How Credit Affects Your Mortgage (Rates & Insurance), Loan Types, and a Real-World Lancaster Example

Disclaimer (not legal/financial advice): The info below is educational and based on typical guidelines. Loan pricing, mortgage insurance, and eligibility vary by lender and your personal profile. Always confirm details with a licensed lender before making decisions.


Why Your Credit Score Matters (a lot)

Your credit score doesn’t just influence whether you’re approved—it changes how much your mortgage costs every month.

  • Interest rate: Higher scores generally qualify for lower rates.

  • Mortgage insurance cost: Conventional PMI gets cheaper as scores rise (and disappears once you hit certain equity). FHA MIP is fixed by program, not score, but your rate still depends on credit.

  • Loan choices: Some programs (USDA, VA, FHA, conventional) will be more favorable than others depending on your credit, income, debt, and down payment.

Rule of thumb

Every 1.00% change in rate is roughly ~$68/month per $100,000 borrowed on a 30-year fixed. That adds up fast!

Mortgage Insurance 101 (PMI vs. MIP vs. No MI)

  • Conventional (PMI): Required if you put <20% down. Price varies by credit score and down payment percentage.

    • You can request removal at 80% LTV and it must auto-cancel at 78% LTV (Homeowners Protection Act), assuming on-time payments.

  • FHA (MIP): With 3.5% down, annual MIP is typically 0.55% of the loan amount and doesn’t drop off on most 30-year loans with ≤10% down. There’s also a 1.75% upfront premium (usually financed).

  • VA: No monthly MI. There’s a funding fee (often financed), but many eligible veterans with a qualifying disability rating get it waived.

  • USDA: No MI, but there’s a 1.00% upfront guarantee fee (usually financed) and a 0.35% annual fee (acts like cheap monthly MI). Income and location limits apply—much of Lancaster County outside city/boroughs is commonly eligible.


The Big Four Loan Types (Quick Guide)

  • Conventional: Great for solid credit and at least 3–5% down. PMI can be removed with equity. Best pricing as scores rise.

  • FHA: Ideal for modest credit or tighter debt-to-income. Low down payment (3.5%). MIP sticks around on most 30-year loans with ≤10% down.

  • VA: For eligible service members/veterans and some surviving spouses. $0 down, no monthly MI. Funding fee may be waived with a qualifying disability rating.

  • USDA: $0 down for eligible rural areas and income limits. Low monthly cost via the small annual fee. Great for qualified Lancaster County buyers outside the city core.

Takeaway: Going from the low-700s to the low-600s in credit can cost $600–$700+/mo on the same home once you factor in both rate and PMI.

FHA with 3.5% down

  • Base loan: $337,750

  • +1.75% upfront MIP (financed): $5,911 ⇒ total loan $343,661

  • 6.75% PI: $2,229/mo

  • Annual MIP 0.55% ≈ $155/mo initially

  • Total ≈ $2,384/mo (before taxes/insurance)

VA with 0% down (typical first-use, no waiver shown here)

  • Price $350,000 + 2.15% funding fee (financed) ⇒ loan $357,525

  • 6.75% PI: $2,319/mo

  • No monthly MI

  • Total ≈ $2,319/mo

If the VA funding fee is waived (qualifying disability), the loan would be $350,000 and payment drops accordingly.

USDA with 0% down (income/geography limits)

  • Price $350,000 + 1.00% upfront fee (financed) ⇒ loan $353,500

  • 6.75% PI: $2,293/mo

  • Annual fee 0.35% ≈ $102/mo

  • Total ≈ $2,395/mo

Bonus: Conventional with 20% down (no PMI)

  • Loan $280,000 at 6.75% ⇒ $1,816/mo (P&I only)

All figures are estimates. Real quotes depend on your exact credit profile, debts, income, assets, property type, and lender pricing on the day you lock.
