The backyard at 140 Gustav Lane in San Marcos is where this 5-bedroom, 3-bath home in San Marcos really comes alive. Built in 2023 on 1.056 acres, this is the kind of property where neighborhood kids know exactly where to gather on a Saturday afternoon. The covered patio with vaulted wood ceilings is pre-plumbed for an outdoor kitchen, meaning you're never more than a few steps from grilling season. The built-in speaker zones mean your music follows you from the kitchen island to the back fence.
This is a properly fenced yard with room to breathe. There's space for a trampoline, a fire pit circle, a cornhole tournament, or whatever your crew dreams up. The fully landscaped lot backs up to open country feeling, which is rare for a home at this price point - $266 per square foot for 3,193 square feet. The extensive irrigation system keeps the grass game strong without the guesswork. You've got a 3-car side-entry garage plus a detached shop with 220V service, so storage for equipment, toys, and projects isn't an afterthought.
Inside, the open floor plan with 10-foot ceilings and oversized picture windows means you can stand at your Calacatta quartz kitchen island and see everything happening in the backyard. The induction cooktop and stainless steel appliances are smart home connected, the primary bedroom anchors the main floor with a spa bath that has dual shower heads and bench seating, and there's a dedicated office for the work-from-home crowd. Navarro ISD serves the property with elementary, middle, and high schools all in the same district, which simplifies the logistics when kids need different start times.
The energy efficiency is built in - 18 SEER HVAC, spray foam insulation, smart thermostat, and Energy Star appliances mean your utility bills won't surprise you. The smart home package includes built-in speakers, security system, and pre-wired cameras. This is the kind of house where you can actually use your backyard for nine months out of the year in Texas, and the covered patio with vaulted ceilings keeps you comfortable in the heat. Days on market shows zero, which tells you what the neighborhood already knows about homes like this in San Marcos.
