Fixed rate seconds are second mortgages where you receive the entire lump sum of the mortgage at closing and the payments are amortized out for the term of the mortgage. Fixed rate seconds generally have terms for 15 or 20 years, although other terms are available. Individuals with credit problems who want to draw equity out of their homes may not qualify for a home equity line of credit and have to use a second mortgage. Rates on second mortgages are substantially higher than rates on first mortgages.
