Find your dream home

🏠 Tennille Allerheiligen
REALTOR® | Century 21 Union | Since 2014
Helping clients navigate homeownership with strategy, honesty, and heart.

👋 Welcome! I’m Tennille.

Since 2014, I’ve helped over 100 families buy and sell their homes — earning top honors every year with Century 21 Union. My mission is simple: guide my clients with expertise, hustle, and a personal touch that comes from walking the path myself.

💼 From Fortune 500 to Front Porch Dreams

Before real estate, I spent 16 years in IT sales, working with some of the world’s largest corporations. Then I paused my career to raise my kids — and that’s when my passion for real estate turned into a mission.

🏡 My First Home Story: From $0 Down to Long-Term Investment

In 2003, I bought my first home with $0 down and a 5-year ARM. Life happened — and I learned fast. Refinance. Loan mod. Eventually, I turned it into a rental that now pays for itself and then some. That hands-on experience drives how I guide first-time buyers and investors alike.

🎓 Earning My License — With Pressure On

I dove into real estate while raising my family. It was a stressful time — but failure wasn’t an option. I passed, licensed, and never looked back.

🤝 Learning from the Best

Partnering with a top-producing agent allowed me to learn the business the right way — by doing. For five years, I was in the trenches, gaining hands-on experience and building my sphere of influence. When my mentor retired, I was ready to take on this business Solo!

✨ Going Solo in 2020 — In the Eye of the Storm

My first solo listing? Right as the pandemic hit. PEAD forms. 6-foot markers. A frozen market. And somehow, through hustle and heart, I earned CENTURION in 2021. Boom.

🏁 Guiding You to the Finish Line

By offering my services, I’ve had the privilege of helping clients from all walks of life — from first-time homebuyers to seasoned sellers, from investors to trust executors. Whether it’s a distressed property needing vision or a pristine, turn-key home ready to go, I bring experience, strategy, and compassion to every transaction.

I also come with a trusted team of professionals to make your journey smoother — electricians, roofers, landscapers, plumbers, and more — ready to help prepare your home for the market. For buyers, I work closely with some of the top lenders in the industry to provide strong financial guidance and options.

Backed by the leading Century 21 office in the South Bay, you can rest assured that you’re in the best hands. I’ll guide you through every step, negotiate fiercely on your behalf, and help you cross the finish line with clarity, confidence, and success.

Let’s make your real estate goals a reality.

💡My Real Estate Philosophy

Real estate isn’t just about properties — it’s about people.

Every transaction has a story behind it, and I take pride in helping clients write theirs with purpose, clarity, and success. Here’s how I approach every deal:

• • Relationships First
    Real estate is personal. I build long-term relationships by listening closely, communicating clearly, and always showing up for my clients.

  • Know Your Numbers
    Whether you’re buying or selling, understanding the financials is key. I’ll help you break down every cost, benefit, and opportunity — no surprises.

  • Stay Local, Stay Focused
    I specialize in the South Bay. When I know a market inside and out, I bring unmatched value to the table.

  • Take the Right Risks
    I’m not afraid to think outside the box, negotiate hard, or push for creative solutions. Success often lives just outside your comfort zone.
