See Tomorrow’s Property Tax Bill Before It Arrives
TaxDrift tracks overlapping municipal bond debt, local government budget deficits, and county CAD assessment lag across US jurisdictions to forecast millage rate hikes 12–36 months in advance.
Standard real estate listings and closing disclosures only present trailing 12-month property tax statements. They conceal newly issued school district capital bonds, growing municipal operating deficits, and 20%+ assessment lag spreads. When county tax assessors catch up or debt service payments commence, property taxes escalate sharply, compressing net yields and inflating monthly escrow obligations.

The TaxDrift Composite Formula & Data Layers
Debt Burden Velocity
Compiled from MSRB EMMA disclosures and Census Survey of Gov Finances. Evaluates total overlapping county, municipal, and special district (ISD, MUD, PID) bond debt per capita divided by median household income.
Assessment Lag Spread
Calculates the disparity between certified County Assessor (CAD) taxable valuations and FHFA House Price Index repeat-sales benchmarks. A widening gap signals an impending reassessment catch-up cycle.
Operating Deficit CAGR
Tracks 3-year compound annual growth rates of municipal operating expenditures relative to local tax revenue growth, highlighting structural deficits that will force statutory rollback rate increases.
