Brownsville’s SpaceX boom arrives as a property tax bill

Bob Torres has sold houses around Brownsville, Texas, for 42 years. He says his own home was worth about $200,000 in 2022. Now he puts it at around $700,000, and some of his clients are asking him to sell theirs because they can no longer afford the property tax.

SpaceX’s listing on 12 June turned an estimated 4,000 or more current and former employees into millionaires, at least on paper. About 4,300 SpaceX staff work in Cameron County, the southernmost corner of Texas, where the company builds and launches Starship from its Starbase site on the Gulf coast.

Welders, machinists and cafeteria workers held equity alongside engineers, because SpaceX distributed shares widely. Brownsville, a border city of modest incomes, now has a population of newly liquid neighbours.

A property market that was already moving

The effect on house prices began well before the listing. According to the Texas Real Estate Research Center at Texas A&M University, the median appraised value of a property in Cameron County rose from $75,800 in 2019 to $171,900 in 2025, an increase of 127 per cent.

The Texas median rose 65 per cent over the same period. Median homeowner tax bills in the county rose 57 per cent, from $1,740 to $2,740, against 42 per cent statewide.

The research centre’s affordability index shows how far this has gone. In the second quarter of 2026, median family income in the Brownsville–Harlingen metro area was only 1 per cent higher than the income needed to buy a median-priced home.

In the 2010s it was sometimes more than 50 per cent higher. By that measure, the median family that lives there can now only just afford the median home.

The tax bill arrives before the windfall

Property taxes in Texas are levied on appraised value. A rise in the market therefore reaches every homeowner, including those who have no intention of selling and no SpaceX shares. “This is the whole big dilemma,” Torres told the Texas Tribune. “Who is SpaceX benefiting dollar-wise?”

The city proposes to keep its tax rate at 60 cents per $100 of valuation, which on rising appraisals is expected to raise about $3mn in extra revenue, and to add about 10 per cent to a typical homeowner’s bill. City manager Alan Guard said that residents are “not asking for less service, they want more”.

Lynn Krebs, an economist at the Texas A&M research centre, said “local governments can actually completely offset the increase in property values” by cutting rates. Brownsville’s proposal does not do that.

Unlike Silicon Valley, there is land

Brownsville’s one structural advantage is space. Researchers at the centre note that it does not face the supply constraints that made Silicon Valley’s housing crisis so intractable. Master-planned communities are spreading; at Madeira, a 1,300-acre development, homes start in the mid-$300,000s.

More employers are coming: the drone-vessel maker Saronic has announced a $3.2bn shipyard at the Port of Brownsville that it says will employ 10,000 people over ten years.

If builders keep up, the new money and new jobs could leave Brownsville richer without pricing out the people already there. It has not often worked out that way in boom towns. In the meantime there is an awkward asymmetry: SpaceX employees can choose when to sell their shares, while their neighbours find out what the boom means for them when the appraisal notice arrives.
