All city figures cover single-family closed sales in August 2026: median sale price, average days on market and year-over-year change in the monthly median versus August 2025. These are city aggregates, not changes in the value of an individual home.

Luis's take

August's county median rose year over year, while active listings were lower than July. The city table shows different price trends across the county. I use this snapshot as a starting point for questions about timing and budget. MLSListings county snapshot; MLSListings July summary.

What this means for you

If you're buying

As arithmetic only, applying the reported 107% ratio to a hypothetical $2,000,000 asking price gives $2,140,000, a $140,000 difference. That example doesn't predict a closing price or set an offer budget.

If you're selling

The same arithmetic gives $2,140,000 from a hypothetical $2,000,000 asking price at 107%. It isn't a valuation or a calculation of seller proceeds. County averages don't establish the right price for an individual home.

For investors

GAP. A primary public source for condo-only prices, annual change and comparable days on market wasn't retrieved. The available MLSListings series combines condos and townhomes, so it doesn't verify the PDF's condo-only comparison. MLSListings county snapshot.
