Selecting the mortgage type
You can select the mortgage type from the options below:
Conventional: Loan type not backed by government agency programs like VA or FHA.
FHA: Loan type backed by the Federal Housing Administration (FHA), offering low down payment loans and flexible credit requirements. Typically for first-time or lower-income buyers.
VA: Loan type backed by the U.S. Department of Veterans Affairs (VA), available to eligible veterans and active service members, often with no down payment required.
Points % and Lender credit/discount fields
Points %: Enter percentage as positive (discount points) or negative (lender credit). Example: -1% for a lender credit or +1% for discount points.
Lender credit or discount: Lender credit or discount is auto-calculated based on the points % entered.
Example: $300,000 base loan × -1.00% = $3,000 lender credit
$300,000 base loan × +1.00% = $3,000 discount
