Real Mortgage Case Studies from Southern California Buyers

Buying a home looks different for every buyer.

Over the years, I’ve helped first-time buyers, homeowners, and investors across Southern California use the right loan programs at the right stage. These case studies show how real people used down payment assistance, FHA and conventional loans, equity growth, and refinancing to reach their goals over time.

Each story below highlights the strategy used, the loan programs involved, and why the approach worked.

Case Study: How a Single Mother Used Down Payment Assistance and Equity to Buy Her Dream Home in Cerritos.

"Tanya” is a single mother in Southern California who wanted long-term stability for her family but did not have a large down payment saved when she started. Her goal was not just to buy a home, but to eventually move into a strong school district and create long-term options for her family.

Tanya bought her first condo in Carson using the CalHFA down payment assistance program. Her total out-of-pocket cost to buy the home was about $3,200.

This was not meant to be her forever home. It was a strategic first step to enter the market and begin building equity.

After several years, Tanya sold the condo and rolled the equity into a conventional loan for a home in Long Beach with 15 percent down.

About one year later, her loan balance reached roughly 78 percent loan-to-value. At that point, the mortgage insurance was removed and her monthly payment dropped by about $165.

With additional equity, Tanya sold the Long Beach home and bought a house in Lakewood, continuing to build long-term stability.

Roughly 15 years after her first purchase, Tanya moved into her dream home in Cerritos, located in the ABC Unified School District.

Case Study: How a Buyer Used Down Payment Assistance and Discipline to Become Mortgage-Free in La Puente

"Ismael” bought his home in La Puente with a clear long-term goal: become a homeowner and eventually eliminate his mortgage completely.

He did not start with a large amount of savings, but once he bought, he stayed disciplined and focused on paying the loan down as aggressively as possible.

In 2005, Ismael bought his home using a California state down payment assistance program that helped cover most of the down payment and closing costs. At the time, his total out-of-pocket cost was under $5,000.

That specific program no longer exists today, but similar options are still available through programs such as the Golden State Finance Authority (GSFA) and CalHFA, which work in nearly the same way.

Paydown strategy after purchase

From day one, Ismael treated the mortgage like a debt he wanted gone. He made bi-weekly payments instead of monthly payments. Every tax refund, bonus check, and extra income was applied directly to the principal balance.

In 2010, Ismael refinanced into a 15-year mortgage. This reduced the total interest he would pay over time and aligned with his goal of becoming debt-free. He continued the same aggressive paydown strategy after refinancing.

Mortgage-free by 2017

By 2017, Ismael made his final mortgage payment. Today, he owns his home outright and lives mortgage-free.

Case Study: How One Buyer Used FHA and Conventional Loans to Build a Multi-Property Portfolio and Buy a Dream Home in Glendora

“Jack” started as a first-time buyer who was open to living in imperfect properties if it meant long-term opportunity. His goal was not just homeownership, but to use real estate strategically over time.

Jack’s first purchase was a two-unit property in 2005 that needed work. He used an FHA 203k renovation loan, which allowed him to finance both the purchase and the repairs in one loan. The renovation funds were used to replace flooring and remodel the bathrooms. He lived in the property as his primary residence to qualify for FHA financing.

After the renovations were complete and the value improved, Jack refinanced into a conventional loan. This removed mortgage insurance and lowered his monthly payment. He lived in the property for a couple more years before converting it into a rental.

In 2009, Jack bought a triplex in Los Angeles using a standard FHA loan with 3.5 percent down. FHA allows purchases of up to four units with minimal down payment as long as the buyer occupies one unit. Jack lived in the property for three years to meet occupancy requirements.

After satisfying occupancy rules, Jack bought his first full investment property in 2012. This was a four-unit property in Long Beach purchased with a conventional loan and 25 percent down.

At this stage, his rental portfolio began supporting itself.

As his portfolio expanded, Jack bought a new primary residence in Covina in 2015 using a conventional loan with 10 percent down. Because it was his primary residence, conventional guidelines allowed a lower down payment than would be required for an investment property.

In 2022, Jack purchased his dream home in Glendora for $2.2 million. By this point, his rental properties were producing approximately $24,000 per month in cash flow, allowing his investments to do most of the work.
