• Sufficient income to support the monthly mortgage payment
• Enough cash to cover the down payment
• Sufficient cash to cover normal closing costs and related expenses (explained below)
• A good credit background that indicates your payment history or "willingness to pay"
• Sufficient appraisal value, which shows the house is at least equal to the purchase price
• In some instances, a cash reserve equivalent to two monthly mortgage payments

Closing costs, or settlement costs, are paid when the home buyer and the seller meet to exchange the necessary papers for the house to be legally transferred. On the average, closing costs run approximately 2% to 3% of the house price. This percentage may vary, depending on where you live.

Examples of closing costs are the loan origination fee (if not already paid), points, prepaid homeowner's insurance, appraisal fee, lawyer's fee, recording fee, title search and insurance, tax adjustments, agent commissions, mortgage insurance (if you are putting less than 20% down) and other expenses. Your mortgage professional will give you a more exact estimate of your closing costs.

Points are finance charges that are calculated at closing. Each point equals 1% of the loan amount. For example, 2 points on a $100,000 loan equals $2,000. The more points you pay, the lower your interest rate will be. In some cases, you may be able to finance the points.

So How Much of a Mortgage Can You Afford?

There are two basic formulas commonly used to determine how much of a mortgage you can reasonably afford. These formulas are called qualifying ratios because they estimate the amount of money you should spend on mortgage payments in relation to your income and other expenses.

It is important to remember that the following ratios may vary and each application is handled on an individual basis, so the guidelines are just that -- guidelines. There are many affordability programs, both government and conventional, that have more lenient requirements for low- and moderate-income families.

Many of these programs involve financial counseling for low- and moderate-income people interested in buying a home and in return, offer more lenient requirements.

Generally speaking, to qualify for conventional loans, housing expenses should not exceed 26% to 28% of your gross monthly income. For FHA loans, the ratio is 29% of gross monthly income. Monthly housing costs include the mortgage principal, interest, taxes and insurance, often abbreviated PITI. For example, if your annual income is $30,000, your gross monthly income is $2,500, times 28% = $700. So you would probably qualify for a conventional home loan that requires monthly payments of $700.

Any expenses that extend 11 months or more into the future are termed long-term debt, such as a car loan. Total monthly costs, including PITI and all other long-term debt, should equal no greater than 33% to 36% of your gross monthly income for conventional loans. Using the same example, $2,500 x 36% = $900. So the total of your monthly housing expenses plus any long-term debts each month cannot exceed $900. For FHA the ratio is 41%.

29% of gross monthly income - FHA

When budgeting to buy a home, it is important to allow enough money for additional expenses such as maintenance and insurance costs. If you are purchasing an existing home, gather information such as utility cost averages and maintenance costs from previous owners or tenants to help you better prepare for homeownership.

Homeowner's insurance or property insurance is another cost you will have to consider. The lending institution holding the mortgage will require insurance in an amount sufficient to cover the loan. However, to protect the full value of your investment, you might want to consider purchasing insurance that provides the full replacement cost if the home is destroyed. Some insurance only provides a fixed dollar amount which may be insufficient to rebuild a badly damaged house.
