Are you looking to purchase a home? We work diligently with buyers to find the right home in the right neighborhood for the price that fits your budget.  Many of our clients are looking for something very specific. We take the time to find the home that fits your specific criteria, whether it takes weeks or years! We will never try to push you into a home that doesn't meet your needs.

We were thrilled with the results when Kirsten and Frank helped us to purchase our home. They were quick to respond to all our needs and questions. We were able to sell our old house quickly and for more than we even listed it for. When I discovered a new house that had just come on the market, Frank was able to get me into it to view it on the same day and we were able to put an offer in that evening. They negotiated a great deal and we couldn't be happier. -The Dofelmiers

Relocation. Are you relocating to the Seattle/Bellevue area? We also specialize in working with relocation buyers. We'll spend time with you and show you the different neighborhoods and assess your needs and those of your family. Looking for a walkable neighborhood? We'll acquaint you with those. Need great schools? We know the best. 

Frank was a big help in purchasing our home during our relocation to Washington. Went above and beyond in helping solve and negotiate issues during purchase. Was always quick to respond and move process along. - Kevin Campbell


Listing a home is a process. We won't just throw your home up on the Multiple Listing Service and call it good. We believe that proper presentation is what gets a home sold fast and for the most money. We work with you to assess your home's condition, help facilitate any changes, repairs or improvements before we put it on the market. If the home needs staging, we'll work to get the best and most cost effective solution for you.
