What’s the Difference Between Market Value and Tax Value?

If you’ve ever compared your home’s Zillow estimate to your tax statement, you’ve probably noticed a big difference. That’s because market value and tax value serve completely different purposes—and rarely align.

In Lubbock County, both numbers matter, but for very different reasons.

Let’s break it down.

1. Market Value — What Your Home Could Sell For
The market value is the price a ready, willing, and able buyer would likely pay for your home in today’s market. It’s driven by demand, comparable sales, neighborhood trends, and condition.

As a Realtor, I analyze market value using local MLS data, recent sales, and active listings. This number shifts constantly—rising with neighborhood growth or new amenities, and dipping when supply outpaces demand.

Simply put, market value reflects real-world buyer behavior.

2. Tax Value (Assessed Value) — What the County Thinks It’s Worth
The tax value, also called the assessed value, is what the Lubbock Central Appraisal District (LCAD) uses to calculate your property taxes.

LCAD conducts annual appraisals to assign a taxable value based on recent area sales and property data. However, these assessments often lag 6–12 months behind current market conditions.

That’s why your tax value may be lower—or occasionally higher—than your home’s actual selling potential.

3. How the Two Interact
While market value affects your sale price, tax value determines your annual property tax bill.
And here’s where homeowners get some leverage: if your assessed value climbs too high, you can file a protest in the spring to challenge it.

I help clients prepare those protests using true market data—recent Lubbock comps, adjustments for upgrades, and neighborhood trends—to argue for a fairer taxable value.

4. Quick Example:

• Market Value: $375,000 (what buyers would pay today)

• Tax Value: $340,000 (what LCAD uses for taxes)
  You’d pay property taxes on $340,000—not $375,000.

That difference doesn’t mean the county undervalued your home—it just reflects different goals: market value to sell, tax value to fund public services.

Understanding both helps you make smarter financial decisions—whether you’re pricing your home to sell or keeping your tax bill in check.

And in Lubbock, where property values shift fast, staying aware of both numbers means staying one step ahead.
