Hi,
I'm an insurance broker so please heed my warning...
I don't know anything about the bank loan aspect of this, but from an insurance standpoint, your home is NOT COVERED by a regular homeowners policy should you rent the dwelling out. Read your contract and you will see this is true. Your claim would be denied, and there would be no legal recourse since you are not providing accurate information to the insurance company. When you purchased your homeowners policy, there was a fraud form you signed which is an industry standard.
If you should decide to rent the home, you will need one of two policies...
A DP1, DP2 or DP3 if you are renting with a standard one year lease. These are sometimes called 'dwelling fire policies'. These do not cover vacation type rentals, so be certain of your intentions before purchasing a policy. DP3 is the best form and the most expensive, and is the most recommended since it provides the best possible coverage for a landlord. Be aware that not all companies offer a DP3, so shop around.
If you should decide to rent your home as a vacation rental, you must purchase a specialty policy. These are usually brokered through Lloyds of London, and usually cost about 50% to 75% more than a standard dwelling fire policy. This is due to the fact that you have a much higher liability exposure with multiple renters coming and going.
Make sure that you get the right insurance, or you are setting yourself up for a disaster should a claim arise. One other consideration is that when you switch insurance policies or companies, your lender is notified.
Peace~
