Aberdeen is the cheapest city for starter homes with an average asking price of £102,601, according to Rightmove.
Analysis by the website does not take into account regional differences in income, but looks at the average asking prices of homes with two bedrooms or less, which are often bought by first-time buyers.
It showed that the average mortgage payment for first-time buyers in Aberdeen would be £406 per month, assuming a 20% deposit and a term of 35 years.
Bradford is the second cheapest city as a starter, with an average asking price of £107,929, and Sunderland is the third cheapest, at £111,263.
This compares with an average asking price of £501,934 and monthly mortgage costs of £1,862 for a similar sized home in London, the most expensive location for first-time buyers.
Outside the capital, St Albans is the most expensive city, with an average asking price for first-time buyers of £391,964 and mortgage costs of £1,454.
This is followed by Cambridge and Winchester.
For renters, Carlisle is the cheapest city with the average advertised rent for a two-bedroom property or smaller now £607 per month.
This compares to £2,264 per month in London for a home of the same size.
Oxford is the second most expensive city for renters outside the capital, with average rents of £1,561 per month for properties with two bedrooms or less.
Paying a mortgage is cheaper than renting in all of Britain’s major cities, Rightmove found.
The cost of renting a home with two bedrooms or smaller has risen 39% over the past five years, compared to a 19% increase in the cost of buying a home with two bedrooms or smaller.
Rightmove property expert Tim Bannister said: “These latest figures highlight why so many people remain determined to get on the ladder, as the rising cost of renting has meant that buying has remained attractive, even with higher mortgage rates.
“Longer mortgage terms are becoming increasingly common as a way to improve overall affordability and reduce monthly payments, although first-time mortgage buyers should be aware of what they are paying in interest compared to their actual mortgage.
“Without improvements to the supply of good quality, affordable rental housing in Britain, home ownership is likely to remain the end goal for those who can get their deposit together and borrow what they need from a mortgage provider. .”
