My savings are invested in the stock market, and the returns I get from that are higher than the interest on my mortgage. If I liquidated my investments to pay off the house, the savings from not paying mortgage interest would still be less than what I’d make from the market over the same period. I’d rather use the profits from my investments to cover the mortgage interest - that way I still have money left over. If I did the opposite, I’d lose that extra money.

I have enough to pay off my house right now but I'm not because the interest rate is both lower than inflation and what I earn from interest, and other invesents, plus the increase in home values. If I paid off the house today then I also wouldn't have as much in my emergency fund. I have 5 years left of the mortgage, I'm paying roughly $50/mo interest which goes down every month.

Besides what others have said, there is a mortgage interest deduction on taxes in the US. It’s basically the government saying “we want you to buy a house, so for the interest you pay on a home loan, you don’t have to pay taxes on it.” So combine that with a low rate, and it absolutely makes sense to have that debt and put the money to work elsewhere.

I'm not who you are responding to, but I'm in the same position.

Interest rate on house mortgage is around 2%, currently looking to invest in an apartment in Europe. The current rates are ~4% here, so it makes more sense to keep the cheap money from the house mortgage than to trade it for more expensive money.
