DALLAS, Texas — In late 2023, the American dream of homeownership looked increasingly out of reach for everyday buyers. With mortgage rates spiking to 7.5%, countless prospective homeowners were abruptly priced out of the housing market. For Andres Martinez, a former jazz musician turned full-time restaurant waiter, this financial roadblock could have easily been the end of the road. Instead, it served as the catalyst for an extraordinary career pivot that transformed him into one of the most innovative young real estate investors in the Dallas-Fort Worth metroplex.
Today, Martinez commands a sprawling portfolio comprising 14 properties (10 owned outright and four under management), housing an astonishing 107 individual co-living rooms. Generating approximately $27,000 in monthly gross portfolio cash flow—and pocketing a net passive income of $12,000 to $14,000 monthly while working just a couple of days a week—Martinez’s journey offers a masterclass in resilience, creative financing, and operational adaptability.
Main Facts: The Anatomy of a Modern Real Estate Portfolio
To understand Martinez’s success, one must look closely at the mechanics of his current operation. Operating primarily out of Dallas, Texas, Martinez has systematically dismantled traditional real estate investing models, replacing them with a hybrid approach tailored to today’s high-interest-rate environment.

Chronology: From the Restaurant Floor to Co-Living Dominance
Martinez’s ascent was far from an overnight success story. It was forged through grueling hours, relentless rejection, and hard-earned lessons on the front lines of construction and negotiation.
Phase 1: The Cold-Calling Grind and the First Wholesale Deal
When rising interest rates slammed the door on Martinez and his wife purchasing a traditional home, he refused to accept defeat. Plunging headfirst into the world of creative real estate education, Martinez identified a massive inefficiency in the market: sellers burdened by high interest rates or looming foreclosures who could not sell through conventional channels.
His weapon of choice? Cold-calling.
Working long shifts as a restaurant waiter, Martinez would slip away to dial Zillow listings relentlessly, making between 500 and 600 cold calls a day. He aggressively pitched concepts like "subject-to" financing (where an investor takes over the seller’s existing low-rate mortgage) and seller financing.
The strategy yielded his very first transaction—a wholesale assignment deal that netted him a modest $10,000 assignment fee. However, the victory was hard-won. His next deal required nine months of daily rejection, calling 250 to 300 people a day, and getting fired from his restaurant job twice for taking motivated-seller calls during service hours.
Just two weeks after he had psychologically given up, a previously unresponsive seller texted him back. The buyer originally under contract had failed to secure financing, and the seller was facing imminent default. Martinez stepped in, closed the deal, and secured his undeniable proof of concept.
Phase 2: Discovering Co-Living and Surviving Contractor Fraud
Intrigued by the concept of maximizing rental yields, Martinez turned his attention to co-living—the practice of renting out individual rooms within a single-family home to maximize gross income.
Through a local real estate meetup, he identified a distressed, pre-foreclosure five-bedroom, three-bathroom home that other investors had dismissed due to its complexity. Utilizing a subject-to structure, Martinez acquired the property with just $3,000 down, stepping into the seller’s existing mortgage obligations.
To make the property viable for co-living, however, it required substantial renovation: adding three additional bedrooms, replacing flooring, and fully furnishing the space, totaling an estimated $58,000 budget. A capital partner stepped in to fund the project in exchange for a 50/50 equity split, with Martinez managing the execution.
What followed was a nightmare scenario familiar to many real estate rookies: the hired general contractor stole renovation funds, left the work incomplete, and failed to pay the subcontractors. To salvage the project, Martinez was forced to pay roughly $40,000 out of pocket, rolling up his sleeves to install flooring and finish the manual labor himself.
Phase 3: Vertical Integration and Becoming the General Contractor
Rather than letting early setbacks derail his ambitions, Martinez weaponized the experience. When a nearly identical scenario played out on his second co-living project—an eight-bedroom house complete with an Accessory Dwelling Unit (ADU)—where the primary contractor disappeared, Martinez took decisive action.
He approached the abandoned crew leader and offered him steady, reliable employment in exchange for a crash course in construction trades: tile work, drywall installation, and flooring.
By eliminating the middleman, Martinez became his own general contractor. This vertical integration revolutionized his business timeline. Renovations that previously dragged on for six to eight weeks under external contractors were slashed to just two weeks, as Martinez kept a dedicated crew moving efficiently through a single pipeline.
This operational mastery organically expanded into a separate, highly lucrative business line. Today, Martinez has personally acted as the general contractor for 29 co-living conversions belonging to other real estate investors, significantly diversifying his income streams.
Supporting Data: The Economics of Co-Living
To appreciate why Martinez pivoted so aggressively away from standard single-family rentals, one must examine the raw financial metrics of his co-living model.
Taking his inaugural conversion property as a case study:
- Acquisition Structure: Subject-to existing mortgage, $3,000 down payment.
- Monthly Carrying Costs: $2,100 total covering the existing mortgage, property taxes, and hazard insurance.
- Rental Structure: Four standard private rooms rented at $800 to $850 per month, plus one premium master suite featuring a private bathroom rented at $1,000 per month.
- Gross Monthly Revenue: Approximately $6,500.
- Net Monthly Cash Flow: $2,700 to $2,800 from a single residential property.
By comparison, a traditional long-term rental of the same property might command a gross monthly rent of $2,200 to $2,400, leaving razor-thin margins after debt service and maintenance. Martinez’s room-by-room model nearly triples the revenue generated from the exact same physical footprint.
Addressing Industry Misconceptions: Myths vs. Reality
As co-living gains traction as an emerging asset class—frequently positioned as a sustainable alternative to the increasingly regulated short-term rental (Airbnb) market—industry observers often raise concerns regarding management intensity and tenant friction. Martinez is quick to challenge these assumptions.
Myth 1: Co-Living Is Unstable and High-Turnover
- The Reality: Critics assume renting to multiple individuals under one roof leads to constant tenant disputes and high vacancy rates. Martinez combats this by carefully curating his tenant demographic. He targets working-class adults who earn stable incomes but are priced out of standalone apartments in the competitive Dallas market. Furthermore, he utilizes month-to-month leases initially, allowing either party a clean exit before locking into a 12-month commitment. Once a house establishes a cohesive culture, turnover drops dramatically. Martinez notes that tenants from his very first co-living property continue to renew their leases year after year.
Myth 2: Co-Living Conversions Destroy Future Resale Value
- The Reality: Investors often fear that chopping up a home’s interior with extra bedrooms permanently devalues the asset for future traditional buyers. Martinez circumvents this by strictly utilizing non-structural interior walls and drywall partitions. Because no permanent load-bearing changes are made, converting any of his properties back to a standard single-family layout costs a mere $3,000 to $4,000, preserving a clean exit strategy for any future retail buyer.
Implications for the Future of Real Estate Investing
The trajectory of Andres Martinez’s career offers a compelling window into the future of American housing and real estate entrepreneurship.
As traditional affordability metrics remain severely strained by elevated interest rates and inflated home prices, investors who rely strictly on conventional 30-year fixed mortgages and single-family rental yields are finding it increasingly difficult to achieve positive cash flow. Martinez’s success highlights the viability of alternative operational strategies—specifically the fusion of creative financing (subject-to acquisitions), high-density asset utilization (co-living conversions), and strict operational control (in-house general contracting).
For aspiring investors, Martinez’s journey demonstrates that capital constraints can be overcome with sweat equity, relentless prospecting, and a willingness to master the physical trades underpinning the asset class. From waiting tables and playing jazz in college to managing a multi-million-dollar portfolio of co-living spaces, Andres Martinez has proven that when traditional market doors close, ingenuity can build an entirely new blueprint for financial freedom.
