Mortgage Calculator - Guide for Expats

Many clients come to Revolution having used an online calculator, and received misleading results.

While expat mortgage calculators can be useful, they are only ever indicative. It is never wise to make an application based on an estimate, as this can result in being rejected for lending, and negatively impacting your credit score.

Let's explain where mortgage calculators for expats can be useful, and how to use them to your advantage.

How Do Mortgage Calculators for Expats Work?

Mortgage calculators need a few critical pieces of information, such as:

  • Your income
  • How much deposit you have
  • How long you want the mortgage to run for
  • A rough idea of the mortgage rates payable

Most information is available online, but it's worth remembering that the rate you are likely to be offered might vary significantly, as it all depends on your circumstances.

What Do I Need to Know to Use an Expat Mortgage Calculator?

Mortgage providers all have a set of criteria they need applications to comply with before they can be approved. Mortgage calculators cannot consider every aspect of your application, but they usually look at:

  • How old you are.
  • Your employment status and income.
  • Your credit rating or history.
  • What type of property you want to buy.

These criteria are not unique to expat mortgages, but other factors will have a more significant impact on your chances of approval, and what rates you are offered:

  • Your Status as a Homeowner - If you already have a UK property, you are in a better position. Lenders will often accept a second charge against an existing home as a way to reduce the deposit required on an expat mortgage to around 25%.

Should you not be a homeowner, you're likely to need a deposit around 35%.

  • How Currencies are Likely to Change - Lenders will need to know where you live, since if the currency is volatile, it might dramatically change your ability to keep up with your mortgage payments.
  • Should I Get a BTL or a Residential Expat Mortgage? - If you need a residential expat mortgage for a home to live in, you will be offered different rates and terms than if you want a BTL expat mortgage to invest in a buy to let property.
  • Is it Better to Take Out a Purchase Mortgage, or a Remortgage? - Again, this will change how much you can borrow, what products are suitable, and what interest rates a lender might offer. Generally, a remortgage is more straightforward and easier to qualify for then a purchase mortgage as an expat.

What are the Benefits of Using an Expat Mortgage Broker?

A broker is the next step once you have used an expat mortgage calculator to get a rough idea about what you can borrow, and how much the repayments might be.

There are multiple reasons a broker offers a more tailored service than a generic mortgage calculator:

  • Recommendations consider all lenders on the market, rather than offering a small number of brokers tied in with the calculator service.
  • Revolution considers your circumstances and will recommend the lending product we think is best suited, and most cost-effective - even if that isn't a mortgage.
  • The team are highly experienced in expat mortgages and can provide invaluable advice and help with negotiating rates.
