Client Testimonials:

“Bill was extremely timely in providing us information - his response time in returning calls or texts was often within minutes and never more than a few hours.  We were located out of state, and it made the process so much easier to have someone on the ground in Rehoboth researching things for us and getting back to us quickly. I recommend Bill Cullin’s service to anyone who is selling or buying a home.”  Gavin and Emilee D.

“We have bought and sold many homes in the past.  We recently sold our Rehoboth Beach condo and Bill Cullin was our agent.  He is the absolute best! He goes the extra mile. Our condo was sold in less than two weeks at full asking price and Bill left no stone unturned throughout the process!”  Lynn and Alex N.

“Bill is an excellent agent.  Very professional, trustworthy, and always available via phone, email or text to answer any questions or give any updates.  We live in NY and were selling in DE so we weren't there very often.  He always went that extra step to make sure things went smoothly. I would definitely have him as your agent!!! you won't be sorry!!! Janet and Rich P.
