What Is a Real Estate Website?
Real estate websites bring convenience to buyers and exposure to sellers. Buyers can view hundreds of property images, videos, and features before they ever need to schedule a live tour. Sellers who post their homes on these sites benefit for the same reason; hundreds or thousands of prospective buyers can view their home online without needing to walk through. The other major purpose real estate websites serve is as a marketing channel for the professional service providers that contribute to the transaction. Realtors, mortgage professionals, banks, and inspectors can advertise on the website to generate leads.
How Do Real Estate Websites Get Data?
Real estate websites populate their inventory of homes in a variety of ways. In some cases the input is manual. A realtor or property manager updates a home’s profile or a seller uploads pictures. Other updates happen digitally through each company’s proprietary algorithm. The algorithm collects information from city and town tax databases and regional multiple listing services, to name a few.
Are Real Estate Websites Accurate?
Accuracy has been and still is the biggest challenge for real estate websites and their mobile apps. Some companies have improved their accuracy by validating the information collected by their algorithms using their own research staff. The websites have improved information refreshes from a few times per day to every 15 minutes, or in real-time in some cases.
Are There Fees for Real Estate Websites?
Most sites provide free services for the buyer or renter. The draw is to pull them in without barriers. Typically, however, if you want to use the full features, like saving your search criteria or getting push notifications when a property you are watching lowers its price, you’ll need to give the website your name and email address, and sometimes even your phone number. Once this is done, you may open yourself up to several phone calls and emails from websites charge sellers to list their homes for sale, or for property managers to communicate with their tenants through the app or website. If a renter wants to apply to an apartment through an app, they will have to pay for that convenience too.
How We Chose the Real Estate Websites
To choose the best seven, we reviewed 18 real estate websites. We uncovered their pros and cons, tested the search and sort capabilities, and dove into app reviews to see what people loved and what they wanted to see improved.
The companies’ reputations influenced our decision for the best as well. We studied and compared sites against each other to see which provided more information, how easy it was to find, and whether we can do it on the run in our mobile app.
Finally, we dug into how the website compiled information. Did it seek source data or did it glean it from another third-party site? And we looked at the money; how it’s earned, and who pays for what services. Based on all of these important factors, we selected the best real estate websites.
Aggregator Definition – Investopedia
What Is an Aggregator?
An aggregator is an entity that purchases mortgages from financial institutions and then securitizes them into mortgage-backed securities (MBSs). Aggregators can be the issuing banks of the mortgages or subsidiaries within the financial institutions themselves. They can also be brokers, dealers, correspondents, or another type of financial corporation. Aggregators earn a profit by purchasing individual mortgages at lower prices and then selling the pooled MBS at a higher price.
An aggregator is any entity that purchases mortgages from financial institutions and then securitizes them into mortgage-backed securities (MBSs) for suing banks, subsidiaries within the financial institution, brokers, dealers, and correspondents can all be gregators function as service providers that remove the work for issuers in creating a mortgage-backed mortgage originators become aggregators in the securitization process, they create special purpose vehicles (SPVs) to facilitate the transaction.
Understanding an Aggregator
Aggregators are essentially service providers who eliminate some of the effort issuers need to go through in creating a mortgage-backed security. Depending on what the end customer is looking for, aggregators can seek out and purchase a defined type of mortgage from a diverse set of lenders and originators. By expanding the search across a variety of mortgage originators, including regional banks and specialty mortgage companies, it is possible to create tailored mortgage-backed securities that can’t easily be sourced from a single mortgage originator.
Secondary Mortgage Market
Aggregators are better understood as a phase of the securitization process rather than a distinct entity in the secondary mortgage market. When an originator, like a bank, issues a mortgage, they want to move it off the books to free up capital so that they can issue more loans. Selling a single mortgage directly to an investor is tricky because a single mortgage faces a lot of difficult-to-quantify risks based on the individual buying a property. Instead, the aggregator buys up a collection of loans where overall performance is easier to predict and then sells that pool to investors in tranches. So there is a pooling/aggregation phase that takes place before the MBS can be sliced up and sold.
When Aggregators Are Also Originators
Mortgage originators often become aggregators, as securitizing a pool of mortgages can be seen as a natural extension of their business. When the originator acts as an aggregator, they usually create a special purpose vehicle (SPV) as a walled-off subsidiary for pooling and selling loans. This removes some liability and frees up the originator’s aggregator arm to purchase loans from other institutions as well as from the parent entity, as is sometimes necessary for the creation of a tailored MBS.
In theory, the originator-owned aggregators operate the same as third-party aggregators even though they are dealing with a majority of the mortgages from a single customer, which is also the owner. In practice, there could be situations that would not exist with a third party. For example, the aggregator could be subtly encouraged to not seek as steep a discount on secondary market mortgages to help the parent company’s balance sheet, shifting any overall loss to the aggregator. Of course, the MBS market leading up to the mortgage meltdown had more significant issues than the possibility of an aggregator and originator colluding.
MLS Aggregator Engine – Listings From Multiple Markets In One Place
Listings from multiple markets in one place
In the US, there are 800+ Multiple Listing Services (MLS). MLS systems set their own rules for membership, data access, and data sharing information.
Because each MLS has different data standards, integrating multiple MLSs into a website or mobile app(s) is a painful process.
As businesses grow into new markets, it gets increasingly difficult to manage data from multiple MLSs.
Real Estate IDX was widely popular but has more cons than pros in the current real estate tech space.
SaaS-based RETS platforms are available. Most platforms claim to offer plans with no long-term contracts, no hidden fees. Over a long period, these platforms prove too costly.
Here is an example:
Assume a typical platform cost of $100 /month/MLS. The annual cost for 5 MLS integration comes to $100 x 5 x 12 = $ 6, 000.
MLS Aggregator engine can help you reduce the cost and increase the usefulness of your data feeds by bringing multiple MLS into your system. Your custom application can then consume this data as per your requirement.
