They're done in the same visit for one reason: core aeration makes overseeding work. The plugs it pulls leave thousands of small holes, and the new seed falls right into them — giving the seed-to-soil contact that germination depends on.
On Nashville's hard clay, broadcasting seed onto the surface alone mostly fails — it dries out or washes away. Seed dropped into fresh aeration holes is protected, stays moist, and roots into loosened soil. That's why the combo dramatically out-performs doing either one by itself.
Do it in the fall — mid-September to late October. Soil is still warm enough for fast germination while the air has cooled, and tall fescue is heading into its strongest growing season. That gives the new grass six to eight weeks to establish before winter.
This is the same window as aeration and overseeding on their own — which is exactly why locals bundle them.

Bundled, aeration + overseeding runs about $0.13–$0.18 per sq ft in the Nashville area — so a typical 5,000 sq ft lawn lands around $650–$900. Buying the two together usually saves 10–15% versus booking them separately. See the full Nashville lawn care cost breakdown.

Yes. Core aeration leaves holes that give the new seed direct soil contact, so doing them together gives far better germination than either one alone — especially on Nashville's hard clay. Aerate first, then overseed immediately.

Once a year in the fall is right for most Nashville tall-fescue lawns, because fescue thins each summer and the clay soil re-compacts. Skipping years lets the lawn go patchy and weeds move in.
Yes — rent a core aerator (~$60–$90/day), then overseed with turf-type tall fescue and apply starter fertilizer. It's a heavy half-day of work, and consistent daily watering until germination is critical. Many homeowners hire it out to get the timing and watering right.
