We are (hopefully) buying a house where we will (hopefully) live for a long time, maybe forever. We are both in our early 40s with two kids. In time we'd like to do an extension but that will cost over £100k we think so we won't be able to afford that for a good few years. Our mortgage will be about £350k which is a big loan but we do have quite a bit of equity in our current property so our LTV is good.
I just don't know what to do about fixing the mortgage rate. There's so much uncertainty about the next few years (Brexit etc etc) I'm thinking maybe we should go for 5 years. But of course the monthly cost is a bit higher. Obviously I need to speak to my partner and come to a joint decision but I wondered what others in a similar position are doing?
Thank you.
