What average interest rate should I expect to pay on a 20-year loan, if the variable rate is 4% right now?

I can get variable rate loan with a 20-year term. The current interest rate is 4%, which is based on the prime rate. I know there's no precise answer to this question, but what might I expect the overall interest rate to turn out to be? Just a ballpark answer is fine!





Thanks!|||Interest rates are very low now, probably at the lowest point possible. Most likely your interest rates will be a lot higher in a few years when interest rates return to normal, I would guess that it can easily be 8%-9%. The website below has a history of the prime rate. Unless you expect to pay off the loan in a few years, you are probably better off with a fixed rate.
