Testimonials
"
We worked with William and Ann to sell our commercial property and business in a rural part of Nevada. Although they were unfamiliar with the area they agreed to handle the listing. This was in March 2020 just as everything was going into lockdown. However, they pressed forward and a couple of buyers expressed interest in the property. William and Ann truly advocated for us. Despite numerous unforeseen roadblocks, they were able to provide options and solutions, run interference, and close the sale even during the COVID shutdown. We could not have done this without Ann and William.

Anne was an absolute joy to work with and made the entire process very easy with great communication throughout! I can't recommend the entire Mariani group enough. We got a higher price for our house than I was expecting and the sale closed much faster than I anticipated.

William did the best job possible selling my house in Reno. He was always totally aware of timing concerns and my peace of mind. These things are rarely completely smooth, but William does everything he can to make them as smooth as possible, at the same time as getting the best possible price for your property. He has all the skill and experience to do this. Thanks William. You’re the best!

William is absolutely amazing. I can't say enough positive things about him. He is super invested in his career and you. He always has so much positive energy and is absolutely someone you can trust in your corner. Hands down, you can't find someone better!

William and his team did an outstanding job in selling my home. His attention to detail and willingness to go above and beyond was a tremendous benefit during this stressful time. His market sense was phenomenal and had my house positioned perfectly so that I was to sell it within a week of listing on the MLS. I highly recommend William and NextHome Realty!

William Mariani was not only a pleasure to work with, but was also an excellent professional. He helped my family and I sell our mother's home after her death and showed us compassion as we made difficult decisions. I have sold several homes, so I was impressed with his knowledge of comparable homes in our market and how best to price this house despite a declining market. As we closed this deal, he demonstrated great patience and diplomacy in dealing with demanding buyers and last minute clean outs. Ultimately, he got us the price we wanted in a timely manner. I highly recommend his real estate services.

William and his team went above and beyond to help us into our new home. My husband and I can’t express enough how grateful we are for their hard work. Our new home had quite a few “extra hoops” to jump through, but that didn’t deter or slow down the team. 12/10 recommendation from the Anderson’s!

Having sold multiple residential properties across the country, Mariani Residential Group are the best realtors we have ever used.
William, Anne and their associates have always been cooperative, holding multiple open houses, investigating market conditions, working to come up with creative ideas including virtual staging of an empty home with enlarged photos of what rooms could look like on display, and preferred mortgage options during a very difficult market. They do not know the word “NO” and were always willing to go beyond the call of duty to get your property sold at a price that will make you smile.
Simply the best!

I trusted William and Anne to find my son his first home. Immediately they plugged us into new listings so we could act quickly. Every new listing we received a text. They toured us through about a dozen homes until my son and I found the perfect home. They managed the offer well, quickly set up quality inspections and helped get minor repairs taken care of quickly. I highly recommend William Mariani, Anne Potter and his team at Next Home!

We would highly recommend William Mariani and his team of professionals to help you sell your home as well as find your next dream home. From our very first meeting with William and his team, we felt they had a very good understanding of what we were looking for in our next home. Once we found the home we loved, William went to work to get our offer accepted in a market where multiple bids were taking place. We felt our best interests were always at the forefront during the entire buying process, from finding the home to closing escrow. We can't thank William and his team enough for all their help in making our dream come true!

During 2022 we were pressed to move, William and his teammate Anne did a fantastic job at finding us a Realtor in our location who was the perfect fit for us. They continued to make sure along the way and through the process of us selling that we were happy with the choice they made for us and were there if we needed them!

Michael and his team were absolutely amazing, from the very beginning to the very end. Starting off at finding the right homes to show me based off of my requirements, in order to not waste my time, all the way to finding custom glass doors that would make my new home complete. I had complete peace of mind throughout the entire process.
There is no better realtor in the area!

I cannot more strongly recommend WIlliam Mariani and crew to anyone looking to list a house. The Reno Real Estate Market does not function like other real estate markets and you need someone with experience that can navigate the challenges of the marketplace.
The service that William and crew gave me was exceptional. William had a network of people that were able to make minor repairs and do maintenance on my property. They also regularly checked on it as I had to vacate the house for a while before it sold.
The fruits of their excellence bore out with an inspection that yielded no issues, which is rare indeed. The Escrow closed quickly and efficiently (something like 22 days) because of William's expertise, his staff and the excellent professionals they used to work with on the sale of my house.
Lastly, the price we sold our home for was solid and the negotiation with the folks that bought our house was smooth and quick.
In every aspect of selling / buying a home (I have done both with William and crew) they excel.
