Re: paying down low interest mortgages… I’ve always regretted doing this. Same regret when I made a big extra payment on my 2.8% fixed student loan.
So many solid unloved blue chips out there that pay a 4% or more dividend and have p/e of around 10.
My current faves are KMB and KHC. I also have Vanguard’s international high-div fund VYMI that pays a little more than 4% and has gone up 8% since my Sept 2019 purchase.
I think there’s a big middle area where conservative investors avoid stocks entirely or just get index funds, and aggro investors stick to rapidly growing companies.
Even if the return is the same, you can sell the stocks if you need the money, but once you repay a purchase mortgage, you’re unlikely to be able to get the same good rate again. 30 year 2nds are rare and cash out refis have a higher rate than purchase mortgages.
