How do online mortgage brokers work?

Online mortgage brokers – sometimes referred to as 'robo advisers' – allow you to carry out most of the mortgage comparison and application process online, without speaking to a mortgage broker in an office or over the phone. 

This might mean submitting details about your mortgage search to a chatbot, filling in an online form, or selecting options in an app.

Some of these services claim that you can find and apply for a mortgage in just 15 minutes, at the touch of a button – a process that can potentially be much faster than speaking to a broker or carrying out extensive mortgage searches yourself.

However, there will be still be paperwork to go through, and human mortgage brokers will still be used at some point in the process in order to make sure your application is correct and legally binding.

Can robo advisers prevent over-borrowing?

While tighter regulations were introduced in 2014 to protect homebuyers from overborrowing, nothing is foolproof. 

Traditionally, affordability assessments have been used to see how much you spend – not just on bills or rent, but gym memberships, eating out, holidays and sometimes even childcare – as well as how much you earn.

A human mortgage adviser will go through your bank statement and take all of your outgoings into account when recommending a mortgage. 

Arguably, an algorithm is less able to account for these nuances and make judgements about whether you can really afford to borrow the maximum amount available to you for a mortgage.

Online brokers do have systems in place, however. For example, MortgageGym has paired its service with Experian, meaning existing credit and borrowing commitments are automatically taken into account (and with only a soft credit check). 

There are also future plans to launch integrated income and expenditure assessments by using open banking technology to gain insight into customers’ current accounts.

The other online brokers have human mortgage advisers on hand who will look at credit reports, loan statements and other records to assess customers’ borrowing capacity, and check to see if the AI-generated mortgage options are suitable.

Pros and cons of using an online mortgage broker

Searching and applying for a mortgage using a chatbot or app can be a convenient option for those who don’t have the time, knowledge or confidence to do it themselves.

Pros of online mortgage brokers

  • Flexibility You don’t need a face-to-face meeting or phone call with a mortgage broker, meaning you don’t need to restrict yourself to office hours – you can find a deal at any time of day, from wherever you are.
  • Less paperwork Papers are replaced with online forms, which can be filled out at your convenience. What’s more, some services will help you with these forms, too, meaning there's less chance of human error. You’ll be asked to provide documents to verify your identity and finances, but often these can just be scanned and sent over. 
  • Speed The use of technology and algorithms means your mortgage options can be found more quickly than in a manual human search.
  • Fees In most cases, you won’t need to pay for the advice you receive from robo mortgage services.

Cons of online mortgage brokers

  • Less opportunity for human judgement Fully automated services can sometimes overlook factors of more complicated circumstances – for instance, the cheapest deals aren’t always the most suitable options.
  • Less help in the early stages A good mortgage broker will give you advice on saving and schemes before you’re ready to apply for a mortgage. Some online services offer calculators to give you an idea of how much you’ll be able to borrow, but in most cases this can't be classed as actual advice, and isn’t tailored to your situation.

Should I use an online mortgage broker?

This really depends on your circumstances and the kind of service you want.

For straightforward cases, particularly if you’re looking to remortgage, using a robo adviser can be a very quick and easy option – especially if you work unsociable hours and would struggle to find time to talk to a traditional broker.

If your circumstances are more complicated, however, you might benefit from having tailored support from an expert adviser earlier on in the process.

Whether you’re thinking about using an online broker or a human one, you should always check to see whether they’re FCA-registered – you can search for them on the FCA’s database.
