Here’s a depressing statistic: saving a deposit for a home in the exclusive Kensington postcode where Harry and Meghan will live would take the average newlyweds 133 years, according to research from online mortgage broker Trussle.

The royal couple will live in Nottingham Cottage, a two-bed home on the grounds of Kensington Palace, in London’s W8 postcode - where the average detached house costs a staggering £11.53million (in comparison, the average cost of a detached house elsewhere in the UK is £365,697). A couple earning the average UK salary of £44,297 would need to save a third of their take-home pay every year, for 133 years, to scrape together a deposit of 17% of the property’s value (£1.96million).

Of course, this isn’t the financial scenario that most newlyweds find themselves in. However, there are certain things that couples need to consider when managing their finances and saving as a pair, rather than individually.

Here, Ishaan Malhi, CEO and founder of Trussle, shares his four golden rules of money management for any newly married couple.
