4% is 4% unless it's not.Yeah
That’s the part that is usually overlooked
Y’all expert eggheads chime in here and correct me if I’m wrong
I barely graduated high school , and flunked a lot of math classes .
But as I understand it , When you prepay , your gain or return is whatever your interest rate is ,let’s say it’s 4%
Sure you can usually make 4% gain in the stock market
But when you prepay , you’re getting that 4% return multiplied by EVERY YEAR that’s left on your mortgage
If you have 27 years left , you’re getting a 4% return , 27 times
Correct?
It's an annualized rate, same as your stock market return or interest on a savings account. When you invest in the stock market, you also [hope to] get a return every year.
One wrinkle is tax treatment. For most of us here mortgage interest is effectively no longer deductible since the tax reform made taking a standard deduction more beneficial. This means you're paying mortgage interest, and save on mortgage interest by prepaying, with aftertax dollars. To compare to other investing options, you need to figure out an equivalent pretax rate which for 4% should be somewhere in 5.0%-6.5% range depending on many individual factors.
