Can I bring a fraud lawsuit against a Real Estate Broker after 4 years?

In 2012, I approached a real estate broker because i was looking for a commercial space for rent. After I met the real estate broker, he told me he need a deposit in irder to hold a space if I get my loan to go ahead. I gave him the $500 deposit. When I wasn't approved for the loan, I told the broker and was told his partner, who I never met or heard about, would sent me a check. I never received one. During that time, I became ill and wasn't able to go ahead with a lawsuit. I also suffered a stroke that kept me from moving ahead with the law suit. It's been 4 years already and I'm wondering if it's too late to file a lawsuit in civil court?
