Tips on How to Build a Real Estate Auction Platform Successfully

Conducting Market and Competitors Research

It’s always good to start a product development process by conducting market and competitor research. At Sloboda Studio, we recommend performing 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
  • Software 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 crucial 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 bids.

Bridge loans are short-term financing that helps homeowners buy a new home before selling their current one. With a bridge loan, the existing house as 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 

Many people ask themselves: How can I create my real estate auction software? Which hiring practice should I choose: in-house development or outsourcing?

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

In-house development helps product owners stay in control: they work with the team, make decisions together, and check the work results once they’re ready. However, in-house development takes more time and resources for control, recruitment, hiring H.R. 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 to build a real estate auction site with maximum benefits? 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 an actual project that can 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 ensure that all the users are real people, preventing fraud.

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

  • Real-Time Auction Tracking

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

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

  • Ratings

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

  • Reviews

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

  • Trusted Listings

It’s essential 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 crucial to analyze the feedback: the project users may share valuable thoughts about what works great and give some essential 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. 

How Long Does It Take To Build a Real Estate Auction Marketplace?

Based on our experience, creation of a real estate auction marketplace can take 3-6 months

We advise companies to use Python for the back and React for the front side of real estate auction development.

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

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

User Registration

User Account Creation

All online home auctions need users and investors to register and create a personal profile. Such an approach helps identify the users and provides 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 software 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 search for properties they’d like to buy. However, to start bidding, the users must provide their credit or debit card information.

This information is needed for all payments associated with the platform’s services, including fees and property purchases. Integrating payment processing software into the real estate auction platform is also essential to enable online payments.

Notes and Disclaimers

Real estate home auctions have to deal with many legal rights and obligations. Therefore, such services can offer notes and disclaimers informing users about 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 necessary if companies want to know how to build a real estate auction site. This trend allows the creation of 3D tours for the real estate industry.

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

Search and Navigation Features

Search, and Filters are must-have features for a real estate auction website. However, it is also vital 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.

Apart from the search and filtering, there should also be the ability to sort the search results by various criteria. For example, the search results can be sorted by:

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

Recently Viewed Properties

The recently viewed property feature helps users 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 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

The bidding process usually takes 2-3 minutes on real estate auction platforms. 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, the clock resets. If no one bids before the time run out, then the last bid wins the property.

Hubzu Countdown Timer Feature

Automated Bidding Process

This feature helps buyers bid even if they are away from their computers. The automated bidding software automatically places a bid on behalf of a buyer.

For example, such software allows buyers to remain the highest bidder and win an auction, even if they cannot participate in the bidding process.

Buy It Now Functionality

The BIN (Buy It Now) functionality allows sellers to set the special price for which they’d like to sell a property. Therefore, when the price reaches the number assigned 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

The 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

Reports and Analytics

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

Property Notification Emails

The real estate auction platform users should 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, software updates, news, etc.

Essential Mobile Features

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

This paragraph will describe the most crucial mobile features of online auction services.

  • Push Notifications

No mobile application can survive without notifications. Real estate auction mobile applications provide alerts as they inform users about upcoming sales, new listings, fresh bid properties, and other news.

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

  • Determining Location

A mobile app can send appropriate property recommendations by determining a user’s location.

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

Mobile users can share their properties using text messages and social media with this feature. The users can save the properties they like or share them with other people interested in participating in the auction.

  • Real-Time Bidding

With real-time bidding, the users will be able to place their bids and check existing ones placed by other buyers in real time without waiting to close the offer.

  • Messaging

Many 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 incredibly 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 plan 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, payments 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 require 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 require only sellers to pay a fee before auctioning a property. At the same time, some platforms take payments from both sellers and buyers.

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

Transfer Tax

The transfer tax fee is paid when the property’s title 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 U.S. states.

How Does a Real Estate Auction 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 which acts as a moderator for buyers and sellers. Let’s take a closer look at each user role.


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

Buyers can be users who are purchasing properties for their 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.

Platform Owner as the Moderator

A moderator of a home auction platform can manage the software work. These users and investors are responsible for

  • handling transactions
  • sale and purchase management
  • consulting investors
  • verifying or blocking users, etc.

Types of Real Estate Auction Platforms

Before starting to know how to build a real estate auction site, it’s worth checking out the critical 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 completed, 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.

Types of Properties Listed on Auction Platforms 

Different online home auctions work with various real estate types. We have gathered the most popular homes and properties listed on an online real estate auction in the paragraph below.

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 repossessing the property in foreclosure. 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. It’s possible by taking ownership of and selling the mortgaged property.

A foreclosure property sale is a purchase that a lender forces. A foreclosure is usually the final step of a lengthy pre-foreclosure process. It 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 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, making 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 a first-time home purchase among buyers.

Retail Properties

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

For example, real estate homes and properties are usually used for

  • shopping centers
  • stores
  • other business buildings
