The fee on a HELOC is determined by the statute under which you lend. KRS 287.710 limits the fee to $20. It is the only fee that specifically mentions the annual fee. Other statutes are silent on this fee. Many of the lenders charging the higher annual fees in KY are out-of-state banks that have imported their rates into KY.
There are two schools of thought on charging loans fees in KY. One school believes you can charge any fee unless it is specifically prohibited by statute. The other school beleives you only charge fees prescribed by statute and any additional amount is considered interest. The courts will ultimately decide which school is right. If you adhere to the later school, you never have any usury problems, but you may forego some earnings.
