Ask most buyers touring Lake Mary what drives their monthly payment, and they will name the mortgage, the tax bill, maybe the insurance premium that has everyone in Florida wincing lately. Almost none of them will mention a Community Development District, and that is exactly the gap that costs people money.
Here is the part that surprises even longtime residents. Heathrow, the guard-gated address most people picture when they think of prestige real estate in Lake Mary, carries no CDD assessment at all. None. The community that has pushed into seven-figure average sale prices, with 2024 sales averaging near $985,000 and 2026 listings ranging from the mid-$600s for original-condition homes to more than $1.6 million for renovated lakefront and golf estates, funds its gates, guards, and grounds through quarterly POA dues instead of a bond repayment line on the tax bill. Meanwhile, plenty of newer, less expensive master-planned product across Seminole County layers a CDD assessment on top of its HOA dues, adding real annual cost that never shows up in the list price.
That is the mechanism worth understanding before you compare two Lake Mary listings on price alone. The sticker price ranks homes. It does not rank what they cost to own.
What a CDD Actually Is, and Why It Skips the For Sale Sign
A Community Development District is not a fee a developer invented to pad a budget. It is a special-purpose unit of local government, created under Florida law, with the authority to issue tax-exempt bonds that pay for roads, water and sewer lines, and amenity infrastructure before a single house is finished. Property owners inside the district then repay that debt through an annual assessment, split between a capital component that retires the bond and an operating component that funds maintenance.
The district is governed by a Board of Supervisors, elected initially by the landowners and then transitioned to residents after six years of operation, according to the Central Florida CDD network that tracks these districts. Meetings and budgets are public record under Florida's Sunshine law, and the board holds an annual hearing before setting the year's assessment. None of this shows up on a listing photo. All of it shows up on the tax bill, every single year, for as long as the bond is outstanding.
The reason Heathrow skipped this structure comes down to when and how it was built. Development beginning in the late 1980s predates the era when CDDs became the default financing tool for large-scale Central Florida communities. Newer master-planned neighborhoods elsewhere in the region, particularly ones built in the last fifteen years, frequently use the CDD model instead, because it lets a developer finance infrastructure at government bond rates and hand the repayment obligation to the homeowners who benefit from it.
Seminole County has one of the higher concentrations of these districts in Central Florida, which means the odds of encountering one while house hunting here are better than average, not worse.
The Math Nobody Runs Until They're Under Contract
Buyers ask about HOA dues almost by reflex. Almost nobody asks the follow-up question that actually changes the monthly number.
| Cost component | What it funds | Who sets it |
|---|---|---|
| HOA or POA dues | Gates, landscaping, pools, sometimes cable or internet | Community association board |
| CDD capital assessment | Bond repayment for roads, water, sewer, amenity construction | Set by bond schedule, amortized 20 to 30 years |
| CDD operating assessment | Ongoing maintenance of CDD-owned facilities | CDD Board of Supervisors, set annually |
In Seminole County today, CDD assessments commonly run in the range of $1,500 to $4,000 a year, layered directly on top of HOA dues that often add another $200 to $400 a month in master-planned communities. Stack both together and total annual carrying costs beyond the mortgage and property tax bill can push past $5,000, sometimes closer to $10,000, depending on the community and the size of the original bond.
That is not a rounding error. On a monthly basis it can mean the difference between two homes priced fifty thousand dollars apart actually costing the same to carry, or two homes priced identically costing hundreds of dollars a month apart. A CDD assessment cannot be negotiated away or paid off by simply asking. It runs with the land, not the owner, which means whoever holds the deed inherits whatever balance remains on the bond.
Same City, Very Different Bills
Lake Mary is not one market with one fee structure. It is a patchwork of subdivisions built across four decades, and the range of what buyers encounter reflects that history.
Griffin Park, at the corner of Lake Mary Boulevard and Longwood-Lake Mary Road, is a gated 144-home mix of single-family houses and townhomes priced roughly $300,000 to $650,000. A few miles south off Lake Emma Road, Huntington Landing spans 326 lots across its Huntington Ridge and Huntington Pointe sections, with pricing generally under $400,000. On Markham Woods Road, Magnolia Plantation offers a gated golf setting across 498 lots, while Hanover Woods, just up the same corridor, is a smaller 74-lot custom-home enclave. Heathrow Woods sits directly across from Heathrow itself, a 208-lot subdivision of custom homes on minimum one-acre lots that has traded from the $550,000s up toward $3 million. On the more affordable end, Hills of Lake Mary off SR 46A offers 321 homes typically well under $300,000.
Each of these communities has its own governance, its own age, and potentially its own CDD status. None of that is visible from a portal search result. It only becomes visible when someone asks the specific question, community by community, before writing an offer rather than after.
The pattern that matters is not which particular subdivision does or does not carry a bond. It is that the answer does not track with price the way most buyers assume. A modest townhome and a seven-figure estate can sit on opposite sides of the same question, and the only way to know is to ask it directly rather than infer it from the address.
Three Questions Before You Compare Two Listings on Price
A buyer who runs these before writing an offer avoids the surprise that shows up on the first escrow statement instead of the first showing.
- Is there a CDD, and what is the current outstanding balance? Ask for the current figure, not the original bond amount. Older CDDs may have paid down a meaningful share of their debt, which lowers the annual assessment even though the community was built with one from the start.
- Can the assessment be prepaid, and has a previous owner already done so? Some CDD debt allows prepayment in full. If a prior owner already retired part of the capital assessment, the remaining annual charge on that specific lot may be lower than a neighbor's on the same street.
- What does the full monthly number look like once everything is added? Mortgage principal and interest, property tax, homeowner's insurance, HOA or POA dues, and any CDD assessment divided by twelve. That is the number that determines affordability, not the number on the sign in the yard.
None of these questions require a real estate license to ask. They require knowing the question exists, which is the part most portals and payment calculators leave out.
A Few Straight Answers
Does a CDD assessment show up on the property tax bill? Yes. It is collected as a non-ad valorem assessment alongside property taxes, which is part of why it is easy to miss when a buyer is only comparing sale prices during a search.
Is a CDD a sign that a community is lower quality? No. It reflects a financing choice made at the time of development, not a judgment on the finished product. Some of the most amenity-rich communities in Central Florida use CDD financing precisely because it let the developer build pools, trails, and clubhouses concurrently with the homes instead of years later.
Can a new owner get rid of an existing CDD? No. The obligation is tied to the parcel. It transfers with the deed regardless of who buys the home, and it remains until the bond is retired.
Two homes in Lake Mary can carry the same list price and very different bills the day the first tax notice arrives. The only way to know which one you are looking at is to ask before you write the offer, not after you have already fallen for the floor plan.
