Parents in England face paying a premium of nearly £129,000 for a home near a top state school, according to analysis.
Properties near top state schools have an average house price of £415,844 - which is £128,615 or 45% higher than the average house price across the country at £287,229.
This average house price of £415,844 near a top state school equates to nearly 11 times average annual earnings, according to the study from Lloyds Bank.
House prices near top state schools were found to have surged at a faster rate than the national over the last five years - by £116,696 or 39% compared with £51,624 or 22% across England as a whole.
Lloyds Bank made the findings after comparing house prices in the postal districts of top schools with the county average, using government data.
It said property prices in the postal districts of top state schools in terms of GCSE results achieved in 2016 were on average £43,490 or 12% higher than in the wider county.
Homes near Beaconsfield High School in Buckinghamshire were found to command the biggest premium of £643,181 (158%) compared with the average house price in neighbouring areas.
Properties close to the Henrietta Barnett School in Barnet command the second highest premium in the study, of £367,632 or 59%.
But parents do not always need to pay a premium to live near a top school, the research found.
With an average price of £288,430, average properties close to the Reading School and Kendrick School, both in Reading, are £132,718 or 32% below the county average, which was the biggest discount for a house near a top performing state school within the survey.
These were followed by Aylesbury High School in Buckinghamshire with a discount of £112,674 and King Edward VI Handsworth School in Birmingham, where homes are typically £82,640 less expensive than in surrounding areas.
Andrew Mason, Lloyds Bank mortgage products director, said: "All parents want to ensure their children get a good education, so it's not surprising that homes in areas close to the top performing schools typically command a significant premium over the surrounding area and high demand has led to prices being out of reach for many buyers."
