If you are drawn to The Sanctuary, you are likely weighing more than square footage. You are thinking about privacy, setting, timing, and whether the right home already exists or needs to be created. In a neighborhood where both custom homes and large homesites are available, that choice is especially relevant. This guide will help you compare both paths in practical terms so you can move forward with more clarity. Let’s dive in.
Why This Decision Matters in The Sanctuary
The Sanctuary in Mandeville is positioned as an environmentally planned, gated community with amenities that support an active lifestyle. Current listings describe miles of nature trails, a health and activity center, a fitness center, a tournament-size pool, tennis courts, a ball field, and an active HOA.
It is also a market within a market. While the broader Mandeville market currently shows 437 active homes, a median listing price of $380,000, and an average of 52 days on market, The Sanctuary sits in a more distinct luxury segment with both finished homes and land opportunities.
That matters because your choice is not simply whether to move. It is whether you want speed and certainty, or more control and customization.
When Buying May Be the Better Fit
Buying an existing home in The Sanctuary can offer a more immediate and concrete decision-making process. You can walk the property, evaluate the lot, see the landscaping, and understand how the outdoor spaces function before you close.
That visibility can be especially helpful in a neighborhood where site character matters. Driveways, tree cover, outdoor entertaining areas, and the relationship between the home and the lot are all easier to judge when the home is already complete.
A current resale example helps illustrate the point. A home at 5 Heron Lane is marketed as fully renovated, with major systems updated, a new roof, a pool, a generator, a custom stone driveway, mature landscaping, and outdoor entertaining spaces.
For many buyers, that kind of completeness removes a layer of uncertainty. You are not trying to imagine the end result. You are evaluating the finished product.
Key Advantages of Buying in The Sanctuary
If you are deciding between the two paths, buying a resale home may make more sense if you value:
- A clearer move-in timeline
- The ability to evaluate the finished house and lot in person
- Existing landscaping and outdoor living areas
- Fewer moving parts after contract
- Less coordination between design, permitting, and construction teams
In a limited luxury inventory environment, resale may also be the faster route to occupancy. The house is already built, which removes the separate lot purchase, design work, permitting, and construction process required for new construction.
Tradeoffs to Consider With Resale
Buying an existing home can still involve compromise. Even in a high-end community, some homes may reflect earlier design choices unless they have been substantially updated.
That does not mean resale is the lesser choice. It simply means you may need to decide which matters more to you: immediate use and certainty, or total control over finishes and layout.
When Building May Be the Better Fit
Building in The Sanctuary appeals to buyers who want a more tailored result. If your priorities include shaping the home around a specific lot, view, or site condition, the build path can offer more flexibility.
Current inventory shows that this is a real option in the neighborhood. One active land listing at 26 Preserve Lane, Lot 238, is offered at $275,000 for 6.7 acres, with HOA dues and custom architectural plans already prepared for the homesite.
That type of opportunity can be attractive if you want a home designed around the land itself. In some cases, having plans already prepared may shorten the early design phase, even if it does not eliminate the broader permitting and construction timeline.
Key Advantages of Building in The Sanctuary
Building may be the better fit if you want:
- More control over layout and finishes
- A home shaped for a particular homesite or view
- The opportunity to start with newer construction from the ground up
- Greater input into how indoor and outdoor spaces connect
For some buyers, that customization is worth the added time and coordination. In a neighborhood where homesites can be substantial, the ability to tailor the plan to the land can be a major advantage.
What Building Requires in St. Tammany Parish
New construction in St. Tammany Parish comes with a defined review process. The parish residential plan review checklist requires a completed permit application, parcel or assessment number, legal description, survey showing flood zone, a scale plot plan showing setbacks, stamped construction documents, contractor registration, and other supporting materials before a residential build can move forward.
That means the build path is not just about design inspiration. It also requires organization, documentation, and careful sequencing.
The parish also notes that some properties may need a coastal use permit if they are south of I-12. In addition, plans in a V flood zone must have every page stamped by a Louisiana-licensed architect or engineer.
Up-front permit costs are another part of the equation. The posted parish fee schedule lists $300 plus $0.10 per square foot under beam for new construction, a $50 plan review fee plus $0.01 per square foot under beam, and a $250 coastal use review fee if applicable. These fees are due when the application is filed.
Flood Zone and Site Planning Matter
In The Sanctuary, lot selection is about more than size and scenery. Flood zone status and site conditions can directly affect the timeline and documentation required for a new build.
If a homesite is in a floodplain, St. Tammany Parish requires elevation certificates before permit issuance, before the foundation is poured, and again before a certificate of occupancy or completion is issued. That creates additional coordination points during construction.
For buyers considering land, this is one of the most important practical steps. A beautiful lot may still come with requirements that affect schedule, planning, and overall complexity.
Timing and Carrying Costs
If your move depends on a specific timeline, buying often offers more predictability. A completed home can usually bring you to occupancy faster than a lot purchase followed by design, permit review, and construction.
Building often works best when you can tolerate a longer runway. Even with strong planning, you still need to account for approvals, inspections, and site-specific requirements.
There is also a tax timing consideration for new construction. The St. Tammany Parish Assessor states that a new building must be substantially complete by January 1 to appear on that year’s tax bill, with certificate of occupancy serving as the clearest proof, while prolonged construction can be handled on a percentage-of-completion basis.
That does not make building less appealing. It simply means completion timing should be part of your planning, especially if you are balancing multiple properties or carrying costs.
A Simple Way to Decide
If you are torn between the two options, start with your priorities instead of starting with the inventory. In The Sanctuary, both paths can work well, but they serve different goals.
Choose resale if you want a clearer move-in date, prefer to see the full property before closing, or want to avoid the extra coordination that comes with architects, builders, and permit sequencing.
Choose build if you want greater design control, are comfortable waiting through permitting and inspections, and want to shape the home around a specific lot or natural setting.
Questions to Ask Before You Commit
Whether you build or buy, the best decision usually comes down to the details. Before moving forward in The Sanctuary, make sure you verify the basics that can shape cost, timing, and overall fit.
Here are the most important questions to ask:
- What are the current HOA dues and rules for this property?
- What are the lot-specific setbacks?
- What is the flood zone status?
- Are there drainage requirements that affect the site plan?
- Is the builder properly registered if you plan to build?
- Does the lot already include usable plans, or will full design work still be needed?
These questions are practical, but they can save you time and prevent avoidable surprises.
The Right Choice Depends on Your Version of Luxury
In The Sanctuary, luxury can mean different things. For one buyer, it means moving into a finished home with mature landscaping, a pool, and outdoor spaces ready to enjoy. For another, it means starting with a homesite and designing every detail around the setting.
Neither path is automatically better. The right choice is the one that best matches your timeline, tolerance for complexity, and vision for how you want to live.
