Pre-pandemic, 5 year was ~3%, in 2021 5 year was as low as ~1.4%, right now it is probably ~3.75%. With 3 rate cuts, I can see ~3% for 5 year in 2026.
If you already have a home paid off and a decent stock portfolio, can you get a loan at the same interest rate as a mortgage if you put up your home and stock portfolio as collateral? If interest rates get to near 2% that is cheap money, I would want to take out a 50% loan on my assets just to invest it.
