Buying a Home...1, 2, 3: Borrowing Basics

The whole process of getting a mortgage can be confusing. This section will give you an idea of what questions a lender will ask when you apply for a mortgage loan. It will also give you some ideas of the questions you should be asking lenders when you are shopping for a mortgage.


What is a mortgage loan?

A mortgage requires you to pledge your home as the lender’s security for repayment of your loan. The lender agrees to hold the title to your property (or in some states, to hold a lien on your title) until you have paid back your loan plus interest. If you do not repay your mortgage loan, the lender has the right to take possession of your house and sell it in order to satisfy the mortgage debt.


Principal and Interest

All mortgages have two features in common. The first feature is the mortgage principal, which is the actual amount of money you borrow. So, if you take out a $70,000 mortgage, your mortgage principal is $70,000. The second feature is the mortgage interest, which is the money you pay for use of the money you borrow.

How much interest you pay over the life of your loan depends on a number of factors—which you will learn about shortly. The interest you pay on your mortgage can be deducted from your taxes, which is one of the many benefits of homeownership.


Amortization

Young Couple's First HomeOver time, you will repay your mortgage gradually through regular, monthly payments of principal and interest. The amounts of these payments are calculated to let you own your home debt-free at the end of a fixed period of time. During the first few years, most of your payments will be applied toward the interest you owe. During the final years of your loan, your payment amounts will be applied almost exclusively to the remaining principal. This type of repayment method is called amortization. When you sell your home, you will be required to pay back any remaining principal balance due on your mortgage loan to your lender.

Keep in mind that, in addition to your mortgage payment, other expenses such as private mortgage insurance (PMI), property taxes and insurance may also due each month.


The four factors that affect your mortgage payments

They are:
  • the size of your down payment,
  • the amount of your mortgage,
  • your mortgage interest rate, and
  • the repayment term of the mortgage loan you choose.

For example, your down payment will reduce the amount you’ll need to borrow. So, the more cash you put down, the smaller the size of your loan. And the smaller your mortgage payments will be.


Down Payment

In the past, mortgage lenders expected home buyers to make a down payment amounting to at least 20 percent of the purchase price of the home. Today, however, most lenders will offer you mortgage loans with as little as 5 percent down. Some may even offer 3 percent down, or even zero percent down.

How much money do you feel comfortable applying to your down payment? Before you decide, you’ll need to consider closing costs, moving expenses, home furnishing expenses, and any needed upcoming “big ticket” items. And remember, lenders may require you to have two months of mortgage payments in reserve when you go to closing.

Lenders often view mortgages with larger down payments as more secure because you have more of your own money invested in the property. Therefore, putting less than 20 percent down often means you will be required to purchase private mortgage insurance. Private mortgage insurance protects the lending institution in case you fail to make payments on your mortgage. Its cost will be added to your monthly mortgage payments and to your closing costs.

Some types of mortgages for which you put less than 20 percent down do not require private mortgage insurance. These include loans insured by the federal government such as an FHA loan or a VA loan. Your state may also offer special mortgages for low- and moderate-income home buyers that use state-sponsored mortgage insurance programs.


Amount of Your Mortgage

With a maximum down payment in mind, you now can figure out the next factor that will affect your monthly mortgage payments—the amount you borrow.

Grandfather and GrandsonYour actual mortgage payments will depend in large part on the amount you borrow—your mortgage principal. Your income and your debts are the most important factors for determining how large a mortgage you will be able to get. If you are buying a house with someone else, you should consider your co-purchaser’s earnings and existing debts as well. (If you apply for a loan with somebody else, you and your co-borrower are both legally responsible for repayment of the mortgage).

Lenders use two guidelines to determine the amount of money they will lend. The first guideline says that a household should spend no more than 28 percent of its gross monthly income (income before taxes) on monthly housing expenses. Monthly housing expenses include mortgage principal and interest, hazard insurance, real estate taxes, and private mortgage insurance (if applicable). Lenders do not include monthly utility bills in your monthly housing expense ratio.

The second guideline says that monthly housing expenses and other long-term debts combined generally should not be more than 36 percent of total monthly income. That means that your monthly mortgage principal and interest payments, real estate taxes, hazard insurance, car loan, credit card payments, and other long-term debts combined generally may not exceed 36 percent of your gross monthly income.

These ratios (28 percent of total income for housing expenses and 36 percent for total debt) are flexible guidelines. If you have a consistent record of paying rent that is very close in amount to your proposed monthly mortgage payments or you make a large down payment, you may be able to use somewhat higher ratios. What’s more, some lenders offer special loan programs for lower-and moderate-income home buyers that allow as much as 33 percent of their gross monthly income to be used toward housing expenses and 38 percent for total debt.

One easy way to find out how much you can afford to borrow is to get pre-qualified by a mortgage lender. Many lenders will be happy to tell you how large a mortgage they might offer you. At the prequalification stage, you do not need to obligate yourself by paying an application fee and actually applying for the mortgage. However, keep in mind that lender pre-qualifications are only “ballpark” ranges of your buying power and don’t obligate the lender to approve your loan.


Interest rate

Getting the best interest rate is a very important part of your mortgage shopping decision. The lower your interest rate, the lower your monthly payments. With a lower rates, you’ll have greater buying power because you can borrow more money for approximately the same monthly payment.

Here are some points to keep in mind when you compare interest rates among loans:

  • Shorter term loans offer lower interest rates. Keep in mind that each type of mortgage loan may carry a different interest rate. As a general rule, the shorter the term of the loan, the lower the interest rate you will pay. So, a 15-year fixed-rate mortgage usually has a lower interest rate than a 30-year fixed-rate mortgage.
  • A fixed versus an adjustable interest rate. Also keep in mind that you can choose a mortgage with an interest rate that is fixed for the entire term of the loan, or an interest rate that adjusts during the loan term. A fixed-rate loan gives you the security of knowing that your interest rate will never change during the entire term of the loan. An adjustable-rate mortgage loan (called an ARM) has an interest rate that will vary during the life of the loan, with the possibility of both increases and decreases to the interest rate and consequently to your mortgage payment. An ARM frequently offers a lower initial interest rate than a fixed rate mortgage. However, when comparing interest rates between ARMs and fixed-rate mortgages, you need to know the adjustable rate mortgage’s interest rate caps. There is a cap or limit for how much the interest rate can increase over the life of the loan, and a cap for how much the interest rate can increase at each adjustment date. These caps tell you the maximum interest rate you could be required to pay during each adjustment period and over the life of the loan.
  • Paying discount “points” can lower your interest rate. In the special vocabulary of mortgage lending, “points” is a difficult term for many home buyers to understand. “Points” are often used to describe a type of fee lenders charge. (The full term to describe this fee is “discount points.” Simply put, a point is a unit of measure that means 1 percent of the loan amount. So, if you take out a $100,000 loan, one point equals $1,000. Discount points represent additional money you can pay to the lender at closing. In return, the lender will provide you a lower interest rate on your loan.

A note on discount points...
Sometimes you can negotiate with the seller of a property to pay some of the points on your loan. Keep in mind that the discount points you pay are tax deductible. Also, realize that you will need more cash at closing if you decide to pay points. And finally, remember you have to pay for your points all at once, whereas you only pay interest on your loan as long as you have your house. So if you will be living in your house for only a short period of time, you may decide it is preferable not to pay points.

  • Interest Rate Lock-ins: While you shop for a loan, interest rates can change frequently. So it’s important to ask if the mortgage lender will offer you a rate lock-in. This can guarantee you a specified interest rate, provided the loan is closed within a set period of time. When you apply for your mortgage, you should have a good idea of when you want to close on your house. If your lock-in period expires before you go to closing, your lender is not obligated to give you the same interest rate you had locked in earlier. So, it is important to lock in for a period that will cover the time until your expected closing date. Locking in a quoted rate when rates are rising may save you thousands of dollars in interest over the life of the loan. If the rates are falling, it may be best to wait until the last possible moment before locking in.
  • Annual Percentage Rate: This percentage figure includes interest plus points and closing costs and spreads them over the life of the loan. The APR gives your “effective rate of interest” and must be disclosed to you according to federal truth-in-lending laws.

Repayment Term

A shorter repayment period means you will owe less interest. The length of your mortgage repayment period will directly impact your monthly mortgage payments. For the same mortgage principal amount, you will find that the shorter the repayment period, the higher your monthly payment will be, but the total interest you pay over the life of the loan will be less.

On the other hand, the longer your repayment period, the lower your monthly payment will be, but the total interest you’ll pay over the life of the loan will be more. Selecting a loan term involves striking a balance between how low you want your monthly mortgage payments to be versus how quickly you want and can afford to own your home debt-free.
