I have used Craig Diemer for several real estate transactions.  Craig has handled selling my homes as well as my purchases.  He brings the utmost professional approach to each transaction.  He provides complete services from Appraisals, Lenders, Home Inspections, Warranties, as well as Settlement Attorneys.  He is well versed in the market conditions and gives a fair and honest assessment throughout the process.  My family has complete trust that Craig will provide the expertise needed for our real estate needs.  We recommend him highly to all family and friends.

Craig Diemer was our listing agent when selling our home and he is the
best! He was thorough, professional and honest. He was always
available to take our call and answer our many questions. He kept us
up to date on showings, inspections, closing details, ect. Craig was a
true and trusted advocate during the entire process.

I have had many real estate “dealings” with Craig over the past 20 years. (Buying, selling, and brokering.) He has been consistently reliable, fair, responsive, and “brutally honest.” He is very receptive to phone calls or texts with any “silly” questions that I come up with. I have referred him to my family and friends, and no-one
has been dissatisfied with his service.

We would like to thank Craig Diemer for his expert service that stretches over 20 years. Throughout which time, he has bought and sold homes for three generations our family. His expansive and impressive history of exceptional work is second to none. Buying, selling, and investing can be extremely daunting, but we have been so fortunate to have him there to walk us through the process and make big decisions seem easy. He has always been straightforward, helpful, and has an abundance of knowledge on current market trends. However, it’s his sheer dedication and his close attention to detail truly sets him apart from the rest. Years ago, we confidently began recommending him as an excellent realtor and broker to our friends, family members-workers, and acquaintances, as we affectionately referred to him as a trusted “friend of the family.” The only difference now is the fact that we no longer consider him just a “friend” of the family but actually our “family” too.
