Do you really have 30 year fixed rates? They must be ridiculous?
That’s the standard in the US. Current rates are about 2.75%, although they went below 2.5% for a bit earlier this year. Those rates are for 20% down, good credit primary residences purchases. Rates for investment or vacation properties are generally about 1-2 percentage points higher. Mortgage rates in the US are indirectly and directly subsidized by the government across a huge spectrum of programs- See FHA loans,…
But are lower shorter term fixes also available? Presumably the 30y fix is a pretty stable rate, and just acts as an upper bound? So why not go with anything available that's lower, with that as a worst case fallback that's unlikely to be materially different after x years?
