Danger in Using Home Equity Line to Purchase Real Estate

[Sean Salandy]

I am planning to use my home equity line of credit that I received on my primary residence to put a down payment on a rental property. During the application process for the HELOC, I told the bank that I would be using the HELOC for home improvement. My question is, if I use the line for a downpayment for a property and the bank that gave me the HELOC finds out that I used it for real estate instead of home improvement, would they call the balance due on the HELOC(request that I immediately pay the balance off)? I'm not sure how they would find out but I'm assuming if I write checks against the HELOC, they could possibly find out that way.
