That sounds like a great deal to me - or your LTV is fantastic - as the best I can find is ~1.89% on 5 years, mostly from places I've never heard of..
I used a broker last time, but I'm not sure he found a better deal than I could have found myself, just that he did all the leg work for me.
LTV is shade under 40%, so I can get the better rates. I'm tweaking the term slightly, so we can get the budget we need. Adding 2 years, so back to 20 year term. (yes I know, should not do it really)
I need another 100k for the dream house, which actually breaks all our rules on location but it's just stunning. (Victorian conversion, open plan) So unless I go 30 year term, it's not going to happen.
In reality, probably will stick with Halifax, 20 years, as I doubt could get much better than 1.79 over 5 years.
