## Description

### Agent Description
Rare opportunity to own a spacious 2.38 acre, single-story property and a detached guest house in a highly desirable San Marcos location. The main residence offers approximately 1,441 square feet of living space with 3 bedrooms and 2 bathrooms. A detached guest house, approximately 1 bedroom and 1 bathroom, features its own kitchen and living area, providing excellent flexibility for extended family, guests, rental potential, or additional workspace. The expansive, private lot offers RV parking, mature trees, and plenty of room for recreational vehicles, equipment, hobbies, or outdoor enjoyment. The property requires interior renovation and is being sold AS-IS, presenting an excellent opportunity for investors, builders, or owner users looking to renovate, customize, and add value. The property is zoned R1-20, offering potential for agricultural, horticulture or equestrian use and possible future development; buyer to independently verify zoning, permitted uses, and development potential with the appropriate authorities. Conveniently located just minutes from the 78 freeway, shopping, dining, schools, and other local amenities, this property offers a rare combination of land, location, flexibility, and upside potential.
