Mehdi Mozadeh moved into his Park Avenue house with his wife and two young children three months ago.
The flooding has damaged his property, furniture and even his children’s school uniforms.
“I don’t know what I should do… [I have] no idea where I’m going to stay,” he said.
On Saturday, an emergency payment scheme was activated by Communities Minister Gordon Lyons.
It means householders who have suffered “severe inconvenience” from flooding can claim a £1,000 payment through their local council.
But Mr Mozadeh said that he has not received any help or support since Saturday’s flooding.
“This is my life and [this is] so hard for me.”
Damage was also reported in County Tyrone, with up to 10 homes having been flooded in Coalisland on Saturday.
