SD REALTOR
I am sure he is learning and he is as intelligent as anyone,not that you have said otherwise.
It is just his style to throw out everything he is working on to see what feed back he gets then he makes gains and does it again. I give him credit for trying.
In your defintition you said something I think we hear a lot and I probably say half the time when I am on the topic too. It’s very trivial.On a fixed you pay more interest at the start because the principal is larger not because the lender wants money up front. Its just a “straight note”.
Hope you are having a good day!
