Simi Valley Housing Market Update September 2026: Inventory Rises, Market Holds Steady

Simi Valley’s single-family housing market is holding fairly steady as we move through September.

As of September 15, 2026, the median list price is $925,000, inventory has increased to 176 homes, and the Market Action Index is 42, down slightly from 43 last month.

That keeps Simi Valley in a Slight Seller’s Advantage, but the latest numbers also show a market where buyers are paying close attention to price.

One number that stands out is this: 42% of current listings have had a price reduction.

So while sellers still have an advantage overall, this is not a market where every home can simply be priced aggressively and expect buyers to follow.

Is Simi Valley a Buyer’s or Seller’s Market?

Simi Valley is currently showing a Slight Seller’s Advantage.

The Market Action Index compares the pace of sales with available inventory. When demand is stronger relative to supply, the index moves higher.

This month, however, the index has eased slightly from 43 to 42, while inventory has increased to 176 homes.

That tells us conditions are not accelerating toward sellers right now. Instead, the market appears to be holding relatively steady.

What Is Happening With Simi Valley Home Prices?

The current median list price is $925,000, and the median asking price per square foot is $492.

Prices have not been moving significantly higher in recent weeks.

That fits with what we are seeing elsewhere in the data. The market remains in seller territory, but buyers appear willing to push back when they believe a property is priced too aggressively.

The fact that 42% of current listings have reduced their asking price is worth paying attention to.

For sellers, that is a reminder that the initial pricing strategy still matters.

For buyers, it means there may be opportunities among homes that have been sitting longer or have already adjusted their price.

How Long Are Homes Taking to Sell?

The current median days on market is 42 days.

That is not an especially slow market, but it is also not the kind of environment where every well-located home sells immediately.

Buyers have some time to compare properties, and sellers need to make a strong first impression.

Condition, presentation and pricing all become more important when buyers have additional inventory to choose from.

What Does Rising Inventory Mean?

Simi Valley inventory has increased to 176 single-family homes.

More inventory generally gives buyers additional choices.

That does not automatically mean Simi Valley has become a buyer’s market. The Market Action Index is still at 42, which keeps the city in a slight seller’s advantage.

But rising inventory is a trend we want to continue watching.

If inventory continues to build while buyer activity slows, the balance could shift.

If buyer activity strengthens again, the market could tighten quickly.

What Does This Mean for Sellers?

For someone thinking about selling in Simi Valley, the market is still favorable, but strategy matters.

A slight seller’s advantage is not the same thing as unlimited pricing power.

With 42% of listings showing price reductions, buyers are clearly paying attention to value.

The strongest approach is to look closely at:

• Recent neighborhood sales
• Current competing homes
• Property condition
• Days on market
• Price reductions
• Buyer activity within your specific price range

The goal is to enter the market in a position that attracts buyers rather than spending several weeks chasing the market down.

What Does This Mean for Buyers?

There are more choices than there were previously, and that can create opportunities.

The median home is taking 42 days to sell, and a large percentage of listings have already reduced their asking price.

That does not necessarily mean every seller is ready to negotiate aggressively.

But buyers should pay attention to homes that have been sitting longer, properties that have experienced price reductions, and situations where competition is limited.

What About Renting in Simi Valley?

The current median rent is $4,140 per month.

For someone comparing buying with renting, that number is worth considering alongside mortgage rates, property taxes, insurance, maintenance costs and how long you expect to own the property.

There is no single answer that works for everyone.

The Bottom Line

Simi Valley’s housing market is holding fairly steady.

The Market Action Index has eased slightly from 43 to 42, while inventory has increased to 176 homes.

The city remains in a Slight Seller’s Advantage, but price reductions on 42% of current listings show that buyers are still sensitive to value.

For sellers, pricing correctly matters.

For buyers, rising inventory and price reductions may create opportunities.

And as always, citywide numbers are only the starting point. What is happening in your specific Simi Valley neighborhood and price range can be very different.
