Be sure to check out the ILMA Budget/Debt Elimination Course: https://www.sentinelcoaching.com/ilmabudget

The goal is to become debt free! At what cost? 
It depends!  

Retirement accounts may not be what you want to sell. You will have to pay taxes and penalities.  

Non-retirement investments are open to selling. Maybe downsizing is in the future, sell items and you can replace them in the new town, state, or even country that you move to!
