My financial adviser suggested that I try to have the interest rate lowered on my line of credit. So, I finally called the bank this afternoon to ask. I was told that my rate was automatically lowered by .25% per cent last week and that they couldn't go any lower unless I doubled my limit. I refused. When it's time to buy a house (hopefully in the next 18-24 mos), I'll ask my financial adviser if I'm better off having 7.5 or 12.5K of 'available credit' (combining LoC and credit card) when I start mortgage shopping.
Right now, my line of credit serves as my emergency fund because I'm making really good interest on my 'real' money and the only real emergency that could happen right now is my car going kablooey and even that isn't really an emergency since I don't really need my car. So, I really don't need much of an emergency fund, or have much need for one. Its only real purpose right now is for any credit card spillover; if I need an extra week or two to fully pay off my credit card in a given month because the pays don't line up, I take the excess from the line of credit (which has 10% less interest than the card). I pay on average 55 cents in interest when I do this; which I can more than live with even if it seems like bizarre financial planning. That 55 cents usually guarantees me a 25$ Amazon gift certificate which I use on stuff I'd be buying anyway, so I figure that I'm ahead.
