Local insights from Redfin agents
Danville’s housing market remains strong, with median prices around $1.88 million. Buyers may find more choices and negotiation opportunities, while sellers should price competitively and present their homes well to attract offers.
Danville commands a high price tag, with median sale prices hovering between $1.8M and $2M. However, the frantic rushing seen in other markets isn't fully present here—homes are taking an average of 25 to 27 days to sell.
