimal Prop 13 exposure.
-
Family with school-age kidsDenver Public Schools + neighboring Cherry Creek/Boulder Valley districts rank well. SF Unified School District uses a complex citywide lottery that drives many families to private school ($30-50K/yr/kid) or out of the city. For families, the school cost differential alone often justifies the move.
-
Mountain access / outdoor lifestyle priorityDenver: 75-90 min drive to Front Range skiing (Loveland, Echo Mountain). 90 min to Vail. Hundreds of miles of trails within metro. SF: 3.5-hour drive to Tahoe; ocean access but no mountain skiing. For people whose lifestyle centers on mountains, Denver is genuinely irreplaceable.
What you are accepting either way.
Both cities have real downsides — particularly given how different the climates and industry concentrations are:
- California tax burden among worst in US. Top 13.3% + 1% MHST surcharge above $1M. At $500K: $23K+/yr more than Denver. FTB audit aggression on out-of-state moves is high.
- Highest US housing costs. $1.26M median home, $3,790/mo 1BR rent. The cost-of-living math is brutal under $200K income, marginal at $300-500K, only manageable at $750K+.
- Earthquake risk. San Andreas + Hayward faults — major earthquake (M7+) statistically overdue. Earthquake insurance (CEA) costs ~$3-7K/yr extra on top of standard homeowners.
- Public transit increasingly unreliable. BART / Muni service quality declined post-pandemic. SF safety perception issues (open-air drug markets, retail theft) deter some residents and businesses.
- Tech-cycle concentration risk. Local economy heavily tied to AI bubble + tech equity comp. A correction would hit housing + jobs simultaneously.
- Cold winters with 300+ days requiring heating. 60+ inches snow/yr, lake-effect blizzards, ice storms. Heating costs add $100-$200/mo to utility bills vs SF's nearly zero heating need.
- Altitude adjustment. Denver sits at 5,280ft (Mile High City). New residents typically need 2-4 weeks for full acclimatization; some never fully adjust (chronic mountain sickness affects ~5%). Hydration requirements are 2-3× higher.
- Tornado / hailstorm risk on Front Range. Denver metro has the highest hail-damage costs of any US metro per State Farm. Annual hail-damage roof replacements common. Auto insurance ~30-40% above national average.
- Wildfire smoke from regional fires. Front Range air quality during August-September wildfire season can be hazardous; AQI exceeds 200 on some days. Climate trajectory worsens this annually.
- Property tax bills rising on flat home values. Denver homeowners saw 13-40% bill increases in 2026 even on flat market values, due to assessment-rate changes + expiring flat-dollar relief. The TABOR-constrained framework doesn't always protect bills.
- Smaller VC + foundation-model AI ecosystem. If your career anchors in early-stage tech investing or foundation-model AI research, Denver doesn't have the network density.
How sensitive is this answer? Highly — career sector, income level, and Prop 13 status flip the verdict.
- Change career sector from generic to AI / biotech / VC: SF wins decisively (industry concentration).
- Change career sector to aerospace / outdoor industry: Denver wins decisively.
- Change income from $200K to $1M: Denver tax advantage grows from $7K to $77K+/yr.
- Change renter to buyer of $1M home: Denver gap widens further (housing cost differential dominates).
- Account for Prop 13 protection (long-term SF owner): SF often wins on total cost despite headline taxes.

Author: Built by Abiot Y. Derbie, PhD — Postdoctoral Research Fellow. About the author.
Take-home pay calculations use 2026 federal tax brackets (single filer, standard deduction $16,100) plus the relevant state and local rates. They exclude pre-tax retirement contributions (401(k), HSA, FSA) and most local taxes that vary by employer.
Cost-of-living indexes use ACER (American Chamber of Commerce Researchers) and BLS regional CPI as primary sources, weighted across housing, groceries, utilities, transportation, healthcare, and miscellaneous categories.
Property tax figures are effective rates (median bill ÷ median home value) at the county level. They differ from nominal/posted millage rates because of homestead exemptions and assessment caps.
Mortgage projections assume 30-year fixed at the rate shown, conservative 2.5% annual appreciation, and standard PITI calculations. Past appreciation does not guarantee future returns.
