A large-mortgage payment: worked example
Illustrative assumptions, not a current rate offer: $1,200,000 purchase price, 20% down, a $960,000 loan, 6.5% fixed interest and 30 years.
- Principal and interest: $6,067.85 per month.
- Property taxes: $14,400/year, or $1,200/month.
- Homeowners insurance: $3,600/year, or $300/month.
- HOA: $150/month.
- Total modeled payment: $7,717.85/month.
- Down payment: $240,000. Closing costs entered at 2% of purchase price: $24,000. Modeled cash needed: $264,000.
The cash figure excludes prepaid items, initial escrow funding and lender reserve requirements. The payment excludes mortgage insurance, maintenance and other ownership costs. Actual costs must come from your lender and property estimates.
Does the loan amount make it jumbo?
Compare the loan amount with the applicable conforming limit for the property’s county, year and unit count. A high-cost county can have a higher limit; purchase price alone does not decide the classification. This calculator estimates costs and does not determine eligibility, underwriting approval or a lender’s product requirements.
