Stearns said the borrower is taking out $50,000 in home equity. After the loan closes, the borrower will still have a 40 percent stake in the property. That translates to a healthy 60 percent loan-to-value ratio, or LTV -- a figure that reflects how much debt remains on the property. The lower the ratio, the better.
You need lots of equity to borrow from it
Home prices rose year over year for the 22nd straight month in March, according to the S&P/Case-Shiller index of home prices. That run helped 4 million mortgaged properties regain equity in 2013 and boosted Americans' overall stakes in their homes to over 50 percent for the first time in six years.
Still, lenders require a hefty amount of equity before homeowners can borrow against their home. In general, a homeowner cashing out into a fixed-rate mortgage must have at least 15 percent equity left over, or a loan-to-value ratio of 85 percent, according to rules spelled out by Fannie Mae and Freddie Mac, which guarantee the majority of U.S. home loans.
If the homeowner chooses an adjustable-rate mortgage when cashing out, then the maximum LTV is 75 percent. The LTV requirements for cash-out refis differ even more if the home is a second house, an investment property, a mobile home or a multiple-unit dwelling.
For HELOCs, lenders generally want the LTV to be 80 percent or less, says Pava Leyrer, manager of training and implementation for Northern Mortgage Services in Grand Rapids, Michigan.
"The reason why most want to keep that 20-percent stake is because it will cover the cost to take back the property in foreclosure and turn around and sell it," Leyrer says.
Lenders scrutinize total debt payments
LTV is not the only key percentage to tap home equity. The ratio between a consumer's total debt and income is also part of the qualification equation. And again, the lower the percentage, the better. The magic number, according to Fannie Mae and Freddie Mac, is 45 percent.
Lenders will add up the total monthly payment for the house, which includes principal, interest, taxes, homeowners insurance, direct liens and home association dues along with any other outstanding debt that is a legal liability. That can include child support, installment loans, credit card bills, IRS payments and even student loans that are not yet being repaid, Leyrer says.
That total debt is divided by a borrower's gross monthly income, which is comprised of base salary, commissions, bonuses and any other income such as rental income or on-time, up-to-date spousal support.
"Lenders want to see if after making your monthly debt payments, is there any money left over at the end of the month," says Dave Norris, president and chief operating officer of loanDepot.com.
And then there's the credit score
Even if a borrower's income shows ability to repay the loan, that doesn't mean the borrower will, Norris says. That's where a borrower's credit score comes in. For HELOCs, Leyrer says most borrowers with a credit score between 660 and 680 will probably qualify, but a score of 700 is "more of a shoo-in."
For cash-out refis, generally, the lowest credit score on a home that the borrower lives in is 640, according to Fannie Mae's standards. But such a loan comes with caveats. The borrower can't have an LTV ratio higher than 75 percent, must have six months of reserves in the bank and a debt-to-income ratio of 36 percent or lower. Those stipulations disappear as the credit score, LTV or debt to income improves.
