The Agent Behind the Rankings
Costanza Genoese Zerbi
Founder · Lead Agent · Long Beach, CA
Costanza didn't just build a real estate career in Long Beach — she built it here, in the city she's called home for three decades. She knows every neighborhood, every micro-market, every nuance that separates a Belmont Shore bungalow sale from a Naples waterfront close. That depth of local knowledge isn't something you can import from another market.
In 12 years of practice, she has personally closed over 600 homes and been ranked the #1 listing agent in Long Beach by RealTrends for five consecutive years — placing her among the top 45 agents in California and the top 0.01% of all Realtors in the United States. Her MBA from UCLA Anderson School of Management means your home is priced with financial rigor, not guesswork.
What sets Costanza apart most isn't the rankings. It's that she never hands you off. Every valuation, every marketing decision, every negotiation — that's Costanza.

What Makes the Difference
Why Sellers Choose Costanza Over Every Other Option in Long Beach
Most agents offer a listing. Costanza offers a strategy built on 12 years of closing deals in this specific city, an MBA-caliber understanding of pricing, and a white-glove commitment to doing the work herself.
30 Years in Long Beach. 12 Years Selling It.
Costanza knows which streets in Belmont Shore command a premium, which Naples lots have appreciation potential, and what buyers are searching for right now in Alamitos Heights. You can't learn that from a comp sheet — you learn it from living here.
MBA-Backed Pricing — Not Guesswork
Costanza prices your home the way a financial analyst prices an asset. She models absorption rates, days-on-market trends, micro-neighborhood dynamics, and buyer psychology. In a 2025–2026 market where a $50K mispricing costs you weeks of leverage, this precision is everything.
Digital Marketing That Actually Finds Buyers
Through Ylopo's AI-driven platform, your home reaches qualified buyers across Google, Facebook, Instagram, and every major real estate portal — with retargeting that follows interested buyers until they act. Your listing won't just be on the MLS. It will be everywhere.
You Work With Costanza. Not Her Assistant.
Large volume teams assign you a listing coordinator, a showing agent, a transaction manager — a different person for every step. When you hire Costanza, Costanza is there at valuation, at preparation, at every negotiation, and at closing. No handoffs. No dropped balls.
Verified #1 — Not Self-Reported
Costanza has been ranked the #1 listing agent in Long Beach by RealTrends for five consecutive years. These rankings are based on independently verified closed transaction volume — not marketing claims, not team totals, not inflated numbers.
Seamless Compliance & Expert Guidance
From FINCEN RRER reporting on all-cash transactions to 2026 California disclosure requirements (AB 455), the regulatory landscape has never been more complex. Costanza handles every detail so nothing derails your close at the worst possible moment.
The Standard She Holds Herself To
No Hand-Offs. No Assembly Line. Costanza at Every Stage.
Large teams are built for volume. They hand your listing off piece by piece — intake coordinator, listing manager, showing assistant, closing team. The agent you hired may be largely absent by the time you're in escrow.
Costanza built her practice on a different model. She is personally involved from the first conversation to the final signature.
- 01Pricing & ValuationCostanza runs the financial analysis herself — MBA-level modeling applied to your specific home and micro-neighborhood.
- 02Property PreparationShe walks your home personally and advises on exactly what to fix, stage, or skip — so you spend money only where it creates value.
- 03Marketing ExecutionEvery piece of content — photography, ad copy, targeting — is reviewed and approved by Costanza before it goes live.
- 04NegotiationCostanza is at the table personally, with the full context of every buyer interaction, every showing, every piece of feedback.
- 05Escrow Through CloseShe stays on every contingency, deadline, and compliance detail herself. Nothing falls through the cracks at the worst possible moment.
Pricing Intelligence That Changes Outcomes
The Difference Between Data and Insight
Most agents pull a few comps and call it a valuation. Costanza's MBA from UCLA Anderson means she approaches your home's price as a financial asset — modeling absorption rate shifts, days-on-market by micro-neighborhood, and the pricing psychology of competing inventory.
In a Long Beach market where buyers are sophisticated and data-fed, a precise, defensible price is the difference between 10 days and multiple offers — and 60 days with price reductions.
This Is Her City
Long Beach Isn't Just Where She Works.
It's Been Home for 30 Years.
Costanza has watched Long Beach neighborhoods evolve, seen which streets appreciate and why, and built relationships across every community from Belmont Shore to Signal Hill. That three-decade perspective is something no agent from outside this market can replicate — and it shows in every transaction.
I interviewed four agents before calling Costanza. Her pricing analysis was in a completely different league — she walked me through the market the way a financial advisor walks you through a portfolio. We listed, got multiple offers in 6 days, and closed over asking. I would never use anyone else.
