Who is Andrew Diaz?

Andrew Diaz is a real estate Sales Associate with Costanza Realtors, serving Hudson County, New Jersey. My core markets are Bayonne, Jersey City, and Hoboken, and I work the rest of the county too. Whether you’re buying your first home, selling a property, hunting for a rental, or leasing out a unit you own, I’m on the same side of the table as you the whole way through.

What sets the work apart is the desk itself. Most agents check the MLS when a client asks. I do the opposite: I keep the entire Hudson County MLS in front of me at all times, and every active listing is published right here on stanzax.com. That means no waiting for a callback to find out whether a place is still available, what it should really sell for, or how it compares to everything else on the block.

What I help with

Buy a home → Get matched to the right listings the moment they hit the market, with an honest read on price. Sell a home → A free, no-obligation valuation built on real recent sales — then a plan to get top dollar. Find a rental → Every active rental in Hudson County, filtered to exactly what you need — fast. Rent out your unit → Price it right, market it widely, and screen for a qualified tenant — handled.

How I work

Straight answer first, conversation second. Tell me what you’re trying to do and I’ll give you the real picture — the comparable sales, the days on market, the catch nobody mentioned — before I ever ask you to commit to anything. No spam, no pressure, no obligation. If the numbers say wait, I’ll tell you to wait. That’s how you build a client for life instead of a one-time deal.
