The gap between average income and average house prices has changed between 1985 and 2015 from twice an average salary to up to six times average income. Median house prices in London the median house now cost up to 12 times the median London salary. In 1995, 19,000 and the median house price was £83,000, 4.4 times median income. By 2012-13, the median income in London had increased to £24,600 and the median London house price had increased to £300,000, 12.2 times median income [7]

In 1995 the Bank Base Rate was 6%, in March 2009 it stood at 0.5% until August 2016 when it was further reduced to 0.25%.[8]

An analysis by the LSE and the Dutch Bureau for Economic Policy Analysis found that house prices in England would have been 35% cheaper without regulatory constraints.[9] A report by the Adam Smith Institute found that by using 4% of London's green belt, one million homes could be built within 10 minutes walk of a railway station.[10]

The Economist has criticised green belt policy, saying that unless more houses are built through reforming planning laws and releasing green belt land, then housing space will need to be rationed out. It noted that if general inflation had risen as fast as housing prices had since 1971, a chicken would cost £51; and that Britain is "building less homes today than at any point since the 1920s".[11] According to the independent Institute of Economic Affairs, there is "overwhelming empirical evidence that planning restrictions have a substantial impact on housing costs" and are the main reason why housing was two and a half times more expensive in 2011 than it was in 1975.[12]

The Campaign to Protect Rural England argued that "Green Belt land is important for our wider environment, providing us with the trees and the undeveloped land which reduce the effect of the heat generated by big cities. Instead of reducing this green space, we should be using it to its best effect. We know from our research that three quarters (79%) of the population would like to see more trees planted and more food grown in the areas around towns and cities."[13]

Value of land and buildings in the UK from 1995 to 2016 (trillions).[14]

Property companies state that land values follow house prices and that a developer assesses what new build house price is achievable in any particular location with reference to prices and sales rates in the second hand market and on nearby comparable new build sites. At a basic level (assuming no affordable housing, S106 or CIL), they then multiply that new build house price by the number of homes to be built on the land and to arrive at the gross development value (GDV) of the site. The underlying value of the land is then the GDV less the cost of development and less an allowance for profit.[15]

According to a study by Knoll, Schularick and Steger, up to 80% of the rise in houses prices between 1950 and 2012 can be attributed to the increasing price of land.[16][17] This is for two reasons. Firstly, before 1950 improving transport meant that more and more land was economically usable, but this effect subsided after 1950. Secondly, zoning restrictions did not allow the "utilisation of additional land".[16]

Stamp Duty Land Tax is payable by the buyer of a property as a percentage of the purchase price.

From December 2014, Stamp Duty was changed to a graduated system which eliminates the jumps in stamp duty at the threshold values. For instance a property of £600,000 under the old system would pay 4% tax of the whole asking price i.e. £24,000. Under the new system no tax is paid on the first £125,000, the next £125-250,000 is charged at 2% i.e. £2500 plus the portion (£350,000) in the £250,000-£925,000 tax band at 5% i.e. £17,500. This gives a total tax of £20,000. This change was said to be beneficial to 98% of property purchases[18] but caused a collapse in sales at the upper end of the market.[19][20]

In 2011, Which? magazine found the national average estate agents fees to be 1.8%.[21]

There are four main types of survey: a valuation survey, a condition report, a homebuyer report and a full structural survey.[22]

Conveyancing fees vary according to the value of the property and the service provided.[23]

In April 2013, The Daily Telegraph reported that research by Moneyfacts showed the average mortgage arrangement fee to be £1522.[24]

The Joseph Rowntree Foundation has suggested replacing the current Council tax system based on bands of house prices with a system which would mean the tax was more closely related to property prices. This would increase taxes on the highest priced properties and decrease them for the lowest. They claim it would also have the effect of reducing house price volatility.[25]

Land value tax is suggested by some as a replacement for council tax; it would be based entirely on land (i.e. location) value and not on the value of buildings built on a piece of land or improvements made.[26][27] [28]

In 2015, the Bow Group, a conservative think-tank, produced a report suggesting a reduction in international investment demand of property. The report proposed limiting foreign residents to the purchase of single new-build properties, with penalties if sold within five years.[29] In 2016, London mayor Sadiq Khan launched an inquiry into housing costs in the city, also highlighting the impact of foreign investment.[30]

The government set up a £60 million fund to help councils deal with high levels of second home ownership.[31] In 2016, a referendum in St Ives, Cornwall found 83.2% of voters in favour of new housing projects being reserved for full-time residents, as many tourists frequent the area and Cornwall is popular for second home and vacation property ownership.[32]

From April 2016, a Stamp Duty surcharge of three per cent of the purchase price was required for those buying to let. From April 2017, buy-to-let mortgage interest payments will have higher rates of income tax relief phased out by the government.[33] Although, companies would not be affected by the new rules.[34]
