Onyx Reserve on Why South Florida Keeps Attracting Family Offices and High-Net-Worth Investors

Florida recorded a $20.65bn net inflow of adjusted gross income from domestic migration in tax year 2023, the largest of any state, per MIAMI REALTORS’ analysis of IRS data, with Palm Beach County first among all counties at $3.04bn. The money kept arriving while the sector meant to employ it shrank.

Tommy Shields, Head of Investor Relations at Onyx Reserve, argues that the migration gets misread whenever it is treated purely as a balance-sheet event.

“What moved here was households, not spreadsheets,” Shields said. “A family relocating is choosing schools and a doctor and a place to be on a Tuesday night. The investment consequences show up two or three years later, and they show up because those people now have neighbours.”

The tax data is the least arguable part of the story

Most claims about South Florida’s rise rest on anecdote. The migration figures do not, because they come from tax returns.

MIAMI REALTORS’ analysis of IRS Statistics of Income data for tax year 2023 found Florida with a $20.65bn net inflow of adjusted gross income from domestic migration, and a cumulative $137.0bn across 2019 to 2023. Palm Beach County led every county in the nation at $3.04bn for the year and $22.7bn cumulatively.

The composition matters more than the total. People moving into Palm Beach County in 2023 had an average income of $178,085, against $98,527 for those moving out, according to the same analysis. Out-of-state movers into Florida reported an average income of $122,530 in 2023, the highest figure of any state. Florida also counted 77,760 millionaire tax filers in tax year 2022, second-most in the country.

A state can gain population and lose income. Florida gained both, and the income gained per household was substantially higher than the income lost.

The millionaire count is now large enough to be an industry

Henley & Partners, in its World’s Wealthiest Cities Report published on 8 April 2025, ranked Miami 32nd globally with 38,800 resident millionaires as at the end of 2024. A city ranked in that band is no longer an outpost of somebody else’s wealth centre.

At the top of the distribution the concentration is sharper still. CoStar, citing Henley data in January 2026, reported that West Palm Beach now has 78 residents holding $100m or more in liquid assets, a population small enough to fit in a single restaurant and large enough to support an entire private banking ecosystem.

Which is roughly what has happened.

The institutions followed, and they moved functions rather than staff

The clearest institutional signal came on 20 January 2026, when Wells Fargo confirmed it would move the headquarters of its wealth and investment management division to One Flagler in West Palm Beach, taking 50,000 square feet and relocating about 100 employees including senior executives by the end of 2026, as reported by CoStar News. It is the first major US bank to move a wealth headquarters to Florida.

Around it, downtown West Palm Beach has assembled a tenant roster that includes Morgan Stanley, Goldman Sachs, Elliott Management, Point72, JPMorgan and BlackRock, per the same CoStar reporting. The Business Development Board of Palm Beach County reports that more than 140 companies relocated or expanded in the county over the past five years, representing more than 13,110 direct jobs and $1.12bn in capital investment, and that roughly ten companies moved their headquarters into the county in the first two months of 2026 alone.

The office market reflects the density. Brickell office vacancy stood at 6.8% in June 2026 against a 17.7% US national average, and West Palm Beach and Boca Raton office rents grew 21.2% year on year to $49.9 per square foot, according to MIAMI REALTORS citing Yardi Matrix.

The counterweight: the finance payroll is shrinking

Here is the figure that complicates everything above.

Financial activities employment in the Miami-Fort Lauderdale-West Palm Beach metro stood at 215,600 in July 2026 against 221,000 in July 2025, a fall of 5,400 jobs or 2.4% year on year, according to the US Bureau of Labor Statistics State and Metro Area Employment series, last updated on 21 August 2026. The June-to-June comparison runs the same way, 215,400 against a revised 221,100, down 5,700 jobs or 2.6%.

A region that has spent four years announcing financial relocations now employs several thousand fewer people in finance than it did a year ago.

Both things are true at once, and the gap between them is the most interesting feature of the dataset. The money kept arriving while the sector that handles it got smaller. Family offices are small employers by design, which is close to the point of them, and the Wells Fargo relocation, the single largest wealth-management move the region has recorded, involves about 100 employees against a metro payroll that lost fifty-four times that number in a year.

Nothing in the contraction argues that the migration was imagined. The IRS figures are tax returns and the office leases are signed. What the contraction says is that the two series move independently, because a principal who relocates to Palm Beach carries capital rather than a department. The people who administer that capital can stay in New York, or be cut there, and the Florida payroll never registers them either way.

That has consequences for anyone underwriting local commercial property on an employment forecast, because the employment line is now pointing down while the rent line points up. Office demand from a family office is a floor of a floor. Demand from a bank operations centre is three hundred desks. The region has been getting more of the former than the latter, and the rent figures show it: scarcity of good space is doing more work than headcount growth, and it is doing that work in a year when the sector shed jobs.

Anyone forecasting from press releases will overshoot. Anyone forecasting from the BLS series alone will miss the capital entirely.

What the family office data actually supports

Deloitte Private’s Family Office Insights Series found the number of single family offices worldwide rose from 6,130 in 2019 to 8,030 in 2024, a 31% increase, with a projection of 10,720 by 2030. North America accounted for 3,180 of the 2024 total, the largest regional share. Deloitte put family office assets under management globally at $3.1trn in 2024, projected to reach $5.4trn by 2030.

No credible primary source publishes a Florida-specific family office count, and the figures that circulate come from commercial directories with unpublished methodology. What can be said is that North America holds the largest concentration of these offices globally and that their capital stays close to home. The UBS Global Family Office Report 2025 found US family offices allocate 86% of portfolios to North America, the strongest home bias of any region surveyed.

Domestic capital with a strong domestic preference, held by principals who have physically moved to Florida, tends to find its way into assets those principals can drive past.

Shields, who handles investor relations at Onyx Reserve, puts the same point the other way round. The households arrived first, and the allocations followed them.

The three counties are not one market

Reporting tends to flatten South Florida into a single unit. The July 2026 county data from MIAMI REALTORS shows how different the three actually are.

Metric, July 2026 Miami-Dade Broward Palm Beach County
Sales of $1m or more 394, up 15.5% YoY 300, up 33.93% YoY 445, up 36.5% from 326
Single-family median $685,000, up 3.79% not reported here $660,090, up 7.64%
Condo median $400,000, down 1.48% $255,000, down 3.77% not reported here
All-cash share of sales 35.1% 34.5% 47.7%

Palm Beach County leads on luxury growth and on cash. Its 47.7% cash share in July 2026 is more than twelve points above either neighbour, which is a reasonable proxy for how much of its buying is being done by people who do not need a mortgage approval. Miami-Dade’s condo median fell while its single-family median rose, a split that has held for several quarters.

International money sits on top of all of it. MIAMI REALTORS reported that foreign buyers purchased $4.4bn of South Florida residential property in 2025, up from $3.1bn in 2024 across 5,300 transactions, accounting for 15% of dollar volume against a 2% US national average, with about 51% of those transactions all-cash.

What has not been settled

Two questions remain genuinely open.

The first is what the 2.4% payroll contraction is measuring. It could be South Florida catching a national wave of cost-cutting in financial services, in which case the jobs return when the wave passes. It could also be the settled shape of the thing, a region that houses principals and their capital without housing the staff who process it. Four years in, the second reading has the better of the evidence, and it would make South Florida a residence for capital rather than a workplace for it.

The second is durability. The IRS series runs through tax year 2023 and captures a period shaped by pandemic-era mobility and interest rates that no longer apply. Tax year 2024 and 2025 data will show whether Palm Beach County’s first-place ranking was a peak or a plateau, and nobody analysing the region today has seen it.
