Home Prices Are Rising—So Why Can't Property Taxes Fall?

In economics, there is a combination almost everyone wishes for: their home keeps appreciating in value while the property taxes they pay keep declining. This demand sounds like a simple wish from an ordinary taxpayer, but in fiscal logic it is nearly self-contradictory. Around this topic, an article on the economics blog Conversable Economist sparked 586 comments and 259 upvotes on Hacker News, showing that it struck a chord with many people's real confusion.

A Seemingly Reasonable Yet Contradictory Demand

The title itself highlights the core tension: homeowners want their assets to appreciate, but they don't want to pay the tax burden that appreciation brings. Property taxes are typically levied as a percentage of assessed value. When home valuations rise, at an unchanged tax rate, the tax amount naturally rises too. To achieve both "home prices up" and "tax bill down," you must either lower the tax rate or change the entire assessment and collection mechanism.

The key issue is that one of local governments' main revenue sources is precisely property tax. Funding for schools, roads, fire services, public safety, and other public services often depends directly on this revenue. When homeowners collectively demand "valuations up, tax burden down," they are in effect asking the government to provide equal or even more services with less money, or to shift the burden onto other taxes and other groups.

The Fiscal Logic Behind Property Taxes

Property tax became the backbone of local finance because it is relatively stable, hard to evade, and directly tied to real estate—an immovable asset. Home appreciation usually means improved community environment, increased public investment, or strong market demand—and these factors themselves are partly supported by public services. In other words, there is a positive feedback loop between property appreciation and public services: good schools and good public safety drive up home prices, and the tax revenue from rising prices can in turn be reinvested into public services.

If this cycle is forcibly cut off—letting tax rates fall as valuations rise—homeowners may indeed see short-term relief, but in the long run it could lead to insufficient investment in public services, weakening the community's attractiveness and ultimately undermining home prices. This is precisely why many economists believe that "wanting both rising home prices and falling property taxes" is unsustainable.

Positive feedback loops are called "capitalization" effects in public economics. When the quality of community public services improves—for example, school rankings rise, crime rates fall, parks and transportation facilities improve—these benefits are partly converted into higher property values, because buyers are willing to pay a premium for better public services. Property tax happens to capture this value increment: rising valuations bring increased tax revenue, allowing local governments to continue investing in public services, forming a self-reinforcing cycle. Cases often cited in the literature include the significant impact of school district quality on home prices, and the appreciation of commercial real estate after improvements in public safety.

However, this cycle is not without limits. If property taxes grow too quickly, they may push out some residents, especially seniors on fixed incomes and low-income families, leading to changes in community demographics and even weakening the stability of the tax base. In addition, positive feedback depends on the assessment system being able to reflect market changes in a timely manner, while many jurisdictions, under political pressure, adopt lagged assessments or caps on increases, which instead interrupts the linkage between tax revenue and public services. Understanding this mechanism helps clarify the fundamental contradiction in the demand for "rising home prices, falling tax burden": the very positive feedback it seeks to cut off is precisely the core driving force maintaining community quality and property values.

Assessment Mechanisms and the Tax Rate Game

In reality, property tax calculation involves two variables: assessed value and tax rate. Homeowners' dissatisfaction with their tax bills often translates into appeals against assessment results. When a large number of homeowners believe valuations are too high, assessment agencies come under pressure, potentially leading to systematic undervaluation, or to mechanisms such as legislated valuation caps and limits on increases. California's Proposition 13 is a typical case: it limits annual increases in property taxes, resulting in extremely low tax burdens for long-term homeowners while new buyers bear higher taxes, creating unfairness between generations and groups.

This mechanism protects older homeowners in the short term, but it compresses local fiscal flexibility and reduces housing market liquidity—because low tax burdens make older homeowners reluctant to sell, and reduced supply pushes prices even higher. A policy that appears to protect homeowners may ultimately worsen housing affordability.

California's Proposition 13 was passed by referendum in 1978 and is one of the most influential property tax limitation laws in the United States. Its core provisions include: locking a property's assessed value at its 1975 base level, with annual increases thereafter not exceeding the lower of the inflation rate or 2%; reassessing at market value only when the property changes hands or undergoes major renovation; capping the property tax rate at 1% of assessed value; and requiring a two-thirds voter majority for any tax increase. While this system protects long-term holders from sharp tax increases, it also creates serious horizontal inequity: two neighboring properties of similar market value may have tax bills differing by several times because they were purchased at different times. It is estimated that this proposition costs California local governments tens of billions of dollars annually, forcing school districts to rely more on state transfers and bonds.

Valuation caps and increase limits are another common tool for restraining property taxes. Unlike directly freezing assessed value, such mechanisms usually allow valuations to rise with the market but set a maximum annual increase (such as 3% or 5%), making tax burden growth lag behind home price growth. The short-term effect is to ease homeowners' cash flow pressure, while in the long term it causes the effective tax rate to decline with the length of ownership. This institutional design also affects housing market liquidity: when the low tax base held by older homeowners cannot be transferred to new buyers, a "lock-in effect" emerges—even if family structure changes or work location shifts, homeowners are more inclined not to sell, because moving means a sharp jump in tax burden. Reduced supply in turn pushes up home prices, forming a "tax limitation—reluctance to sell—price increases" cycle.

Who Is Paying for the "Tax Cut"?

In the Hacker News discussion, many comments pointed out that taxes do not disappear into thin air; they only shift. The portion by which property taxes are reduced often must be made up through sales taxes, income taxes, state transfers, or cuts to public services. For local governments that rely on property taxes, budget cuts mean layoffs, reduced maintenance of public facilities, and delayed infrastructure projects—costs that residents ultimately bear in other forms.

More subtly, the wealth effect from property appreciation mainly benefits homeowners, especially early buyers; while tax burden shifting may put greater pressure on renters, new immigrants, and young families. A tax cut demand that appears universally beneficial may have highly unequal distributional effects.

Tax incidence is a key concept for analyzing the distributional effects of tax cuts. It distinguishes "statutory incidence"—who is legally responsible for paying the tax—from "economic incidence"—who actually bears the burden. The economic incidence of property tax is especially complex: part of the burden may be passed on to renters through higher rents, part may be borne by sellers through lower home prices, and part may be shared by all residents through cuts in local government services. When property taxes are cut and public services shrink accordingly, renters and low-income families who depend on public services often suffer the most, because they lack alternative resources (such as private schools or private security).

The wealth effect explains why property appreciation means fundamentally different things to different groups. For those who have already bought homes, especially early buyers, rising prices mean increased net worth that can be realized through refinancing, selling, or credit lines; for those who have not yet bought, the same price increases mean higher down payment thresholds and greater monthly payment pressure. When tax cut policies further favor long-term holders, the wealth gap between generations may widen: the older generation enjoys a low tax base and appreciation gains, while the younger generation faces high home prices, high tax burdens, and fewer public services. This distributional consequence reminds us that in evaluating any property tax policy, we cannot look only at the average tax burden, but also at who benefits and who pays.

Rationally Viewing the Relationship Between Real Estate and Tax Burden

For ordinary homeowners, what truly deserves attention is not the impossible triangle of "valuations up, tax burden down," but the efficiency and fairness of tax use. If public services are transparent and efficient, property tax can be seen as an investment in community quality; if funds are wasted or distributed unfairly, homeowners' dissatisfaction has a stronger basis.

At the policy level, more feasible directions include: setting reasonable tax rates and assessment cycles, providing relief or deferral options for low-income homeowners, and ensuring that the assessment process is open and transparent. These measures can ease homeowners' tax burden anxiety without undermining the fiscal foundation.

A home is both an asset and a burden, and property tax is the link connecting personal wealth and public services. Understanding the trade-offs involved is more practically meaningful than simply pursuing "the best of both worlds."

One-line Summary

Homeowners want both rising home prices and falling property taxes, but the two are fiscally contradictory, and tax cuts ultimately require someone to pay.

Paragraph Summary

The article analyzes from an economic perspective the seemingly reasonable yet self-contradictory demand of "rising home prices and falling property taxes." Property tax is a major funding source for local public services. Rising home valuations usually mean improved community quality, and public service investment in turn supports home prices, forming a positive feedback loop. Forcibly lowering tax rates or limiting valuation increases may ease homeowners' burdens in the short term, but in the long run it may lead to shrinking public services, reduced fiscal flexibility, and even undermine home prices. California's Proposition 13 is an example: it protects long-term holders but creates tax unfairness between old and new homeowners and suppresses housing liquidity. Taxes do not disappear; they only shift. Cutting property taxes often means raising other taxes, reducing services, or making renters and young families bear more costs. The article ultimately points out that a more feasible direction is to improve the efficiency and fairness of tax use rather than pursuing the best of both worlds.
