From Temecula Valley wine country to the San Diego coast, I represent buyers, sellers and investors in Southern California's most coveted communities, with the discretion, market knowledge and negotiating strength that significant properties deserve.

I'm Andreea Horja, Broker Associate and founder of Vantage Key Real Estate, powered by eXp Realty. I'm a passionate, knowledgeable broker dedicated to guiding buyers, sellers and investors across Southern California's most sought-after communities with personalized attention and expertise.
I bring a steady, detail-focused approach to every transaction. Clients know me as determined, reliable and detail-oriented: dedicated, results-driven and a strong negotiator on their behalf. I stay consistent from our first conversation through closing, and you can always count on honesty, clear communication and an unwavering focus on your needs.
My background is in the traditional brokerage world. I spent nine years with Coldwell Banker in Murrieta before earning my California broker's license in 2024 and launching Vantage Key. I came to this country from Romania with a law degree from Cluj, and that training still shows in how closely I read every contract and how firmly I negotiate.
Fluent in English, Romanian and Spanish, I serve a diverse clientele and make sure every detail is understood. I represent buyers, sellers and investors across San Diego, Riverside, Orange, San Bernardino and Los Angeles counties, from coastal residences to wine country estates and everything in between.
Whether you're a first-time homebuyer or a seasoned investor, you'll always know what's happening and why, and you'll never feel pressured into a decision that isn't yours to make. Buying or selling a significant home should feel exciting, smooth and controlled. That's what I deliver.

She guided my husband and me through every step of the process, taking the time to explain everything in detail. She worked within our budget and helped us get a great deal — I would highly recommend her to anyone looking to buy or sell."
"Andreea helped me and my fiancé buy our first home together in Temecula. She was extremely knowledgeable, honest and upfront, and most importantly she answered every question we had."
"One of the top real estate agents here in the Inland Empire. She got our house in San Jacinto sold in less than 10 days, and then helped us buy our next home too."
