from Valparaiso Indiana

"I highly recommended Double Diamond Realtors if are looking to buy or sell. They had people looking at my house before it was even officially listed. My house sold after less than 24 hours on the market. Double Diamond went above and beyond. We had no issues finding the house of our dreams and Double Diamond could not have made it go any smoother. My realtor couldn't have made it any easier knowing what we were looking for and getting our house sold."

Debra and Vladimir S.

“We have bought and sold houses in Michigan, Florida, Nebraska, and Indiana. Our experience with Jennifer Williamson at Double Diamond Real Estate, has been above and beyond any other experience. Jennifer was always available to answer any questions and extremely helpful. Our closing hit a hiccup, the day of closing, on the Seller’s side. Jennifer threw on her Super Hero Cape and saved the day. We were able to close that day because of Jennifer’s actions. Why would you ever use any other Realtor?!”


“Jennifer, I wanted to thank you for being such a wonderful realtor while my house was listed with you.
You were always prompt in answering any question that I had via email, text or phone call and that means a lot. I have sold several houses in my lifetime and have had very good Realtors but you by far were so much better. Thank you for all your help!”

Debra S.

“Even your clients from years ago think your awesome! We too have bought and sold several houses in several states and think you’re the best.”
