but is it kinda rolling credit, so first years are devoted mainly to paying interest anyway, so it doesn’t matter much that principal is spread out longer, the first year apr hard restricts you anyway (that say on 300k home you have to at least be able to pay say 21k in interest with 7% apr, independent of 30 or 50 years + principal a little bit, that part dependent) (without going into calculators, vibey based it would be like 8k vs 6k +21k, 7% drop or some shit)

which, assuming my vibey estimates in correct ballpark, the market will fuck in 2 years of rises as is.
