We are about to replace our (old) one piece double oven stove with a new range and an over the range microwave. There is currently a cabinet above the top of the stove.

Can someone tell me how much clearance is needed between the bottom of the microwave and the stovetop? I'm hoping to avoid having to pull out the cabinet as we are selling the house and this is strictly for resale.

There is currently 31" from the bottom of the cabinet to the top of the current stovetop. A microwave I was looking at said it's height was 17 1/4" which I think is too close to the stove top.

thanks for your help!
