Glossary of terms

Desired mortgage amount

The amount a borrower agrees to repay, as set forth in the loan contract.

Monthly housing expenses

Monthly outlay that includes monthly mortgage payment plus additional costs like property taxes and homeowners insurance, as well as other potentially applicable costs like mortgage insurance, flood insurance, homeowners association or co-op fees, or special tax assessments.

Monthly liabilities

Amounts of money that you owe to another person or entity. Liabilities can be short-term like credit card payments or longer-term like car loans or mortgages.

Monthly housing payment

A mortgage payment that includes PITI (principal, interest, taxes, insurance).

Maximum principle and interest

Calculated by subtracting your monthly taxes and insurance from your monthly PITI payment to calculate the maximum principle and interest (PI) payment to determine the mortgage amount that you could qualify for.

Start interest rates

The introductory interest rate, also known as the teaser rate or start rate, on an adjustable or floating-rate loan. It is usually lower than most other interest rates and often stays consistent within a specific time frame only.

The term in years

Mortgage terms aren’t limited to 30 and 15 years. Plenty of buyers prefer other options like 10-year, 20-year, 25-year, 40-year, and even five-year terms, based on their monthly income and budgetary goals.

Real estate taxes

Charged on immovable property, including land and structures that are permanently attached to the ground, such as a house or building. When you buy a home, you must pay real estate taxes, also known as property taxes, directly to your local tax assessor or indirectly as part of your monthly mortgage payment.

Hazard insurance

Insurance coverage for the structure of a home.

Association dues or fees

Required by some condominiums and neighborhoods as part of a homeowners’ association (HOA). Dues are typically paid directly to the homeowners’ association (HOA) and are not included in the payment you make to your mortgage servicer.

Monthly PMI

Stands for private mortgage insurance, which is a type of mortgage insurance you could be required to pay for if you have a conventional loan. PMI is typically required when you obtain a conventional mortgage and make a down payment of less than 20 percent of a home’s purchase price.
