New Homeowner Data in Union County, SC | ListCentral.US

Union County was built by cotton mills, and the mills built the houses. Whole neighbourhoods went up at once in the first decades of the twentieth century — small frame houses, close together, laid out in rows, built to a handful of repeated plans around the mills in Union, Buffalo, Jonesville and Lockhart.

A century later that history produces something commercially unusual. These houses are among the cheapest in the state, they are changing hands steadily to first-time buyers and investors, and because they were built identically, the same problem exists on the same street in the same form. Diagnose one and you have diagnosed forty. That is the opportunity in Union County new homeowner data, and it is quite different from working a county of one-off houses.

What the data is

Recent residential purchasers across Union County, built from the county's land records — in South Carolina's smaller counties these are kept with the Clerk of Court rather than a separate Register of Deeds. Each record carries owner name, property address, mailing address, parcel ID, last sale date, last sale amount, document type, county and state. Deduplicated, delivered as CSV or Excel.

What a 1910s mill house actually has

Predictably, and almost always in the same combination:

• Original wiring. Knob-and-tube or early cloth-insulated circuits, an undersized panel, few outlets and no grounding. This is the first safety item and frequently the first thing an insurer asks about.
• Pier-and-beam construction over an open crawl space. Sagging floors, failed sills and joists, no vapour barrier, and moisture doing slow damage underneath.
• Asbestos-cement siding applied over original weatherboard in the mid-century, which needs handling rather than ripping off.
• No insulation in the walls and very little in the attic, which is the cheapest comfort improvement available and the easiest sale.
• Single-glazed wood windows, often original, often worth restoring rather than replacing on the better examples.
• Chimneys from a coal or wood era, unlined and unused, and a genuine hazard if someone decides to light a fire.
• Galvanised supply plumbing and cast iron drains at the end of their lives.
• Heating added later — sometimes a floor furnace or wall unit that should be replaced outright rather than serviced.
• Lead paint throughout anything pre-1978, so lead-safe practice is not optional on renovation.

The scaling argument is the business case: a contractor who works out the right specification for one of these houses — the panel, the sill repair, the encapsulation, the insulation package — can offer it street by street at a known price, with a known labour time, and quote confidently from a photograph. Very few contractors think this way, and in a county of repeated house types it is a real advantage.

Two buyers, and they are easy to tell apart

Compare mailing address to property address. Where they differ, the buyer is not moving in: an investor or a landlord, wanting make-ready work, cost certainty, turnover speed and a contractor who can be trusted unsupervised. They buy again, which makes them worth more than a single job.

Where they match, and the price is low, you likely have a first-time owner-occupier in an old house with no idea which problems are urgent and which can wait. They need honest triage — safety first, then the envelope, then everything else — plus staged work and realistic sequencing. The business that gives them that becomes their contractor for years, and tells them frankly when something is not worth doing.

Sort owner names as well: repeat and entity names confirm the investor segment.

An honest note on the market

Union County's population has been declining for decades, as it has across much of the rural Upstate, and transaction volume is modest. The realistic approach is a wide date range rather than a large record tier, or ordering Union alongside Spartanburg, Cherokee, Laurens or York so a mailing is worth producing — and the compensating advantage is that almost nobody markets here, so there is very little competing post on the mat.

Beyond the towns

Outside the mill villages the county is farmland, pasture and pine, with the Broad and Tyger rivers, the Sumter National Forest and a good deal of hunting land. Those buyers need wells, septic, propane, fencing, land clearing and timber management, and absentee tract owners need access, boundaries and someone local to look in.

Upstate conditions apply: red clay that moves, so grading and gutters matter; humid summers, so termite bonds are ordinary practice; pines and hardwoods over roofs; ice storms; hail. A cheap radon test is sensible in this granite geology. And South Carolina's lower owner-occupied assessment ratio must be applied for with the county assessor — which matters especially to a first-time buyer on a tight budget.

Coverage

Union (the county seat), Jonesville, Carlisle, Lockhart, plus the unincorporated county including Buffalo, Kelly, Monarch Mill, Ottaray, Santuc and Sedalia.

Who uses it

• Electricians — panel and circuit replacement; the clearest first job in the county
• Plumbers — repiping and drain replacement
• Insulation contractors — the cheapest win on an uninsulated house
• Pier-and-beam levelling, sill and joist repair specialists
• Crawl space encapsulation and moisture specialists
• Roofing, siding and window companies, with asbestos-aware practice
• HVAC contractors — replacing obsolete heating outright
• Chimney inspection and lining services
• Make-ready and turnover contractors — the investor segment
• Property managers
• Pest control companies — termite bonds
• Well, septic, fencing and land clearing services — the rural county
• Insurance agencies and mortgage professionals — first-time buyers need both, and wiring affects cover

Freshness

Union County snapshots are rebuilt from current county records on a monthly or weekly cadence and deduplicated before release, covering the period you select. Last reviewed: September 2026.

Cost and comparison

One-time purchases priced by record volume — commonly 200, 500 or 1,000 records — with current pricing on each product page and no subscription. Buy the date range rather than the volume here.

Compared with alternatives: MLS coverage of low-value and investor transfers is thin; national brokers have little currency at this scale; auction and tax-sale lists cover a different stage entirely. A recorded deed is the reliable signal that a house has changed hands.

Union County new homeowner data — FAQ

Which office is the source?
The county's land records, kept with the Clerk of Court as in South Carolina's smaller counties.

Why does repeated house design matter commercially?
Because mill villages were built to a few plans at once, so the same defects recur in the same form. One correct specification can be offered street by street at a known price.

How do I separate investors from first-time buyers?
Mailing address differing from property address, plus repeat and entity owner names, indicates an investor. Matching addresses at a low price usually means an owner-occupier.

Does the data give year built or construction type?
No; match parcel IDs against assessor data. Much of the town housing dates from the early twentieth century.

How many records should I expect?
Few. Widen the date range or add neighbouring Upstate counties — and note that very little competing mail reaches these households.

Are phone numbers included?
No; append them through optional skip tracing.
