Quick Answer:  An underwater mortgage occurs when a homeowner owes more on their mortgage than their home is currently worth. It is also referred to as an “upside-down mortgage.” According to ATTOM, approximately 3.2% of U.S. mortgaged homes are seriously underwater, representing about 813,000 homeowners. While most homeowners still have significant equity, recent buyers in markets where home prices have softened are more likely to experience negative equity. For real estate professionals, tools like PropStream's Upside Down Lead List can help identify homeowners who may benefit from guidance before financial challenges escalate.

Research shows that 3.2% of mortgaged homes are seriously underwater

Although the vast majority of U.S. homeowners continue to hold significant equity, negative equity is beginning to increase after several years of rapid home price appreciation. According to ATTOM Data, approximately 3.2% of mortgaged homes are seriously underwater, up from 2.7% a year ago. While this remains well below levels seen during the Great Recession, certain regional housing markets are experiencing growing pressure as home prices soften, affordability challenges persist, and borrowing costs remain elevated.

For real estate professionals, these trends represent more than just market statistics. They can signal opportunities to educate homeowners, provide solutions, and connect with those who may need guidance before financial challenges become more severe.

Key Statistics

Metric Current Value
Seriously underwater mortgages 3.2% of mortgaged homes
One year ago 2.7%
Estimated underwater borrowers Approximately 813,000 homeowners
Annual increase in underwater borrowers 44%
Total homeowner equity $18 trillion (record high)
Homeowners with tappable equity 47.5 million

Key Takeaways:

  • Recent buyers with low down payment loans are generally the most vulnerable to negative equity when home prices decline.
  • Rising negative equity may create opportunities for real estate professionals to educate and assist homeowners before financial challenges escalate.
  • PropStream's Upside Down Lead List helps agents and investors identify properties that may have negative equity, making it easier to connect with homeowners who could benefit from professional guidance.

What Is an Underwater Mortgage?

An underwater mortgage—also called negative equity or upside down—occurs when a homeowner owes more on their mortgage than their home is currently worth.


For example:

  • Current home value: $350,000
  • Remaining mortgage balance: $375,000

In this example, the homeowner has $25,000 in negative equity.


Being underwater doesn't automatically mean a homeowner is in financial trouble. However, it can make it more difficult to refinance, sell the home, or relocate without bringing additional funds to closing.

Why Are Underwater Mortgages Increasing?

Several factors are contributing to the recent rise in negative equity.

Home Prices Have Softened in Some Markets

Many housing markets experienced extraordinary appreciation between 2020 and 2022. As inventory has increased and affordability has weakened, prices in some regions have begun to level off or decline.

Homeowners who purchased near peak pricing have had less time to build equity, making them more vulnerable to market corrections.

Mortgage Rates Remain Elevated

Mortgage rates continue to remain well above the historic lows seen during the pandemic. Higher borrowing costs reduce affordability, limiting buyer demand and putting downward pressure on home prices in some markets.

Low Down Payment Loans Increase Risk

Many underwater homeowners purchased using FHA, VA, or other low-down payment financing programs. While these loans expand access to homeownership, they also leave buyers with less equity at closing. Even modest declines in property values can result in negative equity.

Rising Homeownership Costs

Increasing homeowners' insurance premiums, property taxes, maintenance expenses, and other ownership costs have added financial pressure for many households. While these expenses do not directly create negative equity, they can make it more difficult for homeowners to navigate changing market conditions.

Where Are Underwater Mortgages Most Common?

Negative equity is not evenly distributed across the country.

States experiencing some of the highest concentrations of underwater properties include:

  • Texas (351,247 underwater properties)
  • Florida (292,488 underwater properties)
  • Louisiana (111,596 underwater properties)
  • Minnesota (58,513 underwater properties)
  • Iowa (53,421 underwater properties)
  • Arkansas (37,113 underwater properties)
  • Mississippi (26,541 underwater properties)

*Data on underwater (upside-down) properties by state was sourced from PropStream's Upside Down Lead List. The figures reflect the data available when this report was created. Because property records and market conditions are continuously updated, these totals may change over time, and current results may differ from those shown in this report.

Many of these markets experienced rapid appreciation during the pandemic, followed by increasing inventory and moderating buyer demand.

Conversely, many Northeastern markets and areas with a tighter housing supply have generally maintained stronger homeowner equity.

Why Today's Market Is Different From 2008

Although underwater mortgages are increasing, today's housing market is fundamentally different from the conditions that contributed to the Great Recession.

2008 Housing Crisis Today's Market
Widespread speculative lending Stricter lending standards
High-risk mortgage products common Fixed-rate mortgages dominate
Millions of underwater homeowners Approximately 813,000 underwater borrowers
Broad negative equity nationwide Record $18 trillion in homeowner equity
Weak homeowner balance sheets Most homeowners still have significant equity

Today's increase in negative equity is largely concentrated among more recent buyers in markets where prices have softened, rather than across the entire housing market.

The Bigger Picture

One of the most notable aspects of today's housing market is that two seemingly opposite trends are occurring simultaneously.

Overall, homeowner equity has reached a record $18 trillion, according to ICE Mortgage Monitor, yet the number of underwater borrowers has begun to increase.

This reflects a growing divide between longtime homeowners, who have accumulated significant equity over many years, and recent buyers, who may be more susceptible to changing market conditions.

How This Could Affect the Housing Market

If negative equity continues to rise, several trends could emerge.

Homeowners who owe more than their homes are worth may postpone selling because the proceeds from a sale would not fully satisfy their mortgage balance.

Unexpected life events such as job loss, divorce, relocation, or rising housing expenses become more difficult to navigate without available home equity.

Some homeowners may begin considering loan modifications, short sales, or selling before their financial situation worsens.

What to Watch Going Forward

Several economic indicators will influence whether underwater mortgage rates continue to rise over the coming year, including:

  • Home price appreciation
  • Mortgage interest rates
  • Housing inventory levels
  • Employment trends
  • Foreclosure activity
  • Regional migration patterns

If mortgage rates remain elevated while home prices continue softening in certain markets, additional homeowners may find themselves underwater. Conversely, stronger home price growth or lower borrowing costs could help stabilize homeowner equity.

How Real Estate Professionals Can Help

For agents and investors, rising negative equity is more than a housing statistic. It can identify homeowners who may benefit from professional guidance before their situation becomes more challenging.

Some homeowners may not realize they have options beyond waiting for the market to recover. Others may need assistance understanding whether selling, negotiating with their lender, refinancing, or pursuing a short sale makes the most sense for their circumstances.

Reaching homeowners early gives real estate professionals an opportunity to educate, provide resources, and help homeowners evaluate their available options before financial challenges become more severe.

Frequently Asked Questions (FAQs)

What is an underwater mortgage?

An underwater mortgage—also called negative equity or upside down—occurs when a homeowner owes more on their mortgage than the home's current market value. This often happens after home values decline or when a buyer purchases with a small down payment and prices fall shortly afterward.

How common are underwater mortgages in the United States?

According to ATTOM Data, approximately 3.2% of mortgaged homes are currently considered seriously underwater. While this represents an increase from last year, the overwhelming majority of U.S. homeowners still have positive equity.

What causes a homeowner to become underwater?

Several factors can contribute to negative equity, including declining home prices, purchasing with a low down payment, market corrections after rapid appreciation, borrowing against home equity, or paying down mortgage principal more slowly than property values decline.

Can someone sell a home if they're underwater?

Yes. Depending on the homeowner's financial situation, options may include bringing funds to closing, negotiating a short sale with the lender, or waiting until additional equity is built. Available solutions vary based on individual circumstances and lender requirements.

Does an underwater mortgage automatically lead to foreclosure?

No. Many homeowners with negative equity continue making their mortgage payments on time. Foreclosure generally occurs when borrowers are unable to meet their loan obligations—not simply because they owe more than the home is worth.

Which homeowners are most likely to have an underwater mortgage?

Recent buyers who purchased near peak home prices with low down payment financing are generally more susceptible to negative equity if home values decline. Market conditions vary considerably by location.

How can real estate professionals identify homeowners with negative equity?

Aggregated property data platforms can estimate whether a property's outstanding loan balance exceeds its estimated market value. For example, PropStream's Upside Down Lead List helps agents and investors identify properties that may have negative equity and combine those results with additional filters such as pre-foreclosures, tax delinquencies, ownership length, and property characteristics.

How can PropStream help find these opportunities?
