A sprawling Thonotosassa estate known for its replica Oval Office, private movie theater and wedding venue is back on the market for $18.9 million. Mision Lago Estate covers nearly 22 acres on Lake Thonotosassa and is being offered alongside an adjoining commercial property, with the listing highlighting possibilities for private use or hospitality ventures.
Key takeaways
Mision Lago has returned to the market at a reduced asking price after a prior listing expired. Its expansive grounds and unusual themed amenities distinguish it from a typical luxury home, while its event business adds another dimension to the offering.
- Asking price: $18.9 million, down from $22.9 million in August 2025.
- The property includes a 31,500-square-foot mansion and 682 feet of lake shoreline.
- The estate also operates as a wedding and events venue.
- The listing is being marketed with a neighboring commercial property, though the details of what would transfer with the venue business are not specified.
A distinctive lakefront compound
Located at 11865 Fort King Highway, the gated estate spans nearly 22 acres along Lake Thonotosassa. Its Mediterranean and Italian rustic-inspired main residence has six bedrooms and 12 bathrooms. Christine Mastrilli of Compass is handling the listing.
The home’s interior includes an Oval Office replica featuring a copy of the Resolute desk, a 45-seat underground theater modeled after Tampa Theatre, a sports memorabilia room and a lounge inspired by Tropicana Field. Other features include a chef’s kitchen and spaces designed around the owners’ travels.
Gardens, vineyard and event spaces
Outdoor amenities include a zero-entry lagoon-style pool with waterfalls, koi ponds, mature olive groves, an orchid nursery, an air-conditioned greenhouse and a 2.7-acre vineyard. An air-conditioned barn serves as an event space, and the estate’s website promotes five indoor and outdoor venues. It says the property hosts an average of one event a day.
The wedding business grew out of a family celebration: the owners’ son Rhett married at the estate, inspiring the conversion of the horse barn into an event venue, according to the property’s website.
The estate’s backstory and new asking price
June Simpson and her late husband, Tom, built Mision Lago for about $18 million in 2012. The couple had sold their Tampa-based company, Health Advocates, to AmerisourceBergen in 2006 in a deal valued at about $83 million in cash. They later returned to the Tampa area after buying a home in Malibu, with luxury builder Gary Brown designing the estate in the style of the Spanish missions of Santa Barbara.
The property was listed for $22.9 million in August 2025. That listing expired on Aug. 31, with the asking price then just under $20 million; the new $18.9 million price is about $4 million below the original ask. Compass is marketing the residence together with a commercial property at 11901 Fort King Highway, describing the combined offering as a potential corporate retreat or boutique hospitality destination. The listing does not clarify what, if anything, from the venue business would be included in a sale.
