You have earned my respect for the wisdom of the statement
“I have little confidence in my ability to sort out all the investment strategy and timing”
If you wanted a new 30 YR loan without taking cash out, it would cut your payments over 50%.
It’s a personal decision as to whether you want a higher payment for 10 years or a lower payment for 30, with access to the extra cash now, and hopefully paying back in cheaper inflated dollars.
A $500 payment 10-20 years from now will probably not seem like much. (It doesn’t even seem like much today) Even a Wal-Mart greeter could afford that payment. 🙂 HLS
