What does Income versus Debt Ratio have to do with buying a home in Arizona?

Nothing if you are a cash buyer.

But if you are planning on borrowing money (mortgage) then it has everything to do with whether you can qualify for a loan.  Banks and lenders are funny about loaning their money.  They want to take every precaution possible since the real estate crises to insure YOU CAN (debt to income ratio) and YOU WILL (credit history and score) repay the loan on time, every time.

Here goes…

Debt to Income Ratio

First, determine your gross monthly income. This will include any regular and recurring income that you can document. It is the average income of a 2 year time period. 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 would be counting on withdrawing money periodically from your tax deferred retirement accounts to provide funds for your monthly payments, be sure to speak to your loan officer.  The rules have changed and your retirement account funds may not be considered income in certain circumstances.  If you have questions about your specific situation, any good loan officer can review your documents.

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 ten 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 proposed housing expense, including monthly payments for taxes and insurance, should not exceed about 28% of your gross monthly income. If you don’t know what your tax and insurance expense will be, you can estimate that about 15% 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% of your gross monthly income. If it does, your application may exceed the lender’s underwriting guidelines and your loan may not be approved.

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