1. Price it right the first time
The biggest mistake I see sellers make — in Hoboken, in Tenafly, on the Upper West Side — is pricing on hope instead of data. First two weeks on market is when you get the most showings, the most buzz, and the most serious buyers. Over-price, and you burn that window watching your listing go stale. Price it sharp, and you'll often see multiple offers in Hudson County; in Manhattan you'll see interest from the brokers who matter.
I build every pricing strategy off recent closed comps (not the wishful asking prices you see on Zillow), current active inventory you'll be competing against, and what's in contract but not yet closed — because that's where the market actually is today.
