Pedro Quezada, 44, said he would pay his neighbors' rent for one or two months in his New Jersey town of Passaic.
Quezada, a bodega owner, moved to Passaic from the Dominican Republic 26 years ago.
Richard Delgado, 45, a neighbor of his, said he was thankful for Quezada.

Another neighbor said the lottery couldn't have been won by a more deserving couple, as he recalled that he and his wife Ines Sanchez worked so hard that they rarely ever saw them.
"He's somebody who needs it, not like the people who had millions already and won it," Cheech Rivera, 57, said.
"They struggled. They are always constantly working. They don't really have time to get together with us."
Quezada has paid the $29,000 he owed in child support and will no longer be working at the bodega he owns in Passaic. He is also insisting that his 23-year-old son quit the job as well.

"With all those millions, would you allow your children to work in a store like that?" he said.
He also joked that he would continue to play the lottery, though he has already won a large sum.
Though he is going to pay his neighbors' rent for a month, he is going to be careful about the money.
"You have to be careful, some people aren't good people," he said. "My life has to change because it's so much money, but it will not change my heart."
He did not say where he was going to go next, but he said he might buy a house in New Jersey, the Dominican Republic or Mexico.
Quezada said his winnings did not sink in until he saw himself on television.
"The store is located on the way to my deli store so when I saw the commotion outside I figured maybe the winning ticket was purchased there, so that's why I stopped," he said. "When the gentleman checked, he said, 'congratulations!'
After taxes, he took home $152 million in a lump sum.
"I can't believe it. I'm overwhelmed. I was praying so much for this," he said.
