follow us on social media


McKinney’s Favorite Realtors®!  Monica Szewczyk and Julie Williams formed Texas Property Sisters, LLC in 2013.  Following successful sales careers in corporate America, the two decided to take their business experience and team up in Real Estate. 

Monica Szewczyk

Monica started her career working for a large hotel chain. She then moved into sales and sales leadership roles for a global training and consulting company in Dallas.  She developed excellent sales, interpersonal and negotiation skills during this time working with top business leaders in the areas of sales, service and leadership training.  When her second daughter was born, she stepped away from the corporate world and became a successful entrepreneur with a national jewelry company where she was recognized for top sales for many years.   

Julie Williams

Julie worked for several high-tech firms in the global sales arena including Hewlett-Packard, Dell, and Microsoft.  Her clients were Fortune 100 companies such as Hertz, EDS, Wal-Mart, Exxon, JC Penny, 7-11 to name a few.  As a sales manager, Julie developed strong people skills and worked on large contract negotiations.  She was recognized as a top performer at each of these companies.

Both of the “sisters” have lived in McKinney in the Stonebridge Ranch area for more than 20 years.  Monica and her husband, Todd, have two daughters.  Julie and husband Jerry, have 3 daughters, 10 grand-children and 1 great-grandchild.



Since forming Texas Property Sisters, Julie and Monica have enjoyed great success.  They have been named Top 25 Women in Business in McKinney, Living Magazine Reader’s Choice Best Realtors in 2019 and 2022, Reader’s Choice Favorite Realtor in 2020, 2021. 2022 and 2023, Real Producers Award for Top 1% of North Texas Realtors in 2022 and 2023, D Magazine Best in 2023 and Top Producers and are consistently in the top team sales for their local Brokerage Office. The Texas Property Sisters have been featured numerous times in both McKinney Living and Community Impact magazines.

Read the latest McKinney Living article about the Texas Property Sisters.



Julie and Monica are both licensed Realtors® which means that they are members of the National Association of Realtors subscribing to a strict code of ethics, professionalism, and knowledge of the local real estate market.  They are required to complete continuing education to stay up on the latest real estate laws, contracts, and policies.  Additionally, both Monica and Julie are Accredited Luxury Home Specialists (ACHS).

There are several reasons to work with The Texas Property Sisters Realty Group including:


Julie and Monica will identify the right property for you based on your budget and needs. Their knowledge of the local market helps them evaluate properties to ensure they are priced accurately.

Buying or selling property usually requires reading and signing financial documents and legal forms. The paperwork may be different for each market and done per an area’s laws and regulations. Any unintentional mistake or delay can be costly or lengthen the process of selling or buying a home. Monica and Julie are experienced in dealing with these requirements and will guide you through buying and selling a house, making the process effortless and smooth.

Saves Time

There are many things involved in the purchasing or selling of property, and it is time-consuming. It not only requires listing your property but identifying properties for sale, interviewing potential buyers, plus investigating, and inspecting properties. Julie and Monica handle these things on behalf of the buyer or seller. They research what needs to be repaired or installed before you buy or to increase your home value if you are selling.


REALTORS® know other REALTORS® or trusted individuals connected to the real estate market. These persons can be interior decorators, real estate lawyers, contractors, appraisers, or mortgage brokers and many others. Often, they will know another agent who’s looking for a specific property.  Monica and Julie have an extensive network which ensures access to information that will be valuable for the selling and buying of property.

Expert Negotiators

The demand for houses has increased, especially during the COVID-19 pandemic, with many people working remotely. The increase in demand has created a housing shortage and competition in the real estate market. Texas Property Sisters will effectively negotiate with potential buyers and sellers to get the best possible price. They will argue in your best interests and ensure that a deal is complete.


As REALTORS®, Julie and Monica are held to and must adhere to a higher standard of moral and ethical practices than real estate agents. They are required to follow a Code of Ethics related to the selling and buying of property and how to interact with the parties involved. This helps you as a buyer or sellor because you can be assured that they will always have your best interest at heart and will follow all laws as they relate to real estate transactions.

Monica and Julie will personally handle every aspect of your real estate transaction.  They never turn anything over to assistants or administrative clerks.  Using their knowledge of the local market and experience, they will guide you every step of the way.

Essentially, you get two Realtors® for the price of one!

The Texas Property Sisters (duo of Julie Williams and Monica Szewczyk) are THE BEST! We have worked with other realtors in the past but then we found Monica and Julie to work with on selling and buying our last homes. And wow, what a difference! They are so responsive and dependable/reliable... and willing to do whatever is possible to help you find/get what you want. They are also super energetic and friendly and easy to work with!

You can thank me later! 🙂

Great attitude. Excellent customer service. Selfless servant. These are just a few of things you get when working with Monica and Julie. I’m a lender and every deal we do together is so smooth. Monica works hard for her clients up front and makes sure her clients are getting the very best!!
Julie was an absolute pleasure to work with! I cannot say enough good things about her!A coworker recommended Julie & Monica. I called them and since then they didn't just help us find our dream home! But exceeded our expectation!We probably looked at over a 100 house, she was so patient with us and never pushed us to close on a house, sometimes my wife & I get too excited about a house that we miss the obvious problems with it (like street noise, walls cracks, etc.) but luckily we have Julie with us!She will tell us about any concerns about the house which really tells you that she cares about the people that are buying! Not just about making a sale.This was so important to us as It's not easy to find a realtor that you can trust!Julie makes the process so easy! We call her every time we have a list of houses that we want to see, sometimes she will have a list for us! She has excellent knowledge of the local market!Thank you so much Julie for being so patient with us, for answering all of our questions and being available whenever we needed you!Highly recommend and I look forward to working with Julie again in the future!
Response from the owner: It was our pleasure - you all were a delight to work with and so excited that you found your new home!
We have had the opportunity to work with Monica and Julie on multiple properties. They really know how to present their listings to capture the fullest potential for their home sellers. We look forward to continuing working with them!
Response from the owner: Thanks so much!
Monica & Julie (Texas Property Sisters) always provide an exceptional realtor experience. Both are extremely dedicated to meeting client's needs from start to finish. So refreshing to work with a team that is truly interested in the client's preferences and devoted to making those choices their priority - regardless how big or small those needs are.

Highly recommend them for any and all real estate services!

Monica is awesome. She has a top level of professionalism. I highly recommend her company!
Response from the owner: Thanks so much!
Such great people!!! I felt so comfortable throughout the entire process
Response from the owner: Thank you!!
Julie and Monica are truly a dream team. I’ve worked with realtors in the past who seemed to have their own agenda and not really listen to what I was looking for. That’s absolutely not the case here. I felt really supported through the entire process especially when things got a bit complicated and stressful, which they can so often when making such a large purchase. I highly recommend the Property Sisters to anyone who will listen!
Response from the owner: Thanks Annie - we loved working for you and with you!
I just worked a deal with Julie and Monica. They are professional, nice, and always kept me updated. As an agent myself it is great to come across agents like Julie and Monica. I look forward to working many deals with The Texas Property Sisters.
We were second time home buyers but first time in the US and Julie Williams was introduced to us by my husband’s secretary . She is very professional and at the same time a very good listener and patient person ! She went above and beyond in her customer service and helped us buy our first home here ! Our relationship didn’t end there it’s been over five years now and even how anything happens to our home we call/ text her and she sends us her contacts using her resources to fix the problem . That goes on to show the kind of person she is and that is the essence we believe that helps a person succeed in life and profession ! A zeal to connect with people and help them while being professional at the same time ! I will always approach her for any purchase/ sale I make in Dallas ! And I would highly recommend Texas Property Sisters every time !!Best wishesAnindita Sen Chowdhury
Response from the owner: Thanks Anindita you all were a joy to work for.
From start to finish Julie and Monica were amazing! As a first time home buyer I had a lot of questions and anxiety about the whole process, never once was I made to feel like an annoyance. There is no one I trust more with such an important purchase than the Texas Property Sisters!
Response from the owner: Thanks Kelsey - we loved working with you and love your new home!
Julie and Monica are consummate professionals when it comes to business owners. From providing guidance to buy or sell your home to their unwavering support of local charities, these two get it done!
Response from the owner: You are the best!
Had a great experience with Tiffanie in the sale of my first renovation project! She is straight to the point, organized and easy to talk to. I'm really looking forward to working with her and her sister on all of my projects!
I would highly recommend Julie and Monica. The service they offer goes above and beyond just selling your home. For personal references, please don’t hesitate to ask for my contact details from Julie.
knowledgeable ladies, understand the market, the area, and have the ability to match customer needs with the right property
Nice people who will always find you the best home!! Definitely recommend!
Great duo. Get the job done, personal touch and always there when you need them. Always arrive with a smile. I have had excellent experience both as a seller and a buyer.
