Probably, but I refied two years ago at 5%. CU says 4% for a 30 year. Dunno if that's really worth the hassle considering my mortgage is well under $200k (we bought our house when the neighborhood was "emerging". Handyman special! Just bring a machete to run off the crackheads!)With rates this low taking a 30 year and investing the difference in the payments would yield much higher net worth/wealth.
