One-, two-, and three-family homes run from $550,000 to $1 million. Co-ops can be more affordable than renting, especially if you're willing to live in a high-rise around Hall Street or in the Clinton Hill Cooperatives. Studio, $89,000 to $125,000; one-bedroom, $100,000 to $280,000; two-bedroom, $180,000 to $350,000. Buyers are most attracted to Clinton Hill's stunning mansions with rooms as wide as 30 feet. A lot of area owners are Pratt professors or former students who bought years ago for next to nothing.
