Fantastic experience: We worked with Santi and Holly to get my Mom's Condo sold after her passing. They made to process as stress free as possible.

The entire team they worked with were very helpful in letting me know what documents I needed.

It’s rare to find a team that combines deep industry knowledge with such a personal and reassuring approach.

Fantastic experience: Always great experience working Melina and team.
Fantastic experience: I had an outstanding experience working with Root River Realty to sell my property. From the very beginning, their team demonstrated exceptional professionalism, expertise, and dedication to ensuring a smooth and successful process.
Fantastic experience: I've purchased and sold properties with these guys for a few year. Real estate has so many facets to it. Each is very important. They're are very knowledgeable and in touch with the market(s). Down to earth, very approachable and accessible. This is a great quality because these deals can get stressful. Last summer, Santi remained in contact with me, for a purchase deal, while overseas!! They've answered every call and text. (Even 5:30am!) I have no problem referring their company to anyone.
Fantastic experience: Holly, Santiago and team are great. Have worked with them a few years. As a novice investor their knowledge and expertise have lead me to some great deals!
Fantastic experience: Top team in SE WI!! Great with communication which is hard to find in this industry these days!
Fantastic experience: Holly & Santi are great to work with! We just had our first closing together on a challenging listing - they did an amazing job!
Fantastic experience: We had a great real estate experience with Santi and Holly! We were purchasing a house from out of state, and they went above and beyond to make sure everything went smoothly. Exceptionally nice and friendly people as well!
Fantastic experience: We recently purchased a condo in the Lakeshore Commons community with Santi and Holly Speranza of Root River Realty powered by KW, and the experience was nothing short of exceptional! Having spent 14 years in the real estate industry and collaborating with Holly on behalf of my clients in the past, I was thrilled to work with her and the team on a personal level. Their professionalism, extensive network, and tireless work ethic continue to impress me. The entire Root River Realty team made the process seamless and enjoyable—it was, hands down, the easiest real estate transaction I’ve ever experienced. I’m so grateful for their expertise and support in both buying and selling our condo!
Fantastic experience: I have just been so incredibly impressed with the level of service from this team. I popped into one of their developments to view a lot without an appointment. Santi was notified and was onsite to tour me within 30 minutes. By the end of that week, we had an approved offer (that Santi expertly assisted in negotiating for us) and Holly, Amanda, Crystal & team made sure we were able to be closed by the end of the month. I'm so excited to begin building my new home and can't thank this team enough for all they did to help close this deal. I'd recommend them to anyone!
Fantastic experience: Great people, professional... Truly a class act in real estate. Was a pleasure and look forward to many more transactions

Fantastic experience: Absolutely fantastic realtors and even better people! I can't recommend them hi gf my enough!
Fantastic experience: This was my first time purchasing a house and I had a great experience working with Santi and Holly. I appreciated their honesty and feed back during the whole process.

Fantastic experience: It’s been more than a pleasure working with Santiago, Holly and the Root River Realty team! Their work ethic is unmatched!

Fantastic experience: Professionalism at its finest, when you’re working with a Root River Realty agent- you can expect timely communication and a positive experience! I’ve done a couple deals with this business and have had the pleasure to get to know them, have always had the best time with them and am amazed at how they continue to persevere and thrive in this real estate market.
Fantastic experience: Santi and Holly from Root River Realty are the real deal. They got me out of a tough situation with my flip project gone wrong and did everything they said they would do for me and then some. They really stepped up and now they have a client for life in me and I'll be referring them to everyone that I know. Huge Kudos!
Fantastic experience: Root River Realty is who you want in your corner. They will fight for you to ensure you are getting a great deal. They are always available to provide updates and take much of the stress out of the process.
Thank you so much for the wonderful review! We appreciate you.
Fantastic experience: I couldn't have asked for a more exceptional team to help me sell my nine investment properties than Santi and Holly at Root River Realty. From our very first meeting to the successful closing of each property, they consistently demonstrated a level of expertise and dedication that was truly remarkable. Santi and Holly's knowledge of the real estate market is unparalleled. They provided me with in-depth market analysis, ensuring that I set competitive prices for my properties. They were proactive in identifying potential buyers and marketing my properties effectively, which resulted in quicker sales and better-than-expected returns on my investments. What truly stood out was their commitment to going above and beyond. They were always available to answer my questions and address any concerns. Their attention to detail in managing the entire sales process, from staging the properties to handling negotiations and paperwork, made the entire experience smooth and stress-free. I felt like I had a team of professionals who had my best interests at heart. Santi and Holly's communication skills were exceptional. They kept me informed at every step, providing regular updates and ensuring that I was well-informed about the progress of each property sale. This level of transparency and communication instilled a high degree of trust and confidence in their abilities. I have worked with real estate agents in the past, but Santi and Holly at Root River Realty are in a league of their own. They combine their market expertise, dedication, and professionalism to deliver results that far exceed expectations. I couldn't be happier with the outcomes they achieved for me. If you're looking for a real estate team that will not only meet your expectations but surpass them, I wholeheartedly recommend Santi and Holly at Root River Realty. Their commitment to excellence and their unwavering dedication to their clients make them the absolute best in the business. I'm grateful for their outstanding service and look forward to working with them again in the future. Thank you, Santi and Holly, for your exceptional work!
Fantastic experience: I am so impressed with Santiago and his professional help selling my investment property. As an out of state investor, I needed a team member who could help me deal with a difficult property manager to get the property sold. River Root Realty was the correct choice! Santiago understood what I needed, and used his network to help me with a quick and well-done bath remodel for a fraction of what the property manager would have charged. He was able to use his relationships with the property management company to get information and property access to keep the process moving. Never once, was I concerned he would drop the ball or forget details. I felt secure in knowing he was doing everything possible to get this property sold before the winter. His common sense advice, sense of humor and professionalism was the perfect fit. I will gladly refer him to others.
Fantastic experience: If you are looking for an above and beyond experience, Santi & Holly are it. I am moving a portfolio to chase the next & the EFFORT they give to provide the best value is unmatched. What you get with them that you won't with others are coordination with PMs (typically not a fun thing for anyone), coordination with tenants, aggressive but realistic pricing, and they have a massive buyers list! If you want a property moved stop looking and just reach out to them. They took care of me like family. One of the things overlooked when picking a realty company to go with is their marketing strategy, their interest for everyone to win, and the ability to be HONEST! If you look further after this post you're wasting your time. Just reach out to them and make it happen! As an investor speed and pricing is critical! Thats exactly what I got here.
Fantastic experience: I’ve worked with Root River Realty on a number of properties, for both buying and selling. Santi and Holly are an investor friendly group and willing to go the extra mile to make magic happen. I’m thankful for having worked with them and utilizing their experience and guidance through this market. If you need a realtor in Milwaukee, contact them!
Fantastic experience: Santiago, Holly and their team are very prompt, responsive, and professional. Santiago is very dedicated to getting the deal done no matter the time of day. We remember signing contracts late at night just to secure the deal. If you want a go getter team this is your team.
Fantastic experience: They are without a doubt the best realtors in the state. They've earned all of my business going forward.
Fantastic experience: Team of absolute rock stars! They truly understand what investors are looking from Their agents. Will definitely continue to work with Santi and team
Fantastic experience: Holly and Santi will go the extra mile to help you find what you are looking for!!!!
Fantastic experience: The best people that will take care of all your real estate needs!
Fantastic experience: Root River Realty is the best! The communications from all people at Root River was prompt with sage wisdom stemming from over a decade of excellent experience. The way they are caring and helpful to us as we invested in our new home was reassuring and professional. They take their work and clients very seriously and you can tell they are working hard for your vision and making the smoothest experience for you!!
Fantastic experience: Holly and Santi are a dynamic duo. They are knowledgeable, professional and always accessible. I have purchased and sold multiple properties with Root River Realty and each one went smoothly.
Fantastic experience: Truely the best experience I've had with a Real Estate company. Santi and Holly are amazing and I plan to use them in the future if we decide to sell our current home and purchase a new one.
Fantastic experience: Easy to work with, great at negotiating, superb attention to detail and wonderfully caring people!
Fantastic experience: Holly and team are world class and helped us through what we expected to be a long and grueling process. Thank you Root River Team.
Fantastic experience: Great people, very knowledgeable in the world of real estate.
Fantastic experience: Santi and Holly are the greatest! Professional, timely, and always helpful. Highly recommend!!
Fantastic experience: I have personally known and worked closely with Holly and Santiago over the past 18 months, and successfully closed on 20 investment properties valued in excess of $1M. They, along with the entire Root River Realty team are true professionals, providing outstanding service and support through all phases of these transactions—many of which were complex. As an out of state investor, they made my business partner and I feel comfortable right away and truly had our best interests at heart. We spent over six months building the relationship, getting to know the area, analyzing property types, neighborhoods, etc. They were always helpful in answering questions and provided sound advice and analysis of the portfolio we built together. We never felt pressured to make offers that did not fit our purchase criteria and felt they truly understood and met our requirements. Most importantly, Holly, Santi and the entire Root River team remained supportive and helpful well after the transactions closed, ensuring we had all of the tools and resources in place to succeed. This is a true testament to the high character and integrity of this brokerage and demonstrates genuine commitment and care towards their clients. Incidentally, I was shocked to see a negative review on here and do not believe the allegation this obviously disgruntled buyer made against Root River Realty. It is unfortunate that this person was unable to resolve whatever issue arose and chose to air their discontent through a negative review. In closing, I HIGHLY recommend Root River Realty for all of your real estate needs in the area! Take the time to get to know these outstanding professional and build a strong working relationship! I assure you the Root River team will go above and beyond to meet your goals! Thank you, Holly, Santiago and the entire Root River Realty Team!
Negative experience: Avoid them if you could. I was to buy 5 duplexes but thankfully ended up buying just one. Since I am an out of state investor I was told I would be given a post closing walk through. The moment I closed everyone just changed. The references they gave were even more unreliable. It's all sweet talk while they are waiting on you to close. They also shared numbers from my settlement statement to their property management company contact without my permission. Be glad I am not reporting them to real estate commission.
Fantastic experience: I had a wonderful experience working with Santi, Holly and Amanda Jo. They took great care of me from start to finish and I was in constant communication with them every step of the way. Highly recommended!
