The Gregory James Group is a real estate brokerage in Orange County, California, run by broker Greg Toussieng. It lists and sells homes, represents buyers, and works across the county, with guides for Newport Beach, Irvine, Santa Ana and the luxury coastal and canyon communities. The company behind it is Montana Real Estate Inc, a California real estate corporation, DRE #01822046, with Greg as its designated broker under licence #01495415.
The team is small on purpose. Greg takes the first meeting and stays on the file through closing. Esther Buede, a licensed broker and Greg's wife, works alongside him and runs Choice Home Mortgage, a second trade name of the same corporation, for clients who want their loan handled in the same office. Every licence named here can be checked on the California Department of Real Estate's public lookup, and our licences page links to each record.
Who is the Gregory James Group?
The Gregory James Group is Greg Toussieng's real estate brokerage, with its office at 1820 E Garry Ave #204, Santa Ana, CA 92705. The legal name is Montana Real Estate Inc. On the DRE record the corporation holds three trade names: Gregory James Group for real estate, and Choice Home Mortgage and Mortgage Man for home loans. Greg is the designated officer, which makes him the broker responsible for the company's real estate work.
The name comes from Greg's own. His full name on the DRE record is Gregory James Toussieng. He was first licensed in California in 2005, and his broker licence was first issued in 2009.
What does the Gregory James Group do?
The Gregory James Group does three things: it lists and sells Orange County homes, it represents buyers, and, through Choice Home Mortgage, it can arrange the loan for a client who wants one.
For sellers, that means a written price analysis from recent nearby sales before anything is signed, a plan for preparing and photographing the home, and Greg running the showings and the negotiation. The selling guide covers it step by step, and the home value page is where most sellers start. For buyers, Greg starts with what you can comfortably pay and the streets you would actually live on, then tours, writes and negotiates the offer. Buyers in California now sign a written agreement with their agent before touring, and the buying guide explains what it covers.
Who will I actually work with?
You work with Greg. The person you meet at the first appointment is the person who prices the home, runs the showings, takes the calls from buyers' agents and negotiates the offers.
You meet Greg
Greg takes the first meeting himself, at the home or at the office, and stays on your file through closing.
A plan on paper
Before anything is signed you get a written price analysis and a plan for preparing, marketing and showing the home.
One calendar
If you are buying with a loan, the sale and the financing run on one timeline, so the contract dates and the loan dates line up.
Regular updates
You hear from us on a set schedule with showings, feedback and offers, by phone or email, whichever you prefer.
