Range ventilation needed?

[Mat O'Grady]

Hello all, 

I am working on my first flip and we came up with an open kitchen with an island that has the oven in it. I posted earlier with the design and someone brought up the fact of the range needing ventilation. I was thinking of putting anything in. 

What do you normally do for your houses? The ARV is approximately 240k and it is most likely a starter home for an FHA buyer.

Thanks,

Mat
