Here is a link to IRS Publication 571 which discusses 403(B) plans;
http://www.irs.gov/publications/p571/index.htmlI would assume you were a teacher or worked for a school district or some other non-profit, yes?
You have the option of rolling your 403(B) into an IRA account. Doing this will give you more flexibility with the investments available to you. Depending on how you feel about risk, you could easily double the return you are getting. You could easily get 7% yield from any number of Closed End Funds, for that matter. Rolling your 403(B) into an IRA is something you should carefully consider. This is a non-taxable event and an IRA has identical distribution rules that the 403(B) has.
Regarding paying off the loan, I don't think it is prudent to suggest a particular course of action based on the info you gave. There isn't enough to go on.
For instance;
How many years till the $65,000 would be paid off at the current schedule?
Presumably you are deducting the interest on this loan from your taxes. What is the effective interest rate then?
How much are the current monthly payments?
How much is left on the Mortgage?
Are your Mortgage and Home Equity loan payments easily managed under your current situation?
Is there any other significant debt?
I imagine your husband still works. What is his retirement savings picture like?
Does he have a pension waiting for him?
You say you are "on a pension". Is that your only income or are you otherwise employed or is there other income?
Do you have any other retirement accounts?
Does your husband?
At the $100,000 level, investors begin to have many more options available that aren't available at lower funding levels. Separately Managed Accounts, Unit Investment Trusts, etc. often have higher minimum account thresholds.
Your 403(B)/IRA type accounts should be considered the last savings you want to touch, primarily because of the tax deferral. The longer you can leave them alone, the larger the account will grow. You might just be retired for a very long time indeed.
