Quick Answer

The bill's core real-estate impact is tax incentives: continuation or expansion of accelerated depreciation, changes to the SALT deduction cap, and the tax treatment of investment property — directly reshaping the math for high earners and investors.

Key Takeaways

  1. 1The bill's depreciation provisions affect early-year tax benefits for investment property
  2. 2SALT cap changes affect the real tax burden of owners in high-tax states
  3. 3Investment-incentive changes reshape the return math for investment property
  4. 4Bigger impact on high earners and investors than ordinary owner-occupants
  5. 5Recalculate with your CPA based on your own tax situation

The One Big Beautiful Bill (The Great American Comeback Act) is the most significant legislation of Trump's second term, passing the House with a slim majority on May 22, 2025. For the real estate market, the policies that truly determine direction are not granular tax-deduction provisions but four macro-level policy thrusts: tech hiring, debt and inflation, AI investment, and remittance controls. The net effect broadly benefits the U.S. housing market — particularly the West Coast, anchored by tech industry concentration.

Tech Hiring Revival: Restoring Immediate R&D Expensing

The current unemployment rate for computer science graduates stands at 6.1% — last among all majors — driven not only by AI displacement but also by Section 174 of the tax code enacted in 2022. The 2017 Tax Cuts and Jobs Act required R&D expenditures starting in 2022 to be amortized over 5 years, inflating book profits and squeezing cash flow. Microsoft as a result paid $4.8 billion in additional taxes and laid off 16,000 employees; Meta laid off 21,000.

The One Big Beautiful Bill restores immediate expensing for R&D and software development from 2025 through 2029 — effectively returning the cash-flow benefit to tech companies and incentivizing rehiring. Tech salaries are the highest of any sector; new positions translate directly into qualified homebuying demand, providing an immediate boost to West Coast housing. This is the most certain and direct positive effect of the bill on housing — it directly repairs a tax-policy pathogen that has suppressed tech hiring for several years.

Debt Expansion: The Inflation and Rate Risk

As of June 2025, total U.S. national debt stands at $36.2 trillion, with the federal deficit cumulating at $1.1 trillion and spending growth (7%) outpacing revenue growth (5%). Multiple analyses estimate the bill adds at least $2.5 trillion to deficits over 10 years — 25 times the ~$100 billion cut by Musk's DOGE initiative.

Large-scale deficit spending raises total social demand and could reignite inflation, potentially forcing the Fed to hold rates high, pushing up mortgage rates and reducing affordability. This is the bill's primary potential negative for housing — but its realization depends on the actual trajectory of inflation and employment. In short, the bill is 'short-term positive, medium-term uncertain' for housing: the near term is lifted by tech hiring and AI investment; the medium term requires vigilance about debt-driven inflation pushing mortgage rates higher.

AI Investment: Fueling Tech Companies

The bill increases AI investment in four directions: using AI to modernize government, applying AI to Medicare anti-fraud, centralizing AI policy authority from states to the federal government, and incentivizing federal and private-sector AI talent recruitment. Federal centralization of AI policy is especially significant.

Tech companies no longer need to build 50 different versions for 50 different states — they can offer comprehensive solutions to one large federal customer, reducing R&D costs and expanding margins. These investments will push up tech stock prices, growing the wealth of Seattle and Bay Area tech elites and New York's financial capital, providing strong support for those cities' home prices. Given Seattle home prices' strong positive correlation with the NASDAQ (lagging by ~6–8 months), AI investments driving up tech stocks will eventually translate into greater high-end purchasing power in Seattle.

Remittance Controls: An Unexpected Liquidity Variable

The bill requires non-U.S. citizens sending money abroad to pay a 3.5% excise tax, directly affecting ~50 million people, including ~23 million green card holders, ~14 million students and work visa holders, and ~12 million undocumented immigrants. U.S. outward remittances were $656 billion in 2023 — if a portion stays in the country due to this surcharge, relative to M1 of $18.67 trillion in April 2025, it's roughly equivalent to a 3.5% liquidity injection.

Remittance ControlValue
Excise tax rate3.5%
Affected population~50 million
Annual remittances$656B
Post-2020 stimulus price surge+32% nationally

The effect is analogous to the 2020 CARES Act — that fiscal stimulus drove national home prices up 32%, with Seattle, Bay Area, and other supply-demand-constrained markets seeing prices double. This 'retained in-country capital' effect partially flows into equities and real estate, providing additional demand support.

Timeline of Effects

TimeframeDominant ForceEffect on Housing
2025–2027R&D expensing + AI investment + retained remittancesDefinite positive
2027–2030$2.5T deficit-driven inflationPotential headwind
StackedStablecoin ActPotentially 10%+ additional upside

In the near term (2025–2027), restored immediate R&D expensing and AI investment are the most certain positive forces — directly stimulating tech hiring, pushing up stock prices, and enhancing high-end purchasing power, benefiting West Coast housing. In the medium term (2027–2030), $2.5 trillion in deficit-driven inflation and rate risk may gradually emerge as a housing headwind. Notably, the Stablecoin Act — being developed in tandem — is estimated to potentially add more than 10% to U.S. home prices, further reinforcing medium-to-long-term support for tech-concentrated market housing.

Special Note for Washington State Buyers

R&D expensingBenefits tech employmentSame benefit (tech-concentrated)
AI investmentBoosts tech stocksDirect benefit to Seattle

Washington State has no personal state income tax, so SALT deduction cap adjustments have limited impact on local homeowners. But R&D expensing and AI investment are genuine direct benefits for tech-concentrated Seattle. For Seattle buyers: capture the 2025–2027 tech hiring recovery window, while building contingency plans for post-2027 inflation risk. Specific tax impacts must be recalculated with your CPA based on your own income structure and ownership structure — there is no one-size-fits-all answer.

Summary

Across the four policy dimensions, the bill's net effect benefits U.S. real estate — particularly tech-concentrated West Coast markets. Restoring immediate R&D expensing and AI investment are the most certain near-term positive forces; debt-driven inflation risk is the medium-term variable to watch.

For Seattle's Chinese-American buyers and investors: capture the 2025–2027 window of tech hiring recovery and capital inflows, while building contingency plans for potential post-2027 inflation and rate risk. Specific tax impacts must be recalculated with your CPA based on your individual income structure and ownership approach.
