Mortgage repayment yields big returns

Compared to Treasurys and CDs, investment's a no-brainer

One consequence of the financial crisis has been to make investment in mortgage repayment increasingly attractive. Mortgage repayment is a riskless investment that yields a return equal to the interest rate on the repaid loan. If the loan carries a 6.125 percent rate, the borrower earns that rate on the balance repaid. The yield on other investments of comparable risk, including federal government securities, CDs and money market funds, are way down. My money market funds today are yielding barely more than 1 percent.

Not so obvious but even more compelling, some borrowers in process of refinancing can earn a much higher return on partial loan repayment if the balance reduction allows them to reduce or avoid mortgage insurance coverage.
