Overall, house prices in the UK ended 2017 2.6% higher, with London the weakest-performing region for the first time in 13 years, according to Nationwide Building Society.
The average UK price was £211,156 in December, marking a 0.6% month-on-month increase and contributing to the 2.6% annual uplift.
In the last quarter house prices actually fell by 0.1% in Northern Ireland.
The only cheaper region was the north east of England, which saw 0.2% annual growth to £124,535.
The annual rise was the slowest for any calendar year since 2012. It compares with a 4.5% annual increase in 2016.
For the first year since 2008 prices in northern England and the Midlands combined grew at a faster rate than in southern England, Nationwide said, with a 3.6% year-on-year increase compared with 1.6%.
In London prices were down 0.5% annually, taking the average to £470,922.
West Midlands was the strongest performer, with prices up by 5.2% for 2017, followed by the South West at 4.8%.
An increase of 3.3% was seen in Wales, and 2.6% in Scotland.
Robert Gardner, Nationwide's chief economist, said that 2017 "saw the beginnings of a shift" as rates of price growth in the South of England moderated towards those in the rest of the country.
He said: "London saw a particularly marked slowdown, with prices falling in annual terms for the first time in eight years, albeit by a modest 0.5%.
"London ended the year the weakest-performing region for the first time since 2004."
Mr Gardner said a 20% deposit in London now typically equates to more than £80,000, based on the average first-time buyer price.
This is around £30,000 higher than a decade ago.
In other regions, such as the Midlands and northern England, the deposit requirements for buyers are similar to 2007, he added.
