Sales of residential property

Sold a residential property to an individual. The buyer paid for the property in full over a period of 5 months. A realtor was not used. Cash was paid so there is no involvement by a mortgage company. I need to get the title/deed transferred to the buyers name. He states he cannot afford the cost of getting deed transferred. Since the deed is not transferred, as owner I am still responsible for utilities, taxes, insurance, etc. How can I get the deed transferred into the buyers name? The residential sale is in Easton, PA. Northampton County.
