Why Online Estimates Aren't Enough for Estate Decisions
By a St. Charles County Licensed Residential Appraiser with More Than 26 Years of Experience
When a loved one passes away, one of the first questions families ask is:
"How much is the house worth?"
Today, it's tempting to type an address into an online home value estimator and assume the number is accurate. After all, it's fast, free, and available in seconds.
Unfortunately, when it comes to probate, estate administration, or inherited property, an online estimate is rarely enough.
Over the past 26 years, I've appraised thousands of homes throughout St. Charles County and the surrounding St. Louis area. I've seen online estimates differ from a property's actual market value by tens of thousands of dollars—and sometimes much more.
When important financial and legal decisions depend on a home's value, relying on an automated estimate can create unnecessary problems.
What Are Online Home Value Estimates?
Websites like Zillow, Realtor.com, Redfin, and others use automated valuation models (AVMs) to estimate a home's value.
These systems analyze public records, previous sales, neighborhood trends, and other available data to generate an estimated value.
While these tools can provide a general starting point, they are not a substitute for a professional appraisal.
An AVM has never walked through your home.
It doesn't know if the kitchen was completely remodeled last year or if the basement has water damage. It can't evaluate deferred maintenance, upgrades, workmanship, or the overall condition of the property.
Those details often have a significant impact on value.
Why Accuracy Matters During Estate Administration
When someone inherits a home, the property's value often influences several important decisions, including:
Estate administration
Asset distribution among heirs
Tax planning
Potential sale decisions
Buyout negotiations between family members
Financial planning for beneficiaries
An inaccurate value can lead to disagreements, unrealistic expectations, or costly mistakes.
Having a credible, independent valuation gives everyone involved a clearer understanding of the property's fair market value.
Every Home Is Different
Even two homes located next door to each other can have very different values.
Factors that influence value include:
Overall condition
Recent renovations
Quality of construction
Functional layout
Deferred maintenance
Lot characteristics
Location within the neighborhood
Current market conditions
Recent comparable sales
These are factors that cannot be fully measured by an automated algorithm.
A professional appraiser evaluates the property in person and analyzes how these characteristics compare with similar homes that have recently sold in the local market.
Estate Decisions Often Require More Than a Guess
When families are making decisions about inherited real estate, they deserve more than an estimate generated by software.
A professional appraisal provides:
An independent opinion of value
Detailed market analysis
Comparable sales data
Documentation supporting the conclusion
A report prepared according to professional appraisal standards
This information provides confidence when discussing options with attorneys, accountants, financial advisors, or other family members.
Common Misconceptions About Online Estimates
One of the biggest misconceptions I encounter is:
"Zillow says the home is worth $450,000, so that's what it's worth."
In reality, online estimates are just that—estimates.
Some properties may be reasonably close to market value, while others can vary significantly depending on the available data and the uniqueness of the property.
Inherited homes are especially difficult for automated systems because many have not been updated in years, while others have undergone extensive renovations that public records don't accurately reflect.
Why Professional Appraisals Help Families
During an emotional time, families often need reliable information—not assumptions.
A professional appraisal can help:
Establish fair market value
Support estate planning and administration
Reduce disagreements among heirs
Assist with financial and tax discussions
Guide informed decisions about whether to keep or sell the property
Knowing the property's true value allows families to move forward with greater confidence.
Local Experience Makes a Difference
Real estate markets vary from one community to another.
As a licensed residential appraiser serving St. Charles County and the greater St. Louis area for more than 26 years, I understand the local market, neighborhood trends, and property characteristics that influence value.
That local knowledge provides insight that national algorithms simply cannot replicate.
The Bottom Line
Online home value estimates can be a useful starting point, but they should never be the foundation for important estate decisions.
When an inherited property's value affects legal matters, financial planning, or family decisions, obtaining an independent professional appraisal is one of the smartest steps you can take.
Having accurate information today can help prevent confusion, disagreements, and costly mistakes tomorrow.
