A new study has revealed that St Davids is the least affordable city in the UK in which to own a home. 

The study, from data collection experts SmartSurvey, assessed the disposable incomes of two average-earning homeowners living and working in every UK city after paying household bills and mortgages. 

St Davids was the least affordable of any city in the UK, with median house prices of £450,000 and average monthly earnings of £1,921.

After mortgages and basic bills, which are estimated at £385 per month, a household with two average incomes would have £864 left for groceries, clothing, transport, and any other necessities.  

SmartSurvey estimated that a single average earner could not realistically become the sole homeowner of a property in St Davids as their income covers only two-thirds of the mortgage rate alone.

On average in the UK, the median price for a city home is £260,000, with city residents generally earning £2,154 a month. 

Gas, electricity, water and council tax bills amount to an average £348 every month, while mortgage rates are estimated at £1,520, meaning that the average two-earner household would have £2,440 in disposable income for the month.  

All of the five least affordable UK cities, including St Davids, are cathedral cities, with higher property prices and bills, and lower incomes. 

Mo Naser, CEO of SmartSurvey, commented: “If you really have your heart set on living in a quaint cathedral city, you would most likely need to earn your paychecks elsewhere and commute for a quarter of a century to pay off your mortgage. Otherwise, you are looking at 25 years with hardly any disposable income left.”
