Seagoville’s expanding community has homes available today, a 2027 target for an apartment-related building, and annual assessments buyers need to understand.
SEAGOVILLE — Santorini is already moving beyond the proposal stage, with completed houses being marketed alongside additional construction. But residents looking ahead to 2027 should distinguish between homes available for purchase, future residential phases, and the lagoon attractions promoted as the development’s centerpiece.
Public records establish a substantial housing and infrastructure framework. They do not establish that every planned amenity is finished or that the entire development will open next year.
A state construction registration provides one specific 2027 milestone: a December completion target for an apartment community’s club and leasing area.
Separately, Seagoville’s latest public improvement district documents show continuing financial obligations for assessed properties and important differences between the initial development area and the land planned for later housing.
For residents, the story involves both what Santorini could bring to Seagoville and what remains unverified.
Homes Available; Occupancy Count Unconfirmed
Megatel Homes markets Santorini from a sales center at 1150 Marina Drive, near the U.S. 175 and Malloy Bridge Road corridor.
At the time of review, the builder’s community page listed several houses as move-in ready and another under construction. Advertised examples included a $279,000 home at 417 Magellan Road and a $284,000 home at 426 Lana Drive. Prices and availability can change.
The distinction between completed inventory and occupied housing matters. A house offered for immediate purchase does not establish that a family has moved into it.
For example, the builder’s separate listing for 409 Magellan Road described that property as move-in ready and never occupied.
The materials reviewed did not establish a verified community-wide count of occupied homes, completed sales, or certificates of occupancy. Consequently, they cannot support a reliable calculation of how many residents already live in Santorini.
Those figures would provide a more useful measure of neighborhood growth than the number of homes appearing in sales advertisements.
Nearly 2,000 Houses in Original Framework
The original Santorini Public Improvement District service and assessment plan describes approximately 528 acres and anticipates about 1,938 single-family lots.
That is a long-term planning figure, rather than a count of houses currently standing.
The plan divides the property into an initial improvement area and a larger area for subsequent development. Improvement Area No. 1 encompasses about 136 acres and anticipates 393 single-family lots: 148 classified as 40-foot lots and 245 classified as 50-foot lots.
The remaining Major Improvement Area encompasses about 392 acres and anticipates another 1,545 single-family lots.
These figures show why Santorini deserves continued attention. If developed as anticipated, its housing inventory would extend well beyond the first streets and houses visible to buyers.
They also show why one construction date cannot describe the entire project. Individual homes, subdivision infrastructure, apartment facilities, and recreational attractions require separate progress checks.
What the Latest City Update Establishes
Seagoville’s 2026 annual PID update reports that the Santorini Phase 1A final plat was recorded on September 30, 2024.
The same update states that no plats had been recorded in the Major Improvement Area at the time the document was prepared.
That is a meaningful distinction between the initial subdivision activity and the remaining development framework. It should not be read as proof that no later application or work has occurred since preparation.
The update also expressly cautions that the authorized improvements and estimated costs described in the assessment plan do not guarantee construction timing or actual costs.
In practical terms, an assessment document establishes how infrastructure obligations are organized. It does not certify that a lagoon, entertainment building, or later residential phase has been completed.
A 2027 Target With Limited Scope
A Texas Department of Licensing and Regulation filing identifies a project called “Megatel Santorini Phase I,” with the facility described as “Club/Leasing.”
Its stated scope is new construction of the club and leasing area for an apartment community at the southwest corner of U.S. 175 and Highway 1389.
The registration lists May 4, 2026, as the construction start date and December 15, 2027, as the completion date. Its displayed status is “Project Registered.”
Those dates are a filed project schedule. Registration alone does not verify that construction began on schedule, remains on schedule, or has passed final inspections.
More importantly, this filing concerns an apartment-related facility. Its December 2027 target should not be presented as the opening date for the lagoon, all apartments, or the full Santorini development.
The record establishes an apartment component in the project pipeline, but does not resolve the current total apartment count or leasing schedule.
Lagoon Attractions Need Opening Confirmation
Megatel promotes a lagoon-centered community with attractions including a swim-up bar, surf simulator, bowling alley, arcade, and fitness center.
However, the builder’s community description continues to use forward-looking language about lagoon living and identifies entertainment features as part of the plan.
The public materials reviewed did not establish a confirmed lagoon opening date, an independently verified percentage of completion, or a facility-by-facility list of operating attractions.
That leaves several practical questions for both prospective homeowners and other Seagoville residents: Which amenities will open first? What access will homeowners receive? Will visitors from outside the neighborhood be admitted? What charges, reservations, or membership conditions will apply?
Until operating terms and opening announcements are documented, residents should treat those details as unresolved.
Seagoville’s Economic Development Corporation features Santorini on its website, reflecting the development’s prominence in local growth promotion. That promotion does not itself verify construction completion.
Assessments Add to Household Costs
Santorini’s public improvement district places infrastructure-related assessments on benefiting property. These obligations deserve attention alongside the mortgage, property taxes, insurance, and any separate association or amenity charges.
The city’s published 2026 buyer disclosures for Improvement Area No. 1 show the following amounts:
| Published disclosure | Principal assessment shown | Estimated installment due January 31, 2027 | Monthly budgeting equivalent |
| Lot Type 1 — 40-foot lot | $41,435.23 | $3,474.59 | $289.55 |
| Lot Type 2 — 50-foot lot | $46,614.64 | $3,908.91 | $325.74 |
The monthly figures divide the annual estimates by 12; they do not represent a separate monthly billing schedule.
The principal assessment is distinct from the annual installment, which includes financing and collection components. It also should not be confused with the property’s market value.
The disclosures project payments through 2054 and warn that estimated installments can change through annual updates.
The 2026 plan also identifies a Tax Increment Reinvestment Zone No. 1 credit mechanism, with the annual credit amount shown as to be determined. Applicable credits and parcel-specific adjustments therefore matter when establishing an owner’s actual bill.
These published examples are specific to the identified lot types in Improvement Area No. 1. They should not be applied automatically to every future Santorini property.
Buyers Need Property-Specific Costs
The city explains that PID financing can support public infrastructure such as roads, water, sewer, drainage, and open-space improvements.
A PID assessment is a separate obligation from ordinary property taxes. Seagoville identifies P3Works as its PID administrator and TXGovSolutions as the payment collector.
The buyer disclosures state that assessments may be paid in full and warn that unpaid obligations can lead to penalties, interest, and foreclosure.
For a household comparing homes, the useful number is the total recurring cost for the specific address. A purchase-price advertisement does not supply that calculation.
Buyers need written confirmation of the current assessment balance, annual installment, applicable credit, escrow treatment, association dues, and any separate lagoon-access charges. Each item answers a different question about the cost of living in the development.
What Residents Should Watch During 2027
The most useful next milestones will be measurable: additional recorded plats, home permits and occupancy records, verified construction progress on apartment facilities, and documented lagoon inspections and opening arrangements.
For nearby businesses, occupied homes would provide a firmer basis for estimating new customer demand. For public agencies, the pace and location of occupancy would help clarify service needs. Neither can be measured reliably from the ultimate lot count alone.
Santorini has an active home-sales operation and a substantial framework for further development. Its next chapter will depend on how quickly additional housing and promised attractions move from plans and registrations into completed, operating facilities.
For now, the available records support continued development activity and a specific apartment-facility target in 2027. They leave the lagoon’s opening date, the number of occupied homes, and the delivery schedule for later phases unconfirmed.
