Marian D’Unger, a Corpus Christi native, relocated to the Dallas area over twenty years ago starting a new life and new career! Since becoming a Realtor, she has earned the respect of her peers for her integrity, professionalism and high production. Marian, a published author and a former radio talk-show host in Dallas featuring news from the real estate market, stressed and still stresses the importance of knowing the difference between The Good Guys vs. The Bad Guys in the building industry. Her book, “On The Level…New Home Construction Nailed Down”, will answer many questions a new home buyer should be asking their builder. The value of understanding what a buyer has the right to expect, as a minimum acceptable quality, is immeasurable. She stresses the importance of knowing the “what and why” of the home’s construction from behind the walls and under flooring to proper procedures for other stages such as site prep, engineering for water injection, plumbing, insulation, post tension slab foundation (how to make sure it’s done correctly and carefully monitored), framing (a critical part of the home), as well as noting all the finish details that complete a quality home. Over the past 12 years, Marian has been conducting construction seminars designed to present a comprehensive review of the many facets of new home construction from lot prep (incl. engineering and water injection) through the final punch out of the finished home. It is not intended to be a summary of the project but a chronological check list of what is needed to build a home that meets or exceeds the project’s realistic quality expectations. Marian has received the New Home Construction Specialist (NHCS) designation from TREC (The Texas Real Estate Commission). Marian has been approved as an instructor from the commission for the NHCS designation. Marian is happy to share her expertise with other Real Estate Agents as well as Consumers. Marian is a proud member of the Coldwell Banker Apex, Realtors. Marian and her husband Gerald, an attorney, have been happily married for 32 years. They have 2 daughters and 3 beautiful grandchildren. She attended Del Mar College and is a member of St. Anne’s Catholic Church in Coppell. She left behind previous careers as an entrepreneur in the fashion industry, a public speaker for the oil and gas industries, as well as a petroleum landman. Her skills in negotiating contracts in the petroleum industry as well as her experience in sales and marketing in the fashion industry have carried over to improve her proficiency in the real estate industry. In her spare time, Marian enjoys traveling and playing with her grandchildren. In addition, she has worked for years rescuing and taking care of animals in need.


“I always receive outstanding service from Marian D’Unger! She really knows the market and gives excellent advice. She was available to show me a house with short notice and she is so knowledgeable about foundation issues. I consider her a great friend. She couldn’t be better!” – Linda Jackson

“Marian is very knowledgeable about the market, quality of the construction and the factors that are important for resale. Her level of service and commitment to her clients is outstanding! She is the best in the business.” – Jack Mendenhall

“Outstanding Service! We would use no other agent. Marian has made a significant difference each time we have used her to buy or sell. Outstanding! Extremely knowledgeable in all areas especially construction.” – Rich Pierce

“Marian and her Team were a pleasure to work with and I would/will user her again to buy/sell and properties that I am interested in moving forward.”- Donna Poplawski

“Marian does a fantastic job of teaching people about new construction.  She knows the nuts and bolts (literally) sometimes better than the builders themselves.  She also knows how to communicate this information to others on a level they can understand and appreciate.

Marian is my first call when I need information on this subject.  I highly recommend Marian and her class.” – Blair Taylor, Broker / Advisor / Manager

“As a consistent top producing agent for Coldwell Banker Residential in Dallas-Fort Worth, over 1/3 of my business is selling new construction homes to clients. A huge part of my success over the years is attributed to the training and education I have received from my mentor Marian D’Unger. She is a staple in the residential real estate industry and has by far the most comprehensive knowledge of new construction and the building process.

I specialize in new construction sales because of the knowledge I have obtained from Marian over the years. My customers are amazed at the magnitude of moving parts during the construction process and that their real estate professional has the ability to make sure the process moves smoothly. There are a ton of builders in the metroplex but there are a specific few that are truly outstanding. Marian’s education process has been invaluable to my success as a BROKER in DFW enabling me to provide knowledge and customer service to clients that very few real estate agents possess. Her classes, books, and speaking presentations are comprehensive, educational and have details that are imperative for a truly successful residential build job.

Marian D’Unger is truly the best, and has become family and an integral part of my life.” – Geoff Walsh, Broker

“In 2001, Marian and I met to discuss my new business venture as a real estate agent. After a short discussion I realized how valuable it would be for me to work with such a knowledge successful agent. As a new agent, Marian was instrumental in providing her knowledge in new construction and instruction on how to build a solid referral business. As my business continued to grow by utilizing the skills she provided, I was able, after two years, to establish my own team. My status in the organization as the number two sales person is a direct reflection of having Marian as my mentor. I will be forever grateful.” – Frankie Arthur

“Marian D’Unger (Diamond Club 2014) specializes in new home sales and construction, in fact over 70 per cent of her sales last year were new homes.  She is an expert and a speaker regarding new home construction, teaching agents what to look for in soil, laying out and pouring the foundation, treatment of the concrete, walls, rafters, windows, roof, insulation factors, etc.  In fact she has written a book on the subject and has spoken at many events.  She spoke at our 2015 Business Symposium this year and I was reminded how popular her topic is with the agents.  She truly teaches them how they can bring value to the new home construction process, and thereby the clients feel good in their agent receiving a commission.  Numerous of the well-known builders have had her speak at various conferences, etc.  There are two reasons for her willingness to share: 1) she loves the topic and sharing with agents, 2) she could always use referrals.” – Mark Wolfe, Broker

We were selling an older home with structural issues that were only discovered once our buyers did a thorough inspection. Marian gracefully helped us negotiate a reasonable compromise with the buyers' agent. She got our house sold for a good price! Would definitely use her again.

05/10/2018 - lindaj jackson

Since 1996, Marian has helped me sell two homes, and has helped me purchase 9 homes including six rental properties (most recently in 2016). She really knows how to prepare a home to show well and sell quickly. She sold our last home in 2013 in one day! She really knows local builders, understands home construction, and can quickly spot problems like foundation issues. She will tell you her honest opinion about a home and definitely puts the interest of her clients first. Marian has gone above and beyond what I could ever expect from a realtor including helping me with tile and granite selection! She really LOVES what she does and truly cares about her clients. Call Marian for buying or selling a home and you will not be disappointed!

05/10/2018 - carterxoxo

Marian is amazing! Not holy does she know the market she knows just about everyone who is instrumental in buying or selling a home. I started my home search while still living I VA and Marian worked tirelessly finding just the right areas for me. In the long run, I decided to build and once again, Marian was there to find the right builder in the perfect location. She negotiated a great deal and is continuing to advocate on my behalf as we get close to closing. This would have been so much more difficult had it not been for Marian's expertise in her field. Need a realtor? Marian D'Unger is the person to call!

05/10/2018 - JackTest

Marian provides great guidance on which features and decor provide the highest resale value. She has a strong relationship with the builders which results in them being very responsive about resolving issues. Marian provides excellent support for her clients, strongly recommended!

05/10/2018 - jennings josh

I cannot truly give enough praise and endorsement for Marian and her team. Marian is the reason we were able to move out of our first house and now we are living in our beautiful home that we had built. When we first met, it was completely by chance and she and her husband happened to be showing a home that we were just researching. From the moment we met her, Marian was warm and inviting as well as being extremely informative about looking for a new home. We knew nothing about her vast experience as a realtor and how big of a deal she is. After going home and thinking about the things she had to say about looking for a new home, we reached out to her a few weeks later. She came over, and talked to us about what we wanted and needed and we just moved on from there. In the current pre-owned market, we decided to build a new construction home instead of competing and bidding for homes. We were fully confident that Marian could help us get into any type of home we wanted, but with our lifestyle we didn't have time for bidding and losing and bidding again.
In addition to helping us get into a new home, she also sold our old home and negotiated the timelines to line up just right for us to get both done in the same week! By the way, Marian is quite the expert on new construction homes and we can't say enough good things about her advice and her patience.
She talked us off the fence a few times since we had MANY concerns, assuring us that everything was going to be great in the end. We trusted her with the biggest purchase of our lives and she did NOT disappoint. Marian is truly the best and her team will take care of anyone looking to sell or buy their next home. Her patience, knowledge, compassion, integrity and expertise is unrivaled in the Realty market. Thank you for Everything!

04/20/2018 - jorge paz

Working with Marian and her team has been always a very successful and smooth experience, She knows the Market very well and her professionalism has no limits. She can be reach at any time with any question regarding Real State and She'll have the correct answer.
I had the opportunity to work with her in several transactions; buying, selling and renting houses and the result is the same... Outstanding !!!
I really recommend to work with her and D'Unger Team, they will do the best to guide you to ensure a very pleasant experience. Thank you Marian.

I bought a Townhome last month through The D'Unger Team and I can never say enough about Frances Kwan and the team at D'Unger. They worked during all hours and fit me the best deal. I would give them a 10/10 in all areas of negotiation, responsiveness, expertise, knowledge, etc etc. This is an honest review from a buyer.

05/30/2016 - plounis1

Frances Kwan of the D'Unger team is the best realtor I have every had the pleasure of working with (and I've worked with a lot of them!). She was willing to go the extra mile and do whatever I needed help with in order to sell my property. She truly had my best interest in mind and was able to offer recommendations and advise accordingly. It isn't often that you encounter a real estate professional who embodies the very best of what the word 'professional' means. Frances is one of those people. I would highly recommend her to anyone looking to buy or sell property in the DFW area.

05/27/2016 - Blake Devillier

Frances was great! She had a definite approach around marketing my home and it paid off. The house was put on the market on a Sunday and I had three offers (all for more than the asking prices) on Tuesday.

05/15/2016 - user6590066

Nancy Pieper was recommended to me by an individual who I trust, so I called her, and I am so grateful I did!

Nancy Pieper worked tirelessly to find us a house. We had a budget, specific needs and location for a house, and Nancy sent us houses to look at every day via email. She worked very hard to set up appointments for us to look at houses, and even though it was a challenging market, WE got discouraged, but Nancy NEVER did. She kept our spirits up and just stayed focused on the next house.

She is very tech savvy, so for someone like myself who works a full schedule, its helpful to have a realtor who uses text messages and online tools such as electronic document creation and electronic signing. We are able to fast-path offers, we would find a house we liked, Nancy would text us late at night that the offer was ready for electronic signature, we e-signed, and the offer was made before the next business day. In a fast-paced market, this was invaluable.

Nancy has an excellent eye and pointed out issues with houses that were totally hidden to us. I have used many real estate agents, and have never experienced anyone who was so knowledgeable about architecture and construction. It was amazing to me how she could spot issues so easily. We were standing outside of a house I was falling in love with, and she said to me, that roof has been modified, I think that is an extension added on to this house. Careful questioning revealed the homeowner had indeed added that entire section to the house built by him. I suddenly fell out of love and was so grateful she was able to spot that.

Nancy also is a great advisor. If asked, what do you think? She was very honest with us, and would go point-by-point the advantages and disadvantages of the home. She never pushed us one way or the other but left the decision to us, but we relied very heavily on her advice in our consideration. That was another great trait about Nancy, she never pushed us into a decision.

Although Nancy is a very nice person, we found her to be a very skilled negotiator and we appreciated her efforts during a very difficult closing. Most people would have ran away screaming because our closing was so problematic, but Nancy overcome every challenge and helped to calm us during this very dramatic process.

I highly recommend Nancy Pieper as a realtor, if I could give her 10 stars, I would.

05/01/2016 - jonimm0421

Jim Newton was a big help in assisting me with the process of buying my home. He was very dependable, responded to emails quickly, and was prompt when showing properties. I would highly recommend him to anyone needing assistance with buying or selling a home and I will definitley use him again in the future!!

04/27/2016 - tiffanyganss

I was so lucky to be able to work with Frances! She made purchasing a home a BREEZE. She was readily available and willing to answer any of my questions along the way. I could not have imagined the process going any smoother. I am thankful for her knowledge and expertise in her field.

04/26/2016 - jerrygeo40

I have known Jim Newton for slightly more than 20 years and always have experienced him to be of good character and possessing a good work ethic. The home he listed and sold for us was that in which we had lived for 36 years, and he did a fine job with that,

04/26/2016 - karenktaft

I recently retired from education and wanted to move to the Dallas area to be closer to my family. A friend of my daughter's recommended Jim Newton for a realtor. I had recently sold my house in Dalhart, Texas. Jim contacted me immediately and spent considerable time in getting to know me, my family and what my needs and likes in a house would be. He set up a schedule to view houses that would meet with my convenience since I was still in the process of moving and finishing my contract with the district. After viewing the first few houses, Jim took time to discuss with me what I liked and did not like about the houses. Each time we subsequently met to view houses, each house had all my preferences. He was extremely helpful in all aspects of the viewing and purchasing process. I had never met a more caring realtor that had the buyer's interests as a priority. He processed the sale with extreme efficiency and made my purchase of the perfect house for me a wonderful experience. I intend to recommend Jim Newton to anyone I might know looking to purchase a home. He still remains in contact with me through newsletters and e-mails giving me up to date home owner's information.

04/25/2016 - rlbest4

Jim was very helpful in introducing us to the Dallas area market when we moved here in 2015. He showed us homes in several communities so we could get a feel for the area in a short amount of time.

04/25/2016 - gregorymscott1

Jim Newton sold me my current residence. He was incredibly professional helpful and most importantly; honest. This was not my first purchase but it was easily my best experience. Thank Jim

04/25/2016 - bonnielankford

Jim Newton did a terrific job of selling my condo - he was very professional and knowledgeable. I would highly recommend him for any real estate needs in DFW.

04/20/2016 - smith antonio

My wife and I were looking for a larger place to live. We just had a kid and a 2 bedroom apt was not going to cut it. Spoke with Frances, told her our budget and the area we were wanting to live in. We were able to find exactly what we were looking for and thanks to her work, the process was painless.

04/20/2016 - user32917163

We are so thankful to have had Nancy represent us in finding us a home. She worked around the clock to make sure we got what we wanted and is an expert in the Wellington / Bridlewood neighborhoods. She made the process quick and easy for my wife and I. Because of Nancy I now have a great deal of respect for a great real estate agent like her.

04/19/2016 - eaheah1012

Frances is an excellent real estate agent. She went above and beyond to help us find a home. She is knowledgable, professional, and prompt. We look forward to working with Frances in the future.

04/10/2016 - teacher2115

Frances Kwan was wonderful. She met us to show my husband and I a house and when we decided it was too small, she took us immediately to another home that I was also trying to see. We signed the lease papers right on the spot. Frances helped us through every step of the lease procedure. She even sent cookies after we moved in.

04/06/2016 - Jim Lamb8

I had an unusual situation where my house got hit by lighting and caught oin fire. I had to find a rental property right away to get my family in a house.

I have to say I was very impressed with how hard Nancy and Frances worked to secure a property in such a short period of time. It turned out to be more complex than I thought because they had to work with both a relocation company and an insurance company.

Nancy and Frances were very responsive to every request and every step of the process.

11/10/2014 - ashley l hensel

My husband and I recently used Nancy as our realtor to sell our house and also to help us purchase a house. We interviewed a few realtors to weigh our options. After our initial meeting with Nancy, the answer was clear, she had to be our realtor. She has continued to impress throughout the process. We were first time home sellers as well as first time purchasers of a pre-existing home (we built our previous house).
From the beginning she laid out the process and set expectations for us. She is the hardest working person I know and doesn’t rest until her work is done, literally. Her follow-up and responsiveness is impeccable. She is extremely knowledgeable and always was one step ahead of the other agents. Oh, and did I mention she is fun and has a great personality to boot?!
It is evident that Nancy enjoys her work and is passionate about it. I appreciate her candor and frankness, especially with the housing market the way it is today. She is a good listener and got a feel for what my husband and I were looking for in our new house. She didn’t waste her time or ours by taking us to homes we wouldn’t be interested in. Buying a home is a huge decision (the biggest single expense in most people’s lives) and selling a home can be emotional and bittersweet. Nancy put us at ease and I always knew that she had our best interest in mind. She was never pushy. She genuinely wanted us to find the \u201Cright\u201D house, not just a house so she could close the deal.
I guarantee you will enjoy your home selling/home buying process with Nancy Pieper. She is a rare breed in the Real Estate Market. Call her today! You won’t be disappointed!
