While national real estate commentary often centers on interest rates and affordability, Sheila Smith, Team Lead at RE/MAX Capital City, is watching different signals in Boise, Idaho: the pace of default notices and the number of homeowners nearing or crossing the 20% negative equity threshold. Smith reports a recent surge in default filings, which have risen from one or two per month to several pages — an early sign of stress she recalls from the 2008 to 2010 downturn.

“I’ve seen notice of defaults where there used to be one or two a month. Now we’ve got a couple of pages,” Smith says. Smith emphasizes that this does not yet signal a full-blown crisis, but it suggests that some homeowners are nearing distress.

The 20% Negative Equity Threshold

Smith points to a specific threshold: when homeowners lose more than 20% of their equity, the risk of distressed sales rises sharply. Historically, once equity falls below this level, short sales and foreclosures become more common, even among those who can still make their payments. The loss of the typical down payment, combined with the inability to sell without bringing cash to closing, often pushes owners to consider walking away.

“Once you’re more than 20% upside down, your chances of having to look at short sales or foreclosures go up,” Smith explains.

This 20% mark is significant because it often represents the initial investment for buyers with conventional financing. Falling below it means homeowners have lost their entire down payment. If they need to sell due to job loss, divorce, or relocation, they must either bring significant cash to closing or pursue a short sale. For many, this creates a clear choice between strategic default and taking a large financial hit.

Some Boise, Idaho, submarkets have already reached this point, Smith notes. Homeowners who bought at recent peaks now face 20% or greater price declines, especially when competing with aggressively priced new construction. While this group remains a minority, the psychological effects and potential for contagion are outsized compared to the actual number of distressed properties, Smith warns.

Rising Inventory Pressures Boise Prices

Inventory levels and supply-demand dynamics are more reliable indicators of market health than interest rate forecasts, Smith argues. Boise, Idaho, is approaching four to five months of inventory, nearing the six-month level typically associated with a balanced market. If inventory rises further, the market could tip into buyers’ territory, increasing downward pressure on prices and pushing more homeowners below the 20% equity threshold.

“What’s most important when understanding what might be coming is supply and demand. Economics drives everything — supply and demand are what will drive pricing,” Smith says.

Smith’s work shapes this perspective during the 2008 to 2010 downturn, when she specialized in short sales and saw how rising inventory can trigger a cycle of price declines. As inventory grows, homes sit on the market longer, leading to price reductions. These reductions push more owners underwater, increasing the number of distressed sales and feeding further inventory growth.

Boise’s inventory increase comes despite the rate-lock effect, where many homeowners with low mortgage rates are reluctant to sell. This suggests that inventory growth is driven by new construction or sellers with no choice but to list — groups that are typically more motivated to close, adding to downward price pressure.

Fear Can Accelerate a Downturn

Smith is especially wary of how fear and negative headlines can accelerate a downturn beyond what fundamentals justify. Smith recalls that during the 2008 to 2010 period, panic selling and fear-driven decisions contributed to a wave of distressed sales, even among those who could afford their mortgages.

“Even if it’s just a small portion of the market, it sends ripples,” Smith says. “People start fear-mongering and feeding off that, which is what happened in 2008. All this negative publicity got people panicking.”

Visible signs of distress, such as a rise in default notices, short sales, or foreclosures, often create a perception of crisis that can become self-fulfilling. Homeowners who might otherwise wait out a slow market choose to sell preemptively, adding to inventory and accelerating price declines. Buyers, expecting further drops, delay purchases, which further weakens demand.

During the last crisis, some homeowners walked away from their mortgages based solely on equity loss, not affordability, Smith notes. The perception that prices would keep falling drove decisions that didn’t always make financial sense.

Boise Market Remains Watchful

Smith sees the current situation as requiring vigilance but not yet showing widespread distress. Default notices are up, but they still represent a small share of total properties. Most Boise homeowners retain significant equity after years of appreciation, and the local economy remains strong, supported by employers like Micron and Boise State University.

However, Smith notes the market is flat and could tip into a buyer’s market if current trends persist. Such a shift would mark a sharp change from the seller’s market that has dominated Boise for more than a decade.

“If we tip past an even market, which we might this year because it is flat, I think that’s going to be concerning. I fear that can cause more damage than actual data,” Smith says.

Smith distinguishes between changes driven by fundamentals, such as employment or affordability, and those amplified by perception and fear. Even with strong job growth and manageable inventory, negative sentiment can trigger a sharper correction than economic data alone would predict.

Tracking Local Data Over Headlines

Smith relies on hard data at the local level rather than national forecasts or sentiment. Smith tracks inventory relative to historical norms, the pace of inventory changes, days on market, and distressed-sales indicators such as default notices and short-sale listings.

This approach reflects Smith’s experience that local data provides earlier warning signs than national commentary. By the time broader reports identify a downturn, local practitioners like Smith have often already seen the shift in their daily business.

The recent jump in default notices, from one or two per month to several pages, is the kind of early signal Smith watches closely. While the absolute numbers are still small, the rate of increase and direction of the trend offer important clues about rising stress before it appears in headline statistics.

Smith recognizes patterns, such as rising inventory, more distressed listings, and increasing days on market, that can quickly shift market psychology from confidence to anxiety. This emphasis on monitoring rather than predicting reflects a belief that turning points are clearer in hindsight. Still, that careful attention to local data allows agents and clients to respond sooner.

What the Next Months Reveal

The Boise market is at a critical juncture. Inventory is rising, and the number of homeowners at risk of negative equity is increasing in some submarkets. While most owners still have substantial equity and the local economy is strong, early signs of stress, such as the surge in default notices, warrant attention.

The next several months will reveal whether inventory continues to climb and whether more homeowners cross the 20% negative equity threshold. If so, Boise could see an uptick in distressed listings and further price declines, especially if negative sentiment takes hold. On the other hand, if employment remains solid and inventory growth slows, the market could avoid a more serious correction.

For now, Smith’s approach is to monitor the data closely and advise clients based on real-time local indicators rather than headlines or predictions. The lesson from the last downturn is clear: early signals matter, and market psychology can change quickly. By focusing on measurable trends and staying alert to shifts in supply, demand, and homeowner equity, Boise agents and buyers can position themselves to respond proactively, regardless of what broader forecasts may say.
