With Spring upon us, and new buyers out looking for houses, I thought today  might be a good time to review the basics of what lenders look for as they  decide to approve (or deny) mortgage applications. For at least 25 years, I have  heard them called “The 4 C’s of Underwriting”- Capacity, Credit, Cash, and  Collateral.  Guidelines and risk tolerances change, but the core criteria do  not.
CAPACITY
CAPACITY is the analysis of comparing a borrower’s income to their proposed  debt. It considers the borrower’s ability to repay the mortgage. Lenders look at  two calculations (we call ratios). The first is your Housing Ratio. It simply is  the percentage of your proposed total mortgage payment (principal &  interest, real estate taxes, homeowner’s insurance and, if applicable, flood  insurance and mortgage insurance – like PMI or the FHA MIP) divided by your  monthly, pre-tax income. A solid Housing Ratio (often called the front end  ratio) would be 28% or less; although, at times loans are approved at a  significantly higher number. That’s because your front end ratio is looked at in  conjunction with your back end ratio.
The back end ratio (referred to as your Debt Ratio) starts with that mortgage  payment calculation from the Housing Ratio and adds to it your recurring debts  that would show up on your credit report (auto loans, student loans, minimum  credit card payments, etc.) without taking into consideration some other debts  (phone bills, utility bills, cable TV). A good back ratio would be 40% or less.  However, loans sometimes are granted with higher debt ratios. Understand that  every application is different. Income can be impacted by overtime, night  differential, bonuses, job history, unreimbursed expenses, commission, as well  as other factors. Similarly, how your debts are considered can vary. Consult an  experienced loan officer to determine how the underwriter will calculate your  numbers.
CREDIT
CREDIT is the statistical prediction of a  borrower’s future payment likelihood. By reviewing the past factors (payment  history, total debt compared to total available debt, the types of monies:  revolving credit vs. installment debt outstanding) a credit score is assigned  each borrower which reflects the anticipated repayment. The higher your score,  the lower the risk to the lender which usually results in better loan terms for  the borrower. Your loan officer will look to run your credit early on to see  what challenges may (or may not) present themselves.
CASH
CASH is a review of your asset picture after you close. There are really two  components – cash in the deal and cash in reserves. Simply put, the bigger your  down payment (the more of your own money at risk) the stronger the loan  application. At the same time, the more money you have in reserve after closing  the less likely you are to default. Two borrowers with the same profile as far  as income ratios and credit scores have different risk levels if one has $50,000  in the bank after closing and the other has $50. There is logic here. The source  of your assets will be examined. Is it savings? Was it a gift? Was it a one-time  settlement/lottery victory/bonus? Discuss how much money you have and its  origins with your loan officer.
COLLATERAL
COLLATERAL refers to the appraisal of your home. It considers many factors –  sales of comparable homes, location of the home, size of the home, condition of  the home, cost to rebuild the home, and even rental income options. Understand  the lender does not want to foreclose (they aren’t in the real estate business),  but they do need to have something to secure the loan against, in case of  default. In today’s market, appraisers tend to be conservative in their  evaluations. Appraisals are really the only one of the 4 C’s that can’t be  determined ahead of time in most cases.
Now, each of the 4 C’s are important, but it’s really the combination  of them that is key. Strong income ratios and a large down payment with  strong reserves can offset some credit issues. Similarly, long and strong credit  histories help higher ratios….and good credit and income can overcome lesser  down payments. Talk openly and freely with your loan officer. They are on your  side, advocating for you and looking to structure your file as favorably as  possible.
