Bill helped us purchase a home in Lewes, DE after completing retirement from our Lone Star Quiltworks business. He was truly amazing to work with and probably the best realtor we have ever dealt with for a home purchase. His follow through was amazing.

I cannot say enough about how amazing Bill Cullin is! He is experienced, knowledgeable, friendly, and competent. He spent about 2 years with us as we searched for our perfect beach home away from home. We finally found it!!
In between working with Bill, we stumbled across a different agent who was pushy and did not listen to our needs. We worked with that agent 1 time only. But we went back to Bill again and again. No matter how much time elapsed, Bill was always happy to continue showing us homes and never pressured us to decide. His expertise in home building, decor, repairs, comps, and the Rehoboth area is outstanding. We live out of state, and he was willing to preview homes for us first. And we trusted his assessment 100%. In fact, the home we ended up purchasing, we did not see until home inspection! We were not disappointed, and our home is absolutely perfect for us. Bill's patience with us was remarkable! If we ever need to sell our beach home, Bill Cullin will be our agent.
