Buying or selling in Northern New Jersey
Make your move with the numbers on your side.
I'm Sergey Antonov, a Coldwell Banker agent in Northern New Jersey. I track what homes actually sell for, town by town, and I built free tools so you can decide on facts instead of headlines, wherever you're buying or selling.
See where your home would rank before you pick a price.
Buyers compare your home to three or four others in your price range. I'll show you which ones, where you'd land among them, and how fast your local market is moving right now.

See how hard buyers are competing in each town.
Every town is its own market. Here's what buyers have paid compared with asking price so far this year in the 13 towns I track most closely. Looking somewhere else? I can pull the same numbers for any town in North Jersey.

The dark line is the asking price. Past it, buyers are competing; short of it, they're negotiating. Tap a town for its full report.
About Sergey
Data first. Pressure last.
I'm Sergey Antonov, a real estate agent with the Jill Biggs Group at Coldwell Banker in Hoboken, working with buyers and sellers across Northern New Jersey, with a special focus on Upper Bergen County.
For sellers, I price and position homes against the handful of listings buyers actually compare them to, and I manage the parts of a sale where deals quietly fall apart: inspection, appraisal, and the weeks before closing. For buyers, I start with what a house will really cost you each month, not the biggest number a lender will approve.
I wrote a short book on the seller side of this, The Competitive Band, and a free guide for buyers, The Homebuyer Money Leak Guide. Both are free on this site.
