As you think about applying for a home loan, you need to consider your personal finances. How much you earn versus how much you owe will likely determine how much a lender will allow you to borrow.

First, determine your gross monthly income. This will include any regular and recurring income that you can document. Unfortunately, if you can't document the income or it doesn't show up on your tax return, then you can't use it to qualify for a loan. However, you can use unearned sources of income such as alimony or lottery payoffs. And if you own income-producing assets such as real estate or stocks, the income from those can be estimated and used in this calculation. If you have questions about your specific situation, any good loan officer can review the rules.

Next, calculate your monthly debt load. This includes all monthly debt obligations like credit cards, installment loans, car loans, personal debts or any other ongoing monthly obligation like alimony or child support. If it is revolving debt like a credit card, use the minimum monthly payment for this calculation. If it is installment debt, use the current monthly payment to calculate your debt load. And you don't have to consider a debt at all if it is scheduled to be paid off in less than six months. Add all this up and it is a figure we'll call your monthly debt service.

In a nutshell, most lenders don't want you to take out a loan that will overload your ability to repay everybody you owe. Although every lender has slightly different formulas, here is a rough idea of how they look at the numbers.

Typically, your monthly housing expense, including monthly payments for taxes and insurance, should not exceed about 28 percent of your gross monthly income. If you don't know what your tax and insurance expense will be, you can estimate that about 15 percent of your payment will go toward this expense. The remainder can be used for principal and interest repayment.

In addition, your proposed monthly housing expense and your total monthly debt service combined cannot exceed about 36 percent of your gross monthly income. If it does, your application may exceed the lender's underwriting guidelines and your loan may not be approved.

Depending on your individual situation, there may be more or less flexibility in the 28 percent and 36 percent guidelines. For example, if you are able to buy the home while borrowing less than 80 percent of the home's value by making a large cash down payment, the qualifying ratios become less critical. Likewise, if Bill Gates or a rich uncle is willing to cosign on the loan with you, lenders will be much less focused on the guidelines discussed here.

Remember that there are hundreds of loan programs available in today's lending market and every one of them has different guidelines. So don't be discouraged if your dream home seems out of reach.

In addition, there are a number of factors within your control which affect your monthly payment. For example, you might choose to apply for an adjustable rate loan which has a lower initial payment than a fixed rate program. Likewise, a larger down payment has the effect of lowering your projected monthly payment

3 Easy Steps to Getting a Mortgage

Examine your finances and shop around before you apply

Shopping for a mortgage is the first step toward owning a home and perhaps the most daunting, especially if you are not prepared.

Once a simple task that meant comparing fixed rates from among perhaps a dozen or fewer savings and loan companies, the mortgage hunt today is like finding your way through a maze.

There are dozens of loan types and hundreds of loan programs available through thousands of mortgage brokers, bankers, lenders, finance companies, credit unions, even stock brokerage firms.

Contrary to popular belief, finding a mortgage doesn't begin with an application.

Education is a better first choice. Mortgage information sources are as vast as the number of mortgages available. Web sites, topical newspaper articles, mortgage books, consumer seminars and workshops, financial planners, real estate agents, mortgage brokers and lenders are all available to assist you along the way.

First and foremost, you must determine how your mortgage payment will fit your current budget and, to some extent, your future obligations 15 to 30 years down the road.

If you discover too late that you can't afford your mortgage, you'll not only face the possibility of losing the roof over your head, but you could also damage your ability to purchase a home later.

Step 1: Examine Your Finances
If you can afford to buy a home, you must then determine how much mortgage you can afford. Lenders are apt to put your loan application in the best light and qualify you for as much as they are willing to lend, which can be more than you can afford.

It's up to you to take stock of your income and expenses, both current and projected to determine what you can comfortably manage each month. Along with your mortgage payment, don't forget related insurance, taxes, homeowner association dues and any other costs rolled into the mortgage payment.

Step 2: Shopping For a Loan
When you are ready to shop for a loan you have two basic types of mortgage stores to shop -- direct lenders and mortgage brokers.

Direct lenders have money to lend. They make the final decision on your application. Brokers are intermediaries who, like you, have many lenders from which to choose. Lenders have a limited number of in-house loans available. Brokers can shop many lenders for each lenders' store of loans. If you have special financing needs and can't find a lender to suit them, an experienced broker may be able to ferret out the loan you need. Mortgage brokers, however, are paid with a slice of the amount you borrow, some more than others some less. Internet brokers today perhaps receive the smallest cut, sometimes none at all, and can prove to be a real bargain.

Along with shopping the source, you'll also have to shop loan costs, including the interest rate, broker fees, points (each point is one percent of the amount you borrow), prepayment penalties, the loan term, application fees, credit report fee, appraisal and a host of others.

Step 3: Apply For a Loan
The application process is the easy part -- provided you've gathered documents necessary to prove claims you make on the application.

The application will ask for information about your job tenure, employment stability, income, your assets (property, cars, bank accounts and investments) and your liabilities (auto loans, installment loans, mortgages, credit-card debt, household expenses and others).

The lender will run a credit check on you to take a look at your credit status, but you'll have to supply additional documentation including paycheck stubs, bank account statements, tax returns, investment earnings reports, rental agreements, divorce decrees, proof of insurance, and other documentation. If the lender deems you creditworthy, it will likely hire a professional appraisal to make sure the value of the home you are about to buy is truly worth your loan amount.
