She was AMAZING! She was extremely knowledgable about the areas where we wanted to purchase. She was always available an swering our phone calls, emails, and text. She was flexible and made herself available to show us homes! She listened to the details that were important to us and found us a home that checked all of our boxes. She was so compassionate, supportive, and encouraging. She made buying a home an amazing experience! Thank you!

Traci Evans, Huntingtown
Thank you seems so inadequate. She took our dreams and made them a reality! She gave us a comfort we didn't think we co uld have during this process. She always made sure to leave no stone unturned in making sure every detail (no matter how small) was perfect for us. Her knowledge of the area and the market was extremely beneficial in our decision making. She is 2nd to NONE and will not stop until everything is perfect for the clients. Thank you!

Patti came to see my property on a Monday evening. She had a CMA ready by that Wednesday and a buyer lined up the next d ay. The entire process, from my initial phone call requesting information about “ If I were to put the house on the market?” until signing closing documents, took five weeks. I am very happy with every aspect of my home sale. She did a phenomenal job and made everything painless. I would, without a doubt, recommend her to any of my friends, family or business associates in the market to sell their home.

Patti truly demonstrated a high level of experience as a realtor and extreme knowledge of the Calvert county area and sc hools! There was no question that she couldn’t answer, or detail that she missed! She worked through the holidays and weekends to ensure we visited house, and provided great insight of each every home we saw. More importantly, she was very patient with our decision making on what house we wanted!!!

Patti is awesome to deal with. Very professional and looks out for her clients. She had a tuff agent to deal with for the buyer of my house and the seller of our new house. She fought hard for us and looked out for our best interest. Would recommend her to anyone looking to buy or sell a house.

Patti went above and beyond in every aspect! She thoroughly explained everything and made sure I was choosing the perfe ct home for me and my daughter. She made my first time purchasing a home a great experience.

Cassie and Patti went above and beyond to get our home sold. I’m confident no other team would have put as much care a nd thought into the relationship or sale. They were knowledgeable on staging, trends in the market, comps, and happily walked us through the inspection process. We were incredibly thankful to have them on our side. Without them, I’m not sure we would have sold the property.

First time buying a house and it couldn't have gone better thanks to Patti. Thanks for making this process perfect and b eing so understanding and cooperative with all my questions throughout the process! She was there for every step of the way and worked tirelessly to make sure everything went smooth. Buying a house can be overwhelming but with an agent like Patti there's nothing overwhelming about it!

Patti O’Donnell was outstanding to work with. Patti was very conscientious. Patti always returned calls within the h our. If Patti couldn’t, I got a txt when I could expect the call. Our house sold in 11 days! The advertising package Patti O’Donnell prepared was first rate (brochures as well as photos and video). Bottom line, if you are looking for a realtor who will provide you with the best suggestions (staging,reno, etc), comps and pricing suggestions that are realistic, Patti O’Donnell is the realtor to engage. Patti O’Donnell will tell you what works, and it does.

Patti listened to my every detai and wishes for over a year. Patti has tremendous patience and understanding, as i put h er through a lot with some personal issues of my own. She considered my every opinion and made very helpful insights when requested. she placed me in a position where i feel very economically comfortable but extremely delighted with the residence i have occupied. i could not have any higher recommendation for any other realtor. I am so very happy and thrilled to own my own place where it feels like home and i feel comfortable being able to afford it. Additionally, I worked a lot with Pat Jenkins as my loan officer and she was patient as well as informative, knowledgeable and friendly!

Patti helped us buy our house 3 years ago. She was so amazing we knew we would use her again. We contacted Patti when we were ready to sell. Patti went above and beyond with sale of our home. She is the best! It sold quickly and she handled everything in record time.

Patti was great! She got a full price off on my house. The communication couldn't get any better. I will use Patti in t he future and will recommend her to others.

I don't think I could find another fair and honest agent to represent me and help guide me along the way quite like she did. She has a lot of experience and knowledge in her field which I appreciate. She made recommendations on how to sell our home quickly and she did just that. We were thrilled to have our home under contract in less than 30 days. I would hands down recommend her to anyone in the market looking to either buy or sell their home. She does all she can to make her client's experience both enjoyable and effortless! I haven't encountered a person yet that has regretted using her as their agent! She's great :)

Patti was simply a great person to work with. She always answers your questions and gets back to you as soon as she can with phone calls, and always seems to be very happy when she shows a house. I would recommend patti to any friend or family member if they wanted to have a great home buying experience. Patti never made it seem stressful, as with buying a home can be, it was a delight to work with someone like her and she will always come highly recommended from me.

Conventional wisdom tells us to not do business with friends, however due to our 20 year friendship with Patti O we knew first hand of her integrity and strong work ethic. Listing with Patti was an easy decision ; but once we were under contract we realized it was a WISE decision as well. We had wonderful buyers that came with agent unfamiliar with the area. This is when we learned how important the agent WHO represented us was. Patti made certain all required inspections and repairs were done promptly and correctly and communicated with a rather frustrating title company as well. By Patti being PROACTIVE were able to close quickly to satisfy the buyers wishes. Patti comes with the knowledge of not only WHAT need done but WHO to contact. This is so helpful for a seller when they first list their home and also once under contract. She can assist sellers with item such as landscaping, power washing, well, septic, electrical to name a few. Patti also provides quality pictures , video and brochures. Patti understands that selling or buying a home is a stressful life event and is always available when you need her. We can recommend with out reservation Patti O'Donnell at Century 21 NM to anyone looking for a TRUE real estate professional.

My agent, Patti O'Donnell is simply put - the best. She had the right mix of being personable and professional. I made the right choice for my realtor and will refer her as often as I can. Patti understood what a difficult decision and process it was going to be for me and she was there every day any time that I needed her. Thank you Patti!!!!!!!!!!!!!

Patti O'Donnell is an agent that is always available. Of course, they're are times when you call, it goes to voicemail, however, she calls back with in a few minutes. Patti was scheduled to be on vacation at the tail end of our process but she was never out of reach. I felt very guilty about contacting her while she was on vacation but she always assured me that I may call her anytime. Patti never made me feel like I was interrupting her and I was never rushed. She even came back from vacation early just to be there with us during the settlement. I would absolutely recommend this Broker and Agent to anyone who wishes to deal with someone who really cares about what you want and will go over and beyond to make that happen.

Janelle Sears, Lothian
Patti O'Donnell was very thorough when explaining everything about the home we were buying when preparing the contract. From the deposit and how it was handled to her timely scheduling of inspections and the negotiating of contracts. We had an issue with selling our home which held up buying this home and Patti kept us up on everything and helped us straighten out the problem.

Patti O'Donnell is an awesome real estate agent and I would recommend her to anyone looking to buy and/or sell a home in the near future. Her knowledge of real estate buying and selling made our sale and purchase go smoothly and her attention to detail is amazing. She stayed in touch with my husband and I throughout the entire process. If we ever decide to move again, we will definitely use her services again.
