the edge you need to get want you want in this fast paced market

the edge you need to get want you want in this fast paced market

Responded promptly, excellent contacts and guidance, trustworthy - always felt she was protecting my interests. Perfect agent if you are aggressively searching for a home. Excellent eye when touring a home - expresses concerns when valid and provides great insight on houses' potential. Gains a quick understanding of what the buyer wants and doesn't try to "sell" clients on a property that is not a good fit. Definitely keep doing independent searches because the MLS won't show everything and sometimes lags. The agent is most important for the negotiation portion of the deal and the contracts/documents. Though you may wind up finding something you like on your own, Dianne is great at researching a property and comparisons, being honest about what it's worth, and helping you make a strong offer.

Phenomenal realtor

Phenomenal realtor

Working with Dianne was an absolute pleasure! Her experienced insights into the real estate market gave us confidence in our investment. Her genuine approach in making us feel comfortable in the entire nerve racking process of buying a home made it stress-free. Since we were buying a newly constructed home, she guided us diligently through the process and extended her expertise with minute details which we overlooked. She made sure that nothing was left unchecked by the builders from the beginning to the end. If you’re looking for a phenomenal experienced agent who understands the local market and will guide you through every detail, look no further! We highly recommend her!

Knowledgeable guide and open communicator

Dianne came prepared with market research to provide a recommendation on the listing price. She kept communication open for when open houses would be scheduled, feedback, and on any offers that were on the table. She was knowledgeable and able to help guide decisions/explain each type of offer.

Diane was a true blessing 🙏🏽

I cannot express enough how grateful I am for the incredible support I received from Diane Platt and her team at Patterson Schwartz. From the very beginning of my home-buying journey, her exceptional communication skills stood out. Diane made it a point to keep me informed every step of the way, answering all my questions promptly and thoroughly. Diane was not just a realtor; she was a true partner in the process. Her expertise and guidance were crucial in helping me navigate what can often be a stressful experience. She was always available, whether it was a quick phone call or a late-night email, and her positive attitude made the entire process feel seamless. What truly sets her apart is her genuine care for her clients. She took the time to understand my needs and preferences, ensuring that I found a home that was perfect for me. Her attention to detail and commitment to my satisfaction made all the difference. I wholeheartedly recommend Diane Platt at Patterson Schwartz to anyone looking to buy or sell a home. She and her team are nothing short of phenomenal, and I feel incredibly blessed to have had her by my side throughout this journey. Thank you, Diane, for everything! -Yahkia

Top notch realtor

Top notch realtor

I would recommend Dianne to anyone looking to sell or purchase a home. She is very knowledgeable in her profession. I case was slightly different pertaining to the decision of selling. She is very caring and understands her clients. She also provided contact information for movers, contractors and painters-all of whom provided excellent service.

Dianne far exceeded all expectations!

Dianne far exceeded all expectations!

Dianne far exceeded my expectations for an agent. She not only had our house sold in a handful of days, but provided support through every step of the process. She met me at the property to landscape, clean the garage, organize closets, and clear clutter. She did everything from making Goodwill runs, listing items on Facebook marketplace, compared prices for different services needed, and set up people to pick up items they purchased. She communicated daily and responded immediately to any questions I had without hesitation. She was always prompt, honest, kind, respectful, and I could trust anything she said to be true. Dianne was more than an agent, she was a friend. I had not lived at the property in six years due to divorce, and she came with me when I went to remove my items. I have already recommended her to all my friends and family because I could not think more of her as a person, as well as an agent. If you want to ensure the perfect sale of your home, Dianne is the agent you need! She is incredible and will make sure to remove the stress from you while she confidently handles everything. Simply the best experience I could ever ask for in a less than ideal situation for selling my home. Thank you, Dianne! I will always use you for all my real estate needs.
