Erin Corwin

Spire One Realty

Looking to sell your property, buy a new home, or just need some expert real estate advice?

About
I have spent more than 25 years in Puget Sound real estate, and I have lived here my whole life. I represent buyers, sellers, investors, and builders through The Corwin Group, brokered by Spire One Realty.

My foundation was built within some of Seattle's top-producing teams, where I directed operations, marketing, and transaction management behind thousands of successful real estate closings and hundreds of millions in annual sales. I worked through the 2008 housing crisis and the COVID market shift, and that experience taught me to anticipate obstacles early rather than react to them late. Earlier in my career, I worked in condominium and community association accounting, supporting a portfolio of more than 80 associations. That is where my fluency with association budgets, reserves, resale certificates, and governing documents comes from, and it still benefits every client today.

I work across single-family homes, condominiums and common interest communities, manufactured homes, multi-family, land, new construction, and estate and trust sales. I also handle relocation clients and VA-financed transactions.

What that looks like for you:

I know the documents. Resale certificates, budgets, reserve studies, title reports, septic records, and permit history all carry information that affects your decision. I make sure you know what to look for and what questions to ask.

I price with data. You get comparable sales, days on market, and an honest net sheet so your decision rests on real numbers.

I get ahead of problems. Financing conditions, inspection findings, and repair negotiations are handled while there is still time and leverage to solve them.

I answer. You hear from me directly, and you always know where your transaction stands.

I serve the greater Seattle area and communities throughout Washington State, including Snohomish, King, Pierce, Thurston, and Kitsap counties.

If you are thinking about a move, I am glad to walk through your options and the numbers before you commit to anything.

Lake Stevens, WA - Jul 16, 2026

We had an excellent experience working with Erin Corwin. From start to finish, she was professional, responsive, and always on top of every detail. Her communication was outstanding. We always knew what was happening and never had to wonder about the next step. She made what could have been a stressful process feel smooth, organized, and positive. Erin truly had our best interests in mind and went above and beyond to ensure everything stayed on track. We couldn’t be happier with our experience and would highly recommend Erin to anyone looking to buy or sell a home. Thank you for making the entire process such a great one!

I couldn't have asked for a better broker. She keeps everything positive and easy going, while explaining everything in a way that is easy to understand for those not familiar with realty. Very responsive, and flexible, she will help get you what you asked for as soon as she can. I would use her as a broker again. 5 stars!!
