“good job, done professionally and as expected.”

Ron Butt

“Worked with Keith for many years. Always professional and ready to answer any questions that we had. Would recommend him and his team to friends and family.”

Dennis Cartwright, Oshkosh

“From first contact Keith was responsive. We were active online because of living out of state and requested several specific house showings on two trips. Finally we asked for suggestions because available online information was not kept current. C21 Affiliated used their resources and and suggested houses we had not found. We selected four from their list, met at the closest. Was impressed, toured one other listing then settled on the first and made an offer. Keith handled the issues that surfaced and led the process to purchase and close. Thank you Keith and your Affiliated team.”

“Keith Sippel was great to work with. He made us feel more relaxed about the whole process. He was able to get us an offer we accepted in 2 days. Overall it was a great process of selling our house.”

Megan, dale

“Keith was both knowledgeable and offered assistance beyond what was expected.”

Rod Fredrickson

“Keith Sippel encapsulates what makes Century 21 Affiliated First Realty great. Incredibly knowledgeable and eager to share his knowledge. The friendliest person you’ll ever meet. Timely and considerate. He helped us not just buy a house, but evaluate what we really wanted in a house. He also made sure we knew what a smart offer would be on the house we ended up purchasing, and helped us to make requests of the seller that probably saved us a lot of trouble down the line as the new homeowners. I can’t possibly recommend him - or his firm - enough.”

Jesse Dunsmore, Appleton

“I will recommend Keith Sippel to anyone looking to buy or sell a home. Always professional, he gets results!”

Jonathon Wendt Appleton

“The sale of the house went perfectly and according to plan”

Chris Dubey

“Keith was extremely knowledgeable regarding homes and was quick to follow up on any homes I wanted to see. He was able to show a home with little notice. Most importantly he followed through from the time of a sign offered to the time of closing. I will recommend him to anyone that is interested in buying or selling. I was working with another realtor from another agency and was dissatisfied with her follow through. Keith allowed me the time to talk through pros and cons of home and write an offer that was acceptable to me and the seller. Helped me determine a fair price for home. Keith took care of contracts and worked with financial institution and title company. He arranged everything and was able to close on the house sooner than anticipated. Keith gave me a list of home inspectors. ”
