HbyHA - Purchasing Disability insurance early in your career certainly has benefits as mentioned already. Be careful of what you purchase however, there are some very attractive options out there right now, that may not be as great as they seem.
"We're getting an own-occupation (specialty specific), non-cancelable, no-medical exam needed deal."
There are a few ways to get this type of deal, but I am guessing the one you referenced is through Standard, is that right?
This is an attractive option for many Residents right now, and I know Standard is out there advertising full force. However, you should also be aware that their Residual benefits are not so great and they limit benefits for Mental/Nervous conditions to 24-months.
If you are not in excellent health, than this may be an even more attractive option since there is no medical required. If you are in good health though, there are some better options out there.
My advice would be for you not to rush into any decision before hearing multiple views. Own-Occupation Disability insurance is still offered by some companies, and at an affordable price. You just need to work with the right person.
Good luck!
