Property Taxes

Property Taxes (sometimes called 'ad valorem' taxes) are the fees you pay to local governments—like your city, county, or school district—just for the privilege of owning real estate. Think of it as a subscription fee for your property, one that funds public services like schools, police, fire departments, and road maintenance. The amount you owe isn't just plucked from thin air. It's calculated based on two key ingredients: the assessed value of your property (what the government thinks it's worth) and the local tax rate, often called a millage rate. For investors, particularly those following a value investing philosophy, property taxes are not just a minor nuisance; they are a critical, ongoing expense that can dramatically impact the long-term return of an investment, whether it’s a rental property or the stock of a company that owns a lot of buildings.

Property taxes are the silent partner you never wanted. They take a slice of your profits every single year without fail. Ignoring them is like trying to sail a boat while ignoring a hole in the hull. A true value investor must analyze them with the same rigor they apply to any other cost.

For anyone directly owning property, taxes are a major line item that directly eats into your cash flow. They are a core component used to calculate a property's Net Operating Income (NOI), which is simply the property's gross income minus its operating expenses.

• NOI = Gross Rental Income - Operating Expenses (including property taxes)*

Since the value of an income-producing property is often determined using a Capitalization Rate (Cap Rate), a higher tax bill means a lower NOI, which in turn leads to a lower property valuation. A sudden spike in property taxes can single-handedly turn a profitable investment into a money pit. Before buying any property, a diligent investor must investigate:

• Tax History: Has the tax bill been stable or has it been skyrocketing? Look at the past 5-10 years of tax records.
• Reassessment Schedule: When is the property due for a new assessment? A new, higher valuation after you buy could mean a shocking tax hike.
• Local Government Finances: Is the city or county in financial trouble? If so, they might be looking to raise property tax rates to fill budget gaps.

You don't have to be a landlord for property taxes to affect your portfolio. Companies with large physical footprints—think big-box retailers like Costco, industrial giants like Caterpillar, or, most obviously, Real Estate Investment Trust (REIT)s—pay immense amounts in property taxes. This expense appears on the company's income statement under operating expenses, directly reducing its pre-tax profits and, ultimately, its ability to generate free cash flow. A savvy stock-picker will read the footnotes in a company's annual report (the 10-K) to understand its exposure to property taxes. A geographically-concentrated company could be highly vulnerable if a single state or county decides to aggressively raise tax rates.

Property taxes are full of traps for the unwary. Keep an eye out for these common issues:

• Reassessment After a Sale: This is the big one. In many jurisdictions, a property’s assessed value is reassessed to the new, higher purchase price right after it's sold. The previous owner's charmingly low tax bill is not a reliable guide for what your future costs will be. Always calculate your potential tax bill based on your purchase price.
• Special Assessments: These are one-off taxes levied on property owners to pay for specific local projects, like new sidewalks, sewer lines, or streetlights. They can be a nasty surprise and add a hefty, unexpected cost on top of your regular tax bill.
• Comparing Apples to Oranges: Tax rates vary wildly between jurisdictions, even between neighboring towns. A property in Town A might seem cheaper than an identical one in Town B, but if Town A's tax rate is double, your total cost of ownership could be much higher. Always factor in the effective tax rate, not just the purchase price, when comparing investment opportunities.
