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.
