Could Your Split-Level or Bi-Level Home Be Over-Assessed?

In Western Pennsylvania, split-level and bi-level homes are sometimes over-assessed due to how square footage is recorded in county property records.

The issue usually involves below-grade space.

What’s the Problem?

Professional appraisal standards distinguish between:

• Above-grade living area (valued higher)

• Below-grade finished space (valued differently)

With split-level and bi-level homes, portions of the lower level may be partially or fully below grade but are sometimes recorded as above-grade in assessment data. When that happens, the home can appear larger on paper than it truly is.

Why This Affects Your Taxes

If below-grade space is incorrectly counted as above-grade:

• Recorded square footage may be inflated

• Assessed value may exceed similar homes

• Property taxes may be higher than warranted

This is a classification issue—not a claim that finished space has no value.

How an Appraisal Helps

A property-specific appraisal can:

• Measure the home using accepted standards

• Separate above-grade and below-grade areas correctly

• Provide credible support for a tax appeal

Should I Appeal My Property Tax Assessment?

A tax appeal may be worth exploring if several of the following apply to your property:

Review Your Property Record

☐ The county record lists more above-grade square footage than your home actually has
☐ Finished basement or lower-level space appears to be counted as full living area
☐ Your home style is split-level, bi-level, or split-entry

Compare to Similar Homes

☐ Similar homes in your neighborhood have lower assessed values
☐ Nearby properties of similar size and age have lower tax bills
☐ Your assessment seems high compared to recent sales of similar homes

Look at Your Home’s Characteristics

☐ Your home is older or has limited updates compared to higher-assessed properties
☐ The layout or design is less typical for the area
☐ Your home has functional limitations that buyers react to

Review Market Information

☐ Recent comparable sales suggest a lower market value than the assessment implies
☐ Your assessed value exceeds what homes are actually selling for

Consider Professional Support

☐ You haven’t had a recent appraisal that verifies square footage and condition
☐ You want independent, defensible evidence rather than estimates or assumptions

If you checked three or more boxes, a professional review or appraisal may help determine whether a tax appeal is appropriate.

Not every assessment error leads to savings—but inaccurate data often does.

Why the Appraiser Isn’t Coming — and Why That’s Okay

If you’re expecting an appraisal and learn the appraiser won’t personally visit your home, it’s normal to have questions. In Pennsylvania, this can be a legitimate part of the appraisal process and does not mean anything is being skipped.

In some cases, the appraiser sends a property data collector to gather information, while the licensed appraiser completes the valuation analysis separately.

What a Property Data Collector Does

A property data collector gathers objective facts, such as:

• Measuring the home

• Taking interior and exterior photos

• Recording room layout and visible features

They do not determine value or analyze the market.

Why You Should Still Take the Visit Seriously

Even though the appraiser isn’t there in person, the information collected is critical. Homeowners should:

• Allow full access to the property

• Point out updates or improvements

• Share any information that may not be obvious from photos

Accurate data leads to a stronger appraisal.

What the Appraiser Still Does

The licensed appraiser remains fully responsible for the appraisal. They:

• Review and verify all collected data

• Analyze comparable sales and market conditions

• Apply professional standards

• Determine and sign the final value

Why This Is Done

Separating data collection from analysis allows appraisers to focus on research and valuation. It can also reduce scheduling delays and improve turnaround times. Importantly, appraisal standards and accountability do not change.

Does This Affect Value?

No. The value conclusion is still based on verified data and recent comparable sales—not on who visited the property.

Bottom Line

Seeing a data collector instead of the appraiser does not reduce the quality of the appraisal. The appraiser remains responsible for accuracy, analysis, and conclusions. What matters most is that the information collected is complete and accurate—not who holds the measuring tape.
