Tax land, not improvements — phased in over 8–10 years
The single largest distortion in US housing today is a demand-side subsidy regime — the Mortgage Interest Deduction and Section 121 capital-gains exclusion — capitalizing into land prices on a structurally fixed supply. The Accord weans the country off those subsidies and shifts the federal tax burden onto the unimproved value of land itself. The mechanism is a phased-in Land-Value Surcharge (LVS) that starts at 0.1% in Year 1, rises 0.05% per year, and reaches a terminal 0.5% by Year 9. Structured as an income-tax adjustment under the 16th Amendment (the “LAND Act” legal model), the LVS avoids the apportionment-clause friction a direct land tax would face and rides on settled federal income-tax authority.
The MID and Section 121 exclusion phase out on the same glide path, replaced by a flat First-Time Stability Credit available only to middle- and low-income first-time buyers — restoring the original homeownership-promotion intent without the runaway capitalization. Federal grants (transportation, infrastructure, housing) become conditional on locality-level supply reforms: parking-decoupling, vacancy multipliers on idle lots near transit, by-right approvals for compliant infill, and elimination of single-family-only zoning in transit-served areas. When regional housing prices exceed a Housing- Finance-Board-defined surge threshold, the Speculation Brake fires automatically: a 0.25% transaction tax on non-primary residences and an LTV cap reduction to 60% on the same.
Bring underutilized parcels into productive supply
Developable urban land held vacant past a threshold pays an annual surcharge calibrated to the local housing-shortage signal. Triggers via the COMPASS housing-domain indicator at the tract level — the surcharge activates only where the shortage is documented, not as a blanket land tax.
- Parcel in active permitted development
- Owner-occupied homestead
- Documented infrastructure constraint (utility capacity, soil remediation)
- Designated open-space conservation
Federal buildings that have been underutilized for 5+ years in tracts with documented housing shortage enter a streamlined repurposing review. Historic-designation, environmental, and accessibility requirements remain on the table — but they're evaluated against the public benefit of resolving the local housing shortage rather than treated as absolute blockers.
