Can you ride out the next 4 years and still have that option in the future to take a new job or do you plan to retire in 4 years and just be done working. I think that is a big deal. Like a lot of my military friends retire from the military and then go get a Civy job.
OP here, I plan to be finished with teaching and retired after 4 more years, but that could change depending on health, satisfaction with the job ect. In four years I will be 62 and plan on starting to draw SS or at least have that option. From that point on its basically a year to year decision.
So I called and spoke to a very well informed gal at IPERS today, I told her what I was thinking about doing, and she found my file. She is going to run the numbers and send them out tomorrow by snail mail or I will be able to see them on the web site tomorrow.
Basically the numbers that I stated were correct, $2,830 a month for life, then it could be lower if I chose a different plan. Right now I am at 30.5 years and 57 which only equals 87.5, so I would be forced to pay a 6% loss if I started collecting at the end of the school year. Not going to do that no matter what. If I get the Missouri job, I can start drawing IPERS in November, the month of my birthday, 30.5 + 58 = 88.5 in service. Every year after that I can get a 1% increase up to a total of 5% more. if I continue to teach in Iowa. She will also be sending me that figure.
I did ask if she sees a lot of educators doing this, and she replied that "yes", this is common for people that live right on the border and can bounce over to another state.
When I asked my principle today about taking the day off, her first words out of her mouth was, "tell me you are not leaving!" It told her "maybe". She said she would give me a good recommendation.
So now, its up to the interview, and if they offer the job, making a decision after running the numbers. Thanks to everyone that offered advice, it was very helpful, no matter what option I chose to take.
