347 21st Street, Brooklyn

    A long-held South Slope two-family house where the surrounding street traffic carries the story.

    A two-family Brooklyn townhouse built in 1899 that has stayed under the same family umbrella since 1994. Ownership transferred title to an LLC in 2009 with Katerina Moutzouroulias named as head officer. Two things to know:

    Decades of single-family ownership stability. The house changed hands in 1994 and moved into a family LLC in 2009. That signals a long-hold owner rather than an investor group flipping between buyers, keeping the focus squarely on building maintenance and mechanical upkeep.

    Curb space turns over quickly within three blocks. 99 illegal parking calls were logged within three blocks over the last year, primarily blocked hydrants, crosswalks, and posted sign violations. It points to active curb turnover and delivery friction on the surrounding streets.
