The best you can find in the area!

The best you can find in the area!

When I started my home search, I had no idea what I was getting into. Warren Nass turned what could have been an overwhelming experience into one of the most educational and empowering decisions of my life. From day one Warren took the time to genuinely understand what I was looking for; not just the square footage and price range, but my lifestyle, my long-term goals, and what kind of community I wanted to be part of. He never pushed me toward something that didn't fit. When properties didn't check the right boxes he said so clearly and moved on, which saved me enormous time and emotional energy. What sets Warren apart is his strategic thinking. When we found the right property in San Pedro, he didn't just submit a number; he helped me frame the offer in a way that spoke to the seller's situation. Instead of fighting over credits in escrow, he advised me to position the offer as a buyer willing to take on the property as-is, which resonated with the trust sale seller in a way a higher competing offer might not have. That approach worked. He also fought for me in ways I didn't expect. When the seller's agent called Warren directly about a previous deal falling through on another property I had interest in, he moved immediately and strategically while protecting my position without creating unnecessary friction. Warren is responsive, honest, and genuinely in your corner. He never made me feel like a transaction. If you're buying in the South Bay or Southern California area, I cannot recommend him highly enough. He helped me find not just a house but a home with real long-term potential; and I'll be working with him again should the time ever call for it.

Best Realtor Ever

Warren Nass was the best I don’t think I could have asked for a better realtor! I was nervous about selling my mom’s property! The home needed a lot of work. Warren was so helpful with preparing the property for sale, his negotiation skills were awesome also! I received a great price for the property all do to Warren Nass! I would recommend him any day! Even my mom’s neighbors were highly impressed with him. Thank Warren Tammy B

Amazing Agent!  Came back to sell 15 years after buying from him!

Amazing Agent! Came back to sell 15 years after buying from him!

Warren and Cathy Nass are amazing! Fifteen years ago, I bought my condo through them. It was a wonderful experience. Both were upfront, honest, and did their best to make my experience as a buyer comfortable. I told them then, when I was ready to sell, I would reach out. I was so glad I did. Having an agent you can trust is paramount! During my selling experience, I had emergency surgery, they were on the spot, working with my sister as I was relocating out of state, to ensure my condo would be empty, presentable, and the paperwork was completed. As we went through the selling process, Warren and Cathy were in contact with me. Anytime I had a question, or they needed an answer. The sale went smoothly as it could, with my health issues, and relocation out of state. We were on the market for two days and had our first offer, day three brought a backup offer. They are the agents, I wish I could bring with me, when I buy a home up here in Washington! Thank you again, from the bottom of my heart Warren and Cathy, we appreciate you, your expertise, and help!

Great service, great communication, great sale!

Great service, great communication, great sale!

We interviewed a few agents for our listing and right away Warren and his partner, wife Cathy Lee, stood out. They both had amazing energy, came over prepared to the meeting and with their knowledge and confidence, convinced us they would go above and beyond to sell our property. And they did! They helped us prepare the property for listing, helped with yard work, held open houses, helped take out trash cans, and within a week of our listing going live had, multiple offers for us. We were extremely satisfied with our transaction and you will not regret choosing Team Ness for your real estate transaction!
