If you plan to rent out first, you must disclose and apply mortgage as investment property. (The interest rate is only 0.25% higher these days - it does not worth not telling the truth)
You'll have to sign paperwork for property usage at closing. Violation could be subject to criminal charge if the lender detects and pursues (nowadays, it takes minutes online or a call or two to find out if a property is rented or is being used as a primary home).
Your hubby's job is not confirmed so does the "transfer" plan, you can not use this as an excuse.
