If you (as the buyer) are being represented by a broker/agent, then yes, the broker does need to be licensed to practice real estate in the state where the property is located. Most agents do not hold licenses in multiple states if it is not necessary.
For instance, I work in the DC Metro area and need to have seperate real estate licenses for DC, Maryland, and Virginia. I cannot represent anyone, other than myself, in a sale/lease transaction outside of these three states.
