The Best Real Estate Websites for Sellers, Compared
7 min read
The short answer
Zillow, Realtor.com, Redfin, Trulia and Homes.com are built to show listings to buyers, and Redfin and Opendoor will also handle the sale itself. Kelley Blue Book Homes produces a free valuation report designed to land within 3% of your final sale price and connects you with a local agent who has read it. An automated estimate is a starting point, and a report that accounts for your home's condition and upgrades is what you price a listing around.
If you're getting ready to sell, the best real estate websites are the ones that answer the question you actually have, and for most sellers that question is what the house is worth. Nearly every homeowner starts the same way, by typing an address into a search box, looking at the number that comes back, and then wondering how much of it to believe.
The sites that come up in that search were not all built for the same job. Most of them exist to show listings to buyers, a couple of them are brokerages that would like to have your listing, and one of them buys houses outright. Kelley Blue Book Homes does something different. It produces a free valuation report and connects you with a local agent who has read it before you ever talk.
We'll cover what each site is built to do, what it costs you, where it stops, and which one to open first depending on why you're selling.
How the Best Real Estate Websites Compare for Sellers
Every site in the table does one of three jobs. Listing portals are built for reach, brokerages and cash buyers have a position in your sale, and valuation services produce a number and explain how they arrived at it. It helps to know which job a site does before you decide how much to trust its number.
| Site | What it's best for | Cost to the homeowner | What it does not do |
|---|---|---|---|
| Zillow | A large audience of browsing buyers and a familiar automated estimate | Free to browse | Does not represent you in the sale or inspect your home for its estimate |
| Realtor.com | Listing data sourced from MLSs | Free to browse | Does not represent you in the sale |
| Redfin | Shopping listings and hiring a Redfin agent in markets Redfin serves | Free to browse; agent fees apply if you list with Redfin | Does not represent you unless you hire a Redfin agent |
| Trulia | Neighborhood detail such as schools and commute, on Zillow Group data | Free to browse | Does not publish a separate valuation product for sellers |
| Homes.com | Finding the agent who listed a property | Free to browse | Does not give you an independent number for your own home |
| Opendoor | A fast cash offer with a chosen closing date | Free to request an offer; fees disclosed in the offer | Does not give you an independent second number to weigh the offer against |
| Kelley Blue Book Homes | A free valuation report built on appraisal-grade methodology, designed to land within 3% of the final sale price, plus a vetted local agent who has read it | $0, no obligation | Is not a lender appraisal and cannot be used for mortgage or lending transactions |
What Each Site Is Built For
Zillow is where many buyers look first, and that reach matters to you as a seller because your listing will show up there through your agent's MLS feed. Its automated estimate is a starting point for your own number.
Realtor.com is operated by Move, Inc., and its listings come from MLS feeds, which makes it a useful place to check whether a neighbor's house really closed. It doesn't represent you in the sale, so vet any agent it shows you separately.
Redfin is a licensed brokerage that also runs a consumer site. You can browse listings, look at sold data, and hire a Redfin agent in the markets where Redfin operates. Keep in mind that agent fees apply if you list with Redfin.
Trulia is part of Zillow Group, and it layers neighborhood detail such as schools and commute times onto the map. If you're relocating, it's a reasonable first stop for the buying half of the move, though it doesn't publish a separate valuation product for sellers.
Homes.com is owned by CoStar Group and is handy for scouting which agents actually list homes in your neighborhood. It doesn't give you an independent valuation of your own home.
Opendoor buys homes directly and lets you choose the closing date, with its fees and any repair deductions disclosed in the offer itself. If you need to close on your next home before the old one sells, a certain date can be worth real money. In select markets, you can get a cash offer alongside a free Kelley Blue Book Homes valuation report and judge the two side by side.
How Kelley Blue Book Homes Differs From a Listing Site
Kelley Blue Book Homes is backed by Kelley Blue Book, the trusted partner for automotive valuations for 100 years, and powered by True Footage, a national appraisal company trusted by lenders and real estate professionals, with 500,000+ homes analyzed and $275B+ in properties valued. The free report is ready in minutes, carries no obligation, and is designed to land within 3% of the final sale price.
The difference is what goes into it. An automated model works from public records and past sales, so it has never seen your new roof, your 2019 kitchen, or the fact that your lot backs onto a greenbelt while your neighbor's backs onto a road. With Kelley Blue Book Homes, you answer questions about condition, upgrades, layout and remodels, and the report combines those answers with real comps from your actual neighborhood, with every adjustment explained. If you want to see how online estimates are built and where they miss, we've laid that out on its own page. Every report also connects you with a vetted local Kelley Blue Book Homes agent who has read your valuation before your first conversation. Keep in mind that the report is not a lender appraisal and cannot be used for mortgage or lending transactions.
Which Site Should You Use First?
That depends on why you're selling.
- If you're selling to move into a smaller home, start with the valuation, because that number drives everything after it, including what you can afford next.
- If you're settling an estate, start with the free valuation report so the whole family is working from one number for what the house could sell for. If a filing or the heirs need a formal appraisal, that is a separate job for a state-licensed appraiser. Confirm what's required with a tax professional or an attorney, since the IRS treats the basis of inherited property differently from property you bought (IRS Publication 551, 2024).
- If you're dividing property in a divorce, both parties usually want a number that neither one of them chose.
- If you're relocating, use a portal for the market you're moving to and a valuation for the house you're leaving.
- If you're just curious about your equity, a free automated estimate gives you a rough idea, and the free Kelley Blue Book Homes report gives you the number along with the comps behind it.

Key Points to Remember
- The best real estate websites do one of three jobs. Listing portals give you reach, brokerages and cash buyers have a position in the sale, and valuation services produce a number.
- Automated estimates rely primarily on public records and automated models, so they never see your condition and upgrades.
- A cash offer can only be judged against an open-market number, so get both before you decide.
- The Kelley Blue Book Homes valuation report is free, ready in minutes, and designed to land within 3% of the final sale price.
Frequently asked questions
What is the best real estate website for finding out what my home is worth?
For a rough figure, the major listing portals publish free automated estimates, and any of them will do. For a number you can actually price a listing around, use a valuation service that accounts for your home's condition and upgrades. The Kelley Blue Book Homes report is free, ready in minutes, and designed to land within 3% of the final sale price.
Is an online estimate the same as an appraisal?
No. An appraisal is performed by a state-licensed appraiser who inspects the property, and lenders order one for a mortgage, though homeowners can order a pre-listing appraisal too. Online estimates are automated models built from data. The Kelley Blue Book Homes report is built on appraisal-grade methodology, and even so it is not a lender appraisal and cannot be used for a mortgage or lending transaction.
Should I use a real estate website or a real estate agent to price my home?
The two do different jobs, so most sellers end up using both. A website gives you an independent number to start from, and a good local agent knows things no dataset captures, such as which streets buyers avoid and what sold off-market last month. Every Kelley Blue Book Homes valuation report comes with an introduction to a vetted local agent who has read your report before your first conversation.
