I wonder how many of those people are paying off mortgage with what would be their savings.
(Assuming you already have enough savings to cover emergencies etc)
There's also the liquidity angle (which might be mitigated on the pay the mortgage early side with a LOC).
Am I being dumb? It's quite possible there's something I've missed.
Everyone says rates have to rise eventually. But so far we've gone 7 years of near-zero rates. If there were a dramatic shift I could take a payment holiday and put it all into savings, but I doubt I would. As for inflation, it affects any form of saving equally - nominal 4% interest is better than nominal 3% whatever that is in real terms.
