Welcome to the 1899 Isaac Heffron Estate, a landmark in Galveston’s East End Historic District and a proven income-producing opportunity. Currently operating as a successful short-term rental, the home offers seven spacious guest suites, each with its own en-suite bath—an exceptionally valuable rental configuration. Beautifully preserved, the estate features original woodwork, a grand central staircase, marble and tile fireplaces, original flooring, and expansive wraparound porches. Major exterior updates include a new roof and fresh exterior paint in 2023. Set on nearly three full lots, the property includes an oversized garage and ample space for a future pool, further enhancing future revenue opportunities. This is a rare opportunity to acquire a historically significant, turn-key income property in one of Galveston’s most desirable districts. The home may also be easily converted to a stunning single-family residence if preferred.
