Most people spend more time researching a new TV than they do vetting their real estate agent. That’s a problem — because in New Jersey’s competitive market, the agent you choose directly impacts your sale price, how long your home sits on the market, and whether your deal actually makes it to the closing table.

Consider this: sellers who work with top-performing NJ agents net an average of 6% more than those who go with a generic referral. Buyers with well-connected agents find homes 25% faster and are far more likely to win in a multiple-offer situation. The difference between an average agent and a great one isn’t subtle — it’s measurable in dollars.

1 Hyperlocal Market Knowledge

Being licensed in New Jersey isn’t enough. You need an agent who knows your specific town and neighborhood — not just the state. The market in Hoboken is completely different from the market in Westfield, which is completely different from Montclair.

A great agent will know the average sale prices on your specific street, which blocks are in demand and why, what the school district boundaries look like and how they affect pricing, upcoming development or zoning changes that could impact value, and how long homes typically take to sell in your micro-market.

🔑 Ask them: “How many homes have you sold in my town in the last 12 months?” If the answer is less than 5, keep looking.

2 Proven Track Record with Real Numbers

Promises are easy. Data isn’t. Any agent can say they’re “the best” — but top agents can prove it with their transaction history, client reviews, and measurable results.

Look for total number of transactions in the last year (not career totals from 20 years ago), average list-to-sale price ratio (for sellers, this shows how accurately they price homes), average days on market compared to the local average, and verified reviews on Google, Zillow, and Realtor.com — not just testimonials on their own website.

🔑 Ask them: “What’s your average list-to-sale price ratio this year?” Top agents should be at or above 100%.

3 Communication Style That Matches Yours

This is where most agent relationships break down. You’ll be working closely with this person for weeks or months — if their communication style doesn’t match yours, you’ll be frustrated regardless of how talented they are.

Pay attention to how quickly they respond to your initial inquiry (if it takes 48 hours to return your first call, imagine what happens mid-negotiation), whether they communicate via your preferred channel — phone, text, email, or a mix, and whether they give you honest, direct answers or vague, salesy responses.

🔑 Test this early: Text or email them a question before you commit. The speed and quality of their response tells you everything.

4 Marketing Plan (for Sellers)

If you’re selling, your agent’s marketing plan is directly responsible for how many buyers see your home and what they’re willing to pay. In 2026, a sign in the yard and an MLS listing aren’t a plan — they’re the bare minimum.

A strong marketing plan should include professional photography and videography (including drone and twilight shots for higher-end listings), strategic pricing based on comparable sales data — not just what you want to hear, social media marketing with targeted local advertising, staging recommendations or professional staging services, open house strategy with follow-up systems, and syndication across major platforms like Zillow, Realtor.com, and Redfin.

🔑 Ask them: “Walk me through your marketing plan for a home like mine.” If they can’t get specific, they don’t have one.

5 Negotiation Skills

This is where the real money is made or lost. A skilled negotiator can mean the difference between getting your asking price (or above) and leaving money on the table — or for buyers, winning a bidding war without overpaying.

Ask about specific situations where they navigated a tough negotiation. How do they handle multiple-offer situations? What’s their approach when an appraisal comes in low? How do they handle inspection negotiations?

🔑 Ask them: “Tell me about a recent deal that almost fell apart and how you saved it.” Their answer reveals their problem-solving ability under pressure.

6 Team vs. Solo Agent

In New Jersey’s fast-paced market, there’s a real advantage to working with a team versus a solo agent. A team means someone is always available — if your primary agent is at a closing, another team member can handle your urgent question, schedule a showing, or respond to a time-sensitive offer.

That said, the key question is: will you have a dedicated point of contact, or will you be passed around? The best teams assign you a primary agent backed by a support system — not an assembly line where you never talk to the same person twice.

🔑 Ask them: “Who will be my main point of contact, and who covers if they’re unavailable?”

7 Network and Connections

A well-connected agent brings more than just real estate knowledge. They bring a vetted network of mortgage lenders, home inspectors, attorneys, stagers, contractors, and title companies. In New Jersey, where attorney review is part of every transaction, having a reliable network can save you time, money, and headaches.

For buyers, a connected agent also has access to pocket listings and off-market opportunities — homes that never hit the MLS but are available through agent-to-agent relationships.

🔑 Ask them: “Can you recommend a lender, inspector, and attorney?” If they have trusted partners for each, that’s a good sign.

8 Personal Fit and Trust

At the end of the day, you need to genuinely trust this person with one of the biggest financial decisions of your life. Do you feel comfortable asking them questions? Do they listen before they pitch? Do you get the sense they’re looking out for your interests, or just chasing a commission?

Trust your gut. If something feels off in the first meeting, it won’t get better once you’re mid-transaction with a deadline looming.

🔑 The test: After your first conversation, ask yourself — “Do I feel like they understand what I actually need?”

NJ Has Unique Real Estate Rules

New Jersey’s real estate process is different from most other states, and your agent needs to know these nuances inside and out. NJ uses an attorney review period (typically 3 business days after contract signing) where either party can modify or cancel the contract. Your agent should be coordinating closely with your attorney during this window. NJ property taxes are among the highest in the nation and vary dramatically by town — your agent should be able to explain the tax impact of every home you’re considering. Multiple Listing Service (MLS) coverage in NJ is fragmented across several regional boards (GSMLS, NJMLS, MOMLS, and more). An agent with access to multiple MLS systems will show you a wider range of properties.

NJ’s Market Is Hyperlocal

A home in Summit sells completely differently than a home in Roselle Park, even though they’re both in Union County and 15 minutes apart. Pricing strategy, buyer demographics, marketing approach, and negotiation tactics all change by town — sometimes by neighborhood. This is why generic, statewide agents struggle in New Jersey. You need someone who lives and breathes your specific market.

Team advantage: Our team of agents means you always have coverage, but you’ll always have a dedicated point of contact who knows your situation.

An Entire Support Team Behind Every Agent

Here’s something most buyers and sellers don’t realize: when you work with a solo agent, that one person is handling everything — showings, negotiations, paperwork, marketing, follow-ups, and problem-solving — all at once. Things inevitably slip through the cracks.

At the Michael Martinetti Group, every agent on our team is backed by dedicated in-house departments that work alongside them from the moment you sign on through closing day and beyond:

🎯 Sales Team: Our agents focus on what they do best — finding your next home or getting yours sold. They’re not bogged down by admin work because they have a full support infrastructure handling the rest.

📋 Transactions Team: A dedicated transactions department manages every detail of your deal — contract timelines, attorney review coordination, inspection scheduling, mortgage contingency deadlines, and closing logistics. Nothing gets missed, nothing gets forgotten. This team is the reason 99% of our deals close successfully.

⚙️ Operations Team: Behind the scenes, our operations staff keeps the entire machine running — systems, technology, scheduling, and client communications. When you call or text, someone is always available. When your agent needs to pull a comp, run a market report, or coordinate a last-minute showing, operations makes it happen instantly.

📣 Marketing Team: Our in-house marketing department creates professional listing presentations, manages social media campaigns, designs print and digital materials, produces video content, writes property descriptions, and handles targeted advertising — all in-house, all custom to your property. Your home doesn’t get a template. It gets a strategy.

This is the difference between hiring one person and hiring a team with the infrastructure of a top-producing brokerage. When your agent has operations, transactions, and marketing teams clearing the path, they can give you their full attention where it matters most — strategy, negotiation, and advocacy.

Full-service network: Trusted lending, legal, inspection, and staging partners vetted by our team and ready to support your transaction.

Community commitment: Through the Michael Martinetti Group Fund, we give back to Union County through scholarships, community events, and our annual Santa Letter Drive.
