Broker: An independent mortgage professional that oversees the entire home loan process.

Lender: The business entity providing and funding the home loan.

Processor: Prepares your loan for underwriting. The processor makes certain your income is properly documented and verified, the appraisal is being performed, and title and escrow are opened.

Escrow: Works with title to certify payoff demands for all existing liens. Escrow is an independent group which disburses monies to all parties in the loan transaction and ensures full payment.

Title: Ensures both the borrower and the lender have a clean title on the home, guaranteeing to both parties there are no mistaken liens and that all existing liens on the home are scheduled to be paid and removed.

Underwriters: Make the decision to approve or deny the loan. Hired by the lender, their job is to review all aspects of the loan based on the lender's approval guidelines.

Automated Underwriting: A computer generated loan approval. This automated process only takes minutes and is the quickest path to approval.

ARM: Adjustable Rate Mortgage. An ARM has a fixed rate for a specified amount of time. After the initial term, the loan becomes adjustable and the rate can fluctuate depending on market conditions. ARM payments are initially lower than fixed rate payments. This is an excellent option for people with damaged credit, those who plan to sell their homes short term or who simply want to save money on their monthly payment.

DTI: Debt to Income Ratio or your total monthly debt in relation to your gross monthly income. For example if you have $2,500 in total monthly debts with a total income of $5,000, your DTI is 50%. The higher the DTI, the higher the lender's risk and 50% is typically the maximum allowable DTI.

Equity ? The amount of vested or owned interest in your property. Subtract the total balance owed on the property from the appraised value to determine your equity.

FICO Scores: Most lenders use the FICO scoring system to qualify borrowers. The FICO score is a number assigned from each of the three main credit repositories (Experian, Trans-Union, and Equifax). This number is calculated based on your complete credit profile and takes into account late payments, balances on trade lines, inquiries for additional credit, judgments, bankruptcies, total debt, length of credit history, and more. The lower the FICO score, the higher the lender's risk.

LTV: Loan to Value Ratio. For example: a loan amount of $75,000 on a home valued at $100,000 equals an LTV of 75%. Your equity would equal $25,000, or 25%. The higher the LTV ratio, the higher the lender's risk.

Stated Income: Your own statement of income on the application versus income that can be independently verified. Use of stated income is an excellent option for self-employed individuals or those with hard to prove income.

Getting a mortgage for a home purchase can be stressful. If you understand the lingo being used, you will find it less so.
