Potential Income

Adding Value to Your Home: Very few people are aware of the added value an ADU can bring to their property. As an example: the appraisal can be as high as 1 to 3 times the cost of the ADU and that value is added to the value of the existing home. Another reason is the high rental income in California. In fact, the number one reason people are building ADU’s is to live in the ADU and rent out their main home.

Lot Splits Can Bring Value and Income to Your Property:
Besides rental income and increased property value Senate Bill 9 allows for lot splits where you can now have up to 4 units after the Lot split. We are expert developers and can advise you correctly if this is proper for you and your financial goals. Give us a call and we will be glad to assist you.

Meet our fantastic leaders:

Gary Massari

CEO of REI (Real Estate Investments) Homes and ADU’s

Gary started his real estate career working with Falender Properties, a local real estate developer who subdivided land and sold finished lots to custom home builders. Gary would find the land, work with Falender properties to subdivide it into finished lots and sell the lots to builders. He would then help them design and build their homes based on current trends, then sell them to homebuyers, the builders were thrilled as they were getting top dollar for their homes. Soon Gary with his design skills, started building custom homes for his clients and joint venturing with contractors. This experience gave Gary the knowledge to work with clients and understand their dreams.

Today Gary turned his real estate experience into building award winning luxury homes in the San Francisco Bay Area setting the market price with his signature features, such as, Open Airy Floor Plans, Island Gourmet Kitchens, Veranda’s with 20-foot sliding doors opening to outside kitchens fireplaces, and heaters and fans for year around enjoyment.

Gary saw a huge need in the market for affordable housing and with the new senate bills allowing for additional dwellings, he added a stunning beautiful line of Farmhouse and Craftsmen design ADU’s. He wanted to bring his luxury home designs with his signature features to the ADU market offering luxury ADU’s at affordable prices. Gary knew that energy efficient homes coupled with WIFI smart homes would make his ADU’s cost effective when it came to utility bills. But he didn’t stop there, as he sees the advent of ambient lighting to change the environment by changing the color theme of the home – by simply saying “Fall” or program an app, certain rooms would display orange and yellow lighting, etc.

His motto is, “Tell us your dream and we will make it your dream home.”

Leweva Massari

Co-owner, & Acquisitions and Design Officer

Leweva started her career as a loan processor and then starting building mortgage companies with her husband, Gary. Both Gary and Leweva, were managing partners in Diablo Funding Group, with over 58 branches and 1200 loan officers. Leweva was one of the company’s top trainers. She was running the companies while Gary was busy marketing them.

Gary and Leweva also worked with builders and developers to subdivide land and build Luxury spec homes. Leweva encouraged Gary to return to real estate to do Fix and Flips, however, because building companies were in their blood, Leweva motivated Gary to build another company, this time building luxury homes, thus REI Fortunes, LLC was born. Leweva had a tack for design and would work with top designers to develop a design plan for their luxury homes, soon they built a reputation on building luxury stunning homes that would sell for top dollar quickly with multiple offers.

Leweva priced out the homes they would buy and gave estimates to their ARV (after repair value), and became so good at it, that all their homes became successful. She is now in charge of acquisitions and only with her approval does the company buy homes.

Leweva helps Gary and their partners with current trends and designs and is fully engaged in home design and interior design, especially for our new ADU line.
