I've looked at all these reviews and there was one where someone said she is a "pit bull with…read morelipstick" and, honestly, that sums her up. Marianne is so knowledgeable, hardworking, and will fight to the end of the earth for her clients. She also deeply cares for the people she represents. I know she's working in my best interest always. She handled the sale of my mom's home that was within a trust, out of the area, and filled with two generations of stuff. I was an emotional wreck and she came in and guided me through it all. We got over asking, all cash deal within 10 days of going to market. Above and beyond work every day -- from clean up, to prep, to staging, to marketing, to negotiating. I'm just so fortunate to have had Marianne represent me. I can't emphasize enough how hard the whole selling decision was for me. She was patient, we explored various options together. When we ultimately decided the right decision was to sell, she sprang into action and got it done quickly so I could move on from a heartbreaking situation. Her style is uniquely hers. There's no bullshit. Marianne is going to tell it to you straight, but I personally wouldn't want it any other way. I can't say enough great things about Marianne!!! Hire her; you won't regret it.

My husband and I are first time landlords and despite not having a background in real estate, we…read moretried to manage our property ourselves. Everything was fine until the tenant stopped paying, and anyone who has dealt with these issues knows how stressful it can be. Lost and extremely frustrated, I called Marianne after doing some research on Yelp. Marianne was completely calm, confident, and professional. She quickly gathered basic information about us, the property, and the tenant. She informed us that she will be taking over and assured us that we will regain possession of the property. By that evening she had already sent over all the necessary DocuSign's and within the next couple days she was negotiating with the tenant on our behalf. Removing tenants for non-payment is devastating for both parties, so Marianne was firm, but also kind and compassionate. She was able to repossess the home within 15 days, without having to go through the process of an eviction, which was our goal from the beginning. Communication was always very quick, clear, and concise. My husband and I had so many questions since it was our first time going through something like this. She has a very extensive knowledge of real estate, the laws involved, and in general how tenants tend to behave, but she was also very patient and thorough when advising us. As someone that runs her own business and manages 100+ properties, Marianne is obviously a very busy person. I expected her staff to communicate with us after the tenant vacated the property. However, Marianne was our point of contact the entire time, which was very impressive. Marianne did not collect a penny from us during the entire tenant removal process, which really speaks to her confidence in her abilities as a property manager and her generosity as well. She is also well connected in the real estate space as all the references she provided to prepare the property for the next tenant were excellent. Our home was on the market for less than 2 weeks when she presented 2 solid potential tenants. Given how smoothly everything went up until this point, we were completely confident in letting her decide which tenant would suit us best. When we finally got to meet her in person, she told us that she takes care of all her properties like they are her own and after witnessing her work, it's clear that the service she provides is a direct reflection of her genuine passion for real estate and helping people. If you are looking to rent out your property, we absolutely recommend working with a property management group, but specifically, Marianne. Thank you Marianne. We appreciate everything that you have done for us, and we look forward to working with you for a long time!

I was a little worried at first about spending money on property management, but after how easy and smooth everything went, and how helpful and friendly the team is, I'm glad I found SUM Property Management and will definitely be using them for a good long while.

Shout out specifically to Stacy for answering all my questions from the start, making my life easier, and being available via email and text. She's super patient and makes sure any issues or problems are dealt, chasing down answers when she's not sure about something. Truly appreciate the service she and the team provides.

If you have a rental property in Brentwood, do not use this company. The owner, John Fink, has…read moremoved to Auburn and is rarely available to show your property. His handyman is highly incompetent and charges high prices for shoddy or incomplete work. John overpriced my rental resulting in a delay in getting a new tenant, refused to obtain proof of all income and told me the previous tenant left the place "immaculate". Even though professional cleaning of the windows and carpets is required in the contract, he didn't require the vacating tenant to complete these items. I've spend over $700 to replace screens, wash the windows, replace blinds and other items that should have been paid for by the tenant. Beware, this company does what's easiest for them, not what's best for their client. I've had this Property Management Company for 6 years and they started off doing a decent job but have really gone downhill in the last year or so.

We must have looked at over 30 houses together and I never felt any pressure to make a decision or felt that John was frustrated with how picky I was. What I enjoyed most about working with John was his knowledge of the area. He really looked out for my entire family - helping us choose the right school district and a great neighborhood. There were a few houses that I considered that would have been a mistake and John was confident enough to be firm in his opinions and guide me into making the right decision. Not only was John a great real estate agent, but he has also become a family friend. When our moving truck was delayed he showed up with a few boxes of necessities including pots and pans, blow-up mattresses, and linens. That really helped us through not a tough time. Thanks John! If you are looking for a new home or considering selling your current home you will not find a better option than John Fink.

My friends and I have listed and sold 4 homes through Mount Diablo Realty and Property Management…read more Raquel and Jon are an amazing team. When selling a home, the seller is faced with a multitude of issues- Pricing, asking the right price to get it sold takes market knowledge- Raquel and Jon have it nailed down. Before it's listed the property condition has to be assessed. Almost every house and yard will require repairs and/or up dating. Because they are experts in property management they have access to trade people like, plumbers, electricians. carpenters, painters, gardeners and sprinkler repair specialist. These trade people have worked for Raquel and Jon and have proven themselves to provide quality works at a reasonable price. Without Raquel and Jon working for you, you'll not only be searching for trade people to give you a bid, you'll have to deal with scheduling, pricing and access. Most of us don't have the time nor expertise to manage the day to day project management necessary to get the work preformed competently, on time and affordable. All this needs to be done before the for sale sign goes up! Raquel and Jon manage these tasks daily. If you want to sell your property without all the headaches of getting it ready to sell, select Mount Diablo Realty and Property Management.

CIMS has been our HOA management company for over 10 years. As a board member, I have worked…read moredirectly with several community managers and also have had some additional interactions with both the service managers and the upper management. In general, they check the boxes that need to be checked. They act as a liaison to vendors and homeowners. But over the last decade, they have gone from a involved problem solver, to a complacent, slow, and uncooperative company. After trying to raise concerns to upper management in 2022, we were assured our myriad of issues would be addressed and resolved. It helped for a couple of years, until our manager left for a better company. At the same time, our pricing continued to go up and we started getting charged for more items, and started being warned that certain items which used to be included in our management fee, would no longer be provided or would be add on services. Somewhere along the way, it was brought to my attention that Associa was now an owner of CIMS. This made sense... we suddenly had new service associates and backend teams responding to our owner requests... frequently with wrong information or resolving cases that were not resolved. In several cases, a vendor would say "this is completed", and they marked the work as complete without reviewing the work done or reaching out to the homeowner. Worst thing for a board member is hearing from a resident that said "4 months ago I created a service ticket. I was told it would be sent to the board for approval, then I never heard another word" despite the board approving the work, and there being a complete dropped ball by management. How do they correct these issues? They re-submit a new work request, do not apologize to the homeowner (making the board look even worse), not notifying the homeowner of the new work, and getting charged at times TWICE for the same repair work (which was never done in the first place). In 2025, our board brought up several items of concern to upper management, including several issues like service turnaround times, lack of information accessible in Vantaca (such as homeowner feedback or questions), and their inability to accept payment for ARC requests (or track them in Vantaca). What were we met with? Hostility, non-cooperation, and defensive deflections. Not a single issue was even addressed or apologized for... just fought back with excuses and combative rhetoric. When we finally decided to leave CIMS, they called the board, bad-mouthed their past employees, bad-mouthed our future management company, and were completely unprofessional in the way they went about trying to keep our business. CIMS was a great management company. It stinks that we had to leave them.... but so glad we did. They no longer go to bat for their associations, no longer do proper walkthroughs, no longer are on top of service requests, and are at least 25% more expensive than the other companies we considered.
