After an abandoned effort to turn it into a public school, the former St. Joseph's Hospital in South Providence will be put up for sale by real estate developer Joseph R. Paolino Jr., who hopes it will be turned into badly-needed housing. The listing is set to go live tonight through real estate company Cushman & Wakefield, which will conduct an auction. There is no asking price, said Paolino, who is seeking proposals. Paolino thinks a mixed-use development with housing would be the best use of the property, though he's open to other proposals. He originally sought to develop the property himself, but was unable to secure COVID relief funds earlier this year from quasi-public agency R.I. Housing, which administers affordable housing subsidies. He ultimately decided the project needed a developer with more experience in subsidized housing.
