Best Home Value Estimator Sites [Top 5]

You might be about to make a significant financial choice about your home. Maybe you’re about to sell it because things have changed a lot in your family. Or, you could refinance your home to get a better rate on your mortgage. So how do you start?

One good place to start is to find out how much your home is worth. If you want to sell your home, a real estate agent can usually give you this information. If you are refinancing, a trained appraiser will give you this information.

But if you want to know, “How much is my house worth? You don’t have to talk to one of these professionals to get an estimate. You can start by using an online tool to find out how much your property is worth. Unfortunately, not all sites that estimate the value of a house give the same numbers. This guide will look at some of the best sites you can trust.

How to Choose the Best Home Value Estimator

Estimators of the value of a home are not all the same. Each site does a valuation using a different set of criteria and a different algorithm. When trying to answer the question, “How much is my house worth?” accuracy is critical, but there are a few other essential things to keep in mind.

Estimate Purpose

When selling or buying a home, getting a loan, or refinancing are some of the most common times for a homeowner to use a home value estimator site. Home value estimators can give estimates for homes that are for sale or not for sale. Some estimators will only tell you how much a home is worth, while others will tell you more about it, like how big it is and how many rooms it has.

Market Value vs. Appraised Value

When using sites that estimate the value of a home, keep in mind that the values they give are not market values. The market value of a house is how much it’s worth when it’s put on the market. It’s the price a buyer will pay for a person’s property based on how much they think it’s worth. This value could be more or less than what the market says it is worth. Online home valuation tools provide estimates that are not the same as appraisals. The appraised value of a home is based on several things, including how much other homes in the area have sold for recently. Sites that try to figure out how much a house is worth may look at the market value, the appraised value, and other factors. Still, the prices on these sites are just estimates that could change based on several factors.

Factors in Determining Home Value

So how do these sites figure out how much a house is worth? Each site gets its information from different places. The Multiple Listing Service (MLS), county records, and similar homes in the area are some of these sources.

Getting help from a real estate agent who will do a comparative market analysis is another way to determine how much a house is worth. This analysis is based on recent sales of other homes in the same area. In order to get an accurate estimate of a property’s value, another option is to employ a professional appraiser. An appraiser will charge you a fee for a much more hands-on home evaluation. Most of the time, an appraisal will cost between $300 and $400. But it can cost more than $1,000 for much bigger properties. Since these sites are free, they can be an excellent first step before paying for an appraiser’s services.

Accuracy and Median Error Rate

There are often problems with how accurate these sites are. There can be a discrepancy of up to 10 percent between online valuations and actual sales prices, depending on whether or not the property in question is actually for sale. Estimates will be more accurate for homes that are for sale or have recently been sold or for homes that have recently been added to the public record. Recent changes, like renovations, may not be considered in the valuation, which is a shame. It won’t be considered if you’ve done a major renovation, like adding a bedroom or bathroom but still need to update the public records. When users type in their addresses, these differences could lead them astray. Sometimes, it’s a good idea to use both a home value estimator and a remodeling estimator to figure out how much a home is worth.

Update Frequency

When using a site to estimate the value of your home, keep in mind how often the site updates its information. A property’s value may go up over time, especially if there have been recent improvements or significant changes in the area. A home could also lose value if it is old, has bad curb appeal, or has a low property tax value. Services with a lot of traffic and a good reputation that use strong listing sites will usually update more often. These sites may show the last time they were updated. Depending on its algorithms, a site that estimates the value of a home may update once a day, once a week, once a month, or at other times.


Some information about a house is available to the public, so a user can put in any address and find out about it. The results may show how much the house is worth and other essential facts about it. But if a user wants to know a lot about a particular property, this information is usually unavailable to the public. Users can see this information if they claim a property and set up an account on the site. With an active account, the user can log in and change the data already there. This gives much more accurate results.

Additional Tools

A property valuation tool is just one service provided by some websites. Users can buy and sell houses on some websites. In some, you can find dictionaries devoted to credit cards, mortgages, and schooling. If you are a homeowner thinking about renting out your property, there are websites that can help you with management and promotion. Users may be encouraged to consider additional services and/or goods after using the site’s various home value estimators.
