Interest rate is creeping down

I have a mortgage which has a variable interested APR rate. My APR = Index + Margin. The index used in my mortgage is 12 Month Treasury average. Every month, my APR change according to this index. Tonight, I just check the trend of index last several month and it is decreasing. Since the FED reduce the prim rate in August, many index has started a trend of decreasing. This is certainly a good news for real estate market since the cost of borrowing is reduced and hopefully, it can help more people to afford the mortgage payment.
