Lisburn Castlereagh ratepayers face twice the tax hike of their Belfast neighbours after council struck its highest rate increase in six years.
The domestic rate for the coming year has been set at 3.98 percent - up from 2.29 percent the previous year.
Rates will go up by £18.15 for properties valued at more than £150,000 - more than the £10 increase in 2019/20.
Business rates, however, will drop by 0.3 percent.
It's the biggest increase since Lisburn and Castlereagh councils were combined in 2015.
The district's previous rate increases have been among the lowest in Northern Ireland.
Meanwhile Belfast Council will increase rates by 1.99 percent, up from 1.98.
In a statement, Sinn Féin Councillor Ryan Carlin said the upcoming budget would prepare the council for the Brexit transition.
Big ticket projects include a revamp of historic Hillsborough, a pop up gym at Billy Neill Park and improved pitches.
He said: "The budget reflects the future sustainable development, growth and enhancement of the Lisburn Castlereagh area in the best interests of all."
The council has also pledged to cut costs. Cash saving projects include a kerbside recycling pilot for residents to better separate their waste, and increase the amount of recyclable material.
Cllr Carlin added: "During the next year it [council] will be implementing policies to reduce costs and introduce more sustainable practices ... which will contribute to our economic resilience."
