About This Home
Fascinating and unique property in San Marcos could be all yours! 4 lots with 3 homes + efficiency apartment offers tons of potential and opportunity. Fourth lot has recently been cleared off further as well. Currently zoned SF6 (single family), but could request rezoning. In-ground pool needs some TLC and you'll have your own oasis. Main home offers a sprawling floor plan with 3 bedrooms, 2 full baths and multiple storage and flex areas. All three secondary units have had refreshed finishes. Front deck of the main home offers stellar views. Investor special with great rental and further development potential! Efficiency apartment leased month-to-month @ $895 - 1009 Hiilyer leased through 5/2027 @ $1,850 - 1001 Hillyer seeking tenants - 1000 Advance (main home) @ $1,900.
This 1.21-acre compound at 1000 Advance Street in San Marcos neighborhood is built for backyard living at scale. The main residence offers 3 bedrooms and 2 full baths across a sprawling floor plan, but the real story is the outdoor space and the multi-unit potential that makes this property work as either a family compound or an income-generating investment.
The backyard centers on an in-ground pool that anchors everything - this is where summer afternoons happen. The pool area sits on grounds large enough to host the neighborhood cookout without feeling crowded. With 1.21 acres across four distinct lots, you have room for actual lawn games, a proper grill station, and the kind of space where kids can run without hitting property lines. The main home's front deck delivers views that make morning coffee something to linger over, and the lot configuration means your outdoor entertaining doesn't feel hemmed in by neighbors.
What makes 1000 Advance Street work as a daily-living space is the flexibility built into its bones. The main residence connects to three additional leased units currently generating income - a one-bedroom at $2,200 monthly, another at $1,850 monthly through June 2026, and an efficiency apartment at $895 to $1,009 monthly. The fourth lot has been cleared, opening options. Current zoning is SF6 single-family, but rezoning potential exists if you're thinking bigger development.
For families in the San Marcos CISD, the property feeds into Crockett Elementary, Miller Middle School, and San Marcos High School. The San Marcos location keeps you close to downtown San Marcos while maintaining the kind of acreage that feels genuinely rural by Texas suburban standards.
At $174 per square foot for 5,548 square feet, and with all units currently leased through mid-2026, the property carries strong immediate cash flow. Days on market at 232 reflects the niche nature of multi-unit residential land in San Marcos - this isn't a traditional single-family home, and that's exactly the point. Whether you're looking to create a multigenerational retreat with serious backyard infrastructure or you're an investor seeing development and rental potential, the bones are here: acreage, pool infrastructure, leased income, and room to expand.
