London is the exception, prices there have been driven up by an influx of foreign investors, who have bought not only properties costing millions but also flats that would otherwise have been bought by local people to live in, and prices for property in and immediately around London has gone up in line with the domino effect of wealthy local unable to compete with foreign investors and moving to the next suburb out.
Further out prices are more reasonable. The average house price in the UK, including all houses and London is £235,000, which means in many areas there are a lot of properties far cheaper than that. In York where DS lives there are plenty of starter flats under £100,000, 3 bedroomed houses are priced from £150,000.
Similar properties in North Herts, where DD lives within an easy commute to Cambridge are £150,000 and £225,000. In South Oxfordshire, where I live, surrounded by science parks and an easy commute to Oxford, Newbury and Reading the figures are £150,000 and £250,000
All these areas are high employment, high salary areas, and many first time buyers seem quite able to play in excess of £300,000 for a first home.
As for saving for a depositt. It has never been easy. In 1968 we needed to save £1,000 to cover deposit and costs. Roughly equivalent to one year of my then gross salary, considerably longer if you only looked at my take-home pay.
My parents delayed their marriage several years until my DF was earning £4.50 a week and they could afford a mortgage to buy a home.
House buying has never been easy. It is just a shock to young people, many of whom have had very easy lives, to suddenly find that something they take for granted requires sacrifice and hard work to obtain.
