What is your typical process for working with a new client?

Having common expectations and clear communication is key to a successful relationship and successful transaction. I find that a one-hour up front meeting to establish both is essential. By understanding a client's goals, must-haves, and timelines right up front we can align them with market realities to help clients set realistic expectations for their purchase or sale process. By educating right up front on what buyer or seller can expect to see as to inventory, pricing, and market trends in their specific category; on standard timeframes; on resources they will need along the way; and on financing options we can establish clear expectations and a strategy to move forward. Very often we discuss how (or if) a client can simultaneously buy a new home while selling their current one. There are a lot of moving parts, but easy to set a realistic action plan when its broken down to critical decision points. It’s an action-packed hour! But most times both the client and I walk away from that initial meeting knowing whether there is a “good fit” to work together and exactly what next steps are for each of us. And most importantly clients have comfort in know how the process work and that they will be well represented every step of the way.

What makes your business stand apart?

Analytics. Deep market knowledge. Our team approach to representation with all eyes on the client’s needs and goals- transaction coordinators ensuring the back-office runs without a hitch so that our team agents and can be out showing homes and advising our clients and marketing staff ensuring our promotions are being executed as planned. And in hiring the Gillach Group our clients have access to our exceptional business partners such as contractors, lawyers, inspectors, estate sales professionals, stagers, pest treatment companies or designers for any budget. You name it we have a time-tested, trusted vendor to help.

What do clients have to say about you?

“Mary and her team helped my wife and me buy a house in Newton but after seeing a number of them around Lexington, Brookline, Winchester, and Auburndale/Newton. She was consultative without being prescriptive, and patient with our deliberate decision-making process. She was candid when we needed to hear something contrarian to our expectations (which sometimes as a buyer can be lofty) but gave us the space to reach our own conclusions. Her attention to detail is outstanding. Don’t ever buy a home without having her walked through it. She’ll surface latent issues and bring to attention defects that only someone with solid experience and deep expertise could. She should also probably teach a negotiation class at the local Ivy League B-school. Her team is prompt and resourceful, and even after we had settled into our new home, continued to provide us with helpful tips. If she can be this good at buying a house, we probably should get on her docket right now to sell our home in the future!” ~ Bhrugu and Anahita

“What a tremendous team! Smart, efficient, kind, fun, responsive and knowledgeable. We have worked with a few realtors but can't think of another we enjoyed working with as much. Mary is spirited and has great ideas. Not only would I not hesitate to recommend Mary & Crew, but I already have. And I am sure they, too, will be delighted to work with the Gillach Group!” ~ Andrea

“We sold our house through Mary Gillach and she was wonderful throughout the process. She is smart and well prepared, knows the market, provided exactly the right sort of advice while acknowledging our foibles, and was incredibly data driven. She is a real pro - the type of broker that other brokers would entrust with their own properties. And, beyond the expertise she and her team bring, she is also a kind, honest, wonderful person. I could not recommend her more highly!” ~ Doug
