Rookie mistake - REFI means stay for a year?

[Andres Guerra]

Like everyone these days, I recently did a REFI on my home to take advantage of the low rates. However, I failed to read the fine print where it says you need to stay in your house for at least a year before moving out. I was planning on making my current house a rental property and moving to a house with a better school zone (kid will start Elementary next school year) in the near future. I could wait until the summer of next year, but it wouldn't be a full year on my REFI. 

Am I stuck in this house for a year? Even though I do want to make my house a rental property, could a bank be more lenient if the reason I want to move is truly because of the school zone? (I care more about this than making money out of the deal) I wouldn't mind waiting for the full year if not for the school. 

I've read in other threads that perhaps 6 months is enough but would like to get smarter on this topic. 

Thanks!
