Homeowners are so determined to acquire their dream family home that they remain undeterred by price rises of up to £80,000 for an extra bedroom, a new report claims.

Statistics from the Yorkshire Bank's quarterly Housebuyers Report reveal that the cost of an extra bedroom on a property currently averages £34,000 - but it also shows that one more room can add as much as £80,000 on the price of a property in areas such as York - and as little as £7,000 in Manchester.

"Our research shows people are not being put off by the high price of an extra bedroom, but we are seeing homebuyers become more prudent in their purchases to ensure they can afford their increased repayments," Gary Lumby, Yorkshire Bank's head of retail, commented.

The study revealed that only 14 per cent of homeowners would be concerned if their mortgage payments increased by around £40 to £50 a month.

"If people are thinking of starting or growing their family, it could mean a drop to one income, so considering a discounted rate mortgage or one that allows payment holidays could be a sensible option," Mr Lumby continued.

"It's crucial not to over-stretch yourself financially and the step up to a bigger home can be a big jump in price depending on where you live."
