Why Koti picked this home
This spacious 1,874 sqft home features multiple living and dining areas on a generous .49-acre lot just outside San Marcos.
Set on .49 acre just outside San Marcos, this unique property offers an impressive amount of usable space, both inside and out. Mature oak and pecan trees shade the fully fenced property, including a beautiful grandfather oak that covers much of the front yard. A gated entrance and additional backyard gates provide privacy and easy access, including a gate large enough for an RV. The 1,874-square-foot, three-bedroom, two-bath home offers multiple living and dining areas, including a 330-square-foot sunroom across much of the front of the home. The kitchen features granite countertops and soft-close cabinetry, with an adjoining utility room providing washer/dryer space and additional storage. The spacious primary bedroom includes a large walk-in closet. Across the back of the home is approximately 700 square feet of covered decking with access ramp, ceiling fans, built-in workshop/storage space, and a functioning hot tub—a great extension of the living space beneath the surrounding trees. A standout feature is the approximately 1,000-square-foot detached workshop/studio with two mini-split systems and its own attached deck. Used for years as a music studio, this substantial building offers tremendous flexibility for music, art, hobbies, a workshop, or home office. With additional finish-out and any required approvals, it also offers potential for an ADU or separate living space for a multi-generational household. An extensive concrete driveway provides plenty of parking along with a 440-square-foot covered carport. The property is served by city water and private septic. Located off Hunter Road with quick access to IH-35, shopping, medical facilities, the San Marcos Premium Outlets, and H-E-B plus!. The residence incorporates a single-wide manufactured home with substantial site-built additions, including the front sunroom and utility room. Due to the unique construction, this must be a cash purchase.
