I'm looking at a bouquet of flowers that were just delivered. They are from a past client and friend of mine. They recently sold their home through an agent that I referred them to. Although it's difficult to hand our clients off to someone else, sometimes we have to. In this case, the home was in Idaho. I've had numerous clients suggest that I get licensed for Idaho, but I've got my hands full with Spokane County :)
The best part about referrals is that they have no boundaries. I can refer someone to another realtor anywhere. If someone is selling a home here in Spokane and moving to New York I can contact someone for them, explain their preferences, and match personality traits. Instead of a shot in the dark I can interview realtors for them and help them make a good decision.
So remember, your realtor can help you with any transition regardless of the state in which the purchase or sale will take place. The greatest compliment is always a referral!
