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.

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 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.

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

8 Must-Have Features of a Real Estate Auction Platform

Before starting a real estate auction platform 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

  • 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:
