What if I want to rent a home that I already have a HELOC on?

[Craig Clifford]

I am looking into getting a HELOC on my second home and the bank wants me to declare that it is NOT a rental, which it isn't currently, and provide tax returns to prove this. Fine.

Now, coincidentally, I am thinking about renting this same property out. What happens should I get the HELOC then later rent the property? Does the bank have a type of "due" clause? How would they ever find out and if they keep getting their payments why would this be an issue?
