How to Build an Auction Platform for Real Estate

Today, online real estate auction platforms have replaced what used to be small halls full of people screaming the prices they are ready to pay for homes and properties.

What’s more interesting is that real estate auction platforms are continuing to grow. In 2002, 30% of all of eCommerce transactions were performed by online auction users.

In 2017, the overall profit of online home auctions reached $394 billion, which was an annual growth of 13% in comparison to previous years. So how to build a real estate auction site? And is it worth doing now? In 2020, the U.S. Industry Statistics & Market Research forecast that the industry will only continue to grow during the next 5 years.

Types of Real Estate Auction Platforms

Before starting the development process, it’s worth checking out the key online real estate auction types of platforms for home buying gathered below:

Increment Auction

Increment allows people to increase the price only by a certain number. In simple words, the increment is a minimum amount that can be raised each time. This is one of the most popular types of online home auctions.

Reserve Price Auction

Reserve price lets the sellers set their minimum for the price they need for the property.

In most cases, this price is hidden, therefore buyers can only see whether the price has been met or not. Once it’s met, the highest bid wins the auction.

Automatic Auction

At automatic auctions, the buyers set the highest price they’re willing to pay for the item. Then, the system bids on the buyer’s behalf automatically. If another bidder places a higher bid, the previous bidder will be outbid.

How Does a Real Estate Auction Platform Work? User Roles

Real estate auction platforms usually have three user roles: sellers, buyers, and moderators.

The first two – sellers and buyers – are the roles of the customers on the auction platform. The third is the auction platform itself, which acts as a moderator for buyers and sellers. Let’s take a closer look at each user role.


On the real estate auction platform, the sellers could be homeowners, real estate agents, real estate investors, or asset managers.

Buyers can be users who are purchasing properties for their own purposes. At the same time, buyers can be real estate brokers, agents, or real estate investors who buy a property to sell it later for a profit.

How to Build an Auction Platform for Real Estate: features for buyers

Platform Owner as the Moderator

A moderator of a home auction platform can manage the work of the platform. These kinds of users and investors are responsible for handling transactions, sale and purchase management, consulting investors, verifying or blocking users, etc.

Types of Properties Listed on Auction Platforms 

Different online home auctions work with different real estate types. In the paragraph below, we have gathered the most popular types of homes and properties that can be listed on an online real estate auction.

Short-Sale Properties

A short sale is a property purchase initiated by a distressed homeowner in an attempt to sell their house for less than the outstanding mortgage on it.

With short-sale homes and properties, both the lender and the borrower get their benefits.

For example, the lender avoids having to repossess the property in foreclosure, while the borrower avoids ruining their credit and, in some cases, bankruptcy.

Foreclosed Properties

Foreclosure is the legal process by which a lender attempts to recover the amount owed on a defaulted loan by taking ownership of and selling the mortgaged property.

A foreclosure property sale is a purchase that is forced by a lender. A foreclosure is usually the final step of a lengthy pre-foreclosure process, which is typically aimed at finding alternatives for both the lender and borrower to avoid possible negative consequences associated with this legal process.

Bank-Owned Properties

Bank-owned properties are homes and properties that were taken into a bank’s ownership after the failure of a foreclosure sale purchase.

Apart from being represented on real estate auction platforms, such properties are also easily accessible for sale on banks’ websites.

As usual, bank-owned homes and properties are sold at discounted prices, which makes them attractive opportunities for real estate investors.

Flipped Properties

This kind of real estate consists of investor-owned homes and properties that have been fixed up. After being renovated, these upgraded homes and properties are put up for sale.

For example, such housing is usually popular as the first-time home purchase among the buyers.

Retail Properties

This type of property is popular for sale among business owners and investors. 

For example, real estate homes and properties are usually used for shopping centers, stores, and other business buildings. 

8 Must-Have Features of a Real Estate Auction Platform

Before starting a real estate auction platform development, it’s crucial to determine its core functionality needed for an MVP, the first version of the product.

Below, we describe the most important features any online auction should have.

User Registration

User Account Creation

All online home auctions need their users and investors to register and create a personal profile. Such an approach helps to identify the users and provide smooth communication and cooperation within an auction platform.

As usual, the registration process requires users to specify personal information such as:

  • name
  • street address
  • zip code
  • phone number
  • email address
  • links to social networks

For some categories of users, such as investors, agents, and asset managers, an auction platform may also need the following data:

  • title
  • company name
  • real estate license number
  • real estate license state

Registering for Home Auctions

Once the user is registered to an auction platform, they can start searching for properties they’d like to buy. However, in order to actually start bidding, the users are required to provide their credit or debit card information.

This information is needed for all payments associated with the platform’s services, including fees and property purchase. To enable online payments, it is also important to integrate payment processing software into the real estate auction platform.

This feature allows the sellers to create a new property listing. The sellers should also be able to edit the information about the property after it’s created.

Notes and Disclaimers

Real estate home auctions have to deal with lots of legal rights and obligations. Therefore, such services can offer notes and disclaimers that inform the users about the possible legal details.

For example, notes and disclaimers offer customers details about property occupation or payment conditions.

3D Tours

Using modern technologies such as virtual and augmented reality is a trend that allows the creation of 3D tours for the real estate industry.

Used in online auction platforms, these modern real estate approaches help property buyers to take a virtual tour of the property to get a better understanding of its layout, size, and interior design.

Search and Navigation Features

Search and Filters

Search is a must-have feature for a real estate auction website. However, it is also important to include filtering so the users can also specify the property details.

Such an advanced search allows the users to narrow the search down by filtering out the properties by specific criteria such as:

  • location
  • number of bedrooms
  • footage
  • amenities
  • price range
  • asset type, etc.

  • remaining auction time
  • property price
  • property size
  • auction date
  • popular properties
  • new properties

Recently Viewed Properties

The recently viewed property feature helps the users to go back to search results they viewed earlier and return to properties they viewed before.

It is convenient when a real estate auction platform allows adding properties to favorites.

Relevant Recommendations

All the searches performed by buyers can be saved in order to create personalized recommendations for each user based on their previous searches.

This feature helps to provide smoother communication between the users and the platform, and improves the user experience in general.

Property Bidding

Countdown Timer

On real estate auction platforms, the bidding process usually takes 2-3 minutes. To control this time, the services implement the countdown clock feature, which helps to track this time.

If a buyer bids before the time runs out, then the clock resets. If no one bids before the time runs out, then the last bid wins the property.

How to Build an Auction Platform for Real Estate: timer

Hubzu Countdown Timer Feature

Automated Bidding Process

This feature helps a buyer to bid even if they’re currently away from their computer. The automated bidding software automatically places a bid on behalf of a buyer.

For example, such software allows a buyer to remain the highest bidder and win an auction, even if they are currently not able to participate in the bidding process.

Buy It Now Functionality

The BIN (Buy It Now) functionality allows sellers to set the particular price they’d like to sell a property for. Therefore, when the price reaches the number set by the seller, the property is sold automatically to the buyer.

At the same time, the buyer can buy a property immediately by bidding the seller’s desired price at the very start of the bidding process on an auction.

Auction Calendar

Auction calendar is helpful when it comes to tracking and choosing the upcoming real estate auctions.

This feature helps the users to search for the new auction events using filters such as:

  • event name
  • start or end dates
  • location
  • asset type

It’s convenient when the buyers can not only search for the properties, but also save the ones they are most interested in for easy access and a better user experience.

With such a feature, the buyers won’t have to search for the same property twice.

When creating a real estate online auction platform, it is important to make sure that the buyers can conveniently place bids. For example, a convenient dashboard for the property and bidding management can be a great bidding solution.

Reports and Analytics

A good real estate auction platform should provide its buyers and sellers with statistical reports and analytics. As a result, the people who bid can use this feature to analyze the data, provide an effective analysis of their auction activities, and buy a property.

Property Notification Emails

The users of a real estate auction platform should be able to receive notifications about the platform’s news and activities.

All in all, such messages can be sent by email and contain information about new properties, outbid notices, contract questionnaires, high bid confirmations, documentation, platform updates, news, etc.

Essential Mobile Features

Nowadays, over 76% of internet users look for a property for sale using their mobile devices. That’s why it’s important to think about the mobile features of the future real estate auction platform.

In this paragraph, we’ll describe the most crucial mobile features of an online auction service.

  • Push Notifications

No mobile application can survive without notifications. For real estate auction mobile applications, it’s crucial to provide alerts as they inform users about upcoming sales, new listings, fresh bid properties, and other news.

With this feature, the users will never miss an opportunity to find and bid on a property.

  • Determining Location

By being able to determine a user’s location, a mobile app can send appropriate property recommendations.

In addition, it makes it possible for users to search by their current location, choose a specific address, or use a mobile map.

  • Social Sharing

With this feature, mobile users are able to share the properties they like using text messages and social media. By doing so, the users can save the properties they like or share them with other people that may be interested in participating in the auction too.

  • Real-Time Bidding

With real-time bidding, the users will be able to place their bid and check already existing ones placed by other buyers in real time, without having to wait to close the bid.

Lots of users like to share properties with their friends, colleagues, family, or agents. An in-app messaging system ensures that users can share their favorite properties right away and receive replies without leaving the app. This is especially convenient, and such a messaging system provides a better user experience.

Monetization Models of a Real Estate Auction Platform

Sellers shouldn’t be the only people who get to make money on your platform.

If you are planning to monetize your real estate auction software and make money with it, we suggest checking out the most commonly used revenue models, which we’ve gathered in our article.

Listing Fee for Sellers

Some real estate auction platforms ask their sellers for an additional fee for each property they list. Usually, fees can be calculated as a percentage of the property price. Such fees are non-refundable regardless of success.

Premium Fee for Buyers

Usually, the real estate auction platforms requires the final buyer to pay a fee to close the bid and buy the property. Such a commission is paid to the platform for connecting buyers and sellers, and usually ranges from 5 to 10% of the overall cost.

Closing Transaction Fee for All Users

Some real estate auction platforms requires only sellers to pay a fee before they can auction a property. At the same time, there are platforms that take fees from both sellers and buyers.

Such a fee can be requested as an additional payment or be added to the final price of the property once the auction is finished.

Transfer Tax

The transfer tax fee is paid when the title of the property is transferred from the seller to the winner once the bidding is closed and the auction is over.

This tax is stated in the purchase and sale agreement, so the buyer has the opportunity to take it into account before the bidding is closed.

Tax rates depend on the location of the property. For example, there are different transfer tax rates in various US states.

Tips on How to Build a Real Estate Auction Platform Successfully

Conducting Market and Competitors Research

It’s always a good idea to start a product development process by conducting market and competitor research. At Sloboda Studio, we recommend conducting a discovery phase before the development stage for a deeper analysis of the product idea, requirements, and evaluation of the possible challenges and solutions.

As usual, a discovery phase helps to determine different aspects of the future product development, such as:

  • Niche
  • Core goals
  • Product features
  • Technology stack
  • Platform architecture
  • Suitable scope
  • Customer pain points
  • Challenges or limitations
  • User journey
  • Wireframes

Creating a Unique Value Proposition

Competition in the real estate online auction market is high, so it’s important to create a real estate auction website with a unique value proposition to stand out from the competitors. For example, real estate auction platforms can use financing and bridge loans to attract more buyers to bid.

Bridge loans are a type of short-term financing that help homeowners to buy a new home before selling their current one. With a bridge loan, the existing home is collateral. Bridge loans can be used to pay for the down payment, bid closing costs, or the remaining balance payment on the existing mortgage.

Deciding on the Type of Development 

Lots of people ask themselves: How can I create my own real estate auction site? Should I choose in-house development or outsourcing?

Sometimes it’s not that easy to find a quick answer.

Inhouse development helps product owners to stay in control: they work along with the team, make decisions together, and have the ability to check the results of the work once it’s ready. However, in-house development takes more time and resources for control, recruitment, hiring HR specialists, and rent.

Outsourcing gives less personal control, which, at the same time, can be backed by project managers who may work as mediators between product owners and the team. At the same time, outsourcing does not need a lot of additional resources such as time and money.

MVP Development and Product Launch

So how do you develop a real estate auction business? Starting the development process with an MVP – minimum viable product – usually saves a lot of time and money when you need to launch fast.

The MVP version of the future product includes only the core product features and doesn’t need as much money to implement as a fully-featured product would.

Therefore, an MVP is the best way to implement an idea into a real project that is ready to be represented to the audience or investors.

Ensuring User Security 

  • ID Verification

To make a real estate auction platform a trusted place, it is better to conduct an ID verification of each user. Such a practice helps to make sure that all the users are real people, and doing so prevents fraud.

Therefore, requesting a credit card number and ID data should be one of the steps of user account verification.

  • Real-Time Auction Tracking

An ability to track all the currently placed bids and receive all the bid updates helps the customers to control the current auction situation, react to changes faster, and receive all the actual bid information about their bidding and bidding placed by other participants.

Therefore, this feature allows users to track their current bid activity, which makes the work more transparent.

A good auction platform should provide its users with a rating system to create listings of trusted sellers, which increases transparency.

Reviews help to make a real estate auction platform a trusted place. Thus, if the real estate auction service can provide its customers with true and relevant feedback and bid information, this will grow the trust significantly and allow it to attract new users.

  • Trusted Listings

It’s important to make the property listings as trusted as possible. Buyers want to know as much as possible about the properties they search for, so it would be nice to include all the necessary information such as detailed descriptions, clear photos, and all the required documentation.

Getting Customer Feedback

Once the product is launched, its development process isn’t over yet. At this stage, it’s important to analyze the feedback: the users of the project may share valuable thoughts about what works great, but also give some important ideas on what to improve or add to make it even better.

Therefore, after getting users’ feedback, it’s important to fix everything that needs to be fixed.

Our Experience


This project is an Airbnb-like startup headquartered in Belgium. At the very beginning of our collaboration, Moovle needed our team to turn the idea of their project into an MVP product that was planned to be represented to the investors.

In particular, Sloboda Studio had to implement all the core features, integrate the external APIs for listing synchronization, as well as the listing management mechanism as a whole.

In addition, we had to work under a tight schedule of 1.5 months, so that our client could present the solution to investors.
