PITI: Principal, Interest, Taxes, and Insurance: the four elements of a monthly mortgage payment; payments of principal and interest go directly towards repaying the loan while the portion that covers taxes and insurance (homeowner's and mortgage, if applicable) goes into an escrow account to cover the fees when they are due.

PITI Reserves: a cash amount that a borrower must have on hand after making a down payment and paying all closing costs for the purchase of a home. The principal, interest, taxes, and insurance (PITI) reserves must equal the amount that the borrower would have to pay for PITI for a predefined number of months.

Planned Unit Development (PUD): a development that is planned, and constructed as one entity. Generally, there are common features in the homes or lots governed by covenants attached to the deed. Most planned developments have common land and facilities owned and managed by the owner's or neighborhood association. Homeowners usually are required to participate in the association via a payment of annual dues.

Points: a point is equal to one percent of the principal amount of your mortgage. For example, if you get a mortgage for $95,000, one point means you pay $950 to the lender. Lenders frequently charge points in both fixed-rate and adjustable-rate mortgages in order to increase the yield on the mortgage and to cover loan closing costs. These points usually are collected at closing and may be paid by the borrower or the home seller, or may be split between them.

Pre-Approval: a lender commits to lend to a potential borrower a fixed loan amount based on a completed loan application, credit reports, debt, savings and has been reviewed by an underwriter. The commitment remains as long as the borrower still meets the qualification requirements at the time of purchase. This does not guaranty a loan until the property has passed inspections underwriting guidelines.

Prepayment: any amount paid to reduce the principal balance of a loan before the due date or payment in full of a mortgage. This can occur with the sale of the property, the pay off the loan in full, or a foreclosure. In each case, full payment occurs before the loan has been fully amortized.

Pre-Qualify: a lender informally determines the maximum amount an individual is eligible to borrow. This is not a guaranty of a loan.

Prepayment Penalty: a fee charged to a homeowner who pays one or more monthly payments before the due date. It can also apply to principal reduction payments.

Prime Rate: the interest rate that banks charge to preferred customers. Changes in the prime rate are publicized in the business media. Prime rate can be used as the basis for adjustable rate mortgages (ARMs) or home equity lines of credit. The prime rate also affects the current interest rates being offered at a particular point in time on fixed mortgages. Changes in the prime rate do not affect the interest on a fixed mortgage.

Principal: the amount of money borrowed to buy a house or the amount of the loan that has not been paid back to the lender. This does not include the interest paid to borrow that money. The principal balance is the amount owed on a loan at any given time. It is the original loan amount minus the total repayments of principal made.

Property Tax: a tax charged by local government and used to fund municipal services such as schools, police, or street maintenance. The amount of property tax is determined locally by a formula, usually based on a percent per $1,000 of assessed value of the property.
