Most real estate investing beginners enter the market with ambitious, often overwhelming targets: aiming to accumulate portfolios of 10, 20, or even 50 rental properties across the country. But for Erik Caci, a medical device sales professional based in Los Angeles, the roadmap to financial freedom required a much more focused approach. Armed with strategic house hacking and a long-term buy-and-hold mindset, Caci believes that just two properly selected duplexes—totaling four rental units—will be more than enough to secure a comfortable retirement.
The journey began when a career transition forced Caci to relocate to Los Angeles, a housing market notorious for having some of the highest home prices and rental rates in the United States. Speaking on an episode of the Real Estate Rookie podcast hosted by Ashley Karr, Caci detailed his unorthodox path into real estate, which started long before he knew the industry well. Growing up, Caci worked in retail sales during high school and college, eventually breaking into luxury retail with Louis Vuitton. That early experience refined his skills in client development and relationship management before he transitioned into a fixed-income medical device sales role. Five years ago, his career brought him from the East Coast to Southern California, drastically changing his income structure and opening the door to larger investment strategies.
After building a stable W-2 income and listening to personal finance and real estate podcasts, Caci caught the investing bug. His first venture into property ownership was actually a condo in New Jersey near the New York City market, purchased before his relocation. Although he held onto it briefly, he eventually sold it as he transitioned across the country. That initial transaction served as a valuable, albeit minor, introduction to running numbers and navigating the purchasing process. Once established in Los Angeles, however, he realized that any viable investment strategy would have to rely heavily on house hacking to offset the steep cost of living.
Finding Opportunity in an Overlooked Los Angeles Property
Caci’s first major acquisition was a century-old duplex located in the Jefferson Park neighborhood of Los Angeles. Built in 1924, the property had languished on Zillow for more than 90 days, enduring multiple price drops while other prospective buyers passed it by. For Caci, the long days on the market signaled an opportunity. Zillow alerts kept the property on his radar screen, and its appealing architectural bones and location in an up-and-coming neighborhood drew him in.
The property was located within a Historic Preservation Overlay Zone (HPOZ). For many real estate investors, historic districts represent a massive deterrent due to strict regulations overseen by local preservation committees. Caci, however, viewed the restriction as a positive indicator. The HPOZ rules meant that the architectural integrity of the 1920s bungalows would be protected from speculative high-rise development, preserving the neighborhood’s unique character. Furthermore, he noted that the adjacent West Adams neighborhood had experienced the highest property value growth of any area in Los Angeles between 2016 and 2024. Recognizing Jefferson Park as a sister neighborhood primed for similar gentrification, Caci felt confident moving forward.
Navigating the historic preservation guidelines proved far less daunting than anticipated. Because he intended to restore the property rather than alter its core architecture, securing approvals for items like windows, exterior paint colors, and roofing materials from the local committee went smoothly.
Overcoming Renovation Hurdles and Securing Vacant Delivery
To successfully house hack the duplex, Caci faced a significant hurdle: the property was fully occupied, and he needed at least one unit delivered vacant upon closing. Unfamiliar with standard real estate protocols but well-versed in sales negotiation, Caci simply asked the seller to deliver a vacant unit as a condition of his offer. Given that the property had sat on the market for over three months, the seller was motivated to offload it. To expedite the process, the seller utilized a standard Los Angeles practice known as "cash for keys," paying a departing tenant between $20,000 and $25,000 to vacate the premises within a strict 45-day escrow timeline.
Financially, Caci initially considered putting down 5% to 10%, but inspections revealed that the property required extensive work, including a new sewer line and roof repairs. Opting for an FHA loan, he put down just 3.5%, amounting to a little over $23,000, alongside roughly $5,000 in closing costs. After credits and splitting certain sewer and foundation repair costs with the seller, he was all-in for approximately $30,000 before renovations.
Once the previous tenant moved out and the purchase closed, the true condition of the unit became apparent. Stripped of furniture, the 650-square-foot, two-bedroom, one-bathroom unit was in rough shape, featuring worn walls, historic wear and tear, and mold in the bedroom ceiling. Caci hired a general contractor referred through local architectural connections to manage a $26,000 cosmetic and layout overhaul. Mold remediation added another $6,000 to the bill, bringing total renovation costs to around $40,000 to $45,000.
While mold often terrifies prospective buyers, Caci noted that treating it is a straightforward, albeit necessary, expense. By doing thorough research and leaning on his real estate agent and contractor network, he transformed a daunting repair into a manageable hurdle that ultimately discouraged competing buyers.
The Long-Term Wealth Strategy: Cash Flow Versus Appreciation
Following the renovation, Caci moved into the property with his partner and their dogs. The duplex featured a second unit occupied by long-term tenants who had lived there for over a decade, paying below-market rent of around $1,550 a month. With an FHA mortgage totaling roughly $5,000, Caci was initially covering a monthly deficit, as market rents for the unrenovated unit sat significantly higher.
Rather than chasing immediate cash flow, Caci structured his investment around a long-term buy-and-hold strategy. Relying on his stable W-2 income from medical device sales, he viewed the monthly shortfall not as a loss, but as a forced savings plan. While the tenant’s below-market rent covered a substantial portion of the monthly obligation, the property steadily built equity through mortgage paydown and benefited from the continuous appreciation inherent to the Los Angeles real estate market.
Buoyed by the success of his first project, Caci applied the lessons he learned to his second acquisition: a duplex in the heart of Hollywood. Seeking a location closer to the central hubs of West Hollywood and Beverly Hills, he targeted a property that offered stronger initial metrics and included valuable amenities like a driveway and a tandem garage with potential for future accessory use.
This time, Caci opted to put down 12% to lower his monthly debt service and bring the property closer to a break-even point. Across both properties, his total monthly mortgage obligations now sit at $9,600, while existing rental income brings in $5,800. While he currently covers a monthly deficit of about $3,800 out of pocket while living in one unit, upcoming renovations on his current side will soon allow him to rent it out, dropping his net personal housing cost down to a manageable fraction.
Expanding Horizons and Scaling the Portfolio
Caci’s disciplined approach challenges the conventional real estate advice of accumulating dozens of properties in Midwestern or Southern markets. For him, owning four high-quality units across two Los Angeles duplexes represents a secure foundation for retirement, projecting strong cash-flow potential once the mortgages are paid off over the next three decades.
However, recognizing the slower pace required to acquire high-priced Los Angeles real estate using personal capital, Caci has begun exploring new strategies to scale his portfolio. He has started looking into single-family BRRRR (Buy, Rehabilitate, Rent, Refinance, Repeat) deals in Midwestern markets such as Memphis, Tennessee, and Detroit, Michigan. To navigate this unfamiliar territory remotely, he enlisted the mentorship of experienced investors who operate successfully in those regions.
By maintaining his W-2 career as a financial safety net, carefully managing his cash reserves, and leveraging strategic house hacking, Caci has built a sustainable real estate portfolio designed to yield long-term financial independence without sacrificing peace of mind.
