Ever wonder why the number on your lender’s appraisal rarely matches the value on your property tax bill? You are not alone. In Kansas City, those two figures serve very different purposes and are calculated in very different ways. In this guide, you will learn what each value means, how they are set in Jackson County, and how to use them to make confident decisions as a buyer or seller. Let’s dive in.
Appraisal basics in Kansas City
An appraisal estimates a home’s current market value for a specific transaction. Lenders order appraisals during a financed purchase or refinance, but you can also order one for private reasons like pre-listing, estate planning, or divorce. Licensed or certified appraisers complete appraisals under professional standards and set an effective date, usually tied to the inspection or contract date.
For most single-family homes, appraisers rely on the sales comparison approach. They select recent, similar closed sales and adjust for differences in condition, upgrades, lot size, and features. In fast-moving neighborhoods or with unique homes, appraisers may have limited comparable sales, which can affect the final opinion of value.
Assessment basics in Jackson County
An assessment is the county’s value used to calculate your property taxes. In Kansas City addresses within Jackson County, the Jackson County Assessor sets this value. Unlike a single-home appraisal, assessments use mass appraisal techniques across many properties at once.
Assessors rely on recorded property data, building-cost schedules, and neighborhood-level sales trends. Because assessments follow county schedules and use broad models, they often lag current market conditions.
How values are calculated
Appraisals: on-the-ground analysis
- Appraisers inspect the home, verify condition, and document improvements.
- They use recent closed sales, usually from the last 3 to 6 months when available.
- They may apply cost or income approaches when appropriate, but for most homes the sales comparison approach is primary.
Assessments: mass appraisal models
- The assessor values many homes at once using standardized models and property records.
- Missouri converts market value to assessed value using a statutory ratio. For residential property, the assessed value equals 19 percent of market value.
- Reassessment occurs on a set schedule, so assessed values can trail current prices.
Why the numbers rarely match
- Purpose: An appraisal supports a specific sale or loan. An assessment sets your taxable value.
- Timing: Appraisals are transaction-timed. Assessments update on county schedules and may lag the market.
- Method: Appraisals are property-specific. Assessments use mass appraisal across neighborhoods.
- Statutory ratio: In Missouri, residential assessed value is 19 percent of market value, so the assessed number will look much smaller than an appraised price.
What this means for buyers
If you are using financing, your lender’s appraisal influences how much the lender will fund. When an appraisal comes in below the contract price, you may need to bring extra cash, renegotiate the price, or use an appraisal contingency to exit the contract. In neighborhoods with rising prices or limited comparable sales, appraisals can trail contract prices.
To prepare, understand your appraisal contingency and timelines. Make sure your agent shares recent comparable sales and a list of upgrades with the appraiser through the lender’s process. Keep documentation ready so the appraiser can verify the home’s features and condition.
What this means for sellers
A low appraisal can derail a deal or reduce your net. To lower that risk, consider a pre-listing appraisal or a thorough competitive market analysis. Price in line with recent closed sales and be ready to present a clear packet of comparable sales and improvement records to support your list price.
If an appraisal comes in below contract, you can provide additional data, negotiate price or concessions, or request a reconsideration of value through the buyer’s lender.
Taxes and the 19 percent rule
Your tax bill is based on the county’s assessed value, not a lender’s appraisal. In Missouri, the residential assessed value equals 19 percent of market value. That statutory ratio is why the assessed value is much lower than what you see in a sales appraisal or listing price.
A completed sale can influence future assessments depending on county schedules and policies. Review the parcel record to confirm details like square footage and improvements so the county has accurate information.
A simple example
- Market or appraised value: 350,000 dollars
- Missouri residential assessed value: 0.19 × 350,000 = 66,500 dollars
- Estimated tax using a sample combined rate of 1.00 percent: 66,500 × 0.01 = 665 dollars
Note that local tax rates vary. Check the county’s published rate when estimating your own bill.
Steps to take in a KC transaction
Before you list or offer
- Review the Jackson County Assessor parcel record for square footage, year built, and improvements. Correct obvious errors early.
- Study recent closed sales in the immediate area to set realistic expectations.
- Consider a pre-listing appraisal or a detailed market analysis.
When the appraisal is low
- Ask the lender about a reconsideration of value and provide additional comparable sales.
- Revisit price, concessions, or cash to close depending on your goals and contract terms.
For assessments and taxes
- If property details look incorrect, request an informal review with the county and follow appeal procedures if needed.
- Track deadlines for notices and appeals.
- Check eligibility for exemptions that can reduce taxable value.
Documentation that helps
- A packet of recent closed comparable sales with dates and photos.
- A list of renovations with dates, permits, and costs where available.
- Photos that show condition and unique features.
- Floor plans or independent measurements if county records differ.
When to seek a second opinion
If you face a large value gap or have a unique property with few comps, talk with your agent about ordering your own appraisal. For assessments, consider an appeal if your parcel data is wrong or if market evidence suggests an error in your assessed value. Stay within county timelines for any appeal steps.

- An appraisal is a property-specific opinion of current market value for a transaction, while an assessment is a county-set value used to calculate property taxes.

- Missouri applies a statutory ratio for residential property at 19 percent of market value to determine the assessed value, which is then used to compute taxes.
Why might an appraisal be lower than my contract price?
- Appraisers rely on closed sales, not list or pending prices, so in rising markets or with limited comps, the appraisal can trail current demand.
Do appraisals change my property taxes in Jackson County?
- No. Taxes are based on the county’s assessed value, not a lender’s appraisal, though a sale may influence future assessments depending on county schedules.
Can I challenge a low appraisal or an assessment I believe is wrong?
