Things to Know
Essential concepts for understanding your results
Key FactorsWhat factors most affect your mortgage costs?
The four inputs with the largest impact: loan amount (every $10,000 adds ~$63/month at 6.5%), interest rate (0.5% change = $85-95/month on $300K), loan term (15-year saves $200K+ in interest but has 40-50% higher payments), and down payment (20% eliminates PMI, saving $100-300/month). Small improvements in any of these — especially rate — compound into massive savings over the loan's life.
Total CostWhy should you focus on total cost, not monthly payment?
A lower monthly payment often masks a higher total cost. Extending from 15 to 30 years cuts payments by 40% but doubles total interest. On $300,000: 15-year total = $455,000, 30-year total = $683,000. Similarly, a small rate difference (6.5% vs 7.0%) costs $35,000 over 30 years. Always compare total cost over the full term alongside monthly payment — the true cost is what leaves your pocket over the entire loan life.
PreparationHow can you improve your mortgage terms before applying?
Three high-impact actions: improve credit score (each 20-point gain saves 0.125-0.25% on rate — worth $15,000-30,000 over 30 years), reduce DTI (pay off small debts to lower your ratio below 36%), and increase down payment (reaching 20% eliminates PMI, saving $100-300/month). Spend 3-6 months optimizing these before applying — the investment of time produces returns measured in tens of thousands of dollars.
Jumbo Mortgage Calculator: Rates and Payments for High-Value Homes
A jumbo mortgage exceeds the applicable conforming loan limit set by the Federal Housing Finance Agency (FHFA). For a one-unit property in 2026, the national baseline is $832,750 and the high-cost ceiling is $1,249,125. County, unit-count, and special-area rules determine the exact threshold. Jumbo loans are not eligible for acquisition by Fannie Mae or Freddie Mac, so underwriting and pricing are lender-specific.
| Feature | Conforming Loan | Jumbo Loan |
|---|---|---|
| 2026 one-unit baseline | $832,750 | Above the applicable limit |
| Down payment | 3-20% | 10-20% (some 5% programs) |
| Credit score | 620+ | 700+ (often 720+) |
| DTI max | 45-50% | 38-43% |
| Pricing | Varies by lender and borrower | Varies by lender and borrower |
| Cash reserves | 0-2 months | 6-12 months |
Illustration: A $1,125,000 home with 20% down produces a $900,000 loan, which is above the 2026 one-unit baseline but may be within a higher county limit. At an assumed 7.0% for 30 years, principal and interest are about $5,988 per month. Verify the property-specific limit and compare lender quotes before treating the loan as jumbo.
Qualifying for a Jumbo Mortgage
Credit score: 700 minimum at most lenders, 720+ for the best rates. A 20-point improvement (700→720) can save 0.25% on the rate — $167/month ($60,000 over 30 years) on an $800,000 loan.
Cash reserves: Most jumbo lenders require 6-12 months of mortgage payments in liquid reserves after closing. On a $5,322/month payment: $31,932-$63,864 in reserves beyond your down payment and closing costs. Total cash needed: $200,000 down + $25,000 closing + $45,000 reserves = $270,000 minimum.
Debt-to-income ratio: Jumbo lenders typically cap DTI at 38-43% (vs 45-50% for conforming). On a $5,322/month payment: your total monthly debt payments (mortgage + car + student loans + credit cards) should not exceed $7,500-$8,200 on approximately $200,000+ annual income.
