One strategy would be to be make regular principal contributions in addition to the payments so that it will eliminate the debt by the target retirement date.
Let’s say that a homeowner refinanced their $200,000 mortgage at 4% last year with the first payment due on May 1, 2012. Under normal amortization, the home would be paid for at the end of the term; 30 years in this example.
By making additional principal contributions with each payment, it would accelerate the payoff on the home. An extra $250.00 a month would pay off the mortgage in 10 years. $524.55 extra with each payment would pay off the loan in 15 years; and $796.23 would pay off the loan in 12 years.
Having a home paid for at retirement has the obvious benefit of no house payment. It is also a substantial asset that could be borrowed against or sold if unanticipated events should occur.
Another strategy might involve purchasing a smaller home now to use as a rental that you intend to live when you retire; see Retirement Home Now.
