As Mortgage Rates Hold Near 6.3%, Upstate Builders Sweeten Deals to Keep New Homes Moving

GREENVILLE, S.C. — Homebuilders across the Upstate are leaning harder on rate buydowns and closing-cost credits this summer as mortgage rates hover near 6.3% to 6.5%, a sign that supply and demand across Greenville and Spartanburg counties are pulling in opposite directions even as the region keeps adding rooftops.

In Greenville, the market has tilted toward buyers. The median sale price sits near $480,000 in the city and in the $340,000 to $380,000 range across the broader county, with homes taking a median 52 days to sell, up slightly from a year ago. Active inventory has climbed by roughly 21% to 28% year-over-year, giving buyers a 4.7-month supply to shop from and pushing sellers to accept 98.31% of asking price on average, according to Redfin and Zillow market data.

Spartanburg tells a different story. The median home price there has climbed to $266,500, up 6.6% from a year ago, even as homes are taking longer to sell — a median 82 days, up nearly 8% year-over-year. Inventory remains thin at roughly a 1.16-month supply, keeping sellers in a stronger negotiating position and pushing homes to sell for close to 98.68% of list price. Forecasters expect Spartanburg prices to appreciate another 2% to 4% before year’s end.

That divergence is reshaping how builders sell new construction. Rather than cut list prices outright — a move that can spook recent buyers and complicate future appraisals — builders are increasingly offering temporary and permanent mortgage rate buydowns, along with closing-cost assistance, to make monthly payments more competitive with resale homes. A 2-1 buydown, for example, can shave two percentage points off a buyer’s rate in year one and one point in year two before the rate reverts, while permanent buydowns lock in savings for the life of the loan.

The incentives reflect an Upstate housing market still absorbing a wave of new supply after years of rapid population growth tied to manufacturing, logistics and professional job gains. Greenville County continues to add new-home permits at a faster pace than in 2024 or 2025, and builders in outlying communities from Easley to Simpsonville are competing for buyers who might otherwise choose an existing home now sitting longer on the market.

For buyers, the shift means more room to negotiate, particularly in Greenville, where longer days on market and rising inventory have eroded some of the urgency that defined the region’s pandemic-era boom. For sellers and builders in tighter submarkets like Spartanburg, pricing power remains intact, but longer selling timelines suggest even strong markets are cooling from their recent peaks. Developers and investors watching both counties say the split market underscores why Upstate housing strategy increasingly has to be hyperlocal — a subdivision in Greenville and one 30 miles away in Spartanburg County can face very different demand conditions in the same season.
