About DC House Smarts

DC House Smarts Team:

Marcie Sandalow and Catarina Bannier have been working together as a team since 2011, though together they have been in the business for over 34 combined years. In previous lives they were in the marketing and journalism fields, and bring these areas of expertise into play while promoting their listings.

Over the years they have helped hundreds of clients both buy and sell properties in the local DC/MD/VA marketplace.


“My husband and I recently sold our house in the East Bethesda area — and had the good fortune of doing so with the expert help of Marcie Sandalow and Catarina Bannier. Marcie came recommended to us through a trusted neighbor, and it didn’t take long to see why. She and Cati are the perfect team. With their combined skills and knowledge (awesome in their breadth), their attention to detail, and their upbeat, accessible manner, they were able to meld an otherwise nerve-wracking series of events into an orderly, manageable process.

“From the initial meeting through closing, Marcie and Cati were there for us, providing expert advice on any number of fronts and coordinating a dizzying array of visits to our home with minimal disruption. They looked out for our interest every step of the way while maintaining the highest level of integrity. There was not a phone call or email that didn’t get answered — they were efficient and thorough in every respect. And all of this with good nature and easy-going interaction. Our house sold within five days of listing.

“I cannot recommend Marcie and Cati highly enough. As I told them after settlement, I would recommend them to strangers on the street…and I meant it.”

- Rita Doherty, Bethesda

“Cati, and her partner Marcie, are experienced agents with all the local knowledge, strategic negotiation skills, and interpersonal skills one desires in an agent. After months of patiently looking at apartments with me, my team jumped into action when my dream apartment went for sale at 4PM on a Friday. In DC’s competitive market, we knew we had to move quickly. By Saturday evening, I’d seen the apartment twice – once with daylight, once at night. I’d also received a helpful collection of comps from my team. By Sunday, we’d put together a competitive and strategic offer. And, by Monday at 2PM, Cati and Marcie had gotten me a signed contract at the price I wanted to pay! They continued to guide me through the closing process which was remarkably smooth. Exactly 30 days after my offer was accepted, I got my keys! I look forward to working with them when I’m ready for my next house in a few years.”

- Rosie Rauer, Dupont Circle
