Talking to Nelson, you will feel like you have known him forever. He is the first one to openly say what everyone else is thinking, and to ask the hard questions like, "Is this house really worth that?"
That directness comes from work. Nelson runs the same LSG playbook every buyer and seller on the team gets. Pre-offer memo before every offer. Lender on the call before the price is agreed. A written game plan the buyer can read in five minutes flat. Clients close at the right number because the homework is done before the offer goes in.
Based across Andover, North Andover, and Haverhill, Nelson works with buyers and sellers across North of Boston, Southern New Hampshire, and the Merrimack Valley. Bilingual in English and Spanish, he is the point person for LSG's Spanish-speaking clients throughout the region.
Every home you see here, every alert, every saved search comes directly to Nelson. No call center. No lead pool. No middleman.
When you list with me, you’re not hiring one agent. You’re hiring the LSG operation. That means professional photography, magazine-quality copy, a pre-launch marketing push, and a full audience of qualified buyers ready to tour on day one.
I’ll price your home to the market that actually exists right now. Not the one from last spring, not the one from the appraisal you got two years ago. Real comparable sales, real days on market, real buyer demand at this exact price point.
You’ll always know what’s happening. Weekly showing feedback, offer strategy calls, and a written recap of every negotiation so you can decide with the facts in front of you.
Whether it’s your first home or your fifth investment property, my job is the same. Understand what you’re actually trying to do, find the properties that fit, and get you the deal without the drama.
I speak Spanish and English, and I’ll walk you through the entire process in whichever one feels right. Pre-approval, tours, offers, inspection, closing. Every step, every question, every decision, in language that makes sense.
When we write an offer, we go in with the LSG homework already done. Pre-offer memo, lender on the call, a written strategy for the counter. Then I’m the one walking the inspection with you and translating the report into plain language.
“Nelson is the agent I trust with my most complicated clients. He’s bilingual, he’s patient, and he treats every buyer like family, whether it’s their first condo or their fifth investment property. He shows up for people, and he does the work.”
