Term in years
The number of years over which you will repay this loan. The most common mortgage terms are 15 years and 30 years.

Loan origination rate
The percentage the lending institution charges for its origination fee. 1% for a $100,000 home equals $1,000.

Number of points paid
The total number of points paid to reduce the interest rate of your mortgage. Each point costs 1% of your mortgage balance.

Other closing costs
Estimate of all other closing costs for this loan. This should include filing fees, appraiser fees and any other miscellaneous fees paid.

Monthly PMI payment
Monthly cost of Principal Mortgage Insurance (PMI). For loans secured with less than 20% down, PMI is estimated at 0.5% of your loan balance each year. Monthly PMI is calculated by multiplying your starting loan balance by this percent and dividing by 12. When the equity in your home exceeds the percentage required for PMI, your PMI payment drops to zero. Please note that this is only an estimate of your actual PMI. The amount you may be required to pay may be higher or lower than our estimate.

Monthly PI payment
Monthly principal and interest payment.

Total for down payment
Total funds remaining, after closing costs, for down payment.

Limit down payment
Limit your down payment to percentage required to eliminate the need for PMI payments. Even if you have more cash on hand than required for closing costs checking this box will limit your down payment to the minimum amount required to forego PMI.
