Most buyers fall in love with the lake view first and ask about the monthly cost second. That is backwards. The smart move is to know the real number before you tour, so the view confirms a decision you have already run the math on.
Here is the honest breakdown of what it costs to own at Tennessee National — the 1,492-acre gated golf community on Watts Bar Lake in Loudon County, about 35 to 40 minutes from downtown Knoxville.
The HOA: $150 a month for single-family
Single-family homeowners pay a $150 monthly HOA fee. That covers the shared upkeep that keeps a gated community feeling like one — common areas, gate operation, and the day-to-day maintenance you would otherwise chase down yourself.
Compare that to many lake and golf communities in the Southeast, where dues routinely run $300 to $600 a month once you add club minimums and amenity fees. At Tennessee National, the base number is simple and it is low.
Property taxes: lower than almost anywhere up North
Loudon County property taxes are modest by national standards, and Tennessee’s statewide picture is what makes the real difference.
Tennessee has no state income tax. None on wages, none on retirement income, none on Social Security. For a retiree drawing from a pension or a remote worker keeping a six-figure salary, that single fact can outweigh the entire cost of the HOA several times over.
Run your own comparison. If you are moving from Illinois, New York, or California, the income tax you stop paying often covers your Tennessee National dues for the year — with money left over.
What you will not pay
Part of the real cost of ownership is the costs that are not there:
- No timeline to build. Buy a lot and hold it. There is no deadline forcing you to start construction, so there is no carrying pressure on your budget.
- No surprise second-course assessment. Tennessee National has one Greg Norman signature 18-hole course. You are not funding the upkeep of a sprawling multi-course operation.
- No state income tax. Worth repeating, because it is the line item that quietly changes the whole equation.
The purchase side: what you buy in for
Monthly cost starts with what you buy. At Tennessee National, homesites and lots run from $99K to $850K, so the entry point flexes to your plan. A wooded interior lot sits at the low end; a premium homesite with long water views sits at the high end.
For the first time, dockable lake lots are being offered, and they can add a $250K to $500K premium over a comparable non-dock lot. That premium buys deep-water access on Watts Bar Lake’s 80 miles of navigable shoreline — the difference between living near the water and stepping off your own dock. Availability is limited, which is worth knowing if a dock is non-negotiable for you.
Because there is no timeline to build after a lot purchase, you can buy the land now, lock in your spot, and build when your timing and budget line up. That flexibility is itself a cost-control tool: you are not forced into construction on someone else’s schedule.
Golf and the marina: optional, not baked in
Your monthly base cost does not assume you golf every day or keep a boat in the water year-round. Golf membership and marina slips are there when you want them — including reciprocal play at more than 800 courses worldwide through the membership — but they are choices layered on top of a low base, not mandatory minimums hidden in your dues.
That structure matters. It means a couple who wants the lake and the gate, but only the occasional round, is not subsidizing someone else’s daily tee time.
How it compares to where you live now
The honest way to judge cost is side by side with your current home. Start with three numbers you already know: your current property tax bill, your current state income tax, and any HOA or club dues you pay today.
Now picture the Tennessee National version. The $150 monthly HOA replaces most bundled amenity fees. Loudon County property tax tends to run well below what owners pay in the Northeast, the Midwest, or California. And the state income tax line drops to zero — Tennessee does not tax wages, retirement income, or Social Security.
For a household relocating from a high-tax state, the income tax savings alone often exceed a full year of HOA dues. That is why so many of the 300-plus families already living here — part of a community with 400-plus active members — describe the move as a lifestyle upgrade that also lowered their monthly outlay. The lake, the Greg Norman signature course, and the marina come on top of a number that, for many, is simply lower than what they were paying before.
The headline number most owners quote: $150 a month in HOA, plus modest Loudon County property tax, in a state with zero income tax.
Run the math before you fall for the view
Add it up for your situation: $150 monthly HOA, your Loudon County property tax estimate for the home or lot you are considering, and then subtract the state income tax you will no longer owe. For most buyers relocating from a high-tax state, the net monthly cost of living on Watts Bar Lake is lower than the cost of staying where they are.
Bring your numbers when you come see it. The view sells itself — but it is the math that lets you say yes without hesitating.
