SALZBURG, Austria (Reuters) -Salzburg, the home of Mozart and "The Sound of Music", is not a place known for radical change.
The picturesque Austrian city, which draws tourists from around the world to its baroque palaces, Christmas market and summer festival of classical music and theatre, has had mayors from only two centrist parties since World War Two.
But now residents' growing exasperation at some of the highest housing costs in Austria could push them to elect a young Communist as mayor in a run-off election on Sunday.
"Our key issue, affordable housing, is not just an issue for people who have to live on a very low income but rather it has become an issue for the broad majority of people who live off their work and not their wealth," the Communist candidate, Kay-Michael Dankl, said in an interview at his party's offices.
If he wins Sunday's run-off against Social Democratic Deputy Mayor Bernhard Auinger, Salzburg will follow Austria's second city Graz in having a Communist mayor. The cities are rare successes for a party not even in national parliament.
"Many people who have lived in the city are moving back to the countryside or going back (elsewhere) because rents are extremely expensive," said 26-year-old social worker Michelle.
That Dankl's party, the Austrian Communist Party Plus (KPO Plus), came a close second in this month's city council election shows that protest votes need not be the preserve of the far-right Freedom Party (FPO), which leads in national polls but came fifth in Salzburg.
"Really this is an election based on personality," said political analyst Kathrin Stainer-Haemmerle of Carintha University of Applied Sciences.
Dankl, a 35-year-old historian and former leader of the Young Greens, grew his party's share of the vote to 23.1% this month from 3.7% in 2019.
Part of his success has been his personal appeal - he is a slick, calm speaker with bookish charm and an easy smile.
"He really is a very good and formidable communicator," political analyst Thomas Hofer said. "With his personality, his engaging nature, he is able to soften the harsh edges of the K in the party name."
He has also won over part of the public by keeping only 2,300 euros ($2,500) a month of his salary and donating the rest for one-off financial aid to constituents in need. Dankl hopes his dedication in addressing voters' concerns will outweigh rivals' calls not to vote for a Communist.
"I think most people in the city of Salzburg now know what we stand for," he said.
Rattling off figures and examples, he said that on average renters in his city spend half their household income on rent and associated costs like heating.
UNREALISTIC
Salzburg's housing crunch is particularly down to a relative shortage of social housing, according to a report two years ago by economic think tank Wifo.
Dankl wants to build 1,000 units of subsidised housing a year for 10 years, a goal his rival Auinger says is "completely unrealistic". He has pledged 1,500 units over five years.
But the plan resonates even with the wealthy.
"It's just impossible for young people to find an apartment. There just aren't any subsidised apartments and there should be a much greater supply," said Brigitte, 71, who rents out two apartments she owns.
Tourist accommodation is also a factor. Dankl wants to restrict the use of AirBnB (NASDAQ:ABNB) to a few weeks a year per apartment. Auinger, 50, says that will do little to fix the problem.
Both candidates support investigating how many apartments lie empty for much of the year and say a levy on empty apartments must be better enforced.
The suspicion is that many of these empty apartments belong to wealthy absentees, particularly from nearby Germany, who mainly visit during the summer festival.
"We live right over there in the old town and you can simply see how during the festival everywhere in the city the lights are on in the windows, and in winter it's dead," said Christian, 26, who is studying to become a teacher.
Just 821 votes separated Dankl and Auinger in the first round of voting and the two say they will work together whoever wins on Sunday.
