Outstanding experience Outstanding experience Matt is dedicated to his craft and it shows through the level of communication and professionalism. I just closed my construction loan and Matt did a wonderful job keeping me updated with regular emails (many) years before the process started. He truly earned my business, giving me a great menu of products in combination with highly competitive rates. Moreover when there were other banking needs, he made very thoughtful introductions to help build a financial gameplan for years beyond the loan. The team and Matt have been exceptional in arranging a construction loan for my dream home. I am a busy professional working 6-6 on weekdays. They have accommodated my tight schedule and have met with me on weekends, evenings, and even on holidays. Through this entire process Matt and his team have been very responsive, building a long lasting relationship. Although the paperwork requirements were extensive we never doubted his ability to deliver. Matt very patiently guided me through all the requirements and couldn't have done it without him.

Diligent hard working and effective Diligent hard working and effective Matt and his team worked on a fast timeline, and got me a mortgage under non W-2 circumstances which less motivated brokers would just not touch. Throughout the entire process he was on top of email, requests, communication - always clear, punctual and effective. I highly recommend working with him, you will be happy throughout, and secure in the final result.

Matt understood my small business - and that was the key to our home mortgage Matt understood my small business - and that was the key to our home mortgage We were under contract to close on our new house, and we had to find a mortgage before selling our old home. Matt made it happen. The timing was a major challenge. And our financial situation was challenging to understand. My small business was successful, but it underwent significant changes last year that made the financial statements pretty complicated. I'm not sure that any other bank would have a loan office like Matt Siket, who was willing to take the time to get his head around it, and really see the bottom line. We got credit for our small business success at US Bank. At other banks, it seemed we weren't worth their time. Matt managed the process very closely. He was always available to give clear explanations of the loan review process and to make sure we got our documentation prepared correctly and submitted on time. Our new home has been life changing, and I don't think we would be here were it not for Matt and US bank. We are very grateful!

Best Banking Experience Ever Best Banking Experience Ever Matt was referred to me by the real estate broker handling the sale and it was the best referral I have ever received. My financial situation is complicated as I am retired with multiple sources of investment income. Matt sifted through the information provided and understood my situation. Matt created a mortgage loan package to perfectly fit the needs of my wife and I and made the process easy and efficient. Matt is the best banker/mortgage person I have ever worked with and highly recommend his services. Matt is attentive, professional and competent in making the loan process quick and easy for the borrower. There was not a single thing that I would have changed in the process from application to funding, the experience was 100% better than I had anticipated it being. Matt is simply the best.

Look no further - Matt is the best mortgage banker you will find. Look no further - Matt is the best mortgage banker you will find. After being strung along for months by my bank of 30 years they denied my loan refusing to accept income from a large investment portfolio for qualification. I was referred to a Matt and the process was totally different as he reengineered the loan package with his team and had me approved within a few weeks. On top of that he is efficient, follows up consistently and does not leave a stone unturned until you are funded. His enthusiasm for the process and his customers is beyond what I have ever experienced with a banker. He was available during weekends and evenings even to take or return a call. A rare gem in the world of finance.

Best loan officer I ever worked with Best loan officer I ever worked with My wife and I were going to build a house and need a construction loan, the designer/builder was qualified with US Bank so we contacted Matthew at U.S. Bank. Well Matthew was superb in getting everything together the designer/builder not so much. We had to get another builder and Matthew had to get the new builder qualified and everything we did before was rolled over from the first go at the loan. He stepped the builder and us through all the many steps to get the loan. He was there for us night, day and weekends for information, answering questions and helping with all the steps a construction has. I would give Matt the highest recommendation in the world without him we wouldn't have got financing.

Five Star and A+ Professional Five Star and A+ Professional My association with Matthew is extensive and dates back more than a decade. He has helped me in the past with corporate relocations to multiple states and finally as a retiree in Texas. My best and most recent experience involved buying a new home while transitioning into retirement. The fact that I was soon going to be a non-salaried individual made getting a loan with attractive terms challenging. Some lenders suggested that I just pay cash or make early withdrawals from retirement funds because it was too risky. Neither was an option for us. Further, we planned this move well in advance and just needed to work with a lender that understood that ours was not a risky case. Matthew clearly understood our situation, worked with his bank, and was able to quickly procure a loan that satisfied us. Additionally, I believe his rates and fees were as competitive if not better than other lenders we considered. Matthew did an outstanding job. His passion for his job, friendly demeanor, commitment to customer care, and response time were exemplary. It was a pleasure working with Matthew multiple times. I recommend him highly.

Awesome Broker/Lender Awesome Broker/Lender My wife and I are healthcare professionals that moved to Arizona from another state in 2018. Because of our move to a new state with new jobs waiting for us, the other bank we trusted let us down at the absolute last second. Their excuse was "no history of income in the state of Arizona", even though we have the financial means of purchasing a home with near perfect credit. The only thing we did not have was the experience of buying our first home. We showed proof that the income would come upon starting our new jobs and also offered to double our down payment, but they did not care and had no understanding. The bank we used before supposedly dealt with and was experienced with healthcare professionals, but showed their true colors when it came to us. We were then referred to Matt, who right away went to work for us. He understood our situation and really went the extra mile to ensure we would get our first house. Matt's communication throughout the entire process was invaluable as the previous bank's communication was almost non existent. Matt made the entire home buying experience a bit refreshing since he knew how rough it was on us the first time through. I can't recommend him enough as he truly stood by his word when he told us his experience with healthcare professionals and their sometimes complex cases. Do not hesitate to use Matt. Outstanding job and sticking with us through an already rough experience we were going through. Thanks so much Matt!

A+ Mortgage Officer! A+ Mortgage Officer! I was referred to Matthew Siket for help securing a mortgage when my bank and some other independent brokers were unable to provide mortgage financing. Due to the current lending climate, even though I had the assets to support the loan, it was difficult to meet the big box bank standards. I am a self employed business owner. US Bank and Matt recognized the value of winning my business and creating a relationship. They were easy to work with, offered competitive rates, and a seamless process. Matt consistently went to bat for me throughout the deal. I would highly recommend Matt, he was professional, efficient, and responsive.

Mortgage by Matthew

Helping You Buy, Borrow & Build Since 2001

For more than two decades, I’ve helped clients turn real estate goals into results. I’ve worked inside both small brokerages and large banks and learned what each does best. The ideal lending experience sits between the two: flexibility, resources, and personal attention in equal measure.

That balance is why I partnered with Liberty Federal Credit Union. We pair strong leadership and a broad program menu with a clear, client-first approach. You get options that outperform most large institutions and the service you expect from a boutique lender—backed by competitive pricing and transparent fees.

The mortgage process can be complex, but your lender shouldn’t make it harder. My role is to bring clarity, set expectations, and keep your file moving—whether you’re buying your first home, building your forever home, or relocating across the country.

Bring your questions. The more context I have, the better I can tailor your plan. My goal is simple: you should feel fully informed and confident before choosing a loan structure that supports your future.
