What this includes
A US payment quote is principal and interest. Owner cost adds property tax, insurance, and PMI while the loan is above 80% of the price.
United States
The monthly number is not the payment.
Four planning tools for US buyers and owners: monthly PITI (with PMI when it applies), a price ceiling, refinance break-even, and closing cash from your Loan Estimate.
Mortgage
Principal and interest plus property tax, insurance, and PMI while the loan is above 80% of the price — the monthly number the payment quote leaves out. Extra principal is a first-class input.
Afford
The highest price at which owner cost is 28% of gross income, with how lenders in this market actually test it.
Refinance
Months to recover switching costs from a lower payment. Compare the break-even period with how long you expect to keep the new loan.
Closing costs
Transfer taxes and closing costs you enter from your Loan Estimate.
