Rate/point options: All the combinations of interest rate and points that are offered on a particular program. On an adjustable rate mortgage, rates and points may also vary with the margin and interest rate cap.

Rate protection: Protection against the danger that rates will rise between the time a borrower applies for a mortgage loan and the time the loan closes. This protection can take the form of a "lock" where the rate and points are frozen at their initial levels until the loan closes; or a "cap" where the rates and points cannot rise from their initial levels but they can decline if market rates decline. In either case, the protection only runs for a specified period. If the loan is not closed within that period the protection expires and the borrower will either have to accept the terms quoted by the lender on new loans at that time, or start the shopping process over again.

Real Estate Settlement Procedures Act (RESPA): A consumer protection law that requires lenders to give borrowers advance notice of closing costs.

Required cash: The total cash required of the home buyer to close the transaction, including down payment, points and fixed dollar charges paid to the lender, any portion of the mortgage insurance premium that is paid upfront, and other settlement charges. These settlement charges may include title insurance, taxes, etc., and are shown on the Good Faith Estimate of settlement charges that the borrower receives.

Sale of Servicing: The sale of loan servicing rights.

Secondary Mortgage Market: A market where existing mortgages are bought and sold. The two largest players are the Federal National Mortgage Association or Fannie Mae, and the Federal Home Loan Mortgage Corporation or Freddie Mac. There are also individual mortgage conduits to the secondary market.

Servicing Fees: The compensation a lender receives from Fannie Mae or Freddie Mac for servicing loans which have been sold to them. The fee is usually calculated monthly based on the principal outstanding on each loan serviced.

Servicing Released: Sale of the rights to service a mortgage loan when the loan is sold in the secondary market.

Sub-servicing: An arrangement whereby the lender retains ownership of the servicing rights, but enters into an agreement with a mortgage servicer to perform the servicing function.

Subordinate financing: A second lien on the property securing the loan at the time of closing. This arises when there is a second lien on the property at the time the new loan is taken out, and the new loan does not pay it off.
