The 16-Week Inventory "Spike": Why San Diego Sellers Are Chasing the Market (and How to Lead It)

Week Ending January 25, 2026

The San Diego housing market continues to show a clear split between fresh inventory and properties that have lingered past the two-week mark. While overall activity is stabilizing, the current 30-year fixed mortgage rate sits at 6.17%, according to Mortgage News Daily, providing a consistent baseline for buyers navigating this bifurcated landscape.

🏠 DETACHED HOMES: Timing the Golden Window

This week, the Weeks of Inventory for detached homes spiked to 16 weeks, up from 11.5 last week. While this looks like a significant jump, it is primarily a mathematical artifact: we are seeing a seasonal increase in active inventory (up to 2,213) coupled with a temporary dip in closings from homes that went under contract during the slower holiday weeks.

To find the true signal through the noise, we look at the 4-Week Rolling Average Sold Price, which currently stands at $1,073,900. This is a 1.9% increase over the previous 4-week average and a substantial 9.6% jump over last year’s rolling average of $979,450. Interestingly, this week’s median sold price of $1,110,600 is actually outperforming the rolling averages, showing that the market is gaining momentum as we exit the holiday lull.

The most telling data point is the $99,000 price delta between Fresh listings (under 14 days) and the general market. Fresh pending listings have a median asking price of $1,199,000, while the broader pending pool sits at $1,100,000. This suggests that properties priced correctly from day one are being rewarded, whereas stale inventory often represents sellers who may be performing price adjustments while chasing a market that has already moved on.

🏢 ATTACHED HOMES: HOA Fees & Insurance Realities

The attached market (condos and townhomes) is facing a unique set of headwinds as ever-increasing HOA fees and insurability issues continue to impact buyer purchasing power across Southern California.

The 4-Week Rolling Average Sold Price for attached homes is $650,324, which is a 0.4% decrease compared to the previous 4-week average and a 3.3% decrease from last year’s 4-week average. This week's median sold price of $610,000 shows that current closings are trailing the rolling average, indicating that buyers are becoming more sensitive to the total monthly cost including those rising secondary fees.

However, the Fresh listing premium remains resilient. New listings that went pending in under 14 days commanded a median asking price of $774,999, nearly 19% higher than the overall pending median of $649,999. Even with insurance hurdles, the right property in the right complex still moves aggressively if priced correctly.

💡 What This Means For You

🛒 For Buyers

The spike in weeks of inventory is a gift of selection. While the fresh listings move at a premium, properties that have sat for 14+ days may offer room for negotiation, especially in the attached segment where HOA and insurance costs are weighing on other buyers.

💰 For Sellers

Pricing right in the first 14 days is the difference between a record sale and a long, frustrating wait. Listings that go pending quickly are currently asking significantly more than those that linger. Don't be the seller chasing the market: lead it with a sharp initial price.

🪺 For Homeowners

Despite the seasonal fluctuations in inventory, your equity remains in a very strong position. With the 4-week rolling average for detached homes up nearly 10% year-over-year, San Diego real estate continues to be a premier long-term asset.
