Online Home Estimate or Local Pricing Advice: Which Number Should You Use?

Use an online home estimate as a starting question. Before choosing an asking price, ask for a local pricing analysis that explains the number, the comparisons, and what still needs checking.
I wouldn't dismiss an online estimate just because it's online. I also wouldn't accept an agent's higher number just because it sounds better. Either way, ask what supports it.
If you're getting ready to sell in Mentor, Willoughby, Kirtland, or elsewhere in Northeast Ohio, here's how I'd work through the difference.

Start by checking what the website knows
Zillow says its Zestimate uses public records, MLS information, and details supplied by users. It also says the estimate isn't an appraisal. Incorrect or incomplete information can affect the result. [1]
Check the basic facts first: size, bedrooms, bathrooms, and any recorded changes to the house. If something looks wrong, identify the source of the difference before treating either number as correct.
Keep a screenshot with the date and any estimated range shown. That gives you something specific to discuss instead of trying to remember what the website said last month.
Don't change accurate facts just to push the estimate higher. The point is to understand the information behind it.
Ask the agent to show the reasoning
A comparative market analysis, usually called a CMA, uses comparable properties to help recommend a listing price. NAR's consumer guidance describes considering recent sales, homes under contract, and active listings, along with the home's size, location, amenities, and condition. [2]
I'd want the agent to explain:
Which homes are the strongest comparisons, and why?
What important differences did you account for?
What do we still need to verify about my house?
What would make you change your recommendation?
You don't need to become a valuation expert. You do need an explanation you can follow. A polished report with lots of addresses doesn't answer those questions on its own.
For the same reason, I wouldn't choose an agent solely because they suggested the highest asking price. Ask them to defend that recommendation with evidence.
If the numbers disagree, investigate the gap
Here's a made-up example, not a valuation of a local home: a website shows $300,000, while an agent suggests considering $280,000 to $290,000.
Don't split the difference automatically. Ask the agent to walk through the disagreement. Are the property facts different? Are the comparisons actually similar? Has the agent reviewed the house's current condition?
The lower recommendation isn't automatically more realistic. The higher estimate isn't automatically wrong. If neither explanation is convincing, get the missing facts or another opinion before deciding.
Keep asking price, appraisal, and proceeds separate
An asking price is the price you choose to offer the house for sale. NAR notes that the seller has the final say. A CMA helps inform that choice; it doesn't promise what a buyer will pay. [2]
An appraisal is an independent opinion of value. The CFPB explains that a lender may obtain one, or use other valuation methods, when evaluating a home loan. Don't assume a website estimate settles a future lender's decision. [3]
And sale price isn't what you keep. Use a seller's net sheet to compare possible proceeds after payoff and selling costs. That can help you decide whether selling works for your next move.
Bring the estimate to the conversation
Before paying for improvements or settling on a listing number, gather your screenshots, a short list of updates and known concerns, and your preferred timing.
If someone recommends repairs to support a higher price, ask what the work would cost and why it's worth doing. Our repair-or-sell-as-is guide helps you compare the options.
My advice: look for a recommendation you can understand and question. You shouldn't have to choose between trusting a website blindly and trusting an agent blindly.
