APR vs Interest Rate on Quote

[David Nunn]

Hello!

I'm in the process of buying a home, and received a quote from a lender. It has the interest rate (7.3%), and then a higher amount for APR (7.8%). I don't remember seeing this in the past, but could have just missed it. Is this common? Is it negotiable? Something I should be adding into my calculator when I run numbers?

Thanks!! -Dave
