Home buyers are often focused on mortgage rates, home prices, and credit requirements. But another factor that’s complicating homeownership is rising home insurance costs. As natural disasters grow more frequent and rebuilding costs climb, homeowners’ insurance has become a major factor in mortgage approvals. Lenders now scrutinize insurance costs more closely than ever, and for many buyers, these rising premiums are the tipping point between approval and denial.

This article explores how rising home insurance costs are impacting mortgage approvals, why it matters to buyers and lenders, and what you can do to manage this evolving landscape.

The Surge in Home Insurance Premiums

Home insurance premiums have skyrocketed across the US, with new policies increasing by 9.3% in the first half of 2025 alone. Since 2022, premiums have surged by 45%, while coverage values have grown less than 12%. In some regions, homeowners are now spending more than half of their monthly mortgage payment on insurance and taxes combined.

Key Drivers of Rising Costs:

  • Climate Change: More frequent and severe natural disasters like hurricanes, wildfires, and tornadoes have led to higher claims and increased risk.
  • Material Costs: Federal tariffs on building materials such as copper, steel, and aluminum have raised the cost of home repairs and replacements.
  • Reinsurance Expenses: Insurance companies are paying more for reinsurance, which protects them from catastrophic losses, and these costs are passed down to consumers.
  • Litigation and Fraud: Legal changes and increased fraud have made claims more expensive to process, further driving up premiums.

How Do Insurance Costs Affect Mortgage Approvals?

When lenders evaluate a mortgage application, they consider the total monthly housing expense, known as PITI (Principal, Interest, Taxes, and Insurance). Rising insurance premiums inflate this figure, which can push a borrower’s debt-to-income (DTI) ratio beyond acceptable limits.

Why It Matters:

  • Higher PITI = Lower Affordability: If insurance costs are too high, the borrower may no longer qualify for the loan amount they need.
  • DTI Ratio Thresholds: Most lenders require a DTI ratio below 43%. Increased insurance premiums can cause borrowers to exceed this limit.
  • Loan Denials or Reduced Approval Amounts: Lenders may deny applications or approve smaller loans, forcing buyers to reconsider their budget or delay their purchase.

How Rising Home Insurance Costs Erode Borrowing Power Over Time

Below is a chart illustrating how average annual home insurance premiums have climbed since 2010 — and how those rising costs have steadily reduced the amount buyers qualify for when seeking mortgage pre-approvals.

Year Avg. Annual Mortgage Insurance Premium Borrower Pre-Approval Power (Based on 43% DTI)
2010 $900 $450,000
2015 $1,050 $440,000
2018 $1,250 $425,000
2020 $1,450 $410,000
2022 $1,800 $390,000
2023 $2,050 $375,000
2024 $2,250 $365,000
2025 $2,450 $350,000

What the chart shows:

  • Premiums are up ~172% since 2010.
  • Borrower buying power dropped by ~$100,000 — solely due to rising insurance costs pushing DTI ratios higher.

Regional Disparities in Insurance Costs Across The Pacific Northwest

The impact of rising insurance costs varies widely across the country. States prone to natural disasters, such as California and Colorado, have seen the steepest increases.

Examples:

  • Washington: Rising homeowners’ insurance premiums are driven by increased wildfire activity, flooding risks from heavy rainfall, and seismic concerns due to the state’s location along major fault lines.
  • California: Wildfire zones have become nearly uninsurable in some areas, forcing buyers to seek coverage through the state’s FAIR Plan.
  • Colorado: Tornadoes and hailstorms have led to double-digit premium hikes, especially in regions where “Tornado Alley” is shifting eastward.
  • Idaho: Rising homeowners’ insurance premiums are largely driven by an increase in wildfires and flood risks, which have made properties in forested and high-risk areas more expensive and difficult to insure.
  • Oregon: Increasing wildfire risks, especially in rural and forested areas, along with flooding concerns in regions near rivers and coastal zones are driving insurance rates up.

These regional disparities make it harder for buyers in high-risk areas to secure affordable mortgages, even if their credit and income are strong.

Lender Responses to Rising Insurance Costs

Mortgage companies are adapting their underwriting practices to account for insurance volatility. Some are tightening approval criteria, while others are requiring additional documentation or higher reserves.

Common Adjustments:

  • Stricter DTI Limits: Lenders may lower the maximum allowable DTI to offset rising insurance costs.
  • Mandatory Insurance Quotes: Borrowers are often required to provide insurance quotes during the mortgage pre-approval process.
  • Property Feature Reviews: Homes with older roofs, flat designs, or outdated systems may be considered high-risk, affecting both insurance and loan eligibility.
  • Escrow Adjustments: Lenders may increase escrow requirements to ensure insurance premiums are covered.

What Can Home Buyers Do?

If you’re planning to buy a home in today’s market, understanding how insurance affects your mortgage approval is essential. Here are some proactive steps to take:

1. Get Insurance Quotes Early

Before making an offer, request quotes from multiple insurers. This helps you estimate your monthly costs and avoid surprises during underwriting.

2. Factor Insurance Into Your Budget

Don’t just focus on the mortgage payment — include taxes and insurance in your affordability calculations.

3. Choose Properties Wisely

Homes with newer roofs, updated systems, and low-risk locations tend to have lower insurance premiums. Avoid properties with features that insurers consider high-risk.

4. Consider Excess & Surplus Lines

In high-risk areas, traditional insurers may decline coverage. Excess & Surplus (E&S) carriers offer alternatives, though often at higher costs.

The Broader Impact on Housing Affordability

Over recent years, housing affordability has been very tight, driven by high prices and rates. Now, escalating home insurance adds another layer of pressure.

Homebuyers Are Being Priced Out

Rising premiums reduce purchasing power. Even a slight monthly increase in insurance costs can reduce a buyer’s approved loan amount by thousands of dollars, depending on their DTI and interest rate.

Homeownership Gap Widening

First-time and moderate-income buyers are hit hardest, as they typically have tighter budgets and less flexibility to absorb unexpected costs.

Impact on Real Estate Markets

In high-risk regions, homes become harder to sell if insurance is unaffordable or unavailable, dampening local market activity and property values.

FAQs

How do rising insurance costs affect mortgage approvals?

Higher premiums increase the total monthly housing expense, which can push a borrower’s debt-to-income ratio beyond lender limits, jeopardizing approval.

What is included in the monthly housing expense calculation?

Lenders calculate housing costs using PITI — Principal, Interest, Taxes, and Insurance — so higher insurance directly increases this figure.

Can high insurance premiums cause a mortgage denial?

Yes. If the total monthly housing cost exceeds what the borrower can afford under lender guidelines, the mortgage may be denied.

Are certain regions more affected by rising insurance costs?

Yes. States like California and Colorado face higher premiums due to wildfires, earthquakes, and severe weather risks.

Do lenders require proof of insurance before closing?

Yes. Lenders need confirmation of active homeowners’ insurance to protect the property, which serves as collateral for the loan.

Can I shop around for cheaper insurance to improve approval chances?

Yes. Comparing quotes from multiple insurers can help lower your monthly costs and improve your DTI ratio.

Do older homes have higher insurance costs?

Often, yes. Homes with outdated systems, older roofs, or located in high-risk zones typically cost more to insure.

Can rising insurance costs delay mortgage closings?

They can. If insurance quotes come in higher than expected or coverage is hard to secure, it may delay final approval and closing.

Can I use a higher deductible to lower my premium?

Yes, choosing a higher deductible can reduce your monthly premium, but it also means more out-of-pocket costs if you file a claim.

Can insurance costs affect escrow requirements?

Yes. Lenders may increase escrow contributions to cover higher premiums, which raises your monthly mortgage payment.

What can I do to prepare for insurance-related mortgage challenges?

Get quotes early, factor insurance into your budget, choose low-risk properties, and work with professionals who understand regional insurance trends.

Final Thoughts

Rising home insurance costs are no longer just a budgeting concern — they’re a critical factor in mortgage approvals across the US. As premiums climb, lenders are tightening standards, and buyers must be more strategic than ever. Whether you’re a first-time home buyer or a seasoned investor, understanding the insurance landscape is key to securing financing and protecting your investment.
