DALLAS, Texas — In late 2023, the American housing market slammed the door in the face of prospective buyers. With mortgage rates surging to 7.5%, millions of families and first-time buyers found themselves instantly priced out of homeownership. For Andres Martinez, a former jazz musician and restaurant waiter living in Dallas, this financial roadblock could have easily spelled the end of his real estate ambitions.
Instead, it served as the catalyst for an extraordinary career pivot.
Today, Martinez is a full-time real estate investor, general contractor, and co-living pioneer. His portfolio spans 14 properties (10 owned and four under management) housing an astonishing 107 co-living rooms. Generating roughly $27,000 per month in gross portfolio cash flow—and taking home a personal net cash flow of $12,000 to $14,000 monthly—Martinez has built a thriving empire. Remarkably, he achieves this while working out of his home, stepping into the field only once or twice a week.
This in-depth profile examines how Martinez navigated the grueling trenches of cold-calling, overcame devastating contractor fraud, and leveraged the burgeoning co-living asset class to achieve financial freedom.
Main Facts: The Anatomy of a Modern Real Estate Portfolio
To understand Martinez’s success, one must examine the metrics that define his current operations in the competitive Dallas-Fort Worth housing market. Rather than relying on traditional long-term rentals—which often yield razor-thin margins in high-interest-rate environments—Martinez adopted an aggressive, multi-layered investment strategy.

Chronology of a Breakthrough: From 600 Daily Cold Calls to Financial Freedom
Martinez’s journey into real estate was anything but an overnight success. Armed with a college degree in jazz studies and years of experience working for tips in restaurants, he possessed zero initial capital or formal background in property acquisition.
The Hustle: Surviving the Grunt Work
When soaring interest rates blocked Martinez and his wife from purchasing a home, he began exploring alternative ways to break into the market. This led him down a rabbit hole of creative financing strategies, specifically subject-to transactions and seller financing.
Without a marketing budget, Martinez relied entirely on sweat equity. He began calling every single listing on Zillow, frequently dialing between 500 and 600 numbers a day.
His persistence eventually bore fruit through his first deal: a wholesale assignment that netted him a $10,000 fee. However, the process was grueling. His second wholesale deal took nine months of relentless rejection, with Martinez calling 200 to 300 prospects daily. The stress bled into his day job; he was fired from his restaurant employment twice for taking seller calls during shifts.
Just two weeks after hitting rock bottom and mentally deciding to quit, a previously resistant seller texted him back. The buyer under contract had failed to secure financing, and the desperate homeowner was falling behind on payments. Martinez stepped in, closed the deal, and secured his first definitive proof of concept.
Discovering the Co-Living Model
While networking within a local real estate mastermind group, Martinez encountered the concept of co-living—renting out properties room by room to maximize yield.
Shortly thereafter, he identified a distressed five-bedroom, three-bathroom house facing pre-foreclosure. Because other local investors failed to understand the co-living model, the property sat unwanted. Martinez placed it under contract for just $3,000 down using a subject-to structure, successfully taking over the seller’s existing mortgage payments rather than attempting to secure a new, high-rate loan.
Supporting Data and Operational Challenges
Transforming a traditional single-family home into a high-density co-living space requires significant capital, meticulous project management, and unwavering resilience. Martinez faced trial by fire during his initial renovation phases.
Overcoming Contractor Fraud
For his inaugural co-living conversion, Martinez needed approximately $58,000 to construct three additional bedrooms, install new flooring, and furnish the interior. He partnered with an investor who provided 100% of the capital in exchange for a 50/50 equity split, leaving Martinez in charge of project oversight.
The arrangement quickly devolved into a crisis. The hired general contractor stole project funds and abandoned the job without paying her subcontractors. Consequently, Martinez was forced to pay roughly $40,000 out of pocket—dipping heavily into personal funds—to pay off unpaid laborers, redo subpar flooring, and complete the renovation himself.
Once stabilized, the numbers justified the pain:
- Rental Income: 4 standard rooms rented at $800–$850/month; 1 master suite with a private bathroom rented at $1,000/month.
- Gross Monthly Revenue: ~$6,500
- Carrying Costs (Mortgage, Taxes, Insurance): ~$2,100
- Net Monthly Profit: $2,700 to $2,800 from a single property.
Pivoting to In-House Construction
When the exact same contractor fraud pattern threatened his second co-living project—an eight-bedroom house featuring an ADU—Martinez decided to eliminate the weak link permanently.
Instead of hiring a third general contractor, Martinez approached the abandoned crew leader. He offered the lead worker steady, reliable employment in exchange for hands-on training in tile work, drywall installation, and flooring. By rolling up his sleeves, Martinez became his own general contractor.
By keeping a dedicated construction crew moving exclusively through his own properties rather than splitting their time across disparate job sites, Martinez slashed his renovation timelines from the industry standard of six to eight weeks down to just two weeks. This accidental pivot spawned a lucrative secondary business: Martinez has since acted as the general contractor for 29 co-living conversions belonging to other investors.
Official Perspectives and Industry Insights
Despite its growing popularity among modern investors seeking higher yields, co-living remains widely misunderstood by the general public and traditional real estate agents alike. Martinez addresses two of the most pervasive myths surrounding the asset class.
1. The Myth of Constant Turnover and High Friction
Critics of room-by-room rentals often argue that the model is overly active, plagued by perpetual tenant turnover and interpersonal conflict among roommates. Martinez refutes this based on operational data.
"I target working adults making enough to need housing but not enough to rent their own place," Martinez explains. "I always start on a month-to-month lease so either side can walk away cleanly before committing to a full year."
According to Martinez, this flexibility disarms tenants and filters out unstable applicants. Once a house is stabilized and the right chemistry is established, turnover drops dramatically. Notably, several tenants from his very first co-living property have repeatedly renewed, recently signing yet another full-year lease.
2. The Myth of Irreversible Property Alterations
Another common fear is that converting a home into a multi-room co-living facility devalues the asset or renders it unsellable to conventional retail buyers.
Martinez counters this by keeping his structural alterations non-permanent. Because his conversions rely exclusively on interior framing, drywall, and non-load-bearing walls, converting a co-living property back to a traditional single-family layout costs a modest $3,000 to $4,000. This ensures that his long-term exit strategy remains flexible, appealing equally to traditional families and future real estate investors.
Implications: The Future of Affordable Housing and Real Estate Investing
Martinez’s trajectory from a cash-strapped musician to a prominent Dallas real estate operator carries broad implications for the broader housing market:
- A Viable Solution for High-Interest Environments: As institutional mortgage rates remain elevated, creative financing strategies like subject-to deals and seller financing will likely continue to gain traction among resourceful retail investors.
- Addressing the Missing Middle: By converting underutilized suburban housing stock into accessible, room-by-room rentals, co-living operators provide a vital safety valve for working-class adults priced out of traditional apartment leasing.
- The Rise of the Operator-Contractor: Martinez’s transition from victim of contractor fraud to master builder highlights an essential lesson for modern real estate entrepreneurs: vertical integration and direct operational control are often the ultimate defense against project failure.
For Andres Martinez, the journey from dialing numbers on Zillow at all hours of the night to managing over a hundred co-living doors proves that determination, paired with an openness to unconventional strategies, can rewrite even the most discouraging financial outlook.
