Should I hire my brother-in-law as my agent?

[Joe Dijamco]

My brother-in-law has been a Realtor for around 2 years and sold / bought ~5 homes. The family is 'kinda' pushing my wife & I to hire him because (1) he's cutting his commission (saving us money), (2) with a medium-large Realty, (3) needs the experience and (4) sales (helping out his family). 

My reservations are: I don't want to mix family with business, his lack of experience (sales too).

We just feel bad if we don't hire him because not giving him a chance to prove himself. What's the best way to approach this without causing a rift? Thanks, BP!
