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 conforming loan limit set by the Federal Housing Finance Agency (FHFA) — $766,550 in most areas for 2026 (higher in designated high-cost areas: up to $1,149,825 in places like San Francisco, NYC, and parts of Hawaii). Because jumbo loans cannot be purchased by Fannie Mae or Freddie Mac, they carry stricter requirements and traditionally slightly higher rates.
| Feature | Conforming Loan | Jumbo Loan |
|---|---|---|
| 2026 loan limit | $766,550 | Above $766,550 |
| Down payment | 3-20% | 10-20% (some 5% programs) |
| Credit score | 620+ | 700+ (often 720+) |
| DTI max | 45-50% | 38-43% |
| Rate | 6.5-7.5% | 6.5-7.8% (gap narrowing) |
| Cash reserves | 0-2 months | 6-12 months |
Example: $1,000,000 home with 20% down = $800,000 jumbo loan at 7.0% for 30 years. Monthly payment: $5,322 (P&I). Total interest over 30 years: $1,116,000. With a 15-year term at 6.5%: $6,966/month, $453,880 total interest — saving $662,000 but requiring $1,644 more per month.
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.
