As retiredtraveler said, the importance of whatever type of retirement income is relative to your retirement expenses,
It would be much better to pay off the debt with NON-retirement money. If you liquidate your 401K to pay off debt, the amount which you draw down will still be reduced by the income taxes owed on it. If you do the removal in a year's time frame, it could also push you into another higher tax bracket if done in one year.
OR if your wife is on SS Disability, it could also mean paying some taxes on her SS amount.
Debt is important to have paid off going into retirement, including any home mortgage or car loan. Once you are free and clear of all debt, you can go into retirement paying all consumer credit on a monthly bases so no credit cards run a balance that cannot be paid on a monthly basis or more than a few months, at least to save on interest cost.
Got an emergency fund = to at least 6-9 months of recurring expenses or more.
From here you can cover things that unexpected - replace it if you have to use the funds.
If you are going to continue to live in your home, make sure that major repairs and maintenance are done and paid for before retiring. Just because a person has retired does not mean that these repairs/maintenance items stop happening.
What about health insurance before reaching Medicare age? Even Medicare is not without monthly cost, copays, deductibles or Medigap insurance premiums if that is the Medicare route which you pick.
How does the cost of living look like where you will live after retirement?
Property taxes ? Utility cost? Insurance cost - car and home?
What about if a situation arises where you or your wife, especially if she is now on disability, need some daily living care which the other cannot handle alone?
Got long term care insurance or money to pay out of pocket?
Reverse mortgages are expensive in cost. Why not get a HELOC before you retire and use this equity if you need it. It will require a monthly payment if you use it.
If you do decide to go the reverse mortgage route, use a HUD approved program and lender. Make sure that you and your wife understand it COMPLETELY. Don't just let the lender explain it - READ the doc's and ask questions BEFORE you sign on the dotted line. Also let any of your heirs know what you are doing with your home.
Personally, I'd say, you need lots more money saved before going into retirement especially early retirement. Remember you are planning for almost 30 +/- years of limited income but your expenses will be only limited by the both of you. $2500 a month will not get you too far especially if cost rise in that period of time.
