RealtyUSA is set to buy a pair of offices from Elliott Realty Inc. as a means of growing its portfolio of New York assets.

The Amherst, N.Y.-based real estate broker has purchased Elliott’s offices in Watertown, N.Y. and Henderson, N.Y. for an undisclosed price. The Elliott Realty brokers and agents will now work under the RealtyUSA corporate name, but continue to serve those markets.
