Given the work that has gone in to see up a property database and a process for paying property tax over the last couple of years, I don't realistically think any major political party would now row back on the work done and get rid of the property tax.
FF have said they would suspend the tax for one year and SF said they would get rid but when it came to taxing the citizens to pay for the cost of running the country, I don't think either would do more than tinker around the edges.
