The Big Picture

The median home price in Collin County was $440,995 in September, down 2% from a year ago. Homes spent a median of 69 days on the market and sold for 93.6% of their original list price. There are 5,944 homes for sale and 4.9 months of supply, up from about 4.2 months last September. That puts us in a balanced market where neither side holds all the cards.

Fall is also a naturally slower season. 1,218 homes closed in September and 1,386 went under contract, both below this time last year. That means less competition for buyers and a bigger payoff for sellers who get the details right.

What This Means if You're Thinking About Selling

Pricing matters more in this market than it has in years, and September showed it clearly.

Homes priced right from day one sold in a median of 22 days for 98.2% of their original list price. Homes that needed a price cut sat for a median of 98.5 days and sold for 90.8%. On a $450,000 home, that gap is roughly $33,000, plus two and a half extra months of payments, showings, and stress.

Nearly two out of three homes that sold (63.5%) went through a price reduction first. You can avoid becoming part of that number. It starts with an honest pricing strategy built on what's actually selling in your neighborhood, not what the house down the street is listed for.

What This Means if You're Looking to Buy

This is one of the better windows for buyers we've seen in a while. 60% of sellers paid concessions in September, with a median of $10,000, about $1,300 more than last year. That money can cover closing costs, buy down your rate, or fund updates after you move in.

With 5,944 homes on the market and most sellers already adjusting their price, you have real choices and real leverage. And with fewer buyers shopping this time of year, the ones who show up prepared can negotiate from a position of strength.
