Marta Walsh
We know because we counted all 39,539 of them — every $2M+ listing since 1998. That research is how we price, and it’s published free on this site.
Marta came to Arizona luxury real estate from Wall Street — years of trading and market-making that changed how she prices, negotiates, and reads a market. She works primarily with sellers, alongside Matt Walsh, who runs the marketing, research, and technology behind every listing. Fifteen years, two people, one standard.
Original Research · Updated August 2026
One Shot analyzes every $2 million-plus listing ever entered in the Arizona MLS — 25 years, 29,322 selling campaigns — with the data rules and methods published in full. No other agent in Arizona has done this work. We give it away.
What it means for your home
Above $2 million, an asking price isn’t a prediction — it’s a survival strategy. The buyer for a distinctive property arrives on their own schedule; the launch price decides whether your listing is still credible when they do. We price from the whole record, not three comps and a feeling.
How we price a luxury homeYou're in the half the research describes — and it usually isn't bad luck, and it usually isn't the house. Wrong price strategy, weak photography, narrower exposure than you were told. We've taken listings that sat for years and sold them in days.
"We used another broker for a year before listing with Marta and Matt and were very pleased with the change. They never pushed for a concessionary sale — they felt our home was priced correctly. This rang true when it sold." — Pam & Glen, Paradise Valley

Client Reviews
“Matt and Marta are truly the best realtor team! They've sold 2 of our houses, helped us buy 2! A pleasure to work with, easy to approach, very knowledgeable plus able to handle my craziness when the deal is close at hand.”
“We have used Matt and Marta on at least three separate occasions. Each time they were very professional and diplomatic when it came to working with all parties to broker the best possible deal! They were extremely good at making sure the legality of the sale was done right. Worth every bit of the commission.”
“Working with Marta and Matt Walsh to sell our Scottsdale home was an outstanding experience. They were knowledgeable, professional, responsive, and a pleasure to work with from start to finish.”
“When we first listed, we chose a well-known 'Team' company. Few showings. We took our house off the market for the summer. When it was time to re-list, one agent stood out — Marta Walsh. She said the photos weren't quality enough for a luxury property like ours. She was right. We appreciate Marta's cheerful tenacity and Matt's willingness to try anything. They always listened and stuck with us through a lengthy, tough market.”
“Marta was always on top of everything. When I would call to check on something, it usually had already been done, from arranging services, to letting in Fire inspectors when the buyers Agent failed to show up. Always easy to get a hold of and never lets anything slip through the cracks.”
“I very much enjoyed working with Marta and really appreciated her professionalism, knowledge and attention to detail. She provided great market insights and produced excellent marketing materials. She handled both my residential purchase and the sale of my existing property which she sold in just five days so that I was able to purchase and close within the same week. She definitely managed the process and kept it all on track!”
“Outstanding! Marta and Matt have been the best realtors we've ever worked with. Having bought and sold 16 homes all across the US, we've never experienced such professionalism and expertise! They made selling our home easy!”
