Erin
O'Connor

Broker
Lead Agent
Lending Specialist

Erin O'Connor has been closing real estate deals in San Diego for over two decades. With 500+ transactions and more than $1 billion in total sales volume, he brings a depth of market knowledge that simply can't be taught — it has to be earned, one deal at a time.

What separates Erin from most brokers isn't just experience — it's the full financial stack he brings to every transaction. As a hard money lending specialist with a direct partnership with Lantzman Lending, and deep expertise in conventional financing, Erin can structure deals that other agents have to walk away from.

His specialty is Coastal North County San Diego — Encinitas, Carlsbad, Solana Beach, Cardiff, Leucadia, Del Mar, and Rancho Santa Fe. In a market where relationships are the real inventory, his network of sellers, developers, and off-market connections gives SRG clients access to properties that never hit Zillow.

Erin's reputation is built on one thing above all else: he protects his clients. In negotiation, in due diligence, in financing — he's the person you want in your corner when the stakes are high.

Mikel Palmerin — Agent, Sustainable Realty Group

Keller Williams La Jolla

Agent · DRE #02177296

Meet the Agent

Mikel
Palmerin

Agent
Construction Expert
Co-Founder, The Palmerin Group

Mikel Palmerin came to real estate through two paths that most agents never travel: a professional athletic career and a family construction business. The combination gives him a perspective on property — and on people — that's genuinely rare in this industry.

As a former professional soccer player — competing for the San Diego Sockers and KSV Baunatal in Germany's professional leagues — Mikel built a network of athletes, executives, and high-performing individuals that extends far beyond San Diego. That network is one of SRG's most tangible competitive advantages.

As co-founder of The Palmerin Group — a family-owned construction and development company founded alongside his father Ernie Palmerin, who brings 35+ years of residential and commercial construction experience — Mikel evaluates every property through a builder's eye. Renovation feasibility, ADU potential, structural integrity, construction cost estimation — these assessments happen before an offer is ever made.

Mikel's focus is Coastal North County San Diego — and specifically the investment and lifestyle buyer who wants more from their real estate team than someone who can open a lockbox. He's the person who tells you what the property can become, not just what it is today.

Our Construction Arm

The Palmerin Group

The Palmerin Group is a family-owned construction and development company co-founded by Mikel Palmerin and his father Ernie Palmerin — a veteran with 35+ years in residential and commercial construction.

For SRG clients, this means every property gets evaluated not just on price — but on what it can become. Before you make an offer, Mikel can walk the property and give you a real construction assessment, renovation cost estimate, and development feasibility analysis.

🏠

Custom Home Design & Build

Ground-up residential construction from concept to certificate of occupancy.

🔨

Renovation & Remodeling

Full residential renovation — kitchens, baths, additions, and structural work.

🏡

ADU Additions

Accessory Dwelling Units — garage conversions, backyard cottages, attached units.

📐

Pre-Offer Construction Assessment

Walk the property before you commit — renovation scope, cost estimate, and ARV analysis.

Our Lending Partner

Lantzman Lending —
Hard Money Done Right

SRG has a direct working relationship with Lantzman Lending — one of San Diego's premier hard money and bridge lending teams. For investors, flippers, and buyers who need to move fast, this partnership is a genuine competitive advantage.

Most agents refer you to a lender and hope for the best. Erin works directly with Lantzman's team to structure the deal — which means faster approvals, fewer surprises, and transactions that actually close on time.

Hard Money Loans

For investors and flippers who need speed. Asset-based underwriting, 10-14 day close, interest-only payments during the renovation period.

Bridge Loans

Buying before you've sold your current home? A bridge loan covers the gap so you never miss an opportunity waiting for your existing property to close.

Rehab Financing

Purchase and renovation costs bundled into a single loan. Ideal for fix-and-flip projects where the ARV justifies the investment.

Conventional Lending

For primary residence buyers, Erin also connects clients with trusted conventional lenders for 30-60 day close transactions at market rates.

How We Work

What We Stand For

🤝

Relationships First

We build long-term relationships, not one-time transactions. Most of our business comes from past clients and their referrals — which is the only metric that really matters.

🔍

Radical Transparency

We tell you what we actually think — including when a deal doesn't make sense. Our reputation is built on honest advice, not on maximizing commissions.

⚡

Full Stack Service

Real estate, lending, and construction expertise under one roof. You shouldn't have to piece together a team for every transaction. We handle it end to end.

🌊

Local Obsession

We live here. We surf here. We raise families here. Coastal North County San Diego isn't just our market — it's our home. That distinction matters in every conversation we have.
