513 N San Marcos Street Rare opportunity to acquire a cash-flowing quadplex in the heart of Seguin's city center with an ultra-low 2.25 assumable loan and flexible owner financing available. This unique, income-producing property consists of four total units: a primary single-family residence, a detached garage apartment, and a duplex with two 1-bedroom, 1-bath units-offering excellent tenant diversity and strong rental appeal. Three of the four units have been recently upgraded with new flooring and new HVAC systems, significantly reducing near-term capital expenditures and improving tenant comfort and retention. Additional improvements throughout the property make this a true turnkey investment with reliable, consistent cash flow. The assumable 2.25 interest rate provides a massive advantage over current market rates, dramatically improving cash-on-cash returns, while the seller's willingness to owner finance the remaining balance creates a rare opportunity for favorable, creative financing with reduced upfront capital requirements. Located just minutes from downtown Seguin, shopping, dining, and major employment corridors, this property benefits from strong rental demand and long-term appreciation potential. Whether you're looking to expand your portfolio or secure a high-yield asset with unbeatable financing terms, this is a standout investment opportunity that is nearly impossible to replicate in today's rate environment.
