In a hypothetical example, a buyer sees a house listed for $340,000, an assessment record showing $180,000, and a lender appraisal of $320,000. Which number is the property’s value?
Before choosing, ask what each number measures. For Pennsylvania real estate students, understanding assessed value vs. appraised value vs. market value starts with the purpose, source, and date of the figure. A tax record, a lending report, and a seller’s asking price answer different questions.
The five terms to keep separate
- Market value: An estimate of what a property would bring in a competitive market with a willing buyer and willing seller, neither forced to act. It concerns specified market conditions and a particular point in time.
- Appraised value: An appraiser’s opinion of value for an identified property and assignment. In a typical home-lending assignment, the opinion estimates market value. Market value and appraised value therefore overlap: one describes the value being estimated; the other describes the opinion reached.
- Assessed value: The value assigned through the government’s property assessment process for taxation. Its relationship to current market value depends on the applicable assessment system.
- List price: The seller’s advertised asking price. A listing alone does not establish what a buyer will pay.
- Sale price: The amount paid in a completed transaction. Before closing, distinguish the agreed contract price from a completed sale.
Philadelphia’s OPA glossary distinguishes market value from sale price, while the Consumer Financial Protection Bureau explains appraisals as independent opinions of property value. A sale can provide evidence of market value without making every other valuation identical.
Why a Pennsylvania assessment may look surprisingly low
Do not assume every Pennsylvania county assesses property at its full, current market value. Under Section 8842 of Pennsylvania’s Consolidated County Assessment Law, counties covered by that law use an established predetermined ratio and may use current market value or a base-year market value. A base year ties the valuation framework to an earlier year rather than automatically updating it to today’s prices.
Consequently, comparing a listing with an assessment dollar for dollar can be misleading. A $180,000 assessment does not, by itself, show that a $340,000 asking price is excessive. First identify the county’s assessment basis, relevant year, and ratio. Also distinguish the total assessment from the taxable portion after applicable exclusions, exemptions, or abatements.
You may encounter Pennsylvania’s common level ratio (CLR). The State Tax Equalization Board’s FAQ explains its relationship to assessed and current market values and its role in assessment appeals. It is not a mortgage appraisal or a universal shortcut for pricing a house. Do not confuse it with the Department of Revenue’s separately presented CLR real estate valuation factors for realty transfer tax.
Philadelphia is a local example, not a statewide template
Philadelphia’s Office of Property Assessment FAQ states that properties are assessed at 100% of their market value. That describes Philadelphia’s assessment framework, not every Pennsylvania county.
OPA’s estimate still need not match a lender’s appraisal or a later sale price. The City’s assessment guidance describes factors such as property characteristics, condition, location, and comparable sales. A Notice of Valuation is not a tax bill. When an exemption or abatement applies, the taxable amount may differ from the total assessment.
What a lender appraisal tells you
A lender uses valuation information when evaluating the property securing a loan. Do not tell a client that every mortgage requires the same kind of appraisal: the CFPB says a lender may obtain a new appraisal or use other ways to check value.
Different opinions can also reflect different comparable sales, completion dates, or purposes. The CFPB’s explanation of differing mortgage valuations makes this distinction. If an appraisal is below the contract price, review the report and discuss financing and contract options with the appropriate professionals. Neither the asking price nor the tax assessment overrides the lender’s valuation decision.

One hypothetical property, several valid labels
These invented figures illustrate vocabulary only. They do not represent a particular county, property, assessment ratio, or tax bill.
- The seller lists the property at $340,000.
- A buyer and seller initially agree to a $330,000 contract price.
- A lender’s appraisal estimates market value at $320,000 as of its effective date.
- The existing assessment record shows $180,000 under an unspecified local assessment framework.
- The parties later renegotiate and close at $325,000, making that the sale price.
The $10,000 difference between the original contract price and appraisal does not tell you the buyer’s final cash requirement. Financing terms and any renegotiation matter. The example also provides too little information to calculate property taxes.
A practical checklist for students
- Name the source: Assessment office, appraiser, listing, or closing record?
- Check the date: Which assessment year, appraisal effective date, or sale date applies?
- Identify the purpose: Taxation, lending, pricing, or recording a completed transaction?
- Confirm the local framework: Never import one county’s ratios or procedures into another.
- Separate labels before calculating: Practice the arithmetic with our Pennsylvania real estate math guide.
Three self-check questions
1. Does an assessment below the asking price prove overpricing?
No. The assessment may use a different year or ratio. Investigate current market evidence and the assessment framework before drawing a conclusion.
2. Must Philadelphia’s assessment equal a lender’s appraisal?
No. Even when both aim to reflect market value, their dates, information, and methods may differ.
3. Is an agreed contract price already a completed sale price?
No. The transaction may change or fail to close. Label the contract figure accurately until the sale is completed.
