Second mortgages are similar to home equity loans, which are fixed rate, simple interest loans, recorded as a second lien on the property title deed behind the existing first mortgage. The equity in your home can be accessed without a mortgage refinance, which may save money on closing costs, and retain an existing low mortgage rate.

Alternative options for cash out, especially if you have little or no equity, can also include: cash out FHA home loans up to 85%, or unsecured personal loans. Second mortgage rates can be influenced by a number of factors such as: credit scores, the amount of the loan requested, debt to income ratio, your disposable income, and the value of your home. 

Cash out can be used for any purpose, such as home improvement, or debt consolidation. Paying off high interest debt is common, which can provide benefits, such as: reduced monthly payments, changing compound interest into simple interest, & savings from a possible tax deduction. 

When you compare mortgage rates, terms are usually offered in 5 year increments, ranging from 5 to 30 years. Fully amortized, fixed rate second mortgages are scheduled to be paid off at the end of the designated term as specified in the loan documents, with no balloon payment due. 

Second mortgage interest payments may be tax deductible for a primary home, with a limitation for the deduction set at a maximum of $100,000 or 100% of value. Check with an advisor.

The full second mortgage balance, minus any closing costs, is paid in one lump sum at the close of the loan process, unless there is an agreement to pay any third parties directly. For example, a lender may require some borrowers to pay off certain debts in order to meet the debt to income ratio. Also, if you have a line of credit or home equity loan, it must be paid off with the new loan.
