Qualification Calculator Makes Two Separate Calculations

Down Payment

The original qualification calculator required a 20 percent down payment. The current qualification calculator assumes a 5 percent down payment. Both calculators assume that your savings funds will have to cover closing costs as well as the down payment.

If the calculator shows that you are constrained by the down payment, there are a number of options. FHA, VA and some private mortgage insurance companies allow a lower down payment. Also, you will find that by saving up for a while, you can really increase the size of the home you can purchase.

It is a good idea to put down 20 percent if you find it possible to do so for the house that you wish to buy. However, 20 percent is a "nice-to-have" as opposed to a "must have." I have seen estimates that over 1/4 of all mortgages go to borrowers with lower down payments.

Income and Debt Ratio

Mortgage qualification, or mortgage underwriting, is a pseudo-science. The mortgage lender is trying to determine whether or not you can and will meet the payments on the mortgage. Because no one can predict exactly who will meet the payments and who will default, mistakes will be made. Some "good" borrowers will be turned down, and some "bad" borrowers will receive loans.

What this means to you as a borrower is that your application for mortgage credit will be evaluated according to some rules of thumb that appear to be precise, such as "the ratio of your monthly payment to your income should not exceed 28 percent," or "the ratio of your monthly payments plus monthly non-housing debt to your income should not exceed 36 percent." However, everyone knows that these rules of thumb are not completely accurate.

Because the rules of thumb are simplistic, lenders are not rigid in using them. On the one hand, you can "pass the test" of having enough income to satisfy the 28/36 percent ratios and still get turned down for a mortgage loan. On the other hand, you mail "fail" to meet the test and still have your application accepted. These exceptions are discussed below.

Risk Factors

Factors that could disqualify a borrower who "passes" the simple ratio test include:

• Poor Credit History - If you have a previous bankruptcy or mortgage default on your record, lenders will be reluctant to grant a new mortgage. However, an occasional late payment on a monthly credit card bill will not disqualify you for a mortgage.
  
• Unstable Income Source
  If your income is subject to fluctuations (for example, if you are paid on commission), the lender will qualify you on the basis of a conservative estimate of likely earnings. Self-employed borrowers receive particularly close scrutiny.
  
• Inadequate Cash Reserves
  If after the down payment you will have less cash in reserve than you would need to meet three mortgage payments, the lender may conclude that your loan could go bad if you were laid off briefly or had some other minor financial problem.

Qualifying in Spite of a High Ratio

On the other hand, do not be discouraged if the pre-qualification calculator does not show that you can obtain as large a loan as you like. Lenders will try as hard as they can to meet your needs. Among the options that they have are:

• Accepting a Higher Ratio - The lender can choose to allow you to pay more than 28 percent of your income to meet mortgage payments.

However, usually the lender must find some other factor in your favor. For example, if the new payment will represent little or no increase from what you previously were paying in rent or a mortgage payment, this may help. Lenders also take into account compensating factors such as a large down payment or sizable cash reserves.

Alternative Loan Products

If you do not qualify for a 30-year fixed rate loan, you may qualify for the same loan amount if a lower-rate mortgage can be found. However, few prudent lenders will use the initial rate on a short-term adjustable rate mortgage (ARM) as the qualifying rate. One rule of thumb is to use the maximum possible second-year rate. This often is below the 30-year rate.
