As our company name implies, we are a "Cornerstone", a vital part of managing rental properties - a task that can be both time consuming and complicated.

    We provide each property owner with the greatest possible return on their investment. At the same time, we work to build long term relationships with property owners and residents alike. Our goals are simple, we strive to maximize income and minimize expenses and vacancies.

    One important role we offer is that of acting as liaison between the landlord and tenant. Property manager relations with Residents gives a face to the Landlord and provides them the necessary buffer servicing their desire to profit and distance themselves from their tenant constituency.

    Our duties include accepting rent, responding to and addressing maintenance issues, advertising vacancies for landlords, and doing credit and background checks on tenants. In exchange for the service we provide, we charge landlords a percentage of the gross rent collected each month, in addition to lease commissions and repair costs that may be marked up as we prepare the property for a new tenant.

    Cornerstone Property Management is proud to offer most complete and professional services available today. We are a full service property management company. We provide the services you need to make and keep your income property a success. Our main goal is to protect your investment and maximize the potential of that property.

    We are proud to say that we would manage your property as we would one of our own. Owners are always involved in all the decisions regarding maintenance, improvements and tenant issues. We would like to take away the burden of managing your own property, but not take away your control. As with any successful business we are dedicated to earning your trust and respect.

    We are available 24 hours a day for emergencies, and could be easily contacted for any other problems during and after our working hours. Owners have a choice of handling repairs themselves or using any of the contractors they choose, if they have no preference we can suggest many skillful and licensed contractors to handle all your maintenance needs.

  • Our Team


    Since 2000, I have sold hundreds of residential properties and luxury homes. When moving to Sacramento in 2001, I started purchasing several new homes as income properties and convinced many clients to follow suit. In 2004, my associate Zen Mendoza and I founded Cornerstone Property Management and Sales to help all of our real estate investors market and manage their income properties. When marketing a rental property, I make sure that the home shows its best through furniture rearrangements, cosmetic repairs and painting, and landscape clean-up and maintenance, and get the most marketing exposure through signage, open houses, web ads, color flyers, floor plans (if available) and various social media. The key to success in leasing the property quickly is how well the exterior and interior is presented and pricing at current rental market value. I give my honest opinion on the current condition of the property and give recommendations on what needs to be done to get the highest rent and leased quickly.

    Because I am also a Realtor and Broker of Cornerstone Real Estate Services (a subsidiary of Cornerstone Property Management), I give landlords professional advice when it is the right time to sell their income properties to capture their highest equity gain. In addition, I find and help purchase the best income properties for my current landlords and investors according to their budget.

  • Testimonials

    The Cornerstone Property Management team is highly professional and responsive. There were only two instances (in two years as a tenant) that I needed a maintenance call. Each time, the maintenance technician called me immediately to understand the problem, arrived within an hour, and made the necessary repairs. The management team then followed up with me to ensure my satisfaction with the solution - and I was the tenant, not the owner! Cornerstone treats its tenants and properties with the utmost respect.

    Mani Del Rosario and Cornerstone Property Management have managed a single family home rental property in in Natomas for me for over eight years. As a busy working mom, Cornerstone Property Management makes renting my home headache and hassle free. They take care of advertising the property, screening applicants, collecting rent, facilitating maintenance needs, securing cleaning and minor repair services in between tenants. My draw is deposited into my bank account and statements detailing income and expenses are emailed to me promptly each month. I appreciate the ease and convenience of being a landlord with the services Cornerstone provides!

    I've worked with Cornerstone on several projects over the past few years. Their team has provided a number of services to help out me and my family. I think they're very knowledgeable about Sacramento, they deliver solid advice, and they're rock solid reliable.

    ~Brian Tokuyoshi - Landlord

    Mani and the team at Cornerstone Property Management are first class. We have used them on three properties and referred others to them since 2011. We especially appreciate the high standards that Mani has in cleaning and turning over the properties.

    ~Kenrick Young - Landlord

    ~Jose and Gilda Leonardo - Landlords

    This is the best property management group I've ever worked with. If you are considering using this firm to manage your property or to rent from, feel free to reach out to me with any questions. They are very detail oriented and do an excellent job at resolving problems with the home quickly and efficiently. They are easy to work with and I highly recommend them.

    When renting from them as a tenant, they did an excellent job during our walk through at reviewing every detail - this seemed a bit cumbersome at the time but when we were preparing to vacate the property and they did the same level of review as we were moving out, it was all very fair - and we've worked with other property management groups who were terrible about this.

    ~Dennis Alby - Tenant

    I personally have rented from & bought from Mani in North Natomas. I've known him for six years and he is the most knowledgeable in this area hands down!! The Natomas Park area is what he specializes in, period. Mani is a forward going person who is sharp at what he does throughout his entire lifestyle. He is very active, outgoing, easy going, friendly and is a normal person with no drama. Period.

    As a tenant I can't thank him enough for taking care of me for four years on Macon drive. Mani is the reason why we decided to eventually buy in this area Right before the market turned around AND I love the private clubhouse too!!
