Technology has revolutionized the mortgage selection process, making rate comparisons a quick and easy first step. That said, it’s important to look beyond the initial rates and dig deeper into loan terms (the fine print), such as closing costs, hidden fees and down payment requirements. Some lenders will claim to charge “no origination fee,” but their online quote includes a hefty 2% “discount point” in the fine print. Another great resource when evaluating lenders is to read online reviews on Google, Yelp, Zillow or Facebook.
In simple terms, a mortgage is a loan in which your house functions as the collateral. The bank or mortgage lender loans you a large chunk of money (typically 80 percent of the price of the home), which you must pay back -- with interest -- over a set period of time. If you fail to pay back the loan, the lender can take your home through a legal process known as foreclosure.
Example – A $200,000 fixed-rate mortgage for 30 years (360 monthly payments) at an annual interest rate of 4.5% will have a monthly payment of approximately $1,013. (Taxes, insurance and escrow are additional and not included in this figure.) The annual interest rate is broken down into a monthly rate as follows: An annual rate of, say, 4.5% divided by 12 equals a monthly interest rate of 0.375%. Every month you’ll pay 0.375% interest on the amount you actually owe on the house.
When you apply for a mortgage, you'll need to document your income, employment situation, identity, and more, so it can be a good idea to start gathering the necessary documentation before you walk into a lender's office. This isn't an exhaustive list, but you should locate your last couple of tax returns, bank and brokerage statements, pay stubs, W-2s, driver's license, Social Security card, marriage license (if applicable), and contact numbers for your employer's HR department. Here's a more comprehensive list that can help you determine what you'll need.
You can opt for an interest-only mortgage where, as the name suggests, you just pay the interest every month. However, you’ll have to pay off the capital eventually so it’s important to have a repayment plan in place. The number of lenders offering interest-only mortgages has reduced over the last few years because there are concerns that many of those who have them have no repayment plan in place and could be left unable to pay back the capital at the end of the term. 
Include PITI (principal, interest, taxes and insurance) in your budget. Mortgage calculators will show you how much you'll pay toward principal and interest every month. Remember that you'll also have to pay property taxes and homeowners insurance. Some financial institutions will require you to contribute these funds monthly along with your principal and interest payment. Be sure to talk to your lender to understand what will be included in your monthly payment.
Hybrid Adjustable Rate Mortgages (ARMs): Mortgages that have fixed payments for a few years, and then turn into adjustable loans. Some are called 2/28 or 3/27 hybrid ARMs: the first number refers to the years the loan has a fixed rate and the second number refers to the years the loan has an adjustable rate. Others are 5/1 or 3/1 hybrid ARMs: the first number refers to the years the loan has a fixed rate, and the second number refers to how often the rate changes. In a 3/1 hybrid ARM, for example, the interest rate is fixed for three years, then adjusts every year thereafter.
