I just went through this. Refi’ed my current home as an owner-occupied property but may move soon.
The verbiage basically said if I moved out before 60 days, then it would constitute default and the entire balance of the loan would be due immediately.
Also said that by moving within the first 12 months, it makes the loan worth less on the open market and I would have to indemnify them against any such losses if I moved in the first 12 months.
That’s my contract. Yours may be different.
And, would anything happen if you move in 6 months ? I don’t know.
