The Bank of England will make lenders be slightly more careful in testing whether borrowers could afford a rise in interest rates.
Some will argue new figures reinforce the Bank of England governor's view - that Help to Buy is small-scale and essentially benign.
The UK's Property Ombudsman is warning about a growing number of estate agents charging not just sellers - but also those purchasing homes.
- Stamp duty is imposed on the total value of the property, so someone buying a home for between £250,000 and £500,000 pays between £7,500 and £15,000.
- Sales of houses up to the value of £125,000 are free of stamp duty.
- Property up to £250,000 will cost the buyer 1% of that price in stamp duty.
- Would-be homeowners buying property in the range of £250,000 to £500,000 will pay stamp duty to the tune of 3% of the houses' value.
- Homes valued at over £500,000 to £1 million will force the buyer to pay stamp duty of 4%.
- Property in the £1 million to £2 million bracket has a 5% stamp duty charge.
- Buyers purchasing property over the £2 million mark will have to pay 7%.
The average homeowner will pay almost £12,000 in stamp duty over the course of a lifetime of climbing the UK property ladder, research from a High Street bank found.
Lloyds Bank said the average homeowner faces paying £11,782 in stamp duty, on top of the cost of buying a house.
As people typically spend just under eight years living in a property, the research assumed that a home owner had bought their first property in 1998, their second in 2006 and their third in 2014.
The rigid "slab" structure of stamp duty has been strongly criticised, particularly as surging house prices have pushed more homes into higher tax brackets.
A major lettings network has reported private sector rents have been getting cheaper in real terms throughout the last year as stability returns to the market.
A 0.6% month-on month increase in average rents took the typical amount paid by tenants across England and Wales to £745 a month in May, accelerating from no monthly change in April, according to LSL Property Sevices, which owns national chains Your Move and Reeds Rains.
But despite the pick-up in costs, private sector rents were 1.1% or £8 a month higher than they were a year ago, which is below the Consumer Prices Index (CPI) rate of inflation of 1.5% in May.
Chancellor George Osborne says measures unveiled today will help prevent "future risks" to the housing market by letting the Bank of England intervene on the size of mortgages homebuyers can obtain.
Mr Osborne also said action to build more homes would help more people get on the housing ladder.
The Business Secretary has said that banks must be put under more pressure not to "throw petrol on the fire" of the house price boom by lending people mortgages worth up to five times their salaries.
Vince Cable said he had been "appalled" to discover the size of loans being agreed by some lenders and urged the Bank of England to use its powers to intervene.
He told BBC Radio 4's Today: "It is crucially important that the banks don't throw petrol on the fire.
"Most of us who have been through various housing booms in the past have recognised that a kind of stable level is three or three-and-a-half times
"I was appalled when I discovered that banks were lending five times."
House prices rose by 8.7% annually in May to reach £184,464 on average and by 3.9% month-on-month, Halifax has reported.
European Commission calls for the UK to raise taxes on expensive homes, build more housing and "adjust" the Help to Buy scheme are "in line" with government policy, a Treasury spokesman has said.
"The European Commission continues to support the UK Government's strategy including its commitment to deficit reduction. The Commission's recommendations are in line with the Government's approach," the spokesman said.
Rural savers typically have around £1,500 more squirrelled away than their urban counterparts, a report has found.
People living in the countryside have £10,357 put aside for a rainy day on average, which is £1,537 more than people living in towns and cities who typically have £8,820 in their nest egg, according to Halifax's "savings barometer" of England and Wales.
The biggest gap between urban and rural savers was found in the West Midlands, where the balances of those living in the countryside were typically 31% or £2,431 higher than those in towns and cities.
Across the findings, rural savers typically have 44% of their gross annual earnings put away, compared with 34% for urban savers. The smallest average balances were found in the London boroughs of Newham and Hackney, at £5,173 and £5,241 respectively.
The group chief executive of Legal & General, Nigel Wilson, has told ITV News house prices will keep rising until the Government is bolder in tackling a "chronic shortage" of affordable new homes.
L&G boss says Help to Buy is "a huge emotional distraction from the main issue" a chronic shortage of new homes.
Nigel Wilson says society will never get the quantity of new homes it needs unless the government starts building affordable homes.
Nigel Wilson "the government should be building affordable homes. It worked in the 40s, 50s and 60s, it can work in 21st century as well"
The government's "restrictive" Help to Buy mortgage scheme should offer a wider variety of mortgages to make it more attractive to those eligible, a mortgage broker has told ITV News.
Jonathan Harris of Anderson Harris said: "The products on offer tend to be very short-term fixes and with the rates people are obviously paying a preview for the higher loan-to-values.
"It would be good to see a more competitive product range and more innovation from the lenders," he added.
