Short answer
Possibly. A higher insurance premium increases the housing expense used in mortgage qualification, even if you pay the premium directly instead of through escrow. Your lender needs the updated quote and must recalculate your file. The result depends on income, other debts, loan program and underwriting. An earlier preapproval is not a promise that a higher payment will qualify.

What can change the answer?
A different property, loan amount, documented income or debt payment can change qualification. Increasing a deductible can change the premium, but it also changes the loss you would pay yourself and may affect lender acceptance. Discuss that tradeoff with the insurance professional and lender before selecting a policy.
Do not cancel insurance, omit a supplemental premium or open new credit to make the estimate look better. Ask your lender to compare the revised payment and cash to close against both underwriting requirements and the household budget. A payment that qualifies still needs to be comfortable for you.
Illustrative scenario: a quote changes the monthly payment
A buyer shopping in Placer County has $10,000 in qualifying gross monthly income and $500 in other monthly debt. The estimated housing payment, including an assumed $1,800 annual insurance premium, is $3,500. The actual quote is $4,800 per year. These are hypothetical planning figures, not local market averages, an insurance quote or an approved loan.
The annual increase is $3,000. Dividing by 12 adds $250 per month, so the housing estimate becomes $3,750. Total monthly debt rises from $4,000 to $4,250. Debt-to-income ratio rises from 40% to 42.5%: $4,250 divided by $10,000. Neither percentage by itself establishes eligibility.
Why the lender needs the complete quote
Fannie Mae's housing expense guidance includes homeowners and supplemental property insurance in the monthly housing expense. When multiple policies are needed, bring all premiums to the lender, not only the fire policy. Also identify taxes, association dues, mortgage insurance and subordinate financing so the estimate does not omit a recurring obligation.
Keep first-year cash needs separate from the ongoing monthly cost. Premiums paid before closing and initial escrow deposits can affect cash to close. Ask for a revised estimate rather than adding those amounts to the monthly payment a second time.

What to check next
Send the complete quote, effective date, policy conditions and any supplemental quote to the loan team. Ask: Has qualification been recalculated? Are the coverage and deductible acceptable? What changes in cash to close? Which conditions remain before closing? Keep the revised figures with your home-search budget.
